Addressing the Spectrum of Opioid Misuse Prevention, Treatment, and Recovery in Rural Washington State Communities: Provider Identified Barriers and Needs

The opioid overdose epidemic has significantly impacted rural communities. Rural settings present unique challenges to addressing opioid misuse. The purpose of the current study was to understand the similarities and differences between rural and urban-based providers serving rural communities. Washington state-based opioid-related service providers who serve rural communities (N = 75) completed an online survey between July and September 2020. Chi-square tests of association were used to examine significant differences in proportions between rural providers and rural-serving urban providers across opioid prevention, treatment, and recovery training topics. Rural providers reported receiving significantly less opioid treatment and recovery training on the criminal legal system, workplace-based education on treatment and recovery, and co-occurring disorder treatment; and significantly higher prior opioid prevention training on the prevention programs for youth and accessing prevention funding. Differences between rural and rural-serving urban providers demonstrate ways in which rural-urban partnerships can be strengthened to enhance public health.

Optimizing Contingency Management with Reinforcement Learning

Contingency Management (CM) is a psychological treatment that aims to change behavior with financial incentives. In substance use disorders (SUDs), deployment of CM has been enriched by longstanding discussions around the cost-effectiveness of prized-based and voucher-based approaches. In prize-based CM, participants earn draws to win prizes, including small incentives to reduce costs, and the number of draws escalates depending on the duration of maintenance of abstinence. In voucher-based CM, participants receive a predetermined voucher amount based on specific substance test results. While both types have enhanced treatment outcomes, there is room for improvement in their cost-effectiveness: the voucher-based system requires enduring financial investment; the prize-based system might sacrifice efficacy. Previous work in computational psychiatry of SUDs typically employs frameworks wherein participants make decisions to maximize their expected compensation. In contrast, we developed new frameworks that clinical decision-makers choose actions, CM structures, to reinforce the substance abstinence behavior of participants. We consider the choice of the voucher or prize to be a sequential decision, where there are two pivotal parameters: the prize probability for each draw and the escalation rule determining the number of draws. Recent advancements in Reinforcement Learning, more specifically, in off-policy evaluation, afforded techniques to estimate outcomes for different CM decision scenarios from observed clinical trial data. We searched CM schemas that maximized treatment outcomes with budget constraints. Using this framework, we analyzed data from the Clinical Trials Network to construct unbiased estimators on the effects of new CM schemas. Our results indicated that the optimal CM schema would be to strengthen reinforcement rapidly in the middle of the treatment course. Our estimated optimal CM policy improved treatment outcomes by 32% while maintaining costs. Our methods and results have broad applications in future clinical trial planning and translational investigations on the neurobiological basis of SUDs.

The urgent need for contingency management among Tribal communities in the United States: Considerations for implementation, policy, and sovereignty

In two randomized controlled trials, culturally adapted contingency management (i.e., incentives provided for substance-negative urine samples) was associated with reduced alcohol and drug use among geographically diverse American Indian and Alaska Native (AI/AN) adults. In response to interest in contingency management from other Tribal and AI/AN communities, our research team in collaboration with AI/AN behavioral health experts, translated the research into practice with new AI/AN community partners. Tenets of community-based participatory research were applied to develop, pilot, and refine contingency management training and implementation tools, and identify implementation challenges. In partnership with the AI/AN communities, four members of the university team developed tools and identified implementation and policy strategies to increase the successful uptake of contingency management in each location. Through our collaborative work, we identified policy barriers including inadequate federal funding of contingency management incentives and a need for further clarity regarding federal anti-kickback regulations. Adoption of contingency management is feasible and can strengthen Tribal communities' capacity to deliver evidence-based substance use disorder treatments to AI/AN people. Unfortunately, non-evidence-based limits to the use of federal funding for contingency management incentives discriminate against AI/AN communities. We recommend specific federal policy reforms, as well as other practical solutions for Tribal communities interested in contingency management.

Factors Associated with Child Removal Among American Indian and Alaska Native People in an Alcohol Intervention Study

This study was a secondary data analysis of factors associated with alcohol-related child removal among American Indian/Alaska Native (AI/AN) adults enrolled in a clinical trial of an alcohol intervention. Among 326 parent participants, 40% reported ever having a child removed from their care in part because of the parent's alcohol use, defined here as alcohol-related child removal. Seventy-five percent of parents reported at least one separation during their own childhood (M = 1.3, SD = 1.0). In a multivariable analysis, alcohol-related child removal was associated with parental boarding school attendance. No relationship was found between alcohol-related child removal and alcohol intervention outcomes. Results may provide evidence of multigenerational child removal impacts of boarding schools on AI/AN adults receiving an alcohol use disorder intervention. Assessment of parental history of child removal by practitioners, strategies to prevent alcohol-related separation and to support reunification should be integrated into addiction treatment in AI/AN communities.

Exploring the mediating role of baseline urinalysis results on demographic characteristics and stimulant use disorder treatment outcomes

INTRODUCTION

Baseline stimulant urinalysis (UA) is one of the most reliable predictors of stimulant use disorder treatment outcomes. Yet we know little about the role of baseline stimulant UA mediating the effects of different baseline characteristics on treatment outcomes.

OBJECTIVES

This study aimed to explore the potential mediating role of baseline stimulant UA results on the relationship between baseline characteristics and total number of stimulant negative UAs submitted during treatment.

METHODS

The study team conducted analyses on data from a multisite randomized clinical trial of contingency management (CM) targeting stimulant use among individuals enrolled in methadone maintenance treatment programs (n = 394). Baseline characteristics included trial arm, education, race, sex, age, and Addiction Severity Index (ASI) composite measures. Baseline stimulant UA was the mediator and total number of stimulant negative UAs provided during treatment was the primary outcome variable.

RESULTS

The baseline characteristics of sex (OR = 1.85), ASI drug (OR = 0.01) and psychiatric (OR = 6.20) composites were directly associated with the baseline stimulant UA result (p < 0.05 for all). Baseline stimulant UA result (B = -8.24), trial arm (B = -2.55), ASI drug composite (B = -8.38) and education (B = -1.95) were directly associated with the total number of negative UAs submitted (p < 0.05 for all). The evaluation of indirect effects of baseline characteristics on the primary outcome through baseline stimulant UA revealed significant mediated effects for the ASI drug composite (B = -5.50) and age (B = -0.05; p < 0.05 for both).

CONCLUSIONS

Baseline stimulant UA is a strong predictor of stimulant use treatment outcomes and mediates the association of some baseline characteristics and a stimulant use treatment outcome.

The Importance of Research Experience With a Scoreless Step 1: A Student Survey at a Community-Based Medical School

PURPOSE

As of January 26, 2022, the United States Medical Licensing Examination (USLME) step 1 exam went from a scored test to pass-fail step 1 (PFS1). The authors were interested in surveying medical students at a community-based medical school to observe their perceptions of the importance of student research given this recent change.

METHOD

A Qualtrics survey was disseminated to medical students (years 1-4) via school emails. Data were analyzed using the Mann-Whitney test to assess Likert scale scores, and narrative comments were grouped as qualitative feedback. Survey dissemination and analysis of data were both conducted at a large community-based medical school.

