PRELIMINARY ASSESSMENT OF PATIENT SATISFACTION AND FUNCTIONAL IMPROVEMENT AFTER HIP REPLACEMENT SURGERY USING OXFORD HIP SCORE AND RELATED FACTORS

Abstract

Objectives: Preliminary assessment of patient satisfaction and functional improvement after hip replacement surgery by self-reported measure Oxford Hip Score and several related factors. Methods: descriptive, cross-sectional, prospective study on patients received hip replacement surgery at the Orthopaedics Center, Hue Central Hospital due to severe pain and functional limitation from 10/2014 to 04/2015. Results: 20 patients participated in the study with a mean age of 69.75 (male 52.15 and female 73.63). The main cause of hip replacement surgery is fracture (55%) and aseptic necrosis of the femoral head (30%). The percentageof poor OHS level is 85% in preoperative assessment. Mean OHS scoredat 3 month and 6 monthpostoperatively increased over 19 points, with a good and very good OHS level 50% and 60% respectively; the difference was statistically significant (p <0.05). The percentage of patients with poor function level at 6 month remained 30%. The proportion of patients achieved very satisfied and completely satisfied at 6 month is 80%. There are many factors affecting the degree of functionnal recovery and patient satisfaction after hip replacement therapy, but because of small number of subjects in our study, there is no clear statistical significance. Conclusion: Using the self-assessment scale Oxford Hip Score is a simple andcosteffective method with high validity and reliability for monitoring long-term changes of the hip joint function after hip replacement surgery. The high proportion of poor hip function level at 6 month after operation in our study may be due to many causes such as old age, co-morbidities, low preoperative OHS, complications after surgery, inadequate postoperative rehabilitation.
