Emergency Medical Services Utilization Is Associated With Community Deprivation in Children

Comparison of Neighborhood Disadvantage Indices on Emergency Medical Services Interventions and Outcomes for Pediatric Out-of-Hospital Emergencies

OBJECTIVE

Measures of neighborhood disadvantage demonstrate correlations to health outcomes in children. We compared differing indices of neighborhood disadvantage with emergency medical services (EMS) interventions in children.

METHODS

We performed a retrospective study of EMS encounters for children (<18 years) from approximately 2000 US EMS agencies between 2021 and 2022. Our exposures were the Child Opportunity Index (COI; v2.0), 2021 Area Deprivation Index (ADI), and 2018 Social Vulnerability Index (SVI). We evaluated the agreement in how children were classified with each index using the intraclass correlation coefficient. We used logistic regression to evaluate the association of each index with transport status, presence of cardiac arrest, and condition-specific interventions and assessments.

RESULTS

We included 738,892 encounters. The correlation between the indices indicated good agreement (intraclass correlation coefficient=0.75). There was overlap in relationships between the COI, ADI, and SVI for each of the study outcomes, both when visualized as a splined predictor and when using representative odds ratios (OR) comparing the third quartile of each index to the lower quartile (most disadvantaged). For example, the OR of non-transport was 1.12 (95% confidence interval [CI]: 1.10-1.14) for COI, 1.18 (95% CI: 1.16-1.20) for ADI, and 1.22 (95% CI: 1.20-1.23) for SVI.

CONCLUSION

The COI, ADI, and SVI had good correlation and demonstrated similar effect size estimates for a variety of clinical outcomes. While investigators should consider potential causal pathways for outcomes when selecting an index for neighborhood disadvantage, the relative strength of association between each index and all outcomes was similar.

Ambulance service recognition of health inequalities and activities for reduction: An evidence and gap map of the published literature

Background

Emergency medical services (EMS) are often patients' first point of contact for urgent and emergency care needs. Patients are triaged over the phone and may receive an ambulance response, with potential conveyance to the hospital. A recent scoping review suggested disparities in EMS patient care in the United States. However, it is unknown how health inequalities impact EMS care in other developed countries and how inequalities are being addressed.

Objectives

This rapid evidence map of published literature aims to map known health inequalities in EMS patients and describe interventions reducing health inequalities in EMS patient care.

Methods

The search strategy consisted of EMS synonyms and health inequality synonyms. The MEDLINE/PubMed database was searched from 1 January 2010 to 26 July 2022. Studies were included if they described empirical research exploring health inequalities within ambulance service patient care. Studies were mapped on to the EMS care interventions framework and Core20PLUS5 framework. Studies evaluating interventions were synthesised using the United Kingdom Allied Health Professions Public Health Strategic Framework.

Results

The search strategy yielded 771 articles, excluding duplicates, with two more studies added from hand searches. One hundred studies met the inclusion criteria after full-text review. Inequalities in EMS patient care were predominantly situated in assessment, treatment and conveyance, although triage and response performance were also represented. Studies mostly explored EMS health inequalities within ethnic minority populations, populations with protected characteristics and the core issue of social deprivation. Studies evaluating interventions reducing health inequalities (n = 5) were from outside the United Kingdom and focused on older patients, ethnic minorities and those with limited English proficiency. Interventions included community paramedics, awareness campaigns, dedicated language lines and changes to EMS protocols.

Conclusions

Further UK-based research exploring health inequalities of EMS patients would support ambulance service policy and intervention development to reduce health inequality in urgent and emergency care delivery.

Evaluation of the implementation of evidence-based pediatric asthma exacerbation treatments in a regional consortium of emergency medical Services Agencies

OBJECTIVE

Asthma exacerbations are a frequent reason for pediatric emergency medical services (EMS) encounters. The objective of this study was to examine the implementation of evidence-based treatments for pediatric asthma in a regional consortium of EMS agencies.