RESULTS

The survey sampled 104 students categorized into pre-clerkship (PC) and clerkship (CL) years, with a response rate of 33%. A contradiction was found, as indicated by the higher number (p = 0.047) of clerkship students interested in Primary Care/Family medicine residency compared to pre-clerkship students at 41% and 59%, respectively. Whereas participants who indicated they are interested in pursuing a competitive specialty for residency were 51% of pre-clerkship students over 41% of clerkship students (p = 0.047). Additionally, given the assessment change to pass/fail, students did in fact believe that residencies would now view research as a higher assessed component than before (79% pre-clerkship and 72% clerkship). However, a minority of students said that they increased their research efforts (41% and 47%). Most students supported the research opportunity improvements proposed in our survey.

CONCLUSIONS

Efforts to make the step 1 exam pass/fail may have alleviated some stress related to performance but may have increased the perception of the importance of other components in a student's residency application. Our survey highlights how medical students at a community-based medical school perceive this change and how it has affected their research efforts.

Investigating Secondary Alcohol Outcomes in a Contingency Management Intervention among American Indian and Alaska Native Adults

OBJECTIVE

The aim of the study is to investigate clinically meaningful, secondary outcomes in a randomized trial of a culturally adapted contingency management (CM) intervention for alcohol use in 3 diverse American Indian and Alaska Native communities.

METHODS

Three American Indian and Alaska Native communities located in the Northern Plains, Alaska, and the Inland Northwest were partnering sites. A total of 158 individuals were randomized to either a 12-week CM intervention or a noncontingent (NC) control group. The CM group received reinforcers for providing alcohol-negative ethyl glucuronide (EtG < 150 ng/mL) urine samples, while the NC group received reinforcers unconditionally. Outcomes included EtG as a continuous measure (range, 0-2,000 ng/mL), EtG > 499 ng/mL (a measure of higher levels of recent alcohol use), longest duration of abstinence, and time-to-first alcohol-positive EtG during the trial. Generalized estimating equations along with Cox proportional hazard and negative binomial regressions were used.

RESULTS

Participants randomized to the CM group had lower mean EtG levels (-241.9 ng/mL; 95% confidence interval [CI], -379.0 to -104.8 ng/mL) and 45.7% lower odds (95% CI, 0.31 to 0.95) of providing an EtG sample indicating higher levels of alcohol use during the intervention. Longest duration of abstinence was 43% longer for the CM group than the NC group (95% CI, 1.0 to 1.9). Risk of time-to-first drink during treatment did not differ significantly.

CONCLUSIONS

These secondary outcome analyses provide evidence that CM is associated with reductions in alcohol use and longer durations of abstinence (as assessed by EtG), both clinically meaningful endpoints and analyses that differ from the primary study outcome.

Contingency management for alcohol use disorder reduces cannabis use among American Indian and Alaska Native adults

OBJECTIVE

Determine whether a culturally tailored contingency management (CM) intervention targeting alcohol abstinence resulted in secondary effects on cannabis use among American Indian and Alaska Native (AI/AN) adults.

METHODS

The research team conducted this secondary data analysis to examine cannabis abstinence using data from a randomized control trial of CM for alcohol use among three AI/AN-serving organizations. One hundred and fifty-eight adults met the randomization criteria (i.e., submission of 50% or more urine samples and one alcohol-positive urine test during a 4-week, pre-randomization, observation period). For 12 weeks after randomization, participants received incentives for submitting a urine test negative for ethyl glucuronide (EtG < 150 ng/mL, CM group) or incentives for submitting a urine sample regardless of abstinence (Non-contingent [NC] Control group). Generalized linear mixed effects models assessed group differences in cannabis abstinence during the intervention, verified by urine tetrahydrocannabinol negative tests (11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid <50 ng/mL).

RESULTS

At baseline, 42.2% (n = 35) of participants in the NC group and 40.0% (n = 30) of those in the CM group had a cannabis positive urine test. An overall intervention by time interaction was detected for a cannabis negative urine test (χ2 = 13.40, p = 0.001). Compared to the NC group, the CM group had 3.92 (95% CI:1.23-12.46) times higher odds of having a cannabis negative urine test during the intervention period and 5.13 (95% CI:1.57-16.76) times higher odds of having a negative cannabis test at the end of intervention period.

CONCLUSION

CM addressing alcohol misuse may be an effective strategy for decreasing cannabis use among AI/AN adults.

Youth risk profiles and their prediction of distal cannabis and tobacco co-use in the Population Assessment of Tobacco Health (PATH)

Background: Co-use of cannabis and tobacco is common and increases negative behavioral, physical and mental health consequences. This study aimed to describe latent profiles of youth internalizing and externalizing problems, sensation seeking, and family environment in the US and their relationships with substance co-use. Methods: Data come from the Population Assessment of Tobacco Health (PATH). Using latent profile analysis with a distal outcome, we conducted a secondary data analysis examining relationships between latent profiles and the distal outcome of cannabis/tobacco use and co-use one year later. Participants were a nationally representative sample of youth ages 12-17 (N = 13,651). Results: We identified five youth subgroups: (1;11%) Family Risk, (2;32%) Family Protection with Very Low Internalizing, (3;21%) Family Protection with High Youth Risk, (4;24%) Family Protection with Moderate Youth Risk, (5;12%) Family Risk with High Youth Risk. Relationships between group membership and tobacco/cannabis outcomes, one year later, indicated that the least likely tobacco/cannabis users were the Family Protection with Very Low Internalizing class (no lifetime use probability (PR)=0.86, standard error (SE)=0.007; no 30-day use PR = 0.96, SE = 0.004). In contrast, the Family Risk with High Youth Risk class had the highest probability of both co-use (lifetime co-use PR = 0.33; SE = 0.014; 30-day co-use PR = 0.10; SE = 0.010) and single substance use (probability of lifetime single substance use PR = 0.30; SE = 0.013; 30-day single substance use PR = 0.24; SE = 0.014). Conclusions: A "protective but reactive" risk buffering pattern effect of family factors on youth factors was observed in that the lowest rates of co-use were observed in the three classes with family protection. These findings highlight the need for interventions addressing multiple domains and focusing on youth and family risk factors.

Effect of Incentives for Alcohol Abstinence in Partnership With 3 American Indian and Alaska Native Communities: A Randomized Clinical Trial

Importance

Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders.

Objective

To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition.

Design, Setting, and Participants

This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020.

Interventions

Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period.

Main Outcomes and Measures

Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL).

Results

Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03).

Conclusions and Relevance

The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders.

Predictors of cannabis and tobacco co-use in youth: exploring the mediating role of age at first use in the population assessment of tobacco health (PATH) study

Background

Adolescents often use substances such as tobacco and cannabis. Co-use of these substances can lead to physical, mental, and psychosocial difficulties beyond that which would be anticipated by simple additivity of their individual effects.

Methods

We aimed to examine the mediating role of age at first use of cannabis or tobacco (AU) between youth factors of internalizing, externalizing, and sensation seeking and two co-use outcomes (lifetime; last 30 days). Path analytic modeling using data from youth age 12–17 who had tried cannabis or tobacco at least once in their lives and participated in the Population Assessment of Tobacco Health (PATH) waves one and two (collected 2013–2015; n=3,847; approximately 46% female) study allowed us to examine these relationships.

