Point-of-care ultrasound (POCUS) is increasingly being used by critical care physicians to augment the physical examination and guide clinical decision making, and several protocols have been established to standardize the POCUS evaluation.¹ During the COVID-19 pandemic, POCUS has been a valuable tool as standard imaging techniques were used judiciously to minimize exposure of personnel and use of personal protective equipment (PPE).²

In the US Department of Veterans Affairs (VA) New York Harbor Healthcare System (VANYHHS) intensive care unit (ICU) on initial clinical examination included POCUS, which was helpful to examine deep vein thromboses, cardiac function, and the presence and extent of pneumonia. An international expert consensus on the use of POCUS for COVID-19 published in December 2020 called for further studies defining the role of lung and cardiac ultrasound in risk stratification, outcomes, and clinical management.³

The objective of this study was to review POCUS findings and correlate them with severity of illness and 30-day outcomes in critically ill patients with COVID-19.

Methods

The study was submitted to and reviewed by the VANYHHS Research and Development committee and study approval and informed consent waiver was granted. The study was a retrospective chart review of patients admitted to the VANYHHS ICU between March and April 2020, a tertiary health care center designated as a COVID-19 hospital.

Patients admitted to the ICU aged > 18 years with a diagnosis of acute hypoxemic respiratory failure, diagnosis of COVID-19, and documentation of POCUS findings in the chart were included in the study. A patient was considered to have a COVID-19 diagnosis following a positive SARS-CoV-2 polymerase chain reaction test documented in the electronic health record (EHR). Acute respiratory failure was defined as hypoxemia < 94% and the need for either supplemental oxygen by nasal cannula > 2 L/min, high flow nasal cannula, noninvasive ventilation, or mechanical ventilation.

To minimize personnel exposure, initial patient evaluations and POCUS examinations were performed by the most senior personnel (ie, fellowship trained, board-certified pulmonary critical care attending physicians or pulmonary and critical care fellowship trainees). Three members of the team had certification in advanced critical care echocardiography by the National Board of Echocardiography and oversaw POCUS imaging. POCUS examinations were performed with a GE Heathcare Venue POCUS or handheld unit. After use, ultrasound probes and ultrasound units were disinfected with wipes designated by the manufacturer and US Environmental Protection Agency for use during the COVID-19 pandemic.

The POCUS protocol used by members of the team was as follows: POCUS lung—at least 2 anterior fields and 1 posterior/lateral field looking at the costophrenic angle on each hemithorax with a phased array or curvilinear probe. A linear probe was used to look for subpleural changes per physician discretion.^4,5 Lung ultrasound findings in anterior lung fields were documented as A lines, B lines (as defined by the bedside lung ultrasound in emergency [BLUE] protocol)anterior pleural abnormalities or consolidations.^4,5 The costophrenic point findings were documented as presence of consolidation or pleural effusion.

The POCUS cardiac examination consisted of parasternal long and short axis views, apical 4 chamber view, subcostal and inferior vena cava (IVC) view. Left ventricular (LV) ejection fraction was visually estimated as reduced or normal. Right ventricular (RV) dilation was considered present if RV size approached or exceeded LV size in the apical 4 chamber view. RV dysfunction was considered present if in addition there was flattening of interventricular septum, RV free wall hypokinesis or reduced tricuspid annular plane systolic excursion (TAPSE).⁶ IVC was documented as collapsible or plethoric by size and respirophasic variability (2 cm and 50%). Other POCUS examinations including venous compression were done at the discretion of the treating physician.⁷ POCUS was also used for the placement of central and arterial lines and to guide fluid management.⁸

The VA EHR and Venue image local archives were reviewed for patient demographics, laboratory findings, imaging studies and outcomes. All ICU attending physician and fellow notes were reviewed for POCUS lung, cardiac and vascular findings. The chart was also reviewed for management changes as a result of POCUS findings. Patients who had at minimum a POCUS lung or cardiac examination documented in the EHR were included in the study. For patients with serial POCUS the most severe findings were included.

Patients were divided into 2 groups based on 30-day outcome: discharge home vs mortality for comparison. POCUS findings were also compared by need for mechanical ventilation. Patients still hospitalized or transferred to other facilities were excluded from the analysis. A Student t test was used for comparison between the groups for continuous normally distributed variables. Linear and stepwise regression models were used to evaluate univariate and multivariate associations of baseline characteristics, biomarker, and ultrasound findings with patient outcomes. Analyses were performed using R 4.0.2 statistical software.

Results

Eighty-two patients were admitted to the VANYHHS ICU in March and April 2020, including 12 nonveterans. Sixty-four had COVID-19 and acute respiratory failure. POCUS findings were documented in 43 (67%) patients. Thirty-nine patients had documented lung examinations, and 25 patients had documented cardiac examinations. Patients were divided into 2 groups by 30-day outcome (discharge home vs mortality) for statistical analysis. Five patients who were either still hospitalized or had been transferred to another facility were excluded.

Baseline characteristics of patients included in the study stratified by 30-day outcomes are shown in Table 1. The study group was predominantly male (95%). Patients with poor 30-day outcomes were older, had higher white blood cell counts, more severe hypoxemia, higher rates of mechanical ventilation and RV dilation (Figures 1, 2, 3, 4, and 5). RV dilation was an independent predictor of mortality (odds ratio [OR], 12.0; P = .048).

Discussion

POCUS identified both lung and cardiac features that were associated with worse outcomes. While lung ultrasound abnormalities were very prevalent and associated with worse PaO₂ to FiO₂ ratios, the presence of RV dilation was associated most clearly with mortality and poor 30-day outcomes in the critical care setting.

Lung ultrasound abnormalities were pervasive in patients with acute respiratory failure and COVID-19. On linear regression we found that presence with bilateral B lines and pleural thickening was predictive of a lower PaO₂/FiO₂ (coefficient, -70; P = .005). Our study found that B lines with pleural irregularities, otherwise known as a B’ profile per the BLUE protocol, was seen in patients with severe COVID-19. Thus severe acute respiratory failure secondary to COVID-19 has similar lung ultrasound findings as non-COVID-19 acute respiratory distress syndrome (ARDS).^4,5 Based on prior lung ultrasound studies in ARDS, lung ultrasound findings can be used as an alternate to chest radiography for the diagnosis of ARDS in COVID-19 and predict the severity of ARDS.⁹ This has particular implications in overwhelmed and resource poor health care settings.

