Patients without ST elevation after return of spontaneous circulation may benefit from emergent percutaneous intervention: A systematic review and meta-analysis

INTRODUCTION The American Heart Association recommends that post-arrest patients with evidence of ST elevation myocardial infarction (STEMI) on electrocardiogram (ECG) be emergently taken to the catheterization lab for percutaneous coronary intervention (PCI). However, recommendations regarding the utility of emergent PCI for patients without ST elevation are less specific. This review examined the literature on the utility of PCI in post-arrest patients without ST elevation compared to patients with STEMI. METHODS A systematic review of the English language literature was performed for all years to March 1, 2015 to examine the hypothesis that a percentage of post-cardiac arrest patients without ST elevation will benefit from emergent PCI as defined by evidence of an acute culprit coronary lesion. RESULTS Out of 1067 articles reviewed, 11 articles were identified that allowed for analysis of data to examine our study hypothesis. These studies show that patients presenting post cardiac arrest with STEMI are thirteen times more likely to be emergently taken to the catheterization lab than patients without STEMI; OR 13.8 (95% CI 4.9-39.0). Most importantly, the cumulative data show that when taken to the catheterization lab as much as 32.2% of patients without ST elevation had an acute culprit lesion requiring intervention, compared to 71.9% of patients with STEMI; OR 0.15 (95% CI 0.06-0.34). CONCLUSION The results of this systematic review demonstrate that nearly one third of patients who have been successfully resuscitated from cardiopulmonary arrest without ST elevation on ECG have an acute lesion that would benefit from emergent percutaneous coronary intervention.

A poor association between out-of-hospital cardiac arrest location and public automated external defibrillator placement.

INTRODUCTION Much attention has been given to the strategic placement of automated external defibrillators (AEDs). The purpose of this study was to examine the correlation of strategically placed AEDs and the actual location of cardiac arrests. METHODS A retrospective review of data maintained by the Maryland Institute for Emergency Medical Services Systems (MIEMSS), specifically, the Maryland Cardiac Arrest Database and the Maryland AED Registry, was conducted. Location types for AEDs were compared with the locations of out-of-hospital cardiac arrests in Howard County, Maryland. The respective locations were compared using scatter diagrams and r2 statistics. RESULTS The r2 statistics for AED location compared with witnessed cardiac arrest and total cardiac arrests were 0.054 and 0.051 respectively, indicating a weak relationship between the two variables in each case. No AEDs were registered in the three most frequently occurring locations for cardiac arrests (private homes, skilled nursing facilities, assisted living facilities) and no cardiac arrests occurred at the locations where AEDs were most commonly placed (community pools, nongovernment public buildings, schools/educational facilities). CONCLUSION A poor association exists between the location of cardiac arrests and the location of AEDs.

The Price of a Helping Hand: Modeling the Outcomes and Costs of Bystander CPR

Abstract Objective. Early, high-quality, minimally interrupted bystander cardio-pulmonary resuscitation (BCPR) is essential for out-of-hospital cardiac arrest survival. However, rates of bystander intervention remain low in many geographic areas. Community CPR programs have been initiated to combat these low numbers by teaching compression-only CPR to laypersons. This study examined bystander CPR and the cost-effectiveness of a countywide CPR program to improve out-of-hospital cardiac arrest survival. Methods. A 2-year retrospective review of emergency medical services (EMS) run reports for adult nontraumatic cardiac arrests was performed using existing prehospital EMS quality assurance data. The incidence and success of bystander CPR to produce prehospital return of spontaneous circulation and favorable neurologic outcomes at hospital discharge were analyzed. The outcomes were paired with cost data for the jurisdictions community CPR program to develop a cost-effectiveness model. Results. During the 23-month study period, a total of 371 nontraumatic adult out-of-hospital cardiac arrests occurred, with a 33.4% incidence of bystander CPR. Incremental cost-effectiveness analysis for the community CPR program demonstrated a total cost of

Assessing attitudes toward spinal immobilization.

22,539 per quality-adjusted life-year (QALY). A significantly increased proportion of those who received BCPR also had an automated external defibrillator (AED) applied. There was no correlation between witnessed arrest and performance of BCPR. A significantly increased proportion of those who received BCPR were found to be in a shockable rhythm when the initial ECG was performed. In the home setting, the chances of receiving BCPR were significantly smaller, whereas in the public setting a nearly equal number of people received and did not receive BCPR. Witnessed arrest, AED application, public location, and shockable rhythm on initial ECG were all significantly associated with positive ROSC and neurologic outcomes. A home arrest was significantly associated with worse neurologic outcome. Conclusions. Cost-effectiveness analysis demonstrates that a community CPR outreach program is a cost-effective means for saving lives when compared to other healthcare-related interventions. Bystander CPR showed a clear trend toward improving the neurologic outcome of survivors. The findings of this study indicate a need for additional research into the economic effects of bystander CPR.