Results

The lifetime use model indicated significant direct (internalizing (B = 0.18), externalizing (B = 0.30), sensation seeking (B = 0.15)) and indirect relationships (internalizing (B = 0.18), externalizing (B = 0.33), sensation seeking (B = 0.10)) between each of the three youth factors, the mediator (AU) and the lifetime co-use outcome (p < 0.05 for all). A direct relationship between AU and lifetime co-use was also observed (B = − 1.54). In the past 30-day use model, significant direct paths from AU (B = − 0.49) and sensation seeking (B = 0.06) to past 30-day use were present (p < 0.05 for all).

Discussion

Examination of mediation by AU in the relationships between youth factors and youth co-use of cannabis and tobacco is an important step in understanding these complex relationships. This study is strengthened by the use of a large, nationally representative sample, yet is limited by several factors, such as the use of a secondary dataset and the use of youth self-report.

Conclusions

Based on the findings, programs or interventions targeting youth factors of internalizing, externalizing, and sensation seeking as well as interventions aiming to stave off AU should promote decreased tobacco and cannabis co-use. Sensation seeking and AU appear to be the most influential factors and should be considered when developing and promoting prevention policies/programs for higher risk youth populations.

Development and Implementation of a Mobile Tool for High-Risk Pregnant Women to Deliver Effective Caregiving for Neonatal Abstinence Syndrome: Protocol for a Mixed Methods Study

Background

The United States continues to experience an alarming rise in opioid use that includes women who become pregnant and related neonatal abstinence syndrome (NAS) in newborns. Most newborns experiencing NAS require nonpharmacological care, which entails, most importantly, maternal involvement with the newborn. To facilitate positive maternal-newborn interactions, mothers need to learn effective caregiving NAS strategies when they are pregnant; however, an enormous gap exists in the early education of mothers on the symptoms and progression of NAS, partly because no education, training, or other interventions exist to prepare future mothers for the challenges of caring for their newborns at risk for NAS.

Objective

In this paper, we describe a mixed methods, multistage study to adapt an existing mobile NAS tool for high-risk pregnant women and assess its usability, acceptability, and feasibility in a small randomized controlled trial.

Methods

Stage 1 will include 20 semistructured interviews with a panel of neonatology experts, NAS care providers, and mothers with experience caring for NAS-affected newborns to gather their recommendations on the management of NAS and explore their perspectives on the care of these newborns. The findings will guide the adaptation of existing mobile NAS tools for high-risk pregnant women. In stage 2, we will test the usability, acceptability, and feasibility of the adapted mobile tool via surveys with 10 pregnant women receiving opioid agonist therapy (OAT). Finally, in stage 3, we will randomize 30 high-risk pregnant women receiving OAT to either receive the adapted mobile NAS caregiving tool or usual care. We will compare these women on primary outcomes—maternal drug relapse and OAT continuation—and secondary outcomes—maternal-newborn bonding; length of newborn hospital stays; readmission rates; breastfeeding initiation and duration; and postpartum depression and anxiety at 4, 8, and 12 weeks postpartum.

Results

This project was funded in July 2020 and approved by the institutional review board in April 2020. Data collection for stage 1 began in December 2020, and as of January 2021, we completed 18 semistructured interviews (10 with NAS providers and 8 with perinatal women receiving OAT). Common themes from all interviews will be analyzed in spring 2021 to inform the adaptation of the NAS caregiving tool. The results from stage 1 are expected to be published in summer 2021. Stage 2 data collection will commence in fall 2021.

Conclusions

The findings of this study have the potential to improve NAS care and maternal-newborn outcomes and lead to commercialized product development. If effective, our new tool will be well suited to tailoring for other high-risk perinatal women with substance use disorders.

The rewarding recovery study: a randomized controlled trial of incentives for alcohol and drug abstinence with a rural American Indian community

AIMS

To test if contingency management (CM) interventions for alcohol and drug abstinence were associated with increased alcohol and drug abstinence among American Indian adults with alcohol dependence who also use drugs.

DESIGN

In this 2 × 2 factorial randomized controlled trial, American Indian adults with alcohol dependence who also used drugs were randomized to four conditions: (1) incentives for submission of urine samples only (control condition), (2) CM incentives for alcohol abstinence, (3) CM incentives for drug abstinence or (4) CM incentives for abstinence from both alcohol and drugs.

SETTING

A Northern Plains Reservation in the United States.

PARTICIPANTS

A total of 114 American Indian adults aged 35.8 years (standard deviation = 10.4); 49.1% were male.

INTERVENTION AND COMPARATOR

Participants received incentives if they demonstrated abstinence from alcohol (CM for alcohol, n = 30), abstinence from their most frequently used drug (CM for drugs, n = 27) or abstinence from both alcohol and their most frequently used drug (CM for alcohol and drugs, n = 32) as assessed by urine tests. Controls (n = 25) received incentives for submitting urine samples only.

MEASUREMENTS

Primary outcomes were urine ethyl glucuronide (alcohol) and drug tests conducted three times per week during the 12-week intervention period. Data analyses included listwise deletion and multiple imputation to account for missing data.

FINDINGS

The three CM groups were significantly (P < 0.05) more likely to submit alcohol-abstinent urine samples compared with the control condition, with odds ratios ranging from 2.4 to 4.8. The CM for drugs (OR = 3.2) and CM for alcohol and drugs (OR = 2.5) were significantly more likely to submit urine samples that indicated drug abstinence, relative to the control condition (P < 0.05). However, these differences were not significant in multiple imputation analyses (P > 0.05).

CONCLUSIONS

Contingency management (CM) incentives for abstinence were associated with increased alcohol abstinence in American Indian adults diagnosed with alcohol dependence who also used drugs, living on a rural reservation. The effect of CM incentives on drug abstinence was inconclusive.

Contingency management is effective in promoting abstinence and retention in treatment among crack cocaine users with a previous history of poor treatment response: a crossover trial

BACKGROUND

Crack use has become a severe health problem in Brazil. Contingency management has shown robust evidence of efficacy in the treatment of cocaine use disorder (CUD) in high-income countries; however, it is still unclear how this intervention can impact treatment in low-income countries.

OBJECTIVE

To evaluate the efficacy of contingency management in the treatment of CUD among individuals with a previous history of poor treatment response in Brazil.

METHODS

Six months after the end of treatment, 32 participants previously allocated to the usual care condition (UCC) were invited to receive an additional 12 weeks of treatment in a contingency management condition (CMC), and 16 accepted the invitation. We compared data obtained from only the 16 participants (14 male) exposed to both treatment conditions.

RESULTS

Participants attended more treatment sessions and were retained in treatment for a longer period during the CMC than during the UCC (p < .01 for both). The proportion of negative cocaine samples submitted, the mean longest duration of cocaine abstinence, and the odds of being abstinent from cocaine during the 12 weeks of treatment were significantly higher during treatment in the CMC when compared to the UCC (p < .05).

CONCLUSIONS

This study provides further evidence that contingency management is effective in promoting abstinence and retention in treatment among individuals with CUD with a history of poor treatment response. Our findings argue for the incorporation of CM among public treatment services for CUD in Brazil.

Seeking Chronic Pain Relief: A Hermeneutic Exploration

BACKGROUND

In the United States, chronic pain is experienced by over 39.4 million adults, many of whom are treated with opioid pain medications.

