Effect of Case Management Interventions for Patients with Substance Use Disorders: A Systematic Review

Predictors of alcohol and other drug treatment completion among young people accessing residential and community-based treatment: A retrospective analysis of routinely collected service data

BACKGROUND AND AIMS

Young people accessing alcohol and other drug (AOD) treatment experience high rates of treatment disengagement, contributing to poorer outcomes. To improve outcomes, it is important to identify factors associated with treatment retention. This study measured the relationships between client characteristics, treatment characteristics, clinical severity measures and completion of treatment among young people.

DESIGN, SETTING AND PARTICIPANTS

This study was a retrospective analysis of routinely collected data set in residential- and community-based AOD services in New South Wales, Australia. Routinely collected data from the Network of Alcohol and Other Drug Agencies' (NADA) database were used. Included individuals were aged 10-24 years and accessed treatment between 2012 and 2023 (n = 17 474).

MEASUREMENTS

Variables included client-related characteristics, service characteristics and baseline measures of clinical severity [Kessler-10 (K10), EUROHIS-QoL, severity of dependence scale (SDS)]. Multivariable binary logistic regression models assessed the relationships between these characteristics and treatment completion.

FINDINGS

Rates of treatment completion were highest among adolescents in community-based treatment (57%) and lowest among young adults in residential treatment (35%). Polysubstance use was negatively associated with treatment completion among adolescents [adjusted odds ratio (adjOR) = 0.71, P < 0.001] and adults (adjOR = 0.70, P < 0.001) in community-based treatment, and adolescents in residential treatment (adjOR = 0.62, P = 0.006), as was housing insecurity (adolescents in community treatment, adjOR = 0.61, P = 0.001; adults in community treatment, adjOR = 0.77, P = 0.002; adolescents in residential treatment, adjOR = 0.42, P = 0.005). Attending youth-specific services was associated with higher treatment completion rates among adults in community-based (adjOR = 1.81, P < 0.001) and residential treatment (adjOR = 1.72, P < 0.001). Varying correlates of treatment completion were identified throughout treatment groups, reflecting the differences in population and/or needs across contexts.

CONCLUSIONS

In New South Wales, Australia, fewer than half of young people accessing alcohol and other drug treatment between 2012 and 2023 completed treatment, and completion rates were lower among those facing barriers such as polysubstance use and housing insecurity.

A 13-item Health of the Nation Outcome Scale (HoNOS-13): validation by item response theory (IRT) in patients with substance use disorder

BACKGROUND

The Health of the Nation Outcome Scale (HoNOS) is a widely used 12-item tool to assess mental health and social functioning. The French version has an added 13th item measuring adherence to psychotropic medication. The aim of the current study is to uncover the unknown pattern of the new item 13 and to compare the unidimensional and multidimensional fit of the new HoNOS-13 using Item Response Theory (IRT). This research question was studied among inpatients with substance use disorder (SUD).

METHODS

Six hundred and nine valid questionnaires of HoNOS-13 were analyzed using unidimensional (one-factor) and multidimensional (two-factor) IRT modeling.

RESULTS

The multidimensional model suggesting a first factor capturing psychiatric/impairment-related issues and a second factor reflecting social-related issues yielded better goodness-of-fit values compared to the unidimensional solution. This resulted in an improvement of all slope parameters which in turn translates to better discriminative power. Significant improvement in item location parameters were observed as well. The new item 13 had a good discriminative power (1.17) and covered a wide range of the latent trait (- 0.14 to 2.64).

CONCLUSIONS

We were able to validate the 13-item questionnaire including medication compliance and suggest that the HoNOS-13 can be recommended as a clinical evaluation tool to assess the problems and treatment needs for inpatients with SUD. Interestingly, the majority of item response categories are endorsed by respondents who are below and above the average levels of HoNOS. This indicates that the scale is able to discriminate between participants both at the low and at the high ends of the latent trait continuum. More importantly, the new item 13 has a good discriminative power and covers a broad range of the latent trait below and above the mean. It therefore has the desired profile of a good item and is a useful measure for the assessment of mental health and social functioning. Trial registration ClinicalTrials.gov, Identifier: NCT03551301.

