Background: First medical contact for patients with sepsis often initiates in the prehospital setting, yet limited studies have explored the EMS sepsis recognition-mortality relationship. Racial and ethnic minority patients often have worse sepsis outcomes, yet the role of prehospital recognition in this inequity has not been explored. Our objective was to describe prehospital sepsis recognition and hospital mortality, with analysis by patient race and ethnicity. Methods: Using linked EMS and hospital records from the 2021 ESO Data Collaborative, we retrospectively analyzed 9-1-1 EMS transports for adult patients with emergency department ICD-10 sepsis diagnosis codes. EMS sepsis recognition was defined as a primary or secondary sepsis impression, use of an electronic health record specialty sepsis form, or a prehospital sepsis alert. We used multivariable logistic regression to assess the association between EMS sepsis recognition and hospital mortality, adjusting for age, sex, race and ethnicity, scene socioeconomic status, and documented clinical characteristics: altered mental status, hypotension, tachypnea, tachycardia, fever. We conducted a secondary analysis of patients who were positive for the quick sequential organ failure assessment (qSOFA) using first prehospital vital signs. Results: We analyzed 20,172 records for EMS-transported patients with diagnosed sepsis. Overall, 8% of patients were Black, 8% were Hispanic, and 72% were White. Prehospital sepsis recognition was 18%. Prehospital sepsis recognition was similar across racial and ethnic groups (Black: 17.2%, Hispanic: 17.4%, White: 18.1%) and adjusted odds of sepsis recognition did not differ between racial and ethnic groups. Overall mortality was 11% (2,186). Prehospital sepsis recognition was associated with a 18% reduction in adjusted odds of mortality (OR: 0.82, 95% CI: 0.70-0.94). Of patients who were qSOFA positive in the field (n = 2,168), EMS sepsis recognition was 32% and was similar across race and ethnicities. Adjusted odds of mortality were 0.68 (95% CI: 0.53-0.88) when sepsis was recognized in the prehospital setting. Conclusion: EMS identified sepsis in fewer than one in three patients even after limiting to those positive for qSOFA, without differences by race and ethnicity. EMS sepsis recognition was associated with reduced odds of mortality; however, Black patients remained at greater odds of death suggesting additional factors that warrant investigation.

Intraosseous (IO) access is frequently utilized during the resuscitation of out-of-hospital cardiac arrest (OHCA) patients. Due to proximity to the heart and differential flow rates, the anatomical site of IO access may impact patient outcomes. Using a large dataset, we aimed to compare the outcomes of OHCA patients who received upper or lower extremity IO access during resuscitation. The ESO Data Collaborative public use research datasets were used for this retrospective study. All adult (≥18 years of age) OHCA patients with successful IO access in an upper or lower extremity were evaluated for inclusion. Patients were excluded if they had intravenous (IV) access prior to IO access, or if they had a Do Not Resuscitate order documented. Our primary outcome was return of spontaneous circulation (ROSC). Secondary outcomes included survival to discharge and survival to discharge to home. Mixed-effects multivariable logistic regression models adjusted for age, sex, etiology, witnessed status, pre-first responder cardiopulmonary resuscitation (CPR), initial electrocardiogram (ECG) rhythm, location [private/residential, public, or assisted living/institutional], and response time in addition to the primary airway management strategy (endotracheal intubation, supraglottic device, surgical airway, no advanced airway) were used to compare the outcomes of patients with upper extremity IO access to the outcomes of patients with lower extremity IO access. After application of exclusion criteria, 155,884 patients who received IO access during resuscitation remained (76% lower extremity, 24% upper extremity). Upper extremity IO access was associated with greater adjusted odds of ROSC (1.11 [1.08, 1.15]), and this finding was consistent across multiple patient subgroups. Secondary analyses suggested that upper extremity access was associated with increased survival to discharge (1.18 [1.00, 1.39]) and survival to discharge to home (1.23 [1.02, 1.48]) in comparison to lower extremity IO access. In this large prehospital dataset, upper extremity IO access was associated with a small increase in the odds of ROSC in comparison to lower extremity IO access. These data support the need for prospective investigation of the ideal IO access site during OHCA resuscitation. [ABSTRACT FROM AUTHOR]

