Purpose: The Emergency Department (ED) is the front line for providing medical services to diverse patient populations. Timely access to medications is critical to efficient and effective patient care. The use of automated dispensing cabinets (ADCs) is increasingly common. However, inventory management continues to be a major challenge. In an era where financial solvency is vital to the survival of hospitals, pharmacies are tasked with the important goal of achieving cost savings while ensuring operation efficiency. The purpose of this study was to evaluate the impact of interventions aimed to optimize inventory control of ADCs in the ED.
Methods: This is an 8-month retrospective descriptive study of all medication dispenses made from five ADCs in the ED from October 2018 to May 2019. The interventions used by the pharmacy team include: a) monthly adjustment of inventory for drugs stocked in the ADC based on data from computerized physician order entry (CPOE) system and the ADC console, b) biweekly review and resolution of inventory discrepancies generated by end-users, c) monthly review of inventory stock out rates via reports from the ADC console, d) turning on an ADC feature which required end-users to count all medications upon dispense. The primary outcome of the study is cost of inventory stocked in the ADC. The secondary outcomes of the study include stock out rate, discrepancy rate, and the percentage of medications dispensed from the ADCs. Descriptive statistics was used to determine the outcomes in the study.
Results: A total of 147,112 medication dispenses were included for evaluation. The median for the number of medications dispensed per month was 23,531 (22,557-24941). Over an 8 month period, the median (IQR) reduction in cost of inventory stocked in the five machines was $10,981 (10495.28-12362.30). The median stock out rate was 1.03 (0.84-1.42), while the rate of user-generated discrepancy of inventory was 4.15 (3.79-4.57). The median vend:fill ratio was 6.4 (5.4-7.1).
Conclusion: Targeted interventions resulted in cost savings, operational efficiency, and optimized inventory control for ADCs stationed in the ED.
