Impact of community-based multidomain preventive health program on healthcare utilisation among elderly persons in Singapore: a propensity score matched and difference-in-differences study.

Objectives: Ageing populations present substantial challenges for healthcare systems. Community-based health worker (CHW) interventions for promoting healthy ageing and preventing/managing non-communicable diseases have gained considerable attention in recent years. This study aimed to assess the impacts of a multidomain preventive health initiative delivered by CHWs, specifically the 'My Health Map (MHM)' programme, on participants' health service utilisation using a propensity score matching methodology.
