With Bill Clinton's new reforms only a month away, the health-care system is on the operating table--and the doctors are under the knife. Americans have a love-hate relationship with physicians: they like the care that doctors provide but hold them to blame for the nation's health-care mess. NEWSWEEK looks at how the culture of medicine may change, assesses doctors' fears--and examines the brave new world of HMOs.  相似文献

This article builds a composite index, the Central American Integration Index (IIC-AMPI), to measure economic integration. This index utilises a robust methodology and conceptual framework. The study shows that IIC-AMPI is responsive to variable changes and resistant to outliers. The findings indicate that the Deep Integration Process initiative dominates the current integration trend, as seen in the regional average score from 2015 to 2017, aligning with Guatemala and Honduras. Nicaragua demonstrates the most consistent progress, while Panama lags behind. The evidence supports the Customs Union as Central America's future integration path, highlighting the index's ability to capture the dynamic reality of economic integration.  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

The present research explored factors thought to affect compensatory awards for non-economic ham (pain and suffering) in personal injury cases. Experiment 1 showed that the nature and severity of the plaintiffs injury had a strong effect on perceptions of the extent of harm suffered and on award amounts. The parties' relatively active or passive roles in causing the injury affected assessments of their degree of fault, but perceived fault had little influence on awards. Experiment 2 replicated with more varied cases the strong impact of injury severity on harm perception and on awards for pain and suffering. In both studies, the disability and the mental suffering associated with injuries were stronger predictors of awards than were pain and disfigurement.  相似文献
