Inpatient vs outpatient treatment for substance dependence revisited

Factors Associated with Unplanned Early Discharges from a Dual Diagnosis Inpatient Detoxification Unit in Israel

OBJECTIVES

Currently, Israel has a single governmental inpatient dual diagnosis detoxification unit. We provide a cross-section of patient profiles in this study as well as explore possible associations between clinical/demographic factors and the unplanned early discharge of patients from the unit, aiming at improving rehabilitation success rates.

METHODS

In this retrospective study, medical records of all patients admitted to the unit between January 1, 2012, and July 1, 2013, were examined (N = 323). ICD-10 was used for diagnosis. Statistical analysis was carried out using Pearson's chi-squared test and binary logistic regression.

RESULTS

Patients admitted to our unit were affected by schizophrenia (31.8%), personality disorder (25%), and depression (18.3%). Substances in use included alcohol (67.5%), cannabis (8.35%), and benzodiazepines (9%). Almost half of the patients were polysubstance users (48.9%). The unit had high rates of immigrants, mainly ex-USSR- and Ethiopian-born. It had low rates of individuals who had served in the army (52.8%), despite the service being mandatory in Israel. Sixty-eight percent of patients completed the program as planned, and 32% were discharged early: 8.6% discharged due to drug use in detoxification settings, violence, or hospitalization for clinical reasons and 23.2% discharged against medical advice. Immigrants had increased rates of completing the program as scheduled. Of the 46.7% of patients with severe mental illness, 44.3% were discharged early. Higher education and a diagnosis of depression were associated with program completion as planned. Using logistic regression, we found that patients with disability pensions (odds ratio [OR] = 0.36; 95% confidence interval [CI] [0.14-0.91]; p = .03) and polysubstance use (OR = 0.39; 95% [CI] [0.23, 0.66], p < .001) had a higher risk of early discharge. Upon completion of individual programs, 52% were referred to an ambulatory addiction center and 13% to a nationally sponsored dual diagnosis therapeutic community.

CONCLUSIONS

Israel's single official dual diagnosis detox inpatient unit has satisfactory annual program completion rates when compared to similar institutions. A suboptimal treatment regimen may contribute to the early discharge of patients with polysubstance use and diagnosed personality disorders. An association between early discharges and a disability pension warrant further investigation, as there is no apparent connection between the two.

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.

Drop-out from addiction treatment: a systematic review of risk factors

Completion of addiction treatment is one of the most consistent factors associated with a favorable treatment outcome. Unfortunately, it is more common for a patient to drop-out of addiction treatment than to complete the treatment. To prevent drop-out, risk factors must be identified. This box-score review focuses on studies investigating the risk factors associated with drop-out from addiction treatment published in peer-reviewed journals from 1992 to 2013. A total of 122 studies involving 199,331 participants met the inclusion criteria. Contrary to recommendations from previous reviews, 91% of the included studies focused primarily on enduring patient factors, mainly demographics. The most consistent risk factors across the different study designs, samples, and measurement methods were cognitive deficits, low treatment alliance, personality disorder, and younger age. With the exception of younger age, none of the demographic factors emerged as consistent risk factors. Further research on the relationship between simple demographic factors and drop-out risk is of limited value. However, little is known about the potential risk factors related to treatment programs and to the treatment processes. Based on the review, clinical recommendations include assessing cognitive functioning and personality disorders at baseline and continuous monitoring of treatment alliance.

Factors associated with first utilization of different types of care for alcohol problems

OBJECTIVE

The purpose of this research was to investigate whether factors associated with first obtaining care for alcohol problems vary by source of care.

METHOD

This study used data from the National Epidemiologic Survey on Alcohol and Related Conditions to examine initiation of different types of care over a 3-year follow-up interval among individuals with baseline alcohol use disorders who had not previously obtained any care (n = 2,170). Three hierarchical, mutually exclusive types of care were compared: substance use disorder (SUD) specialty sources, general medical but no SUD specialty sources, and nonmedical sources only.

