The virtue of optimistic realism - expectation fulfillment predicts patient-rated global effectiveness of total hip arthroplasty.

BACKGROUND: Emerging evidence highlights the importance of preoperative expectations in predicting patient-reported outcomes of orthopedic surgeries. To date, it is still a matter of controversy whether patient satisfaction can be maximized by promoting either optimistic or realistic outcome expectations before surgery. Adjusting overly optimistic outcome expectancies in favor of a more realistic outlook on the limitations of total hip arthroplasty could reduce the risk of disappointment and lead to greater satisfaction with surgery outcomes. Our prospective cohort study was aimed at comparing the relative predictive influence of baseline expectations, expectation fulfillment and symptomatic improvement on the global effectiveness of total hip arthroplasty. METHODS: Ninety patients (49 female, 41 male; mean age: 63 ± 12.87 years) fulfilled inclusion criteria and completed a comprehensive preoperative assessment comprising sociodemographic, clinical, functional and psychological phenotypes. Moreover, the strengths of preoperative expectations for improvements in eight pain-related and functional domains were recorded on a 5-point Likert-scale. At 12 months after surgery, patients were asked to rate perceived improvements in each of these domains as well as the global effectiveness of the total hip replacement on a 5-point Likert-scale. To evaluate the relative impact of preoperative expectations, symptom improvement and the fulfillment of expectations on the global effectiveness of surgery, a sequential multiple regression analysis was performed. RESULTS: Compared with the actual improvement at 12-months follow-up, prior expectations had been overly optimistic in about 28% of patients for hip pain, in about 45% for walking ability and around 60% for back pain, independence in everyday life, physical exercise, general function social interactions and mental well-being. An optimistic hip pain expectation, walking ability at baseline and the fulfillment of expectations for walking ability, general function and independence in everyday life were found to independently predict global effectiveness ratings. CONCLUSIONS: Positive expectation about pain and the fulfillment of expectations concerning functional domains predicted higher global effectiveness ratings. In line with many authors investigating the relationship between the fulfillment of expectations and satisfaction with medical interventions, we suggest that professionals should explicitly address their patients' expectations during the preoperative education and consultation.

The influence of pain expectation on pain experience after orthopedic surgery: an observational cohort study.

BACKGROUND: Current literature about the effects of patients' expectations on relevant outcome measures is still conflicting and incomplete. The aim of this prospective observational study was to assess the influence of expectations and the fulfillment of expectations on postoperative pain intensity and pain relief. Furthermore, clinical characteristics influencing expectations and the fulfillment of expectations were explored. METHODS: Patients undergoing elective orthopedic surgery were assessed using two standardized self-report questionnaires on the day before surgery and the third postoperative day. One hundred and seventy patients from 21 to 93 years (average age 64.6, SD 14.0 years; 55% female) were consecutively included. RESULTS: While expectations of pain intensity did not correlate with pain experience after surgery, the fulfillment of expectations was associated with postoperative pain experience. Patients whose expectations were fulfilled were found to be more satisfied with the overall treatment as compared to those whose expectations were not fulfilled. Higher levels of expected pain were associated with higher fear of surgery and fear of postoperative pain. Preoperative pain intensity, length of treatment before the surgery, fear of surgery, helplessness and fear of postoperative pain were associated with higher postoperative pain intensity. Lower levels of preoperative fear of surgery and fear of postoperative pain were found to correlate with the fulfillment of pain relief. CONCLUSIONS: Our study indicates that postoperative pain and satisfaction with the treatment are associated with the degree of fulfillment of expectations rather than the expected pain itself.
