Case-mix systems for nursing homes use resident characteristics to predict the relative use of resources. Seven systems are compared in structure, accuracy in explaining resource use, group homogeneity, and ability to identify residents receiving heavy care. Resource utilization groups, version II (RUG-II), was almost uniformly the best system, although management minutes and the Minnesota case...

This paper introduces singular mix-valued logical networks and singular mix-valued logical control networks. Via semi-tensor product, a singular mix-valued logical network can be converted to an algebraic form. On this basis, the normalization problem and solvability are discussed. Then, fixed points and cycles of singular mix-valued logical networks are also studied. Furthermore, the optimal c...

This article summarizes the main findings of a study comparing three generic Medicaid nursing home payment systems: case-mix, facility-specific, and class-rate. The major comparative analyses examined patient-level case mix and quality, facility-level costs, Medicaid payment rates, and profitability. The study also analyzed case-mix payment systems in greater detail, emphasizing the earlier sys...

The Japanese medical care system, highly rated internationally, has recently experienced a crisis that has placed a burden on all of its citizens, providers, and payers, due to the expansion of medical expenditures in rapidly aging society with the stagnant economy. To address this, in April 2003, Japan implemented a case-mix payment system, instead of conventional fee-for-service payment, base...

South Carolina Medicaid implemented prospective payment by diagnosis-related group (DRG) for inpatient care. The rate of complications among newborns and deliveries doubled immediately. The case-mix index for newborns increased 66.6 percent, which increased the total Medicaid hospital expenditure 5.5 percent. Outlier payments increased total expenditure further. DRG distribution change among ne...

In this paper, we continue our study of learning the kernel. We present a reformulation of this problem within a feature space environment. This leads us to study regularization in the dual space of all continuous functions on a compact domain with values in a Hilbert space with a mix norm. We also relate this problem in a special case to regularization. 1This work was supported by NSF Grant IT...

There is a real need among researchers and students for pedagogical resources. In France, information retrieval techniques have been developed, for example in the Doc'CISMeF web site. As Pubmed, documents are indexed with (French) MeSH terms, one of the problems discovered, in quality studies, is the inadequacies between the user requests and the MeSH controlled vocabulary. Moreover, French (bu...

BACKGROUND There will be increasing pressure to publicly report and rank the performance of healthcare systems on human immunodeficiency virus (HIV) quality measures. To inform discussion of public reporting, we evaluated the influence of case-mix adjustment when ranking individual care systems on the viral control quality measure. METHODS We used data from the Veterans Health Administration ...

Since 2007, all Romanian hospital discharges are validated based on the clinical data sent by hospitals. Consequently, the Ministry of Health developed a set of indicators, in order to evaluate the hospital management performance. This evaluation was first done in 2008, based on the new legal regulations that introduced Hospital Management Contracts between hospital managers and Ministry of Hea...
