To explore the case management model for improving self-care ability of colostomy patients and mastering relevant knowledge, improving the subjective feeling of life for the colostomy patients, and improving the effect of the nursing service satisfaction.

Seventy-eight patients were divided into observation group and control group by random grouping method. Thirty-nine cases were in the observation group and 39 cases were in the control group. The observation group used the case management model to nurse the patients, the control group were nursing according to the postoperative rectal cancer routine nursing process, health education and rehabilitation guidance.

Colostomy self-care status, self-care skills and mastering of colostomy nursing knowledge of the observation group after 1 week, 1 month, 3 months were better than that in control group (self-care status: χ²=8.057, P=0.045; χ²=18.831, P<0.001; χ²=13.484, P=0.004; self-care skills: t=12.093, P=0.001; t=16.62, P<0.001; t=15.418, P<0.001), the subjective feeling aspect of colostomy life of the observation group of patients in the hospital after three months also scored higher than the control group (t=5.198, P=0.007; t=4.514, P<0.001).

Through the case management model, the patients with permanent colostomy can obviously improve themselves with self-care skills, master the colostomy nursing knowledge, improve the subjective feeling of colostomy patients, improve patient satisfaction to nursing service at the same time and improve the relationship between nurses and patients.