We found no difference in 30-day mortality based on lung ultrasound findings or profile, probably because of small sample size or because the findings were tabulated as profiles and not differentiated further with lung ultrasound scores.^10,11 However, there was a significant difference in RV dilation between the 2 groups by 30 days and its presence was found to be a predictor of mortality even when controlled for hypertension and diabetes mellitus (P = .048) with an OR of 12. RV dysfunction in patients with ARDS on mechanical ventilation ranges from 22 to 25% and is typically associated with high driving pressures.^12-14 The mechanism is thought to be multifactorial including hypoxemic vasoconstriction in the pulmonary vasculature in addition to the increased transpulmonary pressure.¹⁵ While all of the above are at play in COVID-19 infection, there is reported damage to the pulmonary vascular endothelium and resultant hypercoagulability and thrombosis that further increases the RV afterload.¹⁶

While RV strain and dysfunction indices done by an echocardiographer would be ideal, given the surge in infections and hospitalizations and strain on health care resources, POCUS by the treating or examining clinician was considered the only feasible way to screen a large number of patients.¹⁷ Identification of RV dilation could influence clinical management including workup for venous thromboembolic disease and optimization of lung protective strategies. Further studies are needed to understand the particular etiology and pathophysiology of COVID-19 associated RV dilation. Given increased thrombosis events in COVID-19 infection we believe a POCUS vascular examination should be included as part of evaluation especially in the presence of increased D-dimers and has been discussed above for its important role in working up RV dilation.¹⁸

Limitations

Our study has several limitations. It was retrospective in nature and involved a small group of individuals. There was some variation in POCUS examinations done at the discretion of the examining physician. We did not have a blinded observer independently review all images. Since RV dilation was documented only when RV size approached or exceeded LV size in the apical 4 chamber view representing moderate or severe dilation, we may be underreporting the prevalence in critically ill patients.

Conclusions

POCUS is an invaluable adjunct to clinical evaluation and procedures in patients with severe COVID-19 with the ability to identity patients at risk for worse outcomes. B lines with pleural thickening is a sign of severe ARDS and RV dilatation is predictive of mortality. POCUS should be made available to the treating physician for monitoring and risk stratification and can be incorporated into management algorithms.

Patients can now receive their COVID-19 vaccine and flu shot during the same visit, according to updated recommendations by the Centers for Disease Control and Prevention.

Previously, the CDC recommended that people receive their COVID-19 vaccinations alone and schedule any other vaccinations at least 2 weeks before or after their COVID-19 immunization. “This was out of an abundance of caution during a period when these vaccines were new and not due to any known safety or immunogenicity concerns,” the CDC guidance states. “However, substantial data have now been collected regarding the safety of COVID-19 vaccines currently approved or authorized by FDA.”

The guidance allowing for coadministration of COVID-19 vaccines with other immunizations, including the flu shot, was issued in mid-May 2021, and was restated in influenza vaccine recommendations released Aug. 27. The American Academy of Pediatrics soon followed suit, announcing that, for children eligible for the COVID-19 vaccine (age 12 and older), AAP recommendations allow for both the influenza and COVID-19 vaccines to be administered during the same visit.

Although there is limited data around giving COVID-19 vaccines with other vaccines, “extensive experience with non–COVID-19 vaccines has demonstrated that immunogenicity and adverse-event profiles are generally similar when vaccines are administered simultaneously as when they are administered alone,” the recommendations state. If administering other immunizations along with COVID-19 vaccines, providers should separate injection sites by at least 1 inch, the CDC recommends, and influenza vaccines that are more likely to cause a local reaction, like high-dose or the adjuvanted inactivated flu vaccine, should be administered in different limbs, if possible.

Whether someone should get their flu vaccine at the same time or separate from a COVID-19 vaccination or booster is a matter of personal preference as well as convenience, Susan Coffin, MD, MPH, an attending physician in the division of infectious diseases at Children’s Hospital of Philadelphia, said in an interview. “It basically boils down to: Will you be able to get your flu shot without any difficulty in 2 weeks’ time?” she said. “We don’t want inconvenience or difficulties in access to get the way of people getting their flu shot this year.”

Three primary care boards have issued a joint statement backing the Federation of State Medical Boards’ recent statement saying that, if physicians spread misinformation about COVID-19, their medical license could be suspended or revoked.

Leaders of the American Board of Family Medicine, the American Board of Internal Medicine, and the American Board of Pediatrics said Sept. 9 that they support FSMB’s position.

“We also want all physicians certified by our boards to know that such unethical or unprofessional conduct may prompt their respective Board to take action that could put their certification at risk,” a statement read. 

“Expertise matters, and board-certified physicians have demonstrated that they have stayed current in their field. Spreading misinformation or falsehoods to the public during a time of a public health emergency goes against everything our boards and our community of board-certified physicians stand for,” the leaders wrote.

“The evidence that we have safe, effective, and widely available vaccines against COVID-19 is overwhelming. We are particularly concerned about physicians who use their authority to denigrate vaccination at a time when vaccines continue to demonstrate excellent effectiveness against severe illness, hospitalization, and death.”
 

Small number spread false information

However, a small number of doctors continue to spread misinformation against the vaccines and communicate other false information surrounding COVID-19.

Some of the misinformation spreaders have had ultra-viral reach.

Among them is Daniel Stock, MD, a family physician in Indiana who has come out against COVID-19 vaccines. At a recent meeting of the Mt. Vernon Community School board in Indiana, he gave a speech urging the board to ignore the prevailing recommendations around COVID-19, such as test-and-trace measures.

Forbes reported in August that versions of the video of Stock›s speech on Facebook “have collected a total of 90 million engagements – a metric encompassing things such as comments, likes and shares – according to data collected by Media Matters for America, a liberal tech-watchdog group.”

This news organization published a story in August asking whether physicians who spread such information should lose their license and the question drew rapid-fire comments.

Commenters who argued with potential disciplinary actions raised questions about where the line will be drawn between misinformation and deeply held beliefs in terms of care.

Several comments centered on ivermectin, which is not approved by the Food and Drug Administration to treat COVID-19 but is enthusiastically supported as a COVID-19 treatment by a group of physicians called the Front Line COVID-19 Critical Care Alliance, whose website includes requests for donations.

‘Not consistent with standards’

As for ivermectin, David G. Nichols, MD, president and CEO of the American Board of Pediatrics, gave this news organization an example: “Spreading the notion that one would not need to get vaccinated because if you get sick you could take ivermectin is a very dangerous statement. That is not consistent with the standards of professionalism required for certification or licensure.”

Ivermectin, he noted, is not an approved treatment for COVID-19.

“To say that it is or has any benefit is a false statement. We’re not willing to allow individuals who make false statements to devalue the terrific work of tens of thousands of physicians across the United States doing work under very difficult circumstances,” Dr. Nichols said.

He continued: “To suggest treatments that are known not to be effective in exchange for treatment that is known to be effective is dangerous – and ivermectin falls under that category.”

Asked whether such suggestions could result in suspension or revocation of a physician’s license, Dr. Nichols said, “It’s the kind of thing that would certainly trigger a review.”

He said the standard for separating misinformation from personal beliefs is based on whether there is scientific evidence to support the belief.

The boards are not, with this statement, attempting to referee legitimate scientific debate, he said.

The misinformation the boards are referring to, Dr. Nichols said, is “where the evidence is 100% on one side and zero on another. And the zero is not only that the opinions or beliefs are unsupported or unsubstantiated, they are indeed harmful if followed. That’s the distinction we’re trying to make here.”

