Homeless persons prefer more aggressive medical care than the physicians making decisions for them, which may result in treatment preferences of homeless persons being overlooked. A new study published in the June issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians, reports that homeless persons are more likely than physicians to want lifesaving procedures performed on them. As a result, homeless persons who must rely on physicians as surrogate decision makers for medical care may receive less aggressive treatment than they would choose for themselves.
