The COVID-19 Impact in hospital healthcare workers: development of an occupational health risk management program.

Abstract As with the SARS-CoV-1 outbreak in 2003-2004 and the MERS outbreak in 2012, there were early reports of frequent transmission to healthcare workers (HCW) in the SARS-CoV-2 pandemic. Our hospital center identified its first COVID-19 confirmed case on March 9, 2020, in a 6-day hospitalized patient. The first confirmed COVID-19 case in a HCW happened 3 days later, in a nurse with a probable epidemiological link related to the first confirmed patient. Our study’s first objective is to describe and characterize the impact of the first 3 months of the SARS-CoV-2 pandemic on the Centro Hospitalar Universitário Lisboa Norte (CHULN). Our second objective is to report the performance of the CHULN Occupational Health Department (OHD) and the impact of the pandemic on CHULN HCW and its adaptation across national, regional, and institutional epidemiological evolution. Over the first 3 months, 2,152 HCW were screened (which represent 29.8% of the total HCW population), grouped in 100 separate identifiable clusters, each one ranging from 2 to 98 HCW. The most prevalent profession screened were nurses (n = 800; 37.2%) followed by doctors (n = 634; 29.5%). The main source of potential infection and cluster generating screening procedures was co-worker related (n = 1,216; 56.5%). A patient source or a combined patient co-worker source was only accountable for 559 (26%) and 43 (2%) of cases, respectively. Our preliminary results demonstrate a lower infection rate among HCW than the ones commonly found in the literature. The main source of infection seemed to be co-worker related rather than patient related. New preventive strategies would have to be implemented in order to control SARS-CoV-2 spread.
