The impact of prolonged continuous wakefulness on resident clinical performance in the intensive care unit: A patient simulator study*
Bibliographic record
Abstract
OBJECTIVE: To evaluate the impact of prolonged continuous wakefulness on resident performance under controlled experimental conditions. DESIGN: Experimental within-subjects comparison. SETTING: High-fidelity patient simulator. PARTICIPANTS: Twelve residents in an Internal Medicine Program at various stages of training (range, 1-35 mos). MEASUREMENTS: Performance was studied during 26 hrs of continuous wakefulness at four time points (8:00-10:00 am, 2:00-4:00 pm, 2:00-4:00 am, and 8:00-10:00 am the next day) using high-fidelity patient simulation. At each session, residents managed eight simulated dysrhythmias according to advanced cardiac life support protocols (advanced cardiac life support scenarios) and then managed a simulated critically ill patient (e.g., patient with meningitis) to test more complicated clinical decision-making (complex scenario). The frequency of previously defined major medical errors (i.e., action or inaction that likely would have resulted in significant harm in a real patient) was assessed by a scorer blinded to the time of the session. For each complex scenario, a global score between 0 and 100 was also given for overall performance. The impact of wakefulness on performance was assessed by using longitudinal mixed-effects models. RESULTS: For the complex scenarios, the mean number of errors increased from 0.92 +/- 0.90 in the first session to 1.58 +/- 0.79 in the fourth session (p = .09), and mean global score decreased from 56.8 +/- 14.6 to 49.6 +/- 12.6 (p = .02). For the advanced cardiac life support scenarios, the mean number of major errors committed in the advanced cardiac life support scenarios decreased during the study period (p = .01). However, essentially all of the improvement occurred between the first and second time points, suggesting that a substantial learning effect accounted for the findings. CONCLUSIONS: During prolonged continuous wakefulness of medical residents, clinical performance in the management of a simulated critically ill patient deteriorates. The practice of scheduling residents for extended work shifts (>24 hrs) should be reconsidered.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
