Stepped Care for Patients to Optimize Whole Recovery (SC-POWR): An Effectiveness Trial Evaluating a Stepped Care Model for Individuals With Opioid Use Disorder and Chronic Pain.

Many patients who receive treatment for opioid use disorder (OUD) report experiencing chronic pain (CP), which is associated with high levels of ongoing nonmedical opioid use and low retention in OUD treatment. In pilot studies of patients with OUD receiving buprenorphine or methadone who had CP, cognitive behavioral therapy (CBT) attenuated nonmedical opioid use compared with treatment-as-usual (TAU), but patients in both treatment arms exhibited similar pain improvements. Adding exercise and stress reduction to this model may augment pain-related outcomes. With funding from National Institutes of Health, we plan to conduct a randomized clinical trial of 316 patients with OUD and CP to test the effectiveness of TAU compared with Stepped Care for Patients to Optimize Whole Recovery (SC-POWR) to reduce nonmedical opioid use and pain (primary outcomes) (Aim 1) and decrease pain intensity and interference, alcohol use, anxiety, depression and stress, and improve sleep (secondary outcomes) (Aim 2). Eligible participants will be randomized to receive TAU (buprenorphine or methadone and at least once a month individual or group counseling) or SC-POWR (ie, TAU and up to 12 CBT sessions) for 24 weeks. Based on prespecified nonresponse criteria, SC-POWR may be stepped up at week 6 to receive onsite weekly group sessions of exercise (Wii Fit, Tai Chi) and "stepped up" again at week 15 to receive weekly group sessions of stress reduction (relaxation training, auricular acupuncture). They will be followed for another 24 weeks to evaluate durability of treatment response for illicit opioid use, alcohol use, pain, anxiety, depression, stress, sleep, and retention in medications for OUD (Aim 3).

Spironolactone as a potential new pharmacotherapy for alcohol use disorder: convergent evidence from rodent and human studies.

Evidence suggests that spironolactone, a nonselective mineralocorticoid receptor (MR) antagonist, modulates alcohol seeking and consumption. Therefore, spironolactone may represent a novel pharmacotherapy for alcohol use disorder (AUD). In this study, we tested the effects of spironolactone in a mouse model of alcohol drinking (drinking-in-the-dark) and in a rat model of alcohol dependence (vapor exposure). We also investigated the association between spironolactone receipt for at least 60 continuous days and change in self-reported alcohol consumption, using the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), in a pharmacoepidemiologic cohort study in the largest integrated healthcare system in the US. Spironolactone dose-dependently reduced the intake of sweetened or unsweetened alcohol solutions in male and female mice. No effects of spironolactone were observed on drinking of a sweet solution without alcohol, food or water intake, motor coordination, alcohol-induced ataxia, or blood alcohol levels. Spironolactone dose-dependently reduced operant alcohol self-administration in dependent and nondependent male and female rats. In humans, a greater reduction in alcohol consumption was observed among those who received spironolactone, compared to propensity score-matched individuals who did not receive spironolactone. The largest effects were among those who reported hazardous/heavy episodic alcohol consumption at baseline (AUDIT-C ≥ 8) and those exposed to ≥ 50 mg/day of spironolactone. These convergent findings across rodent and human studies demonstrate that spironolactone reduces alcohol use and support the hypothesis that this medication may be further studied as a novel pharmacotherapy for AUD.

Association of topiramate prescribed for any indication with reduced alcohol consumption in electronic health record data.

