Impact of the Four Seasons on Bowel Cleansing Quality Prior to Colonoscopy

Bakirkoy Dr. Sadi Konuk Research and Training Hospital1,000 enrolled

Overview

Patients scheduled to undergo elective colonoscopy will be evaluated in this observational study. No additional medications, interventions, or diagnostic procedures beyond standard clinical practice will be administered. The primary objective of the study is to investigate whether the quality of bowel preparation prior to colonoscopy varies according to seasonal differences. Bowel cleansing quality will be assessed during the colonoscopy procedure using standard evaluation criteria. The quality of bowel preparation will be compared across different seasons to determine the potential impact of seasonal variation on bowel cleansing adequacy prior to elective colonoscopy.

This study is designed as an observational analysis of patients undergoing elective colonoscopy. All participants will receive standard bowel preparation according to routine clinical practice, and no additional medications, interventions, or diagnostic tests will be introduced as part of the study protocol. The primary aim of the study is to evaluate whether seasonal variation influences the quality of bowel preparation prior to colonoscopy. Adequate bowel cleansing is a critical factor affecting diagnostic accuracy, procedural efficiency, and patient outcomes during colonoscopy. Environmental factors, including seasonal changes, may influence patient compliance, hydration status, and dietary habits, which could potentially affect bowel preparation quality. Bowel cleansing quality will be assessed during the colonoscopy procedure using established bowel preparation assessment criteria. Patients will be categorized according to the season in which the colonoscopy is performed, and bowel preparation quality will be compared among these seasonal groups. The findings of this study are expected to provide insight into the potential impact of seasonal variation on bowel preparation quality and may contribute to optimizing colonoscopy preparation strategies in clinical practice.

Interventions

Routine Colonoscopy Bowel Preparation Quality AssessmentOTHER

This is an observational and non-interventional study. No additional medications, diagnostic tests, or procedures are administered to the patients beyond routine clinical practice. The intervention consists solely of assessing bowel preparation quality during routinely performed elective colonoscopy procedures and evaluating its association with seasonal variation.

Outcomes

Primary Outcomes

Bowel Preparation Quality During Elective Colonoscopy

Bowel preparation quality assessed during elective colonoscopy using the Boston Bowel Preparation Scale (BBPS), which ranges from 0 to 9, with higher scores indicating better bowel cleansing quality. Bowel preparation quality scores will be compared across different seasons.

Time frame: During the colonoscopy procedure
