The clinical evaluation of drug information provided by the pharmacists in the intensive care unit

Abstract

Pharmacists working in the intensive care unit (ICU) in Saiseikai Yokohamashi Tobu Hospital are mainly responsible for managing the stock of drugs, providing drug information to other medical staff, educating them for rational drug therapy, and providing pharmaceutical care to the patients. In order to evaluate the contribution to the rational drug therapy, we investigated the acceptance rate of the drug information that the pharmacists in the ICU provided to the physicians from February to May in 2009. The number of cases in which drug information was provided by the pharmacists to the physicians during the period was 288. It was suggested that more than half of the information could optimize the drug dosage regimens and correct the inadequate prescriptions. Furthermore, 98.9% of the information provided by pharmacists was accepted by physicians. We questioned 5 intensivists to evaluate the information with a 5 point scale (maximum score was 4, minimum score was 0) and then the average of score was 3.3. In addition, their evaluation of the information about optimizing the drug dosage regimens marked the highest point (over 3.5). Meanwhile, providing drug information which led the physicians to correct the inadequate prescriptions contributed to reduce the cost of the drug therapy by 900000 yen during the period. As a result, it was suggested that the intensivists highly appreciated the information offered by the pharmacists and the information contributed to enhance high-quality drug therapy. Additionally, the economic impact was identified through the cost reduction in drug therapy. © 2010 The Pharmaceutical Society of Japan.
