Antibiotic prescribing in pediatric primary care decreased dramatically when the COVID-19 pandemic hit, and new research indicates that drop was sustained through June of 2021.

Lauren Dutcher, MD, with the division of infectious diseases at Hospital of the University of Pennsylvania in Philadelphia, led a study of 27 pediatric primary care practices in the United States. Encounters from Jan. 1, 2018, through June 30, 2021, were included.

Researchers found a 72.7% drop in antibiotic prescriptions when they compared prepandemic April 2019 through December 2019 with the same period in 2020.

Prescriptions remained at the lower levels, primarily driven by reductions in respiratory tract infection (RTI) encounters, and began to rise only in April of 2021, the authors write.

Findings were published online Jan. 11 in Pediatrics.

Researchers report there were 69,327 antibiotic prescriptions from April through December in 2019 and 18,935 antibiotic prescriptions during the same months in 2020.

“The reduction in prescriptions at visits for respiratory tract infection (RTI) accounted for 87.3% of this decrease,” the authors write.

Both prescribing and acute non–COVID-19 respiratory tract infection diagnoses decreased.

Researchers conclude reductions in viral RTI transmission likely played a large role in reduced RTI pediatric visits and antibiotic prescriptions.

Dr. Dutcher told this publication the reduction was likely caused by a combination of less viral transmission of respiratory infections, helped in part by masking and distancing, but also avoidance of health care in the pandemic.

She said the data reinforce the need for appropriate prescribing.

“Antibiotic prescribing is really heavily driven by respiratory infections so this should continue to clue providers in on how frequently that can be unnecessary,“ she said.

Dr. Dutcher said there was probably a reduction in secondary bacterial infections as well as the viral infections.

The research is more comprehensive than some other previous studies, the authors write.

“Although other studies demonstrated early reductions in RTIs and antibiotic prescribing during the COVID-19 pandemic, to our knowledge, this is the first study to demonstrate a sustained decrease in antibiotic prescribing in pediatric primary care throughout 2020 and early 2021,” they write.

The findings also suggest benefits of preventive measures during the pandemic, the authors say.

“Our data suggest that reducing community viral RTI transmission through social distancing and masking corresponds with a reduction in antibiotic prescribing,” they write.

Kao-Ping Chua, MD, a pediatrician and an assistant professor of pediatrics at the University of Michigan in Ann Arbor, said the reductions indicate one of two things is happening: either children aren’t getting sick as often during the pandemic or they are getting sick, but not coming in.

Key clinical point: Ubrogepant was effective and safe in patients with migraine, regardless of prior or concomitant preventive medication use.

Major finding: Ubrogepant vs. placebo was associated with significantly higher responder rates for pain freedom (P £ .005), absence of most bothersome symptom (50 mg ubrogepant vs. placebo; P £ .001), and pain relief (P £ .011) at 2 hours, with the responder rates not being significantly different among patients with vs. without preventive medication use (all P > .05). No serious or treatment-related adverse events were reported.

Study details: Findings are from a pooled analysis of ACHIEVE I and ACHIEVE II phase 3 trials (n = 2,247) and the long-term safety extension trial (n = 813) including patients with migraine with or without a history of preventive medication use.

Disclosures: This study was funded by Allergan (before its acquisition by AbbVie). Some investigators, including the lead author, reported advising or consulting for; being a speaker, on the board of directors, or a contributing author for; receiving grants, research support, and honoraria from; holding stocks or patents with; or employment with various sources including Allergan and AbbVie.

Key clinical point: Fremanezumab was effective and well tolerated over 12 weeks in older patients with chronic or episodic migraine.

Major finding: Quarterly and monthly fremanezumab vs. placebo showed greater reduction in monthly average migraine days (least-squares mean change from baseline [D] −4.3 and −4.6 vs. −2.3), headache days of at least moderate severity (D −3.9 and −4.2 vs. −2.1), and acute medication use (D −3.7 and −4.0 vs. −1.3) over 12 weeks (all P < .05). Adverse events were similar across groups.

