Practical Technology for Expanding and Improving Substance Use Disorder Treatment: Telehealth, Remote Monitoring, and Digital Health Interventions.

The US opioid crisis and the COVID-19 pandemic have sparked innovation in substance use disorder (SUD) treatment such that telehealth, remote monitoring, and digital health interventions are increasingly feasible and effective. These technologies can increase SUD treatment access and acceptability, even for nontreatment seeking, remote, and underserved populations, and can be used to reduce health disparities. Overall, digital tools will likely overcome many barriers to delivery of evidence-based behavioral treatments such as cognitive behavioral therapy and contingency management, that, along with appropriate medications, constitute the foundation of treatment of SUDs.

Thirty Years of TheASAMCriteria: A Report Card.

The American Society of Addiction Medicine Criteria (ASAM) Criteria has profoundly influenced addiction treatment and reimbursement, with its growing toolkit of ASAM CONTINUUM software, ASAM-CARF Level of Care Certification Program, educational programs, and publications. A retrospective accounting shows that the field has made considerable strides, but has far to go. Providers and payers still need to (1) improve consistency in their use of standardized, multidimensional patient assessment; (2) improve flexibility in providing and reimbursing person-centered, individualized services; (3) improve measurement in treatment planning for determination of progress; and (4) focus on outcomes and value in the care they deliver.

Open-label Study of Injectable Extended-release Naltrexone (XR-NTX) in Healthcare Professionals With Opioid Dependence.

OBJECTIVES: Healthcare professionals (HCPs) with opioid dependence are at risk for relapse and death, particularly in the first year of recovery; however, maintenance treatment with opioid agonists is controversial in this safety-sensitive group. We evaluated long-term safety, tolerability, and treatment outcomes of injectable, intramuscular, extended-release naltrexone (XR-NTX) in opioid-dependent HCPs. METHODS: This single-arm, multisite, open-label study was conducted in opioid-dependent HCPs who had been detoxified from opioids for at least 2 weeks. Subjects received monthly XR-NTX injections for up to 24 months, combined with counseling via intensive outpatient substance abuse treatment programs. Assessments included monthly urine opioid drug tests and routine safety assessments, along with a trimonthly short form (36) Health Survey, opioid craving questionnaire, and Treatment Satisfaction Questionnaire for Medication. RESULTS: Of 49 opioid-dependent HCPs screened, 38 enrolled and received at least 1 XR-NTX injection. Most were female (n = 31) and nurses or nursing assistants (n = 30). More than half (n = 21; 55.3%) received at least 12 injections. Seven discontinued due to adverse events (3 anxiety, 2 headache, 1 injection-site mass, 1 derealization). None experienced relapses to opioid dependence necessitating detoxification, overdose, or death during treatment. At 24 months, mean opioid craving fell by 45.2%, and short form (36) mental component scores improved by 31.1% from baseline and approached normal levels. Of 22 unemployed subjects at baseline, 45.5% improved employment status at 24 months. CONCLUSIONS: Long-term (2 years) XR-NTX was associated with no new safety concerns, and, compared with shorter-term studies in the general population, similar or better rates of retention, opioid-negative urines, opioid craving reduction, mental health functional quality of life improvement, and re-employment.

A Naturalistic Evaluation of Extended-Release Naltrexone in Clinical Practice in Missouri.

The purpose of this study was to compare the naturalistic outcomes of individuals with alcohol or opioid use problems who were treated with extended-release naltrexone (XR-NTX) to those treated with psychosocial treatment only and also to those treated with other medication-assisted therapies in Missouri during 2010 to 2011. We analyzed intake and discharge data collected as part of SAMHSA's Treatment Episode Data Set assessments. Patients who received XR-NTX during their treatment episode were compared, for those reporting alcohol (but not opioids) as their problem (N=21,137), to those who received oral naltrexone, acamprosate, and psychosocial treatment only, and for those who reported opioids as a problem (N=8996), to those receiving oral naltrexone, buprenorphine/naloxone, and psychosocial treatment only. Group differences were adjusted using propensity score weighting, with propensity scores derived from 18 intake variables. For the alcohol sample, patients who received XR-NTX vs. the oral naltrexone group had superior composite outcomes on a measure combining abstinence, self-help participation, employment, and arrests. For the opioid sample, XR-NTX was found to have significantly better outcomes than oral naltrexone on the composite outcome measure. For both the alcohol and opioid samples, the group that received XR-NTX stayed in treatment longer vs. psychosocial treatment only. In the opioid sample, those receiving buprenorphine/naloxone remained in treatment longer than those receiving XR-NTX.

