Drug overdose deaths continue to rise in the United States and Canada, with the risks for greater opioid use sharply increasing in Mexico. As modelers, we know simulation modeling is a valuable tool that can inform policies and interventions to prevent overdose deaths and reduce related harms including drug overdose, HIV, and hepatitis C virus […]

“What will it take to end HIV in the United States?” is a pressing question posed by public health officials, researchers, and policymakers alike. Population Data & Modeling Core Director Benjamin Linas seeks to answer that question by amplifying notable results from a simulation modeling study published by researchers at Johns Hopkins. In an editorial issued in the Annals of […]

COVID-19 has brought simulation modeling to the foreground of public discourse, as policy makers and stakeholders project the effects of different interventions to “flatten the curve.” Simulation models allow investigators to tinker with different conditions of the world to observe how they affect future outcomes; however, translating the models’ results to the public can be […]

Injection-related infective endocarditis (IE) is a serious and expensive medical complication among people who inject drugs (PWID). In some states, such as North Carolina there has been a 12-fold increase in injection-related IE between 2007 and 2017. Approximately 1.3% of people who inject drugs report IE within the past year, and between 0.5% and 11.8% report IE […]

Although there are several evidence-based cost-effective interventions for people with opioid use disorder (OUD), they are underutilized. Questions remain regarding intervention selection, and cost of service delivery. Simulation modeling offers an opportunity to support decision making to address the syndemic of opioid overdose, HIV, and hepatitis C (HCV). In an article recently published in the International Journal […]

In 2019, the United States launched the effort to End the HIV Epidemic by reducing new infections by 75% within 5 years and by 90% within 10 years. This national strategy comes with some new funding for the Centers of Disease Control and Prevention (CDC), the Health Resources and Services Administration (HRSA), and the Ryan White HIV/AIDS […]

The proportion of hospital admissions for endocarditis attributable to injection drug use increased from 7% in 2000 to 12% in 2013. Endocarditis is an infection in the lining of the heart chambers and valves that can be contracted through shared injection equipment. Rates of endocarditis are disproportionately affecting young people who inject drugs (PWID), which has […]

The incidence of neonatal abstinence syndrome (NAS), also known as neonatal withdrawal syndrome, increased nationally from 3.4 per 1000 hospital births in 2009 to 5.8 in 2012. Recent estimates of NAS cost $1.5 billion dollars with the majority of the financial burden falling to state Medicaid programs. However, pregnancy offers a unique opportunity for women with […]

The US Preventive Services Task Force (USPSTF) released a draft recommendation for hepatitis C (HCV) antibody and RNA screening in all adults ages 18 to 79. This is a departure from their current 2013 recommendation of risk-based screening, including people who inject drugs (PWID), and one-time screening in baby boomers born between 1945 and 1965.  The recommendation […]

People who inject drugs (PWID) often become infected with HIV and hepatitis C virus (HCV). While hepatitis C can be successfully treated with medication, care is often fragmented and rarely integrated within one program or setting. Two recent studies by CHERISH researchers modeled economic and health outcomes for PWID and found evidence of synergistic benefits […]
