To enhance comparability in reports on survival from out-of-hospital cardiac arrest, an international task force recently developed a set of guidelines for uniform terminology, definitions, and data collection for outcome research on cardiac arrest--the Utstein style. Because the data collection recommended is limited to information available through emergency medical services systems, the potential for bias in comparisons of cardiac arrest outcomes remains. By expanding data collection to include the identification of all cases of cardiac arrest in the community, including patients who do not present for care by an emergency medical services system, a population-based approach can be achieved. We review the strengths and limitations of both emergency medical services-based and population-based data collection to assess outcomes of cardiac arrest, outline practical steps required to implement a population-based approach, and suggest that extension of the Utstein style guidelines to include all cardiac arrest cases within a defined population is needed to minimize potential bias in comparisons of cardiac arrest outcomes across communities or over time.

To determine if age, previous functional status, or acute severity of illness affect the acute and long-term mortality rates and functional status of the very elderly (> or = 85 yrs) after an ICU admission. ⋯ Within the very elderly population, acute severity of illness is the most significant predictor of mortality after an ICU admission. For most very elderly patients, surviving 1 yr after an ICU admission, there is little change in functional status.

This study assesses the effects of a status asthmaticus guideline on patient outcome and pediatrician behavior in a staff model health maintenance organization (HMO). The guidelines were drafted by an asthma specialist in the HMO and then discussed with key clinical personnel. ⋯ The medical records of pediatric patients admitted to the hospital with status asthmaticus before (N = 67) and after (N = 59) guideline development and implementation were reviewed. This study demonstrates that locally developed, treatment-specific guidelines based on scientific evidence and combined with a staff consensus process and a user-friendly protocol form can influence physician behavior and patient outcome positively.
