The Learning Rehabilitation System: Strengthening an intersectoral strategy to improve functioning of an ageing population.

Rehabilitation uses a person-centred approach that relies on dynamic case management and works across sectors, including social protection, labour, and education to improve individual functioning. Global population ageing means that more people will live with impairment in functioning. Responding to this growth in impairment will require countries to strengthen rehabilitation at all levels of their health systems as highlighted by the 2023 WHO Resolution on Rehabilitation. Efforts to strengthen rehabilitation can benefit from the concept of the Learning Health System, which implies a cyclical process of identifying issues, developing and implementing responses, monitoring the consequences of systems' change, and revising the response. However, we argue that it is not enough to simply adopt the notion of the Learning Health System for strengthening rehabilitation. We should rather think of a Learning Rehabilitation System. This is because rehabilitation is an intrinsically inter-sectoral strategy given its focus on people's functioning in their daily lives. Therefore, we believe that introducing the notion of the Learning Rehabilitation System is more than a terminological change; it is a fundamental programmatic shift that can contribute towards the goal of strengthening rehabilitation as an intersectoral strategy to improve functioning of an ageing population.
