Completion rates and psychosocial intervention effectiveness in an Australian substance use therapeutic community

Systematic review of treatment completion rates and correlates among young people accessing alcohol and other drug treatment

BACKGROUND AND AIMS

Treatment completion is associated with improved alcohol and other drug (AOD) treatment outcomes. Unfortunately, treatment disengagement is common, particularly among young people. We reviewed and synthesised research on AOD treatment completion and/or early disengagement among young people.

METHODS

We conducted a systematic review and meta-analysis of studies reporting on completion rates and/or early disengagement from psychosocial AOD treatment among adolescents and young adults. An overall estimated treatment completion rate was calculated using inverse-variance random effects meta-analysis, and random-effects meta-regression was used to identify between-study level moderators of completion rate. We completed a narrative review summarising literature on early treatment disengagement and within-study level correlates of treatment completion. Study quality was assessed using the EPHPP.

RESULTS

Of the 6158 studies screened, we retained 410 for full text review and included 98 studies in the review. Treatment completion rates were reported in 88 studies, and early disengagement rates were reported in 13. The estimated overall treatment completion rate was 59 % (95 % CI=57-61 %), with experimental studies reporting higher rates of completion than observational studies. There was limited evidence for demographic or substance-related correlates of treatment completion. Contingency management was associated with increased completion rates, as was family-based intervention.

CONCLUSIONS

Disengagement from AOD treatment among youth populations is common and contributes to poor treatment outcomes. Existing research has yielded little consensus on the factors associated with treatment completion. The use of contingency management strategies and involving family/social supports in treatment were identified as potential avenues for promoting ongoing treatment engagement.

Cognitive remediation in residential substance use treatment: A randomized stepped-wedge trial

ABSTRACTExecutive dysfunction is common in individuals with substance use disorder (SUD) and presents a barrier to treatment engagement. The study aimed to investigate the effectiveness of cognitive remediation (CR) for improving executive functioning and treatment retention in patients with SUD, using a stepped-wedge cluster randomized controlled trial. The sample included 527 adults enrolled across ten residential SUD treatment providers in NSW, Australia. The intervention consisted of 12 hours of CR delivered over six weeks in a group format. The comparator was treatment-as-usual (TAU). Primary outcomes included self-reported executive functioning and proportion of treatment completed (PoTC), measured as the number of days in treatment divided by the planned treatment duration. Intention-to-treat analysis did not find significant differences for self-reported executive functioning (mean difference = -2.49, 95%CI [-5.07, 0.09], p = .059) or PoTC (adjusted mean ratio = 1.09, 95%CI [0.88, 1.36], p = .442). Due to high dropout from the intention-to-treat sample (56%) a post-hoc analysis was conducted using a per-protocol approach, in which CR was associated with improved self-reported executive functioning (mean difference = -3.33, 95%CI [-6.10, -0.57], p = .019) and improved likelihood of treatment graduation (adjusted odds ratio = 2.43, 95%CI [1.43, 4.11], p < .001). More research is required to develop a CR approach that results in service-wide treatment effectiveness.

A Web-Based Patient Empowerment to Medication Adherence Program for Patients With Rheumatoid Arthritis: Feasibility Randomized Controlled Trial

BACKGROUND

Living with a chronic illness such as rheumatoid arthritis (RA) requires medications and therapies, as well as long-term follow-up with multidisciplinary clinical teams. Patient involvement in the shared decision-making process on medication regimens is an important element in promoting medication adherence. Literature review and needs assessment showed the viability of technology-based interventions to equip patients with knowledge about chronic illness and competencies to improve their adherence to medications. Thus, a web-based intervention was developed to empower patients living with RA to adhere to their disease-modifying antirheumatic drugs (DMARDs) medication regimen.

OBJECTIVE

This study aims to discuss the intervention mapping process in the design of a web-based intervention that supports patient empowerment to medication adherence and to evaluate its feasibility among patients living with RA.

