Primary care physicians who served marginalized communities had the highest proportion of patients who were unvaccinated against COVID-19, Canadian data suggested.
A study of more than 9000 family physicians in Ontario also found that the physicians with the largest proportion of unvaccinated patients were more likely to be male, to have trained outside Canada, to be older, and to work in an enhanced fee-for-service model than their counterparts who had lower proportions of unvaccinated patients.
“The family physicians with the most unvaccinated patients were also more likely to be solo practitioners and less likely to practice in team-based models, meaning they may have fewer support staff in their clinics,” lead author Jennifer Shuldiner, PhD, a scientist at Women’s College Hospital in Toronto, Ontario, Canada, told this news organization.
The findings were published in CMAJ.
Need vs Resources
Dr. Shuldiner and her team had been working on a project to provide additional support to family physicians with large numbers of patients who had not received their COVID-19 vaccinations. Their goal was to encourage family physicians to support these patients in getting vaccinated.
“As we were designing this project, we wondered how these physicians and their patients might differ. What characteristics might they have that would enable us to design and implement an intervention with high uptake and impact?” she said.
The researchers conducted a cross-sectional, population-based cohort study using linked administrative datasets in Ontario. They calculated the percentage of patients unvaccinated against SARS-CoV-2 who were enrolled with each comprehensive care family physician, ranked physicians according to the proportion of unvaccinated patients, and identified 906 physicians in the top 10% of unvaccinated patients. These physicians were compared with the remaining 90% of family physicians.
The physicians with the highest proportion of unvaccinated patients cared for 259,130 unvaccinated patients as of November 1, 2021. The proportion of patients who received two or more doses of the SARS-CoV-2 vaccine in this group was 74.2%. In comparison, the proportion of patients who received two or more doses of the vaccine was 87.0% in the remaining 90% of physicians.
Physicians with the largest proportion of unvaccinated patients were more likely to be male (64.6% vs 48.1%), to have trained outside Canada (46.9% vs 29.3%), to be older (mean age, 56 years vs 49 years), and to work in an enhanced fee-for-service model (49% vs 28%).
The study also found that patients enrolled with physicians in the most unvaccinated group tended to live in places with more ethnic diversity, higher material deprivation, and lower incomes. The proportion of recent immigrants was higher in this group.
“Clinics or practices with a large number of unvaccinated patients could be viable targets for efforts to coordinate public health and primary care,” said Dr. Shuldiner.
The findings indicate “the ongoing inverse relationship between the need for care and its accessibility and utilization. In other words, the practices with the highest need receive the fewest resources,” she noted.
“We know that relationships with trusted family physicians can positively influence patients’ decisions. Our study highlights the need to create equitable systems and processes that create opportunities for primary care teams to play a crucial role in influencing general and COVID-19-specific vaccine-related decision-making.”
