Importance of patient satisfaction with care in predicting osteoarthritis-specific health-related quality of life one year after total joint arthroplasty

Abstract

After previous results observed with a generic health-related quality of life (HRQoL) instrument, we aimed to confirm that immediate postoperative patient satisfaction with care predicts self-perceived health 1 year after total hip replacement/total knee replacement (THR/TKR), using an osteoarthritis (OA)-specific HRQoL questionnaire. This was a French multicenter prospective cohort study of patients after THR/TKR. HRQoL was assessed by the OsteoArthritis Knee and Hip Quality Of Life (OAKHQOL) instrument before and after surgery and satisfaction with care by the Quality of Care Scale (QCS). A total of 189 patients were followed up 12 months after discharge (mean age 68.9 SD = 8.5; 41.9% male). After adjustment for relevant variables, patients satisfied with care postoperatively showed greater 1-year postoperative HRQOL than those less satisfied with care. Patients satisfied with medical information had a higher postoperative HRQoL score than patients less satisfied in 3 of 5 OAKHQOL dimensions (P < 0.001 to P = 0.02), and patients satisfied with relationships with staff and daily routine scored higher on all HRQoL dimensions than did less-satisfied patients (all P < 0.001). These new findings with an OA-specific HRQOL questionnaire confirm that immediate postoperative satisfaction with care after THR/TKR for OA is a good predictor of self-perceived health status 1 year after surgery. Satisfaction with care therefore represents a relevant indicator of patient-reported health and is quickly accessible to clinicians.
