Factors associated with the adoption of evidence-based innovations by substance use disorder treatment organizations: A study of HIV testing

IntroductionThough prior research shows that a range of important regulatory, market, community, and organizational factors influence the adoption of evidence-based practices (EBPs) among health care organizations, we have little understanding of how these factors relate to each other. To address this gap, we test a conceptual model that emphasizes indirect, mediated effects among key factors related to HIV testing in substance use disorder treatment organizations (SUTs), a critical EBP during the US opioid epidemic. MethodsWe draw on nationally representative data from the 2014 (n = 697) and 2017 (n = 657) National Drug Abuse Treatment System Survey (NDATSS) to measure the adoption of HIV testing among the nation's SUTs and their key organizational characteristics; we also draw on data from the US Census Bureau; Centers for Disease Control; and legislative sources to measure regulatory and community environments. We estimate cross-sectional and longitudinal structural equation models (SEM) to test the proposed model. ResultsOur longitudinal model of the adoption of HIV testing by SUTs in the United States identifies a pathway by which community and market characteristics (rurality and the number of other SUTs in the area) are related to key sociotechnical characteristics of these organizations (alignment of clients, staff, and harm-reduction culture) that, in turn, are related to the adoption of this EBP. ConclusionsResults also show the importance of developing conceptual models that include indirect effects to account for organizational adoption of EBPs.

The relationship of Medicaid expansion to psychiatric comorbidity care within substance use disorder treatment programs

BackgroundCo-occurring mental health disorders are common among substance use disorder (SUD) patients. Medicaid expansion aimed to reduce barriers to SUD and mental health care and thereby improve treatment outcomes. MethodsWe estimated change in the proportion of United States SUD treatment sites offering treatment for psychiatric comorbidities following Medicaid expansion as part of implementation of the Affordable Care Act (ACA) in 2014. Using panel data from the 2013–2014, n = 660, and 2016–2017, n = 638, waves of the National Drug Abuse Treatment System Survey (NDATSS), we estimated change in the proportion of sites offering antidepressant medication, other psychiatric medication, behavioral treatment, or any combination thereof for treatment of mental health comorbidities (i.e., beyond services focused on SUD). We modeled the impact of Medicaid expansion as an interaction between year and date of Medicaid expansion. We constructed a mixed-effects linear regression model for each outcome, with the interaction variable as the main exposure, site as a random effect, and site's average duration of treatment, proportion of clients with psychiatric comorbidities, average caseload per treatment prescribing-clinician on staff, type of facility and geographic region as covariates, to estimate a difference-in-differences (D-I-D) equation. ResultsThe adjusted D-I-D analysis indicated that the proportion of SUD treatment sites offering antidepressants for psychiatric treatment increased 10% (95% CI 1%, 18%) in the Medicaid expansion sites compared to non-expansion sites. The D-I-D for other psychiatric medications was also 10% (95% 1%, 19%). No significant changes were observed in behavioral treatment or the combination measure. The strongest association between Medicaid expansion and offering medication for mental health comorbidities was the 34% increase observed for residential treatment settings (95% CI 10%, 59%). ConclusionAvailability of psychiatric medication treatment in SUD treatment settings increased following Medicaid expansion, particularly in residential SUD facilities. This policy change has facilitated integrated treatment for the substantial share of SUD treatment patients with mental health comorbidities, with the greatest benefit for patients receiving SUD treatment in residential programs.

Spillover effects of HIV testing policies: changes in HIV testing guidelines and HCV testing practices in drug treatment programs in the United States.

BackgroundTo examine the extent to which state adoption of the Centers for Disease Control and Prevention (CDC) 2006 revisions to adult and adolescent HIV testing guidelines is associated with availability of other important prevention and medical services. We hypothesized that in states where the pretest counseling requirement for HIV testing was dropped from state legislation, substance use disorder treatment programs would have higher availability of HCV testing services than in states that had maintained this requirement.MethodsWe analyzed a nationally representative sample of 383 opioid treatment programs from the 2005 and 2011 National Drug Abuse Treatment System Survey (NDATSS). Data were collected from program directors and clinical supervisors through telephone surveys. Multivariate logistic regression models were used to measure associations between state adoption of CDC recommended guidelines for HIV pretest counseling and availability of HCV testing services.ResultsThe effects of HIV testing legislative changes on HCV testing practices varied by type of opioid treatment program. In states that had removed the requirement for HIV pretest counseling, buprenorphine-only programs were more likely to offer HCV testing to their patients. The positive spillover effect of HIV pretest counseling policies, however, did not extend to methadone programs and did not translate into increased availability of on-site HCV testing in either program type.ConclusionsOur findings highlight potential positive spillover effects of HIV testing policies on HCV testing practices. They also suggest that maximizing the benefits of HIV policies may require other initiatives, including resources and programmatic efforts that support systematic integration with other services and effective implementation.

