[Impact of a mobile geriatric psychiatry team on post-hospitalization emergency department consultations and rehospitalization].

Abstract

The objective of our work was to study the impact of a mobile health unit of geriatric psychiatry (EMGP) on the number of consultations to the emergency medical service and on the rate of readmissions. This was an observational, retrospective, single-center cohort study, which aimed to identify the number of visits to the Troyes SAU for psychiatric reasons. This in patients who have previously benefited from hospitalization in the Aube geriatric-psychiatry department called Ellipses. The "patients exposed" group was exposed by the existence of EMGP during hospitalization between January 1, 2018 and December 31, 2019. The group not exposed by the non-existence of the system between January 1, 2014 and December 31, 2015. Our results suggest that the actions implemented by the EMGP tend to reduce the frequency of visits to the emergency room after hospitalization, among people aged 65 and over (p<0.001) as well as their duration of hospitalization (p=0.003).
