Abstract
BACKGROUND: A lack of cost-conscious medication use is a major contributor to excessive healthcare expenditures in the inpatient setting. Expensive medicines are often utilized when there are comparable alternatives available at a lower cost. Increasing prescriber awareness of medication cost at the time of ordering may help promote cost-conscious use of medications in the hospital.
OBJECTIVE: To evaluate the impact of cost messaging on the ordering of 9 expensive medications.
DESIGN: Retrospective analysis of an institutional cost-transparency initiative.
SETTING: A 1145-bed, tertiary care, academic medical center.
PARTICIPANTS: Prescribers who ordered medications through the computerized provider order entry system at the Johns Hopkins Hospital.
METHODS: Interrupted time series and segmented regression models were used to examine prescriber ordering before and after implementation of cost messaging for 9 highcost medications.
RESULTS: Following the implementation of cost messaging, no significant changes were observed in the number of orders or ordering trends for intravenous (IV) formulations of eculizumab, calcitonin, levetiracetam, linezolid, mycophenolate, ribavirin, and levothyroxine. An immediate and sustained reduction in medication utilization was seen in 2 drugs that underwent a policy change during our study, IV pantoprazole and oral voriconazole. IV pantoprazole became restricted at our facility due to a national shortage (-985 orders per 10,000 patient days;
