Predictors of Non-Transport for Older Adult EMS Patients Encountered for Falls.

BACKGROUND: Emergency medical services (EMS) encounters for falls among older adults have been linked to poor outcomes when the patient is not transported by EMS to a hospital. However, little is known regarding characteristics of this patient population. Our primary objective was to describe characteristics associated with non-transport among older adult EMS patients encountered for falls. METHODS: We performed a national retrospective cross-sectional study of 9-1-1 patient contacts from the 2019 ESO Data Collaborative. We included patients who had 9-1-1 encounters for ground-level falls and were aged 60 years or older. Patients residing in congregate living facilities, interfacility transports, cardiac arrests, and suspected drowning patients were excluded. Potential predictors of non-transport included patient demographics, initial vital signs, who requested 9-1-1 service, incident location, alcohol/substance use, and urbanicity. We used multivariable logistic regression to determine associations between non-transport and potential predictors. RESULTS: We identified 195,204 EMS encounters for older adults who fell in 2019, including 27,563 (14.1%) non-transports. Most patients were female (62.4%), non-Hispanic White (85.4%), and fell at a home or residence (80.4%). Greater odds of non-transport were identified among males (OR 1.37, 95% CI 1.32-1.42) and Hispanic/Latino patients (OR 1.24, 95% CI 1.14-1.35). Older age was associated with greater odds of non-transport compared to patients aged 60-69 years (70-79 [OR 1.42, 95% CI 1.35-1.49], 80-89 [OR 1.51, 95% CI 1.42-1.59], ≥90 [OR 1.45, 95% CI 1.35-1.55]). Patients residing in Census tracts with larger percentages of the population living in poverty had lower odds of non-transport compared to those in areas with ≤5% in poverty (6-15% poverty [OR 0.82, 95% CI 0.78-0.84), 15-25% poverty [OR 0.78, 95% CI 0.73-0.82], and >25% poverty [OR 0.78, 95% CI 0.72-0.84]). CONCLUSION: Males, older age groups, and Hispanic/Latino patients had higher odds of non-transport among this population of community-dwelling adults age 60 or greater. These findings may inform development of future targeted falls-related mobile integrated health or community paramedic services and referrals to community intervention programs. Future work is needed to understand underlying patient and clinician perspectives driving non-transport decisions among these patients to better equip EMS clinicians with tools and information on tailored risk/benefit discussions.

Prehospital Fluid Administration for Suspected Sepsis in a Large EMS System: Opportunities to Improve Goal Fluid Delivery.

OBJECTIVES: Despite EMS-implemented screening and treatment protocols for suspected sepsis patients, prehospital fluid therapy is variable. We sought to describe prehospital fluid administration in suspected sepsis patients, including demographic and clinical factors associated with fluid outcomes. METHODS: A retrospective cohort of adult patients from a large, county-wide EMS system from January 2018-February 2020 was identified. Patient care reports for suspected sepsis were included, as identified by EMS clinician impression of sepsis, or keywords "sepsis" or "septic" in the narrative. Outcomes were the proportions of suspected sepsis patients for whom intravenous (IV) therapy was attempted and those who received ≥500 mL IV fluid if IV access was successful. Associations between patient demographics and clinical factors with fluid outcomes were estimated with multivariable logistic regression adjusting for transport interval. RESULTS: Of 4,082 suspected sepsis patients identified, the mean patient age was 72.5 (SD 16.2) years, 50.6% were female, and 23.8% were Black. Median (interquartile range [IQR]) transport interval was 16.5 (10.9-23.2) minutes. Of identified patients, 1,920 (47.0%) had IV fluid therapy attempted, and IV access was successful in 1,872 (45.9%). Of those with IV access, 1,061 (56.7%) received ≥500mL of fluid from EMS. In adjusted analyses, female (versus male) sex (odds ratio [OR] 0.79, 95% confidence interval [CI] 0.69-0.90), Black (versus White) race (OR 0.57, 95% CI 0.49-0.68), and end stage renal disease (OR 0.51, 95% CI 0.32-0.82) were negatively associated with attempted IV therapy. Systolic blood pressure (SBP) <90 mmHg (OR 3.89, 95% CI 3.25-4.65) and respiratory rate >20 (OR 1.90, 95% CI 1.61-2.23) were positively associated with attempted IV therapy. Female sex (OR 0.72, 95% CI 0.59-0.88) and congestive heart failure (CHF) (OR 0.55, 95% CI 0.40-0.75) were negatively associated with receiving goal fluid volume while SBP <90 mmHg (OR 2.30, 95% CI 1.83-2.88) and abnormal temperature (>100.4 F or <96 F) (OR 1.41, 95% CI 1.16-1.73) were positively associated. CONCLUSIONS: Fewer than half of EMS sepsis patients had IV therapy attempted, and of those, approximately half met fluid volume goal, especially when hypotensive and no CHF. Further studies are needed on improving EMS sepsis training and prehospital fluid delivery.

