Immediate Medical Care Rendered by US Law Enforcement Officers after Officer-Involved Shootings - An Open-Access Public Domain Video Analysis.

BACKGROUND: After officer-involved shootings (OIS), rapid delivery of emergency medical care is critical but may be delayed due to scene safety concerns. The purpose of this study was to describe medical care rendered by law enforcement officers (LEOs) after lethal force incidents. METHODS: Retrospective analysis of open-source video footage of OIS occurring from February 15, 2013 through December 31, 2020. Frequency and nature of care provided, time until LEO and Emergency Medical Services (EMS) care, and mortality outcomes were evaluated. The study was deemed exempt by the Mayo Clinic Institutional Review Board. RESULTS: Three hundred forty-two (342) videos were included in the final analysis; LEOs rendered care in 172 (50.3%) incidents. Average elapsed time from time-of-injury (TOI) to LEO-provided care was 155.8 (SD = 198.8) seconds. Hemorrhage control was the most common intervention performed. An average of 214.2 seconds elapsed between LEO care and EMS arrival. No mortality difference was identified between LEO versus EMS care (P = .1631). Subjects with truncal wounds were more likely to die than those with extremity wounds (P < .00001). CONCLUSIONS: It was found that LEOs rendered medical care in one-half of all OIS incidents, initiating care on average 3.5 minutes prior to EMS arrival. Although no significant mortality difference was noted for LEO versus EMS care, this finding must be interpreted cautiously, as specific interventions, such as extremity hemorrhage control, may have impacted select patients. Future studies are needed to determine optimal LEO care for these patients.

Community paramedic hospital reduction and mitigation program: study protocol for a randomized pragmatic clinical trial.

BACKGROUND: New patient-centered models of care are needed to individualize care and reduce high-cost care, including emergency department (ED) visits and hospitalizations for low- and intermediate-acuity conditions that could be managed outside the hospital setting. Community paramedics (CPs) have advanced training in low- and high-acuity care and are equipped to manage a wide range of health conditions, deliver patient education, and address social determinants of health in the home setting. The objective of this trial is to evaluate the effectiveness and implementation of the Care Anywhere with Community Paramedics (CACP) program with respect to shortening and preventing acute care utilization. METHODS: This is a pragmatic, hybrid type 1, two-group, parallel-arm, 1:1 randomized clinical trial of CACP versus usual care that includes formative evaluation methods and assessment of implementation outcomes. It is being conducted in two sites in the US Midwest, which include small metropolitan areas and rural areas. Eligible patients are ≥ 18 years old; referred from an outpatient, ED, or hospital setting; clinically appropriate for ambulatory care with CP support; and residing within CP service areas of the referral sites. Aim 1 uses formative data collection with key clinical stakeholders and rapid qualitative analysis to identify potential facilitators/barriers to implementation and refine workflows in the 3-month period before trial enrollment commences (i.e., pre-implementation). Aim 2 uses mixed methods to evaluate CACP effectiveness, compared to usual care, by the number of days spent alive outside of the ED or hospital during the first 30 days following randomization (primary outcome), as well as self-reported quality of life and treatment burden, emergency medical services use, ED visits, hospitalizations, skilled nursing facility utilization, and adverse events (secondary outcomes). Implementation outcomes will be measured using the RE-AIM framework and include an assessment of perceived sustainability and metrics on equity in implementation. Aim 3 uses qualitative methods to understand patient, CP, and health care team perceptions of the intervention and recommendations for further refinement. In an effort to conduct a rigorous evaluation but also speed translation to practice, the planned duration of the trial is 15 months from the study launch to the end of enrollment. DISCUSSION: This study will provide robust and timely evidence for the effectiveness of the CACP program, which may pave the way for large-scale implementation. Implementation outcomes will inform any needed refinements and best practices for scale-up and sustainability. TRIAL REGISTRATION: ClinicalTrials.gov NCT05232799. Registered on 10 February 2022.

Characteristics and Experiences of Women Physicians and Professionals in NAEMSP.

