摘要：目的构建手术室护士下肢静脉曲张风险预测模型,并验证模型的预测效果。方法2022年1-5月选取甘肃省兰州市三级医院9家、二级医院7家的手术室护士512名,按7∶3比例随机分配至建模组和验证组,采用单因素、多因素logistic回归模型筛选手术室护士发生下肢静脉曲张的独立影响因素,采用随机森林算法对影响因素的重要性排序,R软件建立列线图模型并将其制成动态列线图网页格式。结果建模组纳入手术室护士337例,患下肢静脉曲张167例,患病率为49.6%。护龄、学历、站立时间大于或等于4 h、工作性质、每周穿静脉曲张袜时间小于3 d为手术室护士罹患下肢静脉曲张的影响因素。重要性影响因素排序为护龄、学历、工作性质、每周穿静脉曲张袜的时间、站立时间;内部验证受试者工作特征曲线下面积为0.696,校准图中校准曲线接近对角线;外部验证受试者工作特征曲线下面积为0.683,校准图中校准曲线较接近对角线。结论该列线图模型具有较好的一致性和区分度,动态列线图网页简单易行,能快速评价自身危险分值,筛选高危人群,可作为个体化预防方案实施的基础,也为手术室护理管理者合理排班提供参考依据。
Objective To construct a risk prediction model for lower extremity varicose veins in operating room nurses,and to verify the prediction effect of the model.Methods A total of 512 operating room nurses from nine tertiary hospitals and seven secondary hospitals in Lanzhou City from January to May 2022 were selected and randomly assigned to the modeling group and the validation group in a ratio of 7∶3.A univariate,multivariate logistic regression was used to screen the independent factors influencing the development of lower extremity varicose veins in operating room nurses.A random forest algorithm was used to rank the importance of the influencing factors.The R software was used to establish a nomogram model and make it into a dynamic nomogram web page format.Results In the modeling group,337 operating room nurses were included,and 167 patients had lower extremity varicose veins,with a prevalence of 49.6%.Nursing age,education,standing time≥4 hours,work nature,and the number of days of wearing varicose stockings per week≥3 days were the influencing factors of lower extremity varicose veins in operating room nurses.The ranking results on the importance of influence were as follows:Nursing age>education>work nature>wearing varicose stockings≥three days per week>standing time.The area under the ROC curve of internal verification AUC value was 0.696,and the curve in the calibration chart was close to the diagonal line.The AUC value of the area under the external validation ROC curve is 0.683,and the curve in the calibration chart was nearly close to the diagonal line.Conclusion The nomogram model has good consistency and distinction,and the dynamic nomogram web page is simple and easy to use,which can quickly evaluate their own risk scores and screen high-risk groups,and can be used as the basis for the implementation of individualized preventive programs,as well as providing a reference basis for rational scheduling for nursing managers in the operating room.
