Developing consensus on core outcome domains and measurement instruments for assessing effectiveness in perioperative pain management after sternotomy, breast cancer surgery, total knee arthroplasty and surgery related to endometriosis

Evidence synthesis of clinical trials requires consistent outcome assessment. For pain management after surgery inconsistency of effectiveness assessment is still observed. A subproject of IMI PainCare (Innovative Medicine Initiatives, aims for identifying core outcome domains and measurement instruments for effectiveness and efficacy of perioperative pain management after surgery in four surgical fields (sternotomy, breast cancer surgery, total knee arthroplasty and surgery related to endometriosis) in order to harmonize outcome assessment for perioperative pain management.

A multifaceted process will be performed according to existing guidelines (Core Outcome Measures in Effectiveness Trials (COMET), COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)). In a first step, outcome domains will be identified via systematic literature review and consented on during a one-day consensus meeting by 10 stakeholder groups, including patient representatives, forming an IMI PROMPT consensus panel. In a second step outcome measurement instruments regarding the beforehand consented core outcome domains and their psychometric properties will be searched for via systematic literature review and approved by COSMIN checklist for study quality and scale quality separately. In a three step online survey the IMI PROMPT consensus panel will vote for most suitable measurement instruments. The process is planned to be conducted between 11/2017 (systematic literature review on common outcome domains) and 3/2023 (final voting on core outcome measurements).