As for free-speech arguments, he said, “Free speech is a constitutional right. You can say whatever you want. The issue here is you do not have the right to expect continued professional sanction of a board certificate if you are lying to the public.”

The board statement also said: “We all look to board-certified physicians to provide outstanding care and guidance; providing misinformation about a lethal disease is unethical, unprofessional, and dangerous. In times of medical emergency, the community of expert physicians committed to science and evidence collectively shares a responsibility for giving the public the most accurate and timely health information available, so they can make decisions that work best for themselves and their families.”

In addition to Dr. Nichols, the statement was signed by Warren Newton, MD, MPH, president and CEO of the American Board of Family Medicine, and Richard J. Baron, MD, president and CEO of the American Board of Internal Medicine.

“Health care spending and health care waste is a huge problem in the U.S., including for children,” Vivian Lee, MD, of Children’s Hospital, Los Angeles, said in a presentation at the 2021 virtual Pediatric Hospital Medicine conference.

Data from a 2019 study suggested that approximately 25% of health care spending in the United States qualifies as “wasteful spending,” in categories such as overtesting, and unnecessary hospitalization, Dr. Lee said. “It is essential for physicians in hospitals to be stewards of high-value care,” she emphasized.

To combat wasteful spending and control health care costs, the Choosing Wisely campaign was created in 2012 as an initiative from the American Board of Internal Medicine Foundation. An ongoing goal of the campaign is to raise awareness among physicians and patients about potential areas of low-value services and overuse. The overall campaign includes clinician-driven recommendations from multiple medical organizations.

The PHM produced its first set of five recommendations in 2012, Dr. Lee said. These recommendations, titled “Five Things Physicians and Patients Should Question,” have been updated for 2021. The updated recommendations were created as a partnership among the Academic Pediatric Association, the American Academy of Pediatrics, and the Society of Hospital Medicine. A joint committee reviewed the latest evidence, and the updates were approved by the societies and published by the ABIM in January 2021.

“We think these recommendations truly reflect an exciting and evolving landscape for pediatric hospitalists,” Dr. Lee said. “There is a greater focus on opportunities to transition out of the hospital sooner, or avoid hospitalization altogether. There is an emphasis on antibiotic stewardship and a growing recognition of the impact that overuse may have on our vulnerable neonatal population,” she said. Several members of the Choosing Wisely panel presented the recommendations during the virtual presentation.
 

Revised recommendations

The new “Five Things Physicians and Patients Should Question” are as follows:

1. Do not prescribe IV antibiotics for predetermined durations for patients hospitalized with infections such as pyelonephritis, osteomyelitis, and complicated pneumonia. Consider early transition to oral antibiotics.

Many antibiotic doses used in clinical practice are preset durations that are not based on high-quality evidence, said Mike Tchou, MD, of Children’s Hospital of Colorado in Aurora. However, studies now show that earlier transition to enteral antibiotics can improve a range of outcomes including neonatal UTIs, osteomyelitis, and complicated pneumonia, he said. Considering early transition based on a patient’s response can decrease adverse events, pain, length of stay, and health care costs, he explained.

2. Do not continue hospitalization in well-appearing febrile infants once bacterial cultures (i.e., blood, cerebrospinal, and/or urine) have been confirmed negative for 24-36 hours, if adequate outpatient follow-up can be assured.

Recent data indicate that continuing hospitalization beyond 24-36 hours of confirmed negative bacterial cultures does not improve clinical outcomes for well-appearing infants admitted for concern of serious bacterial infection, said Paula Soung, MD, of Children’s Wisconsin in Milwaukee. In fact, “blood culture yield is highest in the first 12-36 hours after incubation with multiple studies demonstrating > 90% of pathogen cultures being positive by 24 hours,” Dr. Soung said. “If adequate outpatient follow-up can be assured, discharging well-appearing febrile infants at 24-36 hours after confirming cultures are negative has many positive outcomes,” she said.

3. Do not initiate phototherapy in term or late preterm well-appearing infants with neonatal hyperbilirubinemia if their bilirubin is below levels at which the AAP guidelines recommend treatment.

In making this recommendation, “we considered that the risk of kernicterus and cerebral palsy is extremely low in otherwise healthy term and late preterm newborns,” said Allison Holmes, MD, of Children’s Hospital at Dartmouth-Hitchcock, Manchester, N.H. “Subthreshold phototherapy leads to unnecessary hospitalization and its associated costs and harms,” and data show that kernicterus generally occurs close to 40 mg/dL and occurs most often in infants with hemolysis, she added.

The evidence for the recommendations included data showing that, among other factors, 8.6 of 100,000 babies have a bilirubin greater than 30 mg/dL, said Dr. Holmes. Risks of using subthreshold phototherapy include increased length of stay, increased readmissions, and increased costs, as well as decreased breastfeeding, bonding with parents, and increased parental anxiety. “Adding prolonged hospitalization for an intervention that might not be necessary can be stressful for parents,” she said.

4. Do not use broad-spectrum antibiotics such as ceftriaxone for children hospitalized with uncomplicated community-acquired pneumonia. Use narrow-spectrum antibiotics such as penicillin, ampicillin, or amoxicillin.

Michelle Lossius, MD, of the Shands Hospital for Children at the University of Florida, Gainesville, noted that the recommendations reflect IDSA guidelines from 2011 advising the use of ampicillin or penicillin for this population of children. More recent studies with large populations support the ability of narrow-spectrum antibiotics to limit the development of resistant organisms while achieving the same or better outcomes for children hospitalized with CAP, she said.

5. Do not start IV antibiotic therapy on well-appearing newborn infants with isolated risk factors for sepsis such as maternal chorioamnionitis, prolonged rupture of membranes, or untreated group-B streptococcal colonization. Use clinical tools such as an evidence-based sepsis risk calculator to guide management.

“This recommendation combines other recommendations,” said Prabi Rajbhandari, MD, of Akron (Ohio) Children’s Hospital. The evidence is ample, as the Centers for Disease Control and Prevention recommends the use of sepsis calculators to guide clinical management in sepsis patients, she said.

Data comparing periods before and after the adoption of a sepsis risk calculator showed a significant reduction in the use of blood cultures and antibiotics, she noted. Other risks of jumping to IV antibiotics include increased hospital stay, increased parental anxiety, and decreased parental bonding, Dr. Rajbhandari added.

Next steps include how to prioritize implementation, as well as deimplementation of outdated practices, said Francisco Alvarez, MD, of Lucile Packard Children’s Hospital, Palo Alto, Calif. “A lot of our practices were started without good evidence for why they should be done,” he said. Other steps include value improvement research; use of dashboards and benchmarking; involving other stakeholders including patients, families, and other health care providers; and addressing racial disparities, he concluded.

The presenters had no financial conflicts to disclose. The conference was sponsored by the Academic Pediatric Association, the American Academy of Pediatrics, and the Society of Hospital Medicine.

