Smoking Prevalence in Addiction Treatment: A Review

Joseph Guydish; Emma Passalacqua; Barbara Tajima; Mable Chan; JongSerl Chun; Alan Bostrom

INTRODUCTION This review explores whether smoking prevalence in addiction treatment samples exceeds that shown in epidemiological data for persons with alcohol or other drug use disorders and whether smoking may have decreased over time in the addiction treatment population as it has done in the general population. METHODS English language papers published between 1987 and 2009 were searched electronically. Forty papers reporting smoking prevalence for addiction treatment samples in the United States were identified, and key predictor variables were abstracted. Random logistic models were used to assess relationships between each individual predictor (year, treatment modality, primary drug treated, government status, and public/private funding status) and smoking prevalence. RESULTS The lowest smoking prevalence aggregated for studies reported in any single year was 65%, well above epidemiological estimates reported among those with alcohol use and drug use disorders. The odds of smoking were higher in methadone maintenance programs (odds ratio [OR] = 2.25, CI = 1.08, 4.68) as compared with outpatient programs. No other variables in the model were significant. Reanalysis omitting recent studies that may represent outliers or confounding with type of treatment showed a small but significant decrease in smoking over time (OR = 0.9891, CI = 0.9888, 0.9893). CONCLUSIONS The very high smoking rates reported in addiction treatment samples warrant significant, organized, and systemic response from addiction treatment systems, from agencies that fund and regulate those systems, and from agencies concerned with tobacco control.

Staff Smoking and Other Barriers to Nicotine Dependence Intervention in Addiction Treatment Settings : A Review

Joseph Guydish; Emma Passalacqua; Barbara Tajima; Sarah Turcotte Manser

Abstract The aims of this review were to assess smoking prevalence among drug abuse treatment staff and summarize the range of barriers to provision of nicotine dependence intervention to clients receiving addictions treatment. A systematic literature search was conducted to identify publications reporting on workforce smoking prevalence, attitudes toward smoking, and perceived barriers to providing smoking cessation treatment in drug abuse treatment settings. Twenty papers met study inclusion criteria. Staff smoking prevalence estimates in the literature ranged from 14% to 40%. The most frequently reported barriers to providing nicotine dependence intervention in addiction treatment settings were lack of staff knowledge or training in this area, that smoking cessation concurrent with other drug or alcohol treatment may create a risk to sobriety, and staff are themselves smokers. Staff smoking is not uniformly elevated in the drug abuse treatment workforce. Smoking prevalence may be lower where staff are more educated or professionally trained, and may be higher in community-based drug treatment programs. Barriers to treating nicotine dependence may be addressed through staff training, policy development, and by supporting staff to quit smoking. State departments of alcohol and drug programs, and national and professional organizations, can also support treatment of nicotine dependence in drug abuse treatment settings.

AIMS Smoking prevalence is higher among people enrolled in addiction treatment compared with the general population, and very high rates of smoking are associated with opiate drug use and receipt of opiate replacement therapy (ORT). We assessed whether these findings are observed internationally. METHODS PubMed, PsycINFO and the Alcohol and Alcohol Problems Science Database were searched for papers reporting smoking prevalence among addiction treatment samples, published in English, from 1987 to 2013. Search terms included tobacco use, cessation and substance use disorders using and/or Boolean connectors. For 4549 papers identified, abstracts were reviewed by multiple raters; 239 abstracts met inclusion criteria and these full papers were reviewed for exclusion. Fifty-four studies, collectively comprising 37,364 participants, were included. For each paper we extracted country, author, year, sample size and gender, treatment modality, primary drug treated and smoking prevalence. RESULTS The random-effect pooled estimate of smoking across people in addiction treatment was 84% [confidence interval (CI) = 79, 88%], while the pooled estimate of smoking prevalence across matched population samples was 31% (CI = 29, 33%). The difference in the pooled estimates was 52% (CI = 48%, 57%, P < .0001). Smoking rates were higher in programs treating opiate use compared with alcohol use [odds ratio (OR) = 2.52, CI = 2.00, 3.17], and higher in ORT compared to out-patient programs (OR = 1.42, CI = 1.19, 1.68). CONCLUSIONS Smoking rates among people in addiction treatment are more than double those of people with similar demographic characteristics. Smoking rates are also higher in people being treated for opiate dependence compared with people being treated for alcohol use disorder.