Treating Opioid Dependence With Injectable Extended-Release Naltrexone (XR-NTX): Who Will Respond?

OBJECTIVES: Once-monthly intramuscular extended-release naltrexone (XR-NTX) has demonstrated efficacy for the prevention of relapse in opioid dependence, providing an alternative to agonist or partial agonist maintenance (ie, methadone and buprenorphine). The question remains, for whom is this unique treatment most efficacious and can patient-treatment matching factors be identified? METHODS: A moderator analysis was conducted on a previously reported 24-week, placebo-controlled, multisite, randomized controlled trial of XR-NTX (n = 126) versus placebo (n = 124) among recently detoxified opioid-dependent adults in Russia, which showed XR-NTX superior to placebo in proportion of opioid abstinent weeks. The moderator analysis examined a dichotomous indicator of good clinical response-achieving at least 90% of weeks abstinent over the 24-week trial. A series of logistic regression models were fit for this outcome as functions of treatment (XR-NTX vs placebo), each baseline moderator variable, and their interactions. The 25 baseline variables included demographics, clinical severity (Addiction Severity Index, SF-36, and Clinical Global Impression-Severity), functioning (EQ-5D), craving, and HIV serostatus (HIV+). RESULTS: More XR-NTX patients achieved 90% abstinence (64/126, 51%) versus placebo (39/124, 31%; P = 0.002). There were no significant interactions between baseline variables and treatment. There was a significant main effect of Clinical Global Impression-Severity score (P = 0.02), such that higher severity score was associated with a lower rate of Good Clinical Response. CONCLUSIONS: The absence of significant baseline by treatment interactions indicates that no patient-treatment matching variables could be identified. This suggests that XR-NTX was effective in promoting abstinence from opioids across a range of demographic and severity characteristics.

Extended-Release Naltrexone for Alcohol and Opioid Problems in Missouri Parolees and Probationers.

The purpose of this study was to compare the naturalistic outcomes of parolees and probationers with alcohol and/or opioid problems who were treated with extended-release naltrexone (XR-NTX) to those treated with other medication-assisted therapies or psychosocial treatment only. Methods consisted of using intake and discharge data collected as part of SAMHSA's Treatment Episode Data Set (TEDS) assessments, controlling for group differences using propensity scores that were based on a range of intake variables. Results showed that patients receiving XR-NTX had longer durations of care (compared to oral naltrexone and psychosocial treatment only) and were more likely to become abstinent (compared to oral naltrexone, buprenorphine/naloxone, and psychosocial treatment only). Findings were similar for the total sample and those with opioid problems. These XR-NTX results were found in the absence of significant differences in rates of self-help participation. No differences were found in employment or arrests in this relatively short time frame. This study documents the real-world effectiveness study of current FDA-approved addiction medications in parolees/probationers and encourages the use of XR-NTX in such a criminal justice population.

Effects of injectable extended-release naltrexone (XR-NTX) for opioid dependence on residential rehabilitation outcomes and early follow-up.