METHODS

This retrospective study applied the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) implementation framework to data from an EMS agency consortium in the Cincinnati, Ohio region. The study analyzed one year before an oral systemic corticosteroid (OCS) option was added to the agencies' protocol, and five years after the protocol change. We constructed logistic regression models for the primary outcome of Reach, defined as the proportion of pediatric asthma patients who received a systemic corticosteroid. We modeled Maintenance (Reach measured monthly over time) using time series models.

RESULTS

A total of 713 patients were included, 133 pre- and 580 post-protocol change. In terms of Reach, 3% (n = 4) of eligible patients received a systemic corticosteroid pre-OCS versus 20% (n = 116) post-OCS. Multivariable modeling of Reach revealed the study period, EMS transport time, months since implementation of OCS, and number of bronchodilators administered by EMS as significant covariates for the administration of a systemic corticosteroid. For Maintenance, it took approximately two years to reach maximal administration of systemic corticosteroids.

CONCLUSIONS

Indicators of asthma severity and time since the protocol change were significantly associated with EMS administration of systemic corticosteroids to pediatric asthma patients. The two-year time for maximal Reach suggests further work is required to understand how to best implement evidence-based pediatric asthma treatments in EMS.

Measures of Patient Acuity Among Children Encountered by Emergency Medical Services by the Child Opportunity Index

Background: Children have differing utilization of emergency medical services (EMS) by socioeconomic status. We evaluated differences in prehospital care among children by the Child Opportunity Index (COI), the agreement between a child's COI at the scene and at home, and in-hospital outcomes for children by COI. Methods: We performed a retrospective study of pediatric (<18 years) scene encounters from approximately 2,000 United States EMS agencies from the 2021-2022 ESO Data Collaborative. We evaluated socioeconomic status using the multi-dimensional COI v2.0 at the scene. We described EMS interventions and in-hospital outcomes by COI categories using ordinal regression. We evaluated the agreement between the home and scene COI. Results: Data were available for 99.8% of pediatric scene runs, with 936,940 included EMS responses. Children from lower COI areas more frequently had a response occurring at home (62.9% in Very Low COI areas; 47.1% in Very High COI areas). Children from higher COI areas were more frequently not transported to the hospital (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.86-0.87). Children in lower COI areas had lower use of physical (OR 1.23, 95% CI 1.13-1.33) and chemical (OR 1.41, 95% CI 1.29-1.55) restraints for behavioral health problems. Among injured children with elevated pain scores (≥7), analgesia was provided more frequently to children in higher COI areas (OR 1.73, 95% CI 1.65-1.81). The proportion of children in cardiac arrest was lowest from higher COI areas. Among 107,114 encounters with in-hospital data, the odds of hospitalization was higher among children from higher COI areas (OR 1.14, 95% CI 1.11-1.18) and was lower for in-hospital mortality (OR 0.75, 95% CI 0.65-0.85). Home and scene COI had a strong agreement (Kendall's W = 0.81). Conclusion: Patterns of EMS utilization among children with prehospital emergencies differ by COI. Some measures, such as for in-hospital mortality, occurred more frequently among children transported from Very Low COI areas, whereas others, such as admission, occurred more frequently among children from Very High COI areas. These findings have implications in EMS planning and in alternative out-of-hospital care models, including in regional placement of ambulance stations.

Using Natural Language Processing to Examine Social Determinants of Health in Prehospital Pediatric Encounters and Associations with EMS Transport Decisions

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

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.

Time to change the reference ranges of children's physiological observations in emergency care? A prospective study

AIM

High heart and respiratory rates are key indicators in many published guidelines to identify and treat serious bacterial infection and sepsis in children, but the credibility of evidence underpinning what is considered abnormal is questionable. This study established the distribution of heart and respiratory rates of children using a large data set to inform debate on what the 'normal' range of these should look like. The primary aim was to compare the distribution of heart and respiratory rates measured in children recruited from non-tertiary emergency care settings with those published by Advanced Paediatric Life Support (APLS). The secondary aim was to compare the distribution of this study's data set to other national guidance on what constitutes a severe (high-risk) measurement and previously published data sets.

