Drug Funding Decision-Making\ud in Hospital Formulary Committees in Germany

BACKGROUND: Hospital formularies are usually the gatekeepers for pharmaceutical drugs. Typical majority members of hospital formularies are physicians, although most of the time the formulary is chaired by a pharmacist. As German hospitals are struggling with a difficult economic environment the question arises: what kind of decision-making criteria are applied when pharmaceutical drugs should be added to the formulary list? Information regarding this topic is scarce due to the sensitive topic of decision-making.\ud \ud OBJECTIVES: Build a single decision-making framework which will be created to explain hospital drug funding decision-making and identify underlying mechanisms which explain processes and structures. The results can be used by hospitals to initiate knowledge sharing and provide a basis to analyse local formulary committee decision-making practice. Additionally, they can be used by the pharmaceutical industry to better adapt to the specific needs of the hospital decision-makers.\ud \ud METHODS: In this study, a mixed-methods approach has been used to confirm and further detail a preliminary hospital formulary decision-making framework derived from literature. An online survey was used to get insights on the structure of German hospital formularies and the relative importance of different decision-criteria. Additional semi-structured expert interviews were used to get in-depth information on the underlying mechanisms which influence decision-making on drug funding.\ud \ud RESULTS: Decisions for or against a pharmaceutical drug are influenced by a variety of perceived objective and specifically subjective criteria.\ud Despite a consistency in a dominant, high impact role of pharmacists and lead physicians every hospital formulary member has different relative weighting of decision criteria. Drug funding decision-making in German hospital formularies is highly individual but usually starts with a quasi-rational preference influenced by a mixture of analytic and intuitive criteria. The decision to use more analytic or more intuitive criteria is influenced by a variety of factors. The two most important ones are uncertainty and power. The resulting individual preference is then challenged and adapted in a group decision-making process
