The Vienna consensus: report of an expert meeting on the development of art laboratory performance indicators

STUDY QUESTION: What are appropriate performance indicators (Pis) for ART laboratories for use in monitoring 'fresh' IVF and ICSI cycles? SUMMARY ANSWER: Minimum performance (competence) levels and aspirational (benchmark) values were recommended for a total of 19 indicators, including 12 key Pis (KPIs), five PIs and two reference indicators (RIs). WHAT IS ALREADY KNOWN: PIs are necessary for systematic monitoring of the laboratory and an important element within the Quality Management System. However, there are no established PIs for ART laboratories and there is very little evidence on the topic. STUDY DESIGN, SIZE, DURATION: This is the report of a 2-day consensus meeting of expert professionals. As a starting point for the discussion, two surveys were organized to collect information on indicators used in IVF laboratories. During the meeting, the results of the surveys, scientific evidence (where available), and personal clinical experience where integrated into presentations by experts on specific topics. After presentation, each proposed indicator was discussed until consensus was reached within the panel. PARTICIPANTS/MATERIALS, SETTING, METHODS: Expert professionals representing different countries and settings convened in the consensus meeting. MAIN RESULTS AND THE ROLE OF CHANCE: The paper is divided in two parts: the workshop report and the recommendations of the expert panel. The second part reflects the discussion on each of the indicators, with the agreed definition, competence level and benchmark value for each of the 19 indicators, including 12 KPIs, 5 PIs and 2 RIs. LIMITATIONS, REASONS FOR CAUTION: The KPIs are mainly based on expert opinion. Future research may warrant an update of the recommended KPIs, their definition and the competence level and benchmark values. WIDER IMPLICATIONS OF THE FINDINGS: Based on the information presented, each ART laboratory should select its own set of KPIs founded on laboratory organization, and processes.