Varying rates of complications have been reported for prehospital sedation with ketamine, and the relationship to dosing has not been studied on a large scale. We evaluated the association between prehospital ketamine dosing and rates of intubations and other adverse events in patients with behavioral emergencies. Using the 2018/2019 ESO public-use research datasets, we included all non-traumatic, adult behavioral and drug-related EMS encounters with ketamine administration. Based on consensus guidelines, we stratified patients into "above" and "at/below" the maximum dosing for sedation (2 mg/kg IV/IO or 5 mg/kg IM) using the highest single dose of ketamine given. We created propensity scores for matched subjects using 1:1 propensity score matching. Using logistic regression, we compared rates of intubation and other airway interventions, antipsychotic coadministration, improvement reported by EMS, hypoxia, hypotension, and cardiac arrest between the two groups. We included 2383 patients: 478 in the above and 1905 in the at/below dose group. Above-dose ketamine was associated with a higher rate of intubation or supraglottic airway placement (6.4% v 3.3%, OR 2.0, 95% CI 1.00–3.90). Other airway interventions were similar (40.0% v 40.0%, OR 1, 95% CI 0.80–1.30). The above-dose group also showed a higher rate of improvement noted by EMS clinicians (92.5% v 88.7%, OR 1.6, 95% CI 1.01–2.40). The rates of antipsychotic coadministration, hypoxia, hypotension, and cardiac arrest were similar between the cohorts. Patients given ketamine doses above consensus recommendations for sedation appeared more likely to receive prehospital intubation but not more likely to experience other adverse events.

Background: Injurious falls represent a significant public health burden. Research and policies have primarily focused on falls occurring indoors despite evidence that outdoor falls account for 47–58% of all falls requiring some medical attention. This study described the clinical trauma severity of indoor versus outdoor injurious falls requiring Emergency Medical Services (EMS) response. Methods: Using the 2019 National Emergency Medical Services Information System (NEMSIS) dataset, we identified the location of patients injured from falls that required EMS response. We classified injury severity using (1) the Revised Trauma Score for Triage (T-RTS): ≤ 11 indicated the need for transport to a Trauma Center; (2) Glasgow Coma Scale (GCS): ≤ 8 and 9–12 indicated severe and moderate neurologic injury; and (3) patient clinical acuity by EMS: Dead, Critical, Emergent, Low. Results: Of 1,854,909 encounters for patients with injurious falls, the vast majority occurred indoors (n = 1,596,860) compared to outdoors (n = 152,994). For patients who fell indoors vs outdoors on streets or sidewalks, the proportions were comparable for moderate or severe GCS scores (3.0% vs 3.9%), T-RTS scores indicating need for transport to a Trauma Center (5.2% vs 5.9%) and EMS acuity rated as Emergent or Critical (27.7% vs 27.1%). Injurious falls were more severe among male patients compared to females and males injured by falling on streets or sidewalks had higher percentages for moderate or severe GCS scores (5.2% vs 1.9%) and T-RTS scores indicating the need for transport to a Trauma Center (7.3% vs 3.9%) compared to falling indoors. Young and middle-aged patients who fell on streets or sidewalks had higher proportions for a T-RTS score indicating the need for Trauma Center care compared to those in this subgroup who fell indoors. Yet older patients injured by falling indoors were more likely to have a T-RTS score indicating the need for transport to a Trauma Center than older patients who fell on streets or sidewalks. Conclusions: There was a similar proportion of patients with severe injurious falls that occurred indoors and outdoors on streets or sidewalks. These findings suggest the need to determine outdoor environmental risks for outdoor falls to support location-specific interventions. [ABSTRACT FROM AUTHOR]

Asthma represents one of the most common medical conditions among children encountered by emergency medical services (EMS). While care disparities for children with asthma have been observed in other healthcare settings, limited data exist characterizing disparities in prehospital care. We sought to characterize differences in prehospital treatment and transport of children with suspected asthma exacerbations by race and ethnicity, within the context of community socioeconomic status. We conducted a multi-agency retrospective study of EMS encounters in 2019 for children (2–17 years) with asthma and wheezing using a national prehospital database. Our primary outcomes included EMS transport and prehospital bronchodilator or systemic corticosteroid administration. Scene socioeconomic status was evaluated using the social vulnerability index. We used generalized estimating equations to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95%CI) for prehospital bronchodilator use or steroid use by race and ethnicity, adjusting for age, presence of abnormal vital signs, community size, bronchodilator use prior to EMS arrival, and transport disposition. We analyzed 5,266 EMS encounters (median age 8 years). Approximately half (53%) were Black non-Hispanic and 34% were White non-Hispanic. Overall, 77% were transported by EMS. In an adjusted model, Black non-Hispanic children were 25% less likely to be transported compared to White non-Hispanic children (aOR: 0.75, 95%CI: 0.58–0.96). EMS administered at least one bronchodilator to 81% of Black non-Hispanic patients, 73% of Hispanic patients, and 68% of White, non-Hispanic patients. Relative to White non-Hispanic children, EMS bronchodilator administration was greater for Black non-Hispanic children, (aOR: 1.55, 95%CI: 1.25–1.93), after controlling for scene socioeconomic status and potential confounding variables. Systemic corticosteroids were administered in 3% of all encounters. Odds of prehospital systemic corticosteroid administration did not differ significantly by race and ethnicity. Black non-Hispanic children comprised a larger proportion of EMS encounters for asthma and were more likely to receive a bronchodilator in adjusted analyses accounting for community socioeconomic status. However, these children were less likely to be transported by EMS. These findings may reflect disease severity not manifested by abnormal vital signs, management, and other social factors that warrant further investigation. [ABSTRACT FROM AUTHOR]

