Psychiatric comorbidity and order of condition onset among patients seeking treatment for chronic pain and opioid use disorder.

BACKGROUND: The study objective was to compare psychiatric comorbidity among patients seeking treatment for chronic pain and opioid use disorder (OUD) by order of condition onset (i.e., "Pain First," "OUD First," "Same Time"). METHODS: Data from 170 patients entering two clinical trials of treatments for current comorbid chronic pain and OUD conducted between March 2009 and July 2013 were compared by order of condition onset. The Structured Clinical Interview for DSM-IV-TR Axis I Disorders and the Diagnostic Interview for DSM-IV Personality Disorders (Axis II) were performed by doctoral-level providers using a standardized training protocol. Age of onset group differences on specific diagnostic variables were examined using multinomial logistic regression. RESULTS: Fifty-two percent were in the "Pain First" group (n = 89), 35 % in the "OUD First" group (n = 59), and 13 % in the "Same Time" group (n = 22). Compared with the Pain First group, the Same Time group was less likely to report heroin (vs. prescription opioids) as the primary drug used (OR = 0.20, 95 % CI = 0.06-0.72) or meet criteria for an Axis II disorder (OR = 0.24, 95 % CI = 0.07-0.83). Compared with the Pain First group, the OUD First group was more likely to meet criteria for a current nonopioid substance use disorder (OR = 3.20, 95 % CI = 1.22-8.40). CONCLUSIONS: Our findings regarding differences in psychiatric comorbidity associated with order of condition onset indicate that varying pathways may exist for the emergence of chronic pain and OUD; further research should investigate potential treatment implications.

Behavioral counseling and abstinence-contingent take-home buprenorphine in general practitioners' offices in Malaysia: a randomized, open-label clinical trial.

BACKGROUND AND AIM: To address the widespread severe problems with opioid use disorder, buprenorphine-naloxone treatment provided by primary care physicians has greatly expanded treatment access; however, treatment is often provided with minimal or no behavioral interventions. Whether or which behavioral interventions are feasible to implement in various settings and improve treatment outcomes has not been established. This study aimed to evaluate two behavioral interventions to improve buprenorphine-naloxone treatment. DESIGN: A 2 × 2 factorial, repeated-measures, open-label, randomized clinical trial. SETTINGS: General medical practice offices in Muar, Malaysia. PARTICIPANTS: Opioid-dependent individuals (n = 234). INTERVENTIONS: Participants were randomly assigned to one of four treatment conditions and received study interventions for 24 weeks: (1) physician management with or without behavioral counseling and (2) physician management with or without abstinence-contingent buprenorphine-naloxone (ACB) take-home doses. MEASUREMENTS: The primary outcomes were proportions of opioid-negative urine tests and HIV risk behaviors [assessed by audio computer-assisted AIDS risk inventory (ACASI-ARI)]. FINDINGS: The rates of opioid-negative urine tests over 24 weeks of treatment were significantly higher with [68.2%, 95% confidence interval (CI) = 65-71] than without behavioral counseling (59.2%, 95% CI = 56-62, P < 0.001) and with (71.0%, 95% CI = 68-74) than without ACB (56.4%, 95% CI = 53-59, P < 0.001); interaction effects between and among behavioral interventions and time were not statistically significant. Scores on ACASI-ARI decreased significantly from baseline across all treatment groups (P < 0.001) and did not differ significantly with or without behavioral counseling (P = 0.099) or with or without ACB (P = 0.339). CONCLUSIONS: Providing opioid-dependent patients in Muar, Malaysia with buprenorphine-naloxone and physician management plus behavioral counseling or abstinence-contingent buprenorphine-naloxone (ACB) resulted in greater reductions of opioid use compared with providing buprenorphine-naloxone and physician management without behavioral counseling or ACB.

Impact of 12 step mutual help groups on drug use disorder patients across six clinical trials.

