ABSTRACT
BACKGROUND: Pediatric patients with cancer commonly seek emergency department (ED) care, yet there is limited evidence on ED utilization patterns and disposition outcomes among these patients. METHODS: Retrospective analysis of the Healthcare Cost and Utilization Project State Emergency Department Databases and State Inpatient Databases for Maryland and New York from 2013 to 2017. We compared ED visits and disposition outcomes for 5.8 million pediatric patients (<18 years old) with and without cancer, and used multivariable regressions to estimate associations between the number of ED visits, hospital (inpatient) admissions through the ED, and ED or inpatient mortality and sociodemographic and clinical factors within the cancer cohort. RESULTS: Pediatric patients with cancer had more ED visits per year on average (2.4 vs. 1.5, p < .001), higher shares of admissions (56.8% vs. 6.6%, p < .001) and mortality (1.2% vs. 0.1%, p < .001) compared to those without cancer. Among patients with cancer, uninsured pediatric patients had fewer ED visits and lower risk of admission to a hospital through the ED compared to those with Medicaid coverage (total visits: incidence rate ratio [IRR]: 0.82, 95% confidence intervals [CI]: 0.75-0.90; admission: IRR: 0.75, 95% CI: 0.65-0.86). Mortality risks were higher for pediatric patients with cancer residing in areas with the lowest median household income, and with no health insurance coverage (IRR: 2.81, 95% CI: 1.21-6.51) compared to Medicaid. CONCLUSIONS: Our findings emphasize the importance of enhancing health insurance coverage policies and social services for pediatric patients with cancer and their families to address clinical and nonclinical needs.

BACKGROUND: Although frequent emergency department (ED) users have been widely studied in cross-sectional settings, there is some evidence suggesting that most frequent ED users do not remain frequent users over multiple consecutive years. The objective of this study was to explore the association between persistent multiyear frequent ED use and individuals' characteristics. METHODS: A retrospective analysis using the Healthcare Cost and Utilization Project State Emergency Department Databases (2012-2017) for individuals aged 18-59 who visited any ED in Florida, Massachusetts and New York was conducted. Multivariable regression models were used to estimate the association between persistent frequent ED use over time (≥4 ED visits in each data year) and individuals' characteristics and clinical factors compared with non-persistent frequent users (≥4 ED visits only in the baseline year). RESULTS: The databases for the three states included 3.3 million patients, who accounted for 4.5 million ED visits in the baseline year (2012). Of those, 3.2% of patients were frequent ED users (≥4 visits) accounting for 13.2% of all ED visits in the baseline year. Longitudinal follow-up revealed that 14.9% (15 617) of frequent users in 2012 remained persistently frequent ED users for 2-3 consecutive years and 3.6% (3774) for 4-6 consecutive years. Persistent frequent ED users differed significantly from non-persistent frequent ED users; they had more ED visits in the index year, were more likely to have no health insurance or public health insurance coverage, and had a higher prevalence of chronic conditions and comorbidities, and more ED visits for less medically urgent conditions. CONCLUSION: Differences exist between persistent and non-persistent frequent ED users that should be considered when implementing interventions designed to improve health outcomes and curtail healthcare expenditures generated by the broad population of frequent ED users.

INTRODUCTION: The Centres for Disease Control and Prevention (CDC) mandates that healthcare employees at high-risk exposure to Tuberculosis (TB) undergo annual testing. Currently, two methods of TB testing are used: a two-step skin test (TST) or a whole-blood test (IGRA). Healthcare leadership's test selection must account for not only direct costs such as procedure and resources but also indirect costs, including employee workplace absence. METHODS: A mathematical model based on Upstate South Carolina's largest health system affecting over 18,000 employees on six campuses was developed to investigate the value loss perspective of these testing methods and assist in decision-making. A process flow map identified the varied direct and indirect costs for each test for four employee types, and 6 travel-to-testing-site times were calculated. RESULTS: The switching point between testing procedures that minimised total system costs was most influenced by employee salary compared to travel distance. Switching from the current hospital policy to an integrated TST/IGRA testing could reduce TB compliance costs by 28%. CONCLUSIONS: This study recommends an integrated approach as cost-effective for large health systems with multiple campuses while considering the direct and indirect costs. When accounting for 'inconvenience costs' (stress, etc.) associated with visits, IGRAs are recommended irrespective of employee salary.