BACKGROUND Smoking prevalence among persons in addiction treatment is 3-4 times higher than in the general population. However, treatment programs often report organizational barriers to providing tobacco-related services. This study assessed the effectiveness of a six month organizational change intervention, Addressing Tobacco Through Organizational Change (ATTOC), to improve how programs address tobacco dependence. METHODS The ATTOC intervention, implemented in three residential treatment programs, included consultation, staff training, policy development, leadership support and access to nicotine replacement therapy (NRT) medication. Program staff and clients were surveyed at pre- and post-intervention, and at 6 month follow-up. The staff survey measured knowledge of the hazards of smoking, attitudes about and barriers to treating smoking, counselor self-efficacy in providing such services, and practices used to address tobacco. The client survey measured knowledge, attitudes, and tobacco-related services received. NRT use was tracked. RESULTS From pre- to post-intervention, staff beliefs became more favorable toward treating tobacco dependence (F(1, 163)=7.15, p=0.008), NRT use increased, and tobacco-related practices increased in a non-significant trend (F(1, 123)=3.66, p=0.058). Client attitudes toward treating tobacco dependence became more favorable (F(1, 235)=10.58, p=0.0013) and clients received more tobacco-related services from their program (F(1, 235)=92.86, p<0.0001) and from their counselors (F(1, 235)=61.59, p<0.0001). Most changes remained at follow-up. CONCLUSIONS The ATTOC intervention can help shift the treatment system culture and increase tobacco services in addiction treatment programs.

Drug Court Effectiveness: A Review of California Evaluation Reports, 1995-1999

Joseph Guydish; Ellen Wolfe; Barbara Tajima; William J. Woods

Abstract Over the past two decades, drug courts have emerged as a viable alternative for addressing drug cases within the criminal justice system. In California, the Drug Court Partnership Program (DCPP) was created in 1998 and has supported and funded the development of drug courts throughout the State. This article reports on a review of California drug court evaluations through January 2000 conducted as part of an evaluation of the California DCPP. A total of 23 evaluations were collected. Seventeen were reviewed in detail, and six were excluded because they were internal reports rather than evaluations. A standardized review process was initiated which led to a scored rating of the evaluation reports. Results of this review support previous findings that drug court participants may experience reduced rearrest rates by 11% to 14% compared to nonparticipants. The largest reduction in rearrest rates appears among graduates. The graduation rates were between 19% and 54%. Costs and savings associated with drug courts were discussed but no conclusions were possible based on the findings from these evaluations. The evaluation of the effectiveness of drug courts presents unique challenges. This review concludes with a discussion of evaluation methods (e.g. standardizing rate calculations, term definitions) that would strengthen drug court research.

Development of the Smoking Knowledge, Attitudes, and Practices (S-KAP) Instrument.

Kevin Delucchi; Barbara Tajima; Joseph Guydish

This report describes the development and measurement characteristics of a new measure of smoking knowledge, attitudes, and practices (S-KAP) among treatment providers. Data are based on survey responses from 336 paid staff working in one of three drug abuse treatment or HIV care settings. Exploratory factor analysis, used to examine the factor structure, pointed towards five underlying factors: a single “knowledge” factor, three “attitude” factors (‘treatment barriers,’ ‘counselor self-efficacy,’ and ‘counselor attitudes’) and a single “practices” factor. The Knowledge scale had a standardized Cronbachs alpha coefficient of .85. The coefficients for Barriers, Self-Efficacy, and Attitudes were .81, .72, and .74, respectively. The Practice scale had a standardized Cronbachs alpha coefficient of .91. These results indicate that the proposed scales have reasonably good psychometric characteristics and will allow researchers to quantify staff knowledge, attitudes, and practices regarding smoking cessation treatments and issues.

