Non-use of cochlear implants by post-lingually deafened adults

Area of Science:

• Otolaryngology
• Medical device research
• Health economics

Background:

• Adult cochlear implantation is a complex procedure with potential medical/surgical complications.
• Assessing long-term outcomes, including mortality and device non-use, is crucial for understanding the overall success and cost-effectiveness of cochlear implants.

Purpose of the Study:

• To document medical/surgical complications in post-lingually deafened adults receiving cochlear implants.
• To compare mortality rates with the general population.
• To identify risk factors for elective non-use and analyze the impact on costs.

Main Methods:

• A longitudinal prospective observational study was conducted.
• 313 adult patients receiving cochlear implants across nine UK hospitals were followed.
• Data collected included patient status, duration of use, costs, auditory identification, and self-reported benefit.

Main Results:

• Cumulative mortality (6.3%) was comparable to the general population.
• Major complications occurred in 8.0% of patients, decreasing with experience.
• Low auditory performance and benefit were significant risk factors for elective non-use, increasing costs by 5-10%.

Conclusions:

• Medical/surgical complications were generally well-managed without compromising patient benefit.
• Monitoring patient benefit is essential for early intervention and cost-effectiveness.
• Further follow-up is needed to identify pre-operative risk factors for elective non-use.
