Women who suffer an out-of-hospital cardiac arrest receive bystander cardiopulmonary resuscitation (CPR) less often than men. Understanding public perceptions of why this occurs is a necessary first ...step toward equitable application of this potentially life-saving intervention.
We conducted a national survey of members of the public using Mechanical Turk, Amazon's crowdsourcing platform, to determine reasons why women might receive bystander CPR less often than men. Eligible participants were adults (≥18 years) located in the United States. Responses were excluded if the participant was not able to define CPR correctly. Participants were asked to answer the following free-text question: "Do you have any ideas on why women may be less likely to receive CPR than men when they collapse in public?" Descriptive statistics were used to define the cohort. The free-text response was coded using open coding, and major themes were identified via classical content analysis.
In total, 548 subjects were surveyed. Mean age was 38.8 years, and 49.8% were female. Participants were geographically distributed as follows: 18.5% West, 9.2% Southwest, 22.0% Midwest, 27.5% Southeast, and 22.9% Northeast. After analysis, 3 major themes were detected for why the public perceives that women receive less bystander CPR. They include the following: (1) sexualization of women's bodies; (2) women are weak and frail and therefore prone to injury; and (3) misperceptions about women in acute medical distress. Overall, 41.9% (227) were trained in CPR while 4.4% reported having provided CPR in a medical emergency.
Members of the general public perceive fears about inappropriate touching, accusations of sexual assault, and fear of causing injury as inhibiting bystander CPR for women. Educational and policy efforts to address these perceptions may reduce the sex differences in the application of bystander CPR.
To evaluate the frequency of EMS protocol non-adherence during pediatric asthma encounters and its association with emergency department (ED) length of stay (LOS) and hospital admission.
This is a ...retrospective review of asthma encounters aged 2-17 years transported by EMS to a pediatric ED from 2012 to 2017. Our primary outcome was hospital admission based on prehospital protocol adherence defined as: (1) bronchodilator administration, (2) treatment of hypoxia with oxygen, or (3) administration of intramuscular (IM) epinephrine in encounters with high severity of distress. Multivariable logistic regression estimated the association between protocol non-adherence and hospital admission.
During the study period, 290 EMS encounters met inclusion criteria. Median age was 9 years (IQR 5-12), 63% were male, 40% had moderate to severe exacerbations, and 24% were admitted. Protocol non-adherence occurred in 32% of encounters with failure to administer bronchodilators in 27% and failure to administer IM epinephrine when indicated in 83%. Prehospital steroids were administered in 8% of encounters. After adjusting for covariates, protocol non-adherence was not statistically associated with likelihood of inpatient admission (OR 1.3; 95% CI: 0.6-2.6).
Among prehospital pediatric asthma encounters, EMS protocol non-adherence is common but not associated with a higher frequency of hospital admission. Hospital admission was associated with acute exacerbation severity suggesting further research is needed to develop a valid prehospital asthma severity assessment scoring tool.

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.
Sepsis is a life-threatening disease in children and is a leading cause of morbidity and mortality. Early prehospital recognition and management of children with sepsis may have significant effects ...on the timely resuscitation of this high-risk clinical condition. However, the care of acutely ill and injured children in the prehospital setting can be challenging. This study aims to understand barriers, facilitators, and attitudes regarding recognition and management of pediatric sepsis in the prehospital setting.
This was a qualitative study of EMS professionals participating in focus groups using a grounded theory-based design to gather information on recognition and management of septic children in the prehospital setting. Focus groups were held for EMS administrators and medical directors. Separate focus groups were held for field clinicians. Focus groups were conducted via video conference until saturation of ideas was reached. Using consensus methodology, transcripts were coded in an iterative process. Data were then organized into positive and negative factors based on the validated PRECEDE-PROCEED model for behavioral change.
Thirty-eight participants in six focus groups identified nine environmental factors, 21 negative factors, and 14 positive factors pertaining to recognition and management of pediatric sepsis. These findings were organized into the PRECEDE-PROCEED planning model. Pediatric sepsis guidelines were identified as positive factors when they did exist and negative factors when they were complicated or did not exist. Six interventions were identified by participants. These include raising awareness of pediatric sepsis, increasing pediatric education, receiving feedback on prehospital encounters, increasing pediatric exposure and skills training, and improving dispatch information.
This study fills a gap by examining barriers and facilitators to prehospital diagnosis and management of pediatric sepsis. Using the PRECEDE-PROCEED model, nine environmental factors, 21 negative factors, and 14 positive factors were identified. Participants identified six interventions that could create the foundation to improve prehospital pediatric sepsis care. Policy changes were suggested by the research team based on the results of this study. These interventions and policy changes provide a roadmap for improving care in this population and lay the groundwork for future research.
Prehospital Termination of Resuscitation (TOR) protocols for adults can reduce the number of futile transports of patients in cardiac arrest, yet similar protocols are not widely available for ...paediatric out-of-hospital cardiac arrest (POHCA). The objective of this study was to apply a set of criteria for paediatric TOR (pTOR) from the Maryland Institute for Emergency Medical Services Systems (MIEMSS) to a large national cohort and determine its association with return of spontaneous circulation (ROSC) after POHCA.