Introduction: One of the six guiding principles of the EMS Agenda 2050 is to foster a socially equitable care delivery system. A specific recommendation within this principle is that "local EMS leadership, educators and clinicians [should] reflect the diversity of their communities." Research has shown that women comprise a minority of emergency medicine services (EMS) field clinicians. In academic settings, women are represented at lower rates among experienced EMS faculty than within Emergency Medicine clinicians or faculty at large. The reasons for these differences are also unknown. Little data exist describing the number or experience of female physicians and professionals in EMS.Purpose: Our objective was to describe the composition and experiences of EMS physicians, researchers and professionals who participate in the Women in EMS group of the National Association of EMS Physicians (NAEMSP).Methods: We performed a cross-sectional, mixed-methods descriptive study of women belonging to the Women in EMS Committee of NAEMSP. A survey was sent to the 143 members of this group using a list-serve, and the data was collected in Redcap.Results: Seventy-four people completed the survey. Respondents were 96% female, 82% Caucasian, 11% underrepresented minorities (URM), and 7% LGBTQI. Of the 88% that are physicians, 78% are board certified in Emergency Medicine, compared to 55% in EMS. Forty-eight percent reported they received some form of mentorship. Among these respondents, a minority reported female mentorship, which was usually from a remote rather than local mentor (41% vs. 15%). Eighty-three percent of respondents had experienced some form of discrimination or harassment in their career, but only 68% reported their workplace culture discourages such behavior. Thirty-three percent of respondents report receiving unequal recognition because of gender. Thematic evaluation of the qualitative responses showed that respondents felt there were fewer barriers to mentorship and professional advancement opportunities in local work versus national engagement.Conclusions: In a survey evaluating representation of female professionals in EMS, participants reported on their career representations, and experiences of gender-based inequity within their EMS career settings. Several opportunities exist to improve diversity, equity, and inclusion for women in EMS based on our findings.

It's Time to Talk to Prehospital Providers: Feedback Disparities among Ground-Based Emergency Medical Services Providers and its Impact on Job Satisfaction.

OBJECTIVE: Performance feedback on clinical care and patient outcomes is a cornerstone of medical education, yet it remains lacking in the prehospital environment. Research seeking to establish the quantity of feedback provided to Emergency Medical Services (EMS) has been limited and studies focused on complimentary feedback or how feedback relates to EMS job satisfaction are lacking. The objectives of this study were to measure the frequency and nature of feedback received by EMS agencies and to identify the importance of receiving feedback as it relates to EMS job satisfaction. METHODS: This was an anonymous, survey-based study of twenty-nine Basic Life Support (BLS) and fifteen Advanced Life Support (ALS) agencies located in Southeastern Minnesota (USA). Descriptive statistics and Fisher exact tests were used. The study was deemed exempt by the Mayo Clinic Institutional Review Board. RESULTS: Ninety-four responses were included from nineteen different EMS agencies, including sixty-one (64.9%) paramedics and thirty-three (35.1%) emergency medical technicians (EMTs). One-half of all respondents reported that they had not received any type of feedback in the past 30 days, while another 43.6% of respondents indicated that they had only received feedback one to three times in the same time period. Twenty (60.6%) EMTs reported receiving no feedback in the past 30 days, compared with twenty-seven (44.3%) paramedics (P = .123). Of respondents receiving feedback, 65.9% reported never or rarely receiving positive reinforcing feedback and 60.6% reported never or rarely receiving constructive criticism or feedback regarding something that did not go well with patient care or transport. The majority of respondents were dissatisfied with the quantity (86.1%) and quality (73.4%) of feedback received. An overwhelming majority (93.6%) indicated that feedback on patient care or outcomes was important in influencing their overall job satisfaction. This high importance was maintained across all demographic groups. CONCLUSION: Within the cohort of survey respondents, a paucity of feedback received by EMS personnel is a source of dissatisfaction for EMS providers. Feedback on patient care strongly relates to overall job satisfaction. These findings suggest system-wide opportunities for structured feedback processes, focusing upon both quality and quantity of delivered feedback, to improve both patient care and staff satisfaction.

Use of Helicopter Emergency Medical Services in the Transport of Patients With Known or Suspected Coronavirus Disease 2019.