Effectiveness of a Novel Rapid Infusion Device and Clinician Education for Early Fluid Therapy by Emergency Medical Services in Sepsis Patients: A Pre-Post Observational Study.

OBJECTIVE: Emergency medical services (EMS) clinicians are tasked with early fluid resuscitation for patients with sepsis. Traditional methods for prehospital fluid delivery are limited in speed and ease-of-use. We conducted a comparative effectiveness study of a novel rapid infusion device for prehospital fluid delivery in suspected sepsis patients. METHODS: This pre-post observational study evaluated a hand-operated, rapid infusion device in a single large EMS system from July 2021-July 2022. Prior to device deployment, EMS clinicians completed didactic and simulation-based device training. Data were extracted from the EMS electronic health record. Eligible patients included adults with suspected sepsis treated by EMS with intravenous fluids. The primary outcome was the proportion of patients receiving goal fluid volume (at least 500 mL) prior to hospital arrival. Secondary outcomes included in-hospital mortality, disposition, and length of stay. Multivariable logistic regression was used to compare outcomes between 6-month pre- and post-implementation periods (July-December 2021 and February-July 2022, respectively), adjusting for patient demographics, abnormal prehospital vital signs, and EMS transport interval. RESULTS: Of 1,180 eligible patients (552 in the pre-implementation period; 628 in the post-implementation period), the mean age was 72 years old, 45% were female, and 25% were minority race-ethnicity. Median (interquartile range) fluid volume (in mL) increased between the pre- and post-implementation periods (600 [400,1,000] and 850 [500-1,000], respectively). Goal fluid volume was achieved in 70% of pre-implementation patients and 82% of post-implementation patients. In adjusted analysis, post-implementation patients were significantly more likely to receive goal fluid volume than pre-implementation patients (adjusted odds ratio (aOR) 2.00, 95% confidence interval (CI) 1.51-2.66). Pre-post in-hospital mortality was not significantly different (aOR 0.91, 95% CI 0.59-1.39). CONCLUSION: In a single EMS system, sepsis education and introduction of a rapid infusion device was associated with achieving goal fluid volume for suspected sepsis. Further research is needed to assess the clinical effectiveness of infusion device implementation to improve sepsis patient outcomes.

Telecommunicator Cardiopulmonary Resuscitation: A Policy Statement From the American Heart Association.

Every year in the United States, >350 000 people have sudden cardiac arrest outside of a hospital environment. Sudden cardiac arrest is the unexpected loss of heart function, breathing, and consciousness and is commonly the result of an electric disturbance in the heart. Unfortunately, only ≈1 in 10 victims survives this dramatic event. Early access to 9-1-1 and early cardiopulmonary resuscitation (CPR) are the first 2 links in the chain of survival for out-of-hospital cardiac arrest. Although 9-1-1 is frequently accessed, in the majority of cases, individuals with out-of-hospital cardiac arrest do not receive lay rescuer CPR and wait for the arrival of professional emergency rescuers. Telecommunicators are the true first responders and a critical link in the cardiac arrest chain of survival. In partnership with the 9-1-1 caller, telecommunicators have the first opportunity to identify a patient in cardiac arrest and provide initial care by delivering CPR instructions while quickly dispatching emergency medical services. The telecommunicator and the caller form a unique team in which the expertise of the telecommunicator is provided just in time to a willing caller, transforming the caller into a lay rescuer delivering CPR. The telecommunicator CPR (T-CPR) process, also previously described as dispatch CPR, dispatch-assisted CPR, or telephone CPR, represents an important opportunity to improve survival from sudden cardiac arrest. Conversely, failure to provide T-CPR in this manner results in preventable harm. This statement describes the public health impact of out-of-hospital cardiac arrest, provides guidance and resources to construct and maintain a T-CPR program, outlines the minimal acceptable standards for timely and high-quality delivery of T-CPR instructions, and identifies strategies to overcome common implementation barriers to T-CPR.

