title: Intensivists at night: putting resources in the right place.
abstract: During the past 50 years, caring for the critically ill has become increasingly complex and the need for an intensivist has become more evident. Management by intensivists has become a quality indicator for many ICUs. Numerous small studies have demonstrated the beneficial effect of intensivists on outcomes in the critically ill, and some clinicians have advanced the argument that a night-time intensivist is essential for the care of critically ill patients. In response, many institutions have hired full-time intensivists for both day and night coverage in the ICU. Two recent studies have been conducted that make a compelling argument for redirecting funding of night-time intensivists to areas of greater need in health care. In a retrospective analysis of a large database that involved more than 65,000 patients, no benefit of night-time intensivists could be found in ICUs where care is managed by intensivists during the day. Only in ICUs where management by intensivists is not mandated could a beneficial impact on mortality be found. The second study, a randomized controlled trial, evaluated the effect of night-time intensivists on length of stay, mortality, and other outcomes and was a negative trial. In this methodologically rigorous trial, there was no difference in outcomes between the intensivist and control group, which consisted of in-house resident coverage at night with availability by telephone of fellows and intensivists. These two robust studies clearly suggest that night-time intensivists do not improve mortality in ICUs managed by intensivists during the day. Though possibly beneficial in low-intensity environments, the widespread drive to add night-time intensivist coverage may have been premature.
