Abstract:
Objective:To explore the effect of the intervention model based on the theory of knowledge, belief and action on the prevention of dislocation of prosthesis after hip replacement by nurses, so as to provide guidance for the management of prosthesis dislocation prevention after hip replacement.Methods:The patients were from Shenzhen Luohu People′s Hospital. From January to March 2018, 82 patients who underwent artificial total hip arthroplasty were set as the control group and received routine care. The 76 patients who underwent artificial total hip arthroplasty from May to July 2018 were set as the observation group, and the intervention model based on the theory of knowledge, belief and action was adopted. The incidence of prosthesis dislocation was compared between the two groups at 1, 3, 6 months after operation. At the same time, the Harris hip function score and the activity of daily living (ADL) score were compared between the two groups at the time of discharge, 1, 3, 6 months after operation.Results:The total incidence of prosthesis dislocation at 6 months was 1.32% (1/76) and 9.76% (8/82) in the experimental group and the control group, respectively, and the difference was statistically significant ( χ2=5.23, P<0.05). At discharge, there was no significant difference in the Harris hip function score and ADL scores between the two groups ( P>0.05). The Harris hip function score and ADL scores at 1, 3, 6 months after operation were (80.05 ± 6.72), (88.76 ± 5.84), (94.07 ± 4.43) points and (55.72 ± 16.61), (63.55 ± 14.55), (75.39 ± 12.27) points in the observation group, and (74.41 ± 6.26), (84.48±5.97), (89.30 ± 5.32) points and (47.13 ± 19.77), (56.71 ± 16.01), (63.96 ± 13.78) points in the control group, the differences were statistically significant ( t values were -6.08--2.80, all P<0.05). Conclusions:The intervention model based on the theory of knowledge, belief and action can effectively improve the Harris hip function score and ADL score of patients at 1, 3, 6 months after hip replacement, and reduce the incidence of prosthetic dislocation.