BACKGROUND AND OBJECTIVES: Little is known about the use of extended-release naltrexone (XR-NTX) during residential rehabilitation, and its effects on early outcomes and rates of follow-up treatment. This study examined patient characteristics and rates of treatment completion and engagement in post-residential care of opioid dependent patients who received XR-NTX during residential rehabilitation, compared with patients who did not receive this medication. METHODS: Electronic records for opioid dependent patients from three Pennsylvania residential detoxification and treatment facilities (N = 7,687) were retrospectively analyzed. We determined the proportion of patients who received XR-NTX (INJ), and compared rates of treatment completion and engagement in follow-up care relative to a naturalistic control group of patients recommended for, but not administered, XR-NTX (Non-INJ). Data on whether the patient initiated follow-up care were available from one site (N = 3,724). RESULTS: Overall, 598 (7.8%) patients were recommended for XR-NTX and of these, 168 (28.1%) received injections. Compared to non-INJ patients, INJ patients were less likely to leave against medical advice (4.8% vs. 30.2%, p < .001) and more likely to initiate follow-up care (37.7% vs. 19.7%, p < .001). These differences remained significant after controlling for demographic covariates using regression analysis. CONCLUSIONS: XR-NTX was associated with higher rates of residential and early post-residential care engagement in patients with opioid dependence. SCIENTIFIC SIGNIFICANCE: XR-NTX may be an effective adjunct in the residential treatment and aftercare of patients with opioid dependence.

A pharmaceutical industry perspective on the economics of treatments for alcohol and opioid use disorders.

Individuals with alcohol and/or drug use disorders often fail to receive care, or evidence-based care, yet the literature shows health economic benefits. Comparative effectiveness research is emerging that examines approved approaches in terms of real, total healthcare cost/utilization. Comprehensive retrospective insurance claims analyses are few but tend to be nationally distributed and large. The emerging pattern is that, while treatment in general is cost effective, specific therapeutics can yield different health economic outcomes. Cost/utilization data consistently show greater savings with pharmacotherapies (despite their costs) versus psychosocial treatment alone. All FDA-approved addiction pharmacotherapies (oral naltrexone, extended-release naltrexone, acamprosate, disulfiram, buprenorphine, buprenorphine/naloxone, and methadone) are intended for use in conjunction with psychosocial management, not as stand-alone therapeutics; hence, pharmacotherapy costs must offer benefits in addition to abstinence alone or psychological therapy. Patient persistence is problematic, and (despite its cost) extended-release pharmacotherapy may be associated with lower or no greater total healthcare cost, mostly due to reduced hospitalization. The reviewed studies use rigorous case-mix adjustment to balance treatment cohorts but lack the randomization that clinical trials use to protect against confounding. Unlike trials, however, these studies can offer generalizability to diverse populations, providers, and payment models--and are of particular salience to payers.

Extended-release naltrexone for alcohol and opioid dependence: a meta-analysis of healthcare utilization studies.

Through improved adherence, once-monthly injectable extended-release naltrexone (XR-NTX) may provide an advantage over other oral agents approved for alcohol and opioid dependence treatment. The objective of this study was to evaluate cost and utilization outcomes between XR-NTX and other pharmacotherapies for treatment of alcohol and opioid dependence. Published studies were identified through comprehensive search of two electronic databases. Studies were included if they compared XR-NTX to other approved medicines and reported economic and healthcare utilization outcomes in patients with opioid or alcohol dependence. We identified five observational studies comparing 1,565 patients using XR-NTX to other therapies over 6 months. Alcohol dependent XR-NTX patients had longer medication refill persistence versus acamprosate and oral naltrexone. Healthcare utilization and costs was generally lower or as low for XR-NTX-treated patients relative to other alcohol dependence agents. Opioid dependent XR-NTX patients had lower inpatient substance abuse-related utilization versus other agents and $8170 lower total cost versus methadone.

Injectable extended-release naltrexone (XR-NTX) for opioid dependence: long-term safety and effectiveness.

