Global epidemiology of hepatitis B and hepatitis C in people who inject drugs: results of systematic reviews
More IDUs have anti-HCV than HIV infection, and viral hepatitis poses a key challenge to public health, which will inform efforts to prevent and treat HCV and HBV in IDUs. Expand
Global epidemiology of injecting drug use and HIV among people who inject drugs: a systematic review
The high prevalence of HIV among many populations of injecting drug users represents a substantial global health challenge and existing data are far from adequate, in both quality and quantity. Expand

HIV prevention, treatment, and care services for people who inject drugs: a systematic review of global, regional, and national coverage
Worldwide coverage of HIV prevention, treatment, and care services in IDU populations is very low, and there is an urgent need to improve coverage of these services in this at-risk population. Expand

Mortality among clients of a state-wide opioid pharmacotherapy program over 20 years: risk factors and lives saved.
Mortality among treatment-seeking opioid-dependent persons is dynamic across time, patient and treatment variables, and despite periods of elevated risk, this large-scale provision of pharmacotherapy is estimated to have resulted in significant reductions in mortality. Expand
Prevention of HIV infection for people who inject drugs: why individual, structural, and combination approaches are needed
Evidence on the effectiveness of individual-level approaches to prevention of HIV infection is summarized, global and regional coverage of opioid substitution treatment, needle and syringe programmes, and antiretroviral treatment is reviewed, and the effect of increased coverage and a combination of these three approaches on HIV transmission and prevalence in injecting drug users is modeled.

Mortality among people who inject drugs: a systematic review and meta-analysis.
Any comprehensive approach to improving health outcomes in this group must include efforts to reduce HIV infection as well as other causes of death, particularly drug overdose, according to the authors. Expand
