[目的]探讨信息-动机-行为(IMB)模型的护理干预在膝关节内侧单间室退变患者膝关节置换术后康复中的应用价值.[方法]选取本院因膝关节内侧单间室退变行膝关节置换术的患者 90例,按照随机数表法分为观察组和对照组.对照组采用常规护理,观察组在对照组基础上采用IMB模型护理,比较两组干预前后自我效能(SER)评分、焦虑自评量表(SAS)评分、抑郁自评量表(SDS)评分、膝关节功能(HSS)评分变化情况及遵医行为,并统计两组术后并发症发生情况及护理满意度.[结果]干预后,观察组SER评分高于对照组,SAS、SDS评分低于对照组(P ＜0.05);观察组总依从率为 95.56%(43/45),高于对照组的77.78%(35/45)(P ＜0.05);干预后两组 HSS评分均高于干预前,且观察组干预后 HSS评分高于对照组(P ＜0.05);观察组并发症发生率为 2.22%(1/45),低于对照组的17.78%(8/45)(P ＜0.05);观察组护理满意度为 97.78%(44/45),高于对照组的 80.00%(36/45)(P ＜0.05).[结论]IMB模型的护理干预可改善膝关节内侧单间室退变患者膝关节置换手术后负性心理情绪,提高其自我效能及遵医行为,降低并发症发生率,促进膝关节功能恢复,且护理满意度高,值得临床推广应用.“,”[Objective]To explore the application value of nursing intervention of information-motivation-be-havior (IMB)model in postoperative rehabilitation of knee joint replacement in patients with unilateral posterior chamber degeneration of knee joint.[Methods]A total of 90 cases of internal single compartment degeneration in the knee joint of our hospital were selected and divided into the observation and control groups according to the random number table method.Patients in the control group received routine nursing intervention,while patients in the observation group were treated with nursing intervention of IMB model on the basis of routine nursing.The self-efficacy rating (SER)score,the self-rating Anxiety Scale (SAS)score,the self-rating of Depression Scale (SDS)score,the change of the knee joint function (HSS)score and the compliance behavior before and after the intervention of two groups were observed and compared.The postoperative complications and nursing satisfaction were also compared between the two groups.[Results]After intervention,the SER score of the observation group was higher than that of the control group,while the scores of SAS and SDS were lower than those of the control group(P ＜0.05).The total compliance rate of the observation group was 95.56%(43/45),which was higher than that of the control group 77.78%(35/45)(P ＜0.05).After intervention,the HSS scores of the two groups were higher than those before intervention,and the HSS score of the observation group was higher than that of the control group(P ＜0.05).The complication rate in the observation group was 2.22%(1/45),which was lower than that in the control group 17.78%(8/45)(P ＜0.05).The nursing satisfaction of the observation group was 97.78%(44/45),which was higher than that of the control group 80%(36/45)(P ＜0.05).[Conclusion]The nursing intervention of IMB model after knee joint replacement surgery can improve the negative psychological e-motion of the patients with unilateral compartment degeneration,improve their self-efficacy and compliance behav-ior,reduce the incidence of complications,and promote the recovery of the knee joint function.In addition,it has high nursing satisfaction and is worthy of clinical application.
