Several authors have suggested that diagnosis-related groups (DRG's) make inadequate allowance for the severity of illness. Before modifications of DRG's are developed, the sources of within-group variation must be precisely defined; not all variation is attributable to the severity of illness. The limitations of the Uniform Hospital Discharge Data Set (UHDDS), of the International Classificati...

• However, newly launched expensive drugs receive specific funding in two countries. In the UK, ‘innovation payments’ can be requested for new treatments. These payments are limited to a period of up to three years. Subsequently, drugs are either reimbursed via the DRG system or added to the high cost drug exclusion list. In Germany, hospitals can request NUBs (Neue Untersuchungsund Behandlungs...

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.from 2008 to 2012, 20740 patients with cirrhosis or duodenal ulcer disease were chosen as sample. using multiple linear regression ana...

a group $g$ is called metahamiltonian if all its non-abelian subgroups are normal‎. ‎the aim of this paper is to provide an updated survey of research concerning certain classes of generalized metahamiltonian groups‎, ‎in various contexts‎, ‎and to prove some new results‎. ‎some open problems are listed‎.

BACKGROUND This study aimed to evaluate the impact of diagnosis-related group (DRG) payments on health-care providers' behavior and the potential best course of action to make a profit under a DRG payment mechanism. METHODS This is a natural experiment study with a tertiary hospital-based dataset. Under a consecutive three-period (3 years) or 12-period (12 seasons) design, length of stay, med...

This paper addresses the impact of payment systems on the rate of technology adoption. We present a model where technological shift is driven by demand uncertainty, increased patients’ benefit, financial variables, and the reimbursement system to providers. Two payment systems are studied: cost reimbursement and (two variants of) DRG. According to the system considered, adoption occurs either w...

OBJECTIVE On October 1, 2013, the reporting of diagnoses and procedures in the U.S. will transition from the clinical modification of the ninth revision of the International Classification of Diseases (ICD-9-CM) to the tenth revision (ICD-10). We estimate the impact of conversion to ICD-10 on Medicare MS-DRG payments to hospitals using 2009 Medicare data. METHODS Using the ICD-9-CM MS-DRG ...

Many hospitals in the 1990s many hospitals were accused of "upcoding" patient diagnostic related groups (DRGs) to increase Medicare reimbursements. We find that between 1989 and 1996, the percentage point share of the most generous DRG for pneumonia and respiratory infections rose by 10 points among not-for-profit hospitals, 23 points among for-profit hospitals, and 37 points in hospitals conve...

The study described in this article sought to develop AN-DRG Version 3 classification revisions for organ transplantation through statistical analyses of recommendations formulated by the Australian Casemix Clinical Committee. Two separate analyses of variance were undertaken for AN-DRG Version 2 and for the proposed Version 3 AN-DRGs, using average length of stay as the dependent variable. The...
