The 28-percent change in average Medicare inpatient cost per case between 1984 and 1987 is decomposed into three components: input price inflation, changes in average cost within diagnosis-related groups (DRGs) (intensity), and changes in the distribution of cases across DRGs (case mix). We estimate the contributions of technology diffusion and outpatient shifts to within-DRG and across-DRG cos...

This research focuses upon the relationship between a child's age and the likelihood that the child was treated at a Specialist Children's Hospital rather than at a local hospital. While it is generally regarded that younger patients are more resource intensive, a study was required to determine whether the Specialist Children's Hospitals attracted younger patients. The analysis is based on 42,...

The costing of hospital outputs, and especially of acute admitted patients categorised by DRG, has been the focus of considerable attention in the last decade. Many individual hospitals now routinely estimate the costs of their main products, several State and Territory health authorities undertake periodic multi-site studies, and there have been a few one-off national studies. This paper summa...

Germany will begin a change to per case payment by DRG from January 2003. It has selected the Australian DRG classification as the basis for patient categorisation, in preference to the many other DRG variants around the world. The main aim is increase control over expenditure. We describe some of the reasons for high levels of spending on hospital inpatient care, including the fragmented insur...

The diagnosis related groups (DRG) classification was designed primarily to categorize patients of acute short-stay hospitals in urban areas. As one might expect, many studies have shown it is a less effective predictor of the needs--and consequently the costs of care--of remote and socio-economically disadvantaged communities. One way of improving the equity of funding involves separating the ...

The diagnosis-related groups (DRG's) have classically focused on resources consumed during a hospital stay. DRG's can also be considered categories for describing cases admitted to a hospital. In this article, we illustrate how consistent patterns of variations in admission rates can be used to classify DRG categories according to the Index of Discretionary Admissions. The consistency of variat...

INTRODUCTION Casemix reimbursement was introduced to Singapore in October 1999 using the Australian National Diagnosis Related Groups Version 3.1 (AN-DRGs 3.1). The possible impact of this classification system on a Singapore Children's Hospital is discussed. MATERIALS AND METHODS Data on paediatric patients in KK Women's and Children's Hospital (KKH) were drawn from the inhouse Datamart ware...

In October 1998, the definition of a transfer in Medicare's hospital prospective payment system was expanded to include several post-acute care (PAC) providers in 10 high-volume PAC diagnosis-related groups (DRGs). In this methodological article, the authors respond to a congressional mandate to consider more DRGs in the definition. Empirical results support expansion to many more DRGs that are...

Medicare's use of diagnosis-related groups (DRGs) and the resource-based relative value scale (RBRVS) has led to interest in developing a national all-payer system in which insurers use the same payment methods and payment rates. Using data for 81 high-volume DRGs from 457 California hospitals, we conclude that a single set of rates for hospital care would not be appropriate. On average, Medica...