Effectiveness of Brief In-person and Virtual Substance Use Disorder Counselor Trainings, 2019-2021

OBJECTIVES

Paraprofessional substance use disorder counselors (SUDCs) are an important component of expanding access to substance use disorder treatment, but little research on SUDC training currently exists. We evaluated knowledge and self-efficacy gain from brief in-person and virtual workshops for paraprofessional SUDC student-trainees.

METHODS

Student-trainees (N = 100) enrolled in an undergraduate SUDC training program completed 6 brief workshops from April 2019 to April 2021. Three in-person workshops during 2019 covered clinical assessment, suicide risk and evaluation, and motivational interviewing, and 3 virtual workshops during 2020-2021 covered family engagement and mindfulness-oriented recovery enhancement, as well as screening, brief intervention, and referral to treatment for expectant mothers. Pretest and posttest online surveys measured student-trainee knowledge gain related to all 6 SUDC modalities. Results of paired sample t tests evaluated changes in knowledge and self-efficacy from pretest to posttest.

RESULTS

All 6 workshops showed a significant gain in knowledge from pretest to posttest. Four workshops showed a significant gain in self-efficacy from pretest to posttest. Hedges g ranged from 0.70 to 1.95 for knowledge gain and from 0.61 to 1.73 for self-efficacy gain across workshops. Common language effect sizes indicating the probability that a participant increased one's score from pretest to posttest ranged from 76% to 93% for knowledge gain and from 73% to 97% for self-efficacy gain across workshops.

CONCLUSIONS

Results of this study add to the limited research base on training for paraprofessional SUDCs and suggest that in-person learning and virtual learning are both viable brief training tools for students.

First Responder Assertive Linkage Programs: A Scoping Review of Interventions to Improve Linkage to Care for People Who Use Drugs

CONTEXT

In response to the drug overdose crisis, first responders, in partnership with public health, provide new pathways to substance use disorder (SUD) treatment and other services for individuals they encounter in their day-to-day work.

OBJECTIVE

This scoping review synthesizes available evidence on first responder programs that take an assertive approach to making linkages to care.

RESULTS

Seven databases were searched for studies published in English in peer-reviewed journals between January 2000 and December 2019. Additional articles were identified through reference-checking and subject matter experts. Studies were selected for inclusion if they sufficiently described interventions that (1) focus on adults who use drugs; (2) are in the United States; (3) involve police, fire, or emergency medical services; and (4) assertively link individuals to SUD treatment. Twenty-two studies met inclusion criteria and described 34 unique programs, implementation barriers and facilitators, assertive linkage strategies, and linkage outcomes, including unintended consequences.

CONCLUSIONS

Findings highlight the range of linkage strategies concurrently implemented and areas for improving practice and research, such as the need for more linkages to evidence-based strategies, namely, medications for opioid use disorder, harm reduction, and wraparound services.

Acute Care Utilization After Recovery Coaching Linkage During Substance-Related Inpatient Admission: Results of Two Randomized Controlled Trials

BACKGROUND

For patients with substance use disorder (SUD), a peer recovery coach (PRC) intervention increases engagement in recovery services; effective support services interventions have occasionally demonstrated cost savings through decreased acute care utilization.

OBJECTIVE

Examine effect of PRCs on acute care utilization.

DESIGN

Combined results of 2 parallel 1:1 randomized controlled trials.

PARTICIPANTS

Inpatient adults with substance use disorder INTERVENTIONS: Inpatient PRC linkage and follow-up contact for 6 months vs usual care (providing contact information for SUD resources and PRCs) MAIN MEASURES: Acute care encounters (emergency and inpatient) 6 months before and after enrollment; encounter type by primary diagnosis code category (mental/behavioral vs medical); 30-day readmissions with Lace+ readmission risk scores.

