Evaluating barriers to community CPR education.

OBJECTIVE: The primary objective of this study is to better understand the preferences of the general public regarding cardiopulmonary resuscitation (CPR) education as it relates to both format and the time and place of delivery. METHODS: Survey data were collected from a convenience sample at large public gatherings in Baltimore, Maryland, between May 23, 2015, and February 11, 2017. The survey was a 23-item single-page instrument administered at fairs and festivals. RESULTS: A total of 516 surveys were available for analysis. Twenty-four percent of the total population reported being very confident in performing CPR (scoring 8 to 10 on a Likert scale). Thirty-two percent of respondents who had previously taken a CPR class reported being very confident in performing CPR. A stepwise decline in reported confidence in performing CPR was observed as the time from last CPR class increased. Among all respondents the most favored instruction style was an instructor-led class. Least favorable was a local learning station at an event. The most favored location for instruction were libraries, while community festivals were least favored. CONCLUSION: Respondent preferences regarding the location and style of the training differed little between socioeconomic groups. Instructor-led instruction at local libraries was the most preferred option. CPR education offered at local learning stations during events and at community festivals were least favored among respondents. This study's findings can be used to more effectively structure CPR outreach and educational programs in an attempt to increase rates of bystander CPR.

Evaluating Barriers to Bystander CPR among Laypersons before and after Compression-only CPR Training.

OBJECTIVE: Bystander CPR is an essential part of out-of-hospital cardiac arrest (OHCA) survival. EMS and public safety jurisdictions have embraced initiatives to teach compression-only CPR to laypersons in order to increase rates of bystander CPR. We examined barriers to bystander CPR amongst laypersons participating in community compression-only CPR training and the ability of the training to alleviate these barriers. The barriers analyzed include fear of litigation, risk of disease transmission, fear of hurting someone as a result of doing CPR when unnecessary, and fear of hurting someone as a result of doing CPR incorrectly. METHODS: Laypersons attending community compression-only CPR training were administered surveys before and after community CPR training. Data were analyzed via standard statistical analyses. RESULTS: A total of 238 surveys were collected and analyzed between September 2015 and January 2016. The most common reported motivation for attending CPR training was "to be prepared/just in case" followed by "infant or child at home." Respondents reported that they were significantly more likely to perform CPR on a family member than a stranger in both pre-and post-training responses. Nevertheless, reported self-confidence in and likelihood of doing CPR on both family and strangers increased from pre-training to post-training. There was a statistically significant decrease in reported likelihood of all four barriers to prevent respondents from performing bystander CPR when pre-training responses were compared to post-training responses. Previous CPR training and history of having witnessed a sudden cardiac arrest (SCA) were both associated with decreased barriers to CPR, but previous training had no effect on reported likelihood of or confidence in performing CPR. CONCLUSION: The training initiative studied significantly reduced the reported likelihood of all barriers studied to prevent respondents from performing bystander CPR and also increased the reported confidence in doing CPR and likelihood of doing CPR on both strangers and family. However, it did not alleviate the pre-training discrepancy between likelihood of performing CPR on strangers versus family. Previous CPR training or certification had no impact on likelihood of or confidence in performing CPR.

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

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 jurisdiction's 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 $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.

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.

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

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.

Mass-Gathering Medical Care in Electronic Dance Music Festivals.

Introduction Electronic dance music (EDM) festivals represent a unique subset of mass-gathering events with limited guidance through literature or legislation to guide mass-gathering medical care at these events. Hypothesis/Problem Electronic dance music festivals pose unique challenges with increased patient encounters and heightened patient acuity under-estimated by current validated casualty predication models. METHODS: This was a retrospective review of three separate EDM festivals with analysis of patient encounters and patient transport rates. Data obtained were inserted into the predictive Arbon and Hartman models to determine estimated patient presentation rate and patient transport rates. RESULTS: The Arbon model under-predicted the number of patient encounters and the number of patient transports for all three festivals, while the Hartman model under-predicted the number of patient encounters at one festival and over-predicted the number of encounters at the other two festivals. The Hartman model over-predicted patient transport rates for two of the three festivals. CONCLUSION: Electronic dance music festivals often involve distinct challenges and current predictive models are inaccurate for planning these events. The formation of a cohesive incident action plan will assist in addressing these challenges and lead to the collection of more uniform data metrics.

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.

Mass-gathering medical care: a review of the literature.