BACKGROUND: The frequency of head computed tomography (CT) imaging for mild head trauma patients has raised safety and cost concerns. Validated clinical decision rules exist in the published literature and on-line sources to guide medical image ordering but are often not used by emergency department (ED) clinicians. Using simulation, we explored whether the presentation of a clinical decision rule (i.e. Canadian CT Head Rule - CCHR), findings from malpractice cases related to clinicians not ordering CT imaging in mild head trauma cases, and estimated patient out-of-pocket cost might influence clinician brain CT ordering. Understanding what type and how information may influence clinical decision making in the ordering advanced medical imaging is important in shaping the optimal design and implementation of related clinical decision support systems. METHODS: Multi-center, double-blinded simulation-based randomized controlled trial. Following standardized clinical vignette presentation, clinicians made an initial imaging decision for the patient. This was followed by additional information on decision support rules, malpractice outcome review, and patient cost; each with opportunity to modify their initial order. The malpractice and cost information differed by assigned group to test the any temporal relationship. The simulation closed with a second vignette and an imaging decision. RESULTS: One hundred sixteen of the 167 participants (66.9%) initially ordered a brain CT scan. After CCHR presentation, the number of clinicians ordering a CT dropped to 76 (45.8%), representing a 21.1% reduction in CT ordering (P = 0.002). This reduction in CT ordering was maintained, in comparison to initial imaging orders, when presented with malpractice review information (p = 0.002) and patient cost information (p = 0.002). About 57% of clinicians changed their order during study, while 43% never modified their imaging order. CONCLUSION: This study suggests that ED clinician brain CT imaging decisions may be influenced by clinical decision support rules, patient out-of-pocket cost information and findings from malpractice case review.

BACKGROUND: To improve patient outcomes, the Center for Medicare and Medicaid Services (CMS) implemented core measures that outline the initial treatment of the septic patient. These measures include initial blood culture collection prior to antibiotics, adequate intravenous fluid resuscitation, and early administration of broad spectrum antibiotics. We sought to determine if Paramedics can initiate the CMS sepsis core measure bundle in the prehospital field reliably. METHODS: This is a retrospective, case series from a 3rd service EMS system model in Greenville, South Carolina between November 17, 2014 and February 20, 2016. An adult Prehospital Sepsis Assessment Tool was created using the 2012 Surviving Sepsis guidelines: 2 of 3 signs of systemic inflammatory response (heart rate, respiratory rate, oral temperature) and a known or suspected source of infection. A "Sepsis Alert" was called by paramedics and upon IV access a set of blood cultures and blood for lactate analysis was collected prior to field antibiotic administration. The Sepsis Alert was compared to serum lactate levels and ICD 9 or 10 admitting diagnosis of Sepsis, Severe Sepsis, or Septic Shock. Blood culture contamination, serum lactate, and antibiotic match were determined by in-hospital laboratory analysis. RESULTS: A total of 120 trained paramedics called 1,185 "Sepsis Alerts" on 56,643 patients (50.3% Male, mean age 70). Patients with missing discharge diagnosis were eliminated (n = 31). The admitting diagnosis of sepsis overall was 73.5% (848/1154): Sepsis 50% (578/1154), Severe Sepsis 14.6% (169/1154), Septic Shock 8.9% (101/1154). A total of 946 blood cultures were collected in the prehospital setting, with a 95.04% (899/946) no contamination rate. Contamination was found in 4.96% (47/946). A total of 179 (18.9%) of the uncontaminated blood cultures were found to have positive growth with 720 (76.1%) having no growth. EMS administered antibiotics matched blood culture positive growth in 72% of patients. The lactate level was greater than 2.2 in 46.9% of patients. No adverse effects were reported after prehospital administration of antibiotics. CONCLUSION: This study demonstrates the successful implementation of an EMS-driven CMS Sepsis Core Measure bundle in the prehospital setting. Paramedics can acquire uncontaminated blood cultures, and safely administer antibiotics prior to hospital arrival among patients who were recognized as sepsis alerts.