We identified patients ages 0–17 treated by Emergency Medical Services (EMS) with cardiac arrest in 2019 from the ESO dataset and and applied the applicable pTOR certeria for medical or traumatic arrests. We calculated predictive test characteristics for the outcome of prehospital ROSC, stratified by medical and traumatic cause of arrest.
We analyzed records for 1595 POHCA patients. Eighty-eight percent (n = 1395) were classified as medical. ROSC rates were 23% among medical POHCA and 27% among traumatic POHCA. The medical criteria correctly classified >99% (322/323) of patients who achieved ROSC as ineligible for TOR. The trauma criteria correctly classified 93% (50/54) of patients with ROSC as ineligible for TOR. Of the five misclassified patients, three were involved in drowning incidents.
The Maryland pTOR criteria identified eligible patients who did not achieve prehospital ROSC, while reliably excluding those who did achieve prehospital ROSC. As most misclassified patients were victims of drowning, we recommend considering the exclusion of drowning patients from future pTOR guidelines. Further studies are needed to evaluate the long-term survival and neurologic outcome of patients misclassified by pTOR criteria.
Study objective Cervical spine injuries in children are rare. However, immobilization and imaging for potential cervical spine injury after trauma are common and are associated with adverse effects. ...Risk factors for cervical spine injury have been developed to safely limit immobilization and radiography in adults, but not in children. The purpose of our study is to identify risk factors associated with cervical spine injury in children after blunt trauma. Methods We conducted a case-control study of children younger than 16 years, presenting after blunt trauma, and who received cervical spine radiographs at 17 hospitals in the Pediatric Emergency Care Applied Research Network (PECARN) between January 2000 and December 2004. Cases were children with cervical spine injury. We created 3 control groups of children free of cervical spine injury: (1) random controls, (2) age and mechanism of injury-matched controls, and (3) for cases receiving out-of-hospital emergency medical services (EMS), age-matched controls who also received EMS care. We abstracted data from 3 sources: PECARN hospital, referring hospital, and out-of-hospital patient records. We performed multiple logistic regression analyses to identify predictors of cervical spine injury and calculated the model's sensitivity and specificity. Results We reviewed 540 records of children with cervical spine injury and 1,060, 1,012, and 702 random, mechanism of injury, and EMS controls, respectively. In the analysis using random controls, we identified 8 factors associated with cervical spine injury: altered mental status, focal neurologic findings, neck pain, torticollis, substantial torso injury, conditions predisposing to cervical spine injury, diving, and high-risk motor vehicle crash. Having 1 or more factors was 98% (95% confidence interval 96% to 99%) sensitive and 26% (95% confidence interval 23% to 29%) specific for cervical spine injury. We identified similar risk factors in the other analyses. Conclusion We identified an 8-variable model for cervical spine injury in children after blunt trauma that warrants prospective refinement and validation.
Federal regulations allow exception from informed consent (EFIC) to study emergent conditions when obtaining prospective consent is not feasible. Little is known about public views on including ...children in EFIC studies. The Pediatric Dose Optimization for Seizures in EMS (PediDOSE) trial implements age-based, standardized midazolam dosing for pediatric seizures. The primary objective of this study was to determine public support for and concerns about the PediDOSE EFIC trial. The secondary objective was to assess how support for PediDOSE varied by demographics.
We conducted a mixed-methods study in 20 U.S. communities. Participants reviewed information about PediDOSE before completing an online survey. Descriptive data were generated. Univariable and multivariable logistic regression analysis identified factors associated with support for PediDOSE. Reviewers identified themes from free-text response data regarding participant concerns.
Of 2450 respondents, 79% were parents/guardians, and 20% had a child with previous seizures. A total of 96% of respondents supported PediDOSE being conducted, and 70% approved of children being enrolled without prior consent. Non-Hispanic Black respondents were less likely than non-Hispanic White respondents to support PediDOSE with an adjusted odds ratio (aOR) of 0.57 (95% CI 0.42-0.75). Health care providers were more likely to support PediDOSE, with strongest support among prehospital emergency medicine clinicians (aOR 5.82, 95% CI 3.19-10.62). Age, gender, parental status, and level of education were not associated with support of PediDOSE. Common concerns about PediDOSE included adverse effects, legal and ethical concerns about enrolling without consent, and potential racial bias.
In communities where this study will occur, most respondents supported PediDOSE being conducted with EFIC and most approved of children being enrolled without prior consent. Support was lowest among non-Hispanic Black respondents and highest among health care providers. Further research is needed to determine optimal ways to address the concerns of specific racial and ethnic groups when conducting EFIC trials.
