The medical capabilities derived from modern reproductive technology, such as in vitro fertilization and cryopreservation, have enabled physicians and scientists to intervene in the procreative process in innumerable ways. However, this intervention in the natural reproductive process raises both moral and legal concerns. In this Article, Professor Schiff explores some of the conflicts that may result when an individual or couple elects to cryopreserve gametes or embryos and subsequently, one or both of the contributors dies, or when gametes are harvested from a dead body. This Article will specifically address the moral and legal responses to circumstances where the decedent has either clearly expressed opposition to posthumous use of the reproductive material or else the decedent's intent regarding posthumous use of the material is ambiguous. By discussing philosophical and moral positions relating to personhood and the body and analyzing legal issues such as reproductive choice and organ donation, Professor Schiff creates the necessary format to examine and recommend the proper legal treatment of this controversial aspect of posthumous procreation.  相似文献

"Whatever, in connection with my professional practice, or not in connection with it, I see or hear, in the life of men, which ought not to be spoken of abroad, I will not divulge, as reckoning that all such should be kept secret."(1) "Safeguards to privacy in individual health care information are imperative to preserve the health care delivery relationship and the integrity of the patient record."(2) As early as the fourth and fifth centuries B.C., Hippocrates contemplated the importance of medical information to the care and treatment of patients. His oath suggests that privacy of a patient's medical information creates the foundation upon which a patient reposes trust in his or her physician. While defining the earliest version of the physician-patient privilege, the oath does not envision the extent of modern day access to healthcare information. A patient's relationship with the modern healthcare delivery system often includes a team of physicians, nurses, and other clinical support personnel. This relationship extends beyond direct caregivers and may include healthcare administrators, payor organizations, and persons unfamiliar with a patient's identity, such as researchers and public health officials. Accessing a patient's medical information links these participants to the patient's healthcare delivery relationship. The Hippocratic Oath does not contemplate such broad access, nor does it contemplate the emerging privacy crisis resulting from the application of computer technology to medical record storage and retrieval. The combination of broad access, individual privacy rights, and computer technology requires a rethinking of measures designed to protect the realities of the modern medical information society.  相似文献

This Note discusses the potential for genetic discrimination, current views as to whether genetic conditions will be covered by the Americans with Disabilities Act ("ADA"), and the specific issue of whether presymptomatic persons who test positive for Huntington's disease should be classified as persons with a "disability" within the meaning of the ADA. In considering whether presymptomatic Huntington's individuals have a disability under the ADA, an analogy is made between Huntington's disease and HIV-positive status. Inter alia, Huntington's disease and HIV-positive status are analogous in that, at the time of diagnosis, victims of both diseases may have no symptoms and may remain healthy for a number of years; but even though the exact time of onset of both diseases is unascertainable, death of both victims within a given range of years is highly likely. Further, both Huntington's disease and HIV are transmitted to offspring at a relatively high rate. Given these similarities, the author argues that Huntington's individuals should be afforded the protections of the ADA for the same reasons that HIV-positive persons are protected.  相似文献

This article will trace the history and effects of the PPI from the time of its original concept by the FDA in the early 1970's to its current status. It will also address the response to this FDA initiative by the industry, medical community and consumer groups. Initiatives in other countries and future issues will also be discussed.  相似文献

The United States Supreme Court agreed with the Secretary of Health and Human Services that Guernsey Memorial Hospital's advance refunding transaction costs would be subject to a medicare reimbursement policy that is not based upon generally accepted accounting principles. According to the sharp dissent in this case, this policy, set forth in a manual provision, contradicts federal regulations.  相似文献