METHOD

Prospective study using anonymised patient data, extracted from electronic patient records of children and young people 0-16 years, recruited from three Emergency Departments and one Urgent Care Centre in Northwest England, UK.

RESULTS

Heart and respiratory rates, including the reporting of values at certain centiles and comparisons of averages. Distribution of heart and respiratory rate were consistently higher than those used by the APLS guidance, resulting in a large proportion exceeding the 'severe' cut-offs proposed. This varied greatly by age.

CONCLUSIONS

This study's data set suggests normal heart rate ranges proposed by the APLS and others is too low and therefore 'abnormal' measurements encompass too large a proportion. The respiratory rate of this data set was more consistent with the guidelines and other published data sets.

Length of stay in the emergency department and its associated factors among pediatric patients attending Wolaita Sodo University Teaching and Referral Hospital, Southern, Ethiopia

BACKGROUND

Globally, there is an increase in the need for emergency department visits, which is exceptionally high in pediatric patients, resulting in longer lengths of stay, which is a global challenge and a hospital bottleneck that increases the risk of patient morbidity and mortality while also lowering satisfaction.

OBJECTIVE

This study aimed to assess the length of stay and associated factors in the pediatric emergency department at Wolaita Sodo University Hospital in 2021.

METHODS

An institution-based cross-sectional investigation was undertaken from March 15 to May 15, 2021. The 422 study participants were chosen using a systematic sampling procedure. The data were collected using semi-structured interviewer-administered questionnaires and chart reviews. Epi Data version 4.6 was used to enter the data, while SPSS version 26 was used to analyze it. With a 95% confidence interval, descriptive statistics were used to describe the prevalence, pediatrics, and emergency department duration of stay. The factors related to the length of stay were identified using bivariable and multivariable logistic regression analysis. On the AOR, a significant level was proclaimed when the p-value was less than 0.05, and the confidence interval was less than 95%.

RESULTS

The proportion of prolonged pediatric emergency department length of stay was 79.70% (95% CI; 75.7, 83.6). Nighttime arrival [AOR = 3.19, 95% CI (1.14, 8.98)], weekend arrival [AOR = 4.25, 95% CI (1.49, 5.35)], not receiving ordered medication in the hospital [AOR = 2.05, 95% CI (1.04, 4.03)], orange triage category [AOR = 4.01, 95% CI (1.60, 10.05)], and duration of pain 13-24 h [AOR = 0.29, 95% CI (0.89,0.98)], were significantly associated with length of stay.

CONCLUSION

The percentage of children who stayed in the pediatric emergency department for an extended period was high. Policymakers should implement evidence-based care, maximize existing resources, provide equal access to care and high-quality care, and make pediatric emergency departments more accessible and operationally efficient.

Paediatric frequent use of emergency medical services: a systematic review

BACKGROUND

Frequent use of emergency medical services (EMS) is recognised to be a global phenomenon, although paediatric frequent use is poorly understood. This systematic review aimed to understand how paediatric frequent use of EMS is currently defined, identify factors associated with paediatric frequent use of EMS and determine effectiveness of interventions for paediatric patients who frequently use EMS.

METHODS

Four electronic databases (Medline, CINAHL, Web of Science and PsycINFO) were searched to September 2022 for primary, peer-reviewed research studies published in English from January 2000. Studies were included that examined frequent use (>1 contact during study period) of EMS or other services with arrival via EMS. Paediatric patients were defined as <18 years of age or otherwise defined by study authors as paediatric/adolescent/children. Data were extracted using a structured proforma, and quality was assessed using the Standard Quality Assessment Criteria for Quantitative Studies but did not influence inclusion decisions. Data were presented using narrative synthesis.