Ketamine is an opioid-alternative used for analgesia in the prehospital setting. There are knowledge gaps regarding its use during emergency medical services (EMS) encounters for pediatric patients. Our objective was to compare pain reduction, adverse events, and prehospital deaths between ketamine and opioids when used for analgesia administered by any route among pediatric patients. This was a retrospective review of 9-1-1 EMS records of injured pediatric patients (≤17 years of age) who received ketamine or opioids for analgesia using the ESO Data Collaborative (calendar years 2019-2020). We excluded interfacility transfers, patients receiving both medications, those with EMS clinician impressions indicating behavioral disorders, and those who received medication to facilitate advanced airway placement. EMS narrative review was performed to confirm ketamine use was for analgesia and to identify any unplanned airway placements. We assessed pain score reduction (0–10 ordinal scale) and clinician-documented patient response (improved, unchanged, worsened, unknown). Adverse events were defined as change in vital signs (GCS, SBP, RR, SpO2), bag valve mask ventilation alone, or death. Descriptive statistics were calculated to compare outcomes between groups. Overall, 9,223 patients were included, 190 (2.1%) received ketamine and 9,033 (97.9%) received opioids. Mean age in years was 12.8 [SD 4.0] for ketamine and 12.7 [SD 4.0] for opioids. Patients in both groups experienced pain reduction, and more patients receiving ketamine had EMS clinician reported improvement (93.2% vs. 87.9%, p = 0.03). Ketamine was associated with a greater average reduction in pain score than opioids (mean difference: −4.4 [SD 3.5], and −3.1 [SD 2.8], p < 0.001). Adverse events were rare with few patients receiving ventilatory support following the use of ketamine or opioids, (0, [SD 0.0%] vs. 6 [SD 0.1%], p = 1). There were no unplanned airway placements or prehospital deaths identified. We identified similar high rates of pain reduction and rare adverse events among pediatric patients who received ketamine or opioids. A greater pain reduction was noted among patients administered ketamine. Intubation as a result of medication administration did not occur and need for ventilatory assistance was rare.

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. 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. 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]). 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.

Prior studies examining prehospital characteristics related to return of spontaneous circulation (ROSC) in pediatric out-of-hospital cardiac arrest (OHCA) are limited to structured data. Natural language processing (NLP) could identify new factors from unstructured data using free-text narratives. The purpose of this study was to use NLP to examine EMS clinician free-text narratives for characteristics associated with prehospital ROSC in pediatric OHCA. This was a retrospective analysis of patients ages 0–17 with OHCA in 2019 from the ESO Data Collaborative. We performed an exploratory analysis of EMS narratives using NLP with an a priori token library. We then constructed biostatistical and machine learning models and compared their performance in predicting ROSC. There were 1,726 included EMS encounters for pediatric OHCA; 60% were male patients, and the median age was 1 year (IQR 0–9). Most cardiac arrest events (61.3%) were unwitnessed, 87.3% were identified as having medical causes, and 5.9% had initial shockable rhythms. Prehospital ROSC was achieved in 23.1%. Words most positively correlated with ROSC were "ROSC" (r = 0.42), "pulse" (r = 0.29), "drowning" (r = 0.13), and "PEA" (r = 0.12). Words negatively correlated with ROSC included "asystole" (r = −0.25), "lividity" (r = −0.14), and "cold" (r = −0.14). The terms "asystole," "pulse," "no breathing," "PEA," and "dry" had the greatest difference in frequency of appearance between encounters with and without ROSC (p < 0.05). The best-performing model for predicting prehospital ROSC was logistic regression with random oversampling using free-text data only (area under the receiver operating characteristic curve 0.92). EMS clinician free-text narratives reveal additional characteristics associated with prehospital ROSC in pediatric OHCA. Incorporating those terms into machine learning models of prehospital ROSC improves predictive ability. Therefore, NLP holds promise as a tool for use in predictive models with the goal to increase evidence-based management of pediatric OHCA. [ABSTRACT FROM AUTHOR]

Burnout has detrimental consequences for health care organizations, clinicians, and the quality of care that patients receive. Prior work suggests that workplace incivility (negative interpersonal acts) contributes to burnout. While workplace incivility is linked to EMS practitioner job dissatisfaction, absenteeism, and planned attrition, the relationship between workplace incivility and burnout has not been evaluated among EMS practitioners. This study aimed to characterize the prevalence and association of burnout and workplace incivility among EMS practitioners. A cross-sectional survey of EMS personnel in King County, Washington was performed in January to March of 2021 with burnout as the primary outcome and workplace incivility as a secondary outcome. Multivariable logistic regression was used to evaluate associations between outcomes and EMS practitioner factors that included age, sex, race/ethnicity, years of EMS experience, and current job role. 835 completed surveys were received (response rate 25%). The prevalence of burnout was 39.2%. Women were more likely to have burnout than men (59.3% vs. 33.7%, aOR 2.2, 95% CI 1.3–3.7). Workplace incivility was experienced weekly by 32.1% of respondents, with women more likely to experience incivility compared to men (41.9% vs. 27.2%, aOR 2.0, 95% CI 1.2–3.3). Respondents who experienced frequent workplace incivility were more likely to have burnout than those who did not experience frequent incivility (61.9% vs. 38.1%, OR 4.0, 95% CI 3.0–5.5). The prevalence of burnout and workplace incivility were concerning among EMS practitioners, with women more likely to experience both compared to men. EMS practitioners who experienced frequent workplace incivility were also more likely to have burnout than those who did not experience frequent incivility. [ABSTRACT FROM AUTHOR]

