Interventions to Improve Post-Detoxification Treatment Engagement and Alcohol Recovery: Systematic Review of Intervention Types and Effectiveness

Psychological and Clinical Parameters as Predictors of Relapse in Alcohol-Dependent Patients During and After Extensive Inpatient Rehabilitation Treatment

BACKGROUND

Psychological parameters related to alcohol dependence (AD) affect patients' behavioral and cognitive control, decision making, impulsivity and inhibitory control. People with AD often have a chronic course with a relapse to dependent substance use even after extensive treatment. This study investigated whether the psychological parameters of patients with AD predict (a) premature termination of treatment, and/or (b) relapse into consumption of alcohol from admission until 6 weeks after discharge from an inpatient rehabilitation treatment.

METHODS

Participants: Alcohol-dependent patients consecutively admitted for a duration of about three months to inpatient rehabilitation treatment in a hospital specialized in substance use disorders. Craving (OCDS-G) and impulsivity (BIS-11; UPPS) were assessed with computerized questionnaires. Attentional bias and inhibitory control were measured with two computer-based experiments (dot-probe task; stop-signal task (SST)). Investigations were conducted at entry (T1); after 6 weeks (T2); and during the last two weeks of the inpatient treatment (T3). Some N = 128 patients finished the first, N = 102 the second and N = 83 the third assessments. Outcome variables were discontinuation of treatment and abstinence or relapse until follow-up 6 weeks after discharge; participants were contacted via telephone.

RESULTS

None of the variables are associated with discontinuation of treatment. Poor inhibitory control (SST) and high craving (OCDS-5) levels, measured at T1, are significantly associated with relapse. Higher impulsivity (UPPS) measured at T2 and T3 is significantly associated with relapse. Exploratory analyses showed that older age, longer inpatient treatment duration and time spent in abstinence before rehabilitation treatment were significantly associated with a reduced risk of relapse.

CONCLUSIONS

Psychological parameters, craving and impulsivity levels did not predict relapse to a high degree. It is assumed that discontinuation of treatment and relapse may be associated with different issues, such as social context, and individual motivation levels. In contrast, the length of both abstinence before admission and of inpatient treatment were significantly associated with abstinence; it is here suggested that recovery time duration may be an underestimated influencing factor regarding relapse in AD patients.

A Scoping Review of Suicide Prevention Interventions for Lesbian, Gay, Bisexual, Transgender, Queer, and Other Sexual and Gender Minority Individuals

Purpose: This scoping review summarizes the literature on suicide-specific psychological interventions among lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) people to synthesize existing findings and support future intervention research and dissemination. Methods: Electronic databases PsycInfo and PubMed were searched for reports of psychological intervention studies with suicide-related outcome data among LGBTQ+ people. A total of 1269 articles were screened, and 19 studies met inclusion criteria (k = 3 examined suicide-specific interventions tailored to LGBTQ+ people, k = 4 examined nontailored suicide-specific interventions, k = 11 examined minority stress- or LGBTQ+ interventions that were not suicide-specific, and k = 1 examined other types of interventions). Results: Synthesis of this literature was made challenging by varied study designs, and features limit confidence in the degree of internal and external validity of the interventions evaluated. The only established suicide-specific intervention examined was Dialectical Behavior Therapy, and minority stress- and LGBTQ-specific interventions rarely targeted suicidal thoughts and behaviors (STBs). Nevertheless, most interventions reviewed demonstrated support for feasibility and/or acceptability. Only five studies tested suicide-related outcome differences between an LGBTQ+ group and a cisgender/heterosexual group. These studies did not find significant differences in STBs, but certain subgroups such as bisexual individuals may exhibit specific treatment disparities. Conclusion: Given the dearth of research, more research examining interventions that may reduce STBs among LGBTQ+ people is critically needed to address this public health issue.

Medications for alcohol-use disorder and follow-up after hospitalization for alcohol withdrawal: A multicenter study

BACKGROUND

Alcohol withdrawal is a common reason for admission to acute care hospitals. Prescription of medications for alcohol-use disorder (AUD) and close outpatient follow-up are commonly recommended, but few studies report their effects on postdischarge outcomes.

OBJECTIVES

The objective of this study is to evaluate the effects of medications for AUD and follow-up appointments on readmission and abstinence.

METHODS

This retrospective cohort study evaluated veterans admitted for alcohol withdrawal to medical services at 19 Veteran Health Administration hospitals between October 1, 2018 and September 30, 2019. Factors associated with all-cause 30-day readmission and 6-month abstinence were examined using logistic regression.

