RESUMO

BACKGROUND: The high rate of attrition along the care cascade of infection with human immunodeficiency virus (HIV) results in lost opportunities to provide timely antiretroviral therapy (ART) and to prevent unnecessarily high mortality. This study aims to assess the effectiveness of a structural intervention, the one-stop ("One4All") strategy that streamlines China's HIV care cascade with the intent to improve testing completeness, ART initiation, viral suppression, and mortality. METHOD: A two-arm, cluster-randomized controlled trial was implemented in twelve county hospitals in Guangxi China to test the effectiveness of the One4All strategy (intervention arm) compared to the current standard of care (SOC; control arm). The twelve study hospitals were selected for homogeneity and allocated one-to-one to the intervention and control arms. All patients screening HIV positive in study hospitals were enrolled. Target study enrollment was 180 participants per arm, 30 participants per hospital. Basic demographic information was collected as well as HIV risk behavior and route of infection. In intervention hospitals, patients then went on to receive point-of-care CD4 testing and in-parallel viral load (VL) testing whereas patients in control hospitals progressed through the usual SOC cascade. The primary outcome measure was testing completeness within 30 days of positive initial HIV screening result. Testing completeness was defined as receipt of all tests, test results, and post-test counseling. The secondary outcome measure was ART initiation (receipt of first ART prescriptions) within 90 days of positive initial HIV screening result. Tertiary outcome measures were viral suppression (≤200 copies/mL) and all-cause mortality at 12 months. DISCUSSION: We expect that this first-ever, cluster-randomized controlled trial of a bundle of interventions intended to streamline the HIV care cascade in China (the One4All strategy) will provide strong evidence for the benefit of accelerating diagnosis, thorough clinical assessment, and ART initiation via an optimized HIV care cascade. We furthermore anticipate that this evidence will be valuable to policymakers looking to elevate China's overall HIV/AIDS response to meet the UNAIDS 90-90-90 targets and the broader, global goal of eradication of the HIV/AIDS epidemic. TRIAL REGISTRATION: ClinicalTrials.gov # NCT02084316 . (Registered on March 7, 2014).

RESUMO

BACKGROUND: Reports suggest increased use of alcohol, prescription drugs, and illicit drugs in Iraq in the past decade, which may portend an increase in substance use disorders (SUDs) and, thus, an increased need for treatments. OBJECTIVES/METHODS: To develop better information on the nature and extent of drug and alcohol use in Iraq, the Iraqi Ministry of Health, with support from the US government and technical assistance from US researchers, held an initial Iraqi Community Epidemiology Work Group meeting in May 2012 in Baghdad. Drug seizure data were the primary data source, provided by Iraqi law enforcement and customs officials. Ministry of Health officials presented data from hospitals (medical and psychiatric), outpatient clinics, and health centers, as well as from surveys of medical patients, pharmacy patients, and prisoners. RESULTS: The data suggest that the most commonly used substances are alcohol, hashish, and prescription drugs. New drugs in Iraq's drug use scene include the amphetamine-type substances "Captagon" and crystal methamphetamine, and the painkiller tramadol. Seizures of Captagon, methamphetamine, Afghan opium, teriac (a crude form of opium), and heroin at border crossings may indicate that these substances are becoming more popular. A plan for an ongoing program of CEWG meetings was developed. CONCLUSIONS: Drug and alcohol use in Iraq is increasing and new drugs are appearing in the country. An ongoing program for monitoring drug use trends and informing Iraqi policy makers is important for public health planning, including the development of strategies to identify citizens with SUDs and provide them treatment.

RESUMO

This study examines the barriers and facilitators of retention among patients receiving buprenorphine/naloxone at eight community-based opioid treatment programs across the United States. Participants (n = 105) were recruited up to three and a half years after having participated in a randomized clinical trial comparing the effect of buprenorphine/naloxone and methadone on liver function. Semi-structured interviews were conducted with 67 patients provided with buprenorphine/naloxone who had terminated early and 38 patients who had completed at least 24 weeks of the trial. Qualitative data were analyzed using the constant comparison method. Barriers to buprenorphine/naloxone retention that emerged included factors associated with: (1) the design of the clinical trial; (2) negative medication or treatment experience; and (3) personal circumstances. The facilitators comprised: (1) positive experience with the medication; (2) personal determination and commitment to complete; and (3) staff encouragement and support. The themes drawn from interviews highlight the importance of considering patients' prior experience with buprenorphine/naloxone and methadone, medication preference, personal circumstances, and motivation to abstain from illicit use or misuse of opioids, as these may influence retention. Ongoing education of patients and staff regarding buprenorphine/naloxone, especially in comparison to methadone, and support from staff and peers are essential.