COVID-19 Pandemic: The Role of EMS Physicians in a Community Response Effort.

The COVID-19 pandemic is a worldwide historical event that will continue to affect nearly every aspect of ordinary life, including affecting our economic, political, and healthcare eco-systems. An effective pandemic response demands a coordinated and integrated response across community healthcare stakeholders, including Public Health and Emergency Management Officials. EMS systems are in a unique position and perform an essential role on the frontlines of COVID-19, including facilitating coordination of response efforts to COVID-19 within their communities while supporting public health mitigation efforts to slow the spread of the SARS-CoV-2. EMS physicians serve their communities at a unique intersection as clinical leaders, population health experts, and advocates. This paper examines and recommends crucial roles for EMS physician leaders as communities work together in pandemic response.

Opportunities for Emergency Medical Services Intervention to Prevent Opioid Overdose Mortality.

OBJECTIVES: The opioid crisis is a growing cause of mortality in the United States and may be mitigated by innovative approaches to identifying individuals at-risk of fatal opioid overdose. We examined Emergency Medical Services (EMS) utilization among a cohort of individuals who died from opioid overdose in order to identify potential opportunities for intervention. Methods: Individuals who died of unintentional opioid overdose in a large North Carolina county between 01/01/2014 and 12/31/2016 were studied in a retrospective cohort. Death records obtained from North Carolina Vital Records were linked to EMS patient care records obtained from the county EMS System in order to describe the EMS encounters of each decedent in the year preceding their death. Patient demographics and EMS encounters were assessed to identify encounter characteristics that may be targeted for intervention. Chi-square tests and odds ratios were used to evaluate and characterize the statistical significance of differences in EMS utilization. Results: Of the 218 individuals who died from unintentional opioid overdose in the study interval, 30% (n = 66) utilized EMS in the year before their death and 17% (n = 38) had at least one EMS encounter with documented drug or alcohol use (i.e. "drug-related encounter"). The mean age at death was 38 (range 19-74) years, 30% were female, 89% were White, and 8% were Black/African American. Factors associated with higher incidence of EMS utilization included age (P<.001), gender (P=.006), and race (P<.001). Decedents aged 56-65 had the highest EMS utilization (47%) and patients aged <25 and 25-35 had more drug-related EMS encounters (29% and 20%, respectively). The most common reasons for EMS utilization were "other medical" (27%), "non-traumatic pain" (20%), "traumatic injury" (16%), and "poisoning/drug ingestion" (14%). Drug or alcohol use was documented by EMS in 33% of all encounters and an opioid prescription was reported in 22% of encounters. Conclusions: Nearly one-third of individuals who died from accidental opioid overdose utilized EMS in the year before their death and nearly one-fifth had a drug-related encounter. EMS encounters may present an opportunity to identify individuals at-risk of opioid overdose and, ultimately, reduce overdose mortality.

2019 American Heart Association Focused Update on Advanced Cardiovascular Life Support: Use of Advanced Airways, Vasopressors, and Extracorporeal Cardiopulmonary Resuscitation During Cardiac Arrest: An Update to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

The fundamentals of cardiac resuscitation include the immediate provision of high-quality cardiopulmonary resuscitation combined with rapid defibrillation (as appropriate). These mainstays of therapy set the groundwork for other possible interventions such as medications, advanced airways, extracorporeal cardiopulmonary resuscitation, and post-cardiac arrest care, including targeted temperature management, cardiorespiratory support, and percutaneous coronary intervention. Since 2015, an increased number of studies have been published evaluating some of these interventions, requiring a reassessment of their use and impact on survival from cardiac arrest. This 2019 focused update to the American Heart Association advanced cardiovascular life support guidelines summarizes the most recent published evidence for and recommendations on the use of advanced airways, vasopressors, and extracorporeal cardiopulmonary resuscitation during cardiac arrest. It includes revised recommendations for all 3 areas, including the choice of advanced airway devices and strategies during cardiac arrest (eg, bag-mask ventilation, supraglottic airway, or endotracheal intubation), the training and retraining required, the administration of standard-dose epinephrine, and the decisions involved in the application of extracorporeal cardiopulmonary resuscitation and its potential impact on cardiac arrest survival.

