|Abstract:||Background: Surgeons traditionally undertake a prospective evaluation of patients undergoing total hip arthroplasty in order to determine outcomes. The validity of doctor-derived data is questionable because of the potential for interobserver error, reporting bias, and differences between the perceptions of doctors and patients. Also, the use of doctor-derived data necessitates the use of costly outpatient services. Consequently, there are likely to be benefits associated with the use of patient-derived clinical evaluation data. However, few studies have focused on whether data obtained from the patient and doctor differ. Methods: The agreement between patient and doctor responses on a sixteen-item total hip arthroplasty clinical evaluation questionnaire completed at more than 2900 clinical assessments was determined. Data from repeated assessments performed preoperatively and postoperatively enabled stratified analyses that were used to examine reasons for disagreement and factors influencing agreement. Agreement was measured with use of the kappa coefficient. Results: For twelve of the sixteen items, the patient responses had acceptable agreement with the doctor responses. Some important differences between patient-derived and doctor-derived data were found. If the patient had other joint or health problems, had a revision total hip arthroplasty, or reported mild or moderate pain, there was a greater chance of reduced agreement on the pain items. Younger patients demonstrated better agreement with doctors than older patients did. Conclusions: Patients’ perceptions of symptoms and outcomes after total hip arthroplasty are relatively similar to those of their doctor. There is minimum risk of misinterpreting outcomes data by replacing doctor-completed questionnaires with patient-completed questionnaires in uncomplicated total hip arthroplasty cases. For patients with comorbid joint problems or other health problems, and for those reporting substantial pain, direct physician involvement in the evaluation of pain is recommended. The selective use of patient-completed questionnaires has the potential to substantially reduce the costs of outcomes evaluation programs by minimizing doctor input. Pending revision of some of the items, the use of this patient-completed questionnaire is advocated.|
