RT Journal A1 Hersh W T1 ELectronic information retrieval by physicians and medical librarians—reply JF JAMA JO JAMA YR 1999 FD April 14 VO 281 IS 14 SP 1272 OP 1273 DO 10-1001/pubs.JAMA-ISSN-0098-7484-281-14-jac90002 UL http://dx.doi.org/10-1001/pubs.JAMA-ISSN-0098-7484-281-14-jac90002 AB In keeping with an evidence-based perspective, however, I must clarify some of Ms Killoran's points. She is correct that the source of end-user training was not clearly stated in our article. This is because most of the studies included in the systematic review did not indicate who did the training. In the study of searching performance cited in the review that came from my institution,1 training in searching was not done by librarians, but rather by a medical informatics specialist with strong training in information retrieval and other pertinent areas. Killoran's assertion that "end users who train other end users lack the professional expertise necessary to assume the role of quality end-user trainers" is not backed by any studies I am aware of, even though it is probably true in most instances.