2019 American Heart Association Focused Update on Systems of Care: Dispatcher-Assisted Cardiopulmonary Resuscitation and Cardiac Arrest Centers: An Update to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

Survival after out-of-hospital cardiac arrest requires an integrated system of care (chain of survival) between the community elements responding to an event and the healthcare professionals who continue to care for and transport the patient for appropriate interventions. As a result of the dynamic nature of the prehospital setting, coordination and communication can be challenging, and identification of methods to optimize care is essential. This 2019 focused update to the American Heart Association systems of care guidelines summarizes the most recent published evidence for and recommendations on the use of dispatcher-assisted cardiopulmonary resuscitation and cardiac arrest centers. This article includes the revised recommendations that emergency dispatch centers should offer and instruct bystanders in cardiopulmonary resuscitation during out-of-hospital cardiac arrest and that a regionalized approach to post-cardiac arrest care may be reasonable when comprehensive postarrest care is not available at local facilities.

Novel Use of Telemedicine by Hurricane Evacuation Shelters.

Introduction: Hurricane Florence made landfall in North Carolina as a Category 1 hurricane on September 14, 2018 causing catastrophic flooding throughout much of eastern North Carolina. Large numbers of evacuees were housed in evacuation shelters established by state emergency management and county governments. The purpose of this study was to evaluate the implementation of a telemedicine service in evacuation shelters to determine whether the presence of telemedicine could alter EMS and ED utilization. Methods: We conducted a cross-sectional study that described the EMS and Emergency Department utilization of patients housed in disaster shelters during a 12 day period following Hurricane Florence. Subjects were those shelter residents in Wake or Orange counties utilizing emergency services. Data were collected from Wake County EMS, Orange County EMS, and RelyMD, the telemedicine service utilized in the shelters. Data included subject demographics, chief complaint, case disposition, telemedicine processing times, and an after-call survey to assess satisfaction and emergency department avoidance rates. De-identified data were compiled into Excel spread sheets. Results: There were a total of 194 combined telemedicine and EMS patient encounters, including 63 EMS transports, 25 refusals, 13 referrals (Wake County EMS), and 93 telemedicine patient encounters. Of the telemedicine encounters, 64 evaluations took place in Wake County shelters and 29 evaluations in the Orange County shelter. Average patient age was 49 years old; 67% were female. Forty three patients (46%) utilized the telemedicine service for obtaining medication refills, of whom 19 (44%) indicated they would have otherwise utilized an ED to refill their medication. Forty patients (43%) indicated they would have otherwise gone to an ED for care had the service not been provided, with the needs of 33 (83%) of these patients successfully managed without evaluation in an ED. Only 9 (9.7%) patients were referred by the telemedicine service to an ED for an evaluation, with 3 (3.2%) being admitted. Conclusion: Our descriptive findings suggest telemedicine can be effectively utilized in a general population evacuation shelter to reduce EMS and ED utilization and address the medical needs of the population. Further studies should be performed to assess applicability to other disaster settings.

2018 American Heart Association Focused Update on Advanced Cardiovascular Life Support Use of Antiarrhythmic Drugs During and Immediately After Cardiac Arrest: An Update to the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

Antiarrhythmic medications are commonly administered during and immediately after a ventricular fibrillation/pulseless ventricular tachycardia cardiac arrest. However, it is unclear whether these medications improve patient outcomes. This 2018 American Heart Association focused update on advanced cardiovascular life support guidelines summarizes the most recent published evidence for and recommendations on the use of antiarrhythmic drugs during and immediately after shock-refractory ventricular fibrillation/pulseless ventricular tachycardia cardiac arrest. This article includes the revised recommendation that providers may consider either amiodarone or lidocaine to treat shock-refractory ventricular fibrillation/pulseless ventricular tachycardia cardiac arrest.

Evaluation of an Integrated Rescue Task Force Model for Active Threat Response.

