Impact of Expanding Eligibility Criteria for Cochlear Implantation – Dynamic Modeling Study

alexandrossfakianakis shared this article with you from Inoreader Impact of Expanding Eligibility Criteria for Cochlear Implantation – Dynamic Modeling Study via The Laryngoscope The aim of this study was to explore the impact of further expanding unilateral CI criteria in those with severe hearing loss (HL) (61–80 dBHL) in terms of number of CI recipients, costs, quality of life, and cost-effectiveness. Based on its outcomes, the described expansion appears to constitute a cost-effective use of healthcare resources. However, it would require a significant increase in diagnostic, operative and rehabilitative capacity. These quantitative estimates can serve as a basis for wider societal deliberation on the question wheter such an increase can and should be pursued. Objectives Eligibility criteria for cochlear implantation (CI) are shifting due to technological and surgical improvements. The aim of this study was to explore the impact of further expanding unilateral CI criteria in those with severe hearing loss (HL) (61–80 dBHL) in terms of number of CI recipients, costs, quality of life, and cost-effectiveness. Methods A dynamic population-based Markov model was constructed mimicking the Dutch population in three age categories over a period of 20 years. Health states included severe HL (61–80 dBHL), profound HL (>81 dBHL), CI recipients, and no-CI recipients. Model parameters were based on published literature, (national) databases, expert opinion, and model calibration. Results If persons with severe HL would qualify and opt for CI similar to those with profound HL now, this would lead to a 6–7 times increase of new CI recipients and an associated increase in costs (€550 million) and QALYs (54.000) over a 20-year period (incremental cost utility ratio: 10.771 euros/QALY [2.5–97.5 percentiles: 1.252–23.171]). One-way-sensitivity analysis indicated that model outcomes were most sensitive to regaining employment, utility associated with having a CI, and costs of surgery and testing. Conclusion Our findings suggest that expanding eligibility for CI to persons with severe HL could be a cost-effective use of resources. Clearly, however, it would require a significant increase in diagnostic, operative, and rehabilitative capacity. Our quantitative estimates can serve as a basis for a wider societal deliberation on the question whether such an increase can and should be pursued.
