Comparative StudyInfluence of nosocomial infection on mortality rate in an intensive care unit.
To assess the impact of nosocomial infection on the mortality rate in an intensive care unit (ICU). ⋯ Nosocomial infection increases the risk of death. The effect is stronger in younger and less severely ill patients.

ReviewObjective data and quality assurance programs. Current and future trends.
As CCM has grown, the diversity of ICU patients, as well as that of ICU organization and structure, has grown. This growth has led to numerous questions regarding health care delivery in the ICU. These questions contributed to the development of systems that objectively evaluate the quality of health care delivery in ICUs. ⋯ The SCCM data suggest two possible alternatives, not necessarily exclusive of each other: (1) A large percentage of ICUs may be obligated to undergo structural changes in the near future. (2) Regionalization of critical care, already present, may continue. Certain rural areas may find it more expedient to send the most critically ill patients to tertiary centers in nearby cities, as opposed to a wholesale upgrading of the delivery of care in their own ICUs. Ultimately, all hospitals will be obligated to provide patients access to the highest quality of critical care.

Factors related to multiple organ system failure and mortality in a surgical intensive care unit.
We retrospectively studied the relative contribution of factors related to the extent of multiple organ system failure (MOSF) and mortality, using multivariate methods to account for the interactions between studied factors, in 538 consecutive patients admitted to a surgical intensive care unit during a 1-year period. MOSF (MOSF score > or = 5) occurred in 88 (16%) of patients. Multiple linear regression selected advancing age, malnutrition, APACHE II score, shock and coma on admission, number of blood transfusions, use of H2 receptor antagonists or antacids, bacteraemia and intra-abdominal infection as independent factors related to the MOSF score. ⋯ Advancing age, malnutrition, shock and coma on admission, transfusion requirement and use of H2 receptor antagonists or antacids may impair host defences of the gastrointestinal tract and enhance the vulnerability for invasive infection, thereby aggravating the severity of existing MOSF. Together with the predominance of Enterobacteriaceae in infected patients, these results suggest that translocation of intestinal bacteria and endotoxin may be important in the evolution and perpetuating the MOSF syndrome. Our results may be useful in devising strategies to prevent or limit the evolution of MOSF and to improve survival in patients with critical illness.

Pretransport Pediatric Risk of Mortality (PRISM) score underestimates the requirement for intensive care or major interventions during interhospital transport.
To test the hypothesis that a pretransport Pediatric Risk of Mortality (PRISM) score underestimates the requirement for both intensive care and interventions during pediatric interhospital transport. ⋯ PRISM scores determined before interhospital transfer of pediatric patients underestimated the requirement for intensive care and the performance of major interventions in the pretransport setting. Many patients with low PRISM scores required intensive care on admission to the receiving hospital and major interventions during the transport process, and, therefore, were not at "low risk" for clinical deterioration. The PRISM score should not be used as a severity of illness measure or triage tool for pediatric interhospital transport.

Advancements in techniques of medical technology have made it possible to postpone death, which, in many situations, amounts to nothing more than a protracted process of dying rather than a prolonging of life. This, together with the fact that these techniques are prohibitively expensive has brought to the fore difficult and extremely uncomfortable problems in medical ethics, especially with regard to who should have and who should not have high technology medical treatment. ⋯ Normally it is imperative that individuals make their own autonomous decisions in respect of medical treatment but there are times when consent is of secondary importance and when autonomy must of necessity be limited. However, information concerning medical decisions in intensive care should always be freely available to patients and their surrogates.
