Question

What is ANSI/AAMI CI86 and why is it important in the expansion and transparency of cochlear implant reliability reporting?

Answer

Cochlear is expanding access to reliability information with the introduction of the ANSI/AAMI CI86 Standard, which externally reports on implant and sound processor reliability.1 In accordance with this standard, quality of both implants and processors can be assessed for the first time. 
Historically, quality has largely only been measured as implant reliability and through other subjective assessments. Reliability reporting had previously only been reported based on implant failures following the guidelines outlined by European Consensus Statement, but not all manufacturers maintained full compliance.  

For implants, the new ANSI/AAMI CI86 Standard reporting measurement will be reported as the Cumulative Removal Percentage (CRP).  This expanded reporting mechanism will look at all implants that have been removed for any reason, including infection. The Profile series, with over 90,000 devices implanted, has a CRP of 1.17%, meaning that 98.83% of implants remain functioning in place within 6 years of implantation. 2,3

For the first time, processor reliability is being reported as Failed Component Return Rate (FCRR), which is a percentage calculated by comparing the number of processors returned for repair within a calendar month compared to the cumulative sales of the sound processor over a period of up to 24 months. The Cochlear™ Nucleus® 7 Sound Processor System accounted for 0.3% FCRR within 22 months.2,3

Overall, this new reliability reporting standard allows for transparency and consistency to aid clinicians and their patients in the device decision-making process.

Fostering self-advocacy in elementary-aged students with hearing loss is a complex, multi-parameter endeavor. This course will introduce adaptation of the instructional concepts of coaching and gradual release of responsibility involving the constituents (the student, the family, and the school personnel) and the 3-prong continuum involving the "operator" (the student), the "equipment" (ALDs), and the "listening environment". Specific examples will be provided to optimize the course participants understanding of these concepts.