BACKGROUND AND AIMS: Topiramate is a medication that is widely prescribed to treat a variety of conditions, including alcohol use disorder (AUD). We used electronic health record (EHR) data to measure topiramate's effects on drinking in individuals differentiated by a history of AUD. DESIGN: Parallel-groups comparison of patients prescribed topiramate and a propensity score-matched comparison group. SETTING: A large US integrated health-care system. PARTICIPANTS: Patients with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) scores prior to and after a minimum of 180 days of topiramate prescription for any indication and a propensity score-matched group. The sample included 5918 patients with an electronic health record diagnosis of alcohol use disorder at any time (AUD-hx-pos) (1738 topiramate-exposed and 4180 controls) and 23 614 patients with no EHR diagnosis of AUD (AUD-hx-neg) (6324 topiramate-exposed and 17 290 controls). MEASUREMENTS: Regression analyses compared difference-in-difference (DiD) estimates, separately by AUD history. DiD estimates represent exposure-group (i.e. topiramate versus control) differences on the pre-post difference in AUDIT-C score. Effects of baseline AUDIT-C score and daily topiramate dosage were also tested. FINDINGS: AUD-hx-neg patients who received topiramate had a greater reduction in AUDIT-C score (-0.11) than matched controls (-0.04). This yielded a DiD score of -0.07 [95% confidence interval (CI) = -0.11,-0.03; P = 0.002], with the greatest effect among AUD-hx-neg patients with a baseline AUDIT-C score of 4+ (DiD = -0.35, 95% CI = -0.49, -0.21; P < 0.0001) and those prescribed > 150 mg/day of the medication (DiD = -0.15, 95%CI = -0.23, -0.07; P < 0.001). DISCUSSION: Among individuals with no history of alcohol use disorder, topiramate appears to be associated with reduced drinking. This small effect is most evident among patients with higher baseline drinking levels and at a higher average daily topiramate dosage.

Mortality, Health, and Substance Abuse by Religious Attendance Among HIV Infected Patients from the Veterans Aging Cohort Study.

Religion and spirituality have been associated with higher survival and improved biological markers among people living with HIV/AIDS (PLWH). Prior results have largely been among small cohort studies. We examined the association using a larger sample and longitudinal data from the Veterans Aging Cohort Study (VACS) years 2002-2012 (n = 3,685). Attending services at least monthly was associated with higher social support (80% vs 75%, p = 0.002), less unhealthy alcohol use (35% vs 39%, p = 0.006), less marijuana use in the past year (23% vs 32%, p < 0.001), less overall drug use within the past year (27% vs 31%, p = 0.01), and lower depression (20% vs 24%, p = 0.004). Attending services monthly was associated with a reduced mortality risk adjusting for age, race, gender, education, MSM, HCV, VL, CD4, and adherence to ARV (adjusted HazardRatio [aHR] = 0.89, 0.80-0.99). However, after controlling for smoking status, this association of mortality and religious attendance became non-significant (aHR = 0.93, 0.84-1.04).

RESUMEN: La religión y la espiritualidad se han asociado con una mayor supervivencia y mejores marcadores biológicos entre las personas que viven con VIH / SIDA (PLWH). Los resultados anteriores han sido en gran parte entre estudios de cohortes pequeñas. Examinamos la asociación utilizando una muestra más grande y datos longitudinales del Estudio de cohorte de envejecimiento de veteranos (VACS) años 2002­2012 (n = 3,685). Asistir a los servicios al menos mensualmente se asoció con un mayor apoyo social (80% frente a 75%, p = 0.002), menos consumo de alcohol no saludable (35% frente a 39%, p = 0.006), menos consumo de marihuana en el último año (23% vs 32%, p < 0.001), menos consumo total de drogas en el último año (27% vs 31%, p = 0.01) y depresión más baja (20% vs 24%, p = 0.004). La asistencia mensual a los servicios se asoció con una reducción del riesgo de mortalidad ajustada por edad, raza, sexo, educación, HSH, VHC, VL, CD4 y adherencia al ARV (HazardRatio ajustado [aHR] = 0.89, 0.80­0.99). Sin embargo, después de controlar el tabaquismo, esta asociación de mortalidad y asistencia religiosa se volvió no significativa (aHR = 0.93, 0.84­1.04).

Integrated stepped alcohol treatment for patients with HIV and at-risk alcohol use: a randomized trial.

