In 1988, an ambitious and extensive project was undertaken in New Jersey to evaluate severity class adjustment of the all-payer prospective payment system. Another project objective was to evaluate alternative strategies for refining diagnosis-related groups (DRGs). The evaluation presented here includes a comparison of DRG refinement using Computerized Severity Index classes and Yale Universit...

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...

OBJECTIVE With the success of DRGs (Diagnosis Related Groups) in developing countries, this prospective payment system has been imported into China from the early 21(st) century. However, DRGs has been struggling and has made little progress since (its adoption in) 2004. This study contributes to the debate on how to bridge the pay-for-service (system/scheme) and DRGs (Diagnosis Related Groups)...

AIMS As part of the diagnosis related groups in Europe (EuroDRG) project, researchers from 11 countries (i.e. Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Spain, and Sweden) compared how their DRG systems deal with patients admitted to hospital for acute myocardial infarction (AMI). The study aims to assist cardiologists and national authorities to optimize...

The selection of cohorts from national and state databases in Australia usually relies on patient diagnoses according to International Classification of Disease (ICD) codes and/or Diagnosis Related Groups (DRGs). The aim of this study was to select a specific cohort consisting of stroke and transient ischaemic attack (TIA) episodes, thereby allowing the researcher to examine current process of ...

Introduction There has been much evidence provided on the appropriateness of Diagnosis Related Groups (DRGs) as a useful tool for funding, and/or a reimbursement mechanism. DRGs have also proven valuable for management and review of utilization, as well as in conducting research into health systems. Many people believe that DRG–based funding (and performance) holds hospitals accountable for cos...

BACKGROUND AND PURPOSE Accurate data on the distribution of stroke subtypes are essential for understanding the forces driving recent morbidity and mortality trends. The introduction of diagnosis-related groups (DRGs) in the 1980s may have affected the distribution of stroke subtypes as defined by International Classification of Diseases, Ninth Revision (ICD-9), discharge diagnosis codes. MET...

Introduction The DRG system is based on the list of MDCs (Main Diagnosis Categories) defined on the basis of the principal diagnosis. At the same time, the surgical procedure is typically accepted in one or more MDCs. Thus, the cases with the same procedure code can be assigned to different DRGs depending on the principal diagnoses. In the NordDRG system, some DRGs (error DRGs) are reserved for...

Preface The increase in the cost of hospital care has been a persistent and growing problem for both the Medicare program and the general public for more than iS years. A substantial portion of the increase in hospital costs has been attributed to an increase in the use of new and existing medical technologies. Congress recently legislated a new prospective per-case payment system for the Medic...
