ABC-VEN analysis of drug use in outpatients at a neurology department in Indonesia

Background: Drug inventory in hospitals must be maintained appropriately and effectively to promote affordability and sustainable drug availability.     Objective: To analyse the drug use profile in the neurology department with ABC-VEN.     Method: A retrospective observational study was conducted with prescription samples of outpatient drugs in the Neurology Department at Airlangga University Hospital, Indonesia, from January to March 2020. An analysis of ABC-VEN was performed.     Results: From 1,993 prescription samples, the total types of drugs used were 131. The ABC analysis based on the drug use value and investment value found that 16 vs. 6, 16 vs. 10, and 99 vs. 115 types of drugs belonged to the A, B, and C categories, respectively. VEN analysis showed that Group V had 16 types of drugs, Group E had 69 types of drugs, and Group N had 46 types of drugs. ABC-VEN analysis showed that Category I contained 18 types of drugs, Category II contained 68 types of drugs, and Category III contained 45 types of drugs.      Conclusion: There was a discrepancy between the results of the ABC analysis based on the value of drug use, investment value, and the VEN. Using the ABC-VEN analysis helps improve pharmacy management.
