Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jep12363-sec-0001" sec-type="section"> <title>Rationale, aims and objectives</title> <p>To evaluate the performance of several pharmacists in the same department who analysed the same prescriptions in a simulation study.</p> </sec> <sec id="jep12363-sec-0002" sec-type="section"> <title>Methods</title> <p>One hundred prescriptions were retrospectively extracted from the prospective database of our hospital. Five clinical pharmacists working in the same department were asked to analyse individually the order lines of each prescription as if it were part of their routine daily practice. Afterward, an independent committee of five other clinical pharmacists reviewed the same 100 prescriptions. We calculated the sensitivity and the specificity of error detection in a line order by using the results of the committee as the gold standard.</p> </sec> <sec id="jep12363-sec-0003" sec-type="section"> <title>Results</title> <p>A total of 908 order lines were analysed (mean 9 ± 3 order lines per prescription). Fifty‐one medication errors were identified by the committee (5.6%), including 23 related to laboratory test results: renal failure, or therapeutic concentrations being too low or too high. The sensitivity of the five pharmacists ranged between 19.6% and 56.9% and the specificity between 92.8% and 98.7%. The rates of agreement between each pharmacist and the committee, assessed using kappa coefficient, were between 0.20 and 0.39. The main factors affecting sensitivity and/or specificity in univariate analysis were the number of drugs per prescription, type of drug prescribed (ATC classification) and the glomerular filtration rate.</p> </sec> <sec id="jep12363-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Discrepancies between the performances of pharmacists exist, as there are between other health care professionals. Pharmacist training, standardization of the pharmaceutical analysis of drug prescription, and implementation of a clinical decision support system allowing biological values to be linked to drug prescriptions could improve individual performance.</p> </sec> </abstract>
