血液透析合并高血压患者家庭血压监测知识与依从性状况及其相关性

Correlation between compliance and knowledge of home blood pressure monitoring in chronic kidney disease patients with hypertension

目的探讨血液透析合并高血压患者家庭血压监测知识与依从性状况及其相关性,为制定血液透析患者家庭血压监测干预策略提供理论参考。方法本研究采用横断面研究方法,通过便利抽样法,选择2018年10月至2019年10月广东省某三级甲等综合医院血液透析中心120例维持性血液透析合并高血压患者,采用慢性肾脏病患者家庭血压监测知识与慢性肾脏病患者家庭血压监测依从性量表对患者进行问卷调查。采用Pearson相关分析患者家庭血压监测知识及其各维度与家庭血压监测依从性的相关性。采用多重线性回归分析法,进一步探讨患者家庭血压监测知识对家庭血压监测依从性的影响。结果117例患者完成研究。患者最近1个月家庭血压监测知识总分(33.03±9.53)分,其中高血压防治知识(15.62±5.02)分,血压监测知识(17.41±5.95)分;家庭血压监测依从性总分(25.94±9.09)分。患者家庭血压监测知识总分以及高血压防治知识得分、血压监测知识得分均与家庭血压监测依从性水平呈正相关(r=0.342,r=0.269,r=0.321,均P<0.05)。在控制混杂因素后,多因素分析显示,患者血压监测知识得分为家庭血压监测依从性的影响因素(P<0.01)。结论血液透析合并高血压患者家庭血压监测知识与依从性均处于中等水平,家庭血压监测知识越高者其家庭血压监测依从性也越高。提高患者家庭血压监测知识水平有助于改善其家庭血压监测依从性。

Objective To investigate the compliance and knowledge of home blood pressure monitoring(HBPM)in chronic kidney disease patients with hypertension so as to provide a theoretical reference in development of the interventional strategies for improving the patient compliance.Methods From October 2018 to October 2019,a cross-sectional study was conducted among 120 hypertensive patients who underwent maintenance haemodialysis in the haemodialysis centre of a tertiary hospital in Guangdong Province.The patients were selected by convenience sampling method.The survey was carried out by using the HBPM adherence scale and the HBPM knowledge questionnaire.Pearson correlation analysis was conducted to explore the correlation between the compliance and knowledge of HBPM and multiple linear regression was employed to further explore the influence of HBPM knowledge on HBPM compliance.Results Among the 120 participants,117 completed the study.The total score of HBPM adherence scale in the recent month was(25.94±9.09).The total score of HBPM knowledge was(33.03±9.53),by combining the hypertension prevention knowledge(15.62±5.02)and blood pressure monitoring knowledge(17.41±5.95).The total score of HBPM knowledge,the score of hypertension prevention knowledge and the score of blood pressure monitoring knowledge were positively correlated with the compliance with HBPM(r=0.342,0.269,0.321,respectively,all P<0.05).Multivariate analysis showed that with a control of confounding factors,the patients with high total score of blood pressure monitoring knowledge had higher compliance(P<0.01).It explained a 21.6%of variation.Conclusions Among chronic kidney disease patients with hypertension,the compliance with HBPM was above the average and the knowledge of HBPM was moderate.The patients with a higher total score of HBPM knowledge had a higher compliance with HBPM.It is helpful for the patient to improve the compliance with HBPM,therefore to improve the knowledge of HBPM for the patients.
