The open-source Computational Proteomics Analysis System (CPAS) contains an entire data analysis and management pipeline for Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) proteomics, including experiment annotation, protein database searching and sequence management, and mining LC-MS/MS peptide and protein identifications. CPAS architecture and(More)
The Functional Genomics Experiment data model (FuGE) has been developed to facilitate convergence of data standards for high-throughput, comprehensive analyses in biology. FuGE models the components of an experimental activity that are common across different technologies, including protocols, samples and data. FuGE provides a foundation for describing(More)
This paper uses the latest data from the Organization for Economic Cooperation and Development (OECD) to compare the health systems of the thirty member countries in 2000. Total health spending--the distribution of public and private health spending in the OECD countries--is presented and discussed. U.S. public spending as a percentage of GDP (5.8 percent)(More)
Increasing longevity and declining fertility rates are shifting the age distribution of populations in industrialized countries toward older age groups. Some countries will experience this demographic shift before others will. In this DataWatch we compare the effects of population aging on health spending, retirement policies, use of long-term care(More)
Improving care coordination is a national priority and a key focus of health care reforms. However, its measurement and ultimate achievement is challenging. To test whether patients whose providers frequently share patients with one another—what we term ‘care density’—tend to have lower costs of care and likelihood of hospitalization. Cohort study 9,596(More)
Proposals to use episodes of care as a basis for payment and performance measurement are largely conceptual at this stage, with little empirical work or experience in applied settings to guide their design. Based on analyses of Medicare data, we identified key issues that will need to be considered related to defining episodes and determining which provider(More)
This paper presents selected components of the most recent (1999) Organization for Economic Cooperation and Development (OECD) Health Data. Previous trends in spending for health care, supply and use of health care resources, and health status are updated for the thirty industrialized countries in the OECD. In 1999 the United States spent 53 percent more on(More)
U.S. citizens spent $5,267 per capita for health care in 2002--53 percent more than any other country. Two possible reasons for the differential are supply constraints that create waiting lists in other countries and the level of malpractice litigation and defensive medicine in the United States. Services that typically have queues in other countries(More)
Broad-based collaborations are becoming increasingly common among disease researchers. For example, the Global HIV Enterprise has united cross-disciplinary consortia to speed progress towards HIV vaccines through coordinated research across the boundaries of institutions, continents and specialties. New, end-to-end software tools for data and specimen(More)
IMPORTANCE Better continuity of care is expected to improve patient outcomes and reduce health care costs, but patterns of use, costs, and clinical complications associated with the current patterns of care continuity have not been quantified. OBJECTIVE To measure the association between care continuity, costs, and rates of hospitalizations, emergency(More)
