To better understand the impact of changing health care delivery on the workers' compensation system and the cost of treating injured workers, the author examines the program within the context of recent environmental changes--including the likely impact of managed care. 相似文献

EBCT measured coronary calcium is fast becoming a standard screening tool in asymptomatic patients with and without risk factors who apply for life insurance. Since atherosclerotic plaques become calcified as part of their natural history, the calcium score is an excellent measure of total atherosclerotic burden. Over the past 5 years, various clinical studies have confirmed the predictive value of the coronary calcium score for both soft (revascularization, MI) and hard (MI and sudden cardiac death) events incrementally and independently of traditional coronary risk factors identified by the Framingham Heart Study. Accurate assessment of cardiac mortality risk in asymptomatic applicants for life insurance should include both traditional risk factor assessments in combination with age and gender specific percentiles for coronary calcium. New data from both new and ongoing clinical trials will seek to further support the predictive value of coronary calcium scores as an independent and incremental predictor of hard cardiac events. 相似文献

We call markets in which intermediaries sell networks of suppliers to consumers who are uncertain about their needs "option demand markets." In these markets, suppliers may grant the intermediaries discounts in order to be admitted to their networks. We derive a measure of each supplier's market power within the network; the measure is based on the additional ex ante expected utility consumers obtain from the supplier's inclusion. We empirically validate the WTP measure by considering managed care purchases of hospital services in the San Diego market. Finally, we present three applications, including an analysis of hospital mergers in San Diego. 相似文献

As health reform is deconstructed, we need to stop and do some deconstructing of our thinking about it, looking at the context of our assumptions or frames. If we think of health as taking the supreme welfare of the people seriously, we will not allow it to be framed only in terms of for-profit interests and the status quo. Nurses have expertise and knowledge regarding what is needed for a quality health care system. We have to join the conversation with as many good questions as ideas. Working from a different frame, one that reflects more of your values, may give you new insights into holding the conversation. 相似文献