RESULTS

The search resulted in 4172 unique references, with 12 papers included in the review from 7 countries. Four were EMS studies, and eight Emergency Department with arrival via EMS. All studies used retrospective designs, with no interventional studies identified. Paediatric frequent EMS users were more likely to use services for medical reasons rather than trauma, including respiratory complaints, mental health and seizures, but data on gender and ethnicity were inconclusive and silent on socioeconomic status. There was no consistency in definitions of either a paediatric patient or of frequent use.

CONCLUSION

The broad range of reasons for frequent use suggests that a single intervention is unlikely to be effective at addressing the causes of frequent use. There is a need for further research to better identify the underlying reasons for frequent EMS use among paediatric patients and to develop interventions in this population.

An Assessment of a Socioeconomic Risk Screening Tool for Telemedicine Encounters in Pediatric Primary Care: A Pilot Study

Socioeconomic adversity negatively affects child health. Telemedicine use in pediatrics is rapidly expanding. We piloted a socioeconomic risk screening tool within telemedicine visits. Using chart review, our primary aim was to assess the rates of screen completion, risk identification, and referral generation during telemedicine visits. Our secondary aim was to assess family satisfaction and barriers to connecting with referrals/interventions through follow-up telephone interviews. This study included 179 telemedicine encounters. The screening tool was completed in 63% of encounters and was positive in 5% of encounters. Of those who identified socioeconomic risks, 90% received a referral/intervention (social work consultation, food pantry, etc.). During follow-up calls, families expressed satisfaction with telemedicine, though 31% described difficulty connecting with the recommended services. High rates of socioeconomic risk screening resulting in interventions are achievable during telemedicine visits. Further work is needed to identify optimal socioeconomic risk screening questions and opportunities, and to ensure successful interventions.

The Utility of the Brokamp Area Deprivation Index as a Prescreen for Social Risk in Primary Care

OBJECTIVES

To assess the relationship between an Area Deprivation Index (ADI) and a Social Determinant of Health (SDoH) measure within a diverse sample. A prescreening tool based on routinely collected information could reduce clinical burden by identifying patients impacted by SDoH for comprehensive assessment.

STUDY DESIGN

In total, 499 consented pediatric patient-families who spoke English, Spanish, or Arabic and had a child ≤12 years receiving primary care at a large academic institution were enrolled. Participants completed the Health Leads Social Needs (HLSN) survey. Residential address was extracted from the electronic health record to calculate Brokamp ADI at the census-tract level. The main outcome was the correlations between the total HLSN score and Brokamp ADI, overall and in each language subgroup. ADI distributions were also compared between participants with/without need for each of the 8 HLSN survey SDoH domains, using 2-sample t-tests and Pearson χ² tests.

RESULTS

In total, 54.9% of participants were English-speaking, 30.9% were Spanish-speaking, and 14.2% were Arabic-speaking. Spearman correlations between Brokamp ADI and total HLSN score were overall (r_s = 0.15; P = .001), English (r_s = 0.12; P = .04), Spanish (r_s = 0.03; P = .7), and Arabic (r_s = 0.24; P = .04). SDoH domain analyses found significant ADI differences between those with/without need in housing instability, childcare, transportation, and health literacy.

CONCLUSIONS

There were small but statistically significant associations between the Brokamp ADI and total HLSN score and SDoH domains of housing instability, childcare, transportation, and health literacy. These findings support testing the Brokamp ADI as a prescreening tool to help identify patients with social needs in an outpatient clinical setting.

The relationship between emergency medical services use and social service needs in a pediatric emergency department population

BACKGROUND

Emergency Medical Services (EMS) use for children is correlated with areas of resource deprivation as well as child maltreatment. Households using EMS may have more social needs and be willing to accept services.

OBJECTIVE

To compare social service needs and willingness to accept services in families arriving to a pediatric emergency department (ED) via EMS vs non-EMS, before and during COVID-19.

