When do health care decisions discriminate against persons with disabilities?

Recent interpretations of laws prohibiting discrimination against persons with disabilities indicate that these laws will play a greater role in health care decision making than previously anticipated. This article employs lessons from other areas of antidiscrimination law to examine these developments and to provide a framework for making health care decisions that are consistent with these new legal interpretations. This article addresses decisions in individual cases, treatment policies adopted by health care providers, and coverage programs of third-party payers, both public and private.

The need for anonymous genetic counseling and testing.

Concerns are mounting about the risks of genetic discrimination resulting from the release of predictive and presymptomatic genetic test results to employers, insurers, and others. The ability to keep this information confidential is questionable, particularly in view of the expansion of electronic medical databases. One solution is to afford individuals access to anonymous genetic counseling and testing. Probands would be identified only by a code that would not reveal personal information, and test results would be stored, retrieved, and released solely on the basis of this code. The experience with anonymous HIV testing, while not completely analogous, suggests that such an approach would be both practical and effective.

A middle stone age worked bone industry from Katanda, Upper Semliki Valley, Zaire.

Three archaeological sites at Katanda on the Upper Semliki River in the Western Rift Valley of Zaire have provided evidence for a well-developed bone industry in a Middle Stone Age context. Artifacts include both barbed and unbarbed points as well as a daggerlike object. Dating by both direct and indirect means indicate an age of approximately 90,000 years or older. Together with abundant fish (primarily catfish) remains, the bone technology indicates that a complex subsistence specialization had developed in Africa by this time. The level of behavioral competence required is consistent with that of upper Paleolithic Homo sapiens sapiens. These data support an African origin of behaviorally as well as biologically modern humans.

The patient-physician relationship and the allocation of scarce resources: a law and economics approach.

Patients with insufficient financial resources place physicians in a conflict of interest between the patients' needs and the financial interests of the physician, other patients, and society. Not only must physicians act ethically, but they must avoid liability for violating their legal duties to their patients. The traditional rules of contract and malpractice law that govern the patient-physician relationship do not provide satisfactory guidelines. Better answers are found in the rules of fiduciary law, but only with regard to direct conflicts between patients and physicians and only at the risk of reducing patient access to care. Certain types of legislative action can resolve these conflicts by altering the traditional legal rules, but care must be taken to preserve patient-physician trust, which the legal rules were designed to enhance.

Coverage of genetic technologies under national health reform.

This article examines the extent to which the technologies expected to emerge from genetic research are likely to be covered under Government-mandated health insurance programs such as those being proposed by advocates of national health reform. Genetic technologies are divided into three broad categories; genetic information services, including screening, testing, and counseling; experimental technologies; and gene therapy. This article concludes that coverage of these technologies under national health reform is uncertain. The basic benefits packages provided for in the major health reform plans are likely to provide partial coverage of experimental technologies; relatively broad coverage of information services; and varying coverage of gene therapies, on the basis of an evaluation of their costs, benefits, and the degree to which they raise objections on political and religious grounds. Genetic services that are not included in the basic benefits package will be available only to those who can purchase supplemental insurance or to those who can purchase the services with personal funds. The resulting multitiered system of access to genetic services raises serious questions of fairness.

Hominid molars from a Middle Stone Age level at the Mumba Rock Shelter, Tanzania.

Three hominid molars were recovered from a depth of 7.0-7.1 meters in the Mumba Shelter at Lake Eyasi, northern Tanzania. Geological context of the finds and archaeological data indicate that people with a Middle Stone Age technology were using the Mumba locality intermittently whenever retreat of lake waters allowed access to the site. Uranium series dates suggest an age on the order of 130,000 years bp for the teeth and stone tools. Based on morphological analyses, the dental remains probably belonged to one individual and appear to be the crowns of two upper permanent M2s and one lower permanent M2. Crown areas are very small, even in comparison to the variation exhibited by recent African populations. Crown patterns have no archaic features. These teeth are smaller than any verifiable archaic Homo sapiens examples; thus, they may represent early anatomically modern Homo sapiens.
