Comparative usefulness of MEDLINE searches performed by a drug information pharmacist and by medical librarians.

The usefulness of MEDLINE searches conducted by a drug information pharmacist who had received online training was compared with the usefulness of searches conducted by medical librarians. Searches for literature pertinent to select drug information requests received at a university drug consultation service during a three-month period were conducted independently by the pharmacist and one of three reference librarians. The three librarians had received extensive online search training and were experienced in conducting MEDLINE searches; the pharmacist was trained by a fourth experienced librarian-searcher using National Library of Medicine (NLM) training materials. For each drug information request, the pharmacist and the librarian searched two MEDLINE files on the NLM service. The printouts generated by the two searchers were evaluated by two drug information pharmacists in terms of how useful each list of citations would be in enabling the drug information pharmacists to answer the related question. The majority of printouts in 48 sets of searches were judged to be useful. Of the 96 possible "best search" votes (two votes for each of the 48 sets of printouts), the pharmacist's searches received 34 votes, the librarians' searches received 28 votes, and there were 34 tie votes. The numbers of useful primary and alternate citations were found to be the best predictors of whether a given printout would receive the "best search" rating. MEDLINE searches performed by a drug information pharmacist with online training, in response to drug information requests, were judged by drug information pharmacists to be as useful as searches performed by librarians.
