CoMoNH - COvid19 MOrtality in Nursing Home

The Université Paris-Est Créteil together with INSERM (Institut National de la Santé et de la Recherche Médicale) formed the CoMoNH consortium (COvid19 MOrtality in Nursing Homes). The project’s main objectives were to estimate all causes of excess mortality among nursing home residents in France during the first wave of the COVID-19 epidemic (March 1-May 31 2020) by age bracket, sex, and département and to assess the possible existence of a “harvesting” effect (short-term mortality displacement) in the following months.

The study drew on RESID-EHPAD data [EHPAD: Etablissement d’Hébergement pour Personnes Agées Dépendantes, the French term for nursing home], a database managed by the French health system with information on all nursing homes and former long-term care units. That database is directly linked to the national health data system (SNDS), enabling researchers to determine residents’ vital status. The CoMoNH team compared observed mortality between March 1 and May 31, 2020 with expected mortality (i.e., identical for each age bracket and sex to average mortality for the previous six years, 2014-2019). This enabled them to estimate the number of excess deaths (observed minus expected deaths) and standardized mortality ratios (SMRs) over the period as whole and per week (up to August 31, 2020), then by age bracket, sex, and département. The first findings will be diffused soon.
