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...

We examined the hypothesis that decreased inhibitory G protein function in diabetic neuropathy is associated with increased protein kinase C (PKC)-dependent phosphorylation of the Goalpha subunit. Streptozotocin-induced diabetic rats were studied between 4 and 8 weeks after onset of diabetes and compared with aged-matched healthy animals as controls. Opioid-mediated inhibition of forskolin-stim...

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...

Several groups have reported apoptosis of dorsal root ganglion (DRG) cells as a prominent feature of diabetic polyneuropathy (DPN), although this has been controversial. Here, we examined subacute (4-month) type 1 diabetic BB/Wor rats with respect to sensory nerve functions, DRG and sural nerve morphometry, pro- and antiapoptotic proteins, and the expression of neurotrophic factors and their re...

We obtained data on hospital length of stay (LOS) and total laboratory charges for Medicare patients admitted to 82 hospitals in Massachusetts during 1994. Five Diagnosis Related Groups (DRGs) were selected: surviving acute myocardial infarction (AMI) with, and without, complications; AMI with death; angina pectoris; and chest pain. The hospitals were grouped according to their laboratory polic...

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...

BACKGROUND Given limited health sources, how to make DRGs (Diagnosis Related Groups) more feasible is a big question in developing countries. This study contributes to the debate on how to bridge the pay-for-service and DRGs during the transitional period of payment reform. METHODS From 2008 to 2012, 20740 patients with cirrhosis or duodenal ulcer disease were chosen as sample. Using multiple...

The excitatory amino acid glutamate plays an important role in the development of neuronal sensitization and the ionotropic N-methyl-d-aspartate receptor (NMDAR) is one of the major receptors involved. The objective of this study was to use a cat model of gastroesophageal reflux disease (GERD) to investigate the expression of the NR1 and NR2A subunits of NMDAR in the vagal and spinal afferent f...

This paper empirically investigates the resource distribution dynamics across Diagnosis Related Groups (DRGs) of elective surgery patients, in a continuing Prospective Payment System (PPS). Existing econometric literature has mainly focussed on the impact of PPS on average Length of Stay (LOS) concluding that the average LOS has declined post PPS. There is little literature on the distribution ...

OBJECTIVE This study evaluated the institutional impact of a substance abuse consultation service in a hospital setting. METHOD Treatment and matched comparison groups were compared on five outcome variables: length of stay, total cost, reimbursement, readmission, and appropriateness of care. The treatment group consisted of patients with discharge diagnoses falling into targeted Diagnostic R...