METHODS

The theory-based Patient Empowerment to Medication Adherence Programme (PE2MAP) for patients with RA was built upon the Zimmerman Psychological Empowerment framework, a web-based program launched through the Udemy website. PE2MAP was developed using a 6-step intervention mapping process: (1) needs assessment, (2) program objectives, (3) conceptual framework to guide the intervention, (4) program plan, (5) adoption, and (6) evaluation involving multidisciplinary health care professionals (HCPs) and a multimedia team. PE2MAP is designed as a 4-week web-based intervention program with a complementary RA handbook. A feasibility randomized controlled trial was completed on 30 participants from the intervention group who are actively taking DMARD medication for RA to test the acceptability and feasibility of the PE2MAP.

RESULTS

The mean age and disease duration of the 30 participants were 52.63 and 8.50 years, respectively. The feasibility data showed 87% (n=26) completed the 4-week web-based PE2MAP intervention, 57% (n=17) completed all 100% of the contents, and 27% (n=8) completed 96% to 74% of the contents, indicating the overall feasibility of the intervention. As a whole, 96% (n=24) of the participants found the information on managing the side effects of medications, keeping fit, managing flare-ups, and monitoring joint swelling/pain/stiffness as the most useful contents of the intervention. In addition, 88% (n=23) and 92% (n=24) agreed that the intervention improved their adherence to medications and management of their side effects, including confidence in communicating with their health care team, respectively. The dos and do nots of traditional Chinese medicine were found by 96% (n=25) to be useful. Goal setting was rated as the least useful skill by 6 (23.1%) of the participants.

CONCLUSIONS

The web-based PE2MAP intervention was found to be acceptable, feasible, and effective as a web-based tool to empower patients with RA to manage and adhere to their DMARD medications. Further well-designed randomized controlled trials are warranted to explore the effectiveness of this intervention in the management of patients with RA.

Profiles of patients with substance-related disorders who dropped out or not from addiction treatment

This longitudinal study identified profiles of patients with substance-related disorders (SRD) who did or did not drop out of specialized addiction treatment, integrating various patterns of outpatient service use. Medical administrative databases of Quebec (Canada) were used to investigate a cohort of 16,179 patients with SRD who received specialized addiction treatment. Latent class analysis identified patient profiles, based on multi-year outpatient service use. Four patient profiles related to treatment dropout were identified: patients who did not drop out and were low service users (Profile 1); patients who did not drop out and were high service users (Profile 2); patients who dropped out and were low service users (Profile 3); patients who dropped out and were high service users (Profile 4). Profile 1 had the best health and social conditions, while Profile 4 had the worst. The risks of being frequent emergency department users, being hospitalized or dying were highest in Profile 4, followed by Profiles 3, 2 and 1. Assertive treatment programs may be suited to Profile 4 and intensive case management programs to Profile 3. Collaborative care with higher psychosocial interventions and regularity of care may be extended to Profile 2 and interventions integrating motivational treatment to Profile 1.

Gender and Age Bias in the Evaluation of Suicide Attempt Behavior in an Emergency Department

We aimed to investigate whether demographic characteristics such as age and gender of attempted suicide patients are associated with bias in the post-Emergency Department (ED) discharge program manager's evaluation of genuineness of the patients' suicide attempts. In the ED-Based Post-Suicide Attempt Case Management (ED-PSACM) program, the manager interviews patients with suicide attempts and makes subjective judgement on the patient's genuineness of the suicide attempt. After patients' discharge, the manager provides follow-up post-discharge care management services. Compared to ≥ 65 years old male patients as a reference group, 18-39 years old female patients showed significantly lower judgment for a genuine suicide attempt (OR = 0.34; 95% CI 0.12-0.81). Other groups did not show significant differences from the reference group. Our study result suggests the possibility of the effects of bias on young females on the judgment of the suicide attempt genuineness. Medical staff and interventions managers in the ED should be concerned to avoid knowledge-mediated bias, especially by gender and age.

Predictors of dropout from treatment among patients using specialized addiction treatment centers

OBJECTIVES

This study investigated the use of outpatient care, and sociodemographic and clinical characteristics of patients with substance-related disorders (SRD) to predict treatment dropout from specialized addiction treatment centers. The study also explored risks of adverse outcomes, frequent emergency department (ED) use (3+ visits/year), and death, associated with treatment dropout within the subsequent 12 months.

