Review[Rational distribution of resources in intensive medicine. Analysis of admission and discharge criteria at intensive care units].
Cost-containment in health care has become a major issue in today's practice of medicine. With its needs in advanced technologies and skilled personnel, intensive care is among the most expensive of all hospital activities. This fact makes the analysis of indications for intensive care unit admission, as well as early discharge, of paramount importance: patients who are not likely to benefit from intensive care are at the extremes of disease severity, since low-risk patients are not ill enough to need ICU admission and high-risk patients have a very high mortality, irrespective of intensive care treatment. In this paper we discuss, based on published evidence, the formulation of recommendations for admission and early discharge from ICUs, and also present the Society of Critical Care Medicine guidelines, on this subject.

Considerable attention has focused on describing ethical issues that critical care nurses face in their practice: however, less attention has been directed at describing the process of ethical decision-making. Systematic research linking aspects of ethical-decision making and stress is lacking. ⋯ Sixty-one critical care nurses completed the Nurse's Ethical Decision Making--ICU Questionnaire and the Health Professions Stress Inventory. Findings revealed that nurses who selected the patient advocacy model had significantly higher nurse autonomy scores, that perceived anxiety had a negative association with nurse autonomy, and that workplace restrictions and stress were related.

Case ReportsNeutralizing ageism in critical care via outcomes research.
Ageism, as a mind-set, amplifies a belief that intensive care for the elderly is ineffectual. However, there are little data to support the notion that advanced chronological age alone predicts unfavorable outcomes in response to intensive care. A lack of outcome data, combined with ageism, may place older patients at risk for rationing of intensive care. ⋯ However, as pressure to reduce health care costs increases, critically ill elderly patients may be targeted for rationing. In this context, outcomes research involving elderly populations is crucial. The purpose of this report is to explicate the risk of ageism in the delivery of intensive care and to describe methods for implementing outcomes assessment for critically ill elderly patients as an essential element in a continuum of care.

In an investigation of infection control methods for respirator systems in 89 randomly selected German intensive care units as a part of the NIDEP study (Nosocomial Infections in Germany--Surveillance and Prevention), it was found that respirator systems were exchanged daily in about 50% of the intensive care units. However, Craven et al. found that changing circuits (including tubing and exhalation valve and the attached humidifier) every 24 h rather than every 48 h was independently associated with the occurrence of nosocomial pneumonia. On the basis of these results and recent studies, the current situation in the literature was analyzed in order to make recommendations for exchanging ventilator circuits. ⋯ The available studies show clear advantages of not routinely exchanging the ventilator circuit, including tubing, exhalation valve and the attached humidifier, more often then every 7 days for an individual patient. Based on these findings, the current practice in most German intensive care units should be reevaluated.
