A cross-sectional description of open access publication costs, policies and impact in emergency medicine and critical care journals

Introduction :Finding journal open access information alongside its global impact requires access to multiple databases. We describe a single, searchable database of all emergency medicine and critical care journals that include their open access policies, publication costs, and impact metrics.Methods:A list of emergency medicine and critical care journals (including citation metrics) was created using Scopus (Citescore) and the Web of Science (Impact Factor). Cost of gold/hybrid open access and article process charges (open access fees) were collected from journal websites. Self-archiving policies were collected from the Sherpa/RoMEO database. Relative cost of access in different regions were calculated using the World Bank Purchasing Power Parity index for authors from the United States, Germany, Turkey, China, Brazil, South Africa and Australia.Results:We identified 78 emergency medicine and 82 critical care journals. Median Citescore for emergency medicine was 0.73 (interquartile range, IQR 0.32­1.27). Median impact factor was 1.68 (IQR 1.00­2.39). Median Citescore for critical care was 0.95 (IQR 0.25­2.06). Median impact factor was 2.18 (IQR 1.73­3.50). Mean article process charge for emergency medicine was $2243.04, SD = $1136.16 and for critical care $2201.64, SD = $1174.38. Article process charges were 2.24, 1.75, 2.28 and 1.56 times more expensive for South African, Chinese, Turkish and Brazilian authors respectively than United States authors, but neutral for German and Australian authors (1.02 and 0.81 respectively).

Most Influential Medical Publications of the Last 20 Years (1990-2012): a Collection from Journals with the Highest Impact Factor

As the performance of the clinical medicine relies on evidence-based facts as well as particular landmark researches; this collection of influential medical articles that changed and/or guided most current recommendations used in the daily basis of clinical medicine gives the top spotlight of new trends of management and treatment. The compilation is made from a search into MEDLINE; PubMed; DynaMed; CINAHL; and Academic Search Premier as well as systematically from reference lists of studies and relevant reviews. The inclusion criterion was based on the impact factor of publishing journals that were mostly renowned magazines; which expresses a measurement of the frequency that an article has been cited during a period of time. 478 articles classified according to specialties and sub-specialties were collected from 103 medical journals published approximately in a period of 20 years (1990-2012). In fact; referral materials (Books et Encyclopedias; on-line links; etc) sustained the selecting process that; although we assume exhaustive in the methodology used; but exiguous considered how challengeable and quickly-progressing clinical researches are; gave the most eventful recent researches that had influenced the clinical Medicine. However; opinions expressed within articles compiled are not necessary gold standards or landmarking facts; though they open the perspective on multiple interchangeable evidence-based factors that guide the universal tendency upon the medical management. Thus; regarded how fast medical researches and new facts progress; we recommend checking furthermore on diagnostic and treatment new approaches
