Cost effectiveness of disulfiram: treating cocaine use in methadone-maintained patients.

Converging evidence suggests that disulfiram is a promising treatment for cocaine dependence. We study the cost-effectiveness of providing disulfiram to methadone-maintained opioid addicts in a randomized clinical trial setting. Our economic evaluation is based on a double blind clinical trial in which 67 cocaine-dependent methadone-maintained opioid-dependent subjects were randomized to get the additional treatment of disulfiram or placebo in a 12-week trial. Outcome measures used are the number of days of cocaine use and grams of cocaine per week. Cost measures used are the cost of providing standard methadone treatment and the incremental cost of adding disulfiram to the standard treatment. Cost measures of standard and disulfiram-enhanced treatment were collected retrospectively from the provider. Results from this cost-effectiveness analysis imply that, even though disulfiram increases slightly the cost of methadone treatment, its increase in effectiveness may be important enough to warrant its addition for treating cocaine dependence in methadone-maintained opiate addicts

Prevalence, risk and protective factors of alcohol use disorder during the COVID-19 pandemic in U.S. military veterans

BackgroundThere have been reports of increased alcohol consumption during the COVID-19 pandemic in the general population. However, little is known about the impact of the pandemic on the prevalence of alcohol use disorder (AUD), especially in high-risk samples such as U.S. military veterans.MethodsData were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative, prospective cohort of 3078 U.S. veterans. Pre-pandemic and 1-year peri-pandemic risk and protective factors associated with incident and chronic probable AUD were examined.ResultsA total of 6.9 % (n = 183) of veterans were classified as chronic probable AUD, 3.2 % (n = 85) as remitted from AUD, and 2.7 % (n = 71) as incident probable AUD during the pandemic; the prevalence of probable AUD in the full sample remained stable -10.1 % pre-pandemic and 9.6 % peri-pandemic. Younger age, greater pre-pandemic alcohol use severity, and COVID-related stressors were associated with incident AUD during the pandemic, whereas higher pre-pandemic household income was associated with lower risk of this outcome. Younger age, combat experience, lifetime substance use disorder, greater drug use severity, lower dispositional optimism, and more COVID-related worries and social restriction stress were associated with higher risk of chronic AUD.ConclusionsNearly 1-in-10 US veterans screened positive for AUD 1-year into the pandemic; however, the pre- and 1-year peri-pandemic prevalence of probable AUD remained stable. Veterans who are younger, have served in combat roles, endorse more COVID-related stressors, and have fewer socioeconomic resources may be at higher risk for AUD during the pandemic

Substance use and schizophrenia: Adverse correlates in the CATIE study sample

This study examined the relationship between severity of illicit substance use at the time of study entry in a sample of patients diagnosed with schizophrenia and 18-month longitudinal outcomes, including psychopathology, depression, neurocognition, and quality of life. Subjects in the Clinical Antipsychotic Trials of Intervention Effectiveness (N=1432) were divided into three groups according to baseline data: (1) those with moderate/severe drug use, (2) those with mild drug use, and (3) non-users of illicit substances. The groups were compared on other baseline characteristics. Mixed model analysis was used to compare outcomes between the groups using all available outcome data over 18months, controlling for potential confounding baseline characteristics. Least square means were compared between pairs of groups in the mixed models. Significantly poorer outcomes were observed in the domains of psychosis, symptoms of depression, and quality of life for moderate/severe drug users in comparison with both mild users and abstainers. No significant differences were found on neurocognitive functioning or days of employment. This study suggests that drug use-related impairment co-morbid with schizophrenia may not be a function of use per se but rather, of the severity of use. It highlights the importance of comprehensive assessment and treatment of illicit substance abuse in schizophrenia. Long-term treatment approaches that integrate harm reduction strategies may offer promise in maximizing positive outcomes for such dually diagnosed patients