Study details: Findings are pooled subgroup analysis of 3 phase 3 studies (HALO CM, HALO EM, and FOCUS) including 246 participants aged ≥60 years with chronic or episodic migraine with an inadequate response to 2-4 prior migraine preventives. They were randomly assigned to quarterly fremanezumab, monthly fremanezumab, or matched monthly placebo.

Key clinical point: Unilateral pain, fewer failed preventives, good response to triptans, and medication overuse at baseline were associated with a persistent positive response to galcanezumab during the first 3 months of therapy in patients with chronic migraine.

Major finding: Overall, 41.7% of patients had a persistent 3-month 50% responder rate in headache days of at least moderate intensity. Responders vs. nonresponders had lower number of failed preventives (odds ratio [OR] 0.733; P = .041), frequent unilateral pain (OR 3.686; P = .041), medication overuse at baseline (OR 4.575; P = .012), and good response to triptans (OR 3.248; P = .028).

Key clinical point: Lasmiditan was associated with mild-to-moderate central nervous system (CNS)-related adverse events (AE), mostly transient in duration.

Major finding: Treatment-emergent serious AEs occurred in 0.4%, 0.2%, and 0.4% of patients treated with placebo, 100 mg lasmiditan, and 200 mg lasmiditan, respectively. The most common treatment-emergent AEs with lasmiditan were dizziness, nausea, paresthesia, fatigue, somnolence, and vertigo, with mostly mild-to-moderate severity. No deaths were reported.

Study details: Findings are from safety analysis of the phase 3 CENTURION trial that assessed 4,494 attacks across 1,471 patients with migraine with and without aura who were randomly assigned to either 200 mg lasmiditan or 100 mg lasmiditan for 4 attacks or placebo for 3 attacks and 50 mg lasmiditan for the third/fourth attack.

Disclosures: This study was sponsored by Eli Lilly and Company.

Key clinical point: Greater occipital nerve (GON) blockade with local anesthetics reduced the severity and duration of headaches in patients with episodic migraine without aura, with the headache frequency reducing significantly among patients receiving lidocaine alone or in combination with triamcinolone.

Major finding: GON block with triamcinolone, lidocaine, lidocaine+triamcinolone, or only normal saline significantly reduced the severity (P < .001) and duration (P = .001) of headaches, with no injection being superior to placebo. Headache frequency reduced in patients who received lidocaine (5.81 attacks per month; 95% CI of the difference −2.52 to −9.09) and lidocaine+triamcinolone (5.69 attacks per month; 95% CI of the difference −1.11 to −10.27).

Study details: This placebo-controlled clinical trial randomly assigned 55 adult patients with episodic migraine without aura to triamcinolone (n = 10), lidocaine (n = 16), lidocaine+triamcinolone (n = 13), or normal saline only (n = 16) groups.

Key clinical point: Greater occipital nerve (GON) blockade with local anesthetics reduced the severity and duration of headaches in patients with episodic migraine without aura, with the headache frequency reducing significantly among patients receiving lidocaine alone or in combination with triamcinolone.

Key clinical point: Intranasal ketorolac was not inferior to intravenous ketorolac in reducing pain intensity 60 min postmedication in children with migraine headaches of moderate-to-severe pain intensity.

Major finding: The difference in mean pain reduction at 60 min between intranasal and intravenous ketorolac groups was 0.2 (95% CI −0.9 to 1.3), with intranasal ketorolac being noninferior to intravenous ketorolac (P < .001). No serious adverse events were reported.

Study details: Findings are from a phase 3 clinical trial including 59 children (age 8-17 years) with migraine headache of moderate-to-severe pain intensity requiring any intravenous analgesic. They were randomly assigned to receive either intranasal ketorolac (1 mg/kg) or intravenous ketorolac (0.5 mg/kg).