BACKGROUND: An estimated 20% of patients arriving by ambulance to the emergency department are in moderate to severe pain. However, the management of pain in the prehospital setting has been shown to be inadequate. Untreated pain may have negative physiologic and psychological consequences. The prehospital community has acknowledged this inadequacy and made treatment of pain a priority. OBJECTIVES: To determine if system-wide pain management improvement efforts (i.e. education and protocol implementation) improve the assessment of pain and treatment with opioid medications in the prehospital setting and to determine if improvements are maintained over time. METHODS: This was a retrospective before and after study of a countywide prehospital patient care database. The study population included all adult patients transported by EMS between February 2004 and February 2012 with a working assessment of trauma or burn. EMS patient care records were searched for documentation of pain scores and opioid administration. Four time periods were examined: 1) before interventions, 2) after pediatric specific pain management education, 3) after pain management protocol implementation, and 4) maintenance phase. Frequencies and 95% confidence intervals were calculated for all patients meeting the inclusion criteria in each time period and Chi-square was used to compare frequencies between time periods. RESULTS: 15,228 adult patients transported by EMS during the study period met the inclusion criteria. Subject demographics were similar between the four time periods. Pain score documentation improved between the time periods but was not maintained over time (13% [95%CI 12-15%] to 32% [95%CI 31-34%] to 29% [95 CI 27-30%] to 19% [95%CI 18-21%]). Opioid administration also improved between the time periods and was maintained over time (7% [95%CI 6-8%] to 18% [95%CI 16-19%] to 24% [95%CI 22-25%] to 23% [95% CI 22-24%]). CONCLUSIONS: In adult patients both pediatric-focused education and pain protocol implementation improved the administration of opioid pain medications. Documentation and assessment of pain scores was less affected by specific pain management improvement efforts.

Abstract Early, high-quality cardiopulmonary resuscitation (CPR) is the key to increasing the likelihood of successful resuscitation in cardiac arrest. The use of dispatch-assisted (DA) CPR can increase the likelihood of bystander CPR. We describe a case in which a metronome was introduced to guide DA-CPR. The wife of a 52-year-old male activated 9-1-1 after her husband suffered a cardiac arrest. During her 9-1-1 call she received CPR instructions and heard a metronome over the phone while following the instructions. Return of spontaneous circulation of the patient occurred during paramedic on scene care. The patient was transported to hospital and discharged 6 days later with no neurological deficit. This case supports the use of a metronome by emergency medical dispatchers during the provision of DA-CPR to improve bystander CPR.
ABSTRACT
INTRODUCTION: Accuracy and effectiveness analyses of mass casualty triage systems are limited because there are no gold standard definitions for each of the triage categories. Until there is agreement on which patients should be identified by each triage category, it will be impossible to calculate sensitivity and specificity or to compare accuracy between triage systems. OBJECTIVE: To develop a consensus-based, functional gold standard definition for each mass casualty triage category. METHODS: National experts were recruited through the lead investigators' contacts and their suggested contacts. Key informant interviews were conducted to develop a list of potential criteria for defining each triage category. Panelists were interviewed in order of their availability until redundancy of themes was achieved. Panelists were blinded to each other's responses during the interviews. A modified Delphi survey was developed with the potential criteria identified during the interview and delivered to all recruited experts. In the early rounds, panelists could add, remove, or modify criteria. In the final rounds edits were made to the criteria until at least 80% agreement was achieved. RESULTS: Thirteen national and local experts were recruited to participate in the project. Six interviews were conducted. Three rounds of voting were performed, with 12 panelists participating in the first round, 12 in the second round, and 13 in the third round. After the first two rounds, the criteria were modified according to respondent suggestions. In the final round, over 90% agreement was achieved for all but one criterion. A single e-mail vote was conducted on edits to the final criterion and consensus was achieved. CONCLUSION: A consensus-based, functional gold standard definition for each mass casualty triage category was developed. These gold standard definitions can be used to evaluate the accuracy of mass casualty triage systems after an actual incident, during training, or for research.

