Adverse drug effects: evaluation of four secondary reference sources

Four adverse drug effect abstracting services, Adverse Drug Reaction Index, Clin-Alert, Current Drug Experience Literature, and Reactions were evaluated. Each service was evaluated in terms of the total number of articles cited, cost per citation, lag time, and time requirements for searches. The Adverse Drug Reaction Index was found to retrieve the most total and unique citations. Its potential disadvantages included the longest lag time and a high overall cost for the system. Reactions provided an alternative to this service, although it provided fewer total and unique citations. However, its overall costs is less, and the lag time is shorter. Clin-Alert ad Current Drug Experience Literature provided significantly fewer citations than the other services. Both services did retrieve unique citations.     

JAT's impact factor--room for improvement? Journal of Analytical Toxicology

The impact factor of a scientific journal is simply the ratio of the number of citations to the number of citable items (articles and reviews) over a given time period, usually two years after the year of publication. Trends in the impact factor of Journal of Analytical Toxicology (JAT) are reviewed and compared with other leading journals in the forensic sciences and toxicology. In particular, the journals that frequently cite JAT articles (citing journals) and the journals cited in articles published in JAT (cited journals) are compared and contrasted. The reasons for citing a particular article are considered, and some suggestions are made for improving the impact factor of JAT, if this is deemed necessary. This could be achieved in a number of ways, such as speeding the editorial-handling and peer-review processes, by including one or more invited review articles in each issue of the journal, or by increasing the number of references cited so the references/article ratio increases. Regardless of journal impact factor, an article should be judged by its usefulness to the field and not the prestige of the journal where it is published.     

Citation analysis of 541 articles published in drug and alcohol journals: 1984-1988.

Citation histories of 541 articles published in 1984 in 12 drug and alcohol journals were followed through 1988. Considerable variability in mean citation rates across journals was observed. The mean citation rate for the 541 articles was 3.48. Approximately 71% of the articles examined were cited at least once between 1984 and 1988. The present findings suggest that articles published in drug and alcohol journals may be cited more frequently, and exert their influence longer, than those of the social science literature generally. Qualitative analyses suggest that methodological and review articles tend to be cited most frequently. The need for a comprehensive scientometric examination of the drug and alcohol literature is emphasized as is the potential role of multivariate techniques in the identification of variables predictive of individual article and journal citation rates.     

Impact of JAT publications 1981-2003: the most prolific authors and the most highly cited articles

The Journal of Analytical Toxicology (JAT) recently celebrated its 25th anniversary as an international periodical devoted to publishing scholarly articles in the field of analytical and forensic toxicology. Over the years many important papers spanning the entire field of chemical toxicology have appeared in JAT. One way to assess the usefulness of these papers is by looking at the number of times they subsequently become cited in the reference lists of papers published in other peer-reviewed journals including JAT itself (self-citations). The Thomson Institute for Scientific Information (ISI), headquartered in Philadelphia, PA, has produced a citation database containing all JAT articles published between 1981 through 2003 (N = 2254). This database was used to gather information about the most prolific authors of articles appearing in JAT, the most highly cited articles, the inter-relationships between co-authors, and the countries where the work originated. The person listed most frequently as an author was E.J. Cone, who authored or co-authored 69 papers that attracted a total of 1432 citations, giving a citation impact of 20.76. However, the most highly cited article in JAT was a solo-author work from 1981 by M.E. Jolley describing a fluorescence polarization immunoassay for the analysis of therapeutic drugs in plasma, which was cited 184 times. Working and writing in teams can boost the output of scientific articles as exemplified by the Institut de Médecine Légale in Strasbourg with P. Kintz as the driving force. Kintz and his associates produced the most collaborative work published in JAT. Citation analysis is being increasingly used to evaluate the importance of scientific articles and the journals where these works are published (e.g., impact factors). This article has identified JAT's scientific elite as evidenced by the most prolific authors and the most highly cited papers.
