Abstract

Introduction

Intensive care units (ICUs) are the most frequent setting for serious medical errors, which not only have serious health consequences but also an economic impact. In this article, using a theoretical model, we evaluate four medication administration systems: conventional preparation by nursing staff, MINIBAG Plus delivery system, compounding center preparation, and premix drugs.

Methods

We designed a decision tree model from a third-party payer perspective, and the time horizon of the acute event. Local costs, in Colombian pesos (US $1 = 1784 COP$), were obtained from tariff manuals, medication costs from Sismed information system, and clinical variables from the published literature, and uncertainty was dealt with by an expert panel. The drug used for the model was dopamine.

Results

Average costs for each dopamine dose delivered were $46,995 for premix, $47,625 for compounding center, $101,934 for MINIBAG Plus, and $108,870 for drug prepared in the ICU. The variability of these results is higher for compounding center than for premix, and even higher for MINIBAG Plus and nurse delivery.

Conclusions

The use of premix drugs can be a cost-saving strategy, which decreases medical errors in drug administration in the ICU, particularly if it is part of an integral error reduction program.
