Under the Age Well SG national programme, active ageing centres (AACs) will evolve to better support older persons to age actively, stay socially connected, and be cared for within their communities. Improvements to the operating model of AACs will seek to enhance accessibility and convenience to older persons, improve the range and quality of programmes and increase collaboration with community partners and healthcare providers to bring activities and services into the community, nearer to older persons. The objective of this project is to (i) understand the context and mechanisms of implementing the (new) AAC model, (ii) evaluate its effectiveness, and (iii) co-develop a practical toolkit to help individual centres implement the model and achieve Age Well SG objectives. This project is funded by the Agency for Integrated Care.