BACKGROUND: At-risk levels of alcohol use threaten the health of patients with HIV (PWH), yet evidence-based strategies to decrease alcohol use and improve HIV-related outcomes in this population are lacking. We examined the effectiveness of integrated stepped alcohol treatment (ISAT) on alcohol use and HIV outcomes among PWH and at-risk alcohol use. METHODS: In this multi-site, randomized trial conducted between January 28, 2013 through July 14, 2017, we enrolled PWH and at-risk alcohol use [defined as alcohol consumption of ≥ 14 drinks per week or ≥ 4 drinks per occasion in men ≤ 65 years old or ≥ 7 drinks per week or ≥ 3 drinks per occasion in women or men > 65 years old]. ISAT (n = 46) involved: Step 1- Brief Negotiated Interview with telephone booster, Step 2- Motivational Enhancement Therapy, and Step 3- Addiction Physician Management. Treatment as usual (TAU) (n = 47) involved receipt of a health handout plus routine care. Analyses were conducted based on intention to treat principles. RESULTS: Despite a multi-pronged approach, we only recruited 37% of the target population (n = 93/254). Among ISAT participants, 50% advanced to Step 2, among whom 57% advanced to Step 3. Participants randomized to ISAT and TAU had no observed difference in drinks per week over the past 30 days at week 24 (primary outcome) [least square means (Ls mean) (95% CI) = 8.8 vs. 10.6; adjusted mean difference (AMD) (95% CI) = - 0.4 (- 3.9, 3.0)]. CONCLUSION: An insufficient number of patients were interested in participating in the trial. Efforts to enhance motivation of PWH with at-risk alcohol use to engage in alcohol-related research and build upon ISAT are needed. Trial registration Clinicaltrials.gov: NCT01410123, First posted August 4, 2011.

Integrated stepped alcohol treatment for patients with HIV and liver disease: A randomized trial.

BACKGROUND: There is no known safe level of alcohol use among patients with HIV and liver disease. We examined the effectiveness of integrated stepped alcohol treatment (ISAT) on alcohol use, HIV, and liver outcomes among patients with HIV and liver disease. METHODS: In this multi-site, randomized trial conducted between January 28, 2013 through July 15, 2016, we enrolled 95 patients with HIV and liver disease [defined as having active hepatitis C infection or FIB-4 score > 1.45]. ISAT (n = 49) involved: Step 1- Brief Negotiated Interview with telephone booster, Step 2- Motivational Enhancement Therapy, and Step 3- Addiction Physician Management. Treatment as usual (TAU) (n = 46) involved receipt of a health handout plus routine care. Analyses were conducted based on intention to treat. RESULTS: Among ISAT participants, 55% advanced to Step 2, among whom 70% advanced to Step 3. Participants randomized to ISAT and TAU increased abstinence (primary outcome) over time. Abstinence rates were non-significantly higher by self-report (38% vs. 23%, adjusted odds ratio [AOR] [95% CI] = 2.6 [0.8, 9.0]) and phosphatidylethanol (43% vs. 32%, AOR [95% CI] = 1.8 [0.5, 6.3] among those randomized to ISAT vs. TAU at week 24. VACS Index scores (AMD [95% CI] = 1.1 [-3.2, 5.5]) and the proportion with an undetectable HIV viral load (AOR [95% CI] = 0.3 [0.1, 1.3]) did not differ by group at week 24 (p values >0.05). ISAT had non-significantly lower FIB-4 scores (adjusted mean difference [AMD] [95% CI] = -0.2 [-0.9, 0.5]), ALT (AMD [95% CI] = -7 [-20, 7]) and AST (AMD [95% CI] = -4 [-15, 7]) at week 24 compared to TAU. CONCLUSION: ISAT is feasible and potentially effective at enhancing delivery of evidence-based alcohol treatment to promote alcohol abstinence and improve liver biomarkers among patients with HIV and liver disease.

Cost-effectiveness of integrating buprenorphine-naloxone treatment for opioid use disorder into clinical care for persons with HIV/hepatitis C co-infection who inject opioids.