Introduction: Information regarding prehospital ketamine use in the pediatric population is limited as existing literature focuses primarily on critical care and air transport. Our objective was to describe patient characteristics among pediatric EMS patients who received ketamine. Secondarily, we assessed effectiveness, deviation from recommended dosing, and adverse outcomes of pediatric EMS patients who received ketamine. Methods: We conducted a retrospective data review of records from the ESO Data Collaborative for all 9-1-1 transports of pediatric patients (≤ 18 years of age) who received ketamine from 2019-2020. We categorized EMS primary impressions as a proxy for medication indication. We defined effectiveness as paramedic-identified clinical improvement, and pain relief as decrease in pain score ≥2 points between initial and final recording. Descriptive statistics were used to summarize clinical characteristics. Non-parametric Wilcoxon signed-rank test was used to assess change in pain score. Results: Out of 422,968 ground-ambulance pediatric patients, 1,291 received ketamine. They were predominately male (842, 65.2%), teenagers (median age 16, IQR: 13-17), Caucasian (810, 62.7%), and from urban areas (1,041, 80.6%). The most common EMS impressions were related to injuries (810, 62.7%) and behavior disorders (281, 21.8%). Only 980/1,291 (75.9%) had weights and identifiable routes recorded. Most patients (960, 74.4%) received single doses of ketamine, with EMS clinicians reporting improvement in 855 (89.1%) of 960 patients. Among non-behavioral emergency patients, 727/1,010 (72.0%) had pain scores recorded. Pain scores decreased significantly from a median of 8 (IQR: 4-10) to 2 (IQR: 0-6) (p < 0.001) with 59% (429) of 727 patients reporting pain score reductions of 2 or more points. Desaturation (<90% SpO2) events were noted to be minimal (1.8%). A small number (28, 2.2%) received positive pressure ventilation without advanced airway placement. No prehospital deaths were documented. Conclusion: In this large review of pediatric prehospital ketamine use, ketamine was primarily used for analgesia, but was frequently used for other indications. Most patients were observed to improve after ketamine use, with most injured patients reporting decreases in pain scores. We observed few significant adverse events related to ketamine use in this population. [ABSTRACT FROM AUTHOR]

Social determinants of health (SDOH) influence access to health care and are associated with inequities in patient outcomes, yet few studies have explored SDOH among pediatric EMS patients. The objective of this study was to examine the presence of SDOH in EMS clinician free text notes and quantify the association of SDOH with EMS pediatric transport decisions. This was a retrospective analysis of primary 9-1-1 responses for patients ages 0–17 years from the 2019 ESO Data Collaborative research dataset. We excluded cardiac arrests and patients in law enforcement custody. Using natural language processing (NLP) we extracted the following SDOH categories: income insecurity, food insecurity, housing insecurity, insurance insecurity, poor social support, and child protective services. Univariate and multivariable associations between the presence of SDOH in EMS records and EMS transport decisions were assessed using logistic regression. We analyzed 325,847 pediatric EMS encounters, of which 35% resulted in non-transport. The median age was 10 years and 52% were male. Slightly over half (53%) were White, 31% were Black, and 11% were Hispanic. Child protective services (n = 2,620) and housing insecurity (n = 1,136) were the most common SDOH categories found in the EMS free text narratives. In the multivariable model, child protective services involvement (odds ratio (OR)=2.04 [95% confidence interval (CI) 1.84–2.05]), housing insecurity (OR = 1.46 [95% CI 1.26–1.70]), insurance security (OR = 2.44 [95% CI 1.93–3.09]), and poor social support (OR = 10.48 [95% CI 1.42–77.29]) were associated with greater odds of EMS transport. SDOH documentation in the EMS narrative was rare among pediatric encounters; however, children with documented SDOH were more likely to be transported. Additional exploration of the root causes and outcomes associated with SDOH among children encountered by EMS are warranted. [ABSTRACT FROM AUTHOR]