Cases of child COVID-19 set a new 1-week record and the total number of children infected during the pandemic passed 5 million, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

The nearly 282,000 new cases reported in the United States during the week ending Sept. 2 broke the record of 211,000 set in mid-January and brought the cumulative count to 5,049,465 children with COVID-19 since the pandemic began, the AAP and the CHA said in their weekly COVID report.

Hospitalizations in children aged 0-17 years have also reached record levels in recent days. The highest daily admission rate since the pandemic began, 0.51 per 100,000 population, was recorded on Sept. 2, less than 2 months after the nation saw its lowest child COVID admission rate for 1 day: 0.07 per 100,000 on July 4. That’s an increase of 629%, according to data from the Centers for Disease Control and Prevention.

Vaccinations in children, however, did not follow suit. New vaccinations in children aged 12-17 years dropped by 4.5% for the week ending Sept. 6, compared with the week before. Initiations were actually up almost 12% for children aged 16-17, but that was not enough to overcome the continued decline among 12- to 15-year-olds, the CDC said on its COVID Data Tracker.

Despite the decline in new vaccinations, those younger children passed a noteworthy group milestone: 50.9% of all 12- to 15-year-olds now have received at least one dose, with 38.6% having completed the regimen. The 16- to 17-year-olds got an earlier start and have reached 58.9% coverage for one dose and 47.6% for two, the CDC said.

A total of 12.2 million children aged 12-17 years had received at least one dose of COVID vaccine as of Sept. 6, of whom almost 9.5 million are fully vaccinated, based on the CDC data.

At the state level, Vermont has the highest rates for vaccine initiation (75%) and full vaccination (65%), with Massachusetts (75%/62%) and Connecticut (73%/59%) just behind. The other end of the scale is occupied by Wyoming (28% initiation/19% full vaccination), Alabama (32%/19%), and North Dakota (32%/23%), the AAP said in a separate report.

In a recent letter to the Food and Drug Administration, AAP President Lee Savio Beers, MD, said that the “Delta variant is surging at extremely alarming rates in every region of America. This surge is seriously impacting all populations, including children.” Dr. Beers urged the FDA to work “aggressively toward authorizing safe and effective COVID-19 vaccines for children under age 12 as soon as possible.”

Cases of child COVID-19 set a new 1-week record and the total number of children infected during the pandemic passed 5 million, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

Autoeczematization (AE), or id reaction, is a disseminated eczematous reaction that occurs days or weeks after exposure to a primary stimulus, resulting from a release of antigen(s). Whitfield¹ first described AE in 1921, when he postulated that the id reaction was due to sensitization of the skin after a primary stimulus. He called it “a form of auto-intoxication derived from changes in the patient’s own tissues.”¹ The exact prevalence of id reactions is unknown; one study showed that 17% of patients with dermatophyte infections developed an id reaction, typically tinea pedis linked with vesicles on the palms.² Tinea capitis is one of the most common causes of AE in children, which is frequently misdiagnosed as a drug reaction. Approximately 37% of patients diagnosed with stasis dermatitis develop an id reaction (Figure 1). A history of contact dermatitis is common in patients presenting with AE.^2-6

Pathophysiology of Id Reactions

An abnormal immune response against autologous skin antigens may be responsible for the development of AE. Shelley⁵ postulated that hair follicles play an important role in id reactions, as Sharquie et al⁶ recently emphasized for many skin disorders. The pathogenesis of AE is uncertain, but circulating T lymphocytes play a role in this reaction. Normally, T cells are activated by a release of antigens after a primary exposure to a stimulus. However, overactivation of these T cells induces autoimmune reactions such as AE.⁷ Activated T lymphocytes express HLA-DR and IL-2 receptor, markers elevated in the peripheral blood of patients undergoing id reactions. After treatment, the levels of activated T lymphocytes decline. An increase in the number of CD25⁺ T cells and a decrease in the number of suppressor T cells in the blood may occur during an id reaction.^7-9 Keratinocytes produce proinflammatory cytokines, such as thymic stromal erythropoietin, IL-25, and IL-33, that activate T cells.^10-12 Therefore, the most likely pathogenesis of an id reaction is that T lymphocytes are activated at the primary reaction site due to proinflammatory cytokines released by keratinocytes. These activated T cells then travel systemically via hematogenous dissemination. The spread of activated T lymphocytes produces an eczematous reaction at secondary locations distant to the primary site.⁹

Clinical and Histopathological Features of Id Reactions

Clinically, AE is first evident as a vesicular dissemination that groups to form papules or nummular patches and usually is present on the legs, feet, arms, and/or trunk (Figure 2). The primary dermatitis is localized to the area that was the site of contact to the offending stimuli. This localized eczematous eruption begins with an acute or subacute onset. It has the appearance of small crusted vesicles with erythema (Figure 1). The first sign of AE is vesicles presenting near the primary site on flexural surfaces or on the hands and feet. A classic example is tinea pedis linked with vesicles on the palms and sides of the fingers, resembling dyshidrotic eczema. Sites of prior cutaneous trauma, such as dermatoses, scars, and burns, are common locations for early AE. In later stages, vesicles disseminate to the legs, arms, and trunk, where they group to form papules and nummular patches in a symmetrical pattern.^5,13-15 These lesions may be extremely pruritic. The pruritus may be so intense that it interrupts daily activities and disrupts the ability to fall or stay asleep.¹⁶

Histologically, biopsy specimens show psoriasiform spongiotic dermatitis with mononuclear cells contained in the vesicles. Interstitial edema and perivascular lymphohistiocytic infiltrates are evident. Eosinophils also may be present. This pattern is not unique toid reactions.^17-19 Although AE is a reaction pattern that may be due to a fungal or bacterial infection, the etiologic agent is not evident microscopically within the eczema itself.

Etiology of Id Reactions

Id reactions most commonly occur from either stasis dermatitis or tinea pedis, although a wide variety of other causes should be considered. Evaluation of the primary site rather than the id reaction may identify an infectious or parasitic agent. Sometimes the AE reaction is specifically named: dermatophytid with dermatophytosis, bacterid with a bacterial infectious process, and tuberculid with tuberculosis. Similarly, there may be reactions to underlying candidiasis, sporotrichosis, histoplasmosis, and other fungal infections that can cause a cutaneous id reaction.^18,20-22Mycobacterium species, Pseudomonas, Staphylococcus, and Streptococcus are bacterial causes of AE.^15,23-26 Viral infections that can cause an id reaction are herpes simplex virus and molluscum contagiosum.^27-29 Scabies, leishmaniasis, and pediculosis capitis are parasitic infections that may be etiologic.^14,30,31 In addition, noninfectious stimuli besides stasis dermatitis that can produce id reactions include medications, topical creams, tattoo ink, sutures, radiotherapy, and dyshidrotic eczema. The primary reaction to these agents is a localized dermatitis followed by the immunological response that induces a secondary reaction distant from the primary site.^17,18,32-38