OBJECTIVE: An integrated response to active threat events is essential to saving lives. Coordination of law enforcement officer (LEO) and emergency medical services (EMS) roles requires joint training, as maximizing survival is a shared responsibility. We sought to evaluate the performance of an integrated LEO-EMS Rescue Task Force (RTF) response to a simulated active shooter incident utilizing objective performance measures. METHODS: Following prior didactic training, we conducted a series of evaluation scenarios for EMS providers and patrol officers in our urban/suburban advanced life support EMS system (pop. 1,000,000). The scenario-tested command staff, LEOs tasked with neutralizing an active shooter threat, and two RTFs of LEOs and EMS providers each tasked with triage and treatment of 11 simulated casualties scattered over 2 office building floors totaling 13,000 square feet. Trained evaluators recorded performance on 30 objective data elements related to LEO-EMS operations/communication, time intervals, and trauma care. Data were analyzed using descriptive statistics and t-tests for between group comparisons. RESULTS: Over 18 days, 69 scenario events evaluated 388 EMS providers and 468 LEOs. Overall median (90th percentile) times in minutes from dispatch were: unified command established 4.1 (5.5), RTF assembled 9.4 (13.5), first victim contact 11.9 (16.5), first victim to internal casualty collection point (CCP) 16.6 (20.8), all victims ready for evacuation 21.6 (26.0). Life-saving interventions included tourniquet placed: 96% (95% CI 92-99) and LEO placed tourniquet: 88% (79-94). Clinical delays included inappropriate chest decompression: 4% (2-9) and unnecessary initial treatment: 17% (12-25). Correct operational actions included communication with LEO to ensure EMS was safe to treat: 70% (61-77) and appropriate CCP selection: 84% (74-91). Incorrect operational actions included failure to maintain protective LEO-EMS formation: 49% (45-62) and inappropriate single patient evacuation: 20% (14-28). Limitations included the lack of a pre-training control group for this novel program. CONCLUSIONS: We described the performance of an integrated LEO-EMS Rescue Task Force response to a simulated active shooter event in a large city. In general, clinical care was appropriate while operational targets can be improved. Objective measurement of response goals may be used for benchmarking and performance improvement for active threat events.

Out-of-hospital cardiac arrest outcomes with "pit crew" resuscitation and scripted initiation of mechanical CPR.

OBJECTIVE: To compare OHCA outcomes in patients managed with mechanical versus manual CPR in an EMS system with a "pit crew" approach to resuscitation and a scripted sequence for the initiation of mechanical CPR. METHODS: Through a year-long quality improvement effort we standardized the initial resuscitative efforts for OHCA, prioritizing a "pit crew" approach to high quality manual CPR, early defibrillation and basic airway management ahead of a scripted sequence for initiating mechanical CPR. We then analyzed outcomes for adult, non-traumatic OHCA attended in the following year (2016). We used a propensity score matched analysis to compare ROSC, survival to discharge, and neurologic status among patients managed with manual versus mechanical CPR while controlling for patient demographics and arrest characteristics. RESULTS: Of 444 eligible OHCAs, 217 received manual and 227 received mechanical CPR. Crude ROSC (39.2% vs. 29.1%) and survival to discharge (13.8% vs. 5.7%) were higher with manual CPR. In the propensity matched analysis (n = 176 manual CPR; 176 mechanical CPR), both ROSC (38.6% vs. 28.4%; difference: 10.2%; CI: 0.4% to 20.0%) and survival to discharge (13.6% vs. 6.8%; difference: 6.8%; CI: 0.5% to 13.3%) remained significantly higher for patients receiving manual CPR. CONCLUSIONS: In this EMS system with a standardized, "pit crew" approach to OHCA that prioritized initial high-quality initial resuscitative efforts and scripted the sequence for initiating mechanical CPR, use of mechanical CPR was associated with decreased ROSC and decreased survival to discharge.

Improving Decisions About Transport to the Emergency Department for Assisted Living Residents Who Fall.

