Health care under the jurisdiction of the Texas Department of Criminal Justice has evolved over time to provide prisoners greater access to medical care, including psychiatric care and substance abuse assistance. Mental illness and chronic conditions, such as hypertension, chronic obstructive pulmonary disease, diabetes, and heart disease, are common in prisoners in Texas and across the nation and increase the cost of health care. The average annual health care cost per prisoner in Texas was $4077 in 2015. Although the Texas prison system has undergone changes, such as the use of telemedicine and protocols for preventive measures, to address the varying medical needs of prisoners in correctional facilities, there is still considerable criticism regarding prison policies and incomplete access to medical care. In addition, the ongoing COVID-19 pandemic has added significant stress to correctional health care in Texas and highlights the importance of organized health care for prisoners. This report reviews the history and evolution of health care delivery in Texas's correctional facilities, outlines ongoing efforts to improve medical care in prison facilities, and describes current policies to limit COVID-19 infections in Texas prisons.