METHODS

The study examined a cohort of 16,179 patients who completed their last treatment episode for SRD between 2012 and 13 and 2014-15 (financial years: April 1 to March 31) in 14 specialized addiction treatment centers using Quebec (Canada) health administrative databases. We used multivariable logistic regressions to measure risk of treatment dropout (1996-96 to 2014-15), while we used survival analysis controlling for sex and age to assess the odds of frequent ED use and death in 2015-16.

RESULTS

Of the 55 % of patients reporting dropout from SRD treatment over the 3-year period, 17 % were frequent ED users, and 1 % died in the subsequent 12 months. Patients residing in the most socially deprived areas, having polysubstance-related disorders or personality disorders, and having previously dropped out from specialized addiction treatment centers had increased odds of current treatment dropout. Older patients, those with a history of homelessness, past SRD treatment, or more concurrent outpatient care outside specialized addiction treatment centers had decreased odds of treatment dropout. Patients who dropped out were subsequently at higher risk of frequent ED use and death.

CONCLUSIONS

This study highlighted that patients with more severe problems and previous dropout may need more sustained and adequate help to prevent subsequent treatment dropout. Specialized addiction treatment centers may consider enhancing their follow-up care of patients over a longer duration and better integrating their treatment with other outpatient care resources to meet the multiple needs of the more vulnerable patients using their services.

A realist review of residential treatment for adults with substance use disorder

ISSUES

Completion of residential treatment for substance use disorder (SUD) relates to improvements in substance use and mental health. Findings from systematic reviews have been equivocal about which interventions work best for clients. There has been limited attention to the theories that explain the effectiveness of residential treatment.

APPROACH

We conducted a realist review of the literature to identify program theories that would explain successful and unsuccessful outcomes from residential treatment for SUD. The unit of analysis was context-mechanism-outcome (CMO). Inclusion criteria were studies of residential treatment of more than 30 days for adults with SUD. Pharmacological studies were excluded.

KEY FINDINGS

We identified 24 studies from 5748 screened. The studies were from settings comprising Indigenous programs, faith-based programs, psycho-social interventions and therapeutic communities and were conducted in North America, Scandinavia, Continental Europe and Australasia. We chose six CMO configurations as the best explanations for outcomes from residential treatment. Theories that best explained the mechanisms of change were the need to belong, meaning in life, and self-determination theory.

IMPLICATIONS

Previous research has noted similar outcomes from different residential treatment interventions, but has not been able to explain these similarities. In contrast, our findings suggest that the outcomes can be explained by causal mechanisms that apply across all programs, regardless of the philosophy of treatment.

CONCLUSION

We identified six CMO configurations whose mechanisms of change could be explained by three overarching theories-the need to belong, meaning in life and self-determination theory. The findings apply across ethnicities and genders.

What Client Demographic, Substance Use, Mental Health, Treatment, and Psychological Variables Predict Residential Treatment Completion for Substance Use Disorders?

Residential treatment is a common option for individuals with moderate to severe substance use disorders. In a cohort of individuals who accessed residential treatment, we investigated client demographic, substance use, mental health, treatment, and psychological predictors of treatment completion. Participants were a retrospective cohort of 1056 (15–69 years) individuals admitted to residential treatment facilities across Queensland, Australia, from January 2014 to December 2016. Participant characteristic information was obtained at admission, including the Depression Anxiety Stress Scale 21 (DASS-21). A multiple logistic regression model was conducted with treatment completion as the outcome. The overall rate of treatment completion was 14.3%. Mild to moderate (aOR = 0.48 [0.28–0.84], p = .010) and severe to extremely severe (aOR = 0.35 [0.17–0.74], p = .006) stress on the DASS-21 at service entry was significantly associated with a lower likelihood of treatment completion. Participants with higher levels of stress at service entry were less likely to complete treatment, representing a missed opportunity to provide targeted support during high-risk periods for individuals with substance use disorders. Further research investigating the nature and causes of stress in-between, during, and following presentations to residential treatment is needed.