BACKGROUND: Untreated opioid use disorder (OUD) affects the care of HIV/HCV co-infected people who inject opioids. Despite active injection opioid use, there is evidence of increasing engagement in HIV care and adherence to HIV medications among HIV/HCV co-infected persons. However, less than one-half of this population is offered HCV treatment onsite. Treatment for OUD is also rare and largely occurs offsite. Integrating buprenorphine-naloxone (BUP-NX) into onsite care for HIV/HCV co-infected persons may improve outcomes, but the clinical impact and costs are unknown. We evaluated the clinical impact, costs, and cost-effectiveness of integrating (BUP-NX) into onsite HIV/HCV treatment compared with the status quo of offsite referral for medications for OUD. METHODS: We used a Monte Carlo microsimulation of HCV to compare two strategies for people who inject opioids: 1) standard HIV care with onsite HCV treatment and referral to offsite OUD care (status quo) and 2) standard HIV care with onsite HCV and BUP-NX treatment (integrated care). Both strategies assume that all individuals are already in HIV care. Data from national databases, clinical trials, and cohorts informed model inputs. Outcomes included mortality, HCV reinfection, quality-adjusted life years (QALYs), costs (2017 US dollars), and incremental cost-effectiveness ratios. RESULTS: Integrated care reduced HCV reinfections by 7%, cases of cirrhosis by 1%, and liver-related deaths by 3%. Compared to the status quo, this strategy also resulted in an estimated 11/1,000 fewer non-liver attributable deaths at one year and 28/1,000 fewer of these deaths at five years, at a cost-effectiveness ratio of $57,100/QALY. Integrated care remained cost-effective in sensitivity analyses that varied the proportion of the population actively injecting opioids, availability of BUP-NX, and quality of life weights. CONCLUSIONS: Integrating BUP-NX for OUD into treatment for HIV/HCV co-infected adults who inject opioids increases life expectancy and is cost-effective at a $100,000/QALY threshold.

Racial disparities in discontinuation of long-term opioid therapy following illicit drug use among black and white patients.

BACKGROUND: Among patients prescribed long-term opioid therapy (LTOT) for chronic pain, no study has yet examined how clinicians respond to evidence of illicit drug use and whether the decision to discontinue opioids is influenced by a patient's race. METHODS: Among outpatients of black and white race initiating LTOT through the VA between 2000 and 2010, we reviewed electronic medical records to determine whether opioids were discontinued within 60 days of a positive urine drug test. Logistic regression was used to examine differences by race. RESULTS: Among 15,366 patients of black (48.1%) or white (51.9%) race initiating LTOT from 2000 to 2010, 20.5% (25.5% of blacks vs. 15.8% of whites, P <. 001) received a urine drug test within the first 6 months of treatment; 13.8% tested positive for cannabis and 17.4% for cocaine. LTOT was discontinued in 11.4% of patients who tested positive for cannabis and in 13.1% of those who tested positive for cocaine. Among patients testing positive for cannabis, blacks were 2.1 times more likely than whites to have LTOT discontinued (adjusted odds ratio [AOR] 2.06, 95% confidence interval [CI] 1.04-4.08). Among patients testing positive for cocaine, blacks were 3.3 times more likely than whites to have LTOT discontinued (AOR 3.30, CI 1.28-8.53). CONCLUSIONS: Among patients testing positive for illicit drug use while receiving LTOT, clinicians are substantially more likely to discontinue opioids when the patient is black. A more universal approach to administering and responding to urine drug testing is urgently needed.

Complementary and Alternative Medicine Among Persons living with HIV in the Era of Combined Antiretroviral Treatment.

