老年患者麻醉手术中压力性损伤发生情况调查及其预测模型的建立OACSTPCD
Investigation of the occurrence of pressure ulcer during anesthetic surgery in elderly pa-tients and establishment of prediction model
目的 调查老年患者麻醉手术中压力性损伤的发生情况,建立预测风险的列线图模型并进行内部验证.方法 回顾性分析 2018-02 至 2020-08 在南充市中心医院进行麻醉手术的老年患者 327 例.收集麻醉手术中可能发生压力性损伤的因素,根据有无压力性损伤分为两组,比较其差异,并采用多因素Logistic回归分析压力性损伤的影响因素,并建立列线图预测模型进行内部验证.结果 327 例都完成了皮肤情况的观察,观察期间共 41 例(12.53%)出现压力性损伤.通过LASSO回归模型筛选出 9 个潜在的影响因素,并行多因素Logisitc回归分析,结果显示,年龄、BMI、吸烟史、手术体位、术中变换体位、手术时间、术中低温、白蛋白水平是老年患者麻醉手术中发生压力性损伤的独立性影响因素(P<0.05).ROC曲线显示模型预测老年患者麻醉手术中发生压力性损伤的AUC为 0.926(95%CI:0.888～0.965);校准曲线和H-L拟合优度检验结果显示,该列线图模型预测的概率与实际概率差异无统计学意义(P>0.05).结论 老年患者麻醉手术中压力性损伤发生率较高,主要受年龄、BMI、吸烟史等因素影响,根据上述因素建立的列线图模型预测麻醉手术中压力性损伤具有较高的准确度与区分度.
Objective To investigate the occurrence of pressure ulcer in elderly patients during anesthetic surgery,and to es-tablish a nomogram model to predict the risk and conduct internal verification.Methods A total of 327 elderly patients who underwent anesthetic surgery in Nanchong Central Hospital from February 2018 to August 2020 were selected for retrospective analysis.The factors that might cause pressure ulcer during anesthetic surgery were collected,and the patients were divided into two groups according to whether or not there was pressure ulcer.The differences were compared,and the influencing factors of pressure ulcer were analyzed by multi-factor Logistic regression,and a nomogram prediction model was established for internal verification.Results The skin condition of 327 cases was observed.During the observation period,41 cases(12.53%)suffered from pressure ulcer.Nine potential influencing factors were screened by LASSO regression model,and multi-factor Logistic regression analysis showed that age,body mass index(BMI),smoking history,special posture during operation,changing posture during operation,operation time,temperature during op-eration,and albumin level were the independent influencing factors for the occurrence of pressure ulcer during anesthetic surgery in eld-erly patients(P<0.05).The ROC curve showed that the AUC of the model predicting pressure ulcer during anesthesia in elderly pa-tients was 0.926(95%CI:0.888 to 0.965);the results of the calibration curve and the H-L goodness-of-fit test showed that the difference between the probability predicted by the model of the column and the actual probability of the line graph was not statistically significant(P>0.05).Conclusions The incidence of pressure ulcer during anesthesia surgery in elderly patients is relatively high,which is mainly affected by the patient's age,BMI,smoking history and other factors.The nomograph model established according to the above factors is characterized by high accuracy and differentiation in predicting the occurrence of pressure ulcer during anesthesia surgery.