Hepatitis C testing in substance use disorder treatment: the role of program managers in adoption of testing services.

BackgroundHealth care organizations do not adopt best practices as often or quickly as they merit. This gap in the integration of best practices into routine practice remains a significant public health concern. The role of program managers in the adoption of best practices has seldom been investigated.MethodsWe investigated the association between characteristics of program managers and the adoption of hepatitis C virus (HCV) testing services in opioid treatment programs (OTPs). Data came from the 2005 (n = 187) and 2011 (n = 196) National Drug Abuse Treatment System Survey (NDATSS). We used multivariate regression models to examine correlates of the adoption of HCV testing. We included covariates describing program manager characteristics, such as their race/ethnicity, education, and their sources of information about developments in the field of substance use disorder treatment. We also controlled for characteristics of OTPs and the client populations they serve.ResultsProgram managers were predominantly white and female. A large proportion of program managers had post-graduate education. Program managers expressed strong support for preventive services, but they reported making limited use of available sources of information about developments in the field of substance use disorder (SUD) treatment. The provision of any HCV testing (either on-site or off-site) in OTPs was positively associated with the extent to which a program manager was supportive of preventive services. Among OTPs offering any HCV testing to their clients, on-site HCV testing was more common among programs with an African American manager. It was also more common when program managers relied on a variety of information sources about developments in SUD treatment.ConclusionsVarious characteristics of program managers are associated with the adoption of HCV testing in OTPs. Promoting diversity among program managers, and increasing managers’ access to information about developments in SUD treatment, may help foster the adoption of best practices.

Low Rates of Adoption and Implementation of Rapid HIV Testing in Substance Use Disorder Treatment Programs

IntroductionRapid HIV testing (RHT) greatly increases the proportion of clients who learn their test results. However, existing studies have not examined the adoption and implementation of RHT in programs treating persons with substance use disorders, one of the population groups at higher risk for HIV infection. MethodsWe examined 196 opioid treatment programs (OTPs) using data from the 2011 National Drug Abuse Treatment System Survey (NDATSS). We used logistic regressions to identify client and organizational characteristics of OTPs associated with availability of on-site RHT. We then used zero-inflated negative binomial regressions to measure the association between the availability of RHT on-site and the number of clients tested for HIV. ResultsOnly 31.6% of OTPs offered on-site rapid HIV testing to their clients. Rapid HIV testing was more commonly available on-site in larger, publicly owned and better-staffed OTPs. On the other hand, on-site rapid HIV testing was less common in OTPs that prescribed only buprenorphine as a method of opioid dependence treatment. The availability of rapid HIV testing on-site reduced the likelihood that an OTP did not test any of its clients during the prior year. But on-site availability rapid HIV testing was not otherwise associated with an increased number of clients tested for HIV at an OTP. ConclusionsNew strategies are needed to a) promote the adoption of rapid HIV testing on-site in substance use disorder treatment programs and b) encourage substance use disorder treatment providers to offer rapid HIV testing to their clients when it is available.

Can Cultural Competency Speak to the Race Disparities in Methadone Dosage Levels?