RESUMO

BACKGROUND: The client population eligible for treatment services supported by State Opioid Response (SOR) grant funding, administered by the Substance Abuse and Mental Health Services Administration (SAMHSA), was expanded to include individuals with a stimulant use disorder (stimUD) in 2020. Due to a significant need to improve services for individuals with stimUD in Montana, the Behavioral Health and Developmental Disabilities Division (BHDD) of the Montana Department of Public Health and Human Services used the grant opportunity to work with experts in the field of stimUD to pilot contingency management (CM) and the Treatment for Individuals who Use Stimulants (TRUST) treatment model. The CM protocol included twice weekly visits for twelve weeks, using an escalating schedule of gift card incentives contingent upon stimulant-negative urine samples. TRUST is a multi-component treatment program, incorporating exercise, group therapy, and individual therapy with content guided by cognitive behavioral therapy (CBT) and clinical research associate (CRA) materials. In addition to SOR dollars, BHDD used additional funding for CM reinforcers provided by state tax dollars to meet research-supported target incentive totals. METHODS: In this pilot project, TRUST/CM was implemented by four state-approved treatment providers and three Federally Qualified Health Centers (FQHCs), all of which had little prior experience with CM as a component of their treatment programs for stimUD. This article examines the processes of training staff, the experiences among staff with initial implementation of the treatment model, and the client characteristics of initial pilot treatment cohorts. Data for this study include primary qualitative data collected from providers, as well as client characteristics collected on the SAMHSA Government Performance and Results Act (GPRA) data collection form. RESULTS: Seven sites were trained in TRUST/CM, and these sites enrolled a total of 70 patients in the program. Qualitative data collected through interviews with site staff revealed the following themes: the value of intensive technical assistance being integrated in the program, concerns about staff retention and loss of expertise, adjustments of target client populations, and the importance of creative strategies for the provision of evidence-informed incentive totals. CONCLUSIONS: TRUST/CM was implemented throughout Montana, including rural and urban communities. Qualitative and quantitative data support that providers viewed the CM component as beneficial for treatment retention and improved outcomes for people with stimUD. These implementation study results provide insight into challenges and solutions for providers who are considering the implementation of CM within either a state-approved substance use treatment clinic or FQHC.

RESUMO

BACKGROUND: Multistage, stepwise HIV testing and treatment procedures can result in lost opportunities to provide timely antiretroviral therapy (ART). Incomplete engagement of patients along the care cascade translates into high preventable mortality. We aimed to identify whether a structural intervention to streamline testing and linkage to HIV health care would improve testing completeness, ART initiation, and viral suppression and reduce mortality. METHODS: We did a cluster-randomised, controlled trial in 12 hospitals in Guangxi, China. All hospitals were required to be level 2A county general hospitals and ART delivery sites. We selected the 12 most similar hospitals in terms of structural characteristics, past patient caseloads, and testing procedures. Hospitals were randomly assigned (1:1) to either the One4All intervention or standard of care. Hospitals were randomised in a block design and stratified by the historical rate of testing completeness of the individual hospital during the first 6 months of 2013. We enrolled patients aged 18 years or older who were identified as HIV-reactive during screening in study hospitals, who sought inpatient or outpatient care in a study hospital, and who resided in the study catchment area. The One4All strategy incorporated rapid, point-of-care HIV screening and CD4 counts, and in-parallel viral load testing, to promote fast and complete diagnosis and staging and provide immediate ART to eligible patients. Participants in control hospitals received standard care services. All enrolled patients were assessed for the primary outcome, which was testing completeness within 30 days, defined as completion of three required tests and their post-test counselling. Safety assessments were hospital admissions for the first 90 days and deaths up to 12 months after enrolment. This trial is registered with ClinicalTrials.gov, number NCT02084316. FINDINGS: Between Feb 24 and Nov 25, 2014, we enrolled 478 patients (232 in One4All, 246 in standard of care). In the One4All group, 177 (76%) of 232 achieved testing completeness within 30 days versus 63 (26%) of 246 in the standard-of-care group (odds ratio 19·94, 95% CI 3·86-103·04, p=0·0004). Although no difference was observed between study groups in the number of hospital admissions at 90 days, by 12 months there were 65 deaths (28%) in the in the One4All group compared with 115 (47%) in the standard-of-care group (Cox proportional hazard ratio 0·44, 0·19-1·01, p=0·0531). INTERPRETATION: Our study provides strong evidence for the benefits of a patient-centred approach to streamlined HIV testing and treatment that could help China change the trajectory of its HIV epidemic, and help to achieve the goal of an end to AIDS. FUNDING: US National Institute on Drug Abuse Clinical Trials Network and China's National Health and Family Planning Commission.