Differential Diagnoses

Differential diagnoses include other types of eczema and some vesicular eruptions. Irritant contact dermatitis is another dermatosis that presents as a widespread vesicular eruption due to repetitive exposure to toxic irritants. The rash is erythematous with pustules, blisters, and crusts. It is only found in areas directly exposed to irritants, as opposed to AE, which spreads to areas distant to the primary reaction site. Irritant contact dermatitis presents with more of a burning sensation, whereas AE is more pruritic.^39,40 Allergic contact dermatitis presents with erythematous vesicles and papules and sometimes with bullae. There is edema and crust formation, which often can spread past the point of contact in later stages. Similar to AE, there is intense pruritus. However, allergic contact dermatitis most commonly is caused by exposure to metals, cosmetics, and fragrances, whereas infectious agents and stasis dermatitis are the most common causes of AE.^40,41 It may be challenging to distinguish AE from other causes of widespread eczematous dissemination. Vesicular eruptions sometimes require distinction from AE, including herpetic infections, insect bite reactions, and drug eruptions.^18,42

Treatment

The underlying condition should be treated to mitigate the inflammatory response causing the id reaction. If not skillfully orchestrated, the id reaction can reoccur. For infectious causes of AE, an antifungal, antibacterial, antiviral, or antiparasitic should be given. If stasis dermatitis is responsible for the id reaction, compression stockings and leg elevation are indicated. The id reaction itself is treated with systemic or topical corticosteroids and wet compresses if acute. The goal of these treatments is to reduce patient discomfort caused by the inflammation and pruritus.^18,43

Conclusion

Id reactions are an unusual phenomenon that commonly occurs after fungal skin infections and stasis dermatitis. T lymphocytes and keratinocytes may play a key role in this reaction, with newer research further delineating the process and possibly providing enhanced treatment options. Therapy focuses on treating the underlying condition, supplemented with corticosteroids for the autoeczema.

Hospitalized COVID-19 patients at increased risk for respiratory failure showed significant improvement after treatment with anakinra, compared with placebo, based on data from a phase 3, randomized trial of nearly 600 patients who also received standard of care treatment.

Anakinra, a recombinant interleukin (IL)-1 receptor antagonist that blocks activity for both IL-1 alpha and beta, showed a 70% decrease in the risk of progression to severe respiratory failure in a prior open-label, phase 2, proof-of-concept study, wrote Evdoxia Kyriazopoulou, MD, PhD, of National and Kapodistrian University of Athens, and colleagues.

Previous research has shown that soluble urokinase plasminogen activator receptor (suPAR) serum levels can signal increased risk of progression to severe disease and respiratory failure in COVID-19 patients, they noted.

Supported by these early findings, “the SAVE-MORE study (suPAR-guided anakinra treatment for validation of the risk and early management of severe respiratory failure by COVID-19) is a pivotal, confirmatory, phase 3, double-blind, randomized controlled trial that evaluated the efficacy and safety of early initiation of anakinra treatment in hospitalized patients with moderate or severe COVID-19,” the researchers said.

In the SAVE-MORE study published Sept. 3 in Nature Medicine, the researchers identified 594 adults with COVID-19 who were hospitalized at 37 centers in Greece and Italy and at risk of progressing to respiratory failure based on plasma suPAR levels of at least 6 ng/mL.

The primary objective was to assess the impact of early anakinra treatment on the clinical status of COVID-19 patients at risk for severe disease according to the 11-point, ordinal World Health Organization Clinical Progression Scale (WHO-CPS) at 28 days after starting treatment. All patients received standard of care, which consisted of regular monitoring of physical signs, oximetry, and anticoagulation. Patients with severe disease by the WHO definition were also received 6 mg of dexamethasone intravenously daily for 10 days. A total of 405 were randomized to anakinra and 189 to placebo. Approximately 92% of the study participants had severe pneumonia according to the WHO classification for COVID-19. The average age of the patients was 62 years, 58% were male, and the average body mass index was 29.5 kg/m².

At 28 days, 204 (50.4%) of the anakinra-treated patients had fully recovered, with no detectable viral RNA, compared with 50 (26.5%) of the placebo-treated patients (P < .0001). In addition, significantly fewer patients in the anakinra group had died by 28 days (13 patients, 3.2%), compared with patients in the placebo group (13 patients, 6.9%).

The median decrease in WHO-CPS scores from baseline to 28 days was 4 points in the anakinra group and 3 points in the placebo group, a statistically significant difference (P < .0001).

“Overall, the unadjusted proportional odds of having a worse score on the 11-point WHO-CPS at day 28 with anakinra was 0.36 versus placebo,” and this number remained the same in adjusted analysis, the researchers wrote.

All five secondary endpoints on the WHO-CPS showed significant benefits of anakinra, compared with placebo. These included an absolute decrease of WHO-CPS at day 28 and day 14 from baseline; an absolute decrease of Sequential Organ Failure Assessment scores at day 7 from baseline; and a significantly shorter mean time to both hospital and ICU discharge (1 day and 4 days, respectively) with anakinra versus placebo.

Follow-up laboratory data showed a significant increase in absolute lymphocyte count at 7 days, a significant decrease in circulating IL-6 levels at 4 and 7 days, and significantly decreased plasma C-reactive protein (CRP) levels at 7 days.

Serious treatment-emergent adverse events were reported in 16% with anakinra and in 21.7% with placebo; the most common of these events were infections (8.4% with anakinra and 15.9% with placebo). The next most common serious treatment-emergent adverse events were ventilator-associated pneumonia, septic shock and multiple organ dysfunction, bloodstream infections, and pulmonary embolism. The most common nonserious treatment-emergent adverse events were an increase of liver function tests and hyperglycemia (similar in anakinra and placebo groups) and nonserious anemia (lower in the anakinra group).

The study findings were limited by several factors, including the lack of patients with critical COVID-19 disease and the challenge of application of suPAR in all hospital settings, the researchers noted. However, “the results validate the findings of the previous SAVE open-label phase 2 trial,” they said. The results suggest “that suPAR should be measured upon admission of all patients with COVID-19 who do not need oxygen or who need nasal or mask oxygen, and that, if suPAR levels are 6 ng/mL or higher, anakinra treatment might be a suitable therapy,” they concluded.
 

Cytokine storm syndrome remains a treatment challenge

“Many who die from COVID-19 suffer hyperinflammation with features of cytokine storm syndrome (CSS) and associated acute respiratory distress syndrome,” wrote Randy Q. Cron, MD, and W. Winn Chatham, MD, of the University of Alabama at Birmingham, and Roberto Caricchio, MD, of Temple University, Philadelphia, in an accompanying editorial. They noted that the SAVE-MORE trial results contrast with another recent randomized trial of canakinumab, which failed to show notable benefits, compared with placebo, in treating hospitalized patients with COVID-19 pneumonia.

“There are some key differences between these trials, one being that anakinra blocks signaling of both IL-1 alpha and IL-1 beta, whereas canakinumab binds only IL-1 beta,” the editorialists explained. “SARS-CoV-2–infected endothelium may be a particularly important source of IL-1 alpha that is not targeted by canakinumab,” they noted.

Additional studies have examined IL-6 inhibition to treat COVID-19 patients, but data have been inconsistent, the editorialists said.

