An interdisciplinary intervention is associated with overall improvement of older inpatients in a non-geriatric setting: A retrospective analysis of an observational, longitudinal study with one-year follow up

Older persons often loose independence during hospitalization. This analysis aimed at retrospectively evaluating the effects of a pilot individualized multidimensional intervention (IMI) on the comprehensive geriatric assessment (CGA)-based prognosis of older multimorbid patients in an acute internal medicine setting. Records from 72 patients aged 65 years and above who received the IMI were compared to those from 403 patients who received standard of care (SOC). All patients had undergone the CGA-based Multidimensional Prognostic Index (MPI) calculation on admission and at discharge. Patients were divided into three risk groups according to MPI score: Low-risk (MPI-1, 0-0.33), medium-risk (MPI-2, 0.34-0.66) and high-risk (MPI-3, 0.67-1). From admission to discharge, IMI patients showed significant improvements in their MPI score (P=0.014) and subdomains compared to SOC. This was particularly evident in MPI-2 and MPI-3 as well as in patients with poorer functions on MPI admission subdomains. An early geriatric intervention during hospitalization for disease-specific treatments in internal medicine settings improves overall individual prognosis in older multimorbid patients. Prospective randomized studies are needed to confirm these preliminary retrospective observations.
