Sažetak
Aim To assess this risk of SARS-CoV-2 infection among Ontario physicians by specialty and in comparison with nonphysician controls during the COVID-19 pandemic.
Methods In this retrospective cohort study, the primary
outcome was incident SARS-CoV-2 infection confirmed
by polymerase chain reaction (PCR). Secondary outcomes
were hospitalization, use of critical care, and mortality.
Results From March 1, 2020 to December 31, 2022,
6172/30 617 (20%) active Ontario physicians tested positive for SARS-CoV-2. Infection was less likely if physicians
were older (OR 0.78 [0.76-0.81] per 10 years), rural residents
(OR 0.70 [0.59-0.83]), and lived in more marginalized neighborhoods (OR 0.74 [0.62-0.89]), but more likely if they were
female (OR 1.14 [1.07-1.22]), worked in long-term care settings (OR 1.16 [1.02-1.32]), had higher patient volumes (OR
2.05 [1.82-2.30] for highest vs lowest), and were pediatricians (OR 1.25 [1.09-1.44]). Compared with communitymatched controls (n=29 763), physicians had a higher risk
of infection during the first two waves of the pandemic
(OR 1.38 [1.20-1.59]) but by wave 3 the risk was no longer significantly different (OR 0.93 [0.83-1.05]). Physicians
were less likely to be hospitalized within 14 days of their
first positive PCR test than non-physicians (P<0.0001), but
there was no difference in the use of critical care (P=0.48)
or mortality (P=0.15).
Conclusion Physicians had higher rates of infection than
community-matched controls during the first two waves
of the pandemic in Ontario, but not from wave 3 onward.
Physicians practicing in long-term care facilities and pediatricians were more likely to test positive for SARS-CoV-2
than other physicians.
