Potential reduction in mortality rates using an intensivist model to manage intensive care units.
Because of evidence suggesting that outcomes are better in "intensivist-model" intensive care units (ICUs), the Leapfrog Group's hospital safety standards propose that ICUs be managed by critical care physicians (intensivists) who work exclusively in the ICU. ⋯ In the nine studies that met our selection criteria, relative reductions in mortality rates associated with intensivist-model ICUs ranged from 15% to 60%. On the basis of the most conservative estimate of effectiveness (15% reduction), full implementation of intensivist-model ICUs would save approximately 53,850 lives each year in the United States. CAUTIONS: Given the large number of ICU patients and their high baseline risks, even modest reductions in mortality rates would save many lives. Because of potential constraints related to the workforce and other resources, the feasibility of fully implementing intensivist-model ICUs nationwide is uncertain.