KEY RESULTS

A total of 193 patients were randomized: 95 PRC; 98 control. In the PRC intervention, 66 patients had a pre-enrollment acute care encounter and 56 had an encounter post-enrollment, compared to the control group with 59 pre- and 62 post-enrollment (odds ratio [OR] = -0.79, P = 0.11); there was no significant effect for sub-groups by encounter location (emergency vs inpatient). There was a significant decrease in mental/behavioral ED visits (PRC: pre-enrollment 17 vs post-enrollment 10; control: pre-enrollment 13 vs post-enrollment 16 (OR = -2.62, P = 0.02)) but not mental/behavioral inpatient encounters or medical emergency or inpatient encounters. There was no significant difference in 30-day readmissions corrected for Lace+ scores (15.8% PRC vs 17.3% control, OR = 0.19, P = 0.65).

CONCLUSIONS

PRCs did not decrease overall acute care utilization but may decrease emergency encounters related to substance use.

Substance Use Disorders in Global Mental Health Delivery: Epidemiology, Treatment Gap, and Implementation of Evidence-Based Treatments

LEARNING OBJECTIVES

After participating in this activity, learners should be better able to:• Assess the treatment gap for patients with substance use disorders• Evaluate treatments and models of implementation for substance use disorders ABSTRACT: Substance use disorders (SUDs) account for substantial global morbidity, mortality, and financial and social burden, yet the majority of those suffering with SUDs in both low- and middle-income (LMICs) and high-income countries (HICs) never receive SUD treatment. Evidence-based SUD treatments are available, but access to treatment is severely limited. Stigma and legal discrimination against persons with SUDs continue to hinder public understanding of SUDs as treatable health conditions, and to impede global health efforts to improve treatment access and to reduce SUD prevalence and costs. Implementing SUD treatment in LMICs and HICs requires developing workforce capacity for treatment delivery. Capacity building is optimized when clinical expertise is partnered with regional community stakeholders and government in the context of a unified strategy to expand SUD treatment services. Workforce expansion for SUD treatment delivery harnesses community stakeholders to participate actively as family and peer supports, and as trained lay health workers. Longitudinal supervision of the workforce and appropriate incentives for service are required components of a sustainable, community-based model for SUD treatment. Implementation would benefit from research investigating the most effective and culturally adaptable models that can be delivered in diverse settings.

Homelessness, crack use, and length of stay as predictors of planned discharge from night care in a Psychosocial Care Center

Objective: identify predictors of planned discharge to night care embracement in a Psychosocial Care Center Alcohol and Drugs (CAPS AD III). Methods: Quantitative, retrospective, and documentary study of 560 medical records of people with problems resulting from the use of alcohol and other drugs who were admitted to the hospital at night in a CAPS AD III in São Paulo, over five years. As a dependent variable, the type of discharge was used (planned or not). As independent variables, the profile of the subjects related to substance use and time in hospital. Results: 1,097 admissions were identified with 50.4% of unplanned discharge associated with homelessness (p = 0.007), problematic use crack (p = 0.015), length of reception proposed by the team (p = 0.029) and length of stay of the user (p < 0.001). Conclusion: Being homeless, problematic use of crack, and lack of user participation on the decisions regarding length of stay in CAPS AD III were associated with unplanned discharge.

Engaging vulnerable populations in drug treatment court: Six month outcomes from a co-occurring disorder wraparound intervention

OBJECTIVE

Although drug treatment courts (DTCs) have demonstrated positive outcomes, participants with co-occurring mental health and substance use disorders (CODs) are a high-risk group that often struggle with treatment engagement not previously examined. This pilot study fills this gap by looking at six-month behavioral health and criminal justice outcomes among a hard to engage DTC COD participant sample in two Massachusetts DTCs receiving a wraparound-treatment (Maintaining Independence and Sobriety through Systems Integration, Outreach, and Networking-Criminal Justice - MISSION-CJ).