BACKGROUND: 12 step mutual help groups are widely accessed by people with drug use disorder but infrequently subjected to rigorous evaluation. Pooling randomized trials containing a condition in which mutual help group attendance is actively facilitated presents an opportunity to assess the effectiveness of 12 step groups in large, diverse samples of drug use disorder patients. METHODS: Data from six federally-funded randomized trials were pooled (n = 1730) and subjected to two-stage instrumental variables modelling, and, fixed and random effects regression models. All trials included a 12 step group facilitation condition and employed the Addiction Severity Index as a core measure. RESULTS: The ability of 12 step facilitation to increase mutual help group participation among drug use disorder patients was minimal, limiting ability to employ two-stage instrumental variable models that correct for selection bias. However, traditional fixed and random effect regression models found that greater 12 step mutual help group attendance by drug use disorder patients predicted reduced use of and problems with illicit drugs and also with alcohol. CONCLUSION: Facilitating significant and lasting involvement in 12 step groups may be more challenging for drug use disorder patients than for alcohol use disorder patients, which has important implications for clinical work and for effectiveness evaluations. Though selection bias could explain part of the results of traditional regression models, the finding that participation in 12 step mutual help groups predicts lower illicit drug and alcohol use and problems in a large, diverse, sample of drug use disorder patients is encouraging.

An evaluation of the feasibility, acceptability, and preliminary efficacy of cognitive-behavioral therapy for opioid use disorder and chronic pain.

AIMS: The primary study aim was to evaluate the feasibility and acceptability of cognitive-behavioral therapy (CBT) for opioid use disorder and chronic pain. The secondary aim was to examine its preliminary efficacy. METHODS: In a 12-week pilot randomized clinical trial, 40 methadone-maintained patients were assigned to receive weekly manualized CBT (n = 21) or Methadone Drug Counseling (MDC) to approximate usual drug counseling (n = 19). RESULTS: Twenty of 21 patients assigned to CBT and 18 of 19 assigned to MDC completed the pilot study. Mean (SD) sessions attended were 8.4 (2.9) for CBT (out of 12 possible) and 3.8 (1.1) for MDC (out of 4 possible); mean (SD) patient satisfaction ratings (scored on 1-7 Likert-type scales) were 6.6 (0.5) for CBT and 6.0 (0.4) for MDC (p < .001). The proportion of patients abstinent during the baseline and each successive 4-week interval was higher for patients assigned to CBT than for those assigned to MDC [Wald χ2 (1) = 5.47, p = .02]; time effects (p = .69) and interaction effects between treatment condition and time (p = .10) were not significant. Rates of clinically significant change from baseline to end of treatment on pain interference (42.9% vs. 42.1%, [χ2 (1, N = 40) = 0.002, p = 0.96]) did not differ significantly for patients assigned to CBT or MDC. CONCLUSIONS: We found support for the feasibility, acceptability, and preliminary efficacy of cognitive-behavioral therapy relative to standard drug counseling in promoting abstinence from nonmedical opioid use among patients with opioid use disorder and chronic pain. Overall, patients exhibited improved pain outcomes, but these improvements did not differ significantly by treatment condition.

Ketamine interactions with gut-microbiota in rats: relevance to its antidepressant and anti-inflammatory properties.

BACKGROUND: Appreciable evidence suggest that dysbiosis in microbiota, reflected in gut microbial imbalance plays a key role in the pathogenesis of neuropsychiatric disorders including depression and inflammatory diseases. Recently, the antidepressant properties of ketamine have gained prominence due to its fast and long lasting effects. Additional uses for ketamine in inflammatory disorders such as irritable bowel syndrome have been suggested. However, ketamine's exact mechanism of action and potential effects on microbiome is not known. Here, we examined the effects of low dose ketamine, known to induce antidepressant effects, on stool microbiome profile in adult male Wistar rats. Animals (5/group) were injected intraperitoneally with ketamine (2.5 mg/kg) or saline, daily for 7 days and sacrificed on day 8 when intestinal stools were collected and stored at - 80 °C. DNA was extracted from the samples and the 16 S rRNA gene-based microbiota analysis was performed using 16S Metagenomics application. RESULTS: At genus-level, ketamine strikingly amplified Lactobacillus, Turicibacter and Sarcina by 3.3, 26 and 42 fold, respectively. Conversely, opportunistic pathogens Mucispirillum and Ruminococcus were reduced by approximately 2.6 and 26 fold, respectively, in ketamine group. Low levels of Lactobacillus and Turicibacter are associated with various disorders including depression and administration of certain species of Lactobacillus ameliorates depressive-like behavior in animal models. Hence, some of the antidepressant effects of ketamine might be mediated through its interaction with these gut bacteria. Additionally, high level of Ruminococcus is positively associated with the severity of irritable bowel syndrome (IBS), and some species of Mucispirillum have been associated with intestinal inflammation. Indirect evidence of anti-inflammatory role of Sarcina has been documented. Hence, some of the anti-inflammatory effects of ketamine and its usefulness in specific inflammatory diseases including IBS may be mediated through its interaction with these latter bacteria. CONCLUSION: Our data suggest that at least some of the antidepressant and anti-inflammatory effects of daily ketamine treatment for 7 days may be mediated via its interaction with specific gut bacteria. These findings further validate the usefulness of microbiome as a target for therapeutic intervention and call for more detailed investigation of microbiome interaction with central mediators of mood and/or inflammatory disorders.