OBJECTIVE: Limited information exists regarding the response of helicopter emergency medical services (HEMS) programs to patients with known or suspected coronavirus disease 2019 (COVID-19). The purpose of this study was to determine changes in flight operations during the early stages of the pandemic. METHODS: A survey of the American College of Emergency Physicians Air Medical Section was conducted between May 13, 2020, and August 1, 2020. COVID-19 prevalence was defined as high versus low based on cases > 2,500 or ≤ 2,500. RESULTS: Of the 48 respondents, the majority (89.6%) reported that their patient guidelines had changed because of COVID-19; 89.6% of programs reported transporting COVID-19-positive patients, whereas 91.5% reported transporting persons under investigation. The majority of respondents reported additional training in COVID-19 airway management (79.2%) and personal protective equipment use (93.6%). Permitted aerosol-generating procedures included bilevel positive airway pressure (40.4%) and high-flow nasal oxygen (66.0%). No difference in guideline changes, positive COVID-19/persons under investigation transport restrictions, or permitted aerosol-generating procedures were noted between high- and low-prevalence settings. CONCLUSION: COVID-19 has resulted in changes to HEMS guidelines regardless of local disease prevalence. The pandemic has persisted sufficiently long that data regarding the effectiveness of guideline changes should be analyzed. In the absence of definitive data, national best practices should be developed to guide COVID-19 HEMS transport.

Best Practices in Managing Cardiac Arrest in the Emergency Department During the COVID-19 Pandemic.

Infection by severe acute respiratory syndrome coronavirus 2 has led to cardiac complications including an increasing incidence of cardiac arrest. The resuscitation of these patients requires a conscious effort to minimize the spread of the virus. We present a best-practice model based in four guiding principles: (1) reduce the risk of exposure to the entire health care team; (2) decrease the number of aerosol generating procedures; (3) use a small resuscitation team to limit potential exposure; and (4) consider early termination of resuscitative efforts.

Pediatric emergency medical services in privately insured patients: A 10-year national claims analysis.

OBJECTIVE: To characterize pediatric Emergency Medicine Service (EMS) transports to the Emergency Department (ED) using a national claims database. METHODS: We included children, 18 years and younger, transported by EMS to an ED, from 2007 to 2016 in the OptumLabs Data Warehouse. ICD-9 and ICD-10 diagnosis codes were used to categorize disease system involvement. Interventions performed were extracted using procedure codes. ED visit severity was measured by the Minnesota Algorithm. RESULTS: Over a 10-year period, 239,243 children were transported. Trauma was the most frequent diagnosis category for transport for children ≥5 years of age, 35.1% (age 6-13) and 32.7% (age 14-18). The most common diagnosis category in children <6 years of age was neurologic (29.3%), followed by respiratory (23.1%). Over 10 years, transports for mental disorders represented 15.3% in children age 14 to 18, and had the greatest absolute increase (rate difference + 10.4 per 10,000) across all diagnoses categories. Neurologic transports also significantly increased in children age 14 to 18 (rate difference + 6.9 per 10,000). Trauma rates decreased across all age groups and had its greatest reduction among children age 14 to 18 (rate difference - 6.8 per 10,000). Across all age groups, an intervention was performed in 15.6%. Most children (83.3%) were deemed to have ED care needed type of visit, and 15.8% of the transports resulted in a hospital admission. CONCLUSION: Trauma is the most frequent diagnosis for transport in children older than 5 years of age. Mental health and neurologic transports have markedly increased, while trauma transports have decreased. Most children arriving by ambulance were classified as requiring ED level of care. These changes might have significant implication for EMS personnel and policy makers.

Pediatric Prehospital Refusal of Medical Assistance: Association with Suspected Abuse or Neglect.