RESUMO

Despite recent advances in behavioral interventions for cannabis use disorders, effect sizes remain modest, and few individuals achieve long-term abstinence. One strategy to enhance outcomes is the addition of pharmacotherapy to complement behavioral treatment, but to date no efficacious medications targeting cannabis use disorders in adults through large, randomized controlled trials have been identified. The National Institute on Drug Abuse Clinical Trials Network (NIDA CTN) is currently conducting a study to test the efficacy of N-acetylcysteine (NAC) versus placebo (PBO), added to contingency management, for cannabis cessation in adults (ages 18-50). This study was designed to replicate positive findings from a study in cannabis-dependent adolescents that found greater odds of abstinence with NAC compared to PBO. This paper describes the design and implementation of an ongoing 12-week, intent-to-treat, double-blind, randomized, placebo-controlled study with one follow-up visit four weeks post-treatment. Approximately 300 treatment-seeking cannabis-dependent adults will be randomized to NAC or PBO across six study sites in the United States. The primary objective of this 12-week study is to evaluate the efficacy of twice-daily orally-administered NAC (1200 mg) versus matched PBO, added to contingency management, on cannabis abstinence. NAC is among the first medications to demonstrate increased odds of abstinence in a randomized controlled study among cannabis users in any age group. The current study will assess the cannabis cessation efficacy of NAC combined with a behavioral intervention in adults, providing a novel and timely contribution to the evidence base for the treatment of cannabis use disorders.

RESUMO

CONTEXT: No randomized trials have examined treatments for prescription opioid dependence, despite its increasing prevalence. OBJECTIVE: To evaluate the efficacy of brief and extended buprenorphine hydrochloride-naloxone hydrochloride treatment, with different counseling intensities, for patients dependent on prescription opioids. DESIGN: Multisite, randomized clinical trial using a 2-phase adaptive treatment research design. Brief treatment (phase 1) included 2-week buprenorphine-naloxone stabilization, 2-week taper, and 8-week postmedication follow-up. Patients with successful opioid use outcomes exited the study; unsuccessful patients entered phase 2: extended (12-week) buprenorphine-naloxone treatment, 4-week taper, and 8-week postmedication follow-up. SETTING: Ten US sites. Patients A total of 653 treatment-seeking outpatients dependent on prescription opioids. INTERVENTIONS: In both phases, patients were randomized to standard medical management (SMM) or SMM plus opioid dependence counseling; all received buprenorphine-naloxone. MAIN OUTCOME MEASURES: Predefined "successful outcome" in each phase: composite measures indicating minimal or no opioid use based on urine test-confirmed self-reports. RESULTS: During phase 1, only 6.6% (43 of 653) of patients had successful outcomes, with no difference between SMM and SMM plus opioid dependence counseling. In contrast, 49.2% (177 of 360) attained successful outcomes in phase 2 during extended buprenorphine-naloxone treatment (week 12), with no difference between counseling conditions. Success rates 8 weeks after completing the buprenorphine-naloxone taper (phase 2, week 24) dropped to 8.6% (31 of 360), again with no counseling difference. In secondary analyses, successful phase 2 outcomes were more common while taking buprenorphine-naloxone than 8 weeks after taper (49.2% [177 of 360] vs 8.6% [31 of 360], P < .001). Chronic pain did not affect opioid use outcomes; a history of ever using heroin was associated with lower phase 2 success rates while taking buprenorphine-naloxone. CONCLUSIONS: Prescription opioid-dependent patients are most likely to reduce opioid use during buprenorphine-naloxone treatment; if tapered off buprenorphine-naloxone, even after 12 weeks of treatment, the likelihood of an unsuccessful outcome is high, even in patients receiving counseling in addition to SMM.
