Purpose
This study identified factors related to bowel cleanliness of colonoscopy examinees.
Methods
From December 2, 2020 to January 21, 2021, we surveyed 152 participants who underwent colonoscopy at a university hospital at B City. The questionnaires included participants characteristics, social cognitive determinants (knowledge on bowel preparation, severity and susceptibility for colon cancer as perceived threat, self-efficacy, and social support), and compliance with bowel preparation. For data analysis, SPSS/WIN 21.0 and AMOS 22.0 statistical programs were used. Descriptive statistics, an independent t-test, one way ANOVA, Pearson correlation coefficient, and path analysis were utilized.
Results
Participants’ knowledge level on bowel preparation was 8.49±1.57; severity, 18.49±4.43; susceptibility, 12.55±4.10; self-efficacy, 41.92±9.28; social support, 24.90±4.84; compliance with bowel preparation, 9.26±1.81; and degree of bowel cleanliness, 6.05±1.71. Factors influencing the compliance with bowel preparation included self-efficacy (β=.27, p=.007), knowledge on bowel preparation (β=.23, p=.005), marital status (β=.19, p=.048), social support (β=.17, p=.030), and age (β=-.16, p=.007). The factor directly affecting bowel cleanliness was compliance with bowel preparation (β=.17, p=.043). Indirectly affecting factors were self-efficacy (β=.05 p=.021), knowledge on bowel preparation (β=.04, p=.022), social support (β=.03, p=.026), marital status (β=.03, p=.034), and age (β=-.03, p=.018).
Conclusion
Bowel cleanliness of colonoscopy examinees can be improved by enhancing compliance with bowel preparation. Future studies should examine the effects of strategies that concern self-efficacy, knowledge on bowel preparation, social support, marital status and age on compliance with bowel preparation.

PURPOSE
The purpose of this study was to evaluate the effects of a colonoscopy simulation program on knowledge and clinical performance among nursing students.
METHODS
The program consisted of a scenario with three objectives: health assessment, nursing before/after colonoscopy and emergency care for bleeding following the colonoscopy. A nonequivalent control group pretest-posttest design was used. The sample was 149 nursing students recruited from H University in G city from August, 2013 to December, 2014. The treatment group (n=71) received the simulation and the comparison group (n=78) received the usual lecture program. Data were analyzed using descriptive statistics, chi2 test, t-test and repeated measure ANOVA using the SPSS/WIN 20.0 program.
RESULT
Participants in the treatment group had significantly increased reported scores on both knowledge and clinical performance.
CONCLUSION
Results indicate that the simulated program is a useful strategy for improving knowledge and clinical performance among nursing students. The development of simulation practice programs in a variety of fields are needed in order to promote the practical competence of nursing students.

PURPOSE
This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction.
METHODS
The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming 2 liter of PEG solution twice, or a whole-dose group(n=30), consuming 4 liter of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS.
RESULTS
The participants who did not completely consume 4 liter of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups.
CONCLUSION
Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.
