The effect of previous traumatic injury on homicide risk

Impact of novel psychosocial programming on readmission and recidivism rates among patients with violence-related trauma

INTRODUCTION

The Victims of Crime Advocacy and Recovery Program (VOCARP) provides advocacy, mental health resources, and educational materials. This study will report complications, readmissions, and recidivism among crime victims, and who used or did not use victim services.

MATERIALS AND METHODS

Patients engaged with programming from 3/1/17 until 12/31/18 were included. Control groups were patients injured by violent trauma without VOCARP use (N = 212) and patients injured by unintentional injuries (N = 201). Readmissions, complications, reoperations, and trauma recidivism were reported.

RESULTS

1019 patients (83%) used VOCARP. VOCARP users were less often male (56% vs. 71%), less commonly married (12% vs. 41%), and had fewer gunshot wounds (GSWs, 26% vs. 37%) and sexual assaults (4.1% vs. 8%), all p < 0.05. Of all 1,423 patients, 6.6% had a readmission and 7.4% developed a complication. VOCARP patients had fewer complications (4.5% vs. 13.7%), infections (2% vs. 9%), wound healing problems (1% vs. 3.3%), and deep vein thromboses (0.3% vs. 1.9%), all p < 0.05, but no differences in unplanned operations (4.5%). GSW victims had the most complications, readmissions, and unplanned surgeries. Prior trauma recidivism was frequent among all groups, with crime victim patients having 40% prior violence-related injury (vs 9.0% control, p < 0.0001). Trauma recidivism following VOCARP use occurred in 8.5% (vs 5.7% for non-users, p = 0.16).

CONCLUSION

Crime victims differ from other trauma patients, more often with younger age, single marital status, and unemployment at baseline. Complications were lower for VOCARP patients. GSW patients had the most complications, readmissions, and unplanned secondary procedures, representing a population for future attention.

Implementation of programming for survivors of violence-related trauma at a level 1 trauma center

Background

Prior investigation of violence intervention programs has been limited. This study will describe resources offered by Victims of Crime Advocacy and Recovery Program (VOCARP), their utilization, and effect on recidivism.

Methods

VOCARP was established in 2017 at our center, and all patients who engaged with programming (n=1019) were prospectively recorded. Patients are offered services in the emergency department, on inpatient floors and at outpatient clinic visits. Two control groups (patients sustaining violent injuries without VOCARP use (n=212) and patients with non-violent trauma (n=201)) were similarly aggregated.

Results

During 22 months, 96% of patients accepted education materials, 31% received financial compensation, 27% requested referrals, and 22% had crisis interventions. All other resources were used by <20% of patients. Patients who used VOCARP resources were substantially different from those who declined services; they were less often male (56% vs. 71%), more often single (79% vs. 51%), had greater unemployment (63% vs. 51%) and were less frequently shot (gunshot wound: 26% vs. 37%), all p<0.05. Overall recidivism rate was 9.4%, with no difference between groups. Use of mental health services was linked to lower recidivism rates (4.4% vs. 11.7%, p=0.016). While sexual assault survivors who used VOCARP resources had lower associated recidivism (2.4% vs. 12%, p=0.14), this was not statistically significant.

Discussion

This represents the largest violence intervention cohort reported to date to our knowledge. Despite substantial engagement, efficacy in terms of lower recidivism appears limited to specific subgroups or resource utilization.

Evaluation of Injury Recidivism Using the Electronic Medical Record

BACKGROUND

Traumatic injuries remain one of the leading causes of death in the United States. Patients who survive traumatic injuries but return to the emergency department with repeat injuries are said to suffer from injury recidivism. Numerous studies have described trends in injury recidivism using trauma registry and survey data. To our knowledge, no prior study has leveraged electronic medical record (EMR) data to characterize injury recidivism. The EMR is potentially more comprehensive as it contains details of patients who visited the emergency department after injury but did not meet the criteria for inclusion in the trauma registry. Such injuries could be predictive of future recidivism. We therefore aimed to describe patterns of injury recidivism seen at a Level 1 trauma center using the EMR.

