Background: The aim of this study was to retrospectively describe the evolution of symptoms, infections,
and mortality at a nursing facility in France that had implemented a protocol for the prevention and
treatment of COVID-19.
Methods: A database was created on 21 March 2020 to store all information related to residents, including
co-morbidities, as well as COVID-19 symptoms, incidence, and mortality. Residents followed a COVID-19
protocol, consisting of preventive (administering vitamins and zinc, social distancing, and temperature
checks) and active (antibiotics, anticoagulants, and corticosteroids) measures. RT-PCR and serology testing
were performed on residents. A new coefficient, named the Zemgor coefficient, was calculated as the
haemoglobin-to-albumin ratio at 2 time points 15 days apart, to monitor hypoxemia.
Results: In January 2020, the nursing facility housed 192 residents, 75 men and 117 women, aged 80±11.
One or more co-morbidities were present in 94% of residents, with the most common being dementia. The
COVID-19 protocol provided 61% of residents with anticoagulants, 51%with antibiotics, 21% with oxygen
therapy, and 3% with corticosteroids. The COVID-19 incidence was 51% based on presence of COVID-19
symptoms, 35% based on positive RT-PCR (amongst residents tested for RT-PCR) and 41% based on
positive serology (amongst residents tested for serology), and the COVID-19 mortality rate was 8%. The
Zemgor coefficient was 0.049±0.053 for patients with hypoxemia compared to 0.011±0.041 for patients
without hypoxemia (P=0.001).
Conclusions: The protocol for the prevention and treatment of COVID-19 implemented at this nursing
facility resulted in a COVID-19 incidence and mortality at the lower end of that reported by other nursing
facilities.