AIM

This research presents an interpretation of the experience of seeking pain relief for a group of people taking opioid pain medications whose pain is not adequately controlled.

METHODS

A concurrent embedded mixed-methods design was used, including a Heideggerian hermeneutic qualitative approach that focuses on the participants' perceptions as a vehicle for understanding the phenomenon of seeking pain relief with descriptive quantitative data in a supporting role. Thirteen interviews and 15 surveys were analyzed, all of which met the following criteria: (1) self-reported chronic pain (persistent pain lasting a minimum of six months), (2) current use of prescription opioid medications, (3) pain not successfully controlled.

RESULTS

The analysis revealed a paradox, which we describe as being lost/finding myself in the health care system. This paradox became the overarching pattern of experience that subsumed several dynamic, overlapping practices described in the patterns: (1) seeking relief as suffering; (2) being classified as an addict but not an addict; (3) living with pain as remembering; and (4) experiencing treatment modalities as fickle possibilities.

CONCLUSION

Explication of and interpretive commentary on these patterns shift the focus from drug seeking to pain relief seeking behaviors in chronic pain sufferers. Such a shift could change the manner in which providers work with chronic pain sufferers to find appropriate treatment modalities.

Pilot investigation of a phosphatidylethanol-based contingency management intervention targeting alcohol use

Phosphatidylethanol (PEth) can be detected in blood from 14 to as many as 28 days after alcohol consumption, depending on the amount and frequency of alcohol consumed. PEth may have utility for verifying abstinence in a contingency management (CM) intervention for alcohol use, particularly in settings where frequent verification of abstinence is impossible or impractical. Five nontreatment-seeking heavy drinkers (40% men) participated in an 11-week, ABA-phased within-subject experiment for which they submitted blood spots for PEth measurement, urine samples for ethyl glucuronide (EtG) testing, and self-report drinking data weekly. Participants received reinforcers for submitting samples throughout the A phases. During the B phase (CM phase), they received additional reinforcers when their PEth level was reduced from the previous week and was verified by a negative EtG (<150 ng/ml) urine test and self-report. PEth, EtG, and self-report outcomes were compared between A phases (Weeks 1-3, 8-11) and B phases (Weeks 4-7). During the A phases, 23% of PEth results indicated alcohol abstinence, whereas 53% of PEth samples submitted during the CM (B phase) indicated alcohol abstinence. Participants were more likely to submit EtG-negative urine samples and report lower levels of drinking and heavy drinking during the B phase, relative to the A phases. We also explored the ability of PEth to detect self-reported drinking. The combined PEth homologs (16:0/18:1 and 16:0/18:2) predicted self-reported drinking with area under the curve from 0.81 (1 week) to 0.80 (3 weeks). Results support the initial feasibility of a Peth-based CM intervention. (PsycINFO Database Record

A Randomized Controlled Trial of a Citywide Emergency Department Care-Coordination Program to Reduce Prescription Opioid-Related Visits: An Economic Evaluation

BACKGROUND

Care provided in the emergency department (ED) can cost up to five times as much as care received for comparable diagnoses in alternative settings. Small groups of patients, many of whom suffer from an opioid use disorder, often account for a large proportion of total ED visits. We recently conducted, and demonstrated the effectiveness of, the first randomized controlled trial of a citywide ED care-coordination program intending to reduce prescription-opioid-related ED visits. All EDs in the metropolitan study area were connected to a Web-based information exchange system.

OBJECTIVE

The objective of this article was to perform an economic evaluation of the 12-month trial from a third-party-payer perspective.

METHODS

We modeled the person-period monthly for the 12-month observation period, and estimated total treatment costs and return on investment (ROI) with regard to cost offsets, over time, for all visits where the patient was admitted to and discharged from the ED.

RESULTS

By the end of month 4, the mean cumulative cost differential was significantly lower for intervention relative to treatment-as-usual participants (-$1370; p = 0.03); this figure climbed to -$3200 (p = 0.02) by the end of month 12. The ROI trended upward throughout the observation period, but failed to reach statistical significance by the end of month 12 (ROI = 3.39, p = 0.07).

CONCLUSION

The intervention produced significant cost offsets by the end of month 4, which continued to accumulate throughout the trial; however, ROI was not significant. Because the per-patient administrative costs of the program are incurred at the time of enrollment, our results highlight the importance of future studies that are able to follow participants for a period beyond 12 months to more accurately estimate the program's ROI.

Use of cell phones and computers for health promotion and tobacco cessation by American Indian college students in Montana

INTRODUCTION

Cell phones and personal computers have become popular mechanisms for delivering and monitoring health information and education, including the delivery of tobacco cessation education and support. Tobacco smoking is prevalent among American Indians (AIs) and Alaska Natives (ANs), with 26% AI/AN adult men smoking compared to 19% of Caucasian adult males and 22% of African American adult males. Smoking is even more prevalent in Northern Plains AI populations, with 42% of men <i>and</i> women reporting current smoking. The literature on the availability and use of cell phones and computers, or the acceptability of use in health promotion among AIs and ANs, is scant. The authors report findings from a survey of AI students regarding their cell phone and computer access and use. The survey was conducted to inform the development and implementation of a text messaging smoking cessation intervention modeled on a program developed and used in Australia.

METHODS

A 22-item paper and pencil survey was administered to students at tribal colleges in rural Montana. The survey questions included cell phone ownership and access to service, use of cell phones and computers for health information, demographics, tobacco use habits, and interest in an intervention study. The study was reviewed and determined exempt by the institutional review boards at the tribal colleges and the lead research university. The study was conducted by researchers at the tribal colleges. Survey respondents received $10 when the survey was completed and returned. Data analysis was performed with the Statistical Package for the Social Sciences.

RESULTS

Among 153 AI respondents, the mean age was 29 years, range was 18-64 years. Overall, 40% reported smoking cigarettes with a mean age of 16 years at initiation. A total of 131 participants (86%) had cell phones and, of those, 122 (93%) had unlimited text messaging. A total of 104 (68%) had smart phones (with internet access), although 40% of those with smart phones reported that internet access on their phone was very slow or location limited. A total of 146 (95%) participants reported having access to a computer, although 32% of those did not have daily access. Students aged less than 23 years were more likely to have cell phones with internet access. Cell phone ownership differed by site (93% vs 77%,<i> p</i>=0.007). About 60% of the respondents who smoked indicated interest in participating in the intervention study.

CONCLUSIONS

This study revealed that<b> </b>AI<b> </b>tribal college students in the rural communities surveyed had less<b> </b>cell phone, smart phone, and computer and internet access than that reported for undergraduate college students elsewhere in the USA.<b> </b>Research efforts and public health interventions must be culturally appropriate and technologically viable, therefore access to and acceptability of mobile technology must be evaluated when planning and implementing interventions for rural and other marginalized populations. The findings from this study contribute to the literature regarding the access to and acceptability of mobile technology for health promotion among AI/AN college students in rural and remote areas, and helped introduce the proposed study to the community and solicited useful data regarding tobacco prevalence and interest in tobacco research in the target population.

A Randomized Controlled Trial of a Citywide Emergency Department Care Coordination Program to Reduce Prescription Opioid Related Emergency Department Visits

BACKGROUND

Increasing prescription overdose deaths have demonstrated the need for safer emergency department (ED) prescribing practices for patients who are frequent ED users.