METHODS

A retrospective review was conducted of all injury-related encounters between January 2016 and December 2019. Manual review was conducted of all recidivistic encounters with < 11 months between encounters to ensure the recidivistic encounter was not a sequela of the index visit. A general estimating equation logistic regression adjusted for age, race, sex, and insurance payor, estimated odds ratios (ORs) and 95% confidence intervals (CIs) for the association between injury mechanism and odds of recidivistic encounter.

RESULTS

A total of 20,566 index encounters was included during the study period. Of the 20,566 encounters, 7.6% (n = 1570) had a recidivistic encounter during the study period, half of which (n = 781) occurred within the first year of the index encounter. An over two-fold increased odds of recidivism was observed for blunt assault encounters (OR 2.53, 95% CI 2.03-3.15) and unintentional falls (OR 2.10, 95% CI 1.76-2.52). For both mechanisms, this increase was observed across the three years following the index encounter.

CONCLUSIONS

Our study found that patients with assault injuries have the highest odds of injury recidivism and assault-related recidivistic encounters. These results demonstrate the feasibility and utility of incorporating EMR data, and suggest that the development of targeted interventions focused on mitigating assault injuries, such as hospital-based violence intervention programs, should be considered in our region.

"You don't want anyone who hasn't been through anything telling you what to do, because how do they know?": Qualitative analysis of case managers in a hospital-based violence intervention program

STATEMENT OF PURPOSE

Intentional violent injury is a leading cause of disability and death among young adults in the United States. Hospital-based violence intervention programs (HVIPs), which strive to prevent re-injury through intensive case management, have emerged as a successful and cost-effective strategy to address this issue. Despite the importance of strong therapeutic relationships between clients and their case managers, specific case manager behaviors and attributes that drive the formation of these relationships have not been elucidated.

METHODS

A qualitative analysis with a modified grounded theory approach was conducted to gain insight into what clients perceive to be crucial to the formation of a strong client-case manager relationship. Twenty-four semi-structured interviews were conducted with prior clients of our hospital's HVIP. The interviews were analyzed using constant comparison method for recurrent themes.

RESULTS

Several key themes emerged from the interviews. Clients emphasized that their case managers must: 1) understand and relate to their sociocultural contexts, 2) navigate the initial in-hospital meeting to successfully create connection, 3) exhibit true compassion and care, 4) serve as role models, 5) act as portals of opportunity, and 6) engender mutual respect and pride.

CONCLUSIONS

This study identifies key behaviors of case managers that facilitate the formation of strong therapeutic relationships at the different stages of client recovery. This study's findings emphasize the importance of case managers being culturally aligned with and embedded in their clients' communities. This work can provide a roadmap for case managers to form optimally effective relationships with clients.

A decade of hospital-based violence intervention: Benefits and shortcomings

INTRODUCTION

Initial analyses of hospital-based violence intervention programs (VIPs) have demonstrated decreased violent injury recidivism. Long-term VIP performance has not been assessed. Violence intervention program quality improvement requires evaluation to identify shortcomings and client subpopulations warranting additional resources. We evaluated our case manager-based VIPs to identify modifiable risk factors that most impact violent injury recidivism and determine subpopulations that need modification of targeted services.

METHODS

Data on demographic variables, socioeconomic factors, needs, and injury recidivism from 2005 to 2014 were collected through our VIP database. Possible client needs included housing, education, employment, court advocacy, driver's license obtainment, and "other." Case managers assessed needs as "not needed," "identified (unmet)," and "met." χ And nonparametric tests were used to identify factors associated with recidivism reduction.