AIMS: To describe drug use and safety with intramuscular injectable extended-release naltrexone (XR-NTX) in opioid dependence during a 1-year open-label extension phase. DESIGN: Following 6 months of randomized, double-blind, placebo (PBO)-controlled injections given every 28 days, patients receiving XR-NTX 380 mg continued and PBO patients were switched to open-label XR-NTX, with monthly individual drug counseling, for a further year. SETTING: Thirteen clinical sites in Russia. PARTICIPANTS: Adult opioid-dependent outpatients. MEASUREMENTS: Monthly urine samples; reports of craving and functioning; adverse events. FINDINGS: For the open-label extension (n = 114), 67 continued on XR-NTX and 47 switched from PBO during the double-blind phase to XR-NTX during the open-label phase. Overall, 62.3% (95% CI: 52.7%, 71.2%) completed the extension. Discontinuation occurred most commonly because of withdrawal of consent (18.4%) and loss to follow-up (11.4%); two patients discontinued as a result of lack of efficacy and one because of adverse events. Urine testing revealed that 50.9% (41.5%, 60.4%) were abstinent from opioids at all assessments during the 1-year open-label phase. Adverse events reported by 21.1% of patients were judged to be study drug-related. Injection site reactions were infrequent (6.1%) and the majority were mild. Elevations in liver function tests occurred for 16.7% of patients, but none of these elevations was judged to be clinically significant. No patients died, overdosed or discontinued as a result of severe adverse events. CONCLUSIONS: During a 1-year open-label extension phase of injectable XR-NTX for the prevention of relapse in opioid dependence, 62.3% of patients completed the phase and 50.9% were abstinent from opioids. No new safety concerns were evident.

Opioid challenge evaluation of blockade by extended-release naltrexone in opioid-abusing adults: dose-effects and time-course.

BACKGROUND: Oral naltrexone's effectiveness as an opioid antagonist has been limited due to poor patient adherence. A long-acting naltrexone formulation may be beneficial. This study evaluated the effects of extended-release injectable naltrexone (XR-NTX), targeted for a one-month duration of action, in blocking opioid agonist challenge effects in humans. METHODS: Outpatient non-dependent opioid abusers (N=27) were randomly assigned to a single double-blind IM administration of 75, 150, or 300 mg XR-NTX. To assess the extent of opioid blockade, hydromorphone challenges (0, 3, 4.5, 6 mg IM in ascending order at 1-h intervals [up to 13.5 mg total]) were given at pretreatment baseline and on days 7, 14, 21, 28, 42, and 56. Opioid blockade was assessed via (1) tolerability of the ascending hydromorphone doses; (2) visual analog scale (VAS) ratings of subjective opioid effects and (3) pupil diameter. Effects on the VAS and pupils were assessed via the slope of the time-action function over ascending hydromorphone doses, with zero slope indicating complete blockade. RESULTS: Blockade of the VAS "any drug effect" response to 3 mg hydromorphone was complete for 14, 21, and 28 days, respectively, for the XR-NTX doses of 75, 150, and 300 mg. Subjective effects were more readily blocked than was pupil constriction. Higher hydromorphone doses produced only modest increases in agonist effects. With the 300 mg XR-NTX dose the slope of VAS responses remained at or near zero for one month even with maximal cumulative hydromorphone dosing. CONCLUSIONS: These data quantify the month-long opioid blockade underlying XR-NTX's efficacy in opioid dependence treatment.

Alcohol dependence treatments: comprehensive healthcare costs, utilization outcomes, and pharmacotherapy persistence.

OBJECTIVES: To determine the healthcare costs associated with treatment of alcohol dependence with medications versus no medication and across the 4 medications approved by the US Food and Drug Administration (FDA). STUDY DESIGN: Retrospective claims database analysis. METHODS: Eligible adults with alcohol dependence were identified from a large US health plan and the IMS PharMetrics Integrated Database. Data included all medical and pharmacy claims at all available healthcare sites. Propensity score-based matching and inverse probability weighting were applied to baseline demographic, clinical, and healthcare utilization variables for 20,752 patients, half of whom used an FDA-approved medication for alcohol dependence. A similar comparison was performed among 15,502 patients treated with an FDA-approved medication: oral acamprosate calcium (n = 8958), oral disulfiram (n = 3492), oral naltrexone (NTX) hydrochloride (n = 2391), or extended-release injectable naltrexone (XR-NTX; n = 661). Analyses calculated 6-month treatment persistence, utilization, and paid claims for: alcoholism medications, detoxification and rehabilitation, alcohol-related and nonrelated inpatient admissions, outpatient services, and total costs. RESULTS: Medication was associated with fewer admissions of all types. Despite higher costs for medications, total healthcare costs, including inpatient, outpatient, and pharmacy costs, were 30% lower for patients who received a medication for their alcohol dependence. XR-NTX was associated with greater refill persistence and fewer hospitalizations for any reason and lower hospital costs than any of the oral medications. Despite higher costs for XR-NTX itself, total healthcare costs were not significantly different from oral NTX or disulfiram, and were 34% lower than with acamprosate. CONCLUSION: In this largest cost study to date of alcohol pharmacotherapy, patients who received medication had lower healthcare utilization and total costs than patients who did not. XR-NTX showed an advantage over oral medications in treatment persistence and healthcare utilization, at comparable or lower total cost.

