For the study, researchers conducted a retrospective analysis of screening colonoscopies performed by attending GI physicians between Aug. 2003 and Aug. 2005 at University of North Carolina Hospitals. Polyp detection rates and adenoma detection rates were both measured by time of day and shift type.
Results from the study showed polyp detection rate for colonoscopies starting before 9 a.m. was 48.6 percent, compared to 34 percent for colonoscopies that started at 4:00 p.m. Each hour of the day that passed was associated with reduced rates of polyp detection. Additionally, polyp detection rates were lower in the last 1.5 hours of any shift, no matter time of day, compared to the first 1.5 hours of any shift.
