ReviewCritical Care Delivery in the Emergency Department: Bringing the Intensive Care Unit to the Patient.
Boarding of critically ill patients in the Emergency Department (ED) has increased over the past 20 years, leading hospital systems to explore ED-focused models of critical care delivery. ED-critical care delivery models vary between health systems due to differences in hospital resources and the needs of the critically ill patients boarding in the ED. Three published systems include an ED critical care intensivist consultation model, a hybrid model, and an ED-intensive care unit model. Paraphrasing the Greek philosopher, Plato, "necessity is the mother of invention." This proverb rings true as EDs are facing an increasing challenge of caring for boarding patients, especially those who are critically ill.

ReviewThe Role of Intermediate Care in Supporting Critically Ill Patients and Critical Care Infrastructure.
Intermediate care (IC) is used for patients who do not require the human and technological support of the intensive care unit (ICU) yet require more care and monitoring than can be provided on general wards. Though prevalent in many countries, there is marked variability in models of organization and staffing, as well as monitoring and interventions provided. In this article, the authors will discuss the historical background of IC, review the impact of IC on ICU and IC patient outcomes, and highlight where future studies can shed light on how to optimize IC organization and outcomes.

ReviewEarly Warning Systems for Critical Illness Outside the Intensive Care Unit.
Early warning systems (EWSs) are designed and deployed to create a rapid assessment and response for patients with clinical deterioration outside the intensive care unit (ICU). These models incorporate patient-level data such as vital signs and laboratory values to detect or prevent adverse clinical events, such as vital signs and laboratories to allow detection and prevention of adverse clinical events such as cardiac arrest, intensive care transfer, or sepsis. The applicability, development, clinical utility, and general perception of EWS in clinical practice vary widely. Here, we review the field as it has grown from early vital sign-based scoring systems to contemporary multidimensional algorithms and predictive technologies for clinical decompensation outside the ICU.

Aeromedical transport (AMT) is an integral part of healthcare systems worldwide. In this article, the personnel and equipment required, associated safety considerations, and evidence supporting the use of AMT is reviewed, with an emphasis on helicopter emergency medical services (HEMS). Indications for HEMS as guideded by the Air Medical Prehospital Triage Score are presented. Lastly, physiologic considerations, which are important to both AMT crews and receiving clinicians, are reviewed.

ReviewCritical Illness Outside the Intensive Care Unit: Research Challenges in Emergency and Prehospital Settings.
Patients with acute critical illness require prompt interventions, yet high-quality evidence supporting many investigations and treatments is lacking. Clinical research in this setting is challenging due to the need for immediate treatment and the inability of patients to provide informed consent. Attempts to obtain consent from surrogate decision-makers can be intrusive and lead to unacceptable delays to treatment. These problems may be overcome by pragmatic approaches to study design and the use of supervised waivers of consent, which is ethical and appropriate in situations where there is high risk of poor outcome and a paucity of proven effective treatment.