Cost and utilization outcomes of opioid-dependence treatments.

OBJECTIVES: To evaluate the healthcare costs associated with treatment of opioid-dependence disorder with medications versus no medication, and with the 4 agents approved by the US Food and Drug Administration (FDA). STUDY DESIGN: Retrospective claims database analysis. METHODS: Eligible adults with opioid dependence were identified from a large US health plan and the PharMetrics Integrated Database. Data included all medical and pharmacy claims at all available healthcare sites. Case-mix adjustment was applied using baseline demographic, clinical, and healthcare utilization variables for 13,316 patients; half of these patients used an FDA-approved medication for opioid dependence. A similar comparison was performed among 10,513 patients treated with extended-release naltrexone (NTX-XR) (n = 156) prior to FDA approval for opioid dependence or with a medication approved at the time: oral naltrexone (NTX) (n = 845), buprenorphine (n = 7596), or methadone (n = 1916). Analyses calculated 6-month persistence, utilization, and paid claims for opioid-dependence medications, detoxification and rehabilitation, opioid-related and non-related inpatient admissions, outpatient services, and total costs. RESULTS: Medication was associated with fewer inpatient admissions of all types. Despite higher costs for medications, total healthcare costs, including inpatient, outpatient, and pharmacy costs, were 29% lower for patients who received a medication for opioid dependence versus patients treated without medication. Patients given XR-NTX had fewer opioid-related and non-opioid-related hospitalizations than patients receiving oral medications. Despite higher costs for XR-NTX, total healthcare costs were not significantly different from those for oral NTX or buprenorphine, and were 49% lower than those for methadone. CONCLUSION: Patients with opioid dependence who received medication for this disorder had lower hospital utilization and total costs than patients who did not receive pharmacologic therapy. Patients who received XR-NTX had lower inpatient healthcare utilization at comparable or lower total costs than those receiving oral medications.

Injectable extended-release naltrexone for opioid dependence: a double-blind, placebo-controlled, multicentre randomised trial.

BACKGROUND: Opioid dependence is associated with low rates of treatment-seeking, poor adherence to treatment, frequent relapse, and major societal consequences. We aimed to assess the efficacy, safety, and patient-reported outcomes of an injectable, once monthly extended-release formulation of the opioid antagonist naltrexone (XR-NTX) for treatment of patients with opioid dependence after detoxification. METHODS: We did a double-blind, placebo-controlled, randomised, 24-week trial of patients with opioid dependence disorder. Patients aged 18 years or over who had 30 days or less of inpatient detoxification and 7 days or more off all opioids were enrolled at 13 clinical sites in Russia. We randomly assigned patients (1:1) to either 380 mg XR-NTX or placebo by an interactive voice response system, stratified by site and gender in a centralised, permuted-block method. Participants also received 12 biweekly counselling sessions. Participants, investigators, staff , and the sponsor were masked to treatment allocation. The primary endpoint was the response profile for confirmed abstinence during weeks 5­24, assessed by urine drug tests and self report of non-use. Secondary endpoints were self-reported opioid-free days, opioid craving scores, number of days of retention, and relapse to physiological opioid dependence. Analyses were by intention to treat. This trial is registered at ClinicalTrials.gov, NCT00678418. FINDINGS: Between July 3, 2008, and Oct 5, 2009, 250 patients were randomly assigned to XR-NTX (n=126) or placebo (n=124). The median proportion of weeks of confirmed abstinence was 90·0% (95% CI 69·9­92·4) in the XR-NTX group compared with 35·0% (11·4­63·8) in the placebo group (p=0·0002). Patients in the XR-NTX group self-reported a median of 99·2% (range 89·1­99·4) opioid-free days compared with 60·4% (46·2­94·0) for the placebo group (p=0·0004). The mean change in craving was ­10·1 (95% CI ­12·3 to ­7·8) in the XR-NTX group compared with 0·7 (­3·1 to 4·4) in the placebo group (p<0·0001). Median retention was over 168 days in the XR-NTX group compared with 96 days (95% CI 63­165) in the placebo group (p=0·0042). Naloxone challenge confirmed relapse to physiological opioid dependence in 17 patients in the placebo group compared with one in the XR-NTX group (p<0·0001). XR-NTX was well tolerated. Two patients in each group discontinued owing to adverse events. No XR-NTX-treated patients died, overdosed, or discontinued owing to severe adverse events. INTERPRETATION: XR-NTX represents a new treatment option that is distinct from opioid agonist maintenance treatment. XR-NTX in conjunction with psychosocial treatment might improve acceptance of opioid dependence pharmacotherapy and provide a useful treatment option for many patients. FUNDING: Alkermes.

