Since their inception in 1948, The Ethical and Religious Directives for Catholic Health Care Services (ERDs) have guided Catholic health care ministries in the United States, aiding in the application of Catholic moral tradition to modern health care delivery. The ERDs have undergone two major revisions in that time, with about twenty years separating each revision. The first came in 1971 and the second came twenty-six years ago, in 1995. As such, a third major revision is due and will likely be undertaken soon.