PARTICIPANTS AND SETTING

Caregivers of children 0-5 years old in a quaternary pediatric ED, with a 1:1 ratio of EMS vs non-EMS arrivals.

METHODS

Participants completed a survey of demographics, social service needs, and willingness to accept services, before and during COVID-19.

RESULTS

Of 220 participants, 84 were enrolled before COVID-19. The EMS group reported less full-time employment (34.6% vs 51.8%, p < 0.05) and more social service needs (2.47 vs 1.76 needs, p < 0.05). Mean score for willingness to accept a service provider in the home was 3.62 for EMS and 3.19 for non-EMS (p = 0.09). Mean score for accepting a phone referral was 3.84 for EMS and 3.40 for non-EMS (p = 0.07). COVID-19 impacted needs for both groups (20.9% EMS vs 30.3% non-EMS). For all subjects presenting to the ED, COVID-19 was associated with decreased food insecurity (28.6% vs 15.4%) and children with a chronic medical condition (31.0% vs 12.5%).

CONCLUSIONS

The EMS group had more social service needs. There was no difference in social services acceptance. COVID-19 affected both groups' needs. Future interventions may use EMS systems to mitigate social service needs which may be risk factors for child abuse.

Voter Participation is Associated with Child Health Outcomes at the Population Level

Civic engagement, including voting, has been linked to health outcomes for adults. Here, we found that census tract-level voter participation rates are significantly associated with pediatric inpatient bed-day rates even after adjustment for socioeconomic deprivation. Such links suggest that promotion of voting participation could be warranted in healthcare settings.

Seven practices for pursuing equity through learning health systems: Notes from the field

INTRODUCTION

Despite learning health systems' focus on improvement in health outcomes, inequities in outcomes remain deep and persistent. To achieve and sustain health equity, it is critical that learning health systems (LHS) adapt and function in ways that directly prioritize equity.

METHODS

We present guidance, including seven core practices, borne from theory, evidence, and experience, for actors within LHS pursuing equity.

RESULTS

We provide a foundational definition of equity. We then offer seven core practices for how LHS may effectively pursue equity in health: establish principle, measure for equity, lead from lived experience, co-produce, redistribute power, practice a growth mindset, and engage beyond the healthcare system. We include three use cases that illustrate ways in which we have begun to center equity in the work of our own LHS.

CONCLUSION

The achievement of equity requires real transformation at individual, institutional, and structural levels and requires sustained and persistent effort.

Neighborhood socioeconomic deprivation is associated with worse patient and graft survival following pediatric liver transplantation

Long-term outcomes remain suboptimal following pediatric liver transplantation; only one third of children have normal biochemical liver function without immunosuppressant comorbidities 10 years posttransplant. We examined the association between an index of neighborhood socioeconomic deprivation with graft and patient survival using the Scientific Registry of Transplant Recipients. We included children <19 years who underwent liver transplantation between January 1, 2008 to December 31, 2013 (n = 2868). Primary exposure was a neighborhood socioeconomic deprivation index-linked via patient home ZIP code-with a range of 0-1 (values nearing 1 indicate neighborhoods with greater socioeconomic deprivation). Primary outcome measures were graft failure and death, censored at 10 years posttransplant. We modeled survival using Cox proportional hazards. In univariable analysis, each 0.1 increase in the deprivation index was associated with a 14.3% (95% confidence interval [CI]): 3.8%-25.8%) increased hazard of graft failure and a 12.5% (95% CI: 2.5%-23.6%) increased hazard of death. In multivariable analysis adjusted for race, each 0.1 increase in the deprivation index was associated with a 11.5% (95% CI: 1.6%-23.9%) increased hazard of graft failure and a 9.6% (95% CI: -0.04% to 20.7%) increased hazard of death. Children from high deprivation neighborhoods have diminished graft and patient survival following liver transplantation. Greater attention to neighborhood context may result in improved outcomes for children following liver transplantation.
