'The Billion Dollar Question': Embedding Prevention in Older People's Services--Ten 'High-Impact' Changes

Against this background, this commentary reviews national and international evidence around ten policy measures and interventions, highlighting some of the most promising approaches as well as the fragmented and contested nature of the evidence base.
