Background The total population health benefits and costs of HIV preexposure prophylaxis (PrEP) for people who inject drugs (PWID) in the United States are unclear. Objective To evaluate the cost-effectiveness and optimal delivery conditions of PrEP for PWID. Design Empirically calibrated dynamic compartmental model. Data Sources Published literature and expert opinion. Target Populatio...

AIMS To determine the impact of HIV infection on mortality over time among people who inject drugs (PWID) in settings with free HIV/AIDS care. DESIGN AND SETTING Prospective cohort study of PWID in Vancouver, Canada, recruited between May 1996 and December 2011. We ascertained morality rates and causes of death through a confidential linkage with the provincial vital statistics registry. PA...

BACKGROUND Most hepatitis C virus (HCV) infections in the United States occur following non-sterile injection drug use. However, the majority of people who inject drugs (PWID) with chronic HCV are not currently receiving care. OBJECTIVE This paper presents our protocol for the systematic review and meta-analysis of data on the natural history of HCV among PWID and will inform modeling of the ...

BACKGROUND Hepatitis C virus (HCV) infection represents a major global health problem, which in high-income countries now mostly affects people who inject drugs (PWID). Many studies show that the treatment of HCV infection is as successful among PWID as among other populations and recently PWID have been included in the international guidelines for the treatment of HCV infection. The aim of thi...

BACKGROUND The perspectives of people who use drugs are critical in understanding why people choose to reduce harm in relation to drug use, what practices are considered or preferred in conceptualizations of harm reduction, and which environmental factors interfere with or support the use of harm reduction strategies. This study explores how people who inject drugs (PWID) think about harm reduc...

We reviewed published national HIV care continua for men who have sex with men (MSM), people who inject drugs (PWID), and female sex workers (FSWs) to track progress toward the 90-90-90 target. We searched the Internet, PubMed, surveillance reports, United Nations Programme on HIV/AIDS country reports, US President’s Emergency Plan for AIDS Relief country/ regional operational plans, and confer...

Abstract Background We evaluated the impact of a brief, peer-led intervention on COVID-19 vaccination among people who inject drugs (PWID) presenting at syringe services program (SSP) locations in San Diego County, California. Methods Between March and July 2022, PWID aged ≥18 years old without recent voluntary testing were not up to date vaccinations received single-session motivational interv...

The recent, and rapid, emergence of injection of the short-acting stimulant mephedrone (4-methylmethcathione) has resulted in concerns about increased infection risks among people who inject drugs (PWID). Data from the bio-behavioural surveillance of PWID in the United Kingdom were analysed to examine the impact of mephedrone injection on infections among PWID. During the year preceding the sur...

INTRODUCTION High rates of hepatitis C virus (HCV) transmission are found in samples of people who inject drugs (PWID) throughout the world. The objective of this paper was to meta-analyze the effects of risk-reduction interventions on HCV seroconversion and identify the most effective intervention types. METHODS We performed a systematic review and meta-analysis of published and unpublished ...

INTRODUCTION AND METHODS Hepatitis C virus (HCV) infections are highly prevalent amongst people who inject drugs (PWID). Despite well documented evidence of its effectiveness, suggested cost-effectiveness, and potential to reduce HCV prevalence rates, the uptake of antiviral HCV treatment by PWID is low. This nonsystematic literature review describes factors associated with the uptake, adherenc...