Complementary and alternative medicine (CAM), often pursued independent of prescribing clinicians, may interact with traditional treatments, yet CAM use has not been well characterized among people living with HIV (PLWH) in the combined antiretroviral therapy (ART) era. We analyzed data from the Veterans Aging Cohort Study (October 2012-April 2015) to characterize CAM use in PLWH on ART. CAM users were more likely to have lived longer with HIV, report more bothersome symptoms, be prescribed more benzodiazepines and opioids, and consume less nicotine and alcohol. Given its high prevalence, clinicians should routinely assess for CAM use and its impact among PLWH.

Association of Cannabis, Stimulant, and Alcohol use with Mortality Prognosis Among HIV-Infected Men.

Questionnaires over a 9-year study period (2002-2010) were used to characterize cannabis, stimulant, and alcohol use among 3099 HIV-infected men participating in the Veterans Aging Cohort Study (VACS) to determine whether use of these substances is associated with changes in the VACS Index, a validated prognostic indicator for all-cause mortality. At baseline, 18% of participants reported no substance use in the past year, 24% lower risk alcohol use only, 18% unhealthy alcohol use only, 15% cannabis use (with or without alcohol), and 24% stimulant use (with or without alcohol or cannabis). In adjusted longitudinal analyses, cannabis use [ß = -0.97 (95% CI -1.93, 0.00), p = 0.048] was not associated with mortality risk, while stimulant use [1.08 (0.16, 2.00), p = 0.021] was associated with an increased mortality risk, compared to lower risk alcohol use. Our findings show no evidence of a negative effect of cannabis use on mortality risk, while stimulant use was associated with increased mortality risk among HIV-infected men. Interventions to reduce stimulant use in this patient population may reduce mortality.

The impact of buprenorphine/naloxone treatment on HIV risk behaviors among HIV-infected, opioid-dependent patients.

BACKGROUND: Opioid dependence is a major risk factor for HIV infection, however, the impact of buprenorphine/naloxone treatment on HIV risk behaviors among HIV-infected opioid-dependent patients is unknown. METHODS: We conducted a longitudinal analysis of 303 HIV-infected opioid-dependent patients initiating buprenorphine/naloxone treatment. Outcomes included self-reported past 90-day needle-sharing and non-condom use. We assessed trends over the 12 months using the Cochran-Armitage trend test. Using generalized estimating equations, after multiple imputation, we determined factors independently associated with needle-sharing and non-condom use, including time-updated variables. We then conducted a mediation analysis to determine whether substance use explained the relationship between time since treatment initiation and needle-sharing. RESULTS: Needle-sharing decreased from baseline to the fourth quarter following initiation of buprenorphine/naloxone (9% vs. 3%, p<0.001), while non-condom use did not (23% vs. 21%, p=0.10). HIV risk behaviors did not vary based on the presence of a detectable HIV-1 RNA viral load. Patients who were homeless and used heroin, cocaine/amphetamines or marijuana were more likely to report needle-sharing. Heroin use fully mediated the relationship between time since treatment initiation and needle-sharing. Women, patients who identified as being gay/lesbian/bisexual, those married or living with a partner and who reported heroin or alcohol use were more likely to report non-condom use. Older patients were less likely to report non-condom use. CONCLUSIONS: While buprenorphine/naloxone is associated with decreased needle-sharing among HIV-infected opioid-dependent patients, sexual risk behaviors persist regardless of viral load. Targeted interventions to address HIV risk behaviors among HIV-infected opioid-dependent populations receiving buprenorphine/naloxone are needed.

Prevalence of mood and substance use disorders among patients seeking primary care office-based buprenorphine/naloxone treatment.

