Abstract

Many articles were recently published in the British Medical Journal concerning information in the clinical practice; they also discussed the application of the Shaughnessy's formula on evaluating different kinds of informations retrieved. Objectives. To test the the capability of the formula to evaluate and rate each response given in a medical information service. Methods. The factors of the formula (Utility = Relevance x Validity / Work) were rated according to a 5 point scale, obtaining results ranging between 0.20 to 25. Then the implementation of the formula was tested on a sequential sample of 80 requests of drug information received by the DOCTORline service in July-August 1997. Results. Mean values of relevance, validity and work were respectively 3.1 (±0.8), 3.2 (±1.3) and 3.2 (±1.5). No correlation was found between the factors (relevance vs. validity r=0.10; relevance vs. work r=0.03; validity vs. work r=0.08). Mean value of the answers given to the 80 questions was 4.8 (±5) and their distribution seemed bimodal. Conclusions. We discuss how monitoring and controlling the quality of an information system for the physicians can benefit from the applications of this formula, and the problems related to the low number of answers we analized and the difficulty in standardizing the values to be given to the factors.
