Development of an Expectations Survey for Patients Undergoing Foot and Ankle Surgery

Background: Many authors have reported on patient satisfaction from foot and ankle surgery, but rarely on expectations, which may vary widely between patients and strongly affect satisfaction. In this study, we aimed to develop a patient-derived survey on expectations from foot and ankle surgery. Methods: We developed and tested our survey using a 3-phase process. Patients with a wide spectrum of foot and ankle diagnoses were enrolled. In phase 1, patients were interviewed preoperatively with open-ended questions about their expectations from surgery. Major concepts were grouped into categories that were used to form a draft survey. In phase 2, the survey was administered to preoperative patients on 2 occasions to establish test-retest reliability. In phase 3, the final survey items were selected based on weighted kappa values for response concordance and clinical relevance. Results: In phase 1, 94 preoperative patients volunteered 655 expectations. Twenty-nine representative categories were discerned by qualitative analysis and became the draft survey. In phase 2, another 60 patients completed the draft survey twice preoperatively. In phase 3, 23 items were retained for the final survey. For retained items, the average weighted kappa value was 0.54. An overall score was calculated based on the amount of improvement expected for each item on the survey and ranged from zero to 100, with higher scores indicating more expectations. For patients in phase 2, mean scores for both administrations were 65 and 66 and approximated normal distributions. The intraclass correlation coefficient between scores was 0.78. Conclusion: We developed a patient-derived survey specific to foot and ankle surgery that is valid, reliable, applicable to diverse diagnoses, and includes physical and psychological expectations. The survey generates an overall score that is easy to calculate and interpret, and thus offers a practical and comprehensive way to record patients' expectations. We believe this survey may be used preoperatively by surgeons to help guide patients' expectations and facilitate shared decision making. Level of Evidence: Level II, cross-sectional study.