Background: Falls are a common cause of injury with significantly associated medical costs yet public health surveillance of injuries from falls is underdeveloped. In addition, the epidemiologic understanding of outdoor falls, which have been reported to account for 47% of all injurious falls, is scant. Here we present methods to use emergency medical services (EMS) data as a public health surveillance tool for fall injuries, including those that occur secondary to syncope and heat illness, with a focus on the scope and epidemiology of outdoor fall injuries. Methods: Using the 2019 National Emergency Medical Services Information System (NEMSIS) data, we developed an approach to identify EMS encounters for fall injuries, syncope and heat illness. NEMSIS variables used in our algorithm included the EMS respondent's impression of the encounter, the reported major symptoms and the cause of injury. With these data we identified injuries from falls and, using the NEMSIS data on the location of the encounter, we identified fall injuries as occurring indoors or outdoors. We present the descriptive epidemiology of the identified patients. Results: There were 1,854,909 injuries from falls that required an EMS response identified in the NEMSIS data, with 4% of those injuries secondary to episodes of syncope (n = 73,126) and heat illness. Sufficient data were available from 94% of injurious falls that they could be assigned to indoor or outdoor locations, with 9% of these fall injuries occurring outdoors. Among fall injuries identified as occurring outdoors, 85% occurred on streets and sidewalks. Patient age was the primary sociodemographic characteristic that varied by location of the injurious fall. Sixty-six percent of fall injuries that occurred indoors were among those age 65 years or older, while this figure was 34% for fall injuries occurring outdoors on a street or sidewalk. Conclusion: The occurrence of outdoor fall injuries identified in the NEMSIS data were substantially lower than reported in other data sets. However, numerically fall injuries occurring outdoors represent a substantial public health burden. The strengths and weaknesses of using this approach for routine public health surveillance of injuries from falls, syncope and heat illness are discussed. [ABSTRACT FROM AUTHOR]

Background: The Centers for Disease Control and Prevention Guidelines for Field Triage of Injured Patients drive the destination decision for millions of emergency medical services (EMS)-transported trauma patients annually, yet limited information exists regarding performance and relationship with patient outcomes as a whole. Objective: To evaluate the association of positive findings on Centers for Disease Control and Prevention Guidelines for Field Triage of Injured Patients with hospitalization and mortality. Methods: This retrospective study included all 911 responses from the 2019 ESO Data Collaborative research dataset with complete Centers for Disease Control and Prevention Guidelines for Field Triage of Injured Patients and linked emergency department dispositions, excluding children and cardiac arrests prior to EMS arrival. Patients were categorized by Centers for Disease Control and Prevention Guidelines for Field Triage of Injured Patients step(s) met. Outcomes were hospitalization and emergency department or inhospital mortality. Results: There were 86,462 records included: n = 65,967 (76.3%) met no criteria, n = 16,443 (19.0%) met one step (n = 1,571 [9.6%] vitals, n = 1,030 [6.3%] anatomy of injury, n = 993 [6.0%] mechanism of injury, and n = 12,849 [78.1%] special considerations), and n = 4,052 (4.7%) met multiple. Compared with meeting no criteria, hospitalization odds increased threefold for vitals (odds ratio [OR]: 3.07, 95% confidence interval [CI]: 2.77–3.40), fourfold for anatomy of injury (OR: 3.94, 95% CI: 3.48–4.46), twofold for mechanism of injury (OR: 2.00, 95% CI: 1.74–2.29), or special considerations (OR: 2.46, 95% CI: 2.36–2.56). Hospitalization odds increased ninefold when positive in multiple steps (OR: 8.97, 95% CI: 8.37–9.62). Overall, n = 84,473 (97.7%) had mortality data available, and n = 886 (1.0%) died. When compared with meeting no criteria, mortality odds increased 10-fold when positive in vitals (OR: 9.58, 95% CI: 7.30–12.56), twofold for anatomy of injury (OR: 2.34, 95% CI: 1.28–4.29), or special considerations (OR: 2.10, 95% CI: 1.71–2.60). There was no difference when only positive for mechanism of injury (OR: 0.22, 95% CI: 0.03–1.54). Mortality odds increased 23-fold when positive in multiple steps (OR: 22.7, 95% CI: 19.7–26.8). Conclusions: Patients meeting multiple Centers for Disease Control and Prevention Guidelines for Field Triage of Injured Patients steps were at greater risk of hospitalization and death. When meeting only one step, anatomy of injury was associated with greater risk of hospitalization; vital sign criteria were associated with greater risk of mortality. [ABSTRACT FROM AUTHOR]

