Core Tip
Core tip: Split bowel reparation compared to single dose morning preparation resulted in a better bowel cleansing using the Ottawa Bowel Preparation Scale. The average score (± SD) using the Ottawa Scale was 6.02 ± 1.34 when morning preparation was given and 5.52 ± 1.23 when split preparation was given (P = 0.017). However, there was no statistical difference in the mean Ottawa score when the procedures were done in the afternoon with either the morning or the split preparation (6.09 vs 5.94, P = 0.756). Hence, AM only dosing is as effective as split dosing for patients scheduled for a colonoscopy in the afternoon.
