Emergency Department Utilization Among Assault-Injured Youth: Implications for Youth Violence Screening

"I Have More Friends That Died Than Fingers and Toes": Service Utilization Needs and Preferences for Violence and Substance Use Prevention Among Young Black Boys and Men

Young Black men (YBM) disproportionately face the most severe forms and consequences of youth violence (YV) and substance use disorders, but are less likely to access and be retained in services for these high-risk behaviors. Investigating service uptake disparities and the role of barrier-reducing intervention delivery models is essential; so is understanding the service needs and preferences of YBM. This study explores the experiences of violence-involved and substance-disordered YBM and service providers working with them from racially and economically diverse communities, focusing on their service needs and preferences. Additionally, we examine the potential benefits and drawbacks of digital health interventions in addressing crucial structural barriers to service access and promoting equity for Black boys in high-violence environments. Individual interviews were conducted with 16 YBM (selected from a larger pool of 300 participants from a pilot study) and 7 service providers (four females, three males). Data analysis utilized an Interpretive Description (ID) approach guided by the Phenomenological Variant of Ecological Systems Theory (PVEST). Four themes emerged: (1) Revolving Doors and Histories of Violence; (2) Benefits of Violence: "You Do Something to Me, I Do Something to You"; (3) Positive and Negative Perceptions of Violence and Substance Use Prevention Programs; and (4) Need for Equity-Focused and Barrier-Mitigating Digital Health Interventions. Our findings identified avoidance mechanisms utilized by YBM at both individual and community levels and highlighted perceptions of existing community-based programs and digital interventions as crucial tools for mitigating barriers to care. This study also confirms the prevalence of critical service gaps and program uptake issues, even in cities with abundant programs. Thus emphasizing the need for equity-focused interventions co-designed with and for YBM in high-violence and substance use contexts.

Emergency department utilization by youth before and after firearm injury

BACKGROUND

Emergency department (ED) visits may serve as opportunities for firearm injury prevention and intervention efforts. Our objective was to determine ED utilization by youth before and after firearm injury.

METHODS

We performed a retrospective cohort study of ED encounters by youth (0-18 years old) with firearm injury from eight states using the 2019 State ED and Inpatient Databases. Our primary outcome was an ED encounter (1) 90 days before or (2) 90 days after index injury. We used generalized estimating equations, accounting for hospital clustering, to determine associations between ED utilization and ED type (pediatric vs. general), youth age, sex, race and ethnicity, urbanicity, and insurance status.

RESULTS

We identified 1035 ED encounters for firearm injury (median [IQR] age 17 (15-18) years, 85.3% male, 63.3% non-Hispanic Black, 68.6% publicly insured, 90.5% living in a metropolitan area, 52.8% general ED). In the 90 days before an index injury, 12.8% of youth had an ED encounter; of these, 68.2% occurred in general EDs, and 18.2% were for trauma. In the 90 days after an index injury, 22.1% of youth had an ED encounter; of these, 50.0% occurred in general EDs, and 22.6% were for trauma. We found no significant association between ED type and ED utilization patterns. Few youths changed ED type across longitudinal encounters.

CONCLUSIONS

Youth have high rates of ED utilization before and after firearm injury. Half of firearm-injured youth receive their emergency care exclusively in general EDs. Implementing firearm injury prevention and intervention efforts in all ED settings is critical.

Emergency Department Usage Patterns Among Pediatric Victims of Gun Violence and Physical Assault

OBJECTIVE

Violent injuries are a common reason for pediatric emergency department (ED) visits, with gun violence being the leading cause of violent death among children. The objective of this study was to assess for patterns of pediatric ED usage that are associated with future ED visits for violent injuries.

METHODS

This case-control study included youths aged 6 to 19 years who presented to a pediatric ED over a 3-year period due to a physical assault (PA) or their first known gunshot wound (GSW). We compared them with age-, race-, and sex-matched youths presenting for nonviolent medical complaints. All previous ED visits were coded as (1) injuries due to a previous PA, (2) mental/behavioral health visits, (3) sexual/reproductive health visits, (4) sexual assault, or (5) concerns for child abuse. We used multivariate logistic regression to identify patterns of previous ED usage associated with future ED visits for injuries related to PA and/or GSW.

