Differences between older and younger adults in residential treatment for co-occurring disorders

Demographic and Clinical Correlates of Treatment Completion among Older Adults with Heroin and Prescription Opioid Use Disorders

In this study using 2015-2018 Treatment Episode Data Set-Discharge (TEDS-D) cases age 55+ for heroin (N = 101,524) or prescription opioids (PO; N = 25,510) as the primary substance, we examined treatment completion rates and correlates. We fit separate logistic regression models for heroin and PO cases with treatment completion status (completed vs. discontinued due to dropout/termination/other reasons) for each treatment setting (detoxification, residential rehabilitation, and outpatient) as the dependent variable. Results show that detoxification cases had the highest completion rates and outpatient cases had the lowest (14.8% for heroin and 24.0% for PO cases). A consistently significant correlate of treatment completion was legal system referral for heroin cases and having a bachelor's degree for PO cases. Medication-assisted therapy was associated with higher odds of completing residential treatment for both types of opioids but lower odds of completing detoxification and outpatient treatment. Treatment duration >30 days tended to have higher odds of completion. PO cases age 65+ had higher odds of completing residential treatment than cases age 55-64. Racial/ethnic minorities tended to have lower odds of outpatient treatment completion. Study findings underscore the importance of helping older adults complete treatment, especially those who are racial/ethnic minorities and receiving outpatient treatment.

Exploring life-course patterns of substance abuse: a qualitative study

OBJECTIVES

This research sought to examine how older adults with substance abuse issues understand the pattern of their use. Qualitative interviews explored: (1) Whether self-reported age of onset of substance abuse in fact aligned with the age when use became problematic; (2) Patterns of substance use over the life-course; (3) Precipitants of substance use throughout the lifespan; (4) Factors that prevented identification of problem use; (5) How participants came to recognize that their substance use was problematic.

METHOD

Participants were 11 men and 9 women aged 62-78 years (M = 69.80, SD = 3.86) who were clients of an older adult substance abuse treatment program. Semi-structured interviews were conducted and transcribed for thematic analysis.

RESULTS

Interview data revealed discrepancies between self-identified age of substance abuse onset and reported problematic use throughout the lifetime. Thematic analysis revealed factors that contributed to participants not recognizing problem use earlier in life, such as normalizing and minimizing the impact of use and lack of severe consequences earlier in life. Additionally, factors that led to increased use (i.e. retirement, grief), and to recognition of problem use and treatment-seeking were identified (i.e. social, financial, legal, and health problems).

CONCLUSION

In general, self-reported age of substance abuse onset and patterns of substance abuse were highly variable across participants. These results have implications for assessment of substance use among older adults, as well as preventative efforts to decrease risk of substance abuse.

Evaluating substance use treatment efficacy for younger and older adults

The purpose of this study was to examine the differential efficacy of aftercare substance use treatments for younger (below 40, n = 107) versus older (40+, n = 114) adults (N = 221), using data from a randomized controlled trial in a community-based substance abuse treatment center. The younger adult sample had a mean age of 28.9 while the older adult sample had a mean age of 48.1. Primary outcomes were rates of abstinence and percent use days at 1-year follow-up. Outcomes were compared between standard cognitive behavioral relapse prevention (RP), Mindfulness-Based Relapse Prevention (MBRP), and 12-step-based treatment as usual (TAU). Results showed significant differences by treatment in the older, but not in younger, subsample of participants. Specifically, the older participants in MBRP had significantly higher abstinence rates compared with those in TAU. Further, the older individuals in MBRP had a significantly lower percent of days on which they used compared with those in TAU and RP. Overall, findings suggest that age group may impact aftercare treatment substance use outcomes.

Older marijuana users in substance abuse treatment: Treatment settings for marijuana-only versus polysubstance use admissions

OBJECTIVE

Growing numbers of older adult marijuana users make understanding the marijuana-related treatment needs and treatment-related characteristics of this age group increasingly important. In this study, we examined four types of marijuana-involved admissions (marijuana as the only substance; marijuana as the primary substance with other secondary/tertiary substances; marijuana as the secondary substance; and marijuana as the tertiary substance) by treatment setting.

