Do You Know Your H-Index?

Proposed in 2005 by Jorge E. Hirsch, a physicist at the University of California, San Diego, the h-index quantifies scientific output as a single statistic based on both the number and impact of a researcher’s publications.1 An h-index of 40 means that a scientist has published 40 papers that each have at least 40 citations. The h-index conveys the broad impact of work over time and never decreases. It is supposed to be insensitive to the extremes of either non-cited papers or “one-hit wonders.” Authors with similar h-index values are theoretically comparable in overall scientific influence, even if their numbers of papers or citations are very different.

Who’s Using E-books?

The Evidence Behind Point of Care Products

At this year’s annual Medical Library Association conference, we reported on the results of our study which examined the type of evidence used to support content in some commonly used Point of Care (POC) products.  The five POC products included in the study were UpToDate, Clinical Evidence, ACP PIER, DynaMed, and FIRSTConsult.  The references from four topical monographs—hypertension, hyperlipidemia, carbon monoxide poisoning, and asthma—were analyzed in each POC product. The objective was to determine the level of evidence1 of each of the references; for example, a systematic review publication has a higher level of evidence than a practice guideline, which in turn is higher than a case report.
