Mass gatherings are heterogeneous in terms of size, duration, type of event, crowd behavior, demographics of the participants and spectators, use of recreational substances, weather, and environment. The goals of health and medical services should be the provision of care for participants and spectators consistent with local standards of care, protection of continuing medical service to the populations surrounding the event venue, and preparation for surge to respond to extraordinary events. Pre-event planning among jurisdictional public health and EMS, acute care hospitals, and event EMS is essential, but should also include, at a minimum, event security services, public relations, facility maintenance, communications technicians, and the event planners and organizers. ⋯ Research is needed to evaluate the skills and interventions required by EMS providers to achieve desired outcomes. The event-dedicated EMS Medical Director is integral to acceptable quality medical care provided at mass gatherings; hence, he/she must be included in all aspects of mass gathering medical care planning, preparations, response, and recovery. Incorporation of jurisdictional EMS and community hospital medical leadership, and emergency practitioners into these processes will ensure that on-site care, transport, and transition to acute care at appropriate receiving facilities is consistent with, and fully integrated into the community's medical care system, while fulfilling the needs of event participants.

Comparative Study Observational Study
A Comparison of Invasive Airway Management and Rates of Pneumonia in Prehospital and Hospital Settings.
Infection is a major cause of morbidity and mortality in trauma. Infection in trauma is poorly understood. The impact of prehospital invasive airway management (IAM) on the incidence of pneumonia and health services utilization is unknown. We hypothesized that trauma patients exposed to prehospital IAM will suffer higher rates of pneumonia compared to no IAM or exposure to IAM performed in the hospital. We hypothesized that patients who develop pneumonia subsequent to prehospital IAM will have longer intensive care unit (ICU) and hospital length of stay (LOS) compared to patients who acquired pneumonia after IAM performed in the hospital. ⋯ Exposure to IAM in prehospital and hospital settings results in an increase in pneumonia, but there does not appear to be a link between the source of pneumonia and an increase in ICU or hospital LOS.

Case Reports Randomized Controlled Trial Comparative Study
Prehospital Identification of Underlying Coronary Artery Disease by Community Paramedics.
There is a lack of definitive evidence that preventative, in-home medical care provided by highly trained community paramedics reduces acute health care utilization and improves the overall well-being of patients suffering from chronic diseases. The Expanding Paramedicine in the Community (EPIC) trial is a randomized controlled trial designed to investigate the use of community paramedics in chronic disease management (ClinicalTrials.gov ID: NCT02034045). This case of a patient randomized to the intervention arm of the EPIC study demonstrates how the added layer of frequent patient contact by community paramedics and real-time electronic medical record (EMR) correspondence between the paramedics, physicians and other involved practitioners prevented possible life-threatening complications. The visiting community paramedic deduced the need for an electrocardiogram, which prompted the primary care physician to order a stress test revealing abnormalities and thus a coronary artery bypass graft was performed without emergency procedures, unnecessary financial expenditure or further health degradation such as a myocardial infarction.

Comparative Study Observational Study
EMS Intubation Improves with King Vision Video Laryngoscopy.
Intubation success by paramedics has historically been variable. The lack of first-pass success (FPS) has been associated with increased adverse events. Various video laryngoscope (VL) devices have been investigated to improve success among paramedics. Conflicting research exists on VL vs. direct laryngoscopy (DL) by paramedics and on the effects of the specific King Vision device on FPS and overall success (OS) in an emergency medical services (EMS) system with low intubation frequency and historically low success rates. ⋯ In this suburban EMS system with historically low intubation success rates and low frequency of intubation, paramedics were able to improve all measures of intubation success using the King Vision video laryngoscope and an ongoing training program when compared with direct laryngoscopy.

Comparative Study
Probability of Return of Spontaneous Circulation as a Function of Timing of Vasopressor Administration in Out-of-Hospital Cardiac Arrest.
Vasopressors (epinephrine and vasopressin) are associated with return of spontaneous circulation (ROSC). Recent retrospective studies reported a greater likelihood of ROSC when vasopressors were administered within the first 10 minutes of arrest. However, it is unlikely that the relationship between ROSC and the timing of vasopressor administration is a binary function (i.e., ≤10 vs. >10 minutes). More likely, this relationship is a function of time measured on a continuum, with diminishing effectiveness even within the first 10 minutes of arrest, and potentially, some lingering benefit beyond 10 minutes. However, this relationship remains undefined. ⋯ We found that time to vasopressor administration is significantly associated with ROSC, and the odds of ROSC declines by 4% for every 1-minute delay between call receipt and vasopressor administration. These results support the notion of a time-dependent function of vasopressor effectiveness across the entire range of administration delays rather than just the first 10 minutes. Large, prospective studies are needed to determine the relationship between the timing of vasopressor administration and long-term outcomes.
