RationaleAround-the-clock intensivist presence in intensive care units (ICUs) has been promoted as necessary to optimize outcomes. Little data have addressed how it affects the multiple stakeholders in such care.ObjectivesTo assess effects of around-the-clock intensivist presence on intensivists, patients, families, housestaff, and nurses.MethodsThis 32-week, crossover pilot trial of two intensivist staffing models, performed in two Canadian ICUs, alternated 8-week blocks of two staffing models: the standard model, where one intensivist worked for 7 days, taking night call from home; and the shift work model, where one intensivist worked 7 day shifts, while other intensivists remained in the ICU at night.Measurements And Main ResultsSurveys scaled from 0-100 points assessed outcomes for 24 intensivists (primary outcome: burnout); 119 families (satisfaction); 74 nurses (satisfaction with collaboration and communications, role conflict); and 34 housestaff (autonomy, supervision, and learning opportunities). Outcomes for 501 patients included mortality, length of stay, and resource use. Intensivists doing shift work experienced less burnout (-6.9 points; P = 0.04). Adjusted hospital mortality (odds ratio, 1.22; P = 0.44), ICU length of stay (-6 h; P = 0.46), and family satisfaction (0.9 points; P = 0.79) did not differ between staffing models. Under shift work staffing, nurses reported more role conflict (9 points; P < 0.001), whereas nighttime housestaff reported less autonomy, more supervision, but no difference in learning opportunities.ConclusionsShiftwork staffing was better for intensivists and most were receptive once they had experienced it. Although there were no evident negative outcomes for patients or families, further evaluation is needed to clarify how around-the-clock intensivist staffing influences the various stakeholders in ICU care, given power considerations in this study.
