INTRODUCTION: Pharmaceutical systems are frequently characterized by fragmentation, and competences for outpatient and inpatient sectors sit with different authorities, payers, and purchasers. This fragmentation of responsibilities can incentivize shifting expensive therapies and thus patients from one sector to the other. ***AREAS COVERED: Reimbursement and procurement policies in Europe addressing unwanted consequences of this fragmentation were identified through literature reviews and surveys with policy-makers. Good practice examples include cross-sectorial reimbursement lists managed by committees with representatives from the outpatient and hospital sectors, specific funding mechanisms, joint procurement involving purchasers from both sectors, actions against procurement contracts prohibiting generic competition, and an extension of Health Technology Assessment to the hospital sector. ***EXPERT OPINION: Recognizing fragmentation as a major challenge for pharmaceutical systems, policy-makers in some countries reacted by implementing policies to support cross-sectorial collaboration. However, only a handful of good practice examples exist for reimbursement and procurement policies in Europe. Though robust evaluations are lacking, there are indications that pharmaceutical policies which ensure collaboration at the interface of the outpatient and inpatient sectors would likely result in efficiency gains and better use of public budgets and may serve as lever to improve access to medicines.
