“Always Better Control” (ABC) and “Vital
Essential Desirable” (VED) are widely used methods for controlling drug
inventories. The purpose of this study is to contribute to the optimal level of
drug storage for the hospital by evaluating the annual amounts spent on drugs
with (ABC) and (VED). By this means, it is aimed to reduce inventory costs to
an optimum level. In this study, drug consumption data of a private hospital
operating in Istanbul for 2016 was used. Based on the annual unit consumption
and the unit costs of 910 medicines, the total annual expenditure for each drug
was calculated and drugs were ranked in increasing order according to this
calculation. Drugs that accounted for 70% of the total drug expenditure were
classified as Category A, 20% were classified as Category B, and 10% were
classified as Category C. The (VED) analysis was conducted with three
pharmacologists and drugs were classified according to their degree of vital
importance as category “Vital (V)”, “Essential (E)” and “Desirable (D)”. Then,
the data were combined with the (ABC-VED) matrix in three separate categories.
According to a ABC analysis, 70.08% of this expenditure consists of 46 drugs
(A), 19.88% of 92 drugs (B) and 10.04% of 772 drugs (C). According to the (VED)
analysis, it has been determined that 265 drugs are in category “V”, 467 drugs
in “E” and 178 drugs in “D”. According to the (ABC-VED) matrix, there are 298
drugs in the first category, 446 drugs in the second category and 163 drugs in
the third category. Consequently, these analyzes will contribute to management
especially in determining the safety stock levels of drugs that constitute a
significant part of the total expenditure.
