Abstract： AIM To evaluate the effect of the clinical pathway for colorectal polyps and try to improve its effect.METHODS The clinical data of patients with colorectal polyps treated at the Department of Gastroenterology of the First Hospital of Jilin University were retrospectively analyzed.Patients with colorectal polyps treated via the clinical pathway were included in a clinical pathway group and the others in a control group.The hospitalization cost,medicine cost,hospitalization time,and satisfaction degree of the two groups were compared.The PDCA cycle theory was applied to the management of the clinical pathways,and then the trend of changes in evaluation indexes was assessed:RESULTS The hospitalization cost,medicine cost,and duration of hospitalization in the clinical pathway group were significantly lower than those in the control group (P ＜ 0.01),but the degree of patients' satisfaction was significantly higher than that in the control group (P ＜ 0.01).The evaluation indicators including length of stay,preoperative hospital stay,total cost,bed fee,special care cost and medicine cost showed a gradual downward trend after the application of the PDCA cycle theory to the clinical pathway for colorectal polyps.CONCLUSION Clinical pathway can effectively reduce hospitalization cost,shorten hospitalization days,and increase the degree of patients' satisfaction.The application of the PDCA cycle theory to the clinical pathway can result in a continuous quality improvement.