Background: A standardized objective measure of prehospital patient risk of hospitalization or death is needed. The Rapid Emergency Medicine Score (REMS), a validated risk-stratification tool, has not been widely tested for prehospital use. This study's objective was to assess predictive characteristics of initial prehospital REMS for ED disposition and overall patient mortality. Methods: This retrospective analysis used linked prehospital and hospital data from the national ESO Data Collaborative. All 911 responses from 1/1/2019–12/31/2019 were included. REMS (0–26) was calculated using age and first prehospital values for: pulse rate, mean arterial pressure, respiratory rate, oxygen saturation, and Glasgow Coma Scale. Non-transports, patients <18 and cardiac arrests prior to EMS arrival were excluded. The primary outcome was ED disposition, dichotomized to discharge versus admission, transfer, or death. The secondary outcome was overall survival to discharge (ED or inpatient). Transfers and records without inpatient disposition were excluded from the secondary analysis. Predictive ability was assessed using area under the receiver operating curve (AUROC). Optimal REMS cut points were determined using test characteristic curves. Univariable logistic regression modeling was used to quantify the association between initial prehospital REMS and each outcome. Results: Of 579,505 eligible records, 94,640 (16%) were excluded due to missing data needed to calculate REMS. Overall, 62% (n = 298,223) of patients were discharged from the ED, 36% (n = 175,212) were admitted, 2% (n = 10,499) were transferred, and 0.2% (n = 931) died in the ED. A REMS of 5 or lower demonstrated optimal statistical prediction for ED discharge versus not discharged (admission/transfer/death) (AUROC: 0.68). Patients with initial prehospital REMS of 5 or lower showed a three-fold increase in odds of ED discharge (OR: 3.28, 95%CI: 3.24–3.32). Of the 457,226 patients included in overall mortality analysis, >98% (n = 450,112) survived. AUROC of initial prehospital REMS for overall mortality was 0.79. A score 7 or lower was statistically optimal for predicting survival. Initial prehospital REMS of 7 or lower was associated with a five-fold increase in odds of overall survival (OR:5.41, 95%CI:5.15–5.69). Conclusion: Initial prehospital REMS was predictive of ED disposition and overall patient mortality, suggesting value as a risk-stratification measure for EMS agencies, systems and researchers.

Various screening tools, ranging in complexity, have been developed to predict large vessel occlusion (LVO) stroke in the prehospital setting. Our objective was to determine whether newly-developed LVO stroke scales offer a clinically-meaningful advantage over the Cincinnati Prehospital Stroke Scale (CPSS). We retrospectively analyzed prehospital patient care records linked with hospital data from 151 EMS agencies in the United States, between January 1, 2018 and December 31, 2018. We compared the CPSS to the Rapid Arterial Occlusion Evaluation (RACE), Los Angeles Motor Scale (LAMS), and the Vision, Aphasia, Neglect (VAN) assessment for LVO prediction. For each stroke scale, we used the intersection of sensitivity and specificity curves to determine optimal prediction cut-points. We used area under the ROC curve and 95% confidence intervals to assess for differences in discriminative ability between scales. We identified 13,596 prehospital records with one or more documented stroke scales of interest. Among these, 4,228 patients were diagnosed with stroke. Over half (57%, n = 2,415) of patients diagnosed with stroke experienced an acute ischemic stroke. Of patients with ischemic stroke, 26% (n = 628) were diagnosed with LVO. A CPSS score of 2 or higher demonstrated sensitivity = 69% and specificity = 78% for LVO. A RACE score of 4 or higher demonstrated sensitivity = 63%, specificity = 73%. A LAMS score of 3 or higher demonstrated sensitivity = 63%, specificity = 72% and a positive VAN score demonstrated sensitivity = 86%, specificity = 65%. Comparing the area under the ROC curve for each scale revealed no statistically significant differences in discriminative ability for LVO stroke. In this large sample of real-world prehospital patient encounters, the CPSS demonstrated similar predictive performance characteristics compared to the RACE, LAMS, and VAN for detecting LVO stroke. Prior to implementing a specific screening tool, EMS agencies should evaluate ease of use and associated implementation costs. Scored 0–3, the simple, widely-used CPSS may serve as a favorable prehospital screening instrument for LVO detection with a cut-point of 2 or higher maximizing the tradeoff between sensitivity and specificity.

Background: Incivility, defined as negative interpersonal acts that violate workplace and social norms, has been linked to negative outcomes in healthcare settings. A minimal amount is known regarding workplace incivility among emergency medical services (EMS) professionals. Our objectives were to (1) evaluate the prevalence of incivility and factors associated with experiencing workplace incivility; (2) describe the association between incivility and workforce-reducing factors (stress, career satisfaction, turnover intentions, and workplace absences); and (3) quantify the association between incivility and the organizational culture of an EMS agency. Methods: A random sample of 38,000 nationally-certified EMS professionals received an electronic questionnaire with an EMS-adapted Workplace Incivility Scale, the Competing Values Framework organizational culture scale, and factors that may negatively impact the EMS workforce. All completed surveys from nonmilitary EMS professionals currently providing patient care at the EMT level or higher were included in these analyses. We constructed multivariable logistic regression models (OR, 95% CI) to identify factors associated with experiencing workplace incivility and to examine the associations between experiencing incivility and workforce-reducing factors. We calculated univariable odds ratios to assess the association between organizational culture type and incivility. Results: A total of 3,741 EMS professionals responded to the survey (response rate =10.3%), with 2,815 (75.2%) meeting inclusion criteria. Incivility from supervisors or coworkers was experienced at least once a week by 47.4% of respondents. Factors associated with increased odds of experiencing incivility included female sex, AEMT/paramedic certification level, increasing years of EMS experience, service types other than 9-1-1 response, and higher weekly call volumes. Exposure to regular incivility was associated with increased odds of dissatisfaction with EMS, a main EMS job or a main supervisor; moderate or higher stress levels; intent to leave one's job and EMS in the next 12 months; and 10 or more workplace absences in the past 12 months. The organizational culture type "market" was associated with the greatest odds of incivility. Conclusions: Nearly half of respondents experienced incivility once a week or more, and incivility was associated with potential workforce-reducing factors. Further research is needed to understand how organizational climate and interpersonal behaviors in the workplace affect the EMS workforce. [ABSTRACT FROM AUTHOR]