OBJECTIVES

We hypothesized that the care of frequent ED users would improve using a citywide care coordination program combined with an ED care coordination information system, as measured by fewer ED visits by and decreased controlled substance prescribing to these patients.

METHODS

We conducted a multisite randomized controlled trial (RCT) across all EDs in a metropolitan area; 165 patients with the most ED visits for complaints of pain were randomized. For the treatment arm, drivers of ED use were identified by medical record review. Patients and their primary care providers were contacted by phone. Each patient was discussed at a community multidisciplinary meeting where recommendations for ED care were formed. The ED care recommendations were stored in an ED information exchange system that faxed them to the treating ED provider when the patient presented to the ED. The control arm was subjected to treatment as usual.

RESULTS

The intervention arm experienced a 34% decrease (incident rate ratios = 0.66, p < 0.001; 95% confidence interval 0.57-0.78) in ED visits and an 80% decrease (odds ratio = 0.21, p = 0.001) in the odds of receiving an opioid prescription from the ED relative to the control group. Declines of 43.7%, 53.1%, 52.9%, and 53.1% were observed in the treatment group for morphine milligram equivalents, controlled substance pills, prescriptions, and prescribers, respectively.

CONCLUSION

This RCT showed the effectiveness of a citywide ED care coordination program in reducing ED visits and controlled substance prescribing.

Association Between Prescription Opioid Use and Biomarkers of Kidney Disease in US Adults

BACKGROUND/AIMS

Prescription opioid use is increasing despite concerns about drug safety. We examined relationships between use of analgesics with biomarkers of chronic kidney disease (CKD) in a representative sample of adults in the United States (US).

METHODS

Participants (n=3980) were from the National Health and Nutrition Examination Survey (NHANES) 2009-2010. Use of any analgesic, prescription opioids, and NSAIDs were compared to referent groups with use of non-analgesic prescription medication or use of no prescription medication. CKD biomarkers including urine albumin-to-creatinine ratio (UACR) and serum-creatinine-based estimated glomerular filtration rate (eGFR; CKD Epidemiology Collaboration: CKD-EPI equation) were analyzed as continuous and binary variables (UACR ≥30 mg/g or eGFR <60 mL/min per 1.73m2; median splits).

RESULTS

Frequencies of use were: any prescription analgesic 12.7% (507/3980); prescription opioids 5.1% (204/3980); NSAIDs 5.6% (224/3980); non-analgesic medication 38.7% (1540/3980); no medication 48.6% (1933/3980). Prescription analgesic use (β=0.17, p=0.021) and opioid use (β=0.19, p=0.002) were associated with higher UACR values, while NSAID use was not (β=0.17, p=0.105). Prescription analgesic use was related to UACR ≥5.98 mg/g (median), (OR=1.34, 95%CI=1.01-7.79, p=0.045). No type of analgesic use was related to CKD-EPI eGFR.

CONCLUSION

In a representative US population, prescription opioid use associated with higher albuminuria levels compared to non-opioid-users.

A culturally-tailored behavioral intervention trial for alcohol use disorders in three American Indian communities: Rationale, design, and methods

BACKGROUND

Disproportionately high rates of alcohol use disorders are present in many American Indian/Alaska Native (AI/AN) communities, yet little information exists regarding the effectiveness of alcohol treatments in AI/AN populations. Contingency management is an intervention for illicit drug use in which tangible reinforcers (rewards) are provided when patients demonstrate abstinence as assessed by urine drug tests. Contingency management has not been widely studied as an intervention for alcohol problems because until recently, no alcohol biomarker has been available to adequately verify abstinence.

AIMS

The HONOR Study is designed to determine whether a culturally-tailored contingency management intervention is an effective intervention for AI/AN adults who suffer from alcohol use disorders.

METHODS

Participants include 400 AI/AN alcohol-dependent adults residing in one rural reservation, one urban community, as well as a third site to be decided, in the Western U.S. Participants complete a 4-week lead-in phase prior to randomization, then 12 weeks of either a contingency management intervention for alcohol abstinence, or a control condition where participants receive reinforcers for attending study visits regardless of alcohol use. Participants are then followed for 3-more months post-intervention. The primary study outcome is urinary ethyl glucuronide-confirmed alcohol abstinence; secondary outcomes include self-reported alcohol and drug use, HIV risk behaviors, and self-reported cigarette smoking.

DISCUSSION

This will be the largest randomized, controlled trial of any alcohol for AI/ANs and the largest contingency management study targeting alcohol use disorders, thus providing important information to AI/AN communities and the alcohol treatment field in general.

An application of analyzing the trajectories of two disorders: A parallel piecewise growth model of substance use and attention-deficit/hyperactivity disorder

Researchers often want to examine 2 comorbid conditions simultaneously. One strategy to do so is through the use of parallel latent growth curve modeling (LGCM). This statistical technique allows for the simultaneous evaluation of 2 disorders to determine the explanations and predictors of change over time. Additionally, a piecewise model can help identify whether there are more than 2 growth processes within each disorder (e.g., during a clinical trial). A parallel piecewise LGCM was applied to self-reported attention-deficit/hyperactivity disorder (ADHD) and self-reported substance use symptoms in 303 adolescents enrolled in cognitive-behavioral therapy treatment for a substance use disorder and receiving either oral-methylphenidate or placebo for ADHD across 16 weeks. Assessing these 2 disorders concurrently allowed us to determine whether elevated levels of 1 disorder predicted elevated levels or increased risk of the other disorder. First, a piecewise growth model measured ADHD and substance use separately. Next, a parallel piecewise LGCM was used to estimate the regressions across disorders to determine whether higher scores at baseline of the disorders (i.e., ADHD or substance use disorder) predicted rates of change in the related disorder. Finally, treatment was added to the model to predict change. While the analyses revealed no significant relationships across disorders, this study explains and applies a parallel piecewise growth model to examine the developmental processes of comorbid conditions over the course of a clinical trial. Strengths of piecewise and parallel LGCMs for other addictions researchers interested in examining dual processes over time are discussed.

Using ethyl glucuronide in urine to detect light and heavy drinking in alcohol dependent outpatients

AIMS

This study investigated which ethyl glucuronide immunoassay (EtG-I) cutoff best detects heavy versus light drinking over five days in alcohol dependent outpatients.

METHODS

A total of 121 adults with alcohol use disorders and co-occurring psychiatric disorders took part in an alcohol treatment study. Participants provided self-reported drinking data and urine samples three times per week for 16-weeks (total samples=2761). Agreement between low (100 ng/mL, 200 ng/mL), and moderate (500 ng/mL) EtG-I cutoffs and light (women ≤3 standard drinks, men ≤4 standard drinks) and heavy drinking (women >3, men >4 standard drinks) were calculated over one to five days.

RESULTS

The 100 ng/mL cutoff detected >76% of light drinking for two days, and 66% at five days. The 100 ng/mL cutoff detected 84% (1 day) to 79% (5 days) of heavy drinking. The 200 ng/mL cutoff detected >55% of light drinking across five days and >66% of heavy drinking across five days. A 500 ng/mL cutoff identified 68% of light drinking and 78% of heavy drinking for one day, with detection of light (2-5 days <58%) and heavy drinking (2-5 days <71%) decreasing thereafter. Relative to 100 ng/mL, the 200 ng/mL and 500 ng/mL cutoffs were less likely to result in false positives.