BACKGROUND: Psychiatric comorbidity can adversely affect opioid dependence treatment outcomes. While the prevalence of psychiatric comorbidity among patients seeking methadone maintenance treatment has been documented, the extent to which these findings extend to patients seeking primary care office-based buprenorphine/naloxone treatment is unclear. AIMS: To determine the prevalence of mood and substance use disorders among patients seeking primary care office-based buprenorphine/naloxone treatment, via cross sectional survey. METHODS: 237 consecutive patients seeking primary care office-based buprenorphine/naloxone treatment were evaluated using modules from the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Current (past 30 days) and past diagnoses were cataloged separately. RESULTS: Patients ranged in age from 18 to 62 years old (M=33.9, SD=9.9); 173 (73%) were men; 197 (83%) were white. Major depression was the most prevalent mood disorder (19% current, 24% past). A minority of patients met criteria for current dysthymia (6%), past mania (1%), or past hypomania (2%). While 37 patients (16%) met criteria for current abuse of or dependence on at least one non-opioid substance (7% cocaine, 4% alcohol, 4% cannabis, 2% sedatives, 0.4% stimulants, 0.4% polydrug), 168 patients (70%) percent met criteria for past abuse of or dependence on at least one non-opioid substance (43% alcohol, 38% cannabis, 30% cocaine, 9% sedatives, 8% hallucinogens, 4% stimulants, 1% polydrug, and 0.4% other substances). CONCLUSION: Mood and substance use comorbidity is prevalent among patients seeking primary care office-based buprenorphine/naloxone treatment. The findings support the need for clinicians to assess and address these conditions.

Use of conventional, complementary, and alternative treatments for pain among individuals seeking primary care treatment with buprenorphine-naloxone.

UNLABELLED: Previous studies have not examined patterns of pain treatment use among patients seeking office-based buprenorphine-naloxone treatment (BNT) for opioid dependence. OBJECTIVES: To examine, among individuals with pain seeking BNT for opioid dependence, the use of pain treatment modalities, perceived efficacy of prior pain treatment, and interest in pursuing pain treatment while in BNT. METHODS: A total of 244 patients seeking office-based BNT for opioid dependence completed measures of demographics, pain status (ie, "chronic pain (CP)" [pain lasting at least 3 months] vs "some pain (SP)" [pain in the past week not meeting the duration criteria for chronic pain]), pain treatment use, perceived efficacy of prior pain treatment, and interest in receiving pain treatment while in BNT. RESULTS: In comparison with the SP group (N = 87), the CP group (N = 88) was more likely to report past-week medical use of opioid medication (adjusted odds ratio [AOR] = 3.2; 95% CI, 1.2-8.4), lifetime medical use of nonopioid prescribed medication (AOR = 2.2; 95% CI, 1.1-4.7), and lifetime use of prayer (AOR = 2.8; 95% CI, 1.2-6.5) and was less likely to report lifetime use of yoga (AOR = 0.2; 95% CI, 0.1-0.7) to treat pain. Although the 2 pain groups did not differ on levels of perceived efficacy of prior lifetime pain treatments, in comparison with the SP group, the CP group was more likely to report interest in receiving pain treatment while in BNT (P < 0.001). CONCLUSIONS: Individuals with pain seeking BNT for opioid dependence report a wide range of conventional, complementary, and alternative pain-related treatments and are interested (especially those with CP) in receiving pain management services along with BNT.

Brief versus extended counseling along with buprenorphine/naloxone for HIV-infected opioid dependent patients.

Untreated opioid dependence adversely affects HIV outcomes. Integrating buprenorphine/naloxone into HIV treatment settings is feasible; however, the optimal level of counseling has not been established. We conducted a 12-week randomized clinical trial of physician management (PM) versus PM plus enhanced medical management (EMM) in 47 subjects. At 12 weeks, there were no differences between the two groups in percentage of opioid negative urines (63.6% PM vs. 69.0% PM+EMM, p=.5), maximum duration of continuous abstinence (4.9 weeks PM vs. 5.2 weeks PM+EMM, p=.8) or retention (80% PM vs. 59% PM+EMM, p=.1). The percentage of subjects with detectable HIV viral loads decreased from 58% at baseline to 40% at 12 weeks across both groups (p=.02 for time) with no between group differences (p=.84 and p=.27 for the interaction). Providing more extensive counseling beyond PM is feasible in an HIV clinic, but we are unable to detect an improvement in outcomes associated with these services.

