The Optimus International Consensus Guidance for Monitoring User-Reported Outcomes of Opioid Maintenance Treatment: A Delphi Study
Opioid use disorder is a major cause of drug-related harm and mortality. These can be reduced by expanded access to evidence-based and highly effective opioid agonist maintenance treatment or therapy (OMT). There is a lack of consensus on how to assess opioid use disorder treatment outcomes, and key health outcomes are often omitted. We report the results of a Delphi study to produce service user- and public health–centred international consensus…
Opioid Agonist Maintenance Treatment Outcomes—The Optimus International Consensus Towards Evidence-Based and Patient-Centred Care, an Interim Report
Non-medical opioid use is a major public health concern causing high mortality. While opioid agonist maintenance treatment (OMT) is a key life-saving intervention, there is (a) no international consensus on opioid treatment outcomes and (b) few opioid treatment outcome studies include key (public) health outcomes, such as overdose or HIV/hepatitis C. We report the rationale and study protocol for, and preliminary results of, an ongoing internatio…

HCV prevalence and risk behaviours among injectors of new psychoactive substances in a risk environment in Hungary—An expanding public health burden
Homelessness and Other Risk Factors for HIV Infection in the Current Outbreak Among Injection Drug Users in Athens, Greece
Objectives. We examined HIV prevalence and risk factors among injection drug users (IDUs) in Athens, Greece, during an HIV outbreak. Methods. We used respondent-driven sampling (RDS) to recruit 1404 IDUs to the Aristotle intervention in August to October 2012. We interviewed participants and tested for HIV. We performed bivariate and multivariate analyses. Results. Estimated HIV prevalence was 19.8% (RDS-weighted prevalence = 14.8%). Odds of infe…
Mortality among people who inject drugs: A systematic review and meta-analysis
A Decade of Spore-Forming Bacterial Infections Among European Injecting Drug Users: Pronounced Regional Variation
The recent anthrax outbreak among injecting drug users (IDUs) in Europe has highlighted an ongoing problem with severe illness resulting from spore-forming bacteria in IDUs. We collated the numbers of cases of 4 bacterial illnesses (botulism, tetanus, Clostridium novyi, and anthrax) in European IDUs for 2000 to 2009 and calculated population rates. Six countries reported 367 cases; rates varied from 0.03 to 7.54 per million people. Most cases (92…
HIV prevention, treatment, and care services for people who inject drugs: A systematic review of global, regional, and national coverage
Meth/amphetamine use and associated HIV: Implications for global policy and public health
Associations Between Availability and Coverage of HIV-Prevention Measures and Subsequent Incidence of Diagnosed HIV Infection Among Injection Drug Users
HIV-prevention measures specific to injection drug users (IDUs), such as opioid substitution treatment and needle-and-syringe programs, are not provided in many countries where injection drug use is endemic. We describe the incidence of diagnosed HIV infection in IDUs and the availability and coverage of opioid substitution and needle-and-syringe programs in the European Union and 5 middle- and high-income countries. Countries with greater provis…
Global epidemiology of injecting drug use and HIV among people who inject drugs: A systematic review
Estimating Local and National Problem Drug Use Prevalence from Demographics
Objective: To assess the applicability and validity of the Multiple Indicator Method for combining sparsely available local prevalence estimates of problem drug use into a national estimate. Method : Local estimates of problem drug use were available in seven out of the 27 addiction treatment regions in the Netherlands. Using demographic variables as predictors and under varying regression model specifications estimates were obtained for the rema…
