Objective To carry out the health economic evaluation between Changhai-AL-Prediction model after anterior resection for rectal cancer and the operator's decision-making preventive stoma plan in order to provide a best preventive stoma plan.Methods A prospective investigation of 200 rectal adenocarcinoma patients with low anterior resection in the First Affiliated Hospital of Naval Medical University was carried out from June 2023 to December 2023.The therapeutic effects of the two groups were compared and a decision tree model was constructed for cost-effectiveness analysis.Results The expected cost for the surgeon's decision-making group was 8 639 053.19 RMB,and the expected cost for the Changhai-AL-Prediction model after anterior resection for rectal cancer group was 7 133 715.92 RMB.The decision accuracy of the operator decision-making group is 36.5%,and the accuracy of the model decision-making group is 70.0%.The incremental cost-effectiveness ratio is-44 935.44.The cost of the model group is 44 935.44 RMB less than that of the surgeon's decision-making group for every 1%improvement in prediction accuracy.Conclusion Changhai-AL-Prediction model after anterior resection for rectal cancer can make more accurate preventive stoma decisions and has more economic advantages than the operator's decision plan.
