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