“One thing that is clearly emerging from this pandemic is that the CSS associated with COVID-19 is relatively unique, with only modestly elevated levels of IL-6, CRP, and ferritin, for example,” they noted. However, the SAVE-MORE study suggests that more targeted approaches, such as anakinra, “may allow earlier introduction of anticytokine treatment” and support the use of IL-1 blockade with anakinra for cases of severe COVID-19 pneumonia.
 

Predicting risk for severe disease

“One of the major challenges in the management of patients with COVID-19 is identifying patients at risk of severe disease who would warrant early intervention with anti-inflammatory therapy,” said Salim Hayek, MD, medical director of the University of Michigan’s Frankel Cardiovascular Center Clinics, in an interview. “We and others had found that soluble urokinase plasminogen activator receptor (suPAR) levels are the strongest predictor of severe disease amongst biomarkers of inflammation,” he said. “In this study, patients with high suPAR levels derived benefit from anakinra, compared to those with placebo. This study is a great example of how suPAR levels could be used to identify high-risk patients that would benefit from therapies targeting inflammation,” Dr. Hayek emphasized.

“The findings are in line with the hypothesis that patients with the highest degrees of inflammation would benefit the best from targeting the hyperinflammatory cascade using anakinra or other interleukin antagonists,” Dr. Hayek said. “Given suPAR levels are the best predictors of high-risk disease, it is not surprising to see that patients with high levels benefit from targeting inflammation,” he noted.

The take-home message for clinicians at this time is that anakinra effectively improves outcomes in COVID-19 patients with high suPAR levels, Dr. Hayek said. “SuPAR can be measured easily at the point of care. Thus, a targeted strategy using suPAR to identify patients who would benefit from anakinra appears to be viable,” he explained.

However, “Whether anakinra is effective in patients with lower suPAR levels (<6 ng/mL) is unclear and was not answered by this study,” he said. “We eagerly await results of other trials to make that determination. Whether suPAR levels can also help guide the use of other therapies for COVID-19 should be explored and would enhance the personalization of treatment for COVID-19 according to the underlying inflammatory state,” he added.

The SAVE-MORE study was funded by the Hellenic Institute for the Study of Sepsis and Sobi, which manufactures anakinra. Some of the study authors reported financial relationships with Sobi and other pharmaceutical companies.

Dr. Cron and Dr. Chatham disclosed having received grant support from Sobi for investigator-initiated clinical trials, and Dr. Caricchio disclosed serving as a consultant to GlaxoSmithKline, Johnson & Johnson, Aurinia, and Bristol-Myers Squibb. Dr. Hayek had no relevant financial conflicts to disclose.

Hospitalized COVID-19 patients at increased risk for respiratory failure showed significant improvement after treatment with anakinra, compared with placebo, based on data from a phase 3, randomized trial of nearly 600 patients who also received standard of care treatment.

Anakinra, a recombinant interleukin (IL)-1 receptor antagonist that blocks activity for both IL-1 alpha and beta, showed a 70% decrease in the risk of progression to severe respiratory failure in a prior open-label, phase 2, proof-of-concept study, wrote Evdoxia Kyriazopoulou, MD, PhD, of National and Kapodistrian University of Athens, and colleagues.

Previous research has shown that soluble urokinase plasminogen activator receptor (suPAR) serum levels can signal increased risk of progression to severe disease and respiratory failure in COVID-19 patients, they noted.

Supported by these early findings, “the SAVE-MORE study (suPAR-guided anakinra treatment for validation of the risk and early management of severe respiratory failure by COVID-19) is a pivotal, confirmatory, phase 3, double-blind, randomized controlled trial that evaluated the efficacy and safety of early initiation of anakinra treatment in hospitalized patients with moderate or severe COVID-19,” the researchers said.

In the SAVE-MORE study published Sept. 3 in Nature Medicine, the researchers identified 594 adults with COVID-19 who were hospitalized at 37 centers in Greece and Italy and at risk of progressing to respiratory failure based on plasma suPAR levels of at least 6 ng/mL.

The primary objective was to assess the impact of early anakinra treatment on the clinical status of COVID-19 patients at risk for severe disease according to the 11-point, ordinal World Health Organization Clinical Progression Scale (WHO-CPS) at 28 days after starting treatment. All patients received standard of care, which consisted of regular monitoring of physical signs, oximetry, and anticoagulation. Patients with severe disease by the WHO definition were also received 6 mg of dexamethasone intravenously daily for 10 days. A total of 405 were randomized to anakinra and 189 to placebo. Approximately 92% of the study participants had severe pneumonia according to the WHO classification for COVID-19. The average age of the patients was 62 years, 58% were male, and the average body mass index was 29.5 kg/m².

At 28 days, 204 (50.4%) of the anakinra-treated patients had fully recovered, with no detectable viral RNA, compared with 50 (26.5%) of the placebo-treated patients (P < .0001). In addition, significantly fewer patients in the anakinra group had died by 28 days (13 patients, 3.2%), compared with patients in the placebo group (13 patients, 6.9%).

The median decrease in WHO-CPS scores from baseline to 28 days was 4 points in the anakinra group and 3 points in the placebo group, a statistically significant difference (P < .0001).

“Overall, the unadjusted proportional odds of having a worse score on the 11-point WHO-CPS at day 28 with anakinra was 0.36 versus placebo,” and this number remained the same in adjusted analysis, the researchers wrote.

All five secondary endpoints on the WHO-CPS showed significant benefits of anakinra, compared with placebo. These included an absolute decrease of WHO-CPS at day 28 and day 14 from baseline; an absolute decrease of Sequential Organ Failure Assessment scores at day 7 from baseline; and a significantly shorter mean time to both hospital and ICU discharge (1 day and 4 days, respectively) with anakinra versus placebo.

Follow-up laboratory data showed a significant increase in absolute lymphocyte count at 7 days, a significant decrease in circulating IL-6 levels at 4 and 7 days, and significantly decreased plasma C-reactive protein (CRP) levels at 7 days.

Serious treatment-emergent adverse events were reported in 16% with anakinra and in 21.7% with placebo; the most common of these events were infections (8.4% with anakinra and 15.9% with placebo). The next most common serious treatment-emergent adverse events were ventilator-associated pneumonia, septic shock and multiple organ dysfunction, bloodstream infections, and pulmonary embolism. The most common nonserious treatment-emergent adverse events were an increase of liver function tests and hyperglycemia (similar in anakinra and placebo groups) and nonserious anemia (lower in the anakinra group).

The study findings were limited by several factors, including the lack of patients with critical COVID-19 disease and the challenge of application of suPAR in all hospital settings, the researchers noted. However, “the results validate the findings of the previous SAVE open-label phase 2 trial,” they said. The results suggest “that suPAR should be measured upon admission of all patients with COVID-19 who do not need oxygen or who need nasal or mask oxygen, and that, if suPAR levels are 6 ng/mL or higher, anakinra treatment might be a suitable therapy,” they concluded.

