Tired Physicians Less Accurate in Detecting Adenomas

The effectiveness of any medical procedure in preventing disease or making an accurate diagnosis depends largely on the skill, effectiveness, and performance of the physician. In a novel research project, investigators compared the results of colonoscopies performed in the morning versus the afternoon. Interestingly, the procedures performed in the morning were significantly more accurate than those done in the afternoon. Furthermore, there was an independent trend toward declining accuracy throughout the day. Researchers concluded that physician fatigue, which increases as the day progresses, impairs detection rates.

PositiveTip: For greatest accuracy in colonoscopies, ask for a morning appointment when your physician is more rested! This may hold true for other procedures and tests as well.