BACKGROUND: In a departure from the previous strategy of immediate defibrillation, the 2005 resuscitation guidelines from the American Heart Association-International Liaison Committee on Resuscitation suggested that emergency medical service (EMS) personnel could provide 2 minutes of cardiopulmonary resuscitation (CPR) before the first analysis of cardiac rhythm. We compared the strategy of a brief period of CPR with early analysis of rhythm with the strategy of a longer period of CPR with delayed analysis of rhythm. METHODS: We conducted a cluster-randomized trial involving adults with out-of-hospital cardiac arrest at 10 Resuscitation Outcomes Consortium sites in the United States and Canada. Patients in the early-analysis group were assigned to receive 30 to 60 seconds of EMS-administered CPR and those in the later-analysis group were assigned to receive 180 seconds of CPR, before the initial electrocardiographic analysis. The primary outcome was survival to hospital discharge with satisfactory functional status (a modified Rankin scale score of ≤3, on a scale of 0 to 6, with higher scores indicating greater disability). RESULTS: We included 9933 patients, of whom 5290 were assigned to early analysis of cardiac rhythm and 4643 to later analysis. A total of 273 patients (5.9%) in the later-analysis group and 310 patients (5.9%) in the early-analysis group met the criteria for the primary outcome, with a cluster-adjusted difference of -0.2 percentage points (95% confidence interval, -1.1 to 0.7; P=0.59). Analyses of the data with adjustment for confounding factors, as well as subgroup analyses, also showed no survival benefit for either study group. CONCLUSIONS: Among patients who had an out-of-hospital cardiac arrest, we found no difference in the outcomes with a brief period, as compared with a longer period, of EMS-administered CPR before the first analysis of cardiac rhythm.

BACKGROUND: The impedance threshold device (ITD) is designed to enhance venous return and cardiac output during cardiopulmonary resuscitation (CPR) by increasing the degree of negative intrathoracic pressure. Previous studies have suggested that the use of an ITD during CPR may improve survival rates after cardiac arrest. METHODS: We compared the use of an active ITD with that of a sham ITD in patients with out-of-hospital cardiac arrest who underwent standard CPR at 10 sites in the United States and Canada. Patients, investigators, study coordinators, and all care providers were unaware of the treatment assignments. The primary outcome was survival to hospital discharge with satisfactory function (i.e., a score of ≤3 on the modified Rankin scale, which ranges from 0 to 6, with higher scores indicating greater disability). RESULTS: Of 8718 patients included in the analysis, 4345 were randomly assigned to treatment with a sham ITD and 4373 to treatment with an active device. A total of 260 patients (6.0%) in the sham-ITD group and 254 patients (5.8%) in the active-ITD group met the primary outcome (risk difference adjusted for sequential monitoring, -0.1 percentage points; 95% confidence interval, -1.1 to 0.8; P=0.71). There were also no significant differences in the secondary outcomes, including rates of return of spontaneous circulation on arrival at the emergency department, survival to hospital admission, and survival to hospital discharge. CONCLUSIONS: Use of the ITD did not significantly improve survival with satisfactory function among patients with out-of-hospital cardiac arrest receiving standard CPR.

