JAMA(the Journal of the American Medical Association),published continuously since in 1883, is an international peer-reviewed general medical journal published 48 times per year. JAMA is the most widely circulated medical journal in the world. JAMA is published in multiple international editions and languages; the online version is made freely available to institutions in developing countries. JAMA's impact factor is 24.8 (the impact factor is a measure of citation rate per article, and is calculated by dividing 1 year's worth of citations to a journal's articles published in the previous 2 years by the number of major articles [eg, research papers, reviews] published by that journal in those 2 years). JAMA's acceptance rate is approximately 8% of the nearly 6000 solicited and unsolicited manuscripts it receives annually; its average time from submission to publication is 115 days and average time from receipt to rejection is 23 days (for additional information, see the JAMA editorial). The Editor-in-Chief of JAMA is Catherine DeAngelis, MD, MPH (see JAMA Editors and Publishers).