Client Satisfaction with Drug Abuse Day Treatment versus Residential Care

Monica Chan; James L. Sorensen; Joseph Guydish; Barbara Tajima; Alfonso Acampora

We compared overall treatment satisfaction and helpfulness of treatment components for 216 clients randomly assigned to day versus residential treatment. Baseline interviews were conducted near admission using the Addiction Severity Index, Beck Depression Inventory, Symptom Check-list-90-R, and a social support measure. Follow-up interviews occurred 6 months later with these instruments plus a client satisfaction measure. Clients in both day and residential treatment were highly satisfied with overall services and most treatment components. Satisfaction scores were high and did not differ between modalities; however, mental health services were less helpful to day treatment clients, and more day treatment clients indicated not receiving certain treatment components. Client satisfaction correlated with treatment retention and several baseline and 6-month severity outcomes. These findings indicate day treatment may be as satisfying to clients as residential treatment, and give credence to the idea that client satisfaction assessment should be routine in outcome evaluations of drug abuse treatment.

Staff Knowledge, Attitudes, and Practices regarding Nicotine Dependence Differ by Setting

Barbara Tajima; Joseph Guydish; Kevin Delucchi; Emma Passalacqua; Mable Chan; Matt Moore

This study examined smoking-related knowledge, beliefs, self-efficacy, smoking cessation practices, and barriers to providing smoking cessation services in a workforce sample. The 11 participating clinics (N=335 staff) included substance abuse treatment and HIV care clinics categorized into three types: Veterans Affairs Medical Center (VAMC) clinics, hospital-based clinics, and community-based clinics. Staff in both VAMC and hospital-based settings shared characteristics that may predict smoking-related knowledge, beliefs, and practices (higher education level, low smoking rates, fewer staff in recovery, and location in hospital-affiliated environments where there was greater emphasis on physical health). However, staff in VAMC settings outperformed those in both hospital-based and community-based clinic settings on measures of smoking-related knowledge, beliefs, self-efficacy, and practices. Well-developed procedures to support VAMC clinicians in addressing smoking may account for these findings. Findings suggest that both reductions in staff smoking, and development and implementation of smoking policy are needed to support staff in better addressing nicotine dependence in community-based treatment settings.

Perspectives on the Drug Court Model Across Systems: A Process Evaluation

Ellen Wolfe; Joseph Guydish; William J. Woods; Barbara Tajima

Abstract Drug courts have been in existence since 1989, yet few process evaluations have appeared in the literature to help inform the discussion about their effectiveness. This article reports findings from a process evaluation of a drug court program in San Mateo, California. The evaluation was designed to document the history of the program, to examine program strengths and areas of improvement, to assess the roles and relationships among the various agencies involved and to describe the impact of the drug court on the justice and drug treatment systems. Methods included review of available drug court program documents, interviews with key stakeholders, and focus groups with drug court participants. The main findings were: support for the continuation of drug court, enhanced collaboration among all agencies, and an increased awareness of the needs of substance-using clients in the criminal justice system. Potential lessons for other drug courts include the importance of building strong collaborations and maintaining good communication, recognizing competing interests in developing procedures for drug court, and considering changes in eligibility criteria as experience with the drug court model expands.

Barriers and Facilitators to Tobacco Cessation in a Nationwide Sample of Addiction Treatment Programs

Anna Pagano; Barbara Tajima; Joseph Guydish

INTRODUCTION Smoking rates among addiction treatment clients are 3-4 times higher than those of the general population. Recent studies indicate that ceasing tobacco use during treatment may improve recovery outcomes. Across the United States, publicly funded addiction treatment programs vary widely in terms of their tobacco policies and tobacco cessation services offered to clients. METHODS The study reported here is the qualitative component of a larger study. Twenty-four programs were recruited from a random sample of publicly funded programs participating in the NIDA Clinical Trials Network. Semi-structured interviews were administered by phone to program directors. ATLAS.ti software was used to facilitate thematic analysis of interview transcripts. FINDINGS While all directors expressed interest in helping clients to quit smoking, they cited numerous barriers to implementing tobacco policies and services. These included smoking culture, client resistance, lack of resources, staff smoking, and environmental barriers. Directors also cited several factors that they believed would support tobacco cessation. These included financial support, enhanced leadership, and state mandates against smoking in addiction treatment programs. CONCLUSION Addiction treatment programs are beginning to place more emphasis on tobacco cessation during treatment. However, furthering this goal requires substantial infrastructural and cultural change. These qualitative study findings may help to inform Single State Agencies (SSAs) to support publicly funded addiction treatment programs in their tobacco cessation efforts. In order to maximize effectiveness, state-level policies regarding tobacco cessation during treatment should be informed by ongoing dialogue between service providers and SSAs.