INTRODUCTION: For effective responses to emergencies, individuals must have the ability to respond and also be willing to participate in the response. A growing body of research points to gaps in response willingness among several occupational cohorts with response duties, including the Emergency Medical Services (EMS) workforce. Willingness to respond is particularly important during an influenza or other pandemic, due to increased demands on EMS workers and the potential for workforces to be depleted if responders contract influenza or stay home to care for sick dependents. State emergency preparedness laws are one possible avenue to improve willingness to respond. Hypothesis Presence of certain state-level emergency preparedness laws (ie, ability to declare a public health emergency; requirement to create a public health emergency plan; priority access to health resources for responders) is associated with willingness to respond among EMS workers. METHODS: Four hundred twenty-one EMS workers from the National Registry of Emergency Medical Technicians' (NREMT's) mid-year Longitudinal EMT Attributes and Demographics Study (LEADS) were studied. The survey, which included questions about willingness to respond during an influenza pandemic, was fielded from May through June 2009. Survey data were merged with data about the presence or absence of the three emergency preparedness laws of interest in each of the 50 US states. Unadjusted logistic regression analyses were performed with the presence/absence of each law and were adjusted for respondents' demographic/locale characteristics. RESULTS: Compared to EMS workers in states that did not allow the government to declare a public health emergency, those in states that permitted such declarations were more likely to report that they were willing to respond during an influenza pandemic. In adjusted and unadjusted analyses, this difference was not statistically significant. Similar results were found for the other state-level emergency preparedness laws of interest. CONCLUSION: While state-level emergency preparedness laws are not associated with willingness to respond, recent research suggests that inconsistencies between the perceived and objective legal environments for EMS workers could be an alternative explanation for this study's findings. Educational efforts within the EMS workforce and more prominent state-level implementation of emergency preparedness laws should be considered as a means to raise awareness of these laws. These types of actions are important steps toward determining whether state-level emergency preparedness laws have the potential to promote response willingness among EMS workers.

OBJECTIVE: This study examines the factors associated with persistent, multi-year, and frequent emergency department (ED) use among children and young adults. METHODS: We conducted a retrospective secondary analysis using the 2012-2017 Healthcare Cost and Utilization Project State Emergency Department Databases for children and young adults aged 0-19 who visited any ED in Florida, Massachusetts, and New York. We estimated the association between persistent frequent ED use and individuals' characteristics using multivariable logistic regression models. RESULTS: Among 1.3 million patients with 1.8 million ED visits in 2012, 2.9% (37,558) exhibited frequent ED use (≥4 visits in 2012) and accounted for 10.2% (181,138) of all ED visits. Longitudinal follow-up of frequent ED users indicated that 15.4% (5770) remained frequent users periodically over the next 1 or 2 years, while 2.2% (831) exhibited persistent frequent use over the next 3-5 years. Over the 6-year study period, persistent frequent users had 31,551 ED visits at an average of 38.0 (standard deviation = 16.2) visits. Persistent frequent ED use was associated with higher intensity of ED use in 2012, public health insurance coverage, inconsistent health insurance coverage over time, residence in non-metropolitan and lower-income areas, multimorbidity, and more ED visits for less medically urgent conditions. CONCLUSIONS: Clinicians and policymakers should consider the diverse characteristics and needs of pediatric persistent frequent ED users compared to broader definitions of frequent users when designing and implementing interventions to improve health outcomes and contain ED visit costs.

OBJECTIVE: To understand shift-level determinants of emergency physician (EP) burnout, relationships were tested between EP shift demands, stress, and fatigue. METHOD: EP ( n = 16) were assessed over 114 shifts that occurred before and during the COVID-19 pandemic. Salivary cortisol (an indicator of stress) and self-reported fatigue were collected prior to and following each shift. An objective crowding score (National Emergency Department Overcrowding Scale) per shift was calculated. Shift demands were assessed at the end of each shift. RESULTS: Multilevel models revealed that shift demands, National Emergency Department Overcrowding Scale, and the pandemic were related to higher levels of end-of-shift cortisol, but not fatigue. Cortisol levels were higher for shifts with a higher number of demands, greater crowding, and during the pandemic. CONCLUSIONS: Shift demands predicted objective indicators of stress, but not self-reported fatigue. Interventions are needed to decrease stress and shift demands to reduce EP burnout.

