AbstractPerioperative acute kidney injury is a common problem. While clinical trials seek to evaluate the impact of interventions on a variety of primary and secondary endpoints with the aim of implementing this knowledge to improve perioperative outcomes, the use of valid and relevant endpoints within clinical trials is of critical importance to achieving this goal. Suitable endpoints must be validated for the study population and in light of the clinical context under investigation while also considering regulatory requirements that govern the licensing of new therapeutic agents as well as the values of patients whose outcomes we seek to improve. Heterogeneity in perioperative clinical trial endpoints and their definitions limits the ability to compare and interpret differences in outcomes across studies or to pool outcomes from different studies in meta-analysis. The Standardized Endpoints in Perioperative Medicine (StEP) initiative is an international collaboration whose goal is to identify and recommend a suite of clearly and precisely defined endpoints across multiple domains, specifically suited for use in perioperative clinical trials. The current review describes the rationale, goals and the planned pathway of the StEP renal subgroup. Development of a set of standardized and core renal endpoints, valid and relevant for use in the perioperative context, precisely defined and yet with sufficient flexibility to encourage broad uptake and application should facilitate high-quality and practice-changing perioperative research into the future.© 2017 S.
