A colostomy is an artificial opening in the abdominal wall that is made during surgery, which changes normal body function to allow stools to pass after a disease or injury. The study was planned to assess the effectiveness of structured teaching programme on patient’s knowledge on self care management of colostomy in tertiary care hospitals. Experimental approach with one group pre test - post test design was used for 30 patients. Majority 46.7 % of patients belonged to the age group of 31-40 years, and 86.7% were males. The knowledge score gained by the respondents in the results shows that the mean value of knowledge in pre test was 8.63 and at post assessment was 17.1. Since, the “p” value for the test is 0.05. Structured teaching programme was highly effective to improve the knowledge score of subjects towards colostomy care.