RESULTS

The PA and GSW groups used the ED for previous PAs, mental/behavioral health, sexual/reproductive health, sexual assault, and/or child abuse concerns on average 4 to 8 times as often as the control group. Previous ED visits for mental/behavioral health (odds ratio [OR] 5), sexual/reproductive health (OR 3), sexual assault (OR 9), and prior PA (OR 8) were predictive of a future ED visit for PA. Male sex (OR 6) and previous ED visits for PA (OR 5) were predictive of a future ED visit for GSW. Two percent of the PA group and 9% of the GSW group returned to the ED with a subsequent GSW in the following 16 to 40 months.

CONCLUSIONS

Emergency department visits due to interpersonal violence, mental/behavioral health, sexual/reproductive health, and sexual assault are associated with recurrent ED visits for violent injuries. Awareness of patterns of ED usage may aid in identifying patients at high risk for violence and increase opportunities for preventative interventions.

Feasibility of linking violent death decedents to prior-month emergency department visits in North Carolina, 2019-2020

OBJECTIVE

Linking data between violent death decedents and other sources can provide valuable insight, highlighting opportunities for prevention of violent injury. This study investigated the feasibility of linking North Carolina Violent Death Reporting System (NC-VDRS) records with North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT) emergency department (ED) visit data to identify prior-month ED visits among this population.

METHODS

NC-VDRS death records from 2019 through 2020 were linked to NC DETECT ED visit data from December 2018 through 2020 using a probabilistic linkage approach. Linkage variables included date of birth, age, sex, zip code and county of residence, date of event (death/ED visit) and mechanism of injury. Potential linkable ED visits were filtered to those occurring in the month prior to death and manually reviewed for validity. Linked records were compared with the NC-VDRS study population to assess linkage performance and generalisability.

RESULTS

Among the 4768 violent deaths identified, we linked 1340 NC-VDRS records to at least one ED visit in the month prior to death. A higher proportion of decedents dying in medical facilities (ED/outpatient, hospital inpatient, hospice or nursing/long-term care facility) linked to a prior-month visit (80%) relative to those dying in other locations (12%). When stratified by place of death, linked decedents demographically resembled the overall NC-VDRS study population.

CONCLUSIONS

Though resource intensive, an NC-VDRS-to-NC DETECT linkage was successful in identifying prior-month ED visits among violent death decedents. This linkage should be leveraged to further analyse ED utilisation prior to violent death, expanding the knowledge base surrounding prevention opportunities for violent injuries.

Adolescent Violent Delinquency Associated With Increased Emergency Department Usage in Young Adulthood

Limited research has examined the extent to which adolescent delinquency predicts healthcare usage in young adulthood, including emergency department (ED) visits. This study used data from 3,310 adolescents (52.05% female; mean age at Wave I = 16.04 years) from the sibling subsample of the National Longitudinal Study of Adolescent to Adult Health (Add Health). We examined whether adolescent delinquency at Wave I predicted ED visits at Wave III using sibling fixed effects models to adjust estimates for within-family unobserved heterogeneity. Increased violent, but not nonviolent, delinquency predicted a higher number of ED visits in early adulthood in the sibling fixed effects models. To our knowledge, this is the first study to examine the relationship between delinquency and ED usage using a sibling fixed effects design. Findings demonstrate that violent adolescent delinquency may increase healthcare usage and suggest the potential role of healthcare providers in improving outcomes for delinquent youth.

Emergency department visit patterns in the recently discharged, violently injured patient: Retrospective cohort review

BACKGROUND

Analysis of the costs associated with emergency department (ED) visits after discharge for violent injury could highlight subgroups for the development of cost-effective interventions to support healing and prevent treatment failures in violently injured patients.

METHODS

A retrospective cohort review was conducted of all patients with return ED visits within 90 days of discharge after treatment for a violent injury occurring between July 1, 2016, and June 30, 2018. Hospital costs were calculated for each incidence and analyzed against demographic and injury type variables to identify trends.

RESULTS

218 return ED visits were identified. Hospital costs showed a high frequency of low-cost visits. For more complex visits, distinct cost patterns were observed for Black and LatinX males compared to White males as a function of age.

CONCLUSIONS

Analysis of hospital cost per visit identified trends among different subgroups. Underlying etiologies presumably vary between groups, but hypothesis-driven further investigation and needs assessment is required. Understanding the driving forces behind these cost trends may aid in developing effective interventions.

