Barriers to implementing evidence-based practices in addiction treatment programs: comparing staff reports on Motivational Interviewing, Adolescent Community Reinforcement Approach, Assertive Community Treatment, and Cognitive-behavioral Therapy.

PURPOSE This qualitative study explored barriers to implementing evidence-based practices (EBPs) in community-based addiction treatment organizations (CBOs) by comparing staff descriptions of barriers for four EBPs: Motivational Interviewing (MI), Adolescent Community Reinforcement Approach (A-CRA), Assertive Community Treatment (ACT), and Cognitive-behavioral Therapy (CBT). METHODS The CBOs received CSAT/SAMHSA funding from 2003 to 2008 to deliver services using EBPs. Phone interview responses from 172 CBO staff directly involved in EBP implementation were analyzed using content analysis, a method for making inferences and developing themes from the systematic review of participant narratives (Berelson, 1952). RESULTS Staff described different types of barriers to implementing each EBP. For MI, the majority of barriers involved staff resistance or organizational setting. For A-CRA, the majority of barriers involved specific characteristics of the EBP or client resistance. For CBT, the majority of barriers were associated with client resistance, and for ACT, the majority of barriers were associated with resources. DISCUSSION EBP designers, policy makers who support EBP dissemination and funders should include explicit strategies to address such barriers. Addiction programs proposing to use specific EBPs must consider whether their programs have the organizational capacity and community capacity to meet the demands of the EBP selected.

Modifications of evidence-based practices in community-based addiction treatment organizations: A qualitative research study

This qualitative research effort explored implementation of evidence-based practices (EBPs) in 100 community-based addiction treatment organizations (CBOs) nationwide. The study describes CBO program director attitudes on: (1) satisfaction with EBPs they were mandated to implement; (2) the extent to which their organization modified the EBPs; (3) reasons for modifications; and, (4) the standards they used for modifications. Findings indicate that program directors were highly positive both about EBPs implemented and the modifications made to those EBPs. A broad range of modifications were identified; most common were adding or deleting intervention sessions in efforts to serve the needs of a specific client population. Given the addiction treatment fields lack of standards for modifying EBPs, it is not surprising that little consistency occurred in modification efforts. As government funders of addiction treatments require that CBOs implement EBPs, standards need to be created for modifying and adapting the EBPs while maintaining their fidelity.

Client retention in residential drug treatment for Latinos

Client drop out from treatment is of great concern to the substance abuse field. Completion rates across modalities vary from low to moderate, not ideal since length of stay has been positively and consistently associated with better client outcomes. The study explored whether client characteristics shown to be related to retention were associated with treatment completion and treatment duration for a sample of 164 Latino substance users who entered a culturally focused residential program. In-person client interviews were conducted within a week of program admission. Logistic regression analysis was used to examine research questions. Clients most likely to drop out had self-reported co-occurring psychiatric diagnoses; they were 81% less likely to complete the program, suggesting that clients with mental health problems have a more difficult time remaining in residential treatment. Clients using drugs in the three months prior to entry were three and a half times more likely to be in the shorter stay group, and clients who lived in institutions prior to program entry were three times more likely to be in the longer-stay group. Factors contributing to drop out for this Latino sample were similar to those identified in the literature for non-Latino samples. Methods for addressing the needs of clients with co-occurring disorders are discussed.

Barriers to implementation of evidence-based addiction treatment: A national study

Prior studies have identified that working in an addiction treatment unit with higher levels of organizational capacity is a factor associated with positive staff attitudes about evidence-based addiction treatment practices (EBPs). The study presented here explored whether staff perceptions about the organizational capacity of their treatment unit are also associated with staff experience of barriers to implementing EBPs. Multivariate regression methods examined the relationship between the clinical staff (n = 510) and director (n = 296) perceptions of organizational capacity (Texas Christian University Organizational Readiness for Change [TCU ORC]-staff and TCU ORC-director) and level of barriers experienced when implementing a new EBP controlling for a range of treatment unit characteristics, staff characteristics, and type of EBP implemented. For both samples, reporting higher levels of stress in their organizations was significantly associated with reporting higher levels of barriers when implementing a new EBP. For clinical staff only, experiencing lower levels of program needs in their organization, working in a program that had been in existence for a shorter period, and implementing motivational interviewing techniques compared with other EBPs were all factors significantly associated with experiencing lower levels of barriers with EBP implementation.

Factors associated with HIV/AIDS high-risk behaviours among female injection drug users

Abstract This study examined factors associated with reporting engaging in HIV/AIDS high-risk behaviours at two different time points spaced one year apart for a sample of 185 women who were active injection drug users (IDUs). The high-risk behaviours included injecting drugs in the past six months, having shared needles in the past six months and having engaged in unprotected sexual activity in the past thirty days. Through logistic regression modelling it was identified that living with a spouse at year one was significantly and positively associated with high-risk behaviours at both time points. Being prescribed medications for psychological or emotional problems as well as testing positive for the HIV/AIDS virus were significantly and negatively associated with reporting high-risk behaviours at both time points. These results suggest that spousal relationships may play an important role in HIV/AIDS high-risk behaviours of women drug users. An implication of this study is the need to focus on how spousal relationships and issues such as gender and empowerment should be incorporated into the design and implementation of HIV/AIDS prevention and treatment programs. The benefits of comprehensive mental health diagnosis and treatment services as well as HIV testing in reducing harm to female IDUs and their partners are also discussed.

