The impact of COVID-19 on the health of physicians, nurses, and other health care workers [C19-HCW, study data contributed to the CITF Databank]

It also aimed to evaluate their mental health status and identify workplace practices and community supports that could be improved to increase safety and alleviate stress (Note: mental health data not shared with CITF Databank [1]).

Methods

Healthcare workers (physicians, nurses, health care aids, and personal support workers) across British Columbia, Alberta, Ontario, and Quebec were recruited into a cohort study via advertisements through professional organizations. Participants completed a screening interview and a baseline questionnaire. Participants who tested positive after their blood sample were placed into a nested cohort study.

At follow-up visits every 3 months, blood samples were collected, and exposure questionnaires and mental health assessments were administered. A blood sample was also collected 4 months post-vaccine. Contributed dataset contents: The datasets include 3005 participants who completed baseline questionnaires between April 2020 and November 2020. 87% of participants gave one or more blood samples for SARS-CoV-2 serology between September 2020 and June 2022 (in follow-up visits).

Variables include data in the following areas of information: demographics (age, gender, race-ethnicity and indigeneity, province, occupation), general health (smokes; asthma, lung disease, or immune compromised diagnosis; height and weight; flu vaccine), and longitudinal follow-up for COVID infections (dates of positive PCR or RAT tests, hospitalization, outcome and scale for impact of infection on everyday life), SARS-CoV-2 vaccination, and serology.