Study objective We derive a prediction rule to identify children at very low risk for intra-abdominal injuries undergoing acute intervention and for whom computed tomography (CT) could be obviated. ...Methods We prospectively enrolled children with blunt torso trauma in 20 emergency departments. We used binary recursive partitioning to create a prediction rule to identify children at very low risk of intra-abdominal injuries undergoing acute intervention (therapeutic laparotomy, angiographic embolization, blood transfusion for abdominal hemorrhage, or intravenous fluid for ≥2 nights for pancreatic/gastrointestinal injuries). We considered only historical and physical examination variables with acceptable interrater reliability. Results We enrolled 12,044 children with a median age of 11.1 years (interquartile range 5.8, 15.1 years). Of the 761 (6.3%) children with intra-abdominal injuries, 203 (26.7%) received acute interventions. The prediction rule consisted of (in descending order of importance) no evidence of abdominal wall trauma or seat belt sign, Glasgow Coma Scale score greater than 13, no abdominal tenderness, no evidence of thoracic wall trauma, no complaints of abdominal pain, no decreased breath sounds, and no vomiting. The rule had a negative predictive value of 5,028 of 5,034 (99.9%; 95% confidence interval CI 99.7% to 100%), sensitivity of 197 of 203 (97%; 95% CI 94% to 99%), specificity of 5,028 of 11,841 (42.5%; 95% CI 41.6% to 43.4%), and negative likelihood ratio of 0.07 (95% CI 0.03 to 0.15). Conclusion A prediction rule consisting of 7 patient history and physical examination findings, and without laboratory or ultrasonographic information, identifies children with blunt torso trauma who are at very low risk for intra-abdominal injury undergoing acute intervention. These findings require external validation before implementation.
In 2017, the Health Resources and Services Administration's Maternal Child and Health Bureau's Emergency Medical Services for Children program implemented a performance measure for State Partnership ...grants to increase the percentage of EMS agencies within each state that have designated individuals who coordinate pediatric emergency care, also called a pediatric emergency care coordinator (PECC). The PECC Learning Collaborative (PECCLC) was established to identify best practices to achieve this goal. This study's objective is to report on the structure and outcomes of the PECCLC conducted among nine states.
This study used quantitative and qualitative methods to evaluate outcomes from the PECCLC. Participating state representatives engaged in a 6-month collaborative that included monthly learning sessions with subject matter experts and support staff and concluded with a two-day in-person meeting. Outcomes included reporting the number of PECCs recruited, identifying barriers and enablers to PECC recruitment, characterizing best practices to support PECCs, and identifying barriers and enablers to enhance and sustain the PECC role. Outcomes were captured by self-report from participating state representatives and longitudinal qualitative interviews conducted with representative PECCs at 6 and 18 months after conclusion of the PECCLC.
During the 6-month collaborative, states recruited 341 PECCs (92% of goal). Follow up at 5 months post-collaborative revealed an additional recruitment of 184 for a total of 525 PECCs (142% of the goal). Feedback from state representatives and PECCs revealed the following barriers: competition from other EMS responsibilities, budgetary constraints, lack of incentive for agencies to create the position, and lack of requirement for establishing the role. Enablers identified included having an EMS agency recognition program that includes the PECC role, train-the-trainer programs, and inclusion of the PECC role in agency licensure requirements. Longitudinal interviews with PECCs identified that the most common activity associated with their role was pediatric-specific education and the most important need for PECC success was agency-level support.
Over the 6-month Learning Collaborative, nine states were successful in recruiting a substantial number of PECCs. Financial and time constraints were significant barriers to statewide PECC recruitment, yet these can be potentially addressed by EMS agency recognition programs.
Introduction: Prehospital intravenous (IV) access in children may be difficult and time-consuming. Emergency Medical Service (EMS) protocols often dictate IV placement; however, some IV catheters may ...not be needed. The scene and transport time associated with attempting IV access in children is unknown. The objective of this study is to examine differences in scene and transport times associated with prehospital IV catheter attempt and utilization patterns of these catheters during pediatric prehospital encounters. Methods: Three non-blinded investigators abstracted EMS and hospital records of children 0-18 years of age transported by EMS to a pediatric emergency department (ED). We compared patients in which prehospital IV access was attempted to those with no documented attempt. Our primary outcome was scene time. Secondary outcomes include utilization of the IV catheter in the prehospital and ED settings and a determination of whether the catheter was indicated based on a priori established criteria (prehospital IV medication administration, hypotension, GCS < 13, and ICU admission). Results: We reviewed 1,138 records, 545 meeting inclusion criteria. IV catheter placement was attempted in 27% (n = 149) with success in 77% (n = 111). There was no difference in the presence of hypotension or median GCS between groups. Mean scene time (12.5 vs. 11.8 minutes) and transport time (16.9 vs. 14.6 minutes) were similar. Prehospital IV medications were given in 38.7% (43/111). One patient received a prehospital IV medication with no alternative route of administration. Among patients with a prehospital IV attempt, 31% (46/149) received IV medications in the ED and 23% (34/396) received IV fluids in the ED. Mean time to use of the IV in the ED was 70 minutes after arrival. Patients with prehospital IV attempt were more likely to receive IV medication within 30 minutes of ED arrival (39.1% vs. 19.0%, p = 0.04). Overall, 34.2% of IV attempts were indicated. Conclusions: Prehospital IV catheter placement in children is not associated with an increase in scene or transport time. Prehospital IV catheters were used in approximately one-third of patients. Further study is needed to determine which children may benefit most from IV access in the prehospital setting.