Polysubstance use in young people accessing residential and day-treatment services for substance use: substance use profiles, psychiatric comorbidity and treatment completion

BACKGROUND AND AIMS

People with substance use disorders (SUDs) frequently present to treatment with polysubstance use and mental health comorbidities. Different combinations of substance use and mental health problems require different treatment approaches. Our study aimed to: (i) identify the shared substance use classes among young people at treatment admission, (ii) determine which mental health symptoms, quality of life (QoL) and service types were associated with the identified substance use classes, and (iii) prospectively determine which substance use classes and service types were more likely to complete treatment.

DESIGN

Cross-sectional and prospective study using service and outcome data.

SETTING

Substance use treatment services in Queensland and New South Wales, Australia.

PARTICIPANTS

De-identified service and outcome measure data were extracted from the files of 744 clients aged 18-35 years (48% male) admitted into seven residential and four day-treatment programmes.

MEASUREMENTS

Substance use and severity among tobacco, alcohol, cannabis, cocaine, amphetamine-type stimulants, opioids, sedatives and inhalants. Other variables included: depression, anxiety, post-traumatic stress and psychotic symptoms, as well as QoL.

FINDINGS

Latent class analysis identified three polysubstance use classes: wide-ranging polysubstance users (WRPU; 22.45%), primary amphetamine users (56.45%) and alcohol and cannabis users (21.10%). The WRPU class had higher odds of psychotic symptoms than the alcohol and cannabis use class [odds ratio (OR) = 1.30; 95% confidence interval (CI) = 1.11-1.11]; and double the odds of residential programme enrolment than those in the amphetamine use class (OR = 2.35; 95% CI = 1.50-3.68). No other class differences on mental health or QoL variables were found. Clients enrolled in day-programmes had higher odds of completing treatment.

CONCLUSIONS

There appear to be high levels of polysubstance use among young people entering substance use treatment in Australia. Wide-ranging polysubstance users were more likely to report psychotic symptoms and be enrolled into a residential programme than primary amphetamine users and alcohol and cannabis users.

Effects of a Residential Multimodal Psychological Treatment in an Addicted Population, at 6 and 12 Months: Differences Between Men and Women

The aim of this study is to explore the effects of a residential multimodal treatment intervention for an addict population. We gathered participants from the "Programa Base" (n = 166) of the Solidarity and Reinsertion Foundation of Murcia, and assessed the various problematic areas with the EuropASI at baseline level, 6 months and 12 months of treatment. We found improved outcomes in every area except for Legal Status. In addition, we found differences between male and female participants in their baseline evaluation, as well as between completers and non-completers. In conclusion, this data shows us some changes which occurred in individuals with problematic drug use during treatment, going further into the complex social reality which causes great suffering and damage to people and their families.

Does Treatment Readiness Shape Service-Design Preferences of Gay, Bisexual, and Other Men Who Have Sex with Men Who Use Crystal Methamphetamine? A Cross Sectional Study

Crystal methamphetamine (CM) disproportionately impacts gay, bisexual, and other men who have sex with men (gbMSM). However, not all gbMSM are interested in changing their substance use. The present study aimed to examine whether participant-preferred service characteristics were associated with their readiness to change. We surveyed gbMSM who used CM in the past six months, aged 18 plus years, on dating platforms. Participants rated service-design characteristics from “very unimportant” to “very important”. Multivariable regression tested service preference ratings across levels of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES-8D). Among 291 participants, 38.7% reported their CM use was not problematic, 19.5% were not ready to take any action to reduce or stop using CM, and 41.7% were ready to take action. On average, participants rated inclusive, culturally-appropriate, out-patient counselling-based interventions as most important. Participants with greater readiness-to-change scores rated characteristics higher than gbMSM with lesser readiness. Contingency management and non-abstinence programming were identified as characteristics that might engage those with lesser readiness. Services should account for differences in readiness-to-change. Programs that provide incentives and employ harm reduction principles are needed for individuals who may not be seeking to reduce or change their CM use.

Predictors of length of treatment, discharge reason, and re-admission to Aboriginal alcohol and other drug residential rehabilitation services in New South Wales, Australia

INTRODUCTION

Aboriginal clients accessing Aboriginal community-controlled residential alcohol and other drug rehabilitation services in New South Wales, Australia believe they have better outcomes due to culturally appropriate care. However, there is a paucity of published treatment outcome data. This study aims to identify predictors of treatment outcomes based on client characteristics at intake.