Cost-effectiveness of long-term outpatient buprenorphine-naloxone treatment for opioid dependence in primary care.

BACKGROUND: Primary care physicians with appropriate training may prescribe buprenorphine-naloxone (bup/nx) to treat opioid dependence in US office-based settings, where many patients prefer to be treated. Bup/nx is off patent but not available as a generic. OBJECTIVE: We evaluated the cost-effectiveness of long-term office-based bup/nx treatment for clinically stable opioid-dependent patients compared to no treatment. DESIGN, SUBJECTS, AND INTERVENTION: A decision analytic model simulated a hypothetical cohort of clinically stable opioid-dependent individuals who have already completed 6 months of office-based bup/nx treatment. Data were from a published cohort study that collected treatment retention, opioid use, and costs for this population, and published quality-of-life weights. Uncertainties in estimated monthly costs and quality-of-life weights were evaluated in probabilistic sensitivity analyses, and the economic value of additional research to reduce these uncertainties was also evaluated. MAIN MEASURES: Bup/nx, provider, and patient costs in 2010 US dollars, quality-adjusted life years (QALYs), and incremental cost-effectiveness (CE) ratios ($/QALY); costs and QALYs are discounted at 3% annually. KEY RESULTS: In the base case, office-based bup/nx for clinically stable patients has a CE ratio of $35,100/QALY compared to no treatment after 24 months, with 64% probability of being < $100,000/QALY in probabilistic sensitivity analysis. With a 50% bup/nx price reduction the CE ratio is $23,000/QALY with 69% probability of being < $100,000/QALY. Alternative quality-of-life weights result in CE ratios of $138,000/QALY and $90,600/QALY. The value of research to reduce quality-of-life uncertainties for 24-month results is $6,400 per person eligible for treatment at the current bup/nx price and $5,100 per person with a 50% bup/nx price reduction. CONCLUSIONS: Office-based bup/nx for clinically stable patients may be a cost-effective alternative to no treatment at a threshold of $100,000/QALY depending on assumptions about quality-of-life weights. Additional research about quality-of-life benefits and broader health system and societal cost savings of bup/nx therapy is needed.

Participant characteristics and HIV risk behaviors among individuals entering integrated buprenorphine/naloxone and HIV care.

OBJECTIVE: This study was part of a national, multisite demonstration project evaluating the impact of integrated buprenorphine/naloxone treatment and HIV care. The goals of this study were to describe the baseline demographic, clinical, and substance use characteristics of the participants and to explore HIV transmission risk behaviors in this group. METHODS: Nine sites across the United States participated. Data obtained by interview and chart review included demographic information, medical history, substance use, and risk behaviors.We performed a descriptive analysis of patient characteristics at entry and used logistic regression to evaluate factors associated with 1) unprotected anal or vaginal sex; and 2) needle-sharing within the previous 90 days. RESULTS: Three hundred eighty-six individuals were included in the study: 303 (78.5%) received buprenorphine/naloxone; 41 (10.6%) received methadone; and 42 (10.9%) received another form of treatment. The analysis of risk behaviors was limited to those in the buprenorphine group (n = 303). Among those reporting vaginal or anal sex in the previous 90 days, 24% had sex without a condom. Factors significantly associated with unprotected sex were: having a partner; female gender; and alcohol use in previous 30 days. A total of 8.9% of participants shared needles in the previous 90 days. Factors significantly associated with needle-sharing were: amphetamine use; marijuana use; homelessness; and anxiety. CONCLUSIONS: Addressing transmission risk behaviors is an important secondary HIV prevention strategy. In addition to treatment for opioid dependence, addressing other substance use, social issues, particularly housing, and mental health may have important implications for reducing HIV transmission in HIV-infected opioid-dependent patients.

Integration of buprenorphine/naloxone treatment into HIV clinical care: lessons from the BHIVES collaborative.

