The objective was to determine the nasal carriage prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among emergency medical service (EMS) personnel and the associated risk factors. A cross-sectional study was conducted among Ohio EMS personnel randomly sampled from 84 urban and rural agencies. Surveys assessing demographics, occupational history, health, cohabitation status, and hygiene practice were collected with nasal swabs from those who enrolled. ⋯ The high prevalence of MRSA in Ohio EMS personnel is both an occupational hazard and patient safety concern. Implementing methods to reinforce CDC guidelines for proper hygiene could decrease MRSA found in the EMS setting. Previous literature suggests that a reduction in MRSA colonization can lead to decreases in transmission and improved health for both patients and personnel.

Observational Study
Utilizing Geographic Information Systems to Identify Clusters of Severe Sepsis Patients Presenting in the Out-of-Hospital Environment.
Understanding the geographic distribution of critical illness within a community may provide public health stakeholders with information that can be used to expedite access to specialized care. We hypothesized that severe sepsis patients transported by emergency medical services (EMS) exhibit geospatial clustering and that prehospital providers would recognize sepsis more frequently in patients transported from sepsis clusters. Retrospective review of a prospective, observational study of patients with severe sepsis transported to the emergency department (ED) by EMS and treated with early goal-directed therapy (EGDT). ⋯ age <18 or need for immediate surgery. Patient location at the time of EMS activation was recorded. Analysis of the addresses identified clusters, defined as a location in which EMS transported more than one patient experiencing the above associated signs and symptoms of septic shock. Other data collected included self-reported patient location as private residence or chronic care facility. One hundred sixty severe sepsis patients transported by EMS were eligible for analysis, presenting from 125 locations. Ninety-one patients (57%) presented from a private residence and 69 (37%) from a chronic care facility. Fifty (31%) patients were transported from 15 locations, with 25 of those transported from just 4 locations. Cluster patients tended to be older, come from medical facilities, and were more likely to have sepsis recognized by prehospital providers. Results from this study demonstrate low pre-hospital recognition of sepsis, as well as geospatially clustered presentations, most notably from skilled nursing facilities. Community education, public health initiatives, and EMS interventions could be targeted in such clusters of cases in order to both improve sepsis recognition and potentially expedite time-sensitive interventions.

Prehospital dosing errors affect approximately 56,000 US children yearly. To decrease these errors, barriers, enablers and solutions from the paramedic (EMT-P) and medical director (MD) standpoint need to be understood. We conducted a mixed-methods study of EMT-P and MDs in Michigan utilizing focus groups (FG). ⋯ Simplification of dose delivery, an improved length based tape for EMS, pediatric checklists, and dose cards in mL were given as solutions. This mixed-methods study identified barriers and potential solutions to reducing prehospital pediatric drug dosing errors. Solutions should be thoroughly tested prior to implementation.

The 2013 ACCF/AHA guideline for the management of ST elevation myocardial infarction (STEMI) recommends that patients be transported by emergency medical services (EMS) directly to a percutaneous coronary intervention (PCI)-capable hospital. We examined the effects of EMS use according to inter-hospital transfer on time to PCI in STEMI patients. ⋯ EMS use significantly increased the odds of timely primary PCI to patients directly transported to a primary PCI center, but not in patients transferred from another hospital. EMS systems that identify STEMI patients and transport them to PCI capable hospitals, and processes to expedite the transfer of patients between non-PCI and PCI hospitals need to be developed further.

Case Reports
A Novel Approach to Improve Time to First Shock in Prehospital STEMI Complicated by Ventricular Fibrillation.
Lethal cardiac arrhythmias such as ventricular fibrillation and pulseless ventricular tachycardia (VF/pVT) complicate up to 6% of all out-of-hospital STEMIs. Typically, paramedics respond to this by applying defibrillation pads and delivering a shock as soon as possible. A recently introduced "pads-on" protocol directed paramedics to apply defibrillation pads to all STEMI patients (regardless of clinical stability) with the aim of decreasing time to first shock. ⋯ An important difference in the time to first shock is noted between the two patients with STEMI complicated by VF. While it took 2 min 43 s for the pads-off patient to be defibrillated, only 27 s elapsed before the pads-on patient was defibrillated. These two cases demonstrate that the application of defibrillation pads immediately following the diagnosis of prehospital STEMI has the potential to decrease the time to shock in patients suffering VF/pVT.