RESULTS

Over the 10-year period, 466 clients were enrolled in VIP. During the program period, the violent reinjury rate was 4%, as compared with a historical control of 8% from 2000 to 2004. Women had lower rates of reinjury than men (3% vs 13%, respectively, p = 0.023). Blacks had the lowest recidivism (2%, p < 0.0001), whereas a higher rate (11%) was observed among Latinos. Although a minority of clients (5%), 100% of white clients were reinjured. Mental health services (51%), victim-of-crime compensation (48%), employment (36%), and housing (30%) were the most frequently identified needs. Expressing the need for education was significantly associated with likelihood of reinjury, an effect that was completely reversed when the need was met.

CONCLUSION

This evaluation of a VIP demonstrates sustained recidivism reduction and success in addressing client needs from a traditionally underserved population. Efforts to identify and address root causes of Latino and white client reinjury should be increased. Violence intervention program prioritization of housing needs may reduce future reinjury. This study demonstrating sustainable success underscores the importance of increased integration of VIP into trauma centers nationally.

Recurrent violent injury: magnitude, risk factors, and opportunities for intervention from a statewide analysis

INTRODUCTION

Although preventing recurrent violent injury is an important component of a public health approach to interpersonal violence and a common focus of violence intervention programs, the true incidence of recurrent violent injury is unknown. Prior studies have reported recurrence rates from 0.8% to 44%, and risk factors for recurrence are not well established.

METHODS

We used a statewide, all-payer database to perform a retrospective cohort study of emergency department visits for injury due to interpersonal violence in Florida, following up patients injured in 2010 for recurrence through 2012. We assessed risk factors for recurrence with multivariable logistic regression and estimated time to recurrence with the Kaplan-Meier method. We tabulated hospital charges and costs for index and recurrent visits.

RESULTS

Of 53 908 patients presenting for violent injury in 2010, 11.1% had a recurrent violent injury during the study period. Trauma centers treated 31.8%, including 55.9% of severe injuries. Among recurrers, 58.9% went to a different hospital for their second injury. Low income, homelessness, Medicaid or uninsurance, and black race were associated with increased odds of recurrence. Patients with visits for mental and behavioral health and unintentional injury also had increased odds of recurrence. Index injuries accounted for $105 million in costs, and recurrent injuries accounted for another $25.3 million.

CONCLUSIONS

Recurrent violent injury is a common and costly phenomenon, and effective violence prevention programs are needed. Prevention must include the nontrauma centers where many patients seek care.

Cost-benefit analysis simulation of a hospital-based violence intervention program

BACKGROUND

Violent injury is a major cause of disability, premature mortality, and health disparities worldwide. Hospital-based violence intervention programs (HVIPs) show promise in preventing violent injury. Little is known, however, about how the impact of HVIPs may translate into monetary figures.

PURPOSE

To conduct a cost-benefit analysis simulation to estimate the savings an HVIP might produce in healthcare, criminal justice, and lost productivity costs over 5 years in a hypothetical population of 180 violently injured patients, 90 of whom received HVIP intervention and 90 of whom did not.

METHODS

Primary data from 2012, analyzed in 2013, on annual HVIP costs/number of clients served and secondary data sources were used to estimate the cost, number, and type of violent reinjury incidents (fatal/nonfatal, resulting in hospitalization/not resulting in hospitalization) and violent perpetration incidents (aggravated assault/homicide) that this population might experience over 5 years. Four different models were constructed and three different estimates of HVIP effect size (20%, 25%, and 30%) were used to calculate a range of estimates for HVIP net savings and cost-benefit ratios from different payer perspectives. All benefits were discounted at 5% to adjust for their net present value.

RESULTS

Estimates of HVIP cost savings at the base effect estimate of 25% ranged from $82,765 (narrowest model) to $4,055,873 (broadest model).

CONCLUSIONS

HVIPs are likely to produce cost savings. This study provides a systematic framework for the economic evaluation of HVIPs and estimates of HVIP cost savings and cost-benefit ratios that may be useful in informing public policy decisions.