METHODS

Data came from the 2012-2017 Treatment Episode Data Set-Admissions (TEDS-A), which includes 851,652 admissions by those aged 55+. Using multinomial logistic regression analysis, we focused on the 120,286 marijuana-involved admissions to test the hypothesis that polysubstance use would be associated with a higher likelihood of using detoxification and rehabilitation settings than ambulatory/outpatient settings.

RESULTS

Of all marijuana-involved admissions, 7.5% were marijuana-only, 12.7% were marijuana-primary, 58.4% were marijuana-secondary, and 21.4% were marijuana-tertiary admissions. Compared to marijuana-only admissions, admissions involving other substances were associated with a higher likelihood of detoxification and rehabilitation than ambulatory/outpatient treatment (e.g., RRR = 5.79, 95% CI = 5.08-6.61 for detoxification and RRR = 3.19, 95% CI = 2.89-3.52 for rehabilitation among marijuana-tertiary admissions). Referral source, first age of marijuana use, race/ethnicity, and homelessness were significant covariates.

CONCLUSIONS

Given increasing numbers of older-adult marijuana users, healthcare providers should screen older adults for marijuana and other substance use, and substance abuse treatment programs should become more responsive to older adults' needs.

Family Behavior Therapy for Alcohol and Drug Problems in Later-Life

Alcohol and drug use problems among older individuals are a growing public health concern. However, few treatments have been developed for this population, despite an emerging body of literature suggesting that older substance users are more likely to benefit from interventions tailored to meet their specific needs. In particular, older adults with a history of substance abuse have expressed a preference for treatments that focus on financial problems, physical health, and mobility issues, and make attempts to prescriptively involve supportive others in treatment. To address these needs, we developed a modified version of Family Behavior Therapy (FBT) for older individuals with substance use problems that involves participation from significant others and covers skills that are relevant to an older clientele. This modified form of FBT is illustrated through the case of Jack-a 55-year-old man with a longstanding addiction to methamphetamine. After completing 16 sessions, Jack's alcohol and drug use was substantially reduced, and he reported strong confidence in his ability to resist substance use in the future. Despite this promising first case, further work is needed to fully examine the efficacy of this modified version of FBT for older individuals with substance use problems.

Gender Comparison in Referrals and Treatment Completion to Residential and Outpatient Alcohol Treatment

BACKGROUND

Residential treatment for alcoholism is associated with high completion rates for clients, yet there appear to be gender disparities in patient referrals and treatment completion rates. We studied whether (A) gender is associated with differential patient placement to outpatient vs. residential treatment facilities and (B) completion rates differ by gender.

METHODS

In this cross-sectional study, we analyzed the admission and discharge data from 185 publicly funded substance abuse treatment facilities across Los Angeles County between 2005 and 2010.

RESULTS

Among the 33,745 studied cases, women were referred to residential treatment facilities less frequently than men (75% vs. 66%). The adjusted results derived from logistic regression models confirmed that females were more likely to be referred to outpatient treatment than to residential treatment facilities (odds ratio [OR]: 1.15, 95% confidence interval [CI]: 1.05–1.26). In addition, we observed that compared to White/Caucasian patients, all other races were associated with more referral to outpatient facilities (ie, less referral to residential facilities), indicating a racial disparity on the top of the observed gender disparity. However, there was no significant link between gender and treatment completion rates (OR: 0.93, 95% CI: 0.86–1.00).

CONCLUSIONS

Women seem to have treatment completion rates comparable to men, yet they are less likely to be referred to residential treatment facilities. Hence, there still remains a gender disparity in alcoholic patient referrals. Further studies should delineate which specific therapeutic aspects and programmatic components of women-focused treatments are essential to augment positive treatment outcomes.
