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.

Withdrawal or withholding of life-sustaining therapies precedes most deaths in the modern ICU. As goals of care for critically ill patients change from curative to palliative, this transition often occurs abruptly, but a slower more staggered approach may also be used. One such approach is "no escalation of care", often the first step in this transition at the end-of-life. We aimed to determine the prevalence of no escalation of care designation for ICU decedents and identify which interventions are involved. ⋯ No escalation of care designation occurs in a significant proportion of ICU decedents shortly before death. Some interventions are more likely to be limited than others using a no escalation of care approach.

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 AnalysisTherapeutic Hypothermia and the Risk of Infection: A Systematic Review and Meta-Analysis.
Observational studies suggest that infections are a common complication of therapeutic hypothermia. We performed a systematic review and meta-analysis of randomized trials to examine the risk of infections in patients treated with hypothermia. ⋯ The available evidence, subject to its limitations, strongly suggests an association between therapeutic hypothermia and the risk of pneumonia and sepsis, whereas no increase in the overall risk of infection was observed. All future randomized trials of hypothermia should report on this important complication.

Multicenter StudyTiming of Limitations in Life Support in Acute Lung Injury Patients: A Multisite Study.
Substantial variability exists in the timing of limitations in life support for critically ill patients. Our objective was to investigate how the timing of limitations in life support varies with changes in organ failure status and time since acute lung injury onset. ⋯ Persistent organ failure is associated with an increase in the rate of limitations in life support independent of the absolute magnitude of Sequential Organ Failure Assessment score, and this association strengthens during the first weeks of treatment. During the first 5 days after acute lung injury onset, limitations were significantly more common in medical ICUs than surgical ICUs.
