Health economic perspective on a community-based intervention for older people at risk of care dependency – results of a prospective quasi-experimental study

Abstract

This prospective, quasi-experimental study aims to compare healthcare resource utilization (HCRU) and costs of a multi-component care approach for older people in a community setting (intervention group (IG)) with usual care in a matched control group (CG) during a 21-month observation period. The reablement-oriented intervention included a geriatric assessment, a case and network management and digital supporting tools. Regression models were applied to determine intervention effects regarding hospitalization, total hospital length of stay (LOS), number of physician consultations, and healthcare costs using claims data. 872 subjects were included in the IG and 1,768 in the CG. The analyses showed that the intervention did not affect hospitalization ( OR = 1.153; 95% CI: 0.971–1.369, p = .105). However, participating in the IG lead to a small but significant increase of physician contacts by a factor of 1.078 (Exp( ß ) = 1.078; 95% CI: 1.011–1.149; p = .022). A non-significant mean difference in costs of €1,183 (95% CI: €−261.6 to €2,627.6, p = .108) per participant was identified. Further research is needed to generate robust evidence on the optimal design of care approaches for older people and the health economic implications of such interventions to improve care and resource allocation decision-making. Trial registration: The study was registered at the German Clinical Trials Register (DRKS00027866).
