Rising demand for emergency and urgent care services is well documented, as are the consequences, for example, emergency department (ED) crowding, increased costs, pressure on services, and waiting times. Multiple factors have been suggested to explain why demand is increasing, including an aging population, rising number of people with multiple chronic conditions, and behavioral changes relating to how people choose to access health services. The aim of this systematic mapping review was to bring together published research from urgent and emergency care settings to identify drivers that underpin patient decisions to access urgent and emergency care. ⋯ We identified six distinct reasons explaining why patients choose to access emergency and urgent care services: limited access to or confidence in primary care; patient perceived urgency; convenience; views of family, friends, or other health professionals; and a belief that their condition required the resources and facilities offered by a particular healthcare provider. There is a need to examine demand from a whole system perspective to gain better understanding of demand for different parts of the emergency and urgent care system and the characteristics of patients within each sector.

Observational Study
The Association of Health Literacy with Preventable ED Visits: A Cross-Sectional Study.
Policymakers argue that emergency department (ED) visits for conditions preventable with high-quality outpatient care contribute to waste in the healthcare system. However, access to ambulatory care is uneven, especially for vulnerable populations like minorities, the poor, and those with limited health literacy. The impact of limited health literacy on ED visits that are preventable with timely, high-quality ambulatory care is unknown. ⋯ Our results suggest that the ED may be an important site to deploy universal literacy-sensitive precautions and to test literacy-sensitive interventions with the goal of reducing the burden of potentially preventable ED visits on patients and the healthcare system.

Out-of-hospital advanced cardiac life support (ACLS) has not consistently shown a positive impact on survival. Extracorporeal cardiopulmonary resuscitation (E-CPR) could render prolonged on-site resuscitation (ACLS or basic cardiac life support [BCLS]) undesirable in selected cases. The objectives of this study were to evaluate, in patients suffering from out-of-hospital cardiac arrest (OHCA) and in a subgroup of potential E-CPR candidates, the association between the addition of prehospital ACLS to BCLS and survival to hospital discharge, prehospital return of spontaneous circulation (ROSC), and delay from call to hospital arrival. ⋯ In a tiered-response urban emergency medical service setting, prehospital ACLS is not associated with an improvement in survival to hospital discharge in patients suffering from OHCA and in potential E-CPR candidates, but with an improvement in prehospital ROSC and with longer delay to hospital arrival.

Comparative Study
Efficacy of intravenous cobinamide versus hydroxocobalamin or saline for treatment of severe hydrogen sulfide toxicity in a swine (Sus Scrofa) model.
Hydrogen sulfide (H2 S) is a potentially deadly gas that naturally occurs in petroleum and natural gas. The Occupational Health and Safety Administration cites H2 S as a leading cause of workplace gas inhalation deaths. Mass casualties of H2 S toxicity may be caused by exposure from industrial accidents or release from oil field sites. H2 S is also an attractive terrorism tool because of its high toxicity and ease with which it can be produced. Several potential antidotes have been proposed for hydrogen sulfide poisoning but none have been completely successful. ⋯ Cobinamide successfully rescued the severely NaHS-poisoned swine from apnea in the absence of assisted ventilation.
