"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

Due to the high cost of health care claims and COBRA's status as remedial legislation, COBRA has generated a significant amount of litigation in recent years. While the early COBRA decisions tended to broaden the law in order to provide a remedy to an otherwise uninsured qualified beneficiary, the recent trend in the case law has been to limit the expansion of COBRA rights based on a narrower construction of the statute. Even so, COBRA still represents a legal minefield for employers. As a result, a careful employer will minimize its exposure by monitoring changes in the law and its interpretation and making appropriate modifications to its COBRA documentation and administration. This article discusses some of the more significant recent changes in the law affecting qualified beneficiaries' COBRA rights--and therefore, employers' exposure.  相似文献

Residential mobility is one documented stressor contributing to higher delinquency and worse educational outcomes. Sensitive period life course models suggest that certain developmental stages make individuals more susceptible to the effects of an exposure, like residential mobility, on outcomes. However, most prior research is observational, and has not examined heterogeneity across age or gender that may inform sensitive periods, even though it may have important implications for the etiology of adolescent development. Moreover, there are important translational implications for identifying the groups most vulnerable to residential mobility to inform how to buffer adverse effects of moving. In this study, low-income families were randomized to residential mobility out of public housing into lower poverty neighborhoods using a rental subsidy voucher (“experimental voucher condition”), and were compared to control families remaining in public housing. The sample was comprised of 2829 youth (51% female; 62% Non-Hispanic Black, 31% Hispanic, 7% other race). At baseline, youth ranged from 5 to 16 years old. This study hypothesized that random assignment to the housing voucher condition would generate harmful effects on delinquency and educational problems, compared to the control group, among boys who were older at baseline. The results confirmed this hypothesis: random assignment to the experimental voucher condition generating residential mobility caused higher delinquency among boys who were 13–16 years old at baseline, compared to same-age, in-place public housing controls. However, residential mobility did not affect delinquency among girls regardless of age, or among boys who were 5–12 years old at baseline. The pattern of results for educational problems was similar but weaker. Families with teenage boys are particularly vulnerable to residential transitions. Incorporating additional supports into housing programs may help low-income, urban families to successfully transition to lower poverty neighborhoods.  相似文献

This paper explores how remittances influence happiness among migrants and their households of origin. It is based on a novel data set of matched samples of Bangladeshi migrant households (living in the UK and Malaysia) and their origin families in Bangladesh. Empirical findings suggest that remittances play a significant role in stimulating migrants’ happiness. We also find that the households of origin’s life satisfaction not only depends on receiving remittances from the emigrants, but also other factors such as number of migrants from the household living abroad and the migrants’ country of destination.  相似文献
