This is a review for Vermeulen’s Cost-effectiveness of an electronic medicationordering system (CPOE/CDSS) in hospitalized patients. [1]

Introduction

The goal of the study was to investigate the balance between the effects and costs of CPOE/[CDSS compared to the traditional paper-based medication ordering.

Methods

The economic evaluation was performed alongside a clinical study (interrupted time series design) on the effectiveness of CPOE/CDSS, including a cost minimization and a cost-effectiveness analysis. All costs of both medication ordering systems are based on resources used and time invested. Prices were expressed in Euros (price level 2009). Effectiveness outcomes were medication errors and preventable adverse drug events. Data collection took place of a four-year period – 2004 thru 2008.

Design, population, and setting. The study was designed as an interrupted time series with two periods of measurement: a pre implementation measurement, in which the paper-based medication ordering system was evaluated, and a post implementation measurement, in which the CPOE/CDS system was evaluated.

Results

Computerized physician order entry is cost-effective over paper prescriptions. The additional costs to prevent one medication error are very small. The additional costs to prevent one adverse drug event are higher, but are still acceptable.