A large, real-world test of face masks in Bangladesh shows that masks work to reduce community spread of COVID-19. It also shows that surgical masks are more effective than cloth face coverings.

OsakaWayne Studios/Moment

The study, which was published ahead of peer review, demonstrates the power of careful investigation and offers a host of lessons about mask wearing that will be important worldwide. One key finding of the study, for example, is that wearing a mask doesn’t lead people to abandon social distancing, something public health officials had feared might happen if masks gave people a false sense of security.

“What we really were able to achieve is to demonstrate that masks are effective against COVID-19, even under a rigorous and systematic evaluation that was done in the throes of the pandemic,” said Ashley Styczynski, MD, who was an infectious disease fellow at Stanford (Calif.) University when she collaborated on the study with other colleagues at Stanford, Yale, and Innovations for Poverty Action, a large research and policy nonprofit organization that currently works in 22 countries.

“And so, I think people who have been holding out on wearing masks because [they] felt like there wasn’t enough evidence for it, we’re hoping this will really help bridge that gap for them,” she said.

It included more than 600 unions – or local governmental districts in Bangladesh – and roughly 340,000 people.

Half of the districts were given cloth or surgical face masks along with continual reminders to wear them properly; the other half were tracked with no intervention. Blood tests of people who developed symptoms during the study verified their infections.

Compared to villages that didn’t mask, those in which masks of any type were worn had about 9% fewer symptomatic cases of COVID-19. The finding was statistically significant and was unlikely to have occurred by chance alone.

“Somebody could read this study and say, ‘OK, you reduced COVID-19 by 9%. Big deal.’ And what I would respond to that would be that, if anything, we think that that is a substantial underestimate,” Dr. Styczynski said.

One reason they think they underestimated the effectiveness of masks is that they tested only people who were having symptoms, so people who had only very mild or asymptomatic infections were missed.

Another reason is that, among people who had symptoms, only one-third agreed to undergo a blood test. The effect may have been bigger had participation been universal.

Local transmission may have played a role, too. Rates of COVID-19 in Bangladesh were relatively low during the study. Most infections were caused by the B.1.1.7, or Alpha, variant.

Since then, Delta has taken over. Delta is thought to be more transmissible, and some studies have suggested that people infected with Delta shed more viral particles. Masks may be more effective when more virus is circulating.

The investigators also found important differences by age and by the type of mask. Villages in which surgical masks were worn had 11% fewer COVID-19 cases than villages in which masks were not worn. In villages in which cloth masks were worn, on the other hand, infections were reduced by only 5%.

The cloth masks were substantial. Each had three layers – two layers of fabric with an outer layer of polypropylene. On testing, the filtration efficiency of the cloth masks was only about 37%, compared with 95% for the three-layer surgical masks, which were also made of polypropylene.

Masks were most effective for older individuals. People aged 50-60 years who wore surgical masks were 23% less likely to test positive for COVID, compared with their peers who didn’t wear masks. For people older than 60, the reduction in risk was greater – 35%.
 

Rigorous research

The study took place over a period of 8 weeks in each district. The interventions were rolled out in waves, with the first starting in November 2020 and the last in January 2021.

Investigators gave each household free cloth or surgical face masks and showed families a video about proper mask wearing with promotional messages from the prime minister, a head imam, and a national cricket star. They also handed out free masks.

Previous studies have shown that people aren’t always truthful about wearing masks in public. In Kenya, for example, 88% of people answering a phone survey said that they wore masks regularly, but researchers determined that only 10% of them actually did so.

Investigators in the Bangladesh study didn’t just ask people if they’d worn masks, they stationed themselves in public markets, mosques, tea stalls, and on roads that were the main entrances to the villages and took notes.

They also tested various ways to educate people and to remind them to wear masks. They found that four factors were effective at promoting the wearing of masks, and they gave them an acronym – NORM.

• N for no-cost masks.
• O for offering information through the video and local leaders.
• R for regular reminders to people by investigators who stand in public markets and offer masks or encourage anyone who wasn’t wearing one or wasn’t wearing it correctly.
• M for modeling, in which local leaders, such as imams, wear masks and remind their followers to wear them.

These four measures tripled the wearing of masks in the intervention communities, from a baseline level of 13% to 42%. People continued to wear their masks properly for about 2 weeks after the study ended, indicating that they’d gotten used to wearing them.

Dr. Styczynski said that nothing else – not text message reminders, or signs posted in public places, or local incentives – moved the needle on mask wearing.
 

Saved lives and money

The study found that the strategy was cost effective, too. Giving masks to a large population and getting people to use them costs about $10,000 per life saved from COVID, on par with the cost of deploying mosquito nets to save people from malaria, Dr. Styczynski said.

“I think that what we’ve been able to show is that this is a really important tool to be used globally, especially as countries have delays in getting access to vaccines and rolling them out,” she said.

Dr. Styczynski said masks will continue to be important even in countries such as the United States, where vaccines aren’t stopping transmission 100% and there are still large portions of the population who are unvaccinated, such as children.

“If we want to reduce COVID-19 here, it’s really important that we consider the ongoing utility of masks, in addition to vaccines, and not really thinking of them as one or the other,” she said.

The study was funded by a grant from GiveWell.org. The funder had no role in the study design, interpretation, or the decision to publish.

“What we really were able to achieve is to demonstrate that masks are effective against COVID-19, even under a rigorous and systematic evaluation that was done in the throes of the pandemic,” said Ashley Styczynski, MD, who was an infectious disease fellow at Stanford (Calif.) University when she collaborated on the study with other colleagues at Stanford, Yale, and Innovations for Poverty Action, a large research and policy nonprofit organization that currently works in 22 countries.

“And so, I think people who have been holding out on wearing masks because [they] felt like there wasn’t enough evidence for it, we’re hoping this will really help bridge that gap for them,” she said.

It included more than 600 unions – or local governmental districts in Bangladesh – and roughly 340,000 people.

Half of the districts were given cloth or surgical face masks along with continual reminders to wear them properly; the other half were tracked with no intervention. Blood tests of people who developed symptoms during the study verified their infections.

Compared to villages that didn’t mask, those in which masks of any type were worn had about 9% fewer symptomatic cases of COVID-19. The finding was statistically significant and was unlikely to have occurred by chance alone.

“Somebody could read this study and say, ‘OK, you reduced COVID-19 by 9%. Big deal.’ And what I would respond to that would be that, if anything, we think that that is a substantial underestimate,” Dr. Styczynski said.

One reason they think they underestimated the effectiveness of masks is that they tested only people who were having symptoms, so people who had only very mild or asymptomatic infections were missed.

Another reason is that, among people who had symptoms, only one-third agreed to undergo a blood test. The effect may have been bigger had participation been universal.

Local transmission may have played a role, too. Rates of COVID-19 in Bangladesh were relatively low during the study. Most infections were caused by the B.1.1.7, or Alpha, variant.

Since then, Delta has taken over. Delta is thought to be more transmissible, and some studies have suggested that people infected with Delta shed more viral particles. Masks may be more effective when more virus is circulating.