Variables associated with effects on morbidity in older adults following disasters

BACKGROUND Prospective studies have improved knowledge of prehospital spinal immobilization. The opinion of Emergency Medical Services (EMS) providers regarding spinal immobilization is unknown, as is their knowledge of recent research advances. STUDY OBJECTIVES To examine the attitudes, knowledge, and comfort of prehospital and Emergency Department (ED) EMS providers regarding spinal immobilization performed under a non-selective protocol. METHODS An online survey was conducted from May to July of 2011. Participants were drawn from the Howard County Department of Fire and Rescue Services and the Howard County General Hospital ED. The survey included multiple choice questions and responses on a modified Likert scale. Correlation analysis and descriptive data were used to analyze results. RESULTS Comfort using the Kendrick Extrication Device was low among ED providers. Experienced providers were more likely to indicate comfort using this device. Respondents often believed that spinal immobilization is appropriate in the management of penetrating trauma to the chest and abdomen. Reported use of padding decreased along with the frequency with which providers practice and encounter immobilized patients. Respondents often indicated that they perform spinal immobilization due solely to mechanism of injury. Providers who feel as if spinal immobilization is often performed unnecessarily were more likely to agree that immobilization causes an unnecessary delay in patient care. CONCLUSIONS The results demonstrate the need for improved EMS education in the use of the Kendrick Extrication Device, backboard padding, and spinal immobilization in the management of penetrating trauma. The attitudes highlighted in this study are relevant to the implementation of a selective spinal immobilization protocol.

Stop the Bleed Education Consortium: Education program content and delivery recommendations

Introduction: Older adults are vulnerable to disproportionately higher morbidity following disasters. Reasons for this vulnerability are multifaceted and vary by disaster type as well as patient comorbidities. Efforts to mitigate this increased morbidity require identification of at-risk older adults who can be targeted for intervention. Methods: A PubMed search was performed using the search terms “geriatric, disaster” and “morbidity, disaster” to identify published articles that reported variables associated with increased morbidity of older adults during and after disasters. A review of article titles and abstracts was then conducted to identify those articles that contained evidence-based variables that render older adults vulnerable to poor health outcomes during disasters. Results: A total of 233 studies was initially identified. After applying exclusion criteria, nine studies were chosen for the comprehensive review. Based on the synthesis of the literature, factors were identified that were repeatedly associated with morbidity and mortality among older adults during and shortly after disasters. Conclusion: Older adults, especially those with multiple co-morbidities, are at risk of increased morbidity after disasters and catastrophic events. Factors such as the need for prescription medications, low social support, visual and hearing impairment, impaired mobility, and poor economic status are associated with an increased risk of morbidity.

A human factors analysis of an EMS Crew's exposure to carbon monoxide

Following the 2015 White House launch of the Stop the Bleed (STB) campaign various educational programs have emerged to teach hemorrhage control principles to the public. The STB campaign seeks to translate battlefield medicine successes to the civilian sector by empowering the general public to sto

Public Access Bleeding Control: Enhancing Local Resilience.

The safety of personnel and resources is considered to be a cornerstone of prehospital Emergency Medical Services (EMS) operations and practice. However, barriers exist that limit the comprehensive reporting of EMS safety data. To overcome these barriers, many high risk industries utilize a technique called Human Factors Analysis (HFA) as a means of error reduction. The goal of this approach is to analyze processes for the purposes of making an environment safer for patients and providers. This report describes an application of this approach to safety incident analysis following a situation during which a paramedic ambulance crew was exposed to high levels of carbon monoxide.

The Columbia Mall shooting: reflections of a physician responder.

INTRODUCTION Prehospital Emergency Medical Services (EMS) providers are expected to treat all patients the same, regardless of race, gender identity, sexual orientation, or religion. Some EMS personnel who are poorly trained in working with lesbian, gay, bisexual, and transgender (LGBT) patients are at risk for managing such patients incompletely and possibly incorrectly. During emergency situations, such mistreatment has meant the difference between life and death. METHODS An anonymous survey was electronically distributed to EMS educational program directors in Maryland (USA). The survey asked participants if their program included training cultural sensitivity, and if so, by what modalities. Specific questions then focused on information about LGBT education, as well as related topics, that they, as program directors, would want included in an online training module. RESULTS A total of 20 programs met inclusion criteria for the study, and 16 (80%) of these programs completed the survey. All but one program (15, 94%) included cultural sensitivity training. One-third (6, 38%) of the programs reported already teaching LGBT-related issues specifically. Three-quarters of the programs that responded (12, 75%) were willing to include LGBT-related material into their curriculum. All programs (16, 100%) identified specific aspects of LGBT-related emergency health issues they would be interested in having included in an educational module. CONCLUSION Most EMS educational program directors in Maryland are receptive to including LGBT-specific education into their curricula. The information gathered in this survey may help guide the development of a short, self-contained, open-access module for EMS educational programs. Further research, on a broader scale and with greater geographic sampling, is needed to assess the practices of EMS educators on a national level.