Psychotherapy with American Indians: An exploration of therapist-rated techniques in three urban clinics.

The aim of the project was to conduct psychotherapy research in American Indian mental health clinics. To date, very little psychotherapy research has been conducted in this area. We report the findings from a multisite investigation of psychotherapy techniques used with American Indians. Psychotherapists, working in three American Indian clinics, were asked to self-report the therapeutic interventions that they used in sessions with 93 separate adult American Indian outpatients. Each therapist rated each client exactly once, and thus data on 93 sessions were collected. Therapists' self-reported technique use with the Multitheoretical List of Therapist Interventions (McCarthy & Barber, 2009). Ratings were made immediately following the delivery of a session. The common factors approach was the most reported approach, followed by person-centered and interpersonal approaches. However, the therapists reported using techniques from all of the main therapeutic approaches. Technique use was affected by client- (demographic and diagnostic), therapist-, and therapy-related variables. This project represents a promising start to systematic psychotherapy research in busy, urban American Indian clinics. Many psychotherapeutic techniques are utilized, and there are many avenues for future research. A replication with client and observer ratings will be an important next step.

Atomoxetine for amphetamine-type stimulant dependence during buprenorphine treatment: A randomized controlled trial.

BACKGROUND: Amphetamine type stimulants (ATS) use is highly prevalent and frequently co-occurs with opioid dependence in Malaysia and Asian countries. No medications have established efficacy for treating ATS use disorder. This study evaluated the safety, tolerability, and potential efficacy of atomoxetine for treating ATS use disorder. METHODS: Participants with opioid and ATS dependence (N = 69) were enrolled in a pilot, double-blind, placebo-controlled randomized clinical trial; all received buprenorphine/naloxone and behavioral counseling and were randomized to atomoxetine 80 mg daily (n = 33) or placebo (n = 33). The effect size of the between-group difference on the primary outcome, proportion of ATS-negative urine tests, was estimated using Cohen's d for the intention-to-treat (ITT) sample and for higher adherence subsample (≥60 days of atomoxetine or placebo ingestion). RESULTS: Participants were all male with mean (SD) age 39.4 (6.8) years. The proportion of ATS-negative urine tests was higher in atomoxetine- compared to placebo-treated participants: 0.77 (0.63-0.91) vs. 0.67 (0.53-0.81, d = 0.26) in the ITT sample and 0.90 (0.75-1.00) vs. 0.64 (0.51-0.78, d = 0.56) in the higher adherence subsample. The proportion of days abstinent from ATS increased from baseline in both groups (p < 0.001) and did not differ significantly between atomoxetine- and placebo-treated participants (p = 0.42). Depressive symptoms were reduced from baseline in both groups (p < 0.02) with a greater reduction for atomoxetine- than placebo-treated participants (p < 0.02). There were no serious adverse events or adverse events leading to medication discontinuation. CONCLUSIONS: The findings support clinical tolerability and safety and suggest potential efficacy of atomoxetine for treating ATS use disorder in this population.

An investigation of an open-access model for scaling up methadone maintenance treatment.

