The Impact of Patient Education Level on Split-Dose Colonoscopy Bowel Preparation for CRC Prevention

Introduction AGA guidelines emphasize split-dose bowel preparation (BP) to ensure high-quality colonoscopy for the prevention of colorectal cancer (CRC). Split dose results in higher-quality preparation, but understanding instructions might be more difficult. Lower education levels may negatively influence BP quality. The confounding role of education level on BP quality was investigated. Methods This was a cross-sectional study of 60 patients given split-dose BP. Patients consented and were asked three Likert scale questions based on BP instructions before the procedure. Compliance was self-reported. BP adequacy and the number of adenomas were recorded. BP was characterized as adequate (excellent, good) or inadequate (fair, poor). Data was analyzed with chi-square, odds ratio, Mann-Whitney, and regression analysis. Results Thirty-one (52%) patients were high school graduates, 21 (38%) completed some college, and 6 (10%) were college graduates. College-educated patients had adequate BP (72%) more often than high school graduates (51%) (p = 0.02). Adenoma findings were not significantly different. The Likert scale mean ranks for patient understanding and reviewing of instructions were comparable between the two groups. Patient rating of scheduler explanations of the importance of following instructions was significantly better in the college group (mean ranks 2.59 and 1.83, respectively; p = 0.018). Discussion Patient education level significantly affected the success of BP. Split BP can be more complex to comprehend, and instructions should consider patient education level. Specific intervention programs should be implemented to advise patients with less education that poor preparation may result in missed advanced neoplasias and subsequent procedures.

Automated summary

The study found that patient education level significantly affected the success of bowel preparation. Split-dose bowel preparation can be more challenging to comprehend, and instructions should take into account the patient's education level. Specific intervention programs should be implemented to advise patients with lower education levels about the importance of proper preparation to prevent missed advanced neoplasias and subsequent procedures.
