Risk Score for Inadequate Bowel Cleansing

Maximizing rates of adequate bowel preparation improves detection at colonoscopy, increases procedural efficiency, and saves costs of repeat procedures.

In the current study, investigators evaluated predictors of inadequate bowel preparation using data on 1331 colonoscopies performed in four European centers. The overall rate of inadequate preparation was 12.9%. Independent predictors were American Society of Anesthesiologists (ASA) risk score ≥3, use of tricyclic antidepressants or opioids, diabetes, chronic constipation, history of abdominal and/or pelvic surgery, history of inadequate preparation, and current hospitalization. A prediction scale was developed and validated. Predictive factors were assigned points, as follows: use of tricyc…
