Cross-subsidies and payment for hospital care   总被引:2,自引:0,他引:2  
This study uses hospital data from the 1979 American Hospital Association Reimbursement Survey in a multivariate framework to assess the impact of discounts and third-party reimbursement on hospital costs and profitability. Three central issues are addressed: (1) Is a differential payment justified for Medicare, Medicaid, and/or Blue Cross on the basis of differential costs? (2) Have the cost-containment efforts of the dominant payers reduced total payments to hospitals? and (3) What part of the overall savings in payments to hospitals is in the form of reduced costs rather than reduced profits? On the basis of the evidence in this study, we find (1) that the differential payment is not justified; (2) that the cost-containment efforts of the dominant payers have reduced total payments to hospitals somewhat, but a substantial amount of cost-shifting remains; and (3) that the savings is in profits, rather than in costs.  相似文献

This article analyses the current knowledge about corruption and its legal consequences among university students. Based on data from 1,511 undergraduate and graduate students from all academic disciplines at four major universities in the German-speaking part of Switzerland, it appears that the majority of students have difficulty identifying corrupt behaviour and its legal consequences. Law students achieve slightly better results. However, even law students demonstrate a significant lack of knowledge of corruption issues. In particular, most of the students are unaware that corruption that occurs abroad can also be prosecuted in Switzerland. The limited knowledge among students regarding corruption and its legal consequences as identified in this study suggests that the teaching and study of anti-corruption-related subjects should be better integrated into the curricula of universities and business schools.  相似文献

This article provides a nationally representative profile of noninstitutionalized children 0 to 17 years of age who were receiving support from the Supplemental Security Income (SSI) program because of a disability. To assess the role of the SSI program in providing assistance to low-income children with disabilities and their families, it is important to obtain detailed information on demographic characteristics, income and assets, health and disabilities, and health care utilization. Yet administrative records of the Social Security Administration do not contain many of the relevant data items, and the records provide only an incomplete picture of the family relationships affecting the lives of children with disabilities. The National Survey of SSI Children and Families fills this gap. This summary article is based on survey interviews conducted between July 2001 and June 2002 and provides some highlights characterizing children with disabilities who were receiving SSI and their families. Most children receiving SSI (hereafter referred to as "SSI children") lived in a family headed by a single mother, and less than one in three lived with both parents. A very high proportion, about half, were living in a household with at least one other individual reported to have had a disability. About 70 percent of children received some kind of special education. SSI support was the most important source of family income, with earnings a close second. On average, SSI payments accounted for nearly half of the income for the children's families, and earnings accounted for almost 40 percent. When all sources of family income were considered, slightly more than half (54 percent) of SSI children lived in families above the poverty threshold, a notable fact given that the federal SSI program guarantees only a subpoverty level of income. However, beyond these averages there was substantial variation, with some children living in families with income well below the poverty threshold and others having income well over 200 percent of the poverty threshold. About one-third of SSI children lived in families owning a home, two-thirds lived with parents or guardians with at least one car, and about 40 percent lived with parents or guardians with zero liquid assets. Less than 4 percent lived with adults who owned stocks, mutual funds, notes, certificates of deposit, or savings bonds. The Social Security Administration's administrative records contain only a limited amount of information about disability diagnoses. The National Survey of SSI Children and Families supplements those records with data from an array of questions on functional limitations, self-reported health, and the perceived severity of disabilities. The data suggest that a great degree of variation in severity exists within the childhood caseload, as reflected in reports of the presence or absence of six functional limitations, perceived overall health status, and perceived impact of disability on the child's ability to do things. Overall, 36 percent of the children were reported to have had disabilities that affected their abilities to do things "a great deal," and for 21 percent their difficulties had very little or no impact. Physical disabilities were most common among children aged 0 to 5, and mental disabilities dominated the picture for the other two age groups: 6 to 12 and 13 to 17. Virtually all SSI children are covered by some form of health insurance, with Medicaid being by far the most common source of health insurance coverage. Just as in the case of the severity of disabilities, substantial variation was reported in health care utilization among SSI children. Almost 30 percent of children had two or fewer doctor visits during the 12 months preceding the interview, and close to 50 percent had five or more doctor visits. About four-fifths of the children had no reported hospitalizations or surgeries during the previous year. More than 40 percent of the children visited an emergency room during the previous year, most of them more than once. Importantly, no out-of-pocket costs associated with medical care were reported for more than two-thirds of the children, and only about 3 percent had annual expenses exceeding $1,000 for physical and mental health care. This finding suggests that SSI payments are not used to cover medical expenses for the overwhelming majority of children. The use of supportive therapies varied widely among SSI children: more than half reported having used physical, occupational, or speech therapy; only 8 percent used respite care for the parents or other family members. An analysis of the perception of the survey respondents shows that more than one-third of children had unmet needs for mental health counseling services, and about three-quarters of families had unmet needs for respite care. In several service categories, the proportion perceived to have had unmet service needs was around 10 percent or less. In the dominant service category of physical, occupational, and speech therapy, only 11 percent perceived to have had unmet service needs.  相似文献
