Impact of resident duty hour limits on safety in the intensive care unit: a national survey of pediatric and neonatal intensivists.

OBJECTIVE

Resident duty-hour regulations potentially shift the workload from resident to attending physicians. We sought to understand how current or future regulatory changes might impact safety in academic pediatric and neonatal intensive care units.

DESIGN

Web-based survey.

SETTING

U.S. academic pediatric and neonatal intensive care units.

SUBJECTS

Attending pediatric and neonatal intensivists.

INTERVENTIONS

We evaluated perceptions on four intensive care unit safety-related risk measures potentially affected by current duty-hour regulations: 1) attending physician and resident fatigue; 2) attending physician workload; 3) errors (self-reported rates by attending physicians or perceived resident error rates); and 4) safety culture. We also evaluated perceptions of how these risks would change with further duty-hour restrictions.

MEASUREMENTS AND MAIN RESULTS

We administered our survey between February and April 2010 to 688 eligible physicians, of whom 360 (52.3%) responded. Most believed that resident error rates were unchanged or worse (91.9%) and safety culture was unchanged or worse (84.4%) with current duty-hour regulations. Of respondents, 61.9% believed their own work-hours providing direct patient care increased and 55.8% believed they were more fatigued while providing direct patient care. Most (85.3%) perceived no increase in their own error rates currently, but in the scenario of further reduction in resident duty-hours, over half (53.3%) believed that safety culture would worsen and a significant proportion (40.3%) believed that their own error rates would increase.

CONCLUSIONS

Pediatric intensivists do not perceive improved patient safety from current resident duty-hour restrictions. Policies to further restrict resident duty-hours should consider unintended consequences of worsening certain aspects of intensive care unit safety.