BACKGROUND: Transfusion of blood products is life-saving and time-sensitive in the setting of acute blood-loss anemia, and is increasingly common in the emergency medical services (EMS) setting. Prehospital blood products are generally "cold-stored" at 4°C, then warmed with a portable fluid-warming system for the purpose of preventing the "lethal triad" of hypothermia, acidosis, and coagulopathy. This study aims to evaluate body temperature changes of EMS patients receiving packed red blood cells (PRBC) and/or fresh frozen plasma (FFP) when using the LifeWarmer Quantum Blood & Fluid Warming System (LifeWarmer, https://www.lifewarmer.com/). METHODS: From 1 January 2020 to 31 August 2021, patients who qualified for and received PRBC and/or FFP were retrospectively reviewed. Body-temperature homeostasis pre- and post-transfusion were evaluated with attention given to those who arrived to the emergency department (ED) hypothermic (<36°C). RESULTS: For all 69 patients analyzed, the mean initial prehospital temperature (°C) was 36.5 ± 1.0, and the mean initial ED temperature was 36.7 ± 0.6, demonstrating no statically significant change in value pre- or post-transfusion (0.2 ± 0.8, p = .09). Shock index showed a statistically significant decrease following transfusion: 1.5 ± 0.5 to 0.9 ± 0.4 (p < .001). CONCLUSION: Use of the Quantum prevents the previously identified risk of hypothermia with respect to unwarmed prehospital transfusions. The data is favorable in that body temperature did not decrease in critically ill patients receiving cold-stored blood warmed during administration with the Quantum.

The application and provision of prehospital care in disasters and mass-casualty incident response in Europe is currently being explored for opportunities to improve practice. The objective of this translational science study was to align common principles of approach and action and to identify how technology can assist and enhance response. To achieve this objective, the application of a modified Delphi methodology study based on statements derived from key findings of a scoping review was undertaken. This resulted in 18 triage, eight life support and damage control interventions, and 23 process consensus statements. These findings will be utilized in the development of evidence-based prehospital mass-casualty incident response tools and guidelines.

On September 23, 2010, the American Board of Medical Specialties (ABMS) approved emergency medical services (EMS) as a subspecialty of emergency medicine. As a result, the American Board of Emergency Medicine (ABEM) is planning to award the first certificates in EMS medicine in the fall of 2013. The purpose of subspecialty certification in EMS, as defined by ABEM, is to standardize physician training and qualifications for EMS practice, to improve patient safety and enhance the quality of emergency medical care provided to patients in the prehospital environment, and to facilitate integration of prehospital patient treatment into the continuum of patient care. In February 2011, ABEM established the EMS Examination Task Force to develop the Core Content of EMS Medicine (Core Content) that would be used to define the subspecialty and from which questions would be written for the examinations, to develop a blueprint for the examinations, and to develop a bank of test questions for use on the examinations. The Core Content defines the training parameters, resources, and knowledge of the treatment of prehospital patients necessary to practice EMS medicine. Additionally, it is intended to inform fellowship directors and candidates for certification of the full range of content that might appear on the examinations. This article describes the development of the Core Content and presents the Core Content in its entirety.