Although national methadone treatment trends have improved substantially from 1988 to 2001, current research has found that African Americans still receive lower dosages of methadone treatment than their white and Hispanic counterparts, which has significant public health concerns. We sought to empirically examine whether the degree of cultural competency within an outpatient substance abuse treatment (OSAT) organization has influence on the methadone dosage levels received by African Americans in 1995 and in 2005. The 1995 and 2005 National Drug Abuse Treatment System Survey (NDATSS) provided a nationally-representative, stratified sample of 618 and 566 OSAT organizations, respectively, of which 121 and 140 affiliated methadone maintenance treatment programs, respectively, were analyzed. The organizations' director and clinical supervisor were surveyed. Fixed-effects linear regression models were fitted with measures of cultural competency, client, and organizational characteristics to assess methadone dosage levels. Culturally-competent units have smaller numbers of methadone clients, greater percentages of clients who receive methadone dosages of less than 40 mg/d, smaller percentages of clients who receive methadone dosages of 80 mg/d or more, and provide a larger number of therapeutic and ancillary services during treatment than non-culturally-competent units. OSAT units with more African Americans are significantly more likely to have clients who receive dosages of less than 40 mg/d and are significantly less likely to have clients who receive dosages of 80 mg/d or more. There is no racial difference among culturally-competent unit clients who receive dosages of less than 40 mg/d, between 40 and 59 mg/d, between 60 and 79 mg/d, and 80mg/d or more. However, among non-culturally-competent units, a racial difference exists among African Americans and other clients who receive these various dosage levels. Research indicating that African Americans receive lower dosages of methadone than their White and Hispanic counterparts may now be explained by whether these clients receive treatment in culturally competent organizations, rather than solely by arguments related to organizational differences in resources, experience and training of staff, staff bias and/or racism. Culturally competent organizations may seek a method of treatment that dissuades “replacing one drug for another,” while simultaneously treating the root cause of the addiction through the provision of comprehensive therapeutic and ancillary support services. Further research is needed to determine if cultural competency results in better substance abuse treatment outcomes for African Americans.

Who Cares for Involuntary Clients?

ABSTRACT The objectives of this study were to compare characteristics of outpatient substance abuse treatment (OSAT) units that serve high proportions of involuntary clients (ICs) with those that serve a low percentage of such clients. The authors analyze unit-level 1995–2005 data from the National Drug Abuse Treatment System Survey (NDATSS). Approximately 1/6 of OSAT units draw the dominant majority of their clients from involuntary referrals. OSAT units that treat a high proportion of ICs are less likely to be accredited by professional organizations, have fewer treatment staff with advanced degrees, and have shorter average treatment duration than do OSAT units that serve few ICs. OSAT units that serve ICs are more likely to offer legal and domestic violence services but are less likely to offer mental health services or aftercare. OSAT units that serve ICs are less likely to be hospital-affiliated than are other units. Clients at such facilities are more likely to be convicted of driving while intoxicated (DWI), are younger, are less likely to have received prior treatment, are more likely to remain abstinent after treatment, but are more likely to be remanded back to courts. The authors conclude that ICs are an important market niche in OSAT care. DWI is by far the most common offense reported in units that specialize in ICs. Aside from legal and domestic violence services, units with a high proportion of ICs appear to offer somewhat less intensive and professionalized services than do other facilities; however, clients at these units are more likely to be abstinent at the end of treatment and but more likely to be remanded back to the courts.

Outpatient substance abuse treatment and HIV prevention: An update

Testing and counseling, along with community outreach, have been identified as valuable in the prevention of human immunodeficiency virus (HIV) and other blood-borne diseases. This article assesses the extent to which outpatient substance abuse treatment (OSAT) programs provide such services. Longitudinal data for 1988–2000 were analyzed from the National Drug Abuse Treatment System Survey (NDATSS). Random-effects regression was used to examine factors associated with the provision of prevention services. HIV testing, which had became more common between 1990 and 1995, continued to proliferate between 1995 and 2000. The proportion of units that provide HIV testing and counseling increased from 66% to 86%. The proportion of units that provide HIV community outreach increased significantly before 1995 but then slightly decreased from 77% to 73% between 1995 and 2000. In conclusion, HIV testing and counseling widely proliferated in OSAT care. However, OSAT units remain less likely to offer HIV community outreach services.

Organizational Survival in the Outpatient Substance Abuse Treatment Sector, 1988-2000

Substance abuse remains one of the most pressing health issues in the United States today, yet treatment supply continues to lag far behind need. Given the hostile environments treatment facilities face, their survival is a matter of pressing policy concern. Results from analyses of National Drug Abuse Treatment System Survey (NDATSS) data from 1988 through 2000 suggest that organizational attributes such as age, size, and client severity and resource dependencies such as reliance on government revenue affect survival, but their effects change over time. By the mid-1990s, director involvement in state and local policy making was positively associated with subsequent survival; later that decade, directors' professional credentials affected survival as well. Results also show that serving clients with multiple substance abuse problems became a survival liability by the late 1990s. Facilities that treat clients with multiple addictions may need additional financial support to serve these particularly vulnerable clients.

