Abstract
in English, Spanish

Background: Although healthcare personnel are considered a high-risk group for SARS-CoV-2 infection due to their exposure, research on the factors associated with their infection is limited. The objective was to identify factors associated with the acquisition of COVID-19 in healthcare personnel.

Methods: a multicenter, cross-sectional study with nested cases and controls was carried out in 23 hospitals in Argentina. A structured survey was used to collect demographic, institutional and behavioral variables from healthcare personnel with positive RT-PCR for SARS-CoV2 (cases) and healthcare personnel with negative test results (controls). Those variables significantly associated with the condition of having had COVID-19 in the bivariate analysis were included in a multivariate analysis.

Results: A total of 2088 workers participated in the study, with an incidence of 1.41 cases per 10 000 worker-hours (95%CI 1.35-1.48). Being male, (OR 1.60; 95%CI 1.32-1.95), working in social security, (OR 1.53; 95%CI 1.13-2.07), being nursing staff, (OR 1.46; 95%CI 1.22-1.74), having personal protective equipment, (OR 0.33; 95%CI 0.18-0.62), sharing unprotected common spaces with other workers, (OR 1.98; 95%CI 1. 60-2.44), living with people confirmed or suspected of COVID-19 (OR 1.69; 95%CI 1.37-2.09), sharing infusions or other drinks and/or food with people in the community (OR 1.31; 95%CI 1.02-1.70), feeling distressed (OR 1.85; 95%CI 1.55-2.21) and were independently associated with the risk of acquiring COVID-19.

Discussion: This study allowed us to identify different potentially modifiable factors on which action should be taken to reduce the risk of acquiring COVID-19 by the healthcare personnel.

Introducción: Aunque, el personal sanitario es considerado por su exposición un grupo de alto riesgo de infección por SARS-CoV-2, la investigación sobre los factores asociados a infección resulta limitada. El objetivo fue identificar los factores asociados a la adquisición de COVID-19 en el personal sanitario. Materiales y métodos: Estudio multicéntrico, de corte transversal con casos y controles anidados, en 23 hospitales de Argentina. A través de una encuesta estructurada se recolectaron variables demográficas, institucionales y conductuales del personal sanitario con RT-PCR positiva para SARS-CoV-2 (casos) y del personal sanitario con resultados negativos en el test (controles). Aquellas variables asociadas significativamente con la condición de haber padecido COVID-19 en el análisis bivariado fueron incluidas en un análisis multivariado. Resultados: Participaron del estudio 2088 trabajadores, con una incidencia de 1.41 casos c/10 000 horas-trabajador (IC95% 1.35-1.48). Pertenecer al sexo masculino (OR 1.60; IC95% 1.32-1.95), trabajar en la seguridad social (OR 1.53; IC95% 1.13-2.07), ser personal de enfermería (OR 1.46; IC95% 1.22-1.74), contar con elementos de protección personal (OR 0.33; IC95% 0.18-0.62), compartir con otros trabajadores espacios comunes sin protección (OR 1.98; IC95% 1.60-2.44), convivir con personas confirmadas o sospechadas de COVID-19 (OR 1.69; IC95% 1.37-2.09), compartir infusiones u otras bebidas y/o alimentos con personas de la comunidad (OR 1.31; IC95% 1.02-1.70), sentirse angustiado (OR 1.85; IC95% 1.55-2.21) se asociaron independientemente con el riesgo de adquirir COVID-19. Discusión: Este estudio permitió identificar distintos factores potencialmente modificables, sobre los cuales se debería actuar para reducir el riesgo de COVID-19 en el personal sanitario.
