Physician and nurse practitioner roles in emergency, trauma, critical, and intensive care

•MDs report that MDs are their team leaders in most circumstances; NPs are less likely to indicate that MDs lead their teams.•Less than half of MD or NP clinicians agree that they experience excellent team work in their units.•Significantly more MDs than NPs agree their role in the care team is clear. The delivery of emergency, trauma, critical, and intensive care services requires coordination among all members of the care team. Perceived teamwork and role clarity may vary among physicians (MDs) and nurse practitioners (NPs). To examine differences in perceived roles and responsibilities of NPs and MDs practicing in emergency, trauma, critical, and intensive care. Secondary Analysis of the National Survey of Emergency, Intensive, and Critical Care Nurse Practitioners and Physicians, a cross-sectional national survey of clinicians. Mail survey of randomly selected stratified cross-sectional samples of MDs and NPs drawn from national lists of clinicians in eligible specialties working in emergency, trauma, intensive, and critical care units in the United States. 814 clinicians (351 NPs and 463 MDs) were recruited from national by postal mail survey. Our initial sample included n = 2,063 clinicians, n = 1,031 NPs and n = 1,032 MDs in eligible specialties. Of these, 63.5% of NPs and 70.1% of MDs completed and returned the survey excluding those who were ineligible due to lack of current practice in a relevant specialty. NPs in ICU/CCU are more likely to be female and report working fewer hours than do MDs and provide direct care to more patients. 55% of NPs and 82% of MDs agree that their individual role in their unit is clear (p < .001); 34% of MDs and 42% of NPs agree that their unit is an example of excellent team work among professionals (p = 0.021); 41% of MD and 37% of NP clinicians (p = 0.061) agree that their teams are “prepared to provide outstanding care in a crisis or disaster.” Perceived role clarity was significantly associated with increased perceptions of excellent teamwork and disaster preparedness. At the time of this survey, and majority of NPs and MDs working in emergency, critical and intensive care did not agree that their teams were prepared for a crisis or disaster. Leaders of health organizations should encourage teamwork and professional role clarity to assist units to perform effectively in emergency and disaster preparedness.