RESULTS

Having injured oneself or someone else because of drinking was associated with initiating all three types of care. Additional factors associated with initiating care from SUD specialty treatment sources (vs. no care) comprised male sex, alcohol use disorder severity, major financial problems, and nondependent tobacco/drug use. Factors associated with initiating care from general medical but not SUD specialty sources (vs. no care) comprised marriage/cohabitation, college student status, number of medical conditions, and other substance dependence. Factors associated with obtaining care only from nonmedical sources (vs. no care) comprised low income and anxiety disorder. When direct comparisons were made among types of care, factors drawing individuals into general medical care for reasons not necessarily related to alcohol problems were those that primarily distinguished utilization of general medical sources from the other two types of care.

CONCLUSIONS

Results support the importance of screening in general medical practice and student health services as an important means of identifying individuals in need of brief intervention or more intensive SUD treatment and reiterate the importance of nonmedical sources for individuals whose alcohol problems might never be addressed in routine medical visits.

Client-Provider relationship in comprehensive substance abuse treatment: differences in residential and nonresidential settings

As the substance abuse service system shifts from primarily residential to primarily nonresidential settings, it becomes important to understand how substance abuse treatment processes and outcomes may vary across service setting. Research increasingly indicates that, along with specific treatment and service strategies, client-provider relationship is an important ingredient in effective substance abuse treatment. This study uses a moderator-mediator analysis of a comprehensive service model to examine how the relation between client-provider relationship and substance abuse treatment outcomes may differ in residential and nonresidential settings. The study used data collected for the National Treatment Improvement Evaluation Study, a prospective, cohort-based study of U.S. substance abuse treatment programs and their clients, with an analytic sample of 59 publicly funded service delivery units and 3,027 clients. Structural equation modeling is used to assess the structural relations and causal connections between treatment process and treatment outcome variables. Results indicate that for nonresidential settings, a better client-provider relationship is directly related to improved outcomes of treatment duration and reduced posttreatment substance use and is indirectly related to both outcomes through provision of services matched to client needs. In residential settings, the quality of the client-provider relationship is unrelated to process or outcome variables. The findings point to the importance of the client-provider relationship in all settings but particularly in outpatient settings where there are limited physical constraints on the treatment process.

The appropriateness of the treatment setting for the inpatient post-acute treatment of alcohol dependence disorders in Switzerland

BACKGROUND

In Switzerland, a total of 1'000 patients a year are treated for alcohol-dependence in specialized institutions. Though the current literature suggests favoring outpatient treatment, whether outpatient or inpatient treatment is more efficient cannot be answered generally. For Germany, "AWMF"-treatment guidelines were formulated in order to treat patients with substance use disorders in the appropriate treatment settings. The aim of the present study was to test the hypothesis that the majority of patients treated in the largest specialized institution for alcohol abuse treatment in Switzerland were treated in the appropriate setting.

METHODS

All completed treatments conducted in the Forel-Hospital - the largest clinic of its kind in Switzerland - between the 1st of January 2004 and the 20th of December 2006 were included in the investigation (n = 915). Patient and treatment characteristics were gathered using the information from the PSYREC and act-info questionnaire. The AWMF criteria were operationalized on the basis of the questionnaire.

RESULTS

Applying the AWMF criteria resulted in the emergence of three groups: 73.7% of the study sample could clearly be assigned to the inpatient treatment group, and for 7.5% there was evidence supporting the allocation to an outpatient treatment setting. In 18.8% of the cases, however, the AWMF criteria did not allow an assignment to either of the treatment settings. Of the total sample, 18.5% of all patients apparently did not profit from the inpatient treatment setting, whereas for the vast majority (81.5%), a therapeutic progress was documented. In those patients who, according to the AWMF guidelines, did not need an inpatient setting, a larger proportion improved than in the group of the patients who needed an inpatient treatment in a specialized hospital. Furthermore, the logistic regression analyses revealed that the less severe the clinical state of a patient upon admittance, the higher the odds of improvement during the hospital stay.

CONCLUSION

The results serve as evidence that for at least three out of four patients treated in the investigated specialized institution, an inpatient treatment was appropriate. The principal reason for the necessity of an inpatient treatment setting was that this hospital population showed severe psychiatric, somatic or social irregularities. Only a very limited number of patients hospitalized in a specialized institution for the treatment of alcohol-related disorders can be treated in an outpatient setting.

