[Forms of Interprofessional Cooperation in Outpatient Health Care. A Cross-Case Analysis in German-Speaking Switzerland].

The quality of care for the chronically ill is to be improved through interprofessional cooperation (IPC). To date, evaluation projects on IPC have mostly focused on the inpatient sector. The aim was to use a multiple case study design to investigate forms of IPC in primary care and to identify facilitating and inhibiting factors. Factors that facilitated the implementation of IPC included having a responsible person employed to provide the service, supportive training, and the introduction of evidence-based interventions. There appeared to be insufficient incentives to implement IPC and the needs of the chronically ill were poorly integrated. More systematic evaluation of IPC initiatives is needed to demonstrate their added value. Greater integration of patient needs is key.
