Revising diagnosis-related groups for neonates

Pediatrics

Abstract

Groups of neonates who are usually treated at hospitals that provide specialized pediatric care are not adequately classified by the use of diagnosis-related groups (DRGs). Therefore, a set of revised DRGs, pediatric modified DRGs (PM-DRGs), have been developed. Use of PM-DRGs substantially improves the classification of neonates in the following ways: a single pediatric modified major diagnostic category has been defined to include only and all neonates (patients younger than 29 days of age when admitted to the hospital); deaths and transfers of newborns are no longer combined into a single group; birth weight (rather than diagnosis) is used as the primary variable to differentiate categories of neonates; and duration of mechanical ventilation, presence of major problems, and surgery are used to define specific PM-DRGs. A total of 46 PM-DRGs have been developed to replace the 7 DRGs for neonates. Based on a sample of discharged patients from 13 children's hospitals, the overall variance reduction in duration of stay for neonates using PM-DRGs was 38.7% compared with 20.4% for DRGs. Variance reduction for PM-DRGs was 45.9% compared with 16.3% for DRGs when operating cost per case was used instead of duration of stay. After remo...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