Background: Residents of assisted living facilities who fall may not be seriously ill or injured, but policies often require immediate transport to an emergency department regardless of the patient's condition. Objective: To determine whether unnecessary transport can be avoided. Design: Prospective cohort study. Setting: One large county with a single system of emergency medical services. Participants: Convenience sample of residents in 22 assisted living facilities served by 1 group of primary care physicians. Intervention: Paramedics providing emergency medical services followed a protocol that included consulting with a physician by telephone. Measurements: The number of transports after a fall and the number of time-sensitive conditions in nontransported patients. Results: Of the 1473 eligible residents, 953 consented to participate in the study (mean age, 86 years; 76% female) and 359 had 840 falls in 43 months. The protocol recommended nontransport after 553 falls. Eleven of these patients had a time-sensitive condition. At least 7 of them received appropriate care: 4 requested and received transport despite the protocol recommendation, and 3 had minor injuries that were successfully managed on site. Three additional patients had fractures that were diagnosed by outpatient radiography. The final patient developed vomiting and diarrhea, started palliative care, and died 60 hours after the fall. At least 549 of the 553 patients (99.3% [95% CI, 98.2% to 99.8%]) with a protocol recommendation for nontransport received appropriate care. Limitation: The resources required for this program will preclude use in some locations. Conclusion: Shared decision making between paramedics and primary care physicians can prevent transport to the emergency department for many residents of assisted living facilities who fall. Primary Funding Source: None.

Measuring a Crisis: Questioning the Use of Naloxone Administrations as a Marker for Opioid Overdoses in a Large U.S. EMS System.

OBJECTIVE: The United States is currently experiencing a public health crisis of opioid overdoses. To determine where resources may be most needed, many public health officials utilize naloxone administration by EMS as an easily-measured surrogate marker for opioid overdoses in a community. Our objective was to evaluate whether naloxone administration by EMS accurately represents EMS calls for opioid overdose. We hypothesize that naloxone administration underestimates opioid overdose. METHODS: We conducted a chart review of suspected overdose patients and any patients administered naloxone in Wake County, North Carolina, from January 2013 to December 2015. Patient care report narratives and other relevant data were extracted from electronic patient care records and the resultant database was analyzed by two EMS physicians. Cases were divided into categories including "known opioid use," "presumed opioid use," "no known opioid," "altered mental status," "cardiac arrest with known opioid use," "cardiac arrest with no known opioid use," or "suspected alcohol intoxication," and then further separated based on whether naloxone was administered. Patient categories were compared by patient demographics and incident year. Using the chart review classification as the gold standard, we calculated the sensitivity and positive predictive value (PPV) of naloxone administration for opioid overdose. RESULTS: A total of 4,758 overdose cases from years 2013-15 were identified. During the same period, 1,351 patients were administered naloxone. Of the 1,431 patients with known or presumed opioid use, 57% (810 patients) received naloxone and 43% (621 patients) did not. The sensitivity of naloxone administration for the identification of patients with known or presumed opioid use was 57% (95% CI: 54%-59%) and the PPV was 60% (95% CI: 57%-63%). CONCLUSION: Among patients receiving care in this large urban EMS system in the United States, the overall sensitivity and positive predictive value for naloxone administration for identifying opioid overdoses was low. Better methods of identifying opioid overdose trends are needed to accurately characterize the burden of opioid overdose within and among communities.

Acute Crisis Care for Patients with Mental Health Crises: Initial Assessment of an Innovative Prehospital Alternative Destination Program in North Carolina.

OBJECTIVE: Emergency Departments (ED) are overburdened with patients experiencing acute mental health crises. Pre-hospital transport by Emergency Medical Services (EMS) to community mental health and substance abuse treatment facilities could reduce ED utilization and costs. Our objective was to describe characteristics, treatment, and outcomes of acute mental health crises patients who were transported by EMS to an acute crisis unit at WakeBrook, a North Carolina community mental health center. METHODS: We performed a retrospective cohort study of patients diverted to WakeBrook by EMS from August 2013-July 2014. We abstracted data from WakeBrook medical records and used descriptive statistics to quantify patient characteristics, diagnoses, length of stay (LOS), and 30-day recidivism. RESULTS: A total of 226 EMS patients were triaged at WakeBrook. The median age was 38 years, 55% were male, 58% were white, and 38% were uninsured. The most common chief complaints were suicidal ideation or self-harm (46%) and substance abuse (19%). The most common diagnoses were substance-related and addictive disorders (42%), depressive disorders (32%), and schizophrenia spectrum and other psychotic disorders (22%). Following initial evaluation, 28% of patients were admitted to facilities within WakeBrook, 40% were admitted to external psychiatric facilities, 18% were stabilized and discharged home, 5% were transferred to an ED within 4 hours for further medical evaluation, and 5% refused services. The median LOS at WakeBrook prior to disposition was 12.0 hours (IQR 5.4-21.6). Over a 30-day follow-up period, 60 patients (27%) had a return visit to the ED or WakeBrook for a mental health issue. CONCLUSIONS: A dedicated community mental health center is able to treat patients experiencing acute mental health crises. LOS times were significantly shorter compared to regional EDs. Successful broader programmatic implementation could improve care quality and significantly reduce the volume of patients treated in the ED for acute mental health disorders.