METHODS

Participants were evaluated at baseline and at six-month follow-up. Bivariate analyses examined baseline differences between clients with higher versus low engagement were examined. A mixed analysis of variance (ANOVA) for repeated measures with time as the within subject factor, and level of engagement as the between subject factor was performed for criminal justice (CJ) and behavioral health outcomes.

RESULTS

Participants were primarily male (86.6%), White (90.6%), living in unstable housing (86.2%), had an average of 18.94 years of criminal justice involvement, had an average of 15.49 years of regular illicit substance use, and mild mental health symptoms as measured by the BASIS-32 average total score (0.51), with no statistically significant differences at baseline from bivariate analyses. Mixed ANOVA results demonstrated significant effect time of time in MISSION-CJ on reducing nights in jail (p = 0.0266), opioid use (p = 0.0013), and mental health symptom (p = 0.0349). Additional improvements in nights in jail p = 0.0139), illicit substance use (p = 0.0358), and opioid use (p = 0.0013), were observed for clients that had high engagement in MISSION-CJ.

CONCLUSIONS

Wraparound services, such as MISSION-CJ, alongside DTC programming for a chronic relapsing DTC population can improve engagement in treatment and CJ and behavioral health outcomes. Future research is needed with MISSION-CJ that includes a randomized trial and a larger sample.

The quality in psychiatric care-Addiction outpatient instrument: Psychometric properties and patient views of the quality of care

Aim

The aim of the study was to evaluate the psychometric properties and factor structure of the Quality in Psychiatric Care—Addiction Outpatient (QPC‐AOP) instrument and to describe the experiences with the quality of care among addiction outpatients.

Design

The study has a cross‐sectional design.

Methods

A sample of 244 patients with addiction and psychiatric disorders completed the QPC‐AOP.

Results

Confirmatory factor analysis showed adequate to excellent goodness‐of‐fit indices supporting the 9‐factor structure of the QPC‐AOP. The results thus demonstrate that the concept of quality of care to a large extent is equivalent among outpatients from general psychiatry and from outpatient addiction services. Internal consistency for the full QPC‐AOP was adequate, but poor for some of the separate factors. The patients’ ratings of quality of care were generally high; the highest rating was for Encounter and the lowest for Discharge.

Recovery opioid overdose team (ROOT) pilot program evaluation: A community-wide post-overdose response strategy

BACKGROUND

Effective interventions for overdose survivors are needed in the emergency departments (EDs). One promising model is the use of peer recovery coaches to engage with survivors in EDs, followed by partnering with community case management navigators to connect survivors to recovery support and treatment services. This paper describes the evaluation of a pilot program, the Recovery Opioid Overdose Team (ROOT), a warm hand-off system that links survivors to treatment services post-ED discharge. Methods: The ROOT program is composed of a peer recovery coach who is in long-term recovery, and a case management navigator who specializes in mental health care and provides guidance for accessing community services. After an overdose reversal, law enforcement contacts a county 24/7 Crisis Team, who then notifies ROOT. The peer recovery coach engages with the survivor in the ED, and then follow up continues with the case management navigator and the peer recovery coach for up to 90 days post-ED discharge. Retrospective chart reviews were conducted to evaluate ROOT in two Midwest EDs from September 2017 through March 2019. Results: Of the 122 referrals, 77.0% (n = 94) of the survivors initially engaged with ROOT in the ED or in the community. The remaining 23.0% (n = 28) left the ED against medical advice or were unengaged. The majority of overdose survivors were male (63.9%; n = 78), White (43.4%; n = 53), had housing (80.2%; n = 48), and access to transportation (48.4%; n = 59). From the 122 referrals, 33.6% (n = 41) received ongoing treatment services (n = 20 outpatient, n = 17 residential, n = 2 detoxification facility, n = 1 recovery housing, n = 1 medication treatment for opioid use disorder), 2.5% (n = 3) were incarcerated, 2.5% (n = 3) died, and 61.5% (n = 75) declined services. Conclusions: The ROOT, a community-wide coordinated program in the EDs, shows promise in linking overdose survivors to recovery support and treatment services post-overdose.