CONCLUSIONS

An EtG-I cutoff of 100 ng/mL is most likely to detect heavy drinking for up to five days and any drinking during the previous two days. Cutoffs of ≥500 ng/mL are likely to only detect heavy drinking during the previous day.

Examining Longitudinal Stimulant Use and Treatment Attendance as Parallel Outcomes in Two Contingency Management Randomized Clinical Trials

The primary aim of this study was to examine stimulant use and longitudinal treatment attendance in one 'parallel outcomes' model in order to determine how these two outcomes are related to one another during treatment, and to quantify how the intervention impacts these two on- and off-target outcomes differently. Data came from two multi-site randomized clinical trials (RCTs) of contingency management (CM) that targeted stimulant use. We used parallel multilevel modeling to examine the impact of multiple pre-specified covariates, including selected Addiction Severity Index (ASI) scores, age and sex, in addition to CM on concurrent attendance and stimulant use in two separate analyses, i.e., one per trial. In one trial, CM was positively associated with attending treatment throughout the trial (β=0.060, p<0.05). In the second trial, CM predicted negative urinalysis ((-)UA) over the 12-week treatment period (β=0.069, p<0.05). In both trials, there was a significant, positive relationship between attendance and (-)UA submission, but in the first trial a (-)UA at both baseline and over time was related to attendance over time (r=0.117; r=0.013, respectively) and in the second trial, a (-)UA submission at baseline was associated with increased attendance over time (r=0.055). These findings indicate that stimulant use and treatment attendance over time are related but distinct outcomes that, when analyzed simultaneously, portray a more informative picture of their predictors and the separate trajectories of each. This 'indirect reinforcement' between two clinically meaningful on-target (directly reinforced behavior) and off-target (indirectly reinforced behavior) outcomes is in need of further examination in order to fully exploit the potential clinical benefits that could be realized in substance use disorder treatment trials.

Determining ethyl glucuronide cutoffs when detecting self-reported alcohol use in addiction treatment patients

BACKGROUND

Ethyl glucuronide (EtG) is an alcohol biomarker with potential utility as a clinical research and alcohol treatment outcome. Debate exists regarding the appropriate cutoff level for determining alcohol use, particularly with the EtG immunoassay. This study determined the EtG immunoassay cutoff levels that most closely correspond to self-reported drinking in alcohol-dependent outpatients.

METHODS

Eighty adults with alcohol dependence and mental illness, taking part in an alcohol treatment study, provided urine samples 3 times per week for up to 16 weeks (1,589 samples). Self-reported drinking during 120 hours prior to each sample collection was assessed. Receiver operating characteristic analyses were conducted to assess the ability of the EtG immunoassay to detect self-reported alcohol use across 24- to 120-hour time periods. Sensitivity and specificity of EtG immunoassay cutoff levels was compared in 100 ng/ml increments (100 to 500 ng/ml) across 24 to 120 hours.

RESULTS

Over half (57%) of the 1,589 samples indicated recent alcohol consumption. The EtG immunoassay closely corresponded to self-reported drinking from 24 (area under the curve [AUC] = 0.90, 95% confidence interval [CI]: 0.88, 0.92) to 120 hours (AUC = 0.88, 95% CI: 0.87, 0.90). When cutoff levels were compared across 24 to 120 hours, 100 ng/ml had the highest sensitivity (0.93 to 0.78) and lowest specificity (0.67 to 0.85). Relative to 100 ng/ml, the 200 ng/ml cutoff demonstrated a reduction in sensitivity (0.89 to 0.67), but improved specificity (0.78 to 0.94). The 300, 400, and 500 ng/ml cutoffs demonstrated the lowest sensitivity (0.86 to 0.33) and highest specificity (0.86 to 0.97) over 24 to 120 hours.

CONCLUSIONS

For detecting alcohol use for >24 hours, the 200 ng/ml cutoff level is recommended for use as a research and clinical outcome.

A 'missing not at random' (MNAR) and 'missing at random' (MAR) growth model comparison with a buprenorphine/naloxone clinical trial

AIMS

To compare three missing data strategies: (i) the latent growth model that assumes the data are missing at random (MAR) model; (ii) the Diggle-Kenward missing not at random (MNAR) model, where dropout is a function of previous/concurrent urinalysis (UA) submissions; and (iii) the Wu-Carroll MNAR model where dropout is a function of the growth factors. DESIGN : Secondary data analysis of a National Drug Abuse Treatment Clinical Trials Network trial that examined a 7-day versus 28-day taper (i.e. stepwise decrease in buprenorphine/naloxone) on the likelihood of submitting an opioid-positive UA during treatment.

SETTING

11 out-patient treatment settings in 10 US cities.

PARTICIPANTS

A total of 516 opioid-dependent participants.

MEASUREMENTS

Opioid UAs provided across the 4-week treatment period.

FINDINGS

The MAR model showed a significant effect (B = -0.45, P < 0.05) of trial arm on the opioid-positive UA slope (i.e. 28-day taper participants were less likely to submit a positive UA over time) with a small effect size (d = 0.20). The MNAR Diggle-Kenward model demonstrated a significant (B = -0.64, P < 0.01) effect of trial arm on the slope with a large effect size (d = 0.82). The MNAR Wu-Carroll model showed a significant (B = -0.41, P < 0.05) effect of trial arm on the UA slope that was relatively small (d = 0.31).

CONCLUSIONS

This performance comparison of three missing data strategies (latent growth model, Diggle-Kenward selection model, Wu-Carrol selection model) on sample data indicates a need for increased use of sensitivity analyses in clinical trial research. Given the potential sensitivity of the trial arm effect to missing data assumptions, it is critical for researchers to consider whether the assumptions associated with each model are defensible.

Young adult waterpipe smokers: Smoking behaviors and associated subjective and physiological effects

INTRODUCTION

The purpose of this pilot study was to investigate smoking behaviors and subjective and physiological effects of nicotine on young adult occasional waterpipe smokers.

METHODS

This study utilized a repeated-measures design that included one repeated factor for condition (nicotine and non-nicotine). For each participant, the sequencing of the repeated factor was assigned using random allocation. The two nicotine conditions were nicotine (0.75 g) and non-nicotine (0 g placebo) tobacco. Over the course of two weeks, twenty-two participants completed subjective (Acute Subjective Effects of Nicotine) and physiological (blood pressure, heart rate, and CO level) measures. Additional measures (QSU and MNWS-R) were used to assess for withdrawal symptoms.

SAMPLE

The participants (n=22) were young adults (23 ± 3.1years); 71% smoked waterpipe once a month in the past year and 29% smoked waterpipe 1-2 times per week. In addition, 60% reported sharing their waterpipe with friends while smoking. None of the participants reported using any other forms of tobacco products.

RESULTS

Under the nicotine condition, participants tended to smoke longer (i.e. smoking duration, p=0.004), take more puffs (p=0.03), take shorter puffs (p=0.03), and inhale less volume with each puff (p=0.02). The repeated measures analysis of the factor headrush revealed an effect of the nicotine condition (F=9.69, p<0.001, partial η(2)=0.31) and time (F=8.17, p=0.02, partial η(2)=0.30). Heart rate increased significantly across the nicotine condition (F=7.92, p=0.01, partial η(2)=0.31) and over time (F=12.64, p=0.01, partial η(2)=0.41).