Efficacy of extended-release naltrexone in patients with relatively higher severity of alcohol dependence.

BACKGROUND: Because some literature reviews have suggested that naltrexone's benefit may be limited to less-severe alcohol dependence, and exclusively to reduction in heavy drinking rather than abstinence, we examined the efficacy of once per month, injectable extended-release naltrexone (XR-NTX 380 mg) in patients with relatively higher severity alcohol dependence. METHODS: Post hoc analyses examined data from a multicenter, placebo-controlled, 24-week randomized trial of XR-NTX for alcohol dependence (N = 624). We analyzed treatment effects in alcohol-dependent patients who had higher baseline severity, as measured by: (i) the Alcohol Dependence Scale (ADS) or (ii) having been medically detoxified in the week before randomization. Efficacy was also examined via the relationship between pretreatment severity indices and reporting at least 4 days of lead-in abstinence prior to treatment-a major predictor of good outcome in the original study. RESULTS: Higher severity alcohol-dependent patients, defined by the ADS, when receiving XR-NTX 380 mg (n = 50) compared with placebo (n = 47), had significantly fewer heavy-drinking days in-trial (hazard ratio=0.583; p = 0.0049) and showed an average reduction of 37.3% in heavy-drinking days compared with 27.4% for placebo-treated patients (p = 0.039). Among those who had a detoxification just prior to randomization, these reductions were 48.9% (XR-NTX 380 mg; n = 11) and 30.9% (placebo; n = 15) (p = 0.004). Subjects with at least 4 days of pretreatment abstinence (n = 82) versus those without (n = 542) had significantly higher pretreatment ADS scores (p = 0.002) and were more likely to require detoxification prior to randomization (p < 0.001). Patients with lead-in abstinence experienced significantly better maintenance of initial and 6-month abstinence. CONCLUSIONS: These secondary analyses support the efficacy of XR-NTX 380 mg in relatively higher severity alcohol dependence for both reduction in heavy drinking and maintenance of abstinence, with implications for the role of adherence pharmacotherapy.

Long-term opioid blockade and hedonic response: preliminary data from two open-label extension studies with extended-release naltrexone.

The emergence of extended-release naltrexone (XR-NTX) raises the opportunity to explore the role of endorphin blockade on hedonic response during long-term alcohol dependence treatment. A hedonic survey was administered to 74 alcohol dependent patients treated for an average of 3.5 years with nearly continuous month-long intramuscular XR-NTX. The paper-and-pencil, one-time survey asked patients about the degree of pleasure they experienced in the past 90 days with drinking alcohol, sex, exercise and other daily activities. The data revealed lower pleasure ratings for alcohol than for sex, exercise and 10 other common activities. Mean responses to drinking alcohol and gambling were significantly lower than to listening to music, sex, reading, being with friends, eating good food, eating spicy food, and playing video/card games. This effect was independent of XR-NTX dose or duration. Although this exploratory study lacked baseline data, a comparison group or control for the impact of patient discontinuation, the data indicate the feasibility of examining long-term hedonic response in recovery. The differential hedonic ratings suggest that, in patients who persist with long-term continuous therapy, XR-NTX may selectively inhibit the pleasure associated with drinking alcohol, compared to a variety of other activities.