The Effects of Prolonged Exposure on Substance Use in Patients With Posttraumatic Stress Disorder and Substance Use Disorders

Despite research demonstrating the benefit of exposure-based therapy for posttraumatic stress disorder (PTSD) in patients with co-occurring substance use disorders, there remains a strong clinical expectation that this treatment will exacerbate substance use or other psychiatric symptoms. The present study evaluated within-session and session-to-session changes in (a) craving and use of substances for a range of drug classes and (b) symptoms of PTSD and other psychiatric distress in a sample of 44 SUD patients who received prolonged exposure (PE) therapy for PTSD. Visual analog scales showed no within-session increases in craving, except for cocaine, within Session 8. Across sessions, craving scores dropped for heroin, methadone, benzodiazepines, and cocaine; no increases in craving were found. Past-week substance use reported at each session did not differ. The severity of PTSD symptoms and self-reported serious emotional problems decreased from Session 1 to subsequent sessions, with no increases or decreases in other psychiatric, social, or medical problems. Finally, PTSD severity was unrelated to substance use reported 1 or 2 weeks later. Substance use during the past week was associated with higher PTSD severity scores at the next session, B = 6.86 (SE = 2.87), p = .018, but was not associated 2 weeks later. These findings indicate that the concern that exposure therapy for PTSD will increase SUD patients' substance use or other psychiatric symptoms may be unwarranted, and, thus, SUD patients, including those who are actively using, should have access to effective treatments for PTSD, like PE.

Systematic review and meta-analyses of randomized control trials of the effectiveness of psychosocial interventions for homeless adults

AIMS

To evaluate the effect of psychosocial interventions for homeless adults on their psychosocial outcomes.

DESIGN

A systematic review and meta-analyses were performed for critical appraisal and synthesis of the included studies.

DATA SOURCES

A systematic search of studies published before 10 September 2018 was performed using PubMed, Cochrane Library, EMBASE, PsycINFO, and CINAHL.

REVIEW METHODS

The review included randomized controlled trials conducting psychosocial interventions and assessing psychosocial outcomes for homeless adults. After systematically describing study and intervention characteristics, we conducted meta-analyses by the type of outcome and subgroup meta-analyses by the type of intervention and outcome. Fourteen studies were included in this review and 11 were included in the meta-analyses.

RESULTS

A significant effect of psychosocial interventions in reducing anxiety and enhancing mental health status among homeless adults was noted.

CONCLUSION

The meta-analyses showed that psychosocial interventions may reduce anxiety and enhance the mental health status of homeless people. Specifically, we suggest that relaxation response training may be effective in improving anxiety and mental health status and cognitive behavioural therapy may reduce anxiety.

IMPACT

Although psychosocial interventions for homeless persons have been implemented for a decade, their impact for psychosocial outcomes among homeless adults has not been evaluated. This review suggest that psychosocial interventions may improve anxiety and mental health status among homeless adults. The findings of the present study may provide directions for developing psychosocial interventions to help vulnerable homeless adults in managing psychological outcomes.

Change in psychosocial factors connected to coping after inpatient treatment for substance use disorder: a systematic review

BACKGROUND

Among the adult population worldwide, about 0.5% has illicit drug use disorder (DUD) and about 5% has alcohol use disorder (AUD). Dependency on alcohol, medication or illicit drugs are recognised as risk factors for disabling disease and early death. Treatment for substance use disorders (SUD) is important in promoting persistent abstinence and may be perceived as a valuable public health measure. The current systematic review aims at exploring how psychosocial factors connected to recovery capital and coping behaviour, change after inpatient SUD treatment.

