The Medical Justice Alliance (MJA) is an organization that addresses the significant health challenges faced by the 2 million people who are incarcerated in the US. Many of these people suffer from chronic health conditions and often have unmet acute medical needs due to a lack of resources and infrastructure in the carceral health care system. Since 2004, there has been a 100% increase in the rate of diabetes and a 50% increase in the rate of high blood pressure among people incarcerated in state and federal prisons. In 2020, the pandemic further exacerbated this health crisis, sparking MJA to mobilize volunteer physicians in response. They saw an urgent need to protect the constitutional right to medical care for those who are incarcerated and advocate for compassionate release when appropriate. The organization recruits and trains medical volunteers to offer expert witness services in legal cases and engages in education and advocacy work. To date, it has a staggering case success rate: more than 80% of the incarcerated people served have been released from prison.
