Adherence to non-pharmacological preventive measures among healthcare workers in a middle-income country during the first year of the COVID-19 pandemic: Hospital and community setting.

This study assessed, using a self-reported questionnaire, the adherence to PPE (mask, gowns, and gloves) at the workplace, as well as to non-pharmacological preventive measures (NPPM) (physical distance defined as hardly ever and/or never approaches other people within 1.5 meters, social isolation as leaving home less than once a week, hand hygiene was defined as performing hand hygiene ≥ 6 times per period, and adherence to the use of a mask outside of the workplace was defined as on all outings and hardly ever and/or never removes the mask) outside of the workplace among 1,296 health care workers (HCWs), including if NPPM adherence was associated with COVID-19 in HCWs. High adherence to PPE was independently associated with younger age, professional category, work in an area of direct patient assistance; use of public transportation, or adherence to NPPM outside of the workplace.