Objectives: Emergency medical services (EMS) professionals often work long hours at multiple jobs and endure frequent exposure to traumatic events. The stressors inherent to the prehospital setting may increase the likelihood of experiencing burnout and lead providers to exit the profession, representing a serious workforce and public health concern. Our objectives were to estimate the prevalence of burnout, identify characteristics associated with experiencing burnout, and quantify its relationship with factors that negatively impact EMS workforce stability, namely sickness absence and turnover intentions. Methods: A random sample of 10,620 emergency medical technicians (EMTs) and 10,540 paramedics was selected from the National EMS Certification database to receive an electronic questionnaire between October, 2015 and November, 2015. Using the validated Copenhagen Burnout Inventory (CBI), we assessed burnout across three dimensions: personal, work-related, and patient-related. We used multivariable logistic regression modeling to identify burnout predictors and quantify the association between burnout and our workforce-related outcomes: reporting ten or more days of work absence due to personal illness in the past 12 months, and intending to leave an EMS job or the profession within the next 12 months. Results: Burnout was more prevalent among paramedics than EMTs (personal: 38.3% vs. 24.9%, work-related: 30.1% vs. 19.1%, and patient-related: 14.4% vs. 5.5%). Variables associated with increased burnout in all dimensions included certification at the paramedic level, having between five and 15 years of EMS experience, and increased weekly call volume. After adjustment, burnout was associated with over a two-fold increase in odds of reporting ten or more days of sickness absence in the past year. Burnout was associated with greater odds of intending to leave an EMS job (personal OR:2.45, 95% CI:1.95-3.06, work-related OR:3.37, 95% CI:2.67-4.26, patient-related OR: 2.38, 95% CI:1.74-3.26) or the EMS profession (personal OR:2.70, 95% CI:1.94-3.74, work-related OR:3.43, 95% CI:2.47-4.75, patient-related OR:3.69, 95% CI:2.42-5.63). Conclusions: The high estimated prevalence of burnout among EMS professionals represents a significant concern for the physical and mental well-being of this critical healthcare workforce. Further, the strong association between burnout and variables that negatively impact the number of available EMS professionals signals an important workforce concern that warrants further prospective investigation.

Objective: Inadequate staffing of agencies, increasing attrition rates, and frequent turnover of personnel make employee retention an ongoing concern for Emergency Medical Services (EMS). Faced with increasing demand for EMS, understanding the causes underlying turnover is critical. The objectives of this study were to describe the proportion of individuals that left EMS, likelihood of returning to the profession, and key factors contributing to the decision to leave EMS. Methods: This was a cross-sectional study of nationally-certifiedEMS professionalswho left EMS. Respondents to a census survey who reported not practicing EMS were directed to a subsection of items regarding their choice to leave EMS. Demographic and employment characteristics, likelihood of returning to EMS, and factors influencing the decision to leave EMS were assessed. Descriptive and comparative statistics (Chi-square and nonparametric test of trend [p-trend]) and univariable odds ratios were calculated. Results: The overall response rate for the full survey was 10% (n = 32,114). A total of 1247 (4%) respondents reported leaving the profession and completed the exit survey. The majority (72%) reported that they will likely return to EMS. A stepwise decrease in the reported likelihood of returning was seen with increasing years of EMS experience (e.g., 2 or less years of experience: 83%; 16 or more years: 52%; ptrend < 0.001) andmonths away from EMS (e.g., 0-2 months: 89%; more than 12 months: 57%; p-trend < 0.001). The most common factors reported to influence the decision to leave EMS included desire for better pay/benefits (65%), decision to pursue further education (60%), dissatisfaction with organization's management (54.7%), and desire for career change (54.1%). Conclusion: This cross-sectional study found an attrition rate of approximately 4% among nationally certified EMS professionals; however, the majority reported that they intended to return to the EMS profession. Intention to return to EMS decreased as years of experience and months away from the profession increased. Important factors in the decision to leave EMSincluded a desire for better pay and benefits and the decision to pursue further education. Targeting the factors identified as important in this study should be a priority for key stakeholders in improving recruitment and retention of EMS professionals. [ABSTRACT FROM AUTHOR]

