Factors associated with EMS transport decisions for pediatric patients after motor vehicle collisions

Pediatric Outcomes of Emergency Medical Services Non-Transport Before and During the COVID-19 Pandemic

Introduction

Pediatric patients account for 6-10% of emergency medical services (EMS) activations in the United States. Approximately 30% of these children are not transported to an emergency department (ED). Adult data in the literature reports higher hospitalization and complications following non-transport. Few studies discuss epidemiology and characteristics of pediatric non-transport; however, data on outcome is limited. Our primary aim was to determine outcomes of non-transported children within our urban EMS system before and during the COVID-19 pandemic. Our secondary objective was to explore reasons for non-transport.

Methods

This was a prospective, descriptive pilot study. We compared EMS data for September 2019 (pre-COVID-19) to September 2020 (pandemic). Included were children aged 0-17 years who activated EMS and did not receive transport to the primary hospital for the EMS capture area. We defined outcomes as repeat EMS activation, ED visits, and hospital admissions, all within 72 hours. Data was obtained via electronic capture. We used descriptive statistics to analyze our data, chi square for categorical data, stepwise logistic regression, and univariate logistic regression to test for association of covariates with non-transport.

Results

There were 1,089 pediatric EMS activations in September 2019 and 780 in September 2020. Non-transport occurred in 633 (58%) in September 2019 and 412 (53%) in September 2020. Emergency medical services was reactivated within 72 hours in the following: 9/633 (1.4%) in 2019; and 5/412 (1.2%) in 2020 (P = 0.77). Visits to the ED occurred in 57/633 (9%) in 2019 and 42/412 (10%) in 2020 (P = 0.53). Hospital admissions occurred in 10/633 (1.5%) in 2019 and 4/412 (0.97%) in 2020 (P = 0.19). One non-transported patient was admitted to the intensive care unit in September 2020 (<1%) and survived. Hispanic ethnicity, age >12 years, and fever were associated with repeat EMS activation. The most common reason for non-transport in both study periods was that the parent felt an ambulance was not necessary (47%).

Conclusion

In our system, non-transport of pediatric patients occurred in >50% of EMS activations with no significant adverse outcome. Age >12 years, fever, and Hispanic ethnicity were more common in repeated EMS activations. The most common reason for non-transport was parents feeling it was not necessary. Future studies are needed to develop reliable EMS guidelines for pediatric non-transport.

The Child Opportunity Index and Pediatric Emergency Medical Services Utilization

Background: The delivery of emergency medical services (EMS) is a resource-intensive process, and prior studies suggest that EMS utilization in children may vary by socioeconomic status. The Child Opportunity Index (COI) provides a multidimensional measure of neighborhood-level resources and conditions that affect the health of children. We evaluated EMS utilization and measures of acuity among children by COI.Methods: We performed a cross-sectional study using encounters for patients less than 18 years of age from 10,067 EMS agencies in 47 US states and territories contributing to the National Emergency Medical Services Information System 2019 dataset. We compared patient demographics, EMS encounter characteristics, and care provided to children stratified by ZIP code using the COI 2.0.Results: We included 1,293,038 EMS encounters (median age 10 years, IQR 3-15 years). The distributions of encounters in the five tiers of COI were 30.6%, 20.1%, 18.0%, 16.3% and 15.1%, (from Very Low to Very High, respectively). The distribution of diagnoses between groups was similar. Most measures of EMS acuity/resource use were similar between groups, including non-transport status, cardiac arrest, vital sign abnormalities, and EMS-administered procedures and medications. Among children with respiratory-related encounters, children in the Very Low group had a greater need for nebulized medications (26.4% vs 18.3% in Very High COI children). Among children with trauma, a lower proportion in the Very Low group were given analgesia (4.0% vs 7.4% in the Very High group), though pain scores were similar in all groups.Conclusion: Pediatric EMS encounters from lower COI neighborhoods occur more frequently relative to encounters from higher COI neighborhoods. Despite these differences, children from lower COI strata generally have similar encounter characteristics to those in other COI strata, suggestive of a greater number of true out-of-hospital emergencies among children from these areas. Notable differences in care included use of respiratory medication to children with respiratory diagnoses, and administration of pain medication to children with trauma.

Prehospital Emergency Provider's Knowledge of and Comfort With Pediatric and Special Needs Cases: A Cross-Sectional Study in Los Angeles County

The current study assesses the relationship between continuing education (CE) with a focus on pediatrics and children with special heath care needs and how CE influences the knowledge and comfort levels of prehospital providers who treat these cases. Data are survey responses provided by paramedic and emergency medical technician (EMT) level providers (N = 575) in Los Angeles County. Regression models assessed the relationship between pediatric-focused continuing education and EMTs' knowledge of and comfort with pediatric cases, adjusting for relevant covariates. EMTs' participation in continuing education focusing on pediatrics and special health care needs was significantly associated with an increase in perceived comfort and knowledge. Among EMTs who did not receive continuing education focused on either pediatrics or special health care needs, the most frequently reported barrier to education was a perceived lack of availability. The impact of continuing education on perceived comfort and knowledge was more pronounced than the effect of prior experience, especially considering the limited prevalence of provider exposure to pediatric and childhood special health care needs cases compared to adult cases. Expanding educational opportunities is a promising approach to increasing the comfort and knowledge of EMTs who transport and care for pediatric cases.