METHODS

A cross-sectional, retrospective, observational study of 2326 admissions to six services between January 2011 and December 2016. The outcomes were: (i) leaving treatment early; (ii) self-discharge or house discharge (by staff); and (iii) re-admission within two years. The predictors examined were Aboriginal status, age, justice system referral and primary substance of concern. Competing risk and Poisson regression analyses were used to identify trends in the data.

RESULTS

The mean age of clients was 33 years, and the majority (56%) stayed at least 6 weeks. Aboriginal clients whose primary substance of concern was stimulants were almost eight times more likely to re-admitted within 2 years than other clients (risk ratio 7.91; P < 0.001). Aboriginal clients who were also referred from justice were more likely to self-discharge (risk ratio 1.87; P < 0.001). Furthermore, Aboriginal clients who were aged older than 30 were less likely to have a re-admission (risk ratio 0.32; P ≤ 0.001).

DISCUSSION AND CONCLUSIONS

This study showed client characteristics that are predictive of harmful outcomes include age under 30, justice client, primary substance of use and their interactions. Future research could build on these results to aid ongoing development of residential rehabilitation programs for Aboriginal peoples.

Levels of Impulsivity, Hyperactivity, and Inattention and the Association with Mental Health and Substance Use Severity in Opioid-Dependent Patients Seeking Treatment with Extended-Release Naltrexone

The level of impulsivity, hyperactivity, and inattention (IHI) is higher among patients with substance use disorder (SUD) than in the general population. However, the prevalence of such symptoms in patients seeking treatment with an opioid antagonist, such as extended-release naltrexone (XR-NTX), is unknown. We screened 162 patients with opioid use disorder (OUD) seeking treatment with XR-NTX in Norway using the Adult ADHD Self-Report Scale (ASRS) to estimate the prevalence of IHI alongside an assessment of mental and physical health and substance use. Sixty-six patients scored above the clinical cut-off on the ASRS. Higher levels of IHI were significantly associated with a longer history of frequent amphetamine use, current alcohol use, and greater mental distress. Mental distress was the strongest factor associated with higher levels of IHI. The introduction of screening for IHI and mental distress in opioid maintenance treatment and XR-NTX would likely improve the quality of care and enable clinicians to tailor interventions to the needs of patients with high levels of IHI to prevent treatment discontinuation.

Dialectical behaviour therapy skills training for individuals with substance use disorder: A systematic review

ISSUES

Dialectical behaviour therapy skills training (DBT-ST) is currently being implemented as a standalone intervention for substance use disorders (SUD), despite limited empirical evidence to support its efficacy in this context. This review aimed to investigate the feasibility, acceptability and efficacy of DBT-ST for SUD.

APPROACH

English language journal articles which focused on quantitative evaluations of DBT-ST for SUD were identified by systematically searching five databases; Medline, Psychinfo, Pubmed, The Applied Social Sciences Index and Abstracts and Cumulative Index of Nursing and Allied Health Literature. Relevant grey literature was also identified using Google Scholar. The titles, abstracts and full-text of retrieved articles were independently screened by both authors. The nine retained articles were read in-depth and quality assessed by both authors. Data were synthesised narratively.

KEY FINDINGS

Interventions described as DBT-ST for SUD were implemented and adapted differently across studies. Despite these inconsistencies, DBT-ST was generally found to be acceptable and feasible for people with SUD. Findings offered preliminary support for DBT-ST for substance use reduction and emotion regulation enhancement for this cohort. Findings must be considered in light of the quality of studies which ranged from weak to strong.

IMPLICATIONS

Positive outcomes indicate that more rigorous studies, including large randomised controlled trials comparing DBT-ST to other evidence-based interventions for SUDs, are warranted.

CONCLUSIONS

Despite offering preliminary support for DBT-ST for SUD, the lack of controls, small samples and inconsistent adaptations of DBT-ST across studies, limits capacity to draw causal conclusions or make specific recommendations.

Correlates related to follow-up in a community engagement program in North Central Florida

AIMS

This analysis identifies the correlates of 60- and 120-day telephone-based study follow-ups among community-dwelling adults in North Central Florida.

