The Cost of Cochlear Implantation : A Review of Methodological Considerations

Abstract EN

Objectives.

Cost studies can provide useful guidance, so long as they adhere to accepted methodology.

Cochlear implants (CIs) are electronic devices introduced surgically into the inner ear.

It is a relevant example to review cost study analyses because of its costliness.

The aim of this study was to review relevant published cost studies of CI to analyze the method used.

Methods.

First, we described the key points of cost study methodology.

Cost studies relating to CI were systematically reviewed, focussing on an analysis of the different methods used.

Results.

The methods, data sources, and estimated cost categories in each study varied widely.

The paper showed that cost studies adopted significantly different approaches to estimate costs of CI, reflecting a lack of consensus on the methodology of cost studies.

Conclusion.

To increase its credibility, closer agreement among researchers on the methodological principles of cost studies would be desirable.