PURPOSE: To investigate the prevalence, demographic, and work associations of self-reported sleep complaints in US emergency medical technicians (EMTs) METHODS: The mailed 2005 Longitudinal Emergency Medical Technician Attributes and Demographics Study (LEADS) questionnaire was distributed to selected EMTs that included 35 sleep-related questions. Questions were adapted from previously validated sleep medicine surveys, including the Epworth Sleepiness Scale (ESS), and were used to estimate the prevalence of different sleep problems. These sleep problems were analyzed in relation to demographic, health, satisfaction, and workplace characteristics. Responses of individuals who were not working as EMTs were used as a comparison group. RESULTS: Sleep problems in working EMTs were more prevalent than in a comparison group. Seventy percent of working EMTs had at least one sleep problem. The most common sleep problem was a risk of long sleep onset disorder (50%). EMTs with tiredness-related work difficulties were more than 50% as likely to report this problem. The prevalence of excessive daytime sleepiness (ESS > 10) was 36%; 6% of the EMTs had an ESS > 16. EMTs reporting tiredness-related work difficulties were more than twice as likely to have ESS scores >10 and more than three times as likely to ESS scores >16. Symptom-defined risk of sleep apnea was present in 5%. Risks of sleep onset and maintenance disorder problems were more prevalent among those who worked longer shifts and had longer work weeks and were associated with poorer job satisfaction and poorer health. CONCLUSIONS: Severe sleep problems and severe sleepiness at a level that may contribute to health and job issues are common in US EMTs. Although breathing disorders are common, behaviorally related sleep issues are more prevalent. These data support an increased focus on sleep onset and maintenance disorders.

CONTEXT: Laboratory studies suggest that in the setting of cardiac ischemia, immediate intravenous glucose-insulin-potassium (GIK) reduces ischemia-related arrhythmias and myocardial injury. Clinical trials have not consistently shown these benefits, possibly due to delayed administration. OBJECTIVE: To test out-of hospital emergency medical service (EMS) administration of GIK in the first hours of suspected acute coronary syndromes (ACS). DESIGN, SETTING, AND PARTICIPANTS: Randomized, placebo-controlled, double-blind effectiveness trial in 13 US cities (36 EMS agencies), from December 2006 through July 31, 2011, in which paramedics, aided by electrocardiograph (ECG)-based decision support, randomized 911 (871 enrolled) patients (mean age, 63.6 years; 71.0% men) with high probability of ACS. INTERVENTION: Intravenous GIK solution (n = 411) or identical-appearing 5% glucose placebo (n = 460) administered by paramedics in the out-of-hospital setting and continued for 12 hours. MAIN OUTCOME MEASURES: The prespecified primary end point was progression of ACS to myocardial infarction (MI) within 24 hours, as assessed by biomarkers and ECG evidence. Prespecified secondary end points included survival at 30 days and a composite of prehospital or in-hospital cardiac arrest or in-hospital mortality, analyzed by intent-to-treat and by presentation with ST-segment elevation. RESULTS: There was no significant difference in the rate of progression to MI among patients who received GIK (n = 200; 48.7%) vs those who received placebo (n = 242; 52.6%) (odds ratio [OR], 0.88; 95% CI, 0.66-1.13; P = .28). Thirty-day mortality was 4.4% with GIK vs 6.1% with placebo (hazard ratio [HR], 0.72; 95% CI, 0.40-1.29; P = .27). The composite of cardiac arrest or in-hospital mortality occurred in 4.4% with GIK vs 8.7% with placebo (OR, 0.48; 95% CI, 0.27-0.85; P = .01). Among patients with ST-segment elevation (163 with GIK and 194 with placebo), progression to MI was 85.3% with GIK vs 88.7% with placebo (OR, 0.74; 95% CI, 0.40-1.38; P = .34); 30-day mortality was 4.9% with GIK vs 7.7% with placebo (HR, 0.63; 95% CI, 0.27-1.49; P = .29). The composite outcome of cardiac arrest or in-hospital mortality was 6.1% with GIK vs 14.4% with placebo (OR, 0.39; 95% CI, 0.18-0.82; P = .01). Serious adverse events occurred in 6.8% (n = 28) with GIK vs 8.9% (n = 41) with placebo (P = .26). CONCLUSIONS: Among patients with suspected ACS, out-of-hospital administration of intravenous GIK, compared with glucose placebo, did not reduce progression to MI. Compared with placebo, GIK administration was not associated with improvement in 30-day survival but was associated with lower rates of the composite outcome of cardiac arrest or in-hospital mortality.

