very year in the United States, approximately 1200 residents graduate from obstetrics and gynecology residency programs. 1 In 2016, there were 246 such programs whose accreditation is provided by the Accreditation Council for Graduate Medical Education (ACGME). 1 To achieve and maintain accreditation, these programs must meet program requirements (PRs) laid out in the ACGME Program Requirements for Graduate Medical Education in Obstetrics and Gynecology. 2 Of these programs, approximately 14% are sponsored by Catholic institutions, and it is estimated that about 1 in 14 obstetrician-gynecologists in the United States have graduated from programs under Catholic sponsorship. 3 Due to mergers and changes in ownership of many hospitals and health care systems, 4 the exact number of programs under Catholic sponsorship is difficult to determine on an annual basis. However, as Catholic ownership or affiliation of hospitals in this country is increasing, 4,5 it is reasonable to conclude that a significant portion of postgraduate training in obstetrics and gynecology occurs in academic centers that are under Catholic sponsorship. Catholic health care services also have requirements to achieve and maintain full cooperation with the moral and theological foundations of the Catholic Church. These requirements are elucidated as directives in the Ethical and Religious Directives for Catholic Health Care Services (ERDs) issued by the United States Conference of Catholic Bishops and most recently updated in 2018. 6 The ERDs are intended to offer guidance for the administration, medical professionals, patients, chaplaincy, and sponsoring trustees in the institutional operations of the Catholic health care entity. Additionally, it is expected that, as a matter of employment or granting of health care privileges within a Catholic health care system, adherence to the ERDs occurs on institutional, employee, and clinician levels. 6 Specific to the scope of practice of obstetrics and gynecology, the ERDs prohibit direct abortion, sterilization, contraceptive practice, in vitro fertilization, and preimplantation genetic diagnosis in Catholic health care institutions. 6 The implications extend to other specialty programs
