Resumen
MOLLOV, Asan et al. Global view of the SARS-COV-2 pandemic in the working population of the Navarran Health Service-Osasunbidea. Rev Asoc Esp Espec Med Trab [online]. 2023, vol.32, n.2, pp.117-130. Epub 30-Oct-2023. ISSN 3020-1160.
Objectives:
The pandemic caused by the biological agent SARS-CoV-2 had a great impact among the working population in the health field. This study aims to describe the most relevant events experienced by the professionals of the Navarro Health Service-Osasunbidea, related to infections, reinfections, vaccination and professional contingencies, throughout the pandemic waves.
Material and Methods:
Descriptive cross-sectional study that encompasses the period between March 4, 2020 to September 30, 2022. The data was obtained from the computer application for registration and monitoring of cases RASTREA® and of the Population Vaccine Registry INMUNIS®. The results were grouped and presented according to age range and job position. The vaccination impact and professional contingencies were estimated using statistical models.
Results:
The total number of infections studied was 9,692: 88.17% professionals suffered a single infection; 11.32% were reinfected for the second time and only 0.49% professionals registered three infections. The impact of the vaccination intervention was significant during the fourth and fifth pandemic waves and decreased after the sixth. 99.5% (0.97-1.01) fourth, 97.3% (0.95-0.99) fifth, dropping to 72.8% (0.71-0.74) during the sixth and 81.6% (0.79-0.83) and 84.7% (0.83-0.86) during the sixth A and B respectively (direct effectiveness with 95%CI).
Conclusions:
The sixth wave of the pandemic had a great impact on health workers. The professionals with greater proximity in patient care experienced a higher rate of infections and reinfections of doctors and nurses. Age was a variable associated with a higher prevalence of infection in younger age groups. The highest number of infections and reinfections corresponded to hospital setting. Due to the vaccination intervention, almost no fourth wave was observed in the healthcare workplace.
