Abstract
Background:colonoscopy is an important diagnostic and therapeutic tool for various conditions
affecting the colon, rectum and terminal ileum. Bowel preparation is one of the key quality
indicators among others. Suboptimal bowel preparation will significantly affect safety and
diagnostic yield of the procedure. To date there is no adequate information regarding the quality
and outcome of colposcopy preparation as well as predictors of sub optimal preparation in our
set up.
Aim: -The main objective of this study wastodetermine the proportionand predictors of
suboptimal bowel preparation among patients who undergone elective colonoscopy at TASH.
Methods: -A prospective cross-sectional study was conducted on 282 elective colonoscopies
done at TASH from March, 2023 to August 30, 2023 G.C.After informed
consent,interviewer administered structured questioner was used to collect data by a trained
interviewer. The edoscopist assessed the quality of preparation using Aronchick scale. The
collected data was cleaned, checked for completeness, compiled, entered in to Epidata
andexported to SPSS 26 for analysis. Bivariate and multivariable logistic regression analysis was
conducted to identify determinants of suboptimal colonic preparation. P value< 0.05 was taken
as significant.
Result:-Suboptimal colonic preparation was observed in 45% of the cases with 15.2% procedure
cancelation rate attributable to inadequate colonic preparation. On multivariate analysis, age
more than 60 years and non-adherence to the recommended dose of castor oil were predictors of
suboptimal colonic preparation while short telephone call a day before the start of preparation
and taking anti diabetic medication where negative predictors of suboptimal colonic preparation.
Conclusion: -This study revealed unacceptably high proportion of suboptimal bowel preparation
and procedure cancellation rate. Clinical variables independently associated with quality of
preparation include; old age, adherence to preparation regimen, anti-diabetic medication intake
and telephone counseling. Therefore intervention targeting these predictors should be designed
to improve quality of pre –colonosopic bowel preparation.
