Abstract
OBJECTIVES: This study aimed to identify demographic, clinical and medical care factors associated with mortality in three nursing homes in France. METHODS: Two nursing homes were hospital-dependent, had connections with infection prevention and control departments, and had permanent physicians. A third nursing home had no direct connection with a general hospital, no infection control practitioner, and no permanent physician. The main outcome was death. RESULTS: During the first 3 months of the outbreak, 224 of 375 (59.7%) residents were classified as COVID-19 cases and 57 of 375 (15.2%) died. The hospital-dependent nursing homes had lower COVID-19 case fatality rates in comparison with the non-hospital-dependent nursing home (15 [6.6%] vs 38 [25.8%], OR 0.20 [0.11-0.38], p = 0.001). During the first 3 weeks of the outbreak, mortality in COVID-19 patients decreased if they had a daily clinical examination (OR: 0.09 [0.03-0.35], p = 0.01), three vital signs measurement per day (OR: 0.06 [0.01-0.30], p = 0.001) and prophylactic anticoagulation (OR: 0 [0.00-0.24], p = 0.001). CONCLUSIONS: This study suggested that high mortality rates in some nursing homes during the COVID-19 outbreak might have been contributed by a lack of medical care management. Increasing human and material resources, encouraging presence of nursing home physicians and establishing a connection with general hospitals should be considered to deal with present and future health disasters in nursing homes.