METHODS

Six thousand three hundred and forty participants were recruited by Community Health Workers from the University of Florida's community engagement program with a face-to-face baseline and two phone follow-ups assessing indicators of health.

RESULTS

Physical disability versus none (adjusted odds ratio [aOR], 1.5; 95% confidence interval [CI], 1.2─1.9), high trust in research versus none (aOR, 1.5; 95% CI, 1.1─2.1), history of research participation versus none (aOR, 1.6; 95% CI, 1.3─2.0), having health insurance versus none (aOR, 1.4; 95% CI, 1.1─1.7), interest in research participation versus none (aOR, 1.8; 95% CI, 1.3─2.7), and no drug use versus drug use (aOR, 0.5; 95% CI, 0.3─0.9) significantly predicted completion of follow-up.

CONCLUSIONS

Health and social factors such as disability, insurance, history of and interest in research, trust and no drug use significantly predicted completing two follow-ups. These findings can facilitate efforts to minimize attrition in the research enterprise.

Longitudinal Substance Use and Biopsychosocial Outcomes Following Therapeutic Community Treatment for Substance Dependence

The Therapeutic Community (TC) model is considered an effective treatment for substance dependence, particularly for individuals with complex presentations. While a popular approach for this cohort across a number of countries, few studies have focussed on biopsychosocial and longer-term outcomes for this treatment modality. This study reports on substance use, dependence, and biopsychosocial outcomes up to 9 months post-exit from two TC sites.

METHODS

A longitudinal cohort study (n = 166) with two follow-up time points. Measures included substance use, dependence, subjective well-being, social functioning, and mental and physical health. Generalized Linear Models were employed to assess change over time.

RESULTS

At 9 months, 68% of participants reported complete 90-day drug abstinence. Alcohol frequency and quantity were reduced by over 50% at 9 months, with 32% of the sample recording 90-day abstinence at 9 months. Both alcohol and drug dependence scores were reduced by over 60%, and small to medium effect sizes were found for a range of psychosocial outcomes at 9 months follow-up, including a doubling of wellbeing scores, and a halving of psychiatric severity scores. Residents who remained in the TC for at least 9 months reported substantially better outcomes.

CONCLUSIONS

With notably high study follow-up rates (over 90% at 9 months post-exit), these data demonstrate the value of the TC model in achieving substantial and sustained improvements in substance use and psychosocial outcomes for a cohort with severe substance dependence and complex presentations. Implications for optimal length of stay are discussed.

Operationalising the quality of life construct in studies of alcohol and drug residential rehabilitation programme clients: A systematic review

INTRODUCTION AND AIMS

Quality of life (QOL) is increasingly recognised as an important treatment indicator in the alcohol and other drug (AOD) sector, particularly in treatment modalities providing 'whole of life programmes', such as residential rehabilitation. However, it is currently unclear how studies conducted in AOD residential rehabilitation settings have operationally defined and measured QOL. This study therefore aimed to determine current practices in defining and measuring the QOL of residential rehabilitation clients.

DESIGN AND METHODS

A systematic review of studies examining the QOL of AOD residential rehabilitation clients was conducted. Potential studies published in English between 1990 and 2018 were identified through a search of electronic databases (e.g. PsycINFO and PubMed), search engines (Google Scholar) and article reference lists.

RESULTS

The search identified a total of 1267 records, of which 16 met the inclusion criteria. Less than half of the included studies provided an operational definition of QOL. QOL was generally understood to be a subjective, multidimensional, client assessment construct. Twelve different instruments were used to assess QOL, of which two enabled clients to identify QOL dimensions important to themselves.

DISCUSSION AND CONCLUSIONS

QOL has been inconsistently measured in studies of AOD residential rehabilitation clients. As a result, the comparability and validity of research in this field may be weakened. There is a need to develop a consensual operational definition of QOL, including a core set of domains relevant to and endorsed by residential rehabilitation clients. Appropriate tools to measure client QOL need to be identified and disseminated.