Partners in prevention: the role of health systems in the prevention of youth violence in post-conflict Northern Ireland

Interpersonal violence is a wicked and complex issue with youth disproportionately affected. Its effects are multifaceted, placing an additional burden across systems. Despite this, there continues to be an exclusive focus on police recorded crime data in the context of post-conflict Northern Ireland. Given the enduring issue around police legitimacy, it is likely that police-related crime data are limited in its capacity to estimate incidences and trends of youth violence. Leveraging insights from other sources of data can add significant value in the prevention of youth violence. For example, there is significant utility in the use of health-related data in the prevention of higher-harm violence; however, in the context of Northern Ireland this has been under-evaluated. This retrospective cohort study sought to illustrate what could be gleaned using a novel approach to Emergency Department (ED) data. Routinely collected data captured from youth aged 12–25 attending an ED trauma centre for violence-related injuries between August 2020 and August 2021 were collated, coded and analysed. We found that young men were most likely to present to ED with violence-related injuries; incidences were temporally clustered across several months of the year (i.e. Summer); and younger aged youth were at greater risk of violence-related injuries during the afternoon and early evening. These findings illustrate the utility of health data for violence prevention and the potential for integrating administrative datasets in the design of prevention policy. Limitations and implications for practice are discussed.

Profiles After Acute Traumatic Injury: The Non-battle Injury Impact on Readiness at a Single Military Treatment Facility

INTRODUCTION

Physical profiling is critical to the individual medical readiness of all military service members. This classification system provides detailed information about an individual's functional abilities. Profile information is used in determining whether a service member is medically deployable or non-deployable. Limited research has been conducted on the impact of acute traumatic injuries on duty status and profiles in the non-deployed setting. The purpose of this study was to characterize injured service members presenting to a CONUS MTF emergency department whose acute traumatic injury resulted in a profile.

MATERIALS AND METHODS

A retrospective review of patients who presented to the Dwight D. Eisenhower Army Medical Center emergency department with traumatic injuries from January 1, 2019, to December 31, 2019, was performed. Patients were identified by searching electronic encounter records for trauma-specific ICD-10 codes. Returned patient records were then reviewed for active duty status, branch, age, gender, rank, mechanism, protective equipment, substance use, procedures, and disposition. Profiles of soldiers were reviewed for indication and duration. Patients with profiles were compared to those without profiles. Correlation with age was determined by t-test, correlation with profile length was determined by ANOVA, and correlation with the remaining categorical variables was determined with chi-squared analysis.

RESULTS

Eight hundred and thirty-two service members were reviewed. One hundred and eight (13%) soldiers had a profile. Patients were 23.2% female with no difference between the two groups. Patients were an average of 28.7 years old. The most common mechanisms were physical training (PT) (33.1%) and falls (12.9%). Physical training and motor vehicle collisions were more common in the profile group. Combatives and crush injuries of the hand were less common in the profile group. Major procedures were more common in the profile group, and minor procedures were less common. Admissions, quarters, immediate referrals, and release without limitations were more common in the profile group. The mean duration of profiles was 48.9 days, and 7.4% were permanent.

CONCLUSIONS

Non-battle injuries in the garrison setting are a significant threat to readiness. This analysis of acute traumatic injuries suggests that mechanism of injury was similar to previous reports with PT and falls being most common. Interventions should be targeted at PT and motor vehicle collisions as these were more common in the profile group. This series is also similar to previous reports that extremity injuries are the most common cause of profiles. However, TBIs were more common in our analysis. Further research that encompasses all garrison MTF acute traumatic injuries is needed to define the true impact on readiness and guide development of injury prevention strategies.

The Prevalence of Blood-Borne Pathogens in Maxillofacial Trauma Patients

BACKGROUND

Blood-borne pathogen infections (BPIs), caused by the human immunodeficiency virus, hepatitis C and hepatitis B viruses pose an occupational hazard to healthcare workers. Facial trauma reconstruction surgeons may be at elevated risk because of routine use of sharps, and a higher than average incidence of BPIs in the trauma patient population.

METHODS

The authors retrospectively reviewed health records of patients admitted to a level 1 trauma center with a facial fracture between January 2010 and December 2015. Patient demographics, medical history, mechanism of injury, type of fracture, and procedures performed were documented. The authors detemined the frequency of human immunodeficiency virus, hepatitis B, and hepatitis C diagnosis and utilized univariable/multivariable analyses to identify risk factors associated with infection in this population.

