Clinical characteristics and risk factors for mortality in 1048 Health care workers hospitalised with COVID 19 in a Tertiary care hospital, India

ABSTRACT

Objectives: We aim to study the clinical characteristics and risk factors for mortality of doctors and nurses hospitalized with COVID-19. Materials and Methods: This was a hospital-based cross-sectional study. All doctors and nurses positive on reverse transcriptase-polymerase chain reaction test of nasopharyngeal or/and oropharyngeal samples for COVID-19 who were admitted in this designated COVID hospital from April 2020 to January 2021 and with a definite outcome (death or discharge) till the end of January 2021 were included in this study. To explore the risk factors associated with mortality of health-care workers (HCWs), bivariate and multivariate logistic regression analysis was done. Results: Out of 1048 HCWs, 846 (80.7%) were doctors and 202 (19.3%) were nurses. Majority (619, 59.15%) of the HCWs were young (18-30 years). Most (185, 91.6%) of the nurses were female, while majority (533, 63%) of the doctors were male. The 11 (1%) HCWs who died were all doctors, but the difference was not statistically significant. Total 121 (11.54%) HCWs had comorbidities, and hypertension 70 (6.7%) and diabetes 62 (5.9%) were most common. Age > 60 years (adjusted odds ratios [AOR] [confidence interval (CI)] = 36.01 [3.45-375.5]) and suffering from diabetes mellitus (AOR [CI] = 10.4 [1.82-59.51]) were found to be significant predictors for the death of HCWs after adjusting for potential confounders. Conclusion: The mortality rate due to COVID-19 in doctors and nurses was lower (1%) as compared to the general population as most of the HCWs were young and with a low prevalence of comorbidities. Age > 60 years and diabetes mellitus were risk factors for death;such HCWs should avoid contact with COVID-19 patients. Screening of HCWs for COVID-19 is important to reduce its transmission.
