Healthcare publisher Lippincott Williams & Wilkins, part of Wolters Kluwer Health, has announced major increases in journal impact factors across its portfolio. According to the 2008 Journal Citation Reports (JCR), published by Thomson Reuters, over 64 percent of 153 ranked LWW journals increased their impact factor. Impact factor is a measurement of the frequency with which peer-reviewed journals are cited by other researchers.
Notable showings include the journal Circulation, which increased its impact factor 14 percent to 14.595. Circulation continues to hold the top spot in the categories of Peripheral Vascular Disease, Hematology, and Cardiac and Cardiovascular Systems, for both impact factor and total cites. LWW dominates the Peripheral Vascular Disease category, publishing all of the top five-and seven of the top ten-journals including Circulation; Circulation Research; Hypertension; Arteriosclerosis, Thrombosis, and Vascular Biology; Current Opinion in Lipidology; Stroke; and Journal of Hypertension. Anesthesiology and Critical Care Medicine are two other subject areas in which LWW leads the pack. LWW claims 5 of the top 10 titles in both these subject areas.
Seven LWW journals achieved JCR ranking for the first time this year, and some garnered high positions on the list. Current Opinion in Ophthalmology entered the rankings at 8th position in Ophthalmology. Journal of Cardiovascular Nursing achieved the 9 spot in Nursing and Pediatric Critical Care Medicine was ranked 10 in Critical Care.
