Summary

Patients with two cochlear implant (CI) processors report significant benefits, experiencing less downtime without sound access. Having a second CI processor is highly valued by users, especially for managing device damage.

Area of Science:

  • Audiology
  • Biomedical Engineering
  • Otolaryngology

Background:

  • Cochlear implant (CI) external sound processor hardware is determined by institutional contracts.
  • Limited literature exists on patient preferences and utilization of CI hardware.
  • Understanding CI processor use is crucial given the high prevalence of CI worldwide.

Purpose of the Study:

  • To evaluate the benefits of a second cochlear implant (CI) sound processor.
  • To understand patient utilization patterns of CI sound processors.

Main Methods:

  • A survey was mailed to patients aged 18+ who received CI between 2016-2020.
  • Patients were divided into two groups: those receiving 1 processor (2018 onwards) and 2 processors (pre-2018).
  • Response rate was 38.0% (100/263 surveys returned).

Main Results:

  • Patients with 1 processor experienced significantly more downtime without sound (31.3%) compared to those with 2 processors (5.6%).
  • 24.3% of the 2-processor group utilized their second processor, often due to primary processor damage.
  • 62.9% of the 2-processor group found the second processor very important; these patients had fewer audiology visits for troubleshooting.

Conclusions:

  • Two CI external processors are highly valued by patients and significantly reduce sound access downtime.
  • Patient preferences and utilization patterns for CI processors should inform patient-centric policies.
  • Institutional contracts influencing the number of CI processors provided necessitate understanding these patient factors.