METHODS

A systematic search was conducted in Campbell Collaboration Library, Cochrane Library, EMBASE, Epistemonikos, Medline, PsychINFO, Social Sciences Citation Index and SocINDEX. Cohort studies on psychosocial outcomes for adults who had attended to inpatient SUD treatment that exceeds 3 months, were included. The outcome of interest was change in psychosocial factors. The search results were identified as include, exclude or unclear by one author and then screened by the second author with a specific focus on studies recognised as unclear. Diverging evaluations of eligibility among the unclear studies were resolved by discussion. In case of disagreement, the third author decided the eligibility of the studies in question.

RESULTS

Findings imply an overall progress in mental health, and a potential improvement in employment status and perceived social support after inpatient SUD treatment. Additionally, findings indicate a decrease in substance use from admission to follow-up after discharge from inpatient SUD treatment. These findings are consistent with earlier research on important factors in recovering from SUD. Findings on change in self-efficacy, housing, education and Quality of Life (QoL) however, were scantly researched and were expected to be more prominent outcomes of interest among the included studies.

CONCLUSION

Due to the substantial resources used to provide SUD treatment, knowledge about recovery capital, like psychosocial factors that facilitate coping behaviour and reintegration to society, should be standardised and used by SUD treatment providers.

Psychosocial factors associated with coping behaviour after inpatient treatment for substance use disorder: a systematic review study protocol

INTRODUCTION

Much is known about factors associated with coping with abstinence from substance use. The planned systematic review aims to summarise available studies exploring the change in psychosocial factors associated with coping after long-term (≥3 months) inpatient treatment for substance use disorder (SUD). Examples of psychosocial factors of interest are social support, housing, activity (eg, employment and education) mental health and quality of life. Coping behaviour can be understood as responses or actions taken in a stressful situation, particularly how psychosocial factors affect a person's coping behaviour with abstinence from substances in everyday life (characterised as a stressful situation).

METHODS AND ANALYSIS

A set of text words were developed based on the population (people with SUD), exposure (long-term inpatient SUD treatment), outcome (psychosocial factors) and study design (prospective cohort studies) of interest. A systematic search will be conducted in eight electronic databases: Campbell Collaboration Library, Cochrane Library, EMBASE, Epistemonikos, Medline, PsychINFO, Social Sciences Citation Index and SocINDEX. The titles and abstracts will be screened for relevance before a pre-piloted data collection form will be used to evaluate eligibility and extract data from the search results. The planned review will include peer-reviewed study reports published in English or Scandinavian language.

ETHICS AND DISSEMINATION

The target group, people with SUD, might be considered as vulnerable. Based on this, the population will be the group of interest in the planned systematic review of studies that have already been conducted. Patients and the general public will not be involved in the development of this systematic review. The results will be summarised in a study report and submitted to a peer-reviewed international journal. Additionally, results will be disseminated in the mass media and at international research conferences.

A Meta-Analysis of the Efficacy of Case Management for Substance Use Disorders: A Recovery Perspective