The Value of Outdoor Behavioral Healthcare for Adolescent Substance Users with Comorbid Conditions

The damage inflicted on our society by mental health and substance use issues is reaching epidemic proportions with few signs of abating. One new and innovative strategy for addressing these comorbid issues has been the development of outdoor behavioral healthcare (OBH). This study compared the effectiveness of three post-acute adolescent substance use situations: OBH, treatment as usual (TAU), and no structured treatment (NST). The simulated target population was 13-17 years old with comorbid substance use and mental health issues. When costs were adjusted for actual completion rates of 94% in OBH, 37% in TAU, and $0 for NST, the actual treatment costs per person were $27 426 for OBH and $31 113 for TAU. OBH also had a cost-benefit ratio of 60.4% higher than TAU, an increased Quality in Life Years (QALY) life span, societal benefits of an additional $36 100, and 424% better treatment outcomes as measured by the Youth Outcome Questionnaire (YOQ) research instrument.

The effectiveness of residential treatment services for individuals with substance use disorders: A systematic review

BACKGROUND

Residential treatment is a standard treatment for individuals with severe and complex substance use problems. However, there is limited evidence on best practice approaches to treatment in these settings. This review provides a comprehensive update on the evidence base for residential treatment, and directions for future research and clinical practice.

METHOD

A systematic review of all studies published between January 2013 and December 2018 was conducted. Public health and psychology databases (Medline, CINAHL, PsycARTICLES and PsycINFO) were systematically searched, and forward and backward snowballing were used to identify additional studies. Studies were included if they were quantitative, assessed the effectiveness of residential substance treatment programs for adults, were published in the English language and in peer-reviewed journals. The Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies was used to assess methodological quality.

RESULTS

Our search identified 23 studies. Eight were rated as methodologically strong, five as moderate and ten rated as weak. Quality ratings were impacted by attrition at follow-up and research design. Despite limitations, results provide moderate quality evidence for the effectiveness of residential treatment in improving outcomes across a number of substance use and life domains.

CONCLUSION

With caution, results suggest that best practice rehabilitation treatment integrates mental health treatment and provides continuity of care post-discharge. Future research and practice should focus on better collection of outcome data and conducting data linkage of key health, welfare and justice agency administrative data to enhance understanding of risk and recovery trajectories.

An evaluation of the maintenance to abstinence (MTA) program in achieving abstinence in opioid users and improving mental health and quality of life

BACKGROUND

Residential opioid rehabilitation aims to improve the mental health and quality of life of opioid users through abstinence and residential program participation. This study aimed to determine the depression, anxiety, stress and quality of life amongst maintenance to abstinence (MTA) program residents. Secondary study aims were to assess the personal characteristics of MTA clients, addiction and risk taking behaviours, factors associated with program completion, as well as to assess the reliable change in participants' mental health and quality of life on exit.

METHODS

Retrospective analysis of routinely collected data (2013-2017) from surveys completed by 100 clients. Outcome measures were: Depression, Anxiety, Stress Score (DASS-42), World Health Organisation Quality of Life 8 questions (WHOQOL-8) and Kessler Psychological Distress Scale (K10). Other variables included demographics, drug use, other addictions, aggression, self-harm, suicidal ideation/attempts, and risk taking behaviours. Statistical methods included Chi-square, Fisher's exact, t-tests, repeated measures analysis of variance and the Reliable Change Index.

RESULTS

All mean DASS-42, WHOQOL-8 and K10 scores improved significantly in all participants from entry to exit (p < 0.001). The majority of participants demonstrated reliable improvement across all psychometric measures. Completion rates for the MTA program were 51%. Depression (p = 0.023), anxiety (p = 0.010) and stress (p = 0.015) DASS-42 scores decreased significantly more in completers compared to non-completers. The rate of improvement in mean WHOQOL-8 scores and psychological distress scores (K10) was not statistically significantly different between completers and non-completers over time. There was no significant difference between completers and non-completers on socio-demographics, self-reported drug addiction or risk taking behaviour on program entry, except for suicidal thoughts while intoxicated (p = 0.033). Completers were more satisfied with their relationships (p = 0.044) and living place (p = 0.040) on program entry.

CONCLUSION

Overall, completers and non-completers demonstrated improved mental health and quality of life from entry to exit, regardless of program completion. Depression, anxiety and stress reduced more markedly in program completers. Policy makers and programmers could use these findings to further validate their own programs to improve mental health and quality of life of opioid users.
