Objective To explore and analyze the effects of a comprehensive intervention based on integrated care on the frailty of elderly stable coronary heart disease（CHD）patients．Methods From August 2021 to June 2022,78 cases of elderly stable CHD patients who were diagnosed and treated in Zhumadian City Hospital of Traditional Chinese Medicine were selected．According to a 1：1 random number table method,78 patients were divided into the integrated group and the traditional group,with 39 cases of each group．The traditional group was given routine care,while the integrated group was given a comprehensive intervention based on integrated care concepts on the basis of the traditional group's care,and the patients' prognosis was recorded．Results The balance test scores and chair stand test scores of both groups after 3 months of nursing care were lower than those before nursing care．The balance test scores and chair stand test scores of the integrated group after 3 months of nursing care were also significantly lower than those of the traditional group（P<0.05）．After 3 months of nursing care,the quality of life scores in physical,psychological,social,and spiritual dimensions in the integrated group were significantly higher than those in the traditional group（P<0.05）．The incidence of major cardiovascular adverse events such as cardiac death,myocardial infarction,target vessel reconstruction,and coronary artery restenosis during a one-year follow-up in the integrated group was 5.13%,compared to 25.64% in the traditional group．The integrated group was significantly lower than the traditional group（P<0.05）．Conclusions The application of a comprehensive intervention based on integrated care concept in elderly stable CHD patients can alleviate frailty,improve quality of life,and reduce the incidence of major cardiovascular adverse events．

       目的   基于Nomogram初步构建膝骨关节炎（KOA）患者术前衰弱的风险预测模型。方法   便利选取172例于2021年12月—2022年8月在广州市某三甲医院关节外科接受择期膝关节置换术的KOA患者为研究对象，依据衰弱的发生与否分为衰弱组（n=111）和非衰弱组（n=61），通过单因素分析筛选变量，纳入Logistic回归分析，并构建列线图模型。结果   单因素分析结果显示年龄、BMI、膝关节疼痛年限、合并症、抑郁、焦虑、疼痛、睡眠障碍、营养状况等在不同组间比较差异存在统计学的意义（P＜0.05）。多因素Logistic回归分析表明，BMI异常（OR=3.360）、膝关节疼痛年限＞5年（OR=14.188）、抑郁（OR=5.608）、睡眠障碍（OR=25.480）是KOA患者术前衰弱的独立危险因素（P＜0.05）。基于此，建立了预测膝骨关节炎患者术前衰弱风险的列线图预测模型。结果显示C-index为0.915，校正曲线接近理想曲线，ROC曲线下面积（AUC）为0.919（95%CI：0.878~0.961），可见该预测模型具有较好的区分度和准确度。结论   根据BMI、膝关节疼痛年限、抑郁以及睡眠障碍这四个独立危险因素，可以准确地预测膝骨关节炎患者术前衰弱的风险。