INTRODUCTION: Unlike adult refusal of medical assistance (RMA), pediatric refusal is not initiated by the patient. This lack of autonomy may permit neglect by the guardian through denial of necessary treatment. The purpose of the current study was to determine whether pediatric RMA was associated with suspected abuse or neglect (SAN). METHODS: This was a retrospective single EMS agency cross-sectional analysis of calls between January 1, 2011 and December 31, 2015 for patients <18 years of age resulting in RMA. Age- and complaint-matched control groups were generated from transported patients during the same time period. Recidivism was defined as 2 or more episodes of RMA involving a single patient during the study period. RESULTS: A total of 241 calls for service resulted in RMA during the study period, representing 12.7% of all pediatric calls. Information regarding SAN was available for 202 calls. Recidivism was noted in 8 patients (17 calls for service), resulting in 185 unique patients. Twenty-one RMA patients (11.4%) were identified as SAN. No difference in SAN status was noted between RMA patients and age-matched controls (21 vs. 24, p = 0.75) and complaint-matched controls (21 vs. 26, p = 0.53). No SAN was identified in the 8 recidivist patients when compared with the 177 non-recidivist patients (0 vs. 21, p = 0.60). CONCLUSIONS: Pediatric SAN patients are not uncommon users of EMS in our service area. Neither RMA nor recidivist RMA was associated with the presence of SAN within our patient population.

Simulation-based emergency medicine resident self-assessment.

BACKGROUND: Videotaped recordings of simulation-based performance may allow learners the opportunity to review, evaluate, and reflect upon their own performance. OBJECTIVES: To determine the accuracy of resident performance self-assessment after a simulation-based encounter; compare low- and high-scoring residents' abilities to evaluate their performance; and determine if video-assisted performance review improves self-assessment accuracy. METHODS: Emergency Medicine residents participated in a videotaped simulation-based assessment. Residents evaluated their performance immediately after completing simulated cases, and after reviewing the session's video. Self-ratings were compared to the faculty observers, and scores were divided based on the median. RESULTS: Seventeen residents participated, providing 270 self-ratings before, and 269 after, video review. Before video review, residents accurately graded their performance in 73.7% of the items. High- and low-scoring residents accurately self-assessed 83.9% and 62.2% of items, respectively. The odds of a high scorer accurately rating their own performance were 3.2 times that of a low scorer (95% confidence interval [CI] 1.9-5.2, p<0.001). After video review, resident self-assessments were accurate for 73.6% of the items. High scorers were accurate in their post-video self-assessment in 83.3% of the items, vs. 62.4% for low scorers. After video review, the odds of a high scorer accurately self-rating their performance were 3.0 times that of a low scorer (95% CI 2.1-4.1, p<0.001). CONCLUSIONS: Residents' abilities to self-assess vary, and performance quality may influence self-assessment. Video review did not significantly increase self-assessment accuracy. Improving self-assessment skills may assist residents in identifying practice gaps, thereby allowing them to focus their energy toward filling that gap.

The etiology and incidence of anaphylaxis in Rochester, Minnesota: a report from the Rochester Epidemiology Project.

BACKGROUND: Reported incidences of anaphylaxis range from 3.2 to 20 per 100,000 population. The incidence and trend over time has meaningful public health implications but has not been well characterized because of a lack of a standard definition and deficiencies in reporting of events. OBJECTIVE: We sought to determine the incidence and cause of anaphylaxis over a 10-year period. METHODS: We performed a population-based incidence study that was conducted in Rochester, Minnesota, from 1990 through 2000. Anaphylaxis episodes were identified on the basis of symptoms and signs of mast cell and basophil mediator release plus mucocutaneous, gastrointestinal tract, respiratory tract, or cardiovascular system involvement. RESULTS: Two hundred eleven cases of anaphylaxis were identified (55.9% in female subjects). The mean age was 29.3 years (SD, 18.2 years; range, 0.8-78.2 years). The overall age- and sex-adjusted incidence rate was 49.8 (95% CI, 45.0-54.5) per 100,000 person-years. Age-specific rates were highest for ages 0 to 19 years (70 per 100,000 person-years). Ingested foods accounted for 33.2% (70 cases), insect stings accounted for 18.5% (39 cases), medication accounted for 13.7% (29 cases), radiologic contrast agent accounted for 0.5% (1 case), "other" causes accounted for 9% (19 cases), and "unknown" causes accounted for 25.1% (53 cases). The "other" group included cats, latex, cleaning agents, environmental allergens, and exercise. There was an increase in the annual incidence rate during the study period from 46.9 per 100,000 persons in 1990 to 58.9 per 100,000 persons in 2000 (P = .03). CONCLUSION: The overall incidence rate is 49.8 per 100,000 person-years, which is higher than previously reported. The annual incidence rate is also increasing. Food and insect stings continue to be major inciting agents for anaphylaxis.

