To reduce the frequency of readmissions in a population of geriatric patients (≥75 years) admitted to an emergency department.

The study was quasi-RCT. Consecutive admission days were randomised to intervention or control. Admitted eligible patients belonged to the assigned day's strategy. Intervention comprised a geriatrician and nurse home visit on the day following hospital discharge. Control patients underwent our standard procedure, including follow-home by a carer or a telephone call the next day.

1330 patients were included. Intervention group readmissions were significantly reduced compared to controls (12% vs. 23%; P<0.001). The intervention group adjusted hazard ratio was 0.50 (95% CI: 0.38–0.65; P<0.001). Total hospitalisation was shorter for the intervention group: median (IQR): 2 (1–7) vs. 3 (1–8) days; P=0.03. No group mortality difference was statistically significant (intervention 12% vs. 14%; P=0.25).

A geriatrician and specialised nurse home-visit during the first days following hospital discharge reduces the readmission rate for acute medical patients by almost 50%, compared to patients accompanied home or subsequently telephoned. Hospitalisation was reduced, but 30-day mortality did not differ significantly between groups.