CONCLUSIONS

This study demonstrates how differences between nicotine and non-nicotine waterpipe smoking are associated with changes in smoking behaviors, experiencing a headrush and an increase in heart rate.

Acceptability of contingency management among clinicians and clients within a co-occurring mental health and substance use treatment program

BACKGROUND

Emerging evidence supports the effectiveness of contingency management (CM) for addictions treatment among individuals with co-occurring serious mental illness (SMI). Addiction treatment for people with SMI generally occurs within community mental health centers (CMHCs) and it is not known whether CM is acceptable within this context. Client views regarding CM are also unknown.

OBJECTIVES

This study is the first to describe CM acceptability among CMHC clinicians, and the first to explore client views. Clinician-level predictors of CM acceptability are also examined.

METHODS

This study examined views about CM among 80 clinicians and 29 clients within a CMHC within the context of a concurrent CM study.

RESULTS

Three-quarters of clinicians reported they would use CM if funding were available. Clinicians and clients affirmed that incentives enhance abstinence motivation. Clinician CM acceptability was related to greater years of experience, and identifying as an addictions or co-occurring disorders counselor, more than a mental health clinician.

CONCLUSIONS

The findings provide preliminary evidence that CMHC clinicians, serving clients with addictions and complicating SMI, and client participants in CM, view CM as motivating and a positive tool to facilitate recovery.

SCIENTIFIC SIGNIFICANCE

As an evidence-based intervention, CM warrants further efforts toward funding and dissemination in CMHCs.

Association of co-occurring serious mental illness with emergency hospitalization in people with chronic kidney disease

BACKGROUND/AIMS

Chronic kidney disease (CKD) and serious mental illness (SMI) are both associated with an increased risk for repeated hospitalization. The objective of this study was to determine if co-occurring SMI exacerbates the risk for subsequent hospitalization, particularly through the emergency department (ED), among people with CKD.

METHODS

People hospitalized in Washington State from April 2006 to December 2008 were separated into cohorts with diagnoses of CKD (n = 31,166), SMI (defined by schizophrenia and/or mood disorder; n = 20,167) or CKD with co-occurring SMI (n = 717), and a reference cohort without either diagnosis (n = 548,532). Main outcomes were rehospitalization for condition(s) other than mental illness: (1) through the ED; (2) any admission, and (3) admission resulting in death. Cox regression was used to analyze time to main outcomes controlling for prespecified covariates associated with rehospitalization.

RESULTS

The risk of rehospitalization via the ED was increased for people with CKD (hazard ratio, HR = 1.24, 95% confidence interval, CI = 1.21-1.28, p < 0.001) and co-occurring SMI (HR = 1.33, 95% CI = 1.29-1.38, p < 0.001) cohorts, but was significantly greater in the combined cohort (HR = 1.55, 95% CI = 1.40-1.73, p < 0.001). Similarly, the risk of any rehospitalization was increased for CKD (HR = 1.21, 95% CI = 1.17-1.25, p < 0.001) and co-occurring SMI (HR = 1.14, 95% CI = 1.11-1.17, p < 0.001) cohorts, while a significantly greater risk was observed for the combined cohort (HR = 1.36, 95% CI = 1.24-1.48, p < 0.001). The risk of rehospitalization resulting in death was not significantly increased in the combined cohort.

CONCLUSION

In people with CKD, co-occurring SMI increased the risk of experiencing rehospitalization, particularly through the ED. Studies of strategies to address SMI in the CKD population are needed to mitigate the risk of repeat hospital admissions.

The effect of serious mental illness on the risk of rehospitalization among patients with diabetes

BACKGROUND

Medical-surgical rehospitalizations within a month after discharge among patients with diabetes result in tremendous costs to the US health care system.

OBJECTIVE

The study's aim was to examine whether co-morbid serious mental illness diagnoses (bipolar disorder, schizophrenia, or other psychotic disorders) among patients with diabetes are independently associated with medical-surgical rehospitalization within a month of discharge after an initial hospitalization.

METHODS

This cohort study of all community hospitals in Washington state evaluated data from 82,060 adults discharged in the state of Washington with any International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis indicating diabetes mellitus between 2010 and 2011. Data on medical-surgical hospitalizations were obtained from the Washington State Comprehensive Hospital Abstract Reporting System. Co-morbid serious mental illness diagnoses were identified based on International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes indicating bipolar disorder, schizophrenia, or other psychotic disorders. Logistic regression analyses identified factors independently associated with rehospitalization within a month of discharge. Cox proportional hazard analyses estimated time to rehospitalization for the entire study period.

RESULTS

After adjusting for demographics, medical co-morbidity, and characteristics of the index hospitalization, co-morbid serious mental illness diagnosis was independently associated with increased odds of rehospitalization within 1 month among patients with diabetes who had a medical-surgical hospitalization (odds ratio: 1.24, 95% confidence interval: 1.07, 1.44). This increased risk of rehospitalization persisted throughout the study period (up to 24 mo).

CONCLUSIONS

Co-morbid serious mental illness in patients with diabetes is independently associated with greater risk of early medical-surgical rehospitalization. Future research is needed to define and specify targets for interventions at points of care transition for this vulnerable patient population.

Psychometric properties of the adjective rating scale for withdrawal across treatment groups, gender, and over time

The adjective rating scale for withdrawal (ARSW) is commonly used to assess opiate withdrawal in clinical practice and research. The aims of this study were to examine the factor structure of the ARSW, test measurement invariance across gender and treatment groups, and assess longitudinal measurement invariance across the clinical trial. Secondary data analysis of the National Drug Abuse Treatment Clinical Trials Network 000-3, a randomized clinical trial comparing two tapering strategies, was performed. The ARSW was analyzed at baseline, end of taper and 1-month follow-up (N=515 opioid-dependent individuals). A 1-factor model of the ARSW fit the data and demonstrated acceptable reliability. Measurement invariance was supported across gender and taper groups. Longitudinal measurement invariance was not found across the course of the trial, with baseline assessment contributing to the lack of invariance. If change over time is of interest, change from post-treatment through follow-up may offer the most valid comparison.

Preliminary findings: Contingency management targeting psycho-stimulant use results in secondary decreases in smoking for severely mentally ill adults

BACKGROUND

Treatments for drug addiction and smoking in severely mentally ill (SMI) adults are needed.

OBJECTIVES

To investigate the effect of a contingency management (CM) intervention targeting psycho-stimulant on cigarette smoking.

METHODS

126 stimulant dependent SMI smokers were assigned to CM or a non-contingent control condition. Rates of smoking-negative (<3 ppm) carbon monoxide breath-samples were compared.

RESULTS

Individuals who received CM targeting psycho-stimulants were 79% more likely to submit a smoking-negative breath-sample relative to controls.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

This study provides initial evidence that a behavioral treatment for drug use results in reductions in cigarette smoking in SMI adults.

Longitudinal missing data strategies for substance use clinical trials using generalized estimating equations: an example with a buprenorphine trial

OBJECTIVE

A review of substance use clinical trials indicates that sub-optimal methods are the most commonly used procedures to deal with longitudinal missing information.

