An early indicator of drug success: Top Journal Selectivity Index

Abstract

Igor KissinDepartment of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston, MA, USAAbstract: The Top Journal Selectivity Index (TJSI) is a scientometric index reflecting the potential importance of a new drug. It represents the ratio of the number of all types of articles on a particular drug in the top 20 journals relative to the number of articles in all (>5,000) biomedical journals covered by Medline over the 5 years since the drug’s introduction. The TJSI can be an indicator of a drug’s potential for sustained use: a higher score increases the probability of continuing success.Keywords: bibliometrics, ‘me-too’ drugs, pharmaceutical market, scientometrics
