Rachel was making her 25th visit to the emergency department. The wound on her leg from injecting drugs had spread to her entire calf and required a lengthy course of antibiotic treatment in the hospital. The few times she had been admitted to the hospital, she had left without finishing treatment because the pain and […]

Over the last two decades, injection opioid use has increased among reproductive-aged women, with resultant increases in mother-to-child hepatitis C virus (HCV) transmissions in the U.S. Direct-acting antiviral (DAA) treatment is highly effective at reducing and eliminating the risk of HCV transmissions. Yet, studies show lower odds of receiving DAA treatment for women compared to […]

Access to health insurance is crucial to gaining the necessary diagnostic and therapeutic services to achieve and maintain good health. Insurance is especially necessary to access medications for opioid use disorder (MOUD) as the cost of MOUD can be a barrier to staying in treatment. If insurance coverage is disrupted, MOUD treatment may be more […]

Direct-acting antivirals (DAAs) have been available since 2015 for hepatitis C (HCV). Nonetheless, very few patients with HCV initiate DAA treatment, ranging from 5% to 30%. The location where a patient is first diagnosed can also influence the care patients receive afterward, especially when a referral to a specialist or coordinated care is needed. In […]

Peer support services (PSS) play an increasingly important role in supporting recovery for people with substance use disorder (SUD). Through these services, peer support workers combine lived experience and professional training to provide health education, encouragement and empathy, recovery modeling, and concrete assistance in overcoming barriers to recovery. As of 2018, 37 Medicaid programs covered PSS for SUD. In a research letter in JAMA Network Open, Dr. Yuhua Bao, professor of population health sciences, and colleagues investigated multi-state utilization of Medicaid-covered PSS in 2019. Researchers found that overall use of Medicaid-covered […]

Individuals with physical health concerns made up the largest and fastest growing of five subgroups of individuals who died by suicide n the United States over roughly twenty years, according to an analysis led by Weill Cornell Medicine in collaboration with Columbia University, UC Berkeley School of Public Health, the University of Hong Kong and […]

While there are highly effective treatments for the hepatitis C virus (HCV), only 1 in 5 Medicaid enrollees diagnosed with HCV started treatment, according to a retrospective study led by researchers at Weill Cornell Medicine and Cornell University’s Ithaca campus. The findings revealed that treatment uptake rates were even lower among people under 30, women, […]

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 […]

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 […]

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. […]
