Multicenter StudyGeriatric Experience Following Cardiac Arrest at Six Interventional Cardiology Centers in the United States 2006-2011: Interplay of Age, Do-Not-Resuscitate Order, and Outcomes.
It is not known if aggressive postresuscitation care, including therapeutic hypothermia and percutaneous coronary intervention, benefits cardiac arrest survivors more than 75 years old. We compared treatments and outcomes of patients at six regional percutaneous coronary intervention centers in the United States to determine if aggressive care of elderly patients was warranted. ⋯ Elderly patients were more likely to have do-not-resuscitate orders and to undergo withdrawal of life support. Age was independently associated with outcome only when correction for do-not-resuscitate status was excluded, and functional outcomes of elderly survivors were similar to younger patients. Exclusion of patients more than 75 years old from aggressive care is not warranted on the basis of age alone.

Randomized Controlled Trial Multicenter StudyIncidence and Outcomes Associated With Early Heart Failure Pharmacotherapy in Patients With Ongoing Cardiogenic Shock.
Guidelines recommend β-blockers and renin-angiotensin-aldosterone system blockers to improve long-term survival in hemodynamically stable myocardial infarction patients with a reduced left ventricular ejection fraction. The prevalence and outcomes associated with β and renin-angiotensin-aldosterone system blocker therapy in patients with ongoing cardiogenic shock is unknown. ⋯ The administration of β or renin-angiotensin-aldosterone system blockers is common in North America and Europe in patients with myocardial infarction and cardiogenic shock prior to cardiogenic shock resolution. This therapeutic practice was independently associated with higher 30-day mortality, although a statistically significant difference was only observed in the subgroup of patients administered β-blockers.

Review Meta AnalysisMacrolides and Mortality in Critically Ill Patients With Community-Acquired Pneumonia: A Systematic Review and Meta-Analysis.
Some studies suggest better outcomes with macrolide therapy for critically ill patients with community-acquired pneumonia. To further explore this, we performed a systematic review of studies with mortality endpoints that compared macrolide therapy with other regimens in critically ill patients with community-acquired pneumonia. ⋯ In observational studies of almost 10,000 critically ill patients with community-acquired pneumonia, macrolide use was associated with a significant 18% relative (3% absolute) reduction in mortality compared with nonmacrolide therapies. After pooling data from studies that provided adjusted risk estimates, an even larger mortality reduction was observed. These results suggest that macrolides be considered first-line combination treatment in critically ill patients with community-acquired pneumonia and support current guidelines.

Multicenter StudyAssociation Between Hyperoxia and Mortality After Stroke: A Multicenter Cohort Study.
To test the hypothesis that hyperoxia was associated with higher in-hospital mortality in ventilated stroke patients admitted to the ICU. ⋯ In ventilated stroke patients admitted to the ICU, arterial hyperoxia was independently associated with in-hospital death as compared with either normoxia or hypoxia. These data underscore the need for studies of controlled reoxygenation in ventilated critically ill stroke populations. In the absence of results from clinical trials, unnecessary oxygen delivery should be avoided in ventilated stroke patients.

Delirium in the ICU and Subsequent Long-Term Disability Among Survivors of Mechanical Ventilation.
Survivors of critical illness are frequently left with long-lasting disability. The association between delirium and disability in critically ill patients has not been described. We hypothesized that the duration of delirium in the ICU would be associated with subsequent disability and worse physical health status following a critical illness. ⋯ In the setting of critical illness, longer delirium duration is independently associated with increased odds of disability in activities of daily living and worse motor-sensory function in the following year. These data point to a need for further study into the determinants of functional outcomes in ICU survivors.
