Indicators for economic evaluation of drug hospital´'s acquisition

Abstract

Objectives: To propose indicators of evaluation of drug acquisition and to compare their economic results. Methods: The results of the purchase of medications from the Hospital Estadual Américo Brasiliense (HEAB) were evaluated through a descriptive and cross-sectional study. To this end, a documentary survey of drugs purchases and consumption reports was accomplished for a year. The number of medicines purchased in each acquisition, their unit prices, and the monthly consumption rate in units were obtained in order to elaborate the ABC analysis and to calculate the indicators of economic percentage – percentage of savings between the CMED maximum selling price to the government (MSPG) 18% and average unit price of the analyzed acquisitions – and economic ratio – ratio between the CMED (MSPG) 18% and the average unit price of the analyzed acquisi tions. Results: The acquisition efficiency was calculated for 51/72 presentations classified as A and B, according to the ABC curve. The total saving median engendered by the economic percentage was 41,6% (minimum = -2008,6%, maximum = 99,3%, interquartile range (IIQ 25-75%) = -15-54,9) and 0.6 (minimum = 0, maximum = 21.1, IIQ 25-75% = 0.5-1.2) calculated by the economic ratio. Conclusions: It was observed that the acquisition process of HEAB was efficient, since it engendered savings. Because of the similarity of the results obtained by the two indicators, both are considered eligible and applicable to monitoring the economy. However, the economic ratio indicator would be better accepted and implantable by the service due to greater ease of calculation and interpretation than the economic percentage.