AIMS: To examine retrospectively patient and programmatic outcomes following the development and implementation of an 'open-access' model in which prospective patients were enrolled rapidly in methadone maintenance treatment, irrespective of ability to pay, and provided real-time access to multiple voluntary treatment options. DESIGN: Medical and administrative records were abstracted to compare data for 1 year before and 9 years after initiating the implementation of an open-access treatment model in May 2007. SETTING: Methadone maintenance treatment center in Connecticut, USA. PARTICIPANTS: Individuals with opioid use disorder entering treatment between July 2006 and June 2015. In June 2015, 64% (n = 2594) of the sample were men and 80% (n = 3133) reported that they were white. INTERVENTION: The Network for the Improvement of Addiction Treatment-informed open-access treatment model uses process improvement strategies to improve treatment access and capacity. MEASUREMENTS: Census, waiting time, retention, non-medical opioid use, patient mortality and financial sustainability (net income and state-block grants as proportions of revenue). FINDINGS: In the 9 years following the initial implementation of the open-access model, patient census increased by 183% from 1431 to 4051, and average waiting-time days decreased from 21 to 0.3 (same day) without apparent deleterious effects on rates of retention, non-medical opioid use or mortality. Between fiscal years (FY) 06 and FY 15, net operating margin rose from 2 to 10%, while state-block grant revenues declined 14% and the proportion of total revenue from state-block grant revenue decreased from 49 to 24%. CONCLUSIONS: An open-access model for rapid enrolment of people with opioid use disorder in methadone treatment appears to improve treatment access, capacity, and financial sustainability without evidence of deleterious effects on treatment outcomes.

Customized recommendations and reminder text messages for automated, computer-based treatment during methadone.

The Recovery Line is an automated, computer-based intervention based on cognitive behavioral therapy (CBT) designed to provide real-time assistance by phone for patients in methadone maintenance. Preliminary efficacy findings were promising, however, as with other computer-based systems for substance use disorder, patient system use was less than recommended. Development and evaluation of system functions to increase patient engagement and use is needed. Thus, we conducted two randomized trials to evaluate system functions designed to increase patient use of the Recovery Line among methadone-maintained patients with continued illicit drug use. In Trial 1 (n = 60), patients received customized, system use recommendations or no recommendations on each Recovery Line call. Ratings of system usability were higher for customized recommendations (CR), but number of calls and total call time did not differ by condition. Trial 2 evaluated characteristics of reminder messages (message frame and reminder latency). Participants (N = 67) received gain- and loss-frame reminder messages, and were randomly assigned to immediate, short, or long term message latency. Although message framing had no effect, gender interacted with latency condition such that females did not differ by message latency, while males had significantly greater total contact time in the short latency conditions. Number of calls differed by condition over time such that the shorter latencies led to greater calls initially, but dissipated over time. Overall the study indicates that computer-based self-management systems can be adapted to increase patient engagement and use. (PsycINFO Database Record

Early Initiation of Amphetamine-Type Stimulants (ATS) Use Associated with Lowered Cognitive Performance among Individuals with Co-Occurring Opioid and ATS Use Disorders in Malaysia.

Amphetamine-type stimulants (ATS) use is increasingly prevalent in Malaysia, including among individuals who also use opioids. We evaluated cognitive functioning profiles among individuals with co-occurring opioid and ATS dependence and their lifetime patterns of drug use. Participants (N = 50) enrolling in a clinical trial of buprenorphine/naloxone treatment with or without atomoxetine completed the Raven's Standard Progressive Matrices, Rey-Osterrieth Complex Figure Test, Digit Span, Trail Making and Symbol Digit Substitution tasks. Multidimensional scaling and a K-means cluster analyses were conducted to classify participants into lower versus higher cognitive performance groups. Subsequently, analyses of variance procedures were conducted to evaluate between group differences on drug use history and demographics. Two clusters of individuals with distinct profiles of cognitive performance were identified. The age of ATS use initiation, controlling for the overall duration of drug use, was significantly earlier in the lower than in the higher cognitive performance cluster: 20.9 (95% CI: 18.0-23.8) versus 25.2 (95% CI: 22.4-28.0, p = 0.038). While adverse effects of ATS use on cognitive functioning can be particularly pronounced with younger age, potentially related to greater vulnerability of the developing brain to stimulant and/or neurotoxic effects of these drugs, the current study findings cannot preclude lowered cognitive performance before initiation of ATS use.

Cognitive Behavioral Therapy Improves Treatment Outcomes for Prescription Opioid Users in Primary Care Buprenorphine Treatment.