OBJECTIVES: To determine how often out-of-hospital cardiac arrest (OHCA) patients who achieve return of spontaneous circulation (ROSC) experience rearrest during their emergency medical services (EMS) care and to analyze their arrest characteristics, including survival to hospital discharge. METHODS: A retrospective patient care record review was conducted for all treated OHCA patients between January 1, 2000, and February 28, 2008. Data were obtained from a countywide EMS patient care database that included treating EMS provider documentation and receiving hospital patient outcomes. If resuscitation was attempted, all OHCA patients, regardless of age, were included in the study. Those who achieved ROSC were identified and the number of patients who experienced rearrest was determined. Return of spontaneous circulation was defined as EMS documentation of a palpable pulse, and rearrest was defined as a change in cardiac rhythm associated with loss of a palpable pulse, regardless of duration. Cardiac arrest characteristics were analyzed using chi-square and t-test for resuscitated patients who experienced rearrest compared with those who did not. RESULTS: During the study period, OHCA resuscitation was attempted on 7,296 patients. Of these, 2,454 had field ROSC (34%; 95% confidence interval [CI]: 33%-35%). Of those who achieved ROSC, 951 experienced rearrest prior to hospital arrival (39%; 95% CI: 37%-41%). The average age of the patients who experienced rearrest was 2 years higher than those who did not experience rearrest (64 years vs. 62 years; p < 0.011). The proportion of women in the rearrest group was less than that in the non-rearrest group (40% vs. 46%; p < 0.008). Bystander-witnessed arrest rates were similar between the two groups (65% vs. 68%; p < 0.124). Fewer patients who experienced rearrest survived to hospital admission (53% vs. 85%; p < 0.000) and hospital discharge (15% vs. 35%; p < 0.000). Of those who experienced rearrest, 102 (11%) experienced rearrest while being transported. There was no difference in survival for those whose rearrests occurred prior to transport (14%) compared with those whose rearrests occurred during transport (16%) (p < 0.671). CONCLUSION: A significant number of OHCA patients who achieved field ROSC experienced rearrest prior to hospital arrival. Patients who experienced rearrest were less likely to survive.

BACKGROUND: The American Heart Association encourages trained and untrained bystanders to perform, at a minimum, chest compressions on anyone who suddenly collapses. It is possible that people who are not in cardiac arrest may receive bystander cardiopulmonary resuscitation (CPR), from which the potential for injury is unknown. OBJECTIVES: To determine the number of victims who received bystander CPR but were not in cardiac arrest and to identify any injuries resulting from receiving bystander CPR. METHODS: Retrospective review of patient care records from a countywide emergency medical services (EMS) database. All patients treated by EMS between March 2003 and February 2009 who received bystander CPR were queried. Victims who were determined not to be in cardiac arrest upon EMS personnel assessment were identified as likely not in cardiac arrest. Hospital medical records for transported patients were reviewed for injuries possibly related to CPR. Patient demographics were collected and descriptive statistics were used for analysis. RESULTS: Six hundred seventy-two incidents of bystander CPR occurred, with 77 (11.5%) cases not being identified as cardiac arrests by EMS. Twenty-three percent of the patients were less than 19 years of age. Emergency medical services arrived in less than 6 minutes for 68% of patients. Seventy-two patients were evaluable for injury; of those, 53% were admitted to the intensive care unit. One patient (1.4%) had an injury that was documented in the medical record as possibly CPR-related: rhabdomyolysis. CONCLUSIONS: Bystanders provide CPR for patients who are not in cardiac arrest at a relatively low frequency. Short-duration bystander CPR caused injury in less than 2% of victims. Our results suggest that the benefits of bystander CPR for adults who suddenly collapse outweigh the risk of injury for those not in cardiac arrest.