The investigators also found important differences by age and by the type of mask. Villages in which surgical masks were worn had 11% fewer COVID-19 cases than villages in which masks were not worn. In villages in which cloth masks were worn, on the other hand, infections were reduced by only 5%.

The cloth masks were substantial. Each had three layers – two layers of fabric with an outer layer of polypropylene. On testing, the filtration efficiency of the cloth masks was only about 37%, compared with 95% for the three-layer surgical masks, which were also made of polypropylene.

Masks were most effective for older individuals. People aged 50-60 years who wore surgical masks were 23% less likely to test positive for COVID, compared with their peers who didn’t wear masks. For people older than 60, the reduction in risk was greater – 35%.
 

Rigorous research

The study took place over a period of 8 weeks in each district. The interventions were rolled out in waves, with the first starting in November 2020 and the last in January 2021.

Investigators gave each household free cloth or surgical face masks and showed families a video about proper mask wearing with promotional messages from the prime minister, a head imam, and a national cricket star. They also handed out free masks.

Previous studies have shown that people aren’t always truthful about wearing masks in public. In Kenya, for example, 88% of people answering a phone survey said that they wore masks regularly, but researchers determined that only 10% of them actually did so.

Investigators in the Bangladesh study didn’t just ask people if they’d worn masks, they stationed themselves in public markets, mosques, tea stalls, and on roads that were the main entrances to the villages and took notes.

They also tested various ways to educate people and to remind them to wear masks. They found that four factors were effective at promoting the wearing of masks, and they gave them an acronym – NORM.

• N for no-cost masks.
• O for offering information through the video and local leaders.
• R for regular reminders to people by investigators who stand in public markets and offer masks or encourage anyone who wasn’t wearing one or wasn’t wearing it correctly.
• M for modeling, in which local leaders, such as imams, wear masks and remind their followers to wear them.

These four measures tripled the wearing of masks in the intervention communities, from a baseline level of 13% to 42%. People continued to wear their masks properly for about 2 weeks after the study ended, indicating that they’d gotten used to wearing them.

Dr. Styczynski said that nothing else – not text message reminders, or signs posted in public places, or local incentives – moved the needle on mask wearing.
 

Saved lives and money

The study found that the strategy was cost effective, too. Giving masks to a large population and getting people to use them costs about $10,000 per life saved from COVID, on par with the cost of deploying mosquito nets to save people from malaria, Dr. Styczynski said.

“I think that what we’ve been able to show is that this is a really important tool to be used globally, especially as countries have delays in getting access to vaccines and rolling them out,” she said.

Dr. Styczynski said masks will continue to be important even in countries such as the United States, where vaccines aren’t stopping transmission 100% and there are still large portions of the population who are unvaccinated, such as children.

“If we want to reduce COVID-19 here, it’s really important that we consider the ongoing utility of masks, in addition to vaccines, and not really thinking of them as one or the other,” she said.

The study was funded by a grant from GiveWell.org. The funder had no role in the study design, interpretation, or the decision to publish.

Several health care-associated infections in U.S. hospitals spiked in 2020 compared to the previous year, according to a Centers for Disease Control and Prevention analysis published Sept. 2 in Infection Control and Hospital Epidemiology. Soaring hospitalization rates, sicker patients who required more frequent and intense care, and staffing and supply shortages caused by the COVID-19 pandemic are thought to have contributed to this increase.

This is the first increase in health care–associated infections since 2015.

These findings “are a reflection of the enormous stress that COVID has placed on our health care system,” Arjun Srinivasan, MD (Capt, USPHS), the associate director of the CDC’s Health care-Associated Infection Prevention Programs, Atlanta, told this news organization. He was not an author of the article, but he supervised the research. “We don’t want anyone to read this report and think that it represents a failure of the individual provider or a failure of health care providers in this country in their care of COVID patients,” he said. He noted that health care professionals have provided “tremendously good care to patients under extremely difficult circumstances.”

“People don’t fail – systems fail – and that’s what happened here,” he said. “Our systems that we need to have in place to prevent health care–associated infection simply were not as strong as they needed to be to survive this challenge.”

In the study, researchers used data reported to the National Healthcare Safety Network, the CDC’s tracking system for health care–associated infections. The team compared national standard infection ratios – calculated by dividing the number of reported infections by the number of predicted infections – between 2019 and 2020 for six routinely tracked events:

• Central line–associated bloodstream infections.
• Catheter-associated urinary tract infections (CAUTIs).
• Ventilator-associated events (VAEs).
• Infections associated with colon surgery and abdominal hysterectomy.
• Clostridioides difficile infections.
• Methicillin-resistant Staphylococcus aureus (MRSA) infections.

Infections were estimated using regression models created with baseline data from 2015.

“The new report highlights the need for health care facilities to strengthen their infection prevention programs and support them with adequate resources so that they can handle emerging threats to public health, while at the same time ensuring that gains made in combating HAIs [health care–associated infections] are not lost,” said the Association for Professionals in Infection Control and Epidemiology in a statement.

The analysis revealed significant national increases in central line–associated bloodstream infections, CAUTIs, VAEs, and MRSA infections in 2020 compared to 2019. Among all infection types, the greatest increase was in central-line infections, which were 46% to 47% higher in the third quarter and fourth quarter (Q4) of 2020 relative to the same periods the previous year. VAEs rose by 45%, MRSA infections increased by 34%, and CAUTIs increased by 19% in Q4 of 2020 compared to 2019.

The influx of sicker patients in hospitals throughout 2020 led to more frequent and longer use of medical devices such as catheters and ventilators. The use of these devices increases risk for infection, David P. Calfee, MD, chief medical epidemiologist at the New York–Presbyterian/Weill Cornell Medical Center, said in an interview. He is an editor of Infection Control and Hospital Epidemiology and was not involved with the study. Shortages in personal protective equipment and crowded intensive care units could also have affected how care was delivered, he said. These factors could have led to “reductions in the ability to provide some of the types of care that are needed to optimally reduce the risk of infection.”

There was either no change or decreases in infections associated with colon surgery or abdominal hysterectomy, likely because there were fewer elective surgeries performed, said Dr. Srinivasan. C. difficile–associated infections also decreased throughout 2020 compared to the previous year. Common practices to prevent the spread of COVID-19 in hospitals, such as environmental cleaning, use of personal protective equipment, and patient isolation, likely helped to curb the spread of C. difficile. Although these mitigating procedures do help protect against MRSA infection, many other factors, notably, the use of medical devices such as ventilators and catheters, can increase the risk for MRSA infection, Dr. Srinivasan added.

Although more research is needed to identify the reasons for these spikes in infection, the findings help quantify the scope of these increases across the United States, Dr. Calfee said. The data allow hospitals and health care professionals to “look back at what we did and then think forward in terms of what we can do different in the future,” he added, “so that these stresses to the system have less of an impact on how we are able to provide care.”

Dr. Srinivasan and Dr. Calfee report no relevant financial relationships.
