Objective To explore the application effect of health belief model combined with Otago exercise programme in home rehabilitation of patients after total hip arthroplasty,aiming to provide references for clinical nursing practice. Methods Using convenience sampling method,60 patients undergoing total hip arthroplasty admitted to a tertiary hospital in Huzhou City from January to December 2022 were selected as the research subjects. They were randomly divided into an experimental group and a control group using SAS software,with 30 patients in each group. The experimental group received a health belief model combined with Otago exercise programme intervention program on the basis of routine care,while the control group received routine care for 3 months. The differences in functional exercise compliance scores,general self-efficacy scores,Harris hip joint function scores,and Barthel index scores were compared between 2 groups within 3 months. Results No participants dropped out in the 2 groups. The results of repeated measures analysis of variance showed that the time-group interaction effect of functional exercise compliance scores, general self-efficacy scores, hip joint function scores,and Barthel Index scores between the 2 groups at discharge and 1,2,and 3 months after discharge was statistically significant(P<0.001). The functional exercise compliance scores, general self-efficacy scores, hip joint function scores, and Barthel Index scores of the experimental group at 1,2,and 3 months after discharge were higher than those of the control group,and the differences were statistically significant(P<0.001). Conclusion The combination of health belief model and Otago exercise programme is beneficial for improving the functional exercise compliance of patients after total hip arthroplasty,enhancing self-efficacy,promoting hip joint function recovery,and thus enhancing daily living abilities.
