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

Abstract

Category: Other Introduction/Purpose: Functional outcomes scores routinely used in orthopedic research are limited in that they are developed solely from a surgeon’s perspective. Very few studies have investigated patients’ expectations from foot and ankle surgery. Many authors have reported on patient satisfaction, but rarely on expectations, which may vary widely between patients and even strongly affect satisfaction. In this cross-sectional study, we aimed to develop and test a patient-derived expectations survey for patients undergoing foot and ankle surgery. Methods: Using a three-phase process, we developed and tested a patient-derived expectations survey. Patients with a wide spectrum of foot and ankle diagnoses were enrolled, including the major diagnoses of ankle arthritis, ankle instability, ankle osteochondral lesions, flatfoot deformity, hallux valgus, and hallux rigidus. In phase 1, patients were interviewed preoperatively with open-ended questions about their expectations from surgery. Responses were independently assessed by three reviewers using qualitative techniques. Major concepts were grouped into categories which were used to form a draft survey. In phase 2, the survey was administered to preoperative patients on two 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, and a scoring rubric was developed. Results: In phase 1, 94 preoperative patients with diverse foot or ankle pathology (mean age 50 ± 15 years, 63% women) volunteered 655 expectations. 29 representative categories were discerned by qualitative analysis and became the draft survey. In phase 2, another 60 patients (mean age 55 ± 15 years, 60% women) completed the draft survey twice preoperatively, separated by an average of 4 days. In phase 3, 23 items were retained for the final survey. For retained items, the average weighted kappa value was 0.54 (Table). An overall score is calculated based on the number of expectations and the amount of improvement expected and ranges from 0-100, with higher scores indicating more expectations. For patients in phase 2, mean scores for both administrations were 65 and 66 and approximated normal distributions. Cronbach alpha coefficients were 0.88 and 0.90, and 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, and applicable to diverse diagnoses. It measures physical as well as psychological expectations, encompassing symptoms, function, mobility, work and social activities, exercise/sports, pain medications, shoewear, and appearance. 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. In the future, this survey may be used as a means to assess patient satisfaction with surgery as determined by the fulfillment of their expectations.
