EVALUATION OF PATIENT CONCERNS BEFORE TOTAL KNEE OR HIP REPLACEMENT



Abstract

This study was performed to evaluate the pre-operative concerns of patients undergoing total knee or hip replacement surgery.

A cross-sectional study of 370 patients was performed. The patients completed a postal questionnaire on 29 concerns, each rated on a scale of 1 (not concerned) to 4 (very concerned). SF-12 and Oxford knee or hip scores were also calculated. Analysis was carried out using chi-squared tests on SPSS.

217 questionnaires were returned. The results showed that the greatest concern for patients was cancellation of their operation. This was followed by failure of the operation to reduce pain, loss of a limb and joint infection. Concerns regarding scar problems, nursing care and preoperative tests were the lowest.

Women showed statistically significant greater concerns in 9 areas. Younger patients (age< 65) showed increased concerns in 8 areas. Patients who had previously undergone joint replacement were less concerned than those who had not had previous lower limb joint replacements for 6 responses. They showed increased concern in 2 areas, nursing care and hospital food. Those undergoing total hip replacement were more concerned about dislocation, dressing and returning to work (all p< 0.05). The mean Oxford Knee or Hip Score was 42.96 and 45.12 respectively (scale 12–60, 60 being most severe symptoms). The mean SF-12 scores were 41.14 for the mental component and 28.70 for the physical component score (scale 0–100, 100 representing greatest level of good health).

The mean level of concern is low at 1.9 (scale 1 to 4). It is encouraging that patients who have had a previous joint replacement are generally less concerned. Possible reasons for increased concerns amongst women and younger patients are discussed. SF-12 and Oxford Knee/Hip Scores are comparable with other studies.

In conclusion, this study provides useful information for the preoperative counselling of patients, production of preoperative literature and for improving the service we offer to our patients.
