Brief Summary

Context. Sleep disorders complaints are common in elderly and hypnosedative drugs are widely prescribed in community-dwelling elderly. Furthermore, acute hospitalisation may induce sleep disorders and hypnosedative initiation occurs in 14 to 29% of elderly during a hospital stay. These hospital-induced sleep disorders should spontaneously disappear after discharge and, because of their potential impact on falls, hip fractures, psychiatric side effects and induced dependence, hypnosedative drugs should therefore be discontinued at discharge in these naïve-treated patients. Adhesion to this recommendation is poor. Recent and on-going research on this topic mostly concerns adverse effects although these are already substantially documented and evidence-based, while there is a poor interest on developing research on potential strategies susceptible to practically improve the current adhesion to recommendations.

Design and objectives. This project proposes multi-component intervention and is directed towards hospital prescribers, patients, and their general practitioner. It aims at discontinuing, at hospital discharge, the hypnosedative treatment that was initiated during hospitalization in naïve-treated elderly (age≥65) patients. The value of the intervention, as compared to usual care management, will be estimated in a multicentre (6 hospitals gathering 8 centres: 5 internal medicine departments, 3 cardiology departments) randomised, cross-over, two-period trial. Two hospitals will gather 2 centres (2x2 centres) and 4 hospitals will gather only 1 centre (4x1 centres). An equilibrated randomization will be applied to the 8 centres, making sure that, in hospitals gathering 2 centres, these 2 centres will apply the same strategy in a given period and that the 2 hospitals will apply alternative strategies. This randomisation is set up to avoid the risk of a potential contamination between the 2 strategies from one centre to the other within the same hospital. As a result, 3 hospitals (including 4 medical departments) will apply the intervention during the first 6-month period, while the 3 others (including 4 medical departments) will apply usual care during this period, as a result of an equilibrated hospitals randomization. During the second 6-month period, each hospital will apply the alternative management. The two periods will be separated by a 6-month wash-out period.

In all 240 patients (15 patients / centre) will be enrolled (120 in the intervention group and 120 in the usual care group).

Patient follow-up duration will be 12 months after discharge. Patient status in regards with quality of sleep (study primary objective), hypnosedative consumption and frequency of falls (secondary objectives) will be collected by telephone interviews 1, 3, 6 12 months after discharge.

Expected results. The results of the study should contribute to guide research and public decisions to practically decrease hypnosedative prescription and consumption, and associated adverse events.
