title: Critical-care medicine and the acute-care laboratory.
abstract: Critical-care medicine today is practiced by anesthesiologists, internists, pediatricians, and surgeons. Outcome from today's management of critically ill patients is very good, yet associated costs are very high. Over one-half of the hospital costs of critically ill patients emanates from the intensive-care unit (ICU), although the ICU stay accounts for less than 20% of their time in the hospital. Outside of the operating room, the ICU is the most expensive location for patient care in the hospital, and laboratory tests are the most expensive single item. Plans for cost containment should incorporate the following: more effective data management, education of practitioners about appropriateness and costs of tests, conversion from laboratory measurements to appropriate in vivo and ex vivo measurements, and real-time utilization assessment. To provide high-quality, cost-effective critical care in the future, laboratorians and clinicians must work together today to meet the challenges of technology, data management, and staff education.