Intramuscular extended-release naltrexone: current evidence.

Extended-release naltrexone (XR-NTX; Vivitrol), developed to address poor adherence in addictive disorders, is approved for use in alcohol and opioid-dependence disorders. In alcohol-dependent adults with ≥ 4-day initial abstinence, XR-NTX increased initial and 6-month abstinence. An fMRI study found that XR-NTX attenuated the salience of alcohol visual and olfactory cues in the absence of alcohol, and post hoc analyses demonstrated efficacy even during high cue-exposure holiday periods. Safety and tolerability have generally been good, without adverse hepatic impact or intractable acute pain management. XR-NTX use appears feasible in primary care and public systems, and retrospective claims analyses have found cost savings and decreased intensive service utilization relative to oral agents. In opioid dependence, following detoxification, XR-NTX shows efficacy for maintaining abstinence, improving retention, decreasing craving, and preventing relapse. Trials are also exploring its use for the treatment of stimulant dependence. XR-NTX appears compatible with counseling and self-help attendance. While more research is needed, current findings suggest that a formulation of naltrexone that was sought beginning over three decades ago is fulfilling its promise as an extended-release pharmacotherapeutic.

Advancing performance measures for use of medications in substance abuse treatment.

Performance measures have the potential to drive high-quality health care. However, technical and policy challenges exist in developing and implementing measures to assess substance use disorder (SUD) pharmacotherapy. Of critical importance in advancing performance measures for use of SUD pharmacotherapy is the recognition that different measurement approaches may be needed in the public and private sectors and will be determined by the availability of different data collection and monitoring systems. In 2009, the Washington Circle convened a panel of nationally recognized insurers, purchasers, providers, policy makers, and researchers to address this topic. The charge of the panel was to identify opportunities and challenges in advancing use of SUD pharmacotherapy performance measures across a range of systems. This article summarizes those findings by identifying a number of critical themes related to advancing SUD pharmacotherapy performance measures, highlighting examples from the field, and recommending actions for policy makers.

Effects of naltrexone treatment for alcohol-related disorders on healthcare costs in an insured population.

OBJECTIVE: To determine the impact of treatment with oral naltrexone on healthcare costs in patients with alcohol-related disorders. METHODS: Using data from the MarketScan Commercial Claims and Encounters Database for 2000-2004, we identified a naltrexone group (with an alcohol-related diagnosis and at least one pharmacy claim for oral naltrexone) and two control groups. Alcohol controls had an alcohol-related diagnosis and were not prescribed an alcoholism treatment medication. Nonalcohol controls had no alcohol-related diagnosis and no prescription for an alcoholism treatment medication. The control groups were matched three to one to the naltrexone group on demographic and other relevant measures. Healthcare expenditures were calculated for the 6-month periods before and after the index naltrexone drug claim (or matched date for controls). Univariate and multivariate analyses were used to compare the groups on key characteristics and on healthcare costs. RESULTS: Naltrexone patients (n = 1,138; 62% men; mean age 45 +/- 11 years) had significantly higher total healthcare expenditures in the pre-index period than either of the control groups. In the postindex period, naltrexone patients had a significantly smaller increase than alcohol controls in total alcohol-related expenditures. Total nonalcohol-related expenditures also increased significantly less for the naltrexone group than for the alcohol control group. Multivariate analyses showed that naltrexone treatment significantly reduced alcohol-related, nonalcohol-related, and total healthcare costs relative to alcohol controls. CONCLUSIONS: Although prior to treatment patients with alcohol-related disorders had higher healthcare costs, treatment with oral naltrexone was associated with reductions both in alcohol-related and nonalcohol-related healthcare costs.
