The prevalence, determinants, and consequences of post‐COVID in healthcare workers: A cross‐sectional survey

Abstract

AbstractData on post‐coronavirus disease (COVID) in healthcare workers (HCWs) are scarce. We aimed to assess prevalence, determinants, and consequences of post‐COVID in HCWs. In fall 2022, we performed a cross‐sectional survey in a tertiary care hospital with a web‐based questionnaire sent to HCWs. Post‐COVID was defined as persistent/new symptoms 3 months after acute COVID. Propensity score weighting was performed to assess the impact of post‐COVID on return‐to‐work. 1062 HCWs completed the questionnaire, 713 (68%) reported at least one COVID, and 109 (10%) met the definition for post‐COVID, with workplace contamination reported in 51 (47%). On multivariable analysis, risk factors for post‐COVID were female gender (p = 0.047), ≥50 years (p = 0.007), immunosuppression (p = 0.004), ≥2 COVID episodes (p = 0.003), and ≥5 symptoms during acute COVID (p = 0.005). Initial sick leave was prescribed for 94 HCWs (86% post‐COVID), for a median duration of 7 [7–9] days, and extended for 23. On return‐to‐work, 91 (84%) had residual symptoms, primarily asthenia/fatigue (72%) and cognitive impairment (25%). Cognitive impairment at return‐to‐work was associated with post‐COVID. Ten HCWs (9%) received a medical diagnosis of post‐COVID, 8 consulted the occupational physician, and four required work adaptation. Post‐COVID affected 10% of HCWs. Long‐term consequences included repeated sick leaves and residual symptoms on return‐to‐work.
