The objective of this descriptive research was to examine the outcomes of a bowel preparation by assessing
knowledge, behavior and cleanliness of the colon in subjects undergoing a colonoscopy. The Donabedian Model was used as a research framework. The purposive samples were 94 persons undergoing colonoscopy, prepared at Out Patient Department of one tertiary hospital. Data were collected using personal data information sheet, knowledge test and questionnaires concerning behaviors and bowel cleanliness. Descriptive statistics, One sample t-test and chi-square were used to analyzed the data.
The findings showed that most of the sample had a high level of knowledge and behavior and significantly
higher than standard criteria at 80% (p<.01). Most of the participants evaluated bowel cleanliness as watery stool, that did not differ from the physician’s evaluation (p=.386). The results confirm the quality of outcomes. However, approximately 25 percent needed additional enema and/or PEG. Factors related to bowel preparation of this group should be explored.
