Impact immédiat d’une infection liée à la Covid-19 et du confinement consécutif sur les résidents d’un Ehpad

Introduction: Following the Covid-19 epidemic affecting 76 of the 97 residents (78.3 %) in a French nursing home, we assessed the impact of this cluster period on the physical and psycho-cognitive health of the residents, expecting in particular to observe effects that were dependent on their state of cognitive-behavioural dependence. Methods: We retained twenty-two variables, 5 relating to demographic data, 6 to the specific care linked to Covid-19 infection, 6 to somatic pathologies and psycho-behavioural disturbances before the epidemic and 5 to the period following it. Results: Eleven residents among those diagnosed positive died. Nine were transferred to a Covid unit, and 35 were asymptomatic. The main consequences of the period of infections were in particular behavioural, nutritional, and motor. A history of disruptive behaviours before the appearance of the cluster increased the risk of an aggravation of these behaviours by four (RR = 3.9, IC95 % = 1.38–11.02, p = 0.0042). Twenty per cent of the residents presented under-nutrition at the end of lockdown, but no specific risk factors could be identified. However, states of under-nutrition for the whole of 2020 were significantly more frequent than in 2019, in particular severe cases (χ² = 5.43, p = 0.02). A history of under-nutrition in the previous year increased twofold the likelihood of under-nutrition in the following year (RR = 2.07, IC95 % = 1.14–3.74, p = 0.02). The Covid cluster period also had an effect on the functional autonomy of certain patients. Conclusion: Our main hypothesis relating to cognitive-behavioural dependence was not completely validated. The impact of the occurrence of the cluster remained moderate, in particular because of the care resources afforded by the nursing home. The advantages of a “medicalised” facility, and the problems associated with the restrictions of lockdown, are viewed in the light of ethical considerations. Introduction : Suite à une épidémie de Covid-19 ayant affecté 76 des 97 résidents d’un Ehpad, nous avons évalué l’impact de cette période de cluster sur la santé physique et psycho-cognitive des résidents pronostiquant notamment une altération en fonction de leur dépendance cognitivo-comportementale. Méthodes : Nous avons retenus vingt-deux variables relatives : aux données démographiques (5) ; aux prises en charge spécifiques liées à l’infection (6) ; aux pathologies somatiques et troubles psycho-comportementaux avant l’épidémie (6) et après la péri
