AbstractThe authors performed a study to document the impact of a clinical pharmacist on cost saving and cost avoidance in an intensive care unit, and to evaluate the cost saving and avoidance to justify additional clinical pharmacist positions. Over 13 consecutive 5-day weeks, a clinical pharmacist with 50% teaching responsibility documented time spent and all interventions that impacted the cost of drug therapy. Both cost avoidance and cost saving were documented on change in route, change in dosage, change to another drug, discontinuation of therapy, discontinuation of therapeutic duplication, discontinuation of inappropriate therapy, notification of pharmacy of discrepancy, and improper drug-level monitoring avoidance. Cost analysis was calculated based on acquisition costs. The final cost saving was derived from adding cost avoided and cost saved minus pharmacist salary for the time spent in conducting the study. A total of 310 interventions were documented during the 13 weeks (65 days) of the study. The final cost saving was $79,723, which would extrapolate to an annual savings of $318,891. Although 31.3% of interventions involved change of dosage, interventions involving change to another drug (13.9%) had the largest economic impact ($62,527). The majority (85.4%) of the savings involved costs of medications saved (actual dollars saved rather than avoided). The authors concluded that the clinical pharmacist had a significant impact on the cost of drug therapy in the intensive care unit and that the cost of additional clinical pharmacist positions should be justified.