METHODS

Listwise deletion (i.e., using complete cases only), positive urine analysis (UA) imputation, and multiple imputation (MI) were used to evaluate the effect of baseline substance use and buprenorphine/naloxone tapering schedule (7 or 28 days) on the probability of a positive UA (UA+) across the 4-week treatment period.

RESULTS

The listwise deletion generalized estimating equations (GEE) model demonstrated that those in the 28-day taper group were less likely to submit a UA+ for opioids during the treatment period (odds ratios (OR) = 0.57, 95% confidence interval (CI): 0.39-0.83), as did the positive UA imputation model (OR = 0.43, CI: 0.34-0.55). The MI model also demonstrated a similar effect of taper group (OR = 0.57, CI: 0.42-0.77), but the effect size was more similar to that of the listwise deletion model.

CONCLUSIONS

Future researchers may find utilization of the MI procedure in conjunction with the common method of GEE analysis as a helpful analytic approach when the missing at random assumption is justifiable.

Predictors of stimulant abuse treatment outcomes in severely mentally ill outpatients

BACKGROUND

Severe mental illness is often exclusionary criteria for studies examining factors that influence addiction treatment outcome. Therefore, little is known about predictors of treatment response of individuals receiving psychosocial treatments for addictions who suffer from co-occurring severe mental illness.

METHODS

The impact of demographic, substance abuse severity, psychiatric severity, and service utilization variables on in-treatment performance (i.e., longest duration of abstinence) in a 12-week contingency management (CM) intervention for stimulant abuse in 96 severely mentally ill adults was investigated. A 4-step linear regression was used to identify independent predictors of in-treatment abstinence.

RESULTS

This model accounted for 37.4% of variance in the longest duration of abstinence outcome. Lower levels of stimulant use (i.e., stimulant-negative urine test) and psychiatric severity (i.e., lower levels of psychiatric distress), as well as higher rates of outpatient treatment utilization at study entry were independently associated with longer duration of drug abstinence.

CONCLUSION

These data suggest that individuals with low levels of stimulant use and psychiatric severity, as well as those actively engaged in services are most likely to succeed in a typical CM intervention. For others, modifications to CM interventions, such as increasing the value of reinforcement or adding CM to evidence based psychiatric interventions may improve treatment outcomes.

Depression and pain interference among patients with chronic pain after ED encounters

INTRODUCTION

Patients with chronic pain who frequent emergency departments present a challenge to health care providers. Mental health, substance abuse, and pain issues are difficult to distinguish in fast-paced clinical settings, and significant symptoms may remain unaddressed. This pilot study sought to determine whether electronically delivered screening tools measuring pain and mood could identify areas to target for improving emergency care.

METHODS

A prospective, descriptive pilot study used repeated measures of validated instruments to investigate the status of patients after their ED encounter. Persons with chronic pain not related to cancer and documented opioid use were recruited by nursing personnel after an ED encounter. Consenting participants (n = 52) were invited to perform an online survey that included self-reported measurements of pain intensity, pain interference, depression, subjective health, and health distress. The survey was repeated after 8 weeks.

RESULTS

The baseline survey was completed by 42.3% of 52 patients who provided consent (n = 22, 68.2% female). The mean pain severity score was 5.96 (SD 1.57) and the mean pain interference score was 7.52 (SD 1.81) using 0 to 10 scales of the Brief Pain Inventory. Personal Health Questionnaire Depression Scale ratings indicated that a major depressive disorder should be considered for 54% of the participants.

DISCUSSION

Online surveys delivered to patients with chronic pain detected unmet needs for depression and persisting high levels of pain interference after ED encounters. Adding mood-specific screening tools to pain assessments may be necessary in clinical settings to identify depression and refer for appropriate treatment.

Criminal justice referral and incentives in outpatient substance abuse treatment

A substantial number of substance abusers entering outpatient psychosocial counseling treatment are referred from the criminal justice (CJ) system. This secondary analysis of previously published findings from a large (N=415) multi-site trial of a prize-based abstinence incentive intervention (Petry et al., 2005) examined the influence of CJ referral on usual care outcomes and response to the incentive procedure. CJ referrals (n=138) were more likely than those not CJ referred (n=277) to provide stimulant negative urine samples whether missing samples were counted as positive (50 versus 41%, p=.016) or as missing (96 versus 91%, p<.001). A significant interaction term was found only for percentage of treatment completers (p=.027). However, on that retention variable, and three additional drug use measures, significant incentive effects were confined to participants who entered treatment without referral from the criminal justice system. The study suggests that abstinence incentives should be offered as a first priority to stimulant users entering treatment without criminal justice referral. However, incentives can be considered for use with CJ-referred stimulant users based on the observation that best outcomes were obtained in CJ referrals who also received the abstinence incentive program.

Who prescribes buprenorphine for rural patients? The impact of specialty, location and practice type in Washington State

We determined the specialty, geographic location, practice type and treatment capacity of waivered clinicians in Washington State. We utilized the April 2011 Drug Enforcement Agency roster of all waivered buprenorphine prescribers and cross-referenced the data with information from the American Medical Association and online resources. Waivered physicians, as compared to Washington State physicians overall, are more likely to be primary care providers, be older, less likely to be younger than 35 years, and more likely to be female. Isolated rural areas have the lowest provider to population ratios. Ten counties lack either a buprenorphine provider or a methadone clinic. In rural areas, waivered physicians work predominately in federally-subsidized safety-net settings, which underscores the need for continued governmental support of primary care and mental health in these settings.

Missing data in substance abuse treatment research: current methods and modern approaches

Two common procedures for the treatment of missing information, listwise deletion and positive urine analysis (UA) imputation (e.g., if the participant fails to provide urine for analysis, then score the UA positive), may result in significant biases during the interpretation of treatment effects. To compare these approaches and to offer a possible alternative, these two procedures were compared to the multiple imputation (MI) procedure with publicly available data from a recent clinical trial. Listwise deletion, single imputation (i.e., positive UA imputation), and MI missing data procedures were used to comparatively examine the effect of two different buprenorphine/naloxone tapering schedules (7- or 28-days) for opioid addiction on the likelihood of a positive UA (Clinical Trial Network 0003; Ling et al., 2009). The listwise deletion of missing data resulted in a nonsignificant effect for the taper while the positive UA imputation procedure resulted in a significant effect, replicating the original findings by Ling et al. (2009). Although the MI procedure also resulted in a significant effect, the effect size was meaningfully smaller and the standard errors meaningfully larger when compared to the positive UA procedure. This study demonstrates that the researcher can obtain markedly different results depending on how the missing data are handled. Missing data theory suggests that listwise deletion and single imputation procedures should not be used to account for missing information, and that MI has advantages with respect to internal and external validity when the assumption of missing at random can be reasonably supported.

Hookah use: going down in smoke

This article provides a review of tobacco smoking using a hookah, an emerging threat to public health, especially among young adults. Knowledge deficits persist in regards to this form of smoking, because many perceive it as less harmful than cigarette smoking and little research is available. Knowledge about hookah smoking can be instrumental in guiding health professionals to address this practice with their clients and in their communities. A failure to address all tobacco products as unique, individual entities undermines any success in public policy efforts to control tobacco use.