Prescriptions for self-injectable epinephrine and follow-up referral in emergency department patients presenting with anaphylaxis.

BACKGROUND: Anaphylaxis guidelines recommend that patients with a history of anaphylactic reaction should carry self-injectable epinephrine and should be referred to an allergist. OBJECTIVE: To evaluate how frequently patients dismissed from the emergency department after treatment for anaphylaxis received a prescription for self-injectable epinephrine or allergist referral. METHODS: A retrospective medical record review identified patients with anaphylaxis in a community-based study from 1990 through 2000. Records of patients with Hospital Adaptation of the International Classification of Diseases, Second Edition or International Classification of Diseases, Ninth Revision codes representing anaphylaxis were reviewed, and a random sample of patients with associated diagnoses was also reviewed. Patients who met the criteria for diagnosis of anaphylaxis were included in the study. RESULTS: Among 208 patients identified with anaphylaxis, 134 (64.4%) were seen in the emergency department and discharged home. On dismissal, 49 patients (36.6%; 95% confidence interval [CI], 28.4%-44.7%) were prescribed self-injectable epinephrine, and 42 patients (31.3%; 95% CI, 23.5%-39.2%) were referred to an allergist. Treatment with epinephrine in the emergency department (odds ratio, 3.6; 95% CI, 1.6-7.9; P = .001) and insect sting as the inciting allergen (odds ratio, 4.0; 95% CI, 1.6-10.5; P = .004) were significantly associated with receiving a prescription for self-injectable epinephrine. Patient age younger than 18 years was the only factor associated with referral to an allergist (P = .007). CONCLUSIONS: Most patients dismissed after treatment for anaphylaxis did not receive a self-injectable epinephrine prescription or allergist referral. Emergency physicians may be missing an important opportunity to ensure prompt treatment of future anaphylactic reactions and specialized follow-up care.

FAST ultrasound as an adjunct to triage using the START mass casualty triage system: a preliminary descriptive system.

OBJECTIVE: To determine whether the FAST examination might be a useful adjunct to simple triage and rapid treatment (START) in the secondary triage of mass-casualty victims already classified as delayed (Yellow). METHODS: A retrospective chart review was conducted of all adult trauma patients evaluated by the trauma surgery service at a level 1 trauma center between January 1 and December 31, 2003. Patients were retrospectively triaged to one of three START categories: immediate (Red), delayed (Yellow), or expectant (Black). The FAST results were obtained from the medical records. RESULTS: FAST results were available for 359 patients, of which 27 were classified as positive. Twenty (6.9%) of 286 patients retrospectively triaged as delayed (Yellow) had positive FAST studies. Of these, six underwent operative intervention within 24 hours of arrival. A total of 232 patients had both FAST and computed tomography (CT) studies performed, of which 19 FAST studies were inconclusive. In the remaining 213 patients, six of 27 had falsely positive studies, while 24 of 186 had falsely negative studies. CONCLUSIONS: Portable ultrasound technology might have identified 20 delayed (Yellow) patients with evidence of hemoperitoneum, thereby expediting evacuation to definitive care. However, only 30% of these patients subsequently underwent an operative intervention within 24 hours of arrival. Both over- and undertriage were significant problems. As such, the current study does not support the routine use of FAST ultrasound as a secondary triage tool.

Emergency medical service aspects of emergency cardiac care.

Prehospital intervention has the potential for significantly affecting the outcome of cardiovascular emergencies. The authors examine multiple issues in prehospital care that can streamline and improve cardiac care. Improving access to prehospital care and increasing the use of the emergency medical services (EMS) system can speed interventions to the patients. The use of ECG in the out-of-hospital setting can reduce time to definitive treatment. Issues, such as the use of public access defibrillation and interfacility transports are also discussed.
