Methods: This study is a retrospective cross-sectional study. Data on all patients’ medicine use items between January 1st, 2018 – December 31st, 2022 which obtained from the hospital information system will be analyzed according to category based on the principles of ABC analysis, VEN, and the ABC-VEN combination and a statistical t-test analysis in SPSS to find out differences in medicine use at the Universitas Airlangga Hospital in the pre-pandemic era of COVID-19 versus the era of the COVID-19 pandemic. Results: Based on the results of the study, a total of 6893 drug items were obtained. There was a significant shift in the pattern of non-essential medicines use prescribed to patients after the COVID-19 pandemic (p < 0,05).