The interplay between help-seeking and alcohol-related outcomes: divergent processes for professional treatment and self-help groups

This study examined the influence of self-selection, as reflected in alcohol-related functioning, on the duration of professional treatment and Alcoholics Anonymous (AA), and the influence of social causation, as reflected in the duration of treatment and AA, on alcohol-related outcomes. A sample of alcoholic individuals was surveyed at baseline and 1, 3, and 8 years later. At each point, participants completed an inventory that assessed participation in treatment and AA since the last assessment and alcohol-related functioning. There were divergent processes of self-selection and social causation with respect to the duration of participation in professional treatment and AA. Individuals with more severe alcohol-related problems obtained longer episodes of professional treatment, but this self-selection process was much less evident for AA. Longer participation in professional treatment in the first year predicted better alcohol-related outcomes; however, the duration of subsequent treatment was not associated with better subsequent outcomes. In contrast, longer participation in AA consistently predicted better subsequent alcohol-related outcomes. These findings are consistent with a need-based model of professional treatment, in which more treatment is selected by and allocated to individuals with more severe problems, and an egalitarian model of self-help, in which need factors play little or no role in continued participation.

Success of Referral for Alcohol Dependent Patients from a General Hospital

To assess the effectiveness of a multidisciplinary evaluation and referral process in a prospective cohort of general hospital patients with alcohol dependence. Alcohol-dependent patients were identified in the wards of the general hospital and its primary care center. They were evaluated and then referred to treatment by a multidisciplinary team; those patients who accepted to participate in this cohort study were consecutively included and followed for 6 months. Not included patients were lost for follow-up, whereas all included patients were assessed at time of inclusion, 2 and 6 months later by a research psychologist in order to collect standardized baseline patients' characteristics, process salient features and patients outcomes (defined as treatment adherence and abstinence). Multidisciplinary evaluation and therapeutic referral was feasible and effective, with a success rate of 43%for treatment adherence and 28%for abstinence at 6 months. Among patients' characteristics, predictors of success were an age over 45, not living alone, being employed and being motivated to treatment (RAATE-A score < 18), whereas successful process characteristics included detoxification of the patient at time of referral and a full multidisciplinary referral meeting. This multidisciplinary model of evaluation and referral of alcohol dependent patients of a general hospital had a satisfactory level of effectiveness. Predictors of success and failure allow to identify subsets of patients for whom new strategies of motivation and treatment referral should be designed.

Long-term influence of duration and intensity of treatment on previously untreated individuals with alcohol use disorders

AIMS

This study examined the influence of the duration and intensity of the first episode of treatment for previously untreated individuals with alcohol use disorders on short-term and long-term outcomes, and the effect of additional treatment and delayed treatment on outcomes.

DESIGN, SETTING, PARTICIPANTS

A sample of alcoholic individuals (n = 473) was recruited at alcoholism information and referral centers and detoxification units and was surveyed at baseline and 1 year, 3 years and 8 years later.

MEASUREMENTS

At each contact point, participants completed an inventory that assessed their treatment utilization since the last assessment and their current alcohol-related, psychological and social problems.

FINDINGS

Compared with individuals who remained untreated, individuals who entered treatment relatively quickly and who obtained a longer duration of treatment had better short- and long-term alcohol-related outcomes and better short-term social functioning. Individuals who obtained a longer duration of additional treatment had better alcohol-related outcomes than individuals who obtained no additional treatment but, among individuals who delayed treatment entry, the duration of treatment was not associated with treatment outcomes. In general, the intensity of treatment was not related to better outcomes.

CONCLUSIONS

Rapid entry into treatment and the duration of treatment for alcohol use disorders may be more important than the intensity of treatment. Treatment providers should consider structuring their programs to emphasize continuity, rather than intensity of care.

