Researchers examined Institute for Clinical Evaluative Sciences (ICES) data that had been gathered from January 1, 2014, to December 31, 2021. The study focused on patients aged 18 years or older with confirmed primary cancer diagnoses.
Factors associated with an increased likelihood of an ED visit ahead of diagnosis included having certain cancers, living in rural areas, and having less access to primary care, according to study author Keerat Grewal, MD, an emergency physician and clinician scientist at the Schwartz/Reisman Emergency Medicine Institute at Sinai Health in Toronto, Ontario, Canada, and coauthors.
“The ED is a distressing environment for patients to receive a possible cancer diagnosis,” the authors wrote. “Moreover, it is frequently ill equipped to provide ongoing continuity of care, which can lead patients down a poorly defined diagnostic pathway before receiving a confirmed diagnosis based on tissue and a subsequent treatment plan.”
The findings were published online on November 4 in CMAJ).
Neurologic Cancers Prominent
In an interview, Grewal said in an interview that the study reflects her desire as an emergency room physician to understand why so many patients with cancer get the initial reports about their disease from clinicians whom they often have just met for the first time.
Among patients with an ED visit before cancer diagnosis, 51.4% were admitted to hospital from the most recent visit.
Compared with patients with a family physician on whom they could rely for routine care, those who had no outpatient visits (odds ratio [OR], 2.09) or fewer than three outpatient visits (OR, 1.41) in the 6-30 months before cancer diagnosis were more likely to have an ED visit before their cancer diagnosis.
Other factors associated with increased odds of ED use before cancer diagnosis included rurality (OR, 1.15), residence in northern Ontario (northeast region: OR, 1.14 and northwest region: OR, 1.27 vs Toronto region), and living in the most marginalized areas (material resource deprivation: OR, 1.37 and housing stability: OR, 1.09 vs least marginalized area).
The researchers also found that patients with certain cancers were more likely to have sought care in the ED. They compared these cancers with breast cancer, which is often detected through screening.
“Patients with neurologic cancers had extremely high odds of ED use before cancer diagnosis,” the authors wrote. “This is likely because of the emergent nature of presentation, with acute neurologic symptoms such as weakness, confusion, or seizures, which require urgent assessment.” On the other hand, pancreatic, liver, or thoracic cancer can trigger nonspecific symptoms that may be ignored until they reach a crisis level that prompts an ED visit.
The limitations of the study included its inability to identify cancer-related ED visits and its narrow focus on patients in Ontario, according to the researchers. But the use of the ICES databases also allowed researchers access to a broader pool of data than are available in many other cases.
The findings in the new paper echo those of previous research, the authors noted. Research in the United Kingdom found that 24%-31% of cancer diagnoses involved the ED. In addition, a study of people enrolled in the US Medicare program, which serves patients aged 65 years or older, found that 23% were seen in the ED in the 30 days before diagnosis.
‘Unpacking the Data’
The current findings also are consistent with those of an International Cancer Benchmarking Partnership study that was published in 2022 in The Lancet Oncology, said Erika Nicholson, MHS, vice president of cancer systems and innovation at the Canadian Partnership Against Cancer. The latter study analyzed cancer registration and linked hospital admissions data from 14 jurisdictions in Australia, Canada, Denmark, New Zealand, Norway, and the United Kingdom.
“We see similar trends in terms of people visiting EDs and being diagnosed through EDs internationally,” Nicholson said. “We’re working with partners to put in place different strategies to address the challenges” that this phenomenon presents in terms of improving screening and follow-up care.
“Cancer is not one disease, but many diseases,” she said. “They present differently. We’re focused on really unpacking the data and understanding them.”
All this research highlights the need for more services and personnel to address cancer, including people who are trained to help patients cope after getting concerning news through emergency care, she said.
“That means having a system that fully supports you and helps you navigate through that diagnostic process,” Nicholson said. Addressing the added challenges for patients who don’t have secure housing is a special need, she added.
This study was supported by the Canadian Institutes of Health Research (CIHR). Grewal reported receiving grants from CIHR and the Canadian Association of Emergency Physicians. Nicholson reported no relevant financial relationships.
