The Healthcare Educational and Research Foundation (HERF) in Minneapolis undertook a two-year research project to study the effects of health maintenance organizations (HMOs) and competition on the hospital industry in Minneapolis/St. Paul. This article summarizes HERF's major findings surrounding three key questions: (1) do the HMOs in Minneapolis/St. Paul use fewer hospital resources relative to conventional payers?; (2) do recent overall community trends in inpatient use suggest evidence of hospital utilization-reducing effects attributable to HMOs?; and (3) given the highly visible competitive process among Minneapolis/St. Paul providers, do hospital cost and revenue data suggest any evidence of cost-containment? The findings (based on data through 1982) indicate that for comparable patients, Twin Cities HMOs appear to use fewer medical care resources per hospitalized patient. There was, however, no clear evidence of community-wide, utilization-reducing effects directly attributable to the "competitive effect" of HMO introduction and development in the market. In addition, there was no empirical evidence that HMOs (which had enrolled 25 percent of the consumer market by 1982), or other large buyers of inpatient services, have selected hospitals on the basis of price as hypothesized by competition advocates.  相似文献

This study investigated the impact of the abolition of the tender years doctrine on custody decisions in divorce cases. This doctrine supported the presumption that the mother is the more suitable parent for young children. In March of 1981, the Supreme Court of the State of Alabama found this doctrine to be unconstitutional. To assess the hypothesis that this ruling had a significant effect on custodyrelated decisions, a sample of court records for divorce cases in an Alabama county was examined as representative of the state on a number of key variables. Overall, no significant differences were found on indicator variables for the comparisons before and after the ruling. There was neither an increase in custody grants to fathers nor an increase in custody requests by fathers.  相似文献
