Abstract:
Objective:To analyze the trajectory of outcome expectation and its influencing factors in patients undergoing total knee arthroplasty (TKA), so as to provide a basis for developing targeted intervention plans.Methods:A cross-sectional study was performed, by adopting convenient sampling method patients who undergoing TKA at orthopedic department of Suzhou Traditional Chinese Medicine Hospital from March 2021 to August 2022 were enrolled as respondents. They were investigated by general data questionnaire, Hospital for Special Surgery Knee Replacement Expectations Survey (HSS-KRES), and Hospital Anxiety and Depression Scale (HADS). The patients′ outcome expectation was assessed on the day of discharge and 3, 6, and 12 months after discharge, the potential categories of trajectory of outcome expectation were explored by latent class growth models, and the influencing factors were analyzed by multivariate Logistic regression.Results:Finally, 208 patients undergoing TKA were completed the survey, and there were 3 males and 3 females, aged 28-83(58.98 ± 14.53) years old. The scores of outcome expectation on the day of discharge and 3, 6, and 12 months after discharge were (56.18 ± 13.08), (50.92 ± 12.47), (48.43 ± 11.62), (46.26 ± 10.66) points respectively. The change trajectory of outcome expectation in patients undergoing TKA could be divided into three potential categories: high outcome expectation-slow decline group (21.6%, 45/208), medium outcome expectation-rapid decline group (45.2%, 94/208), low outcome expectation-stable decline group (33.2%, 69/208). Compared with the low outcome expectation-stable decline group, gender, age, and residential type were common influencing factors for the high outcome expectation-slow decline group and medium outcome expectation-rapid decline group ( OR values were 0.107-7.860, all P<0.05); depression subscale scores were independent influencing factor for the high outcome expectation-slow decline group ( OR=3.053, 95% CI 1.459-4.832, P<0.05). Conclusions:The change trajectory of outcome expectation of patients undergoing TKA varies, it is suggest that target evaluation and intervention can be carried out based the homogeneous group of patients with outcome expectation undergoing TKA.
