As the administration of President Donald Trump gears up to hold more migrants in detention facilities for longer periods of times, health care and medical professionals are raising concerns and proposing changes to the way federal agencies provide medical treatment to immigrant detainees.

Dr. Paul Spiegel, director of the Center for Humanitarian Health at Johns Hopkins, argued in a commentary piece published Friday in the Journal of the American Medical Association (JAMA) that the way in which the government provides health care services to migrants who have been detained goes against the oath physicians take to make patients’ well-being their top priority.
