To assess risk factors affecting viability and analyze the effects of mechanical ventilation (MV) on neonatal outcome and resource use among extremely premature infants. ⋯ Although recommendations to initiate or forgo MV for extremely premature infants have often focused on 1 factor (birth weight or gestational age), multiple factors should be considered. Other factors being equal, our analyses support use of MV for females at a minimum birth weight approximately 100 g lower than that for males. The current diagnosis related group reimbursement system can be expected to compromise resources for 501- to 800-g infants who would benefit from MV. Such care entails considerable resource use, although the cost per life-year gained is likely to be considerably less than that for many adults given intensive care. Our findings can be used to facilitate more appropriate treatment decisions, determine adequate resources, and better inform the debate about the benefits and burdens of intensive care for extremely premature newborns.

Comparative Study
Racial variation in predicted and observed in-hospital death. A regional analysis.
To compare observed, predicted, and risk-adjusted hospital mortality rates in white and African-American patients and to determine whether, as prior studies suggest, African-American patients would have higher predicted risks of death and similar or higher risk-adjusted mortality. ⋯ Contrary to our a priori hypotheses, predicted risks of death and risk-adjusted mortality rates were generally lower in African-American patients. Our finding of lower predicted risk may reflect racial differences in hospital admission practices or in access to outpatient care. However, our findings suggest that, once hospitalized, African-American patients attained similar or better outcomes, as measured by an important measure--hospital mortality.

To determine the role of advance directives in decisions to withdraw chronic dialysis in the United States, Germany, and Japan. ⋯ There is a high prevalence of advance directives among American dialysis patients, and such directives frequently play a role in decision making. German and Japanese nephrologists appear willing to follow advance directives, but the low prevalence of such directives limits the frequency of their use.

To determine the applicability to emergency department (ED) clinical practice of a nationally disseminated practice guideline on the disposition of patients with a diagnosis of unstable angina, and to determine the potential impact of the guideline on hospital admissions and demand for intensive care beds. ⋯ Although the guideline was intended to reduce hospitalization by identifying a low-risk group, the small size of this group among ED patients suggests that little reduction in hospitalization can be expected. Indeed, the guideline may increase demand for the limited number of intensive care beds to accommodate patients with unstable angina considered high-risk but currently placed elsewhere. These results emphasize the need to use empiric data from target clinical settings to assess the likely actual impact of guidelines on clinical care prior to national dissemination.
