目的了解2型糖尿病(T2DM)患者发生心脑血管并发症的影响因素,构建列线图风险预测模型。
方法研究设计为前瞻性临床观察研究,研究对象选自黄山市人民医院2022年5月—2023年4月收治的T2DM住院患者。应用医院电子病历系统收集患者性别、年龄、体重指数、饮酒、吸烟情况、家族性疾病史、胰岛素使用情况、T2DM病程、血压及实验室检查结果。出院时进行T2DM患者特异性用药信念量表(总分10~50分)、药物素养评估量表(总分0~7分)、Morisky服药依从性量表(总分0~8分)测评;出院后电话随访6个月。以是否发生心脑血管并发症将患者分为2组。应用SPSS 26.0软件进行logistic回归分析,筛选T2DM患者出现心脑血管并发症的影响因素;应用R 4.1.0软件构建列线图预测模型,以Bootstrap法对列线图模型进行内部验证。
结果共294例T2DM患者纳入分析,用药信念评分为(32.6±5.6)分,药物素养评分为(4.2±0.5)分,服药依从性评分为(6.1±0.8)分。随访6个月,共有43例(14.6%)发生心脑血管并发症,包括冠心病(23例)、心力衰竭(12例)、脑卒中(8例)。与无心脑血管并发症组相比,心脑血管并发症组患者体重指数、糖化血红蛋白(HbA1c)、D-二聚体、血尿酸较高,用药信念评分、药物素养评分、服药依从性评分较低(均 P<0.05)。二元logistic回归分析结果显示,HbA1c、D-二聚体、血尿酸、用药信念、药物素养、服药依从性是T2DM患者发生心脑血管并发症的影响因素。依此建立列线图预测模型,内部验证结果显示,一致性指数为0.958,受试者工作特征曲线下面积为0.824,校准曲线趋近于理想曲线。
结论T2DM患者用药信念、药物素养和服药依从性现状并不理想。HbA1c、D-二聚体和血尿酸水平高,用药信念、药物素养和服药依从性差是T2DM患者发生心脑血管并发症的危险因素,综合多种因素建立列线图模型,对预测该类风险具有较高价值。
ObjectiveTo understand the influencing factors for cardio-cerebrovascular complications in patients with T2DM and construct a nomogram risk prediction.
MethodsThe study design was a prospective observational study, and the subjects were selected from hospitalized patients with T2DM admitted to Huangshan City People′s Hospital from May 2022 to April 2023. Data on patients' gender, age, body mass index, alcohol consumption, smoking status, family history of cardio-cerebrovascular diseases, insulin use, duration of diabetes, blood pressure, and routine laboratory test results were collected using the hospital electronic medical record system. At discharge, patients were assessed using the T2DM-Specific Medication Belief Scale (total score range: 10-50), Medication Literacy Assessment Scale (total score range: 0-7), and Morisky Medication Adherence Scale (total score range: 0-8). Patients were followed up by telephone for 6 months after discharge and divided into 2 groups based on the occurrence of cardio-cerebrovascular complications. Logistic regression analysis was performed using SPSS 26.0 software to identify influencing factors for cardio-cerebrovascular complications in T2DM patients. A nomogram prediction model was constructed using R 4.1.0 software, and internal validation of the model was conducted using the Bootstrap method.
ResultsA total of 294 T2DM patients were included in the analysis. The medication belief score was (32.6±5.6) score, the medication literacy score was (4.2±0.5) score, and the medication adherence score was (6.1±0.8) score. During the 6-month follow-up, a total of 43 patients (14.6%) experienced cardio-cerebrovascular complications, including of coronary heart disease (23 cases), heart failure (12 cases), and stroke (8 cases). Compared to patients without cardio-cerebrovascular complications, patients with complications had higher body mass index, glycosylated hemoglobin A1c (HbA1c), D-dimer, and uric acid levels, as well as lower medication belief scores, medication literacy scores, and medication adherence scores (all P<0.05). Binary logistic regression analysis showed that HbA1c, D-dimer, uric acid, medication belief, medication literacy, and medication adherence were influencing factors for cardio-cerebrovascular complications in T2DM patients. Accordingly, a nomogram prediction model was established. Internal validation results of the model showed that the concordance index was 0.958, the area under the receiver operating characteristic curve was 0.824, and the calibration curve was close to the ideal curve.
ConclusionsThe current status of medication belief, medication literacy, and medication adherence in T2DM patients was not ideal. High levels of HbA1c, D-dimer, and uric acid, as well as poor medication belief, medication literacy, and medication adherence were risk factors for cardio-cerebrovascular complications in T2DM patients. The nomogram model, which integrated multiple influencing factors, had high value in predicting the risks.