Examining Drug Treatment Entry Patterns Among Young Injection Drug Users

Using a longitudinal state data base, 1996–2002, of all Injection Drug Users (IDU) (n = 37,227) admissions to all state-licensed drug treatment programs, this study examined differences in drug treatment entry patterns between younger IDUs (ages 18–25) compared to middle-age IDUs (ages 26–39) and older IDUs (over 40 years of age). Most of the younger IDUs were male, unemployed, and dependent on heroin. After controlling for factors known to affect type of drug treatment entered, younger IDUs were significantly more likely than their older counterparts to only use detoxification services and not enter additional treatment. Further, younger IDUs were significantly less likely to enter methadone maintenance and significantly more likely to enter residential treatment compared to older IDUs. Development of strategies to promote transition from detoxification to more comprehensive treatments and especially to methadone maintenance treatment is warranted.

Factors Associated with Emergency Room Use among Injection Drug Users of African-American, Hispanic and White European Background

This study examined the relationship between substance abuse treatment use, health services use, HIV status, and emergency room/hospital use for 507 injection drug users (IDUs). Logistic regression models showed that mental health status, severity of drug use and private health insurance were significantly associated with having used emergency room/hospital services in the past six months. History of substance abuse treatment use, positive HIV/AIDS diagnosis, mental health service use, ethnic/racial background, gender, age, education and homelessness were not significant at either the bivariate or the multivariate level. These results point to the need to improve mental health screening and referrals through emergency room medical systems.

Use of mental health and substance abuse treatment services by female injection drug users.

This article examines whether female injection drug users (IDUs) who have a history of using mental health services (i.e., one or more psychiatric hospitalizations or counseling) enter types of drug treatment different from those of female IDUs who do not have a history of using mental health services. Data used for this exploration originate from a statewide drug‐treatment database covering all women who entered drug treatment in the state of Massachusetts from 1996 to 2001. A total of 7776 women were included in the study. Through the use of logistic regression analysis, the study determined that those female IDUs who had a mental health service history, compared with female IDUs who had no such history, were about two‐thirds more likely to enter substance abuse treatment other than detoxification only. Specifically, women with a mental health service history were about 66% more likely to enter substance abuse treatment modalities such as drug‐free outpatient counseling, methadone maintenance, and/or long‐term residential services rather than detoxification alone. This is a positive result, indicating that female IDUs who have mental health problems and therefore have high needs for effective substance abuse treatment are entering the more intensive and/or longer term modalities likely to lead to better outcomes. Possible factors accounting for this, including the referral process within detoxification centers, the role of community referral agents, and the experience women gain as a consequence of receiving services in more than one service system, are discussed.

Organizational readiness for change in community-based addiction treatment programs and adherence in implementing evidence-based practices: a national study

UNLABELLED Prior studies by the authors identified that clinical staff who reported that their treatment unit had lower levels of organizational readiness to change experienced higher levels of barriers in implementing an evidence-based practice (EBP). The current study examined whether clinical staff perceptions of their treatment units organizational readiness to change were also associated with their adherence to EBP protocols during EBP implementation. Adherence was examined through a variable measuring the extent to which staff modified EBP standards and manuals when implementing a new EBP. Multivariate regression analyses identified that clinical staff who had five or more years of addiction counseling experience, who rated staff in their organization as having higher levels of influence, who less frequently implemented new counseling interventions and who reported higher levels of barriers when implementing a newly funded EBP also reported that their program made more modifications to the EBP in the implementation process. Finally, staff who implemented MI compared to any other EBP reported lower levels of EBP modifications. IMPLICATIONS Continued federal funding is needed to enhance treatment unit organizational resources in order to reduce barriers and promote adherence to EBPs. Also, funders of treatment need to continue to provide ongoing technical assistance and training opportunities to promote implementation of EBPs with fidelity.

What Factors Are Associated with High-Frequency Drug Treatment Use among a Racially and Ethnically Diverse Population of Injection Drug Users?

This study explored the frequency of drug treatment utilization by 36,081 injection drug users (IDUs) in Massachusetts, 1996-2002. A number of multiple and logistic regression analyses examined the relationship between demographic characteristics, parental status, level of and type of drug use, history of mental health treatment use, types of drug treatment entered, and the number of times an IDU had entered drug treatment for the seven-year time period. Homelessness, using heroin as the primary drug of choice, and health insurance status were all associated with number of treatments entered. Logistic regression analysis identified that health insurance was a key factor associated with more frequent treatment: those with private health insurance were ten times more likely to be in the 90th percentile (12-107 entries) with respect to number of treatment entries.