To determine whether treatment outcomes differed for prescription opioid and heroin use disorder patients, we conducted a secondary analysis of a 24-week (N=140) randomized trial of physician management (PM) or PM plus cognitive behavioral therapy (CBT) in primary care buprenorphine/naloxone treatment. Self-reported opioid use and urine toxicology analyses were obtained weekly. We examined baseline demographic differences between primary prescription opioid use patients (n=49) and primary heroin use patients (n=91) and evaluated whether treatment response differed by assigned condition. Compared to primary heroin use patients, primary prescription opioid use patients had marginally fewer years of opioid use, were less likely to have had a previous drug treatment or detoxification, and were less likely to report injection drug use. Although opioid abstinence only, and treatment retention did not differ by opioid use group, opioid category moderated the effect of CBT on urine samples negative for all drugs. Primary prescription opioid use patients assigned to PM-CBT had more than twice the mean number of weeks of abstinence for all drugs (7.6) than those assigned to PM only (3.6; p=.02), while primary heroin use patients did not differ by treatment. Findings suggest that examination of other factors that may predict response to behavioral interventions is warranted.

Psychiatric Disorders Among Patients Seeking Treatment for Co-Occurring Chronic Pain and Opioid Use Disorder.

OBJECTIVE: Psychiatric comorbidities complicate treatment of patients with chronic pain and opioid use disorder, but the prevalence of specific comorbid psychiatric disorders in this population has not been systematically investigated. METHODS: 170 consecutive participants entering a treatment research program for co-occurring chronic pain and opioid use disorder between March 2009 and July 2013 were evaluated with the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID-I/P) and the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). RESULTS: The prevalence of any lifetime (and current) comorbid Axis I disorder was 91% (75%); 52% met criteria for lifetime anxiety disorder (48% current), 57% for lifetime mood disorder (48% current), and 78% for lifetime nonopioid substance use disorder (34% current). Common current anxiety diagnoses were posttraumatic stress disorder (21%), generalized anxiety disorder (16%), and panic disorder without agoraphobia (16%). Common current mood diagnoses were major depressive disorder (40%) and dysthymia (11%). A majority of patients had a personality disorder (52%). CONCLUSIONS: High rates and persistence of co-occurring psychiatric disorders, including anxiety or mood disorders, may explain in part the difficulty providers have treating patients with co-occurring opioid use disorder and chronic pain and suggest possible targets for improving treatment. TRIAL REGISTRATION: ClinicalTrials.gov identifiers: buprenorphine/naloxone treatment (NCT00634803), opioid treatment program-based methadone maintenance treatment (NCT00727675).

Emerging Drug Use Trends in Kelantan, Malaysia.

The primarily rural and agrarian Kelantan province of Malaysia has high rates of drug use and is characterized by unique sociocultural factors. Combining qualitative and ethnographic methods, we investigated drug use and treatment needs of people who use drugs (PWUD) in rural areas of Kelantan. In February 2014, field visits, participant observation, and focus group discussions (FGDs) with 27 active PWUD were conducted in rural areas surrounding the capital city of Kelantan. The findings indicate a high prevalence of opiate and amphetamine type stimulants (ATS) use in these areas. FGD participants reported initiating drug use at early ages due to peer influences, to relieve boredom, to cope with problems, and a high saturation of villages with other PWUD was reported as a major contributor to their own continued drug use. They reported a trend of drug use initiation at younger ages and increased drug use among females. Participants were interested in treatment; however, their limited knowledge about treatment options and perceived limited availability of services were barriers to treatment seeking. Easy access to drugs, primarily from Thailand and facilitated by the use of mobile phones, resulted in an expanding prevalence of drug use that underscores the need to bolster education and prevention efforts and accessibility of treatment services in Kelantan.

Physical activity, psychiatric distress, and interest in exercise group participation among individuals seeking methadone maintenance treatment with and without chronic pain.

BACKGROUND AND OBJECTIVES: Physical activity may improve chronic pain, anxiety, and depression, which are prevalent among patients in methadone maintenance treatment (MMT), but relatively little is known about the physical activity levels or interest in exercise of patients in MMT. METHODS: We used a brief self-report instrument to assess physical activity levels, chronic pain, psychiatric distress, and interest in exercise group participation among 303 adults seeking MMT. RESULTS: Most (73%) reported no moderate or vigorous intensity physical activity in the past week; 27% met recommended physical activity levels, and 24% reported interest in exercise group participation. Participants with (compared to those without) chronic pain had higher levels of psychiatric distress and were less likely to meet recommended levels of physical activity (p < .05), but did not differ significantly in their interest in participating in an exercise group. Participants who met recommended levels of physical activity in the past week were more likely to be men and had lower levels of depression than others (p < .05). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Low levels of physical activity and low interest in exercise group participation among patients entering MMT point to the need for and likely challenges of implementing exercise interventions in MMT.

