Research Highlights

For the last 20 years or so, the U.S. has seen a significant increase in opioid and drug overdoses overall. And while there was a slight leveling before the pandemic, “we’ve seen huge increases since COVID-19,” said Margaret Lowenstein, an LDI Senior Fellow, addiction medicine physician, and an Assistant Professor of Medicine at the Perelman School of […]

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 […]

The United States has made important strides to reduce the incidence and negative outcomes of HIV, including increasing the availability of effective treatment and prevention in the form of pre-exposure prophylaxis (PrEP). While the incidence of new HIV infections fell significantly from 130,000 in 1985, progress has stalled at approximately 39,000 new infections per year […]

Financial incentives are known to increase patient engagement in a wide range of health programs, including programs for maintaining abstinence from substances, attending vaccination and screening appointments, and increasing physical activity. However, they have rarely been used for mental health care beyond treating substance use disorders. Showing up and being involved in mental health treatment […]

Compared to the general population, individuals with opioid use disorder (OUD) who are involved with the criminal-legal system have a much higher risk of a fatal overdose after release from incarceration. Yet, stigma, costs, and preferences for non-narcotic treatments in criminal-legal settings have stalled the implementation of life-saving treatment within the criminal-legal system. Extended-release naltrexone […]

Increased prevalence of illicit substance use during pregnancy in the past decade has renewed national attention to prenatal substance use policies (PSUPs). Currently, there are punitive policies that criminalize drug use during pregnancy or define prenatal substance use as child maltreatment in child welfare statutes. If newborns are found to have prenatal exposure to substances […]

Overdose deaths continue to be a national tragedy. More than 800,000 Americans died from an overdose between 1999-2019, and the annual rate of overdoses has increased dramatically during the pandemic, according to the latest data from the Centers for Disease Control and Prevention. Roughly 7 in 10 current overdose deaths involve opioids, which means that […]

The development of direct-acting antivirals transformed hepatitis C virus (HCV) therapy, allowing patients to experience fewer side effects and non-specialist providers to prescribe HCV treatment with more ease. Despite these advances, existing social and structural barriers, such as stigma and accessibility of medical care, restrict access to effective HCV treatment for people who use drugs […]

In a new study in the American Journal of Emergency Medicine, my colleagues and I estimate the number and distribution of emergency visits for opioid use disorder (OUD) across the country. We found that nearly 2/3 of all emergency visits for OUD occurred in 25% of EDs nationwide. Why is this important? Patients with OUD come to the […]

To date, the American College of Obstetricians and Gynecologists advises pregnant patients not to use cannabis because of the increased risks of health complications to the pregnant individual and the newborn. However, as states expand access to recreational or medical cannabis, there is growing evidence of increased cannabis use and positive perceptions of cannabis among pregnant patients. […]

“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 […]

Naltrexone and buprenorphine are two effective medications for opioid use disorder (OUD). Naltrexone, which is typically given as a monthly extended-release injection (XR-NTX), and daily oral buprenorphine, which is typically combined with naloxone (BUP-NX), are prescribed in outpatient or office-based medical settings. XR-NTX patients, however, need to complete detoxification before starting treatment. Results from a […]
