Geriatric co-management and interdisciplinary transitional care reduced hospital readmissions in frail older patients in Argentina: results from a randomized controlled trial.

BACKGROUND: Hospitalization is a moment of extreme vulnerability for frail older adults. There is scarce evidence on the effectiveness of geriatric co-management or transitional care interventions in Latin America. AIMS: To assess whether geriatric co-management combined with an interdisciplinary transitional care intervention could reduce 30-day hospital readmission rate compared to usual care in hospitalized frail older patients in a tertiary hospital in Argentina. METHODS: Single-blinded randomized controlled trial. Usual care treatment arm: all procedures performed during hospitalization were overseen by a senior internal medicine specialist and complied with pre-defined protocols. Patients had access to specialist care if needed, as well as hospital-at-home or home-based primary care services after discharge. Intervention treatment arm: in addition to usual care, a geriatric co-management team performed a comprehensive geriatric assessment during hospitalization, provided tailored recommendations to minimize geriatric syndromes and planned transition of care. A health and social care counselor oversaw continuity of care in patients' homes after discharge. RESULTS: We included 120 participants in each of the intervention and usual care (control) arms. Thirty-day hospital readmissions were 47.7% lower in the intervention arm (18.3% vs 35.0%; P = 0.040); and emergency room visits within the first 6 months after discharge were 27.8% lower (43.3% vs 60.0%; P = 0.010). There was a non-statistically significant decrease in 6-month mortality in the intervention arm (25.0% vs 35.0%; P = 0.124). CONCLUSION: Geriatric co-management of frail older patients during hospitalization combined with an interdisciplinary transitional care intervention reduced 30-day hospital readmissions and emergency visits 6 months after discharge.
