The Economic Evaluation of Medical Devices

Andreas Kirisits, W. Ken Redekop

The economic evaluation of medical technology has evolved as a key element in supporting health budget allocation decisions. Among suppliers of innovation, the medical device industry is one of the most dynamic fields of medical progress with thousands of new products marketed every year. Accordingly, the broad variety of technologies covered by the umbrella term 'medical devices' have come under increasing scrutiny regarding their cost effectiveness. In the process, a number of device-specific factors have become apparent, each of which can complicate a thorough economic evaluation and limit its informative value. Some of these factors relate to specific characteristics of device functioning. Examples of such factors include the fact that most technologies require, or form part of, a procedure and that many devices have multiple indications or purposes. Others in turn reflect external conditions and are more general in character, such as the regulatory framework that a medical device manufacturer faces prior to market approval and the structure of the medical device industry. Drawing on the available literature, these complicating factors and their practical implications are discussed and used as a basis to elaborate on the emerging challenges for the economic evaluation of medical devices.
