Resumen
Introducción: la pandemia por COVID-19 es uno de los principales problemas de salud pública en el mundo. De las personas contagiadas, una gran cantidad son trabajadores de la salud de unidades de primer nivel.
Objetivo: determinar la relación entre el tiempo de estancia en consultorios respiratorios y la infección de SARS-CoV-2 en trabajadores de la salud de un centro de primer nivel de atención.
Material y métodos: estudio transversal analítico en trabajadores de primer nivel de atención de San Luis Potosí, México, que desarrollaron síntomas de COVID-19 de marzo de 2020 a enero de 2021. Se les realizó RT-PCR para SARS-CoV-2 y a partir del resultado se conformaron dos grupos. Se registraron variables demográficas, ocupación, área de trabajo, trabajo en consultorio respiratorio, horas de trabajo acumuladas en consultorio respiratorio/toma de muestra hasta el desarrollo de síntomas, fecha de desarrollo de síntomas.
Resultados: de 350 trabajadores, 144 desarrollaron sintomatología respiratoria; de estos, 66 tuvieron RT-PCR positiva para SARS-CoV-2. Atender pacientes en un consultorio no respiratorio confiere una RM 2.49 (1.04-6.26) con respecto a los que trabajan en consultorio respiratorio para infección por SARS-CoV-2 (p 0.0446). Estar en filtro respiratorio confiere una RM protectora de 0.3062 (0.08-0.99) de infección por SARS-CoV-2 (p 0.0608). Cada hora acumulada en un consultorio respiratorio confiere una RM 1.001 (0.99-1.00) sin significación estadística (p 0.3046).
Conclusión: trabajar en consultorio respiratorio y las horas acumuladas de trabajo en este no son factores de riesgo para desarrollar COVID-19 en los trabajadores de la salud.
Abstract
Background: The pandemic caused by COVID-19 is one of the main problems of public health around the world. Of the individuals with infection, a large amount corresponds to first-level health workers.
Objective: To determine the relationship between length of stay in respiratory offices and SARS-CoV-2 infection in health workers at a first-level health center.
Material and methods: Cross-sectional analytic study in health workers of a first-level unit of San Luis Potosí, Mexico, who developed suspected symptomatology of SARS-CoV-2 infection from March 2020 to January 2021. Two groups were formed according to the result of the RT-PCR. Demographic variables, occupation, work area, work in respiratory area, hours of work accumulated within the respiratory area to develop symptomatology, and date of development of symptomatology were registered.
Results: Of 350 health workers active, 144 developed respiratory symptomatology; of these, 66 had positive RT-PCR for SARS-CoV-2 infection. Working in an area with no respiratory patients but in contact with other patients confers an OR 2.49 (1.04-6.26), when compared with working in a respiratory area, p 0.0446. The length in a filter for respiratory patients gives a protective OR of 0.3062 (0.08-0.99) for developing SARS-CoV-2 infection, p 0.0608. Each hour accumulated in a respiratory area confers an OR 1.001 (0.99-1.00) without statistical significance, p 0.3046.
Conclusion: Working in a respiratory area and the accumulated hours of work in this place are not risk factors for developing COVID-19 in health workers.