BACKGROUND: Replication of effective practices requires detailed descriptions of implementation processes, barriers and facilitators, and lessons learned. The experiences of physicians leading the Buprenorphine HIV Evaluation and Support initiative provides valuable information for other HIV providers seeking to integrate medication-assisted treatment services into HIV clinical care. METHODS: Evaluation staff conduced site visits to the 10 funded Buprenorphine HIV Evaluation and Support programs to better understand buprenorphine/naloxone (bup/nx) integration practices; services offered; staffing; provider experiences with and perceptions of bup/nx; perceived barriers, facilitators, and sustainability; and recommendations regarding replication of integrated care program components. Interviews with site principal investigators conducted during the last year of program implementation were transcribed, coded, and analyzed according to both pre-identified and emerging themes. RESULTS: Integrated bup/nx and HIV treatment was successfully introduced to community and hospital-based clinics under the direction of infectious disease, psychiatry, and general internal medicine physicians. All but 1 of the principal investigators interviewed were highly satisfied with integrated HIV and bup/nx treatment, and all anticipated continued provision of the service. Multiple prescribers were necessary to ensure sufficient coverage and a bup/nx coordinator (eg, nurse, counselor) was seen as essential to the provision of quality care. Ongoing challenges included multisubstance use and mental health issues among patients; limited adoption of bup/nx treatment among colleagues; and the necessity of incorporating new procedures, including urine toxicology testing into established practice. CONCLUSIONS: Findings suggest that integrated bup/nx treatment and HIV care is acceptable to providers and feasible in a variety of practice settings.

The cost of integrated HIV care and buprenorphine/naloxone treatment: results of a cross-site evaluation.

BACKGROUND: Implementing integrated HIV and buprenorphine/naloxone treatment requires cost estimates to plan and obtain funding. METHODS: We identified costs incurred at HIV clinical sites participating in a cross-site evaluation of integrated care that followed patients for 1 year. Costs include labor, overhead, and urine toxicology analyses (clinic perspective), buprenorphine/naloxone (payer perspective) and patient time and transportation (patient perspective). Sites provided resource utilization quarterly, and providers estimated time required for each activity. With site as the unit of analysis, results are reported as median (range) of average site costs in 2008 US dollars. RESULTS: The median number of monthly provider encounters for integrated care patients was 3.2 (1.5-13.3) compared with 1.7 (1.1-4.2) for similar patients not in integrated care, but integrated care patients had fewer physician encounters. Median monthly clinic costs per integrated care patient were $136 ($67-$677) for labor and overhead and $8 ($2-$23) for toxicology analyses, $22 higher than clinic costs for patients not in integrated care. Median monthly costs for buprenorphine/naloxone were $209 ($165-$272), and monthly patient costs in integrated care were $11 ($1-$54) higher. CONCLUSIONS: Integrated HIV and buprenorphine/naloxone treatment requires different resources, including costs that are not third-party reimbursed. Implementing integrated care will require funding for training and for new staff such as buprenorphine coordinators, in addition to reimbursement for buprenorphine/naloxone. Further research is needed to identify potential cost offsets outside of the clinic setting.

Buprenorphine and HIV primary care: new opportunities for integrated treatment.

Drug abuse and infection with human immunodeficiency virus (HIV) are associated with high rates of morbidity and mortality, but, because of medical, social, and legal factors, opiate addiction/dependence is a major obstacle to successful treatment of disease--for example, treatment of acquired immunodeficiency syndrome (AIDS) with highly active antiretroviral therapy. In an effort to improve the opportunity for treatment of drug abuse and HIV infection, the Forum for Collaborative HIV Research, in collaboration with the Substance Abuse and Mental Health Services Administration, the National Institute on Drug Abuse, the Centers for Disease Control and Prevention, and other agencies, presented a workshop entitled "Buprenorphine in the Primary HIV Care Setting." Participants reviewed and discussed current issues, such as the introduction of and sources for the provision of buprenorphine in HIV primary care settings and strategies for integrating treatment of HIV-infected drug abusers, all of which are covered in this supplement.