Aripiprazole and Risperidone for Treatment of Methamphetamine-Associated Psychosis in Chinese Patients.

We evaluated tolerability and efficacy of aripiprazole and risperidone for treatment of methamphetamine (METH) associated psychotic symptoms in China. Patients with acute METH-associated psychotic symptoms (N=42) and with Positive and Negative Syndrome Scale (PANSS) total score between 60 and 120 were randomized to aripiprazole (initial dose 5-10mg per day followed by flexible doses 5-15 mg per day) or risperidone (initial dose 2-4 mg per day followed by flexible doses 4-6 mg per day) from day 3 to 25 of inpatient hospital stay. Outcome measures included PANSS and Clinical Global Impressions-Severity of Illness scale (CGI-S), METH craving Visual Analogue Scale (VAS), Simpson Angus Scale (SAS), Barnes Assessments Akathasia Rating Scale (BARS), and self-reported adverse effects evaluated during treatment. Retention was evaluated using Kaplan-Meier survival analysis and the MIXED models procedure was used to compare the groups on measures of psychotic and extra-pyramidal symptoms. Patients in both aripiprazole and risperidone groups showed statistically significant reductions in psychotic symptomatology from baseline during treatment (p<0.001) with no statistically significant differences between the treatment groups (p=0.73 and p=0.15, respectively). Risperidone-treated patients reported significantly greater METH craving reductions (p<0.001). Overall, 71% of patients completed the entire study, but the aripiprazole group had a significantly lower retention than the risperidone group (p=0.007), primarily due to medication related adverse effects. Aripiprazole-treated patients also had significantly more akathisia (p=0.03) and agitation (p=0.02) than risperidone-treated patients. Patients in both groups who tolerated their medications and completed the entire study achieved comparable reductions of psychotic symptoms.

Medical treatments for opioid use disorder in Iran: a randomized, double-blind placebo-controlled comparison of buprenorphine/naloxone and naltrexone maintenance treatment.

AIMS: With the broad goals of developing a clinical research and training program and disseminating effective opioid use disorder treatments in Iran, this pilot clinical trial compared the effectiveness of oral naltrexone (NTX) and sublingual buprenorphine/naloxone (BNX). DESIGN: Twelve-week single-site, two-group parallel randomized double-blind clinical trial. SETTING: An out-patient clinical research program in Tehran, Iran. PARTICIPANTS: Following medically assisted withdrawal, participants with opioid use disorder were assigned randomly to NTX (n = 51) or BNX (n = 51). INTERVENTION: Medications were administered three times per week, double-blind, double-dummy for 12 weeks. All participants received weekly group drug counseling. MEASUREMENTS: The primary outcome was initial duration of opioid abstinence verified by urine toxicology tests. Secondary outcomes included the number of opioid-negative urine tests, treatment retention and proportions with sustained, verified opioid-abstinence for 12 weeks. FINDINGS: Mean [95% confidence interval (CI)] number of days of initial duration of verified abstinence was 28.8 (20.0-37.5) with BNX and 21.6 (14.4-28.7) with NTX (P = 0.205). The mean (95% CI) number of opioid-negative urine tests was 19.7 (17.7-21.6) with BNX and 15.4 (13.1-17.8) with NTX (P = 0.049). The mean (95% CI) number of days in treatment was 70.6 (63.6-77.7) with BNX versus 56.5 (47.8-65.3) with NTX (P = 0.013). The rate of sustained, 12-week opioid abstinence was 16% (8/51) in the BNX group and 8% (4/51) in the NTX group (P = 0.219). CONCLUSIONS: Among patients with opioid use disorder in Iran, sublingual buprenorphine/naloxone was associated with a greater number of opioid-negative urine tests and treatment retention than oral naltrexone, but not significantly greater initial abstinence duration or proportions with sustained abstinence.

Drug Counselors' Attitudes Toward Nonpharmacologic Treatments for Chronic Pain.