RESULTS

Of the 594 patients included in this study, 296 (50.7%) were prescribed medications for AUD at discharge and 459 (78.5%) were discharged with follow-up appointments, including 251 (42.8%) with a substance-use clinic appointment, 191 (32.9%) with a substance-use program appointment, and 73 (12.5%) discharged to a residential program. All-cause 30-day readmission occurred for 150 patients (25.5%) and 103 (17.8%) remained abstinent at 6 months. Medications for AUD and outpatient discharge appointments were not associated with readmission or abstinence. Discharge to residential treatment program was associated with reduced 30-day readmission (adjusted odds ratio [AOR]: 0.39, 95% confidence interval [95% CI]: 0.18-0.82) and improved abstinence (AOR: 2.50, 95% CI: 1.33-4.73).

CONCLUSIONS

Readmission and return to heavy drinking are common for patients discharged for alcohol withdrawal. Medications for AUD were not associated with improved outcomes. The only intervention at the time of discharge that improved outcomes was discharge to residential treatment program, which was associated with decreased readmission and improved abstinence.

Neuropsychological Abnormalities Associated with Alcohol Dependence During Long-Term Rehabilitation Treatment of German Inpatients

BACKGROUND

Alcohol dependence is associated with several neuropsychological abnormalities, such as increased impulsivity or attentional bias towards drug-related stimuli. However, it is debated whether these abnormalities are on the decline after long-term abstinence from alcohol. Inpatient rehabilitation treatment enables the longitudinal investigation of such variables during a long, largely secured, period of abstinence.

METHODS

This study involved alcohol-dependent patients consecutively admitted for a duration of 14-26 weeks to an inpatient rehabilitation treatment center located in a hospital specializing in substance use disorders. Craving and impulsivity were assessed with the means of two questionnaires (e.g., OCDS-G and BIS-11); conversely, attentional bias and problems with inhibition were measured with the help of two computer-based experiments (e.g., dot-probe task and stop-signal-reaction task). Investigations were conducted at entry, after 6 weeks, and during the last two weeks of the inpatient treatment.

RESULTS

A total of 130 patients with alcohol dependence (mean age 43.3 years; 78.5% male) completed the first, N = 102 the second, and N = 83 the final assessment. Over the whole period of inpatient treatment, there was a significant decrease in patients' scores for both craving (t(83) = 7.8, p < 0.001) and impulsivity (t(82) = -3.75, p < 0.001, t(82) = 4.4, p < 0.001). However, there were no significant changes regarding attentional bias (t(82) = 0.16, p = 0.494) and inhibitory control (t(76) = 0.04, p = 0.482) scores.

CONCLUSIONS

Neuropsychological abnormalities associated with alcohol dependence might persist even after a long abstinence period. The decrease in both craving and impulsivity levels may be explained by the protected, alcohol-free, hospital environment; however, patients' risk of post-discharge relapse may remain high, as the basic neurobiological mechanisms of alcohol dependence may persist for long periods, and possibly for more than 3-6 months.

Goals and Reasons for Entering Inpatient Withdrawal Treatment, and Perceptions of Help Received

OBJECTIVE

Abstinence has been the primary treatment goal for alcohol and other drug (AOD) users attending withdrawal treatment. However, other outcomes including harm reduction have also been identified. This observational study aimed to describe participants' goals and reasons for seeking inpatient withdrawal treatment and compare the needs of clients with comorbid mental health problems and those without.

METHODS

Participants completed questionnaires at intake and discharge. Questionnaires assessed reasons for entering withdrawal treatment, goals, comorbidity, and perceived help received.

RESULTS

The sample comprised 1746 participants (69.4% male). Participants endorsed diverse reasons for entering withdrawal treatment. The most and least endorsed reasons were "stop using" (97.9%) and "legal reasons" (43.1%). Comorbidity groups varied significantly in their endorsement of reasons for mental health, physical health, harm reduction, financial, and legal.

CONCLUSION

AOD users enter withdrawal treatment with a variety of reasons and goals including harm reduction. Variations in rates of endorsement highlight the importance of identifying individual needs dependent on mental health comorbidity.

Motives for substance use and 6-month substance use outcomes among detoxification patients with a history of physical or sexual abuse or posttraumatic stress disorder

