![]() And as those journals grew in visibility and reputation, we embarked on a second phase of expansion into further specialties: Child and Adolescent Health, Diabetes and Endocrinology, Digital Health, Gastroenterology and Hepatology, Global Health, Haematology, Healthy Longevity, HIV, Microbe, Planetary Health, Psychiatry, Public Health, Respiratory Medicine, and Rheumatology. ![]() We launched three offspring in quick succession - The Lancet Oncology, The Lancet Infectious Diseases, and The Lancet Neurology. When I became Editor-in-Chief of The Lancet in 1995, my hope was to expand the idea of The Lancet beyond a single journal. I would like to dedicate The Lancet Group’s success this year to John and his contribution over the past 30 years. His journal played a crucial part in publishing science underpinning our understanding of COVID-19. The Editor-in-Chief of The Lancet Infectious Diseases, John McConnell, very sadly died unexpectedly earlier this year. And The Lancet Infectious Diseases from 25.1 to 71.4. The Lancet Public Health from 21.6 to 72.4. The Lancet Psychiatry rose from 26.5 to 77.1. The Lancet Microbe posted a first Impact Factor of 86.2. The Lancet Respiratory Medicine rose from 30.7 to 102.6. All Lancet journals listed with the JCR saw their Impact Factors rise . The Lancet Group is a collection of 24 titles. But for the first time in the controversial era of the Impact Factor, The Lancet can now fairly claim to be the world’s leading medical journal. The NEJM also saw its Impact Factor rise impressively to 176, with The Journal of the American Medical Association (JAMA) close behind on 157. But in an era of pandemic science, The Lancet saw its Impact Factor rise from 79 in 2020 to 202 in 2021. The NEJM has reigned supreme since Impact Factors were first introduced in 1975. ![]() So it was an historic moment for The Lancet when this year we displaced The New England Journal of Medicine (NEJM) to reach the first position in the JCR’s General and Internal Medicine category. Yet, like it or not, this number matters. Editors tack between attachment and animosity to the number their journal is assigned in Clarivate’s Journal Citation Report (JCR). Careers can be made by publication in the top cited journals. We know that some country’s scientific institutions, even governments, follow the undulations of the Impact Factor with astonishing care and attention. And we may dislike the game-playing we know some editors indulge in: varying numbers of citable items published in order to optimise the Impact Factor calculation.īut we also live in the real world of competitive science. ![]() We might resist the idea of constructing football-like league tables for scientific journals. Editors have a love-hate relationship with the Impact Factor. ![]()
