Cost of discarded medication in Indiana long-term care facilities

The cost of discarded medication was studied in 17 Indiana intermediate-care and skilled-nursing facilities with varying bed capacities and drug-distribution systems. During visits to each facility, one or two pharmacists collected data on patients' drug regimens and the quantities of medication dispensed and discarded over periods of one to seven months. A total of $ 5,620 worth of medication ($ 4,472 excluding topical medications) was destroyed in the facilities during the study period. The projected annual cost of discarded medication was approximately $ 15,800 ($ 12,460 excluding topical medications). In the 13 facilities using some type of unit dose drug distribution system, the mean projected annual cost of discarded medication per patient ($ 4.07) was significantly less than for the four facilities using traditional drug-distribution systems ($ 23.54). There was an inverse relationship between bed capacity and mean projected annual cost of discarded medication per patient. The use of unit dose drug distribution systems in all long-term care facilities would be expected to result in substantial savings in the costs of discarded medications.
