A personalized questionnaire comprised of the Short Form 12(SF-12) and Western Ontario and Mc Master Universities(WOMAC) Index was mailed to patients at random time points ranging from 7 to 101 d prior to surgery. Nine independent factors were documented prospectively, including age, gender, ethnicity, marital status, type of surgery, surgeon, days prior to surgery(DPS) of survey mailing, WOMAC score and SF-12 score. The date of the completed survey receipt was also documented. For non-responders, the surveys were completed with the research team at the hospital upon admission. Multivariate regression and χ2 analysis were performed with Statistical Analysis Software software.RESULTS: DPS was the only factor that affected patient response. Mailing surveys 26 d to 31 d prior to surgery dates led to a peak response rate of 80% that was significantly higher(P < 0.023) than response rates for patients who were mailed their surveys ≤ 16 d(62.5%), 17 d to 25 d(70%) or ≥ 32 d prior to surgery(55%). No other factors, including preoperative WOMAC and SF-12 scores, significantly influenced response behavior.CONCLUSION: The DPS was independently the most significant predictor of response rates for pre-operative functional data among patients scheduled for hip and knee arthroplasty.展开更多
