Brief Title: Development of a Patient-Reported Outcome Measure to Assess Recovery After Abdominal Surgery
Official Title: Value-Based Care in Abdominal Surgery: Measuring Recovery Outcomes That Matter to Patients
Brief Summary: As surgery enters the era of value-based care, it is advocated that postoperative recovery be measured using patient-reported outcomes (PROs) as they provide a mean to incorporate the patient's perspectives and experiences into research and clinical decision-making. In abdominal surgery, this is currently precluded by the lack of PRO measures specifically developed and validated in the context of postoperative recovery. The core goal of this research project is to develop a PRO measure aimed to assess postoperative recovery from the perspective of patients undergoing abdominal surgery. This project complies with the US Food and Drug Administration (FDA) and International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines for PRO development and will be conducted in three phases: Phase 1: Qualitative interviews with patients to develop a conceptual framework and generate relevant items. Phase 2: Use of Rasch Analysis for item-reduction and scale formation. Phase 3: Further assessment of measurement properties based on traditional psychometric methods.
Detailed Description: OBJECTIVE: To develop a comprehensive, conceptually relevant and psychometrically sound PRO measure to assess recovery after abdominal surgery. OUTLINE: - Phase 1(Conceptual framework and item generation): Semi-structured interviews focusing on patient lived experiences after abdominal surgery are currently being conducted to derive the "final conceptual framework of recovery after abdominal surgery". The interviews are guided by the "hypothesized conceptual framework" which is based on previous literature and expert input. This phase has a minimal targeted sample of 30 patients. To account for potential cross-cultural differences in recovery experiences, the study is enrolling patients from 5 international sites: McGill University Health Centre (Montreal, Canada), Hospital Sao Paulo (Sao Paulo, Brazil), Vita-Salute San Raffaele Hospital (Milan, Italy, Hokkaido University Hospital (Sapporo, Japan) and Hospital (TBE, USA). Interview audio recordings are transcribed, translated if required, and coded according to ICF (International Classification of Functioning, Disability and Health) domains. Codes for which saturation is reached will comprise the final conceptual framework of recovery. Items reflecting the essence of each domain will be generated and patient understanding of the items will be assessed through cognitive interviews. Items for which no problems have been identified and those successfully revised will be compiled into an item pool to be 'calibrated' in subsequent stages of PRO development. - Phase 2: (Rasch Analysis): Estimate the extent to which the pool of items generated in Phase 1 fit the Rasch model and, based on this analysis, modify or eliminate items to ensure that the novel PRO measure fits a linear continuum and produces meaningful scores. Phase 2 targets a sample of 300 patients and the preliminary item pool will be administered at one time point either in pen-and-paper format or using an online survey, depending on the patient's preference. Based on the analysis, a computer adaptive testing (CAT) system will be developed to allow accurate measurement of PRO scores using a minimal number of items. - Phase 3: (Validation using traditional psychometric methods ): Use traditional psychometric methods to contribute further evidence regarding the measurement properties of the novel PRO measure of recovery after abdominal surgery. To do so, the final PRO measure in CAT format will be administered to a consecutive cohort of patients undergoing abdominal surgery (target sample size of 200) in two institutions (MUHC and Florida Hospital) preoperatively and at postoperative days 3, 7, 15, 30 and 90.