RESULTS

In total, 4608 consecutive patients were included. Infections were found in 4.8% (n = 219) of patients (human immunodeficiency virus 1.6%, hepatitis C 3.3%, hepatitis B 0.8%). 76.3% of BPI patients in this cohort were identified by medical history, while 23.7% were diagnosed by serology following initiation of care. 39.0% of all patients received surgical treatment during initial hospitalization, of whom 4.3% had a diagnosed BPI. History of intravenous drug use (odds ratio [OR] 6.79, P < 0.001), assault-related injury (OR 1.61, P = 0.003), positive toxicology screen (OR 1.56, P = 0.004), and male gender (OR 1.53, P = 0.037) were significantly associated with a BPI diagnosis.

CONCLUSION

Patients presenting with facial fractures commonly harbor a BPI. The benefit of early diagnosis and risk to surgical staff may justify routine screening for BPI in high risk facial trauma patients (male, assault-related injury, and history of intravenous drug use).

Designing an Information and Communications Technology Tool With and for Victims of Violence and Their Case Managers in San Francisco: Human-Centered Design Study

Background

Violence is a public health problem. Hospital-based violence intervention programs such as the San Francisco Wraparound Project (WAP) have been shown to reduce future violent injury. The WAP model employs culturally competent case managers who recruit and enroll violently injured patients as clients. Client acceptance of the WAP intervention is variable, and program success depends on streamlined, timely communication and access to resources. High rates of smartphone usage in populations who are at risk for violent reinjury create an opportunity to design a tailored information and communications technology (ICT) tool to support hospital-based violence intervention programs.

Objective

Current evidence shows that ICT tools developed in the health care space may not be successful in engaging vulnerable populations. The goal of this study was to use human-centered design methodology to identify the unique communication needs of the clients and case managers at WAP to design a mobile ICT.

Methods

We conducted 15 semi-structured interviews with users: clients, their friends and families, case managers, and other stakeholders in violence intervention and prevention. We used a human-centered design and general inductive approach to thematic analysis to identify themes in the qualitative data, which were extrapolated to insight statements and then reframed into design opportunities. Wireframes of potential mobile ICT app screens were developed to depict these opportunities.

Results

Thematic analysis revealed four main insights that were characterized by the opposing needs of our users. (1) A successful relationship is both professional and personal. Clients need this around the clock, but case managers can only support this while on the clock. (2) Communications need to feel personal, but they do not always need to be personalized. (3) Healing is a journey of skill development and lifestyle changes that must be acknowledged, monitored, and rewarded. (4) Social networks need to provide peer support for healing rather than peer pressure to propagate violence. These insights resulted in the following associated design opportunities: (1) Maximize personal connection while controlling access, (2) allow case managers to personalize automated client interactions, (3) hold clients accountable to progress and reward achievements, and (4) build a connected, yet confidential community.

Conclusions

Human-centered design enabled us to identify unique insights and design opportunities that may inform the design of a novel and tailored mobile ICT tool for the WAP community.

A technology-augmented intervention to prevent peer violence and depressive symptoms among at-risk emergency department adolescents: Protocol for a randomized control trial

BACKGROUND

Peer violence and depressive symptoms are increasingly prevalent among adolescents, and for many, use the emergency department (ED) as their primary source of healthcare. Brief in-person interventions and longitudinal text-message-based interventions are feasible, acceptable, and may be effective in reducing peer violence and depressive symptoms when delivered in the ED setting. This paper presents the study design and protocol for an in-ED brief intervention (BI) and text messaging program (Text).

METHODS

This study will be conducted in a pediatric ED which serves over 50,000 pediatric patients per year. Recruitment of study participants began in August 2018 and anticipated to continue until October 2021. The study will enroll 800 adolescents (ages13-17) presenting to the ED for any reason who self-report past-year physical peer violence and past-two week mild-to-moderate depressive symptoms. The study will use a factorial randomized trial to test both overall intervention efficacy and determine the optimal combination of intervention components. A full 2 × 2 factorial design randomizes patients at baseline to 1) BI or no BI; and 2) Text or no Text. Peer violence and depressive symptoms improvements will be measured at 2, 4, and 8 months through self-report and medical record review.

DISCUSSION

This study has important implications for the progress of the greater field of mobile health interventions, as well as for adolescent violence and depression prevention in general. This proposal has high clinical and public health significance with high potential scalability, acceptability, and impact.