Factors That Influence Staffing of Outpatient Substance Abuse Treatment Programs

This study examined whether and how various organizational and environmental forces influence staffing in outpatient substance abuse treatment programs. The authors used data from the 1995 and 2000 waves of the National Drug Abuse Treatment System Survey (NDATSS), a telephone survey of unit directors and clinical supervisors. Multivariate analyses with generalized estimating equations were conducted. Two measures of staffing were modeled: the number of weekly treatment hours per client, and active caseload. Managed care activity influenced active caseloads but not the number of treatment hours per client. Significant differences were noted in staffing levels among private for-profit, private nonprofit, and public treatment programs, with public units offering fewer hours per client and having larger caseloads. Units accredited by the Joint Commission on Accreditation of Healthcare Organizations offered more treatment hours per client. The results of this study contribute to the understanding of various influences on treatment staff time and caseloads. Understanding these relationships is critical for policy makers, managed care companies, and managers, because staffing levels have the potential to affect both the cost and the quality of treatment.

Factors Associated with Interorganizational Relationships among Outpatient Drug Treatment Organizations 1990–2000

To identify the factors associated with drug abuse treatment center participation in interorganizational relationships (IORs). Three nationally representative samples of outpatient drug abuse treatment units surveyed in 1990, 1995, and 1999/2000 as part of the National Drug Abuse Treatment System Survey (NDATSS), stratified by public/private status, treatment modality (methadone or nonmethadone), and organizational affiliation. Probit analyses on 647 lagged treatment center-year observations from the years 1990 to 1995 with outcomes in 1995 and 2000, respectively. Standard errors were adjusted for clustering of center-year observations within centers. Centers with greater motivation to form IORs (e.g., as a result of client diversity or government revenue) were more likely to do so, as were centers with greater opportunities to form IORs (e.g., centers whose directors participated in policy making). Both motivating and enabling factors promoted the formation of IORs by drug abuse treatment centers. Managed care also played a distinct role, in this case appearing to undermine interorganizational cooperation. Because IORs can improve access to care and quality, policy makers should consider using both incentives and support such as management training to promote IOR formation.

Culturally competent treatment of African American clients among a national sample of outpatient substance abuse treatment units

This study measures the level of cultural competency with respect to African American clients that exists among a national sample of outpatient substance abuse treatment (OSAT) units and determines the relationship of cultural competency to various characteristics of these units and their clients. The study utilizes cross-sectional data from the 1995 National Drug Abuse Treatment System Survey (NDATSS). The sample for NDATSS was randomly selected from a comprehensive list of OSAT programs compiled by the Institute for Social Research at the University of Michigan in 1994. Of the nationally representative, stratified sample of 699 units, 618 (88%) participated. Spearman correlation, analysis of variance, Behrens-Fisher t-tests, and chi-square were used for bivariate comparisons. Culturally competent units are typically public, federal-funded organizations. Staffs of culturally competent units are typically college-educated with specialized treatment certification. High severity of illness as well as increased social distresses is pervasive among the clients of culturally competent units. Consideration of this client profile may be a key determinant in evaluating the effectiveness of cultural competency for African American substance abusers.

Are the treatment goals of culturally competent outpatient substance abuse treatment units congruent with their client profile?

This study examines whether organizational treatment goals varied among outpatient substance abuse treatment (OSAT) units identified as providing a level of culturally competent care for African Americans. Cross-sectional data from the 1995 National Drug Abuse Treatment System Survey (NDATSS) was used. Of the nationally representative, stratified sample of 699 units, 618 (88%) participated. Spearman correlation, analysis of variance, Behrens-Fisher t-tests, chi-square, and multivariate logistic regression were used. Culturally competent units, even after controlling for organizational and client characteristics, were more apt than non-culturally competent units to indicate that achieving steady employment, spiritual strength, and physical health were important treatment goals. A congruency exists among culturally competent OSAT units between the client profile, which is more distressful than that for non-culturally competent units, and the orientation of treatment goals, which are more holistic; that is, treating the total individual, rather than the addiction only.
