目的 分析基于数据包络分析(DEA)模型评估肠内营养联合加速康复用于非小细胞肺癌手术患者的效果。 方法 选取 2020 年 10 月至 2023 年 10 月期间在中山市小榄人民医院治疗的 102 例非小细胞肺癌手术患者,根据随机数字表法分为 两组,对照组 51 例采用常规干预指导,试验组 51 例采用肠内营养联合加速康复,比较两组干预效果后,再经 DEA 模型预 测,比较两组技术效益、规模效益、综合效益、规模报酬系数、有效性和规模报酬类型。 结果 试验组卧床时间、胸管留置时间、 抗生素使用时间、住院时间短于对照组(P<0. 05),总治疗费用少于对照组(P<0. 05),术后 7 d 的功能状况、情感状况、家庭状 况、生理状况、肺癌附加情况评分高于对照组(P<0. 05),术后 7 d 的第 1 秒用力呼气容积(FEV1 )、用力肺活量(FVC)、每分钟 最大通气量(MVV)、血清白蛋白(ALB)、总蛋白(TP)、血红蛋白(Hb)改善情况优于对照组(P<0. 05),术后肺部并发症发生率 (3. 92% 比 17. 65%)低于对照组(χ 2 = 4. 993,P= 0. 025)。 同时,建立 DEA 模型预测,试验组营养状况指标的技术效益值为 1 的决策单元有 32 个,综合效益 28 个,以 DEA 强有效、规模报酬固定为主。 两组营养状况指标的技术效益、综合效益存在差 异,肺功能指标的技术效益、综合效益、规模报酬系数存在差异(P<0. 05)。 结论 基于 DEA 模型评估分析,肠内营养联合加速 康复能够提高规模效率和综合效益,利用价值较高,将其用于非小细胞肺癌手术患者中效果显著,可改善术后肺功能和营养 状态,降低术后肺部并发症发生率,促进术后康复。

Objective Analyze the effectiveness of enteral nutrition combined with accelerated rehabilitation for non-small cell lung cancer patients undergoing surgery based on the DEA model. Method 102 non -small cell lung cancer surgical patients treated at Xiaolan People's Hospital in Zhongshan City from October 2020 to October 2023 were selected and randomly divided into two groups using a random number table method. The control group 51 cases received routine intervention guidance while the experimental group 51 cases received enteral nutrition combined with accelerated rehabilitation. After comparing the intervention effects of the two groups the DEA model was used to predict the technical benefits TE scale benefits SE k and comprehensive benefits OE of the two groups θ 、 The coefficient of return to scale effectiveness and types of return to scale. Result Bedtime chest tube retention time antibiotic duration and hospital stay were shorter than controls P<0. 05 total treatment cost was less P<0. 05 functional status emotional status family status physiological status and lung cancer were higher P<0. 05 FEV 1 MVV FVC Hb ALB and TP were 7 d P<0. 05 and postoperative pulmonary complications 3. 92% vs. 17. 65% were lower than controls χ 2 = 4. 993 P= 0. 025 . At the same time the DEA model was established to predict that there were 32 decision units with technical benefit value of 1 in the test group and 28 comprehensive benefits mainly DEA was mainly effective and the scale was fixed in remuneration. The technical benefits and comprehensive benefits of the two groups were different and the technical benefits comprehensive benefits and scale remuneration coefficient of the pulmonary function indicators were different P< 0. 05 . Conclusion Based on the DEA model evaluation analysis the combination of enteral nutrition and accelerated rehabilitation can improve scale efficiency and comprehensive benefits with high utilization value. Its application in non-small cell lung cancer surgery patients has significant effects improving postoperative lung function and nutritional status reducing postoperative pulmonary complications and promoting postoperative rehabilitation