Repeated Emergency Medical Services Use by Older Adults: Analysis of a Comprehensive Statewide Database.

STUDY OBJECTIVE: The objective of this study is to characterize repeated emergency medical services (EMS) transports among older adults across a large and socioeconomically diverse region. METHODS: Using the North Carolina Prehospital Medical Information System, we analyzed the frequency of repeated EMS transports within 30 days of an index EMS transport among adults aged 65 years and older from 2010 to 2015. We used multivariable logistic regressions to determine characteristics associated with repeated EMS transport. RESULTS: During the 6-year period, EMS performed 1,711,669 transports for 689,664 unique older adults in North Carolina. Of these, 303,099 transports (17.7%) were followed by another transport of the same patient within 30 days. The key characteristics associated with an increased adjusted odds ratio of repeated transport within 30 days include transport from an institutionalized setting (odds ratio [OR] 1.42; 95% confidence interval [CI] 1.38 to 1.47), blacks compared with whites (OR 1.29; 95% CI 1.24 to 1.33), a dispatch complaint of psychiatric problems (OR 1.38; 95% CI 1.25 to 1.52), back pain (OR 1.35; 95% CI 1.26 to 1.45), breathing problems (OR 1.21; 95% CI 1.15 to 1.30), and diabetic problems (OR 1.14; 95% CI 1.06 to 1.22). Falls accounted for 15.6% of all transports and had a modest association with repeated transports (OR 1.07; 95% CI 1.00 to 1.14). CONCLUSION: More than 1 in 6 EMS transports of older adults in North Carolina are followed by a repeated transport of the same patient within 30 days. Patient characteristics and chief complaints may identify increased risk for repeated transport and suggest the potential for targeted interventions to improve outcomes and manage EMS use.

Elite Motorcycle Racing: Crash Types and Injury Patterns in the MotoGP Class.

BACKGROUND: Crashes are a small but regular feature of elite motorcycle racing. These crashes provide a novel opportunity to benchmark and analyze motorcycle crash mechanics, crash types, and associated injuries at high speeds in a cohort of riders who are well protected and in a controlled environment. PURPOSE: The purpose was to benchmark the prevalence of injuries, categorize crash subtypes, and determine associated injury patterns. METHODS: This was an institutional review board-approved, prospective observational cohort study of MotoGP riders for 1 racing season in 3 venues. Accident type was determined by race-marshal report and visual analysis of race footage for each crash. Accident types were defined as lowside (falling toward the inside of the turn), highside (falling over and toward the outside of the turn), and topside (going over the handlebars of the motorcycle). Specific injuries and hospital admission data were collected using a standardized data collection form. Basic descriptive statistics were performed on all categorical variables. We used the exact binomial test examine the association between accident type and retirement from race, transport to medical building, transport to hospital, and injuries sustained. RESULTS: Crash prevalence was 9.7 per hundred rider hours. There were 78 crashes: 58 lowsides, 13 highsides, 2 topsides, and 5 indeterminate. In the lowside group (n = 58), 19 (95% confidence interval [CI], 0.21-0.46) riders retired, 0 required emergent transportation to the track facility or to the hospital, and 1 (95% CI, <0.1-0.9) significant injury was noted. In the highside group (n = 13), 10 (95% CI, 0.46-0.95) retired, 9 (95% CI, 0.39-0.91) were transported to the track medical facility, and 3 (95% CI, 0.05-0.54) were admitted to the hospital. In the highside group, there were 7 (95% CI, 0.25-0.81) significant injuries. In the topside group, both riders were retired with 1 hospital admission. Lowside crashes had a lower rate of retirement from race, emergent transport, and significant injuries compared with highside crashes. CONCLUSIONS: Lowside crashes are lower risk than highside crashes. Most highside crashes are caused by oversteering to prevent an impending lowside crash. Strategies to reduce oversteering to prevent a lowside crash may reduce highside crashes, enhance the safety for riders in MotoGP racing, and be applicable to recreational motorcycle riding.

