Existing selection methodologies are often insufficiently transparent or standardised and influenced by subjective opinions. To develop an instrument for evidence-based collection and evaluation of QIs that are suitable for quality monitoring, and which can be applied to various healthcare areas (HCAs; defined by care setting). The instrument was developed with HCA-specific experts, who provided feedback on its components and piloted its use in the Swiss context. We conducted a literature search with snowballing to identify prioritisation criteria and weighted these using the Analytic Hierarchy Process (AHP). We developed a template to facilitate data collection and the QI evaluation. The final QUALICATOR instrument consists of five steps: (1) definition of search scope; (2) utilisation of 12 prioritisation criteria across four dimensions (relevance, scientific soundness, usability, feasibility); (3) application of a data collection template objectifying the prioritisation criteria; (4) preselection via knockout criteria and (5) final prioritisation via weighting multicriteria decision analysis. Final criteria weights derived via the AHP varied substantially across HCAs (eg, relevance: 19.16%-57.10%; scientific soundness: 5.50%-39.50%; usability: 13.17%-33.75%; feasibility: 11.78%-45.57%), reflecting HCA-specific priorities.
