Resident fatigue in 2010: where is the beef?

Area of Science:

• Medical Education
• Resident Duty Hours
• Task Performance Simulation

Background:

• Accreditation Council for Graduate Medical Education (ACGME) duty hour limits for postgraduate year-1 residents effective July 1, 2011, mandate a maximum of 16 hours of call.
• Prior research indicated potential decrements in post-call task performance.
• This study aimed to assess if these performance decrements persisted in 2010 and identify specific time points of occurrence.

Purpose of the Study:

• To evaluate resident task performance during a 24-hour call period.
• To determine if decrements in performance exist and at what time intervals they occur.
• To inform future resident duty hour regulations.

Main Methods:

• Fourteen residents participated in the study.
• Residents completed 4 simulator tasks across 5 separate call periods.
• Task performance was assessed at 4 time intervals (T0, T12, T18, T24) over 24 hours, followed by a post-call survey.

Main Results:

• A trend towards decreased task completion time was observed over the 24-hour call.
• Task accuracy and efficiency were generally preserved.
• Some residents demonstrated improved performance, with minimal correlation between perceived fatigue and actual performance.

Conclusions:

• No decrease in junior or senior resident task performance was found over a 24-hour call.
• The study's findings do not support the 2011 ACGME maximum duty hour length of 16 hours.
• Resident performance may not be negatively impacted by longer call durations within a 24-hour period.
