Impact of a Prison Therapeutic Diversion Unit on Mental and Behavioral Health Outcomes

Prior incarceration, restrictive housing, and posttraumatic stress disorder symptoms in a community sample of persons who use drugs

BACKGROUND

Criminalization of drugs in the United States (US) has extensive consequences for people who use drugs (PWUD). Incarceration and substance use overlap with 65% of the US prison population meeting substance use disorder (SUD) criteria. Exposure to the criminal-legal system negatively impacts the health of PWUD. PTSD is commonly comorbid with SUDs, and exposure to restrictive housing (RH) during incarceration may worsen mental health. Because PWUD are disproportionately incarcerated, experiences occurring during incarceration, such as RH, may contribute to the development or exacerbation of PTSD and SUDs. This study of PWUD investigated prior criminal-legal system exposure and its association with PTSD symptoms in community-dwelling PWUD.

METHODS

This cross-sectional study recruited PWUD from syringe service programs (SSP). Inclusion criteria were: age 18+, current or past opioid use disorder, and SSP enrollment. Data collected included: sociodemographics; incarceration, substance use, SUD treatment history, and PTSD assessments (Life Events Checklist for DSM-5 and the PTSD Checklist for DSM-5). Bivariate testing and multivariate logistic regression analyses, with probable PTSD as the dependent variable and a three-level variable for criminal legal history as the independent variable, were conducted to determine whether incarceration and RH were associated with probable PTSD.

RESULTS

Of 139 participants, 78% had an incarceration history with 57% of these having a history of RH. 57% of participants screened positive for probable PTSD, and physical assault was the most common traumatic exposure. Any history of incarceration was not associated with probable PTSD diagnosis; however, in multivariate testing, adjusting for age, sex, and substance use, a history of RH (adjusted odds ratio [aOR]: 3.76, 95% CI 1.27-11.11) was significantly associated with probable PTSD.

CONCLUSIONS

RH and PTSD were both exceptionally common in a sample of SSP participants. RH can be detrimental to physical and mental health. Clinicians and policy makers may not consider incarceration as a traumatic experience for PWUD; however, our data suggest that among highly marginalized PWUD, prior exposure to incarceration and RH may add an additional burden to their daily struggles, namely PTSD.

Suicide Mortality Among Formerly Incarcerated People Compared With the General Population in North Carolina, 2000-2020

We aimed to compare rates and characteristics of suicide mortality in formerly incarcerated people with those of the general population in North Carolina. We conducted a retrospective cohort study of 266,400 people released from North Carolina state prisons between January 1, 2000, and March 1, 2020. Using direct and indirect standardization by age, sex, and calendar year, we calculated standardized suicide mortality rates and standardized mortality ratios comparing formerly incarcerated people with the North Carolina general population. We evaluated effect modification by race/ethnicity, sex, age, and firearm involvement. Formerly incarcerated people had approximately twice the overall suicide mortality of the general population for 3 years after release, with the highest rate of suicide mortality being observed in the 2-week period after release. In contrast to patterns in the general population, formerly incarcerated people had higher rates of non-firearm-involved suicide mortality than firearm-involved suicide mortality. Formerly incarcerated female, White and Hispanic/Latino, and emerging adult people had a greater elevation of suicide mortality than their general-population peers compared with other groups. These findings suggest a need for long-term support for formerly incarcerated people as they return to community living and a need to identify opportunities for interventions that reduce the harms of incarceration for especially vulnerable groups.

Evaluation of a prison violence prevention program: impacts on violent and non-violent prison infractions

BACKGROUND

Individuals who commit acts of violence in prisons are often placed in highly controlled environments called restrictive housing (i.e., solitary confinement), which can have severe physical and mental health consequences and does not reduce violence. As such, North Carolina prisons have introduced the rehabilitative diversion unit (RDU) to reduce the use of restrictive housing and reduce violence in prison.

METHODS

We evaluated the effect of the RDU on prison infractions. We compared rates of infractions by type (including violent infractions) among men enrolled in the RDU and men who were eligible for the RDU but placed in restrictive housing for control purposes (RHCP). We also evaluated sustained program impacts by comparing the hazard of first infraction among these same two groups of men after program completion, when they had returned to the general prison population. Finally, we compared the hazard of first promotion to a less restrictive custody level (medium custody) when these men had returned to the general prison population.

RESULTS

The primary analytic cohort was made up of 3128 men contributing 897,822 person-days. Adjusted rates of violent infractions were lower in the RDU than in RHCP (adjusted rate ratio: 0.6; 95% CI: 0.4, 1.1). All other categories of infractions, including drug-related infractions, occurred at higher rates during RDU, as compared to RHCP. In analyses of sustained program impacts, for most categories of infractions, there were no differences in the hazard of first infraction post-RDU and post-RHCP. However, the hazard of violent infraction post-RDU was higher (adjusted hazard ratio: 2.1; 95% CI: 1.1, 4.0) than post-RHCP. The hazard of promotion to a less restrictive custody level was higher post-RDU (adjusted hazard ratio: 17.4; 95% CI: 7.2, 42.2) than post-RHCP.

CONCLUSIONS

We found the RDU program may be effective in reducing violence for men enrolled in the program, but that these benefits were not sustained. Continued programming may be a useful tool to transition men from the programmatically intensive environment of the RDU to the general prison population. Additionally, we recommend the expansion of evidence-based treatment for substance use disorder.

Sustained impacts of North Carolina prison therapeutic diversion units on behavioral outcomes, mental health, self-injury, and restrictive housing readmission

Therapeutic Diversion Units (TDUs) in North Carolina prisons are intended to reduce cycling of individuals with mental health conditions through restrictive housing (i.e., solitary confinement). This paper investigates if previously identified benefits of TDU are sustained when individuals return to the general prison population. Using administrative data on 3170 people, we compare individuals placed in TDUs to TDU-eligible individuals (i.e., individuals with mental health needs) placed in restrictive housing. We use survival analysis methods to estimate hazard ratios (HRs) with confidence intervals (CIs), controlling for confounders. Compared to restrictive housing placement, TDU placement reduced the hazard of infractions (HR: 0.66; 95% CI: 0.52, 0.84) and subsequent restrictive housing placement (HR: 0.64; 95% CI: 0.55, 0.73) but increased the hazard of self-harm (HR: 2.67; 95% CI: 1.66, 4.29) upon program release to the general prison population. These findings suggest a need for additional investments and research on restrictive housing diversion programming, including post-diversion program supports.