Evaluation of full vs. partial continuum of care in the treatment of publicly funded substance abusers in Washington State

This study evaluated the relative effectiveness of two forms of publicly funded substance abuse treatment provided in Washington State: The full continuum (FC), in which clients receive approximately three weeks of inpatient treatment prior to outpatient care, and the partial continuum (PC), in which clients are admitted directly to outpatient treatment. Data on treatment process/proximal outcomes, such as psychological distress and readiness to change, were assessed at 8 weeks post intake, and data on treatment services received were obtained at 2, 4, 8, and 12 weeks. Multidimensional outcomes, including alcohol and drug use as well as a number of psychosocial functioning outcomes, were assessed at 3 and 9 months post intake. Results indicated that clients in the FC had greater alcohol, drug, and legal problem severity at intake than those in the PC, whereas medical and employment problem severity was greater in the PC. Clients in the FC received more treatment services in the first 2 weeks than those in the PC, but there were no differences at subsequent points. Outcome analyses at 3 and 9 months indicated that clients in the FC had greater improvements in alcohol, drug, and psychiatric severity than those in the PC. Matching analyses indicated that clients with greater substance-use severity at baseline improved to a greater degree in the FC as compared to the PC. Matching effects were not obtained with medical or psychiatric severity, or readiness to change.

Interaction effects of treatment setting and client characteristics on retention and completion

Client-treatment matching assumes treatment outcome will be improved if characteristics of clients are matched to specific elements of treatment. Few empirical studies, however, have examined matching across different types of treatment settings. The present research examined differences in demographics and substance-related problems in populations admitted to three substance abuse treatment settings--outpatient (n = 1132), intensive outpatient (n = 1190), and residential (n = 149)--and tested whether interactions between client characteristics and type of setting predicted rates of 30-day retention and treatment completion. In addition, three specific hypotheses based on prior theoretical and empirical investigations were tested. Client characteristics included demographic information (e.g., sex, age, race) and Addiction Severity Index (ASI) composite scores. Client-setting interactions were found for both retention and completion. All three hypotheses received at least partial support. Implications for client assignment and future research are discussed.

Relapse outcomes in a randomized trial of residential and day drug abuse treatment

Relapse outcomes at 6-, 12-, and 18-month intervals were compared between clients randomly assigned to day (n=114) versus residential (n=147) drug abuse treatment. Day clients were more likely than residential clients to relapse 6 months post-admission (OR=3.06, p<0.001); however, no setting differences at 12 or 18 months were found. Few baseline predictors were prospectively related to relapse at 12 and 18 months. These predictors were usual employment status (part-time OR=17.47, p<0.001; full-time OR=2.54, p<0.001), history of drug injecting (OR=5.39, p<0.01), multiple sex partners (OR=1.16, p<0.01), and not having a gay sexual partner (OR=0.05, p<0.03) during 6 months prior to admission. Still, these baseline predictors, together with the existing literature, could be used by drug treatment professionals to identify individuals who may be at high risk for relapse over time, and to offer specialized treatment and aftercare resources as intervention and prevention measures.

Accountability in public short-term adult AOD residential treatment. Fontainebleau Treatment Center

Fontainebleau Treatment Center provides short-term public residential AOD treatment and primary health care to a lower-socioeconomic adult population. The multimodal focus of treatment includes interactive group therapy, behavioral contracting, relapse prevention, and 12-step involvement. Research funded by the National Institute on Drug Abuse indicated both positive treatment outcome and significant cost efficacy. These results may be in some contrast to prevailing assumptions about public sector, government-operated behavioral health-care delivery to high-risk populations. Multiple variables for consideration in future outcome research are discussed, with potential for database inclusion toward standardization of treatment and cost protocols.

Treatment matching. Theoretic basis and practical implications

An extensive knowledge base supports the development of treatment matching methods for alcohol and other drug abuse. Many matching variables have been identified that relate to specific modalities of treatment and to specific levels of care. Physicians and other providers can use many putative matching variables to address patients' substance use problems on a highly individualized basis. These variables include demographic factors (age, gender, culture), typology and severity (age of onset; severity of intoxication; withdrawal; quantity, recency, frequency of substance use), intrapersonal characteristics (psychiatric diagnosis, cognitive function, self-efficacy, stage of change), and interpersonal function (social stability). The evolution of formal criteria for patient placement such as the ASAM criteria is a beneficial, adaptive process that is underway in numerous states, managed care entities, professional provider societies, and provider groups. Currently, matching approaches rely more heavily on consensus recommendations than on empiric matching data. The technology for conducting psychosocial treatment matching studies is rapidly increasing in sophistication. Although predictive validity has not yet been fully demonstrated on a large, multisite basis, the national research portfolio on treatment matching is expanding in size and complexity. This is an essential public health need, given dramatic cost pressures, if addiction services are to continue to grow in quality and availability.

