Do faculty intensivists have better outcomes when caring for patients directly in a closed ICU versus consulting in an open ICU?

Background: Intensivists have been associated with decreased mortality in several studies, but in one major study, centers with intensivist-staffed units reported increased mortality compared with controls. We hypothesized that a closed unit, in which a unit-based intensivist directly provides and coordinates care on all cases, has improved mortality and utilization compared with an open unit, in which individual attendings and consultants provide care, while intensivists serve as supervising consultants.

Methods: We undertook the retrospective study of outcomes in 2 intensive care units (ICUs)-a traditional open unit managed by faculty intensivists and a second closed unit overseen by the same faculty intensivists who coordinated the care on all patients in a large community hospital.
