Emerging trends in ICU management and staffing.

It is likely that greater on-site intensivist coverage in critical care units will be observed in the future. Regionalization of critical care services will make this a financial reality because this level of expertise cannot realistically be provided to all hospitals. Perhaps units above a certain size will warrant this level of coverage and smaller community hospitals will transfer patients in need of a very high level of service, which can be provided only by intensivists on site. Community hospitals may rely on specially trained nurse practitioners or physician assistants to provide more on-site coverage during off hours. As technology advances, telemedicine will play a greater role in providing intensivist coverage to ICUs during off hours or to community hospitals in remote areas. Advanced technology and reorganization of critical care services offer opportunities for creative and nontraditional ways to deliver improved care to patients.