The effectiveness of inpatient and outpatient treatment for alcohol abuse: the need to focus on mediators and moderators of setting effects

Previous reviews have concluded that there was no evidence for the superiority of inpatient over outpatient treatment of alcohol abuse, although particular types of patients might be more effectively treated in inpatient settings. In this review, we first consider the conceptual rationales that have been offered to support inpatient and outpatient treatment. Following that, the results of the relevant research on setting effects are presented. Five studies had significant setting effects favoring inpatient treatment, two studies found day hospital to be significantly more effective than inpatient treatment, and seven studies yielded no significant differences on drinking-related outcome variables. In all but one instance in which a significant effect emerged, patients in the 'superior' setting received more intensive treatment and patients were not 'preselected' for their willingness to accept random assignment to treatment in either setting. Studies finding significant setting effects also conducted more treatment contrasts (18.6 vs. 4.9), on average, and had a mean statistical power level of 0.71 (median 0.79) to detect a medium-sized effect, whereas studies with no significant findings had an average power level of 0.55 (median 0.57). When inpatient treatment was found to be more effective, outpatients did not receive a respite in the form of inpatient detoxification and the studies were slightly less likely to have social stability inclusion criteria and to use random assignment to treatment settings. We consider the implications of our findings for future research, especially the need to examine the conceptual rationales put forward by proponents of inpatient and outpatient treatment, i.e. mediators and moderators of setting effects.

The natural history of outpatient alcohol and drug abuse treatment in a private healthcare setting

Managed healthcare has had a major impact on the delivery of alcohol and drug abuse treatment services in the private setting, primarily by shifting patient enrollment from inpatient to outpatient treatment programs. The purpose of this study was to investigate the natural history of outpatient alcohol and drug abuse treatment in a private, nonprofit healthcare setting. Patient profiles at pretreatment, their attendance record in a 6-week outpatient program, and their outcome in the year after treatment were evaluated in 120 patients with a DSM-III-R diagnosis of alcohol and/or cocaine dependence. There were 70 outpatients who successfully completed the program, and 50 who did not. Two subtypes of outpatient treatment failures were identified: S5 who prematurely left treatment against medical advice (n = 23), and S8 who attended treatment but continued heavy use of substances (Treatment Resistant, n = 27). A logistic regression revealed that younger age, multiple prior treatments, and employment problems were related to outpatient treatment failure. Outpatient failures did not immediately seek alternative treatment, and most of them continued heavy substance use in the year post-treatment: i.e., 82% vs. 43% successful completers (chi 2 = 13.8, df = 1, p < 0.01). Thus, there were a clinically relevant number of outpatient failures (42%), either because of lack of program attendance or continued substance use throughout treatment. These behaviors were related to continued heavy use of substances in the year after treatment.

Negative alcohol expectancy predicts post-treatment abstinence survivorship: the whether, when and why of relapse to a first drink

Using survival analysis, the association was explored between positive and negative alcohol expectancies measured on admission to a non-residential alcohol dependence treatment unit and post-treatment relapse to a first drink (first slip). A reliable association between negative alcohol expectancy (but not positive) and relapse was found. The active negative alcohol expectancies were distal rather than proximal: proximal expectancies surround consumption ('same day' expectancies) and distal expectancies relate to the 'next-day' following consumption or those longer term expectancies coming from 'continued drinking'. Only the 'next day' component of distal expectancies formed a reliable association with relapse. The use to which negative alcohol expectancy as measured by the Negative Alcohol Expectancy Questionnaire might be put is discussed in terms of (i) a bottom-up representation of motivation for recovery to help treatment match and (ii) a provisor of detailed, client-specific information for structuring motivational interventions.
