Alternative to the Science Citation Index impact factor as an assessment of emergency medicine's scientific contributions

Annals of Emergency Medicine
D P Barnaby, E J Gallagher

Abstract

The Science Citation Index "impact factor" is the only available quantitative estimate of a journal's scientific contributions. However, the derivation of this factor contains an intrinsic bias that underestimates the impact of emergency medicine journals. We wished to test the hypothesis that use of an alternative criterion standard would provide an improved profile of the scientific contributions of emergency medicine journals relative to those of other specialties. We used an observational, longitudinal, comparative design in which all Index Medicus citations from Advanced Cardiac Life Support (ACLS) publications were aggregated by journal and then stratified by specialty. Proportions and proportionate trends, relative to total citations, were reported by specialty, facilitating comparison of emergency medicine with other disciplines. Among all eight ACLS publications (1974-1994) 4,062 citations met the inclusion criteria. Emergency medicine journals were referenced in 16% of eligible citations (99% confidence interval [CI], 14% to 17%), a figure exceeded only by internal medicine and cardiology journals. Emergency medicine was the only discipline to show a significant proportionate increase in contributions over the 20-year...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.
