[A population-targeted approach to connect prevention, care and welfare: visualising the trend].

To map initiatives in the Netherlands using a population-targeted approach to link prevention, care and welfare.Descriptive investigation, based on conversations and structured interviews.We searched for initiatives in which providers in the areas of prevention, care and welfare together with health insurers and/or local authorities attempted to provide the 'triple aim': improving the health of the population and the quality of care, and managing costs. We found potential initiatives on the basis of interviews with key figures, project databases and congress programmes. We looked for additional information on websites and via contact persons to gather additional information to determine whether the initiative met the inclusion criteria. An initiative should link prevention, care and welfare with a minimum of three players actively pursuing a population-targeted goal through multiple interventions for a non-disease specific and district-transcending population. We described the goal, organisational structure, parties involved, activities and funding on the basis of interviews conducted in the period August-December 2015 with the managers of the initiatives included.We found 19 initiatives which met the criteria where there was experimentation with organisational forms, levels of participation, interventions and funding. It was noticeable that the interventions mostly concerned medical care. There was a lack of insight into the 'triple aim', mostly because data exchange between parties is generally difficult.There is an increasing number of initiatives that follow a population-targeted approach. Although the different parties strive to connect the three domains, they are still searching for an optimal collaboration, organisational form, data exchange and financing.
