Prehospital high-dose sublingual nitroglycerin rarely causes hypotension.
High-dose intravenous nitroglycerin is a common in-hospital treatment for respiratory distress due to congestive heart failure (CHF) with hypertension. Intravenous (IV) nitroglycerin administration is impractical in the prehospital setting. In 2011, a new regional Emergency Medical Services (EMS) protocol was introduced allowing advanced providers to treat CHF with high-dose oral nitroglycerin. The protocol calls for patients to be treated with two sublingual tabs (0.8 mg) when systolic blood pressure (SBP) was >160 mm Hg, or three sublingual tabs (1.2 mg) when SBP was >200 mm Hg, every five minutes as needed. Hypothesis/Problem To assess the protocol's safety, the incidence of hypotension following prehospital administration of multiple simultaneous nitroglycerin (MSN) tabs by EMS providers was studied. ⋯ Hypotension was rare and self-limited in prehospital patients receiving MSN.

Video self-instruction for police officers in cardiopulmonary resuscitation and automated external defibrillators.
Police officers often serve as first responders during out-of-hospital cardiac arrests (OHCA). Current knowledge and attitudes about resuscitation techniques among police officers are unknown. Hypothesis/problem This study evaluated knowledge and attitudes about cardiopulmonary resuscitation (CPR) and automated external defibrillators (AEDs) among urban police officers and quantified the effect of video self-instruction (VSI) on these outcomes. ⋯ Video self-instruction can significantly improve attitudes toward and knowledge of CPR and AEDs among police officers. Future studies can assess the impact of VSI on actual rates of CPR and AED use during real out-of-hospital cardiac arrests.

Secure scalable disaster electronic medical record and tracking system.
Electronic medical records (EMRs) are considered superior in documentation of care for medical practice. Current disaster medical response involves paper tracking systems and radio communication for mass-casualty incidents (MCIs). These systems are prone to errors, may be compromised by local conditions, and are labor intensive. Communication infrastructure may be impacted, overwhelmed by call volume, or destroyed by the disaster, making self-contained and secure EMR response a critical capability. Report As the prehospital disaster EMR allows for more robust content including protected health information (PHI), security measures must be instituted to safeguard these data. The Wireless Internet Information System for medicAl Response in Disasters (WIISARD) Research Group developed a handheld, linked, wireless EMR system utilizing current technology platforms. Smart phones connected to radio frequency identification (RFID) readers may be utilized to efficiently track casualties resulting from the incident. Medical information may be transmitted on an encrypted network to fellow prehospital team members, medical dispatch, and receiving medical centers. This system has been field tested in a number of exercises with excellent results, and future iterations will incorporate robust security measures. ⋯ A secure prehospital triage EMR improves documentation quality during disaster drills.

Emergency nursing staff dispatch: sensitivity and specificity in detecting prehospital need for physician interventions during ambulance transport in Rovigo Emergency Ambulance Service, Italy.
In Italy, administration of medications or advanced procedures dictates the prehospital presence of a physician to initiate treatment. Nursing staff is often used as dispatchers in Italian emergency medical ambulance services. There is little data about nursing dispatch performance in detecting high-acuity patients who need prehospital medications and procedures. ⋯ A dispatch center staffed by nurses with six years of experience and three months of training correctly identified when not to send a doctor to the scene in the absence of need for physician interventions, using a subjective decision-making process. The nurses staffing the dispatch center also worked in the field. Dispatch center staff were not able to predict when there was no need for physician interventions in high-acuity dispatch code patients, resulting in an over-triage and use of emergency physicians on scene.

Suffolk Show 2011: prehospital medical coverage in a mass-gathering event.
Despite their popularity and unique characteristics, county shows, also known as agricultural fairs, are amongst the least-studied mass-gathering events. Suffolk Show is one of the biggest such events in the UK, attracting tens of thousands of people annually over a 2-day period. In addition to trade stands and livestock displays, the 2011 show included top international show jumping and other sport activities. Problem Due to the range of activities and large number of attendees of different ages and medical backgrounds, combined with a lack of objective data about medical contacts made during these events, medical officers and local emergency services find planning an appropriate level of medical coverage for county shows particularly challenging. This study involved analyzing the characteristics of medical contacts during a major county show and assessing the level of medical coverage provided. ⋯ The majority of presentations were due to minor injuries or ailments. An understanding of the event characteristics, demographics, and nature of medical contacts will provide organizers, medical officers, and local emergency services with information about the level of coverage and resources required. This data can further help advance knowledge of mass-gathering medicine across the various types of events.
