Potential medicine waste in the process of outpatients receiving cost-free medicines from medicine pick-up lockers in the North Denmark region.

This study is an initial attempt to investigate potential medicine waste in cost-free medicines dispensed to outpatients via pick-up lockers. Antineoplastic and immunomodulating agents were the most common medicines delivered to medication pick-up lockers in the North Denmark Region from March to October 2023. In this period, approximately 2% of all delivered medicine packages were returned to the hospital pharmacy. Our analysis solely focuses on waste associated with medications left uncollected from medicine pick-up lockers. Addressing the impact of medicine waste in a hospital setting requires a comprehensive approach, thus future studies should also focus on other sites relevant for medication waste as, for example, the patient's household.