OBJECTIVES: To examine methadone counselors' attitudes toward individual and group-based nonpharmacologic treatments for chronic pain. METHODS: Thirty methadone drug counselors were interviewed about their attitudes toward pain interventions and completed a survey on the perceived efficacy of and willingness to refer patients to nonpharmacologic pain treatments. RESULTS: Counselors reported favorable attitudes toward interventions commonly found in interdisciplinary pain management, particularly, conventional psychological approaches. On average, counselors rated cognitive-behavioral therapy (individual or group) as the treatment with the highest perceived efficacy and the one to which they were most willing to refer patients with pain. In contrast, on average, counselors rated the use of herbal medicine, aromatherapy, and magnets among the lowest in perceived efficacy and in willingness to refer patients with pain. Generally, higher perceived efficacy was associated with higher referral willingness, and scores on both dimensions were comparable across individual and group interventions. CONCLUSIONS: Findings indicate that methadone drug counselors perceive several nonpharmacologic evidence-based pain treatments as efficacious for methadone-maintained patients with chronic pain and counselors would be willing to refer their patients to these therapies if they were available. If some of these nonpharmacologic interventions were shown to be effective in methadone maintenance treatment, they have the potential to address, at least in part, the routine undertreatment of pain in this vulnerable patient population.

Primary care-based buprenorphine taper vs maintenance therapy for prescription opioid dependence: a randomized clinical trial.

IMPORTANCE: Prescription opioid dependence is increasing and creates a significant public health burden, but primary care physicians lack evidence-based guidelines to decide between tapering doses followed by discontinuation of buprenorphine hydrochloride and naloxone hydrochloride therapy (hereinafter referred to as buprenorphine therapy) or ongoing maintenance therapy. OBJECTIVE: To determine the efficacy of buprenorphine taper vs ongoing maintenance therapy in primary care-based treatment for prescription opioid dependence. DESIGN, SETTING, AND PARTICIPANTS: We conducted a 14-week randomized clinical trial that enrolled 113 patients with prescription opioid dependence from February 17, 2009, through February 1, 2013, in a single primary care site. INTERVENTIONS: Patients were randomized to buprenorphine taper (taper condition) or ongoing buprenorphine maintenance therapy (maintenance condition). The buprenorphine taper was initiated after 6 weeks of stabilization, lasted for 3 weeks, and included medications for opioid withdrawal, after which patients were offered naltrexone treatment. The maintenance group received ongoing buprenorphine therapy. All patients received physician and nurse support and drug counseling. MAIN OUTCOMES AND MEASURES: Illicit opioid use via results of urinanalysis and patient report, treatment retention, and reinitiation of buprenorphine therapy (taper group only). RESULTS: During the trial, the mean percentage of urine samples negative for opioids was lower for patients in the taper group (35.2% [95% CI, 26.2%-44.2%]) compared with those in the maintenance group (53.2% [95% CI, 44.3%-62.0%]). Patients in the taper group reported more days per week of illicit opioid use than those in the maintenance group once they were no longer receiving buprenorphine (mean use, 1.27 [95% CI, 0.60-1.94] vs 0.47 [95% CI, 0.19-0.74] days). Patients in the taper group had fewer maximum consecutive weeks of opioid abstinence compared with those in the maintenance group (mean abstinence, 2.70 [95% CI, 1.72-3.75] vs 5.20 [95% CI, 4.16-6.20] weeks). Patients in the taper group were less likely to complete the trial (6 of 57 [11%] vs 37 of 56 [66%]; P < .001). Sixteen patients in the taper group reinitiated buprenorphine treatment after the taper owing to relapse. CONCLUSIONS AND RELEVANCE: Tapering is less efficacious than ongoing maintenance treatment in patients with prescription opioid dependence who receive buprenorphine therapy in primary care. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00555425.

The feasibility and acceptability of groups for pain management in methadone maintenance treatment.

OBJECTIVES: Effective and safe pain management interventions in methadone maintenance treatment are needed. METHODS: We examined the feasibility (ie, single-session attendance) and acceptability (ie, patient satisfaction and booster session attendance) of cognitive-behavioral therapy-informed groups for pain management-Coping With Pain, Relaxation Training, Group Singing, and Mindful Walking. Pre- and postsession measures were collected. RESULTS: A total of 349 (out of a census of approximately 800) methadone-maintained patients attended at least 1 of the groups. Group satisfaction was high. Booster session attendance was numerically lower in Mindful Walking (14%) than in the other groups (at least 40%). Repeat attendance at Coping With Pain was associated with reduced characteristic pain intensity and depression, whereas repeat attendance at Relaxation Training was associated with decreased anxiety. CONCLUSIONS: Coping With Pain, Relaxation Training, and Group Singing are transportable, affordable, adaptable, and tolerated well by patients with pain and show promise as components of a multimodal pain management approach in methadone maintenance treatment.