Background: Case management is a client-centered approach to improve the coordination and continuity of service delivery, especially for persons with substance use disorders (SUD) and multiple and complex support needs. This intervention supports individuals by helping them identify needed services, facilitate linkage with services, and promote participation and retention in services. However, it is questionable whether case management is equally effective in promoting recovery and aspects of personal functioning. The objective was to conduct an updated meta-analysis and to assess whether case management was more effective than treatment as usual (TAU) among persons with SUD for improving treatment-related (e.g., successful linkage with and retention in treatment) as well as personal functioning outcomes (e.g., substance use). Methods: This meta-analysis focuses on randomized controlled trials (RCTs) that included persons with alcohol or drug use disorders and compared case management with TAU. To be eligible, interventions had to meet core case management functions as defined in the literature. We conducted searches of the following databases to May 2017: the Cochrane Drugs and Alcohol Specialized Register, CENTRAL, PubMed, Embase, CINAHL, and Web of Science. Also, reference lists of retrieved publications were scanned for relevant (un)published studies. Results: The overall effect size for case management compared to TAU across all outcome categories and moments was small and positive (SMD = 0.18, 95% CI 0.07-0.28), but statistically significant. Effects were considerably larger for treatment tasks (SMD = 0.33, 95% CI 0.18-0.48) than for personal functioning outcomes (SMD = 0.06, 95% CI -0.02 to 0.15). The largest effect sizes were found for retention in substance abuse treatment and linkage with substance abuse services. Moderator effects of case management models and conditions were assessed, but no significant differences were observed. Conclusions: The primary results from earlier meta-analyses were supported: case management is more effective than TAU conditions for improving outcomes, but this effect is significantly larger for treatment-related tasks than for personal functioning outcomes. Case management can be an important supplement to available services for improving linkage and retention, although further research is needed to assess its potential for supporting recovery from a longitudinal perspective.

Health care costs of case management for frequent users of the emergency department: Hospital and insurance perspectives

BACKGROUND

In most emergency departments (EDs), few patients account for a relatively high number of ED visits. To improve the management of these patients, the university hospital of Lausanne, Switzerland, implemented an interdisciplinary case management (CM) intervention. This study examined whether the CM intervention-compared with standard care (SC) in the ED-reduced costs generated by frequent ED users, not only from the hospital perspective, but also from the third-party payer perspective, that is, from a broader perspective that takes into account the costs of health care services used outside the hospital offering the intervention.

METHODS

In this randomized controlled trial, 250 frequent ED users (>5 visits during the previous 12 months) were allocated to either the CM or the SC group and followed up for 12 months. Cost data were obtained from the hospital's analytical accounting system for the entire sample and from health insurance companies for a subgroup (n = 140). Descriptive statistics and multivariate regressions were used to make comparisons between groups and assess the contribution of patient characteristics to the main cost components.

RESULTS

At the end of the 12-month follow-up, 115 patients were in the CM group and 115 in the SC group (20 had died). Despite differences in economic costs between patients in the CM intervention and the SC groups, our results do not show any statistically significant reduction in costs associated with the intervention, either for the hospital that housed the intervention or for the third-party payer. Frequent ED users were big users of health services provided by both the hospital and community-based services, with 40% of costs generated outside the hospital that housed the intervention. Higher age, Swiss citizenship, and having social difficulty increased costs significantly.

CONCLUSIONS

As the role of the CM team is to guide patients through the entire care process, the intervention location is not limited to the hospital but often extends into the community.

Effects of substance use disorder on treatment process and outcome in a ten-session psychiatric treatment for borderline personality disorder

BACKGROUND

Dual diagnosis is common in Borderline Personality Disorder (BPD), one of the most common being Substance Use Disorder (SUD). Previous studies have shown that general psychiatric management (GPM) was effective in reducing borderline symptoms. In the present study, we tested whether the short GPM was as effective in the BPD + SUD as in the BPD group.

METHODS

We analysed a group of 99 patients presenting a BPD. 51 of these patients presented a SUD. The BPD group and the BPD + SUD group received a manual-based short variant of the GPM treatment. Previous studies have shown that a 10-session version of GPM was effective in reducing borderline symptoms at the end of the treatment (Psychother Psychosom 83:176-86, 2014).

RESULTS

We found no significant difference in the reduction of general symptoms, which diminished in both groups. The specific borderline symptoms were also reduced in both groups, but there was a slightly higher reduction of the borderline symptoms in the SUD group. The therapeutic alliance progressed positively in all groups. Moreover, the alliance increased more over time in the SUD group.

CONCLUSION

The short variant of GPM seems to be effective in BPD treatment independently from the presence of SUD. Therefore, this treatment could be an effective entry-level treatment for patients with dual diagnosis as well as patients with BPD only. Further studies are needed to confirm efficacy and long-term outcome.
