Stokes, Jonathan ; Struckmann, Verena ; Kristensen, Søren Rud ; Fuchs, Sabine ; van Ginneken, Ewout ; Tsiachristas, Apostoles ; Rutten-van Mölken, Maureen ; Sutton, Matt (2018-07-11)

Traditional provider payment mechanisms may not create appropriate incentives for integrating care. Alternative payment mechanisms, such as bundled payments, have been introduced without uniform definitions, and existing payment typologies are not suitable for describing them. We use a systematic review combined with example integrated care programmes identified from practice in the Horizon2020...