Double Sequential External Defibrillation in Out-of-Hospital Refractory Ventricular Fibrillation: A Report of Ten Cases.

Abstract Background. Ventricular fibrillation (VF) is considered the out-of-hospital cardiac arrest (OOHCA) rhythm with the highest likelihood of neurologically intact survival. Unfortunately, there are occasions when VF does not respond to standard defibrillatory shocks. Current American Heart Association (AHA) guidelines acknowledge that the data are insufficient in determining the optimal pad placement, waveform, or energy level that produce the best conversion rates from OOHCA with VF. Objective. To describe a technique of double sequential external defibrillation (DSED) for cases of refractory VF (RVF) during OOHCA resuscitation. Methods. A retrospective case series was performed in an urban/suburban emergency medical services (EMS) system with advanced life support care and a population of 900,000. Included were all adult OOHCAs having RVF during resuscitation efforts by EMS providers. RVF was defined as persistent VF following at least 5 unsuccessful single shocks, epinephrine administration, and a dose of antiarrhythmic medication. Once the patient was in RVF, EMS personnel applied a second set of pads and utilized a second defibrillator for single defibrillation with the new monitor/pad placement. If VF continued, EMS personnel then utilized the original and second monitor/defibrillator charged to maximum energy, and shocks were delivered from both machines simultaneously. Data were collected from electronic dispatch and patient care reports for descriptive analysis. Results. From 01/07/2008 to 12/31/2010, a total of 10 patients were treated with DSED. The median age was 76.5 (IQR: 65-82), with median resuscitation time of 51minutes (IQR: 45-62). The median number of single shocks was 6.5 (IQR: 6-11), with a median of 2 (IQR: 1-3) DSED shocks delivered. VF broke after DSED in 7 cases (70%). Only 3 patients (30%) had ROSC in the field, and none survived to discharge. Conclusion. This case series demonstrates that DSED may be a feasible technique as part of an aggressive treatment plan for RVF in the out-of-hospital setting. In this series, RVF was terminated 70% of the time, but no patient survived to discharge. Further research is needed to better understand the characteristics of and treatment strategies for RVF.

Prehospital endotracheal intubation vs extraglottic airway device in blunt trauma.

OBJECTIVE: The objective of the study is to compare outcomes in blunt trauma patients managed with prehospital insertion of an extraglottic airway device (EGD) vs endotracheal intubation (ETI). The null hypothesis was that there would be no difference in mortality for the 2 groups. METHODS: This is a retrospective study of blunt trauma patients with Glasgow Coma Scale score less than or equal to 8 transported by ground emergency medical services directly from the scene of injury to a single urban level 1 trauma center. Patients managed with only noninvasive airway techniques were excluded, leaving patients undergoing either EGD placement or ETI. Outcomes included in-emergency department (ED) traumatic arrest and hospital mortality. Multivariable logistic regression was used to control for the potential confounding effects of demographic and clinical variables. For all analyses, P < .05 was used to establish statistical significance. RESULTS: In bivariate analysis, patients managed with EGD were more likely than those managed with ETI to have an in-ED traumatic arrest (36.5% vs 17.1%; P = .005), but eventual hospital mortality did not significantly differ between the 2 groups (75.7% vs 67.1%; P = .228). After controlling for demographic and clinical characteristics, patients managed with EGD were no more likely than patients managed with ETI to experience traumatic arrest in the ED (adjusted odds ratio, 1.67; 95% confidence interval, 0.72-3.89), and there was also no difference in overall hospital mortality (adjusted odds ratio, 0.912; 95% confidence interval, 0.36-2.30). CONCLUSION: In this preliminary, retrospective analysis, we found no difference in overall survival among trauma patients managed with prehospital EGD and those managed with prehospital ETI.
