In 2001, the Society of Critical Care Medicine published practice model guidelines that focused on the delivery of critical care and the roles of different ICU team members. An exhaustive review of the additional literature published since the last guideline has demonstrated that both the structure and process of care in the ICU are important for achieving optimal patient outcomes. Since the publication of the original guideline, several authorities have recognized that improvements in the processes of care, ICU structure, and the use of quality improvement science methodologies can beneficially impact patient outcomes and reduce costs. Herein, we summarize findings of the American College of Critical Care Medicine Task Force on Models of Critical Care: 1) An intensivist-led, high-performing, multidisciplinary team dedicated to the ICU is an integral part of effective care delivery; 2) Process improvement is the backbone of achieving high-quality ICU outcomes; 3) Standardized protocols including care bundles and order sets to facilitate measurable processes and outcomes should be used and further developed in the ICU setting; and 4) Institutional support for comprehensive quality improvement programs as well as tele-ICU programs should be provided.

A 19-yr-old woman developed ketoacidosis 7 wk after the delivery of her first child. Despite breast feeding, she had been on a weight reduction diet resulting in a loss of 12 kg/body wt. With the development of a urinary tract infection, the patient became dehydrated and was found to be in ketoacidosis (arterial pH was 7.25 and PaCO2 was 17 mm Hg). The patient did not use alcohol and was nondiabetic. Therapy with adequate calories, intravenous fluids, and an appropriate antimicrobial agent resulted in prompt normalization of the laboratory abnormalities and resolution of the patient's symptoms. The hypothesis is advanced that the postpartum status of the patient put her at particular risk for development of ketoacidosis and that this may represent the first reported episode of "bovine ketosis" in a human.