Trauma-exposed individuals with a history of physical or sexual abuse or documented posttraumatic stress disorder (PTSD) diagnosis may use substances to address trauma-related symptoms. However, the motives for using substances among adults with a trauma history or PTSD are unclear despite their informative role in treatment planning. Additionally, trauma is associated with poorer substance use outcomes, although this has not been examined among detoxification patients. The current study examined motives for substance use at baseline and substance use outcomes during 6 months postbaseline among 298 veteran detoxification patients (i.e., alcohol, opioids, or both) with and without (a) a history of physical or sexual abuse and (b) a PTSD diagnosis. At baseline, participants with a physical or sexual abuse history were more likely to report the use of substances to temporarily lower stress, forget problems, and avoid uncomfortable feelings than those without this history, ds = 0.25-0.40. Compared with participants without a PTSD diagnosis, participants with diagnosed PTSD were more likely to report using substances to temporarily lower stress, d = 0.25. Longitudinal analyses demonstrated that the baseline characteristics of physical abuse history, sexual abuse history, and diagnosed PTSD were all associated with higher scores on a measure of risk factors for relapse (e.g., cravings, family/social problems) as assessed during the postdetoxification period, φ = .13, .10, and .09, respectively. Detoxification patients with physical and/or sexual abuse histories or PTSD diagnoses may need treatments that better address trauma symptoms to help them sustain abstinence.

Innovating for real-world care: A systematic review of interventions to improve post-detoxification outcomes for opioid use disorder

BACKGROUND

Inpatient detoxification is a common health care entry point for people with Opioid Use Disorder (OUD). However, many patients return to opioid use after discharge and also do not access OUD treatment. This systematic review reports on the features and findings of research on interventions developed specifically to improve substance use outcomes and treatment linkage after inpatient detoxification for OUD.

METHODS

Of 6419 articles, 64 met inclusion criteria for the current review. Articles were coded on key domains including sample characteristics, study methods and outcome measures, bias indicators, intervention type, and findings.

RESULTS

Many studies did not report sample characteristics, including demographics and co-occurring psychiatric and substance use disorders, which may impact postdetoxification OUD treatment outcomes and the generalizability of interventions. Slightly more than half of studies examined interventions that were primarily medical in nature, though only a third focused on initiating medication treatment beyond detoxification. Medical and combination interventions that focused on initiating medications for OUD generally performed well, as did psychological interventions with one or more reinforcement-based components.

CONCLUSIONS

Research efforts to improve post-detoxification outcomes would benefit from clearer reporting of sample characteristics that are associated with treatment and recovery outcomes, including diagnostic comorbidities. Findings also support the need to identify ways to introduce medication for opioid use disorder (MOUD) and other effective treatments including reinforcement-based interventions during detoxification or soon after.

Changes in substance use during outpatient treatment for substance use disorders: a prospective Norwegian cohort study from 2016 to 2020

Background

Continuous use of amphetamines, alcohol, benzodiazepines, cannabis, cocaine, or opioids contributes to health impairments, increased morbidity, and overdose deaths among patients with substance use disorders (SUDs). This study evaluates the impact of inpatient detoxification, injecting substance use, age, and gender on substance use over time among patients undergoing outpatient SUD treatment.

Methods

We used data from a cohort of SUD patients in Norway obtained from health assessments of self-reported substance use and sociodemographic and clinical factors. A total of 881 substance use measurements, including substances and frequency of use, were assessed for 708 SUD patients in 2016–2020. Of those, 171 patients provided two or more substance use measurements. The total substance use was calculated, creating a substance use severity index (SUSI), ranging from zero (no use) to one (daily use of all substances). We defined baseline as the first substance use measurement when the measurements were listed chronologically. Time was defined as years from baseline. We used a linear mixed model to analyze the SUSI at baseline and over time, and its associations with inpatient detoxification, injecting substance use, gender, and age, presented with coefficients and 95% confidence intervals (CI).

Results

No longitudinal changes in the SUSI were found compared with baseline (change in SUSI (cSUSI): 0.04, 95% CI: − 0.05;0.13, p = 0.397). Likewise, “inpatient detoxification” was not associated with changes in the SUSI compared with “no inpatient detoxification” (cSUSI: 0.00, 95% CI: − 0.04;0.04, p = 0.952). However, injecting substances were associated with a higher SUSI than not injecting substances at baseline (difference in SUSI: 0.19, 95% CI: 0.16;0.21, p = < 0.001), and starting to inject substances was associated with increasing SUSI over time compared with not starting to inject substances (cSUSI: 0.11, 95% CI: 0.07;0.15, p = < 0.001). Gender was not significantly associated with changes in the SUSI (cSUSI: − 0.04, 95% CI: − 0.07;0.00, p = 0.052), while patients over 60 years of age had a lower SUSI than those under the age of 30 at baseline (difference in SUSI: − 0.08, 95% CI: − 0.14;− 0.01, p = 0.018), with no change over time (cSUSI: − 0.05, 95% CI: − 0.16;0.05, p = 0.297).

Conclusion

The present study demonstrates that inpatient detoxification was not associated with substance use changes over time for patients undergoing outpatient SUD treatment. Otherwise, injecting substance use was a particular risk factor for a high level of substance use. Future research needs to evaluate the impact of other treatment approaches on substance use, ideally in randomized controlled trials.