UNLABELLED: Mass-gatherings events provide a difficult setting for which to plan an appropriate emergency medical response. Many of the variables that affect the level and types of medical needs, have not been fully researched. This review examines these variables. METHODS: An extensive review was conducted using the computerized databases Medline and Healthstar from 1977 through May 2002. Articles selected contained information pertaining to mass-gathering variables. These articles were read, abstracted, analyzed, and compiled. RESULTS: Multiple variables are present during a mass gathering, and they interact in complex and dynamic ways. The interaction of these variables contributes to the number of patients treated at an event (medical usage rate) as well as the observed injury patterns. Important variables include weather, event type, event duration, age, crowd mood and density, attendance, and alcohol and drug use. CONCLUSIONS: Developing an understanding of the variables associated with mass gatherings should be the first step for event planners. After these variables are considered, a thorough needs analysis can be performed and resource allocation can be based on objective data.

Variables influencing medical usage rates, injury patterns, and levels of care for mass gatherings.

OBJECTIVES: Mass gatherings create difficult environments for which to plan emergency medical responses. The purpose of this study was to identify those variables that are associated with increased medical usage rates (MURs) and certain injury patterns that can be used to facilitate the planning process. METHODS: Patient information collected at three types of mass gatherings (professional American football and baseball games and rock concerts) over a three-year period was reviewed retrospectively. Specific variables were abstracted: (1) event type; (2) gender; (3) age; (4) weather; and (5) attendance. All 216 events (total attendance 9,708,567) studied were held in the same metropolitan region. All MURs are reported as patients per 10,000 (PPTT). RESULTS: The 5,899 patient encounters yielded a MUR of 6.1 PPTT. Patient encounters totaled 3,659 for baseball games (4.85 PPTT), 1,204 for football games (6.75 PPTT), and 1,036 for rock concerts (30 PPTT). The MUR for Location A concerts (no mosh pits) was 7.49 PPTT, whereas the MUR for the one Location B concert (with mosh pits) was 110 PPTT. The MUR for Location A concerts was higher than for baseball, but not football games (p = 0.005). Gender distribution was equal among patrons seeking medical care. The mean values for patient ages were 29 years at baseball games, 33 years at football games, and 20 years at concerts. The MUR at events held when the apparent temperature was 80 degrees F significantly lower statistically than that at events conducted at temperatures <80 degrees F were (18 degrees C) (4.90 vs. 8.10 PPTT (p = 0.005)). The occurrence of precipitation and increased attendance did not predict an increased MUR. Medical care was sought mostly for minor/basic-level care (84%) and less so for advanced-level care (16%). Medical cases occurred more often at sporting events (69%), and were more common than were cases with traumatic injuries (31%). Concerts with precipitation and rock concerts had a positive association with the incidence of trauma and the incidence of injuries; whereas age and gender were not associated with medical or traumatic diagnoses. CONCLUSIONS: Event type and apparent temperature were the variables that best predicted MUR as well as specific injury patterns and levels of care.

Assessing pediatric and young adult substance use through analysis of prehospital data.

INTRODUCTION: Substance use in young adults is a significant and growing problem. Emergency Medical Services (EMS) personnel often encounter this problem, yet the use of prehospital data to evaluate the prevalence and magnitude of substance abuse has been limited. HYPOTHESIS/PROBLEM: This study evaluated drug and alcohol use through the use of prehospital and EMS data in one suburban county in Maryland (USA). The primary hypothesis was that the type of drug being abused is associated with age. The secondary hypothesis was substance abuse incidence is associated with location. The tertiary hypothesis was that substance abuse is associated with a history of mental illness. METHODS: Deidentified patient care reports (PCRs) were obtained during a 24-month period from October 2010 through September 2012 for patients 0 through 25 years of age. Inclusion criteria included chief complaint of alcohol overdose, drug overdose, or the use of naloxone. RESULTS: The primary hypothesis was supported that age was associated with drug category (P < .001). Younger adolescents were more likely to use household items, prescription drugs, or over-the-counter drugs, whereas older adolescents were more likely to use illicit drugs. The secondary hypothesis was supported that both alcohol (P < .001) and drugs (P < .001) were associated with location of call. Calls involving alcohol were more likely to be at a home or business, whereas calls involving drugs were more likely to be at home or at a public venue. The tertiary hypothesis was supported that both alcohol (P = .001) and drug use (P < .001) were associated with history of mental illness. Older adolescents were more likely to report a history of mental illness. Chi-squared tests indicated there were significant differences between genders and drug category (P = .002) and gender and current suicide attempt (P = .004). Females were more likely to use prescription drugs, whereas males were more likely to use illicit drugs. Calls involving younger adolescents under 18 were more likely to be at school or the mall, whereas calls involving older adolescents were likely to be at a prison, public venue, or a business. CONCLUSION: All three hypotheses were supported: the type of substance being abused was associated with both age and location, and substance abuse was associated with a history of mental illness. This research has important implications for understanding how EMS resources are utilized for substance use. This information is valuable in not only the education and training of prehospital care providers, but also for the targeting of future public health interventions.
