Given the vast scope of clinical activity, evaluating the work undertaken in hospitals is problematic. . The number of possible diagnoses and interventions runs into thousands, and analysis at such a detailed level is not feasible. In recent years, various case mix classifications have been developed, combining treatments and diagnoses into a more manageable number of homogeneous groups. The ai...

Background: In 2012, Switzerland changed from retrospective to prospective hospital payment based on diagnosis related groups (DRGs), following the example of the United States, Australia, and Germany. As in these countries, the objective of this transition was to motivate hospitals to improve efficiency by making them bear financial risk to some extent.Objective:...

We analyze the angular clustering of z ∼ 2.3 distant red galaxies (DRGs) measured by Quadri et al. (2008). We find that, with robust estimates of the measurement errors and realistic halo occupation distribution modeling, the measured clustering can be well fit within standard halo occupation models, in contrast to previous results. However, in order to fit the strong break in w(θ) at θ = 10, n...

Measurement forms the basis for empirical health services research including pharmaceutical practice and policy research. The measurement process is designed to record and capture the underlying construct and concept. In healthcare, critical policy and practice discussions are based on cost, quality, and access. These concepts or constructs have to be measured and analyzed using variables to ev...

During the growth of axons, the surface area of the neuron increases dramatically. Membrane addition as well as exchange could contribute to rapid membrane dynamics or flow. Using diffusing latex beads to monitor membrane flow, we find that axonal membrane flows rapidly (7 microns/min) from growth cone to cell body during axon growth and that flow is inhibited by brefeldin A. To power this flow...

Pharmacy cost data from the University HealthSystem Consortium (UHC) Clinical Database for specific diagnosis-related groups (DRGs) were reviewed to assess their applicability to a university medical center and to identify opportunities to reduce costs. UHC headquarters was contacted by telephone to determine UHC's data collection methods. Pharmacy costs for DRG 302 (kidney transplant) at the U...

Medicare patients in five diagnosis-related groups (DRGs) associated with heavy use of post-hospital care discharged from 52 hospitals in 3 cities were followed up at 6 weeks, 6 months, and 1 year to determine the factors associated with their being discharged home with or without home health care and the correlates of improvement in their functional status. Models correctly predicted those dis...

We analyze the recently released data from the Centers of Medicare and Medicaid Services (CMS), which includes hospitalspecific charges for over 3,000 hospitals across the US for 100 most common inpatient discharges. The goal of this work is to study the variation in the amount that hospitals charge for a given diagnosis-related group (DRG), which is a group of similar diagnoses and clinical pr...
