IntroductionBehavioral health emergencies (BHEs) are a common patient encounter for emergency medical services (EMS) clinicians and other first responders, in particular law enforcement (LE) officers. It is critical for EMS clinicians to have management strategies for BHEs, yet relatively little information exists on best practices. In 2016, the Los Angeles County EMS Agency's Commission initiated a comprehensive evaluation of the 9-1-1 response for BHEs and developed a plan for improving the quality of care and safety for patients and first responders.MethodsA Behavioral Health Initiative Committee was assembled with broad representation from EMS, LE, health agencies, and the public. Committee objectives included: 1) produce a process map of the BHE response from the time of a 9-1-1 call to patient arrival at transport destination, 2) identify and describe the different agencies that respond, 3) describe the critical decision points in the EMS and LE field responses, 4) acquire data that quantitatively and/or qualitatively describe the services available, and 5) recommend interventions for system performance improvement.ResultsThe committee generated comprehensive process maps for the prehospital response to BHEs, articulated principles for evaluation, and described key observations of the current system including: 9-1-1 dispatch criteria are variable and often defaults to a LE response, the LE response inadvertently criminalizes BHEs, EMS field treatment protocols for BHEs (and especially agitated patients) are limited, substance use disorder treatment lacks integration, destination options differ by transporting agency, and receiving facilities' capabilities to address BHEs are variable. Recommendations for performance improvement interventions and initial implementation steps included: standardize dispatch protocols, shift away from a LE primary response, augment EMS treatment protocols for BHEs and the management of agitation, develop alternate destination for EMS transport.ConclusionThis paper describes a comprehensive performance improvement initiative in LAC-EMSA's 9-1-1 response to BHEs. The initiative included a thorough current state analysis, followed by future state mapping and the implementation of interventions to reduce LE as the primary responder when an EMS response is often warranted, and to improve EMS protocols and access to resources for BHEs.

Introduction: Behavioral health emergencies (BHEs) are a common patient encounter for emergency medical services (EMS) clinicians and other first responders, in particular law enforcement (LE) officers. It is critical for EMS clinicians to have management strategies for BHEs, yet relatively little information exists on best practices.

Subsequent to the Emergency Use Authorization (EUA) by the Food and Drug Administration, Gilead Sciences Inc. donated a supply of remdesivir to the United States government for immediate treatment of patients with COVID-19. The Los Angeles County Emergency Medical Services Agency (LAC-EMS) was tasked with the allocation. The objective of this study was to describe the process for allocation and the patients who were treated with the donated remdesivir in LAC. LAC-EMS developed a strategic plan to distribute federal allocations of remdesivir to LAC hospitals based on the proportion of patients admitted with COVID-19 at each hospital. Criteria for treatment and its duration were based on the EUA at local hospital discretion. Data were collected on patients treated from May to December 2020. Variables included characteristics (age, sex, race/ethnicity), hospital care (level of care and respiratory support at start of treatment, ventilator support, total ventilator days), and outcomes (length of intensive care (ICU) and hospital stay, survival to discharge, disposition). We compared demographics of treated patients to the overall population of hospitalized patients in LAC. LAC-EMS distributed 34,250 vials of remdesivir in 7 allocations, which treated 5,376 patients. The median age was 60 (IQR 48–70); 62% were male, 59% Hispanic, 17% White, 6% Asian, 5% Black. Prior to remdesivir, 96% of patients required respiratory support including 49% supplemental oxygen, 35% high-flow nasal cannula, 3% continuous or bilevel positive airway pressure and 9% mechanical ventilation, with one quarter of patients in the ICU. Overall, 26% of patients were mechanically ventilated during the hospitalization, median 11 days (IQR 8–23), while 41% required ICU care, median 10 days (IQR 5–19). Median length of stay for all patients was 10 days (IQR 7–18) with 4,218 patients (74%) surviving to discharge and 80% of survivors discharged home. Compared with overall hospitalized patients with COVID-19, treated patients more likely to be male and middle-aged, and less likely to be Black. LAC-EMS's strategic plan to distribute donated remdesivir to hospitals based on the number of inpatients with COVID-19 resulted in the treatment of 5,376 patients of whom 74% survived to hospital discharge.

Objectives: To determine the causes of software misinterpretation of ST elevation myocardial infarction (STEMI) compared to clinically identified STEMI to identify opportunities to improve prehospital STEMI identification.Methods: We compared ECGs acquired from July 2011 through June 2012 using the LIFEPAK 15 on adult patients transported by the Los Angeles Fire Department. Cases included patients ≥18 years who received a prehospital ECG. Software interpretation of the ECG (STEMI or not) was compared with data in the regional EMS registry to classify the interpretation as true positive (TP), true negative (TN), false positive (FP), or false negative (FN). For cases where classification was not possible using registry data, 3 blinded cardiologists interpreted the ECG. Each discordance was subsequently reviewed to determine the likely cause of misclassification. The cardiologists independently reviewed a sample of these discordant ECGs and the causes of misclassification were updated in an iterative fashion.Results: Of 44,611 cases, 50% were male (median age 65; inter-quartile range 52–80). Cases were classified as 482 (1.1%) TP, 711 (1.6%) FP, 43371 (97.2%) TN, and 47 (0.11%) FN. Of the 711 classified as FP, 126 (18%) were considered appropriate for, though did not undergo, emergent coronary angiography, because the ECG showed definite (52 cases) or borderline (65 cases) ischemic ST elevation, a STEMI equivalent (5 cases) or ST-elevation due to vasospasm (4 cases). The sensitivity was 92.8% [95% CI 90.6, 94.7%] and the specificity 98.7% [95% CI 98.6, 98.8%]. The leading causes of FP were ECG artifact (20%), early repolarization (16%), probable pericarditis/myocarditis (13%), indeterminate (12%), left ventricular hypertrophy (8%), and right bundle branch block (5%). There were 18 additional reasons for FP interpretation (<4% each). The leading causes of FN were borderline ST-segment elevations less than the algorithm threshold (40%) and tall T waves reducing the ST/T ratio below threshold (15%). There were 11 additional reasons for FN interpretation occurring ≤3 times each.Conclusion: The leading causes of FP automated interpretation of STEMI were ECG artifact and non-ischemic causes of ST-segment elevation. FN were rare and were related to ST-segment elevation or ST/T ratio that did not meet the software algorithm threshold. [ABSTRACT FROM PUBLISHER]
