The Cost Effectiveness of Upgrading Cochlear Implant Sound Processors in Australia: A Novel Application of Individual-Level Microsimulation Models

Puntos clave

The research aims to determine when upgrading cochlear implant sound processors becomes cost effective and demonstrates the utility of microsimulation models.
Estimated cost effectiveness of sound processor upgrades considering replacement or repair scenarios.
Utilized microsimulation models to track individual ears in assessing hearing interventions.
Explored the potential application of models to other neuroprosthetic conditions.
Identified specific frequencies at which upgrades are deemed cost effective.
Highlighted the value of microsimulation in evaluating individual-level interventions for hearing loss.
Indicated a need for further research on similar approaches for other neuroprosthetic devices.

Resumen

This study estimated the frequencies at which upgrading sound processors may be considered cost effective, assuming that sound processors were eventually beyond replacement or repair. This study also demonstrated the value of microsimulation models in tracking not only individuals, but each ear when assessing the cost effectiveness of hearing interventions. Further research is needed to explore this approach in other conditions and interventions, such as other neuroprosthetics.