Introduction: Feedback to EMS professionals is a critical component for optimizing patient care and outcomes in the prehospital setting. There is a paucity of data concerning the feedback received by prehospital providers. Objectives: The objective of this study was to describe the prevalence of feedback received by EMS professionals in the past 30 days including the types, sources, modes, and utility of feedback. The secondary objective was to identify factors associated with receiving any feedback and, specifically, feedback regardingmedical care provided. Methods: This was a crosssectional survey examining currently practicing nationally certified EMS patient care providers (EMT or higher) in non-military and non-tribal settings. Data were collected on provider characteristics along with feedback received. Descriptive statistics were calculated, and multivariable logistic regression models were constructed to assess the relationship between EMS provider characteristics and receiving feedback. A non-respondent survey was administered to assess for non-response bias. Results: Responses from 32,314 EMS providers were received (response rate = 10.4%) with 15,766 meeting inclusion criteria. In the 30 days preceding the survey, 69.4% (n = 10,924) of respondents received at least one type of feedback with 54.7% (n = 8,592) reporting receiving medical care feedback. Multivariable logistic regression modeling indicated that higher certification level, fewer years of experience in EMS, working for a hospital-based agency, air medical service, and higher weekly call volumes were significantly associated with increased odds of having received at least one type of feedback, and specifically medical care feedback. Additionally, providing primarily medical/convalescent transport and more years of EMS experience were significantly associated with decreased odds of receiving feedback. Conclusion: Feedback to EMS providers is critical to improving prehospital care. In this study, nearly a third of providers did not receive any feedback in a 30-day period, and nearly half reported not receiving medical care feedback. Disparities in the frequency of feedback exist between different provider levels and service settings, while reported feedback decreased with years of experience in the profession. Future work is needed to assess the content of feedback and role in improving patient care and safety. [ABSTRACT FROM AUTHOR]

Background: Teamwork is critical for patient and provider safety in high-stakes environments, including the setting of prehospital emergency medical services (EMS). Objective: We sought to describe the components of team leadership and team membership on a single patient call where multiple EMS providers are present. Methods: We conducted a two-day focus group with nine subject matter experts in crew resource management (CRM) and EMS using a structured nominal group technique (NGT). The specific question posed to the group was, "What are the specific components of team leadership and team membership on a single patient call where multiple EMS providers are present?" After round-robin submission of ideas and in-depth discussion of the meaning of each component, participants voted on the most important components of team leadership and team membership. Results: Through the NGT process, we identified eight components of team leadership: a) creates an action plan; b) communicates; c) receives, processes, verifies, and prioritizes information; d) reconciles incongruent information; e) demonstrates confidence, compassion, maturity, command presence, and trustworthiness; f) takes charge; g) is accountable for team actions and outcomes; and h) assesses the situation and resources and modifies the plan. The eight essential components of team membership identified included: a) demonstrates followership, b) maintains situational awareness, c) demonstrates appreciative inquiry, d) does not freelance, e) is an active listener, f) accurately performs tasks in a timely manner, g) is safety conscious and advocates for safety at all times, and h) leaves ego and rank at the door. Conclusions: This study used a highly structured qualitative technique and subject matter experts to identify components of teamwork essential for prehospital EMS providers. These findings and may be used to help inform the development of future EMS training and assessment initiatives. [ABSTRACT FROM AUTHOR]

Objective: Describe prehospital Emergency Medical Services (EMS) providers' beliefs regarding spinal precautions for pediatric trauma transport.Methods: We randomly surveyed nationally certified EMS providers. We assessed providers' beliefs about specific precautions, and preferred precautions given a child's age (0–4 or 5–18 years) and presence of specific cervical spine injury (CSI) risk factors.Results: We received 5,400 responses (17%). Most were Paramedics (36%) or EMTs (22%) and worked at fire-based services (42%). A total of 47% endorsed responding to pediatric calls more than once per month. Consensus beliefs (>66% agreement) were that rigid cervical collars (68%) and long backboards with soft conforming surfaces (79%) maintain an injured pediatric spine in optimal position. Only 39% believed in the utility of the rigid long backboard to protect the pediatric spine. For most risk factors in both age categories, a rigid cervical collar with a long backboard with a soft conforming surface was the most common response (28–40% depending on age group and risk factor); however, there were no consensus beliefs. Provider-level experience, working as a patient care provider, less education, and parent status were associated with endorsing the rigid cervical collar. Factors associated with endorsing the rigid long backboard included provider level, working as a patient care provider, low pediatric call volume, and less education.Conclusions: EMS providers believe that rigid cervical collars and long backboards with soft conforming surfaces provide optimal spinal precautions. There were no consensus beliefs, however, for use of particular precautions based on age and risk factors. [ABSTRACT FROM PUBLISHER]
