What Can Long-Term Attendance at Programming Appointments Tell Us About Pediatric Cochlear Implant Recipients?

Abstract

This study sought to understand factors linked to long-term engagement with available post-implant "mapping" review services for individuals who received cochlear implants (CI)(s) as children. Demographics, communication outcomes, and appointment attendance records from an unselected group of 400 participants who received CI(s) between 1985 and 2009 were analyzed. After 5 years post-implant, 85.75% (n = 343) of participants attended the clinic for "mapping" appointments between March 2011 and March 2014, but 14.25% (n = 57) had not attended "mapping" for more than 3 years before March 2014. Findings showed that participants who did attend routine follow-up "mapping" appointments received their first implants at a significantly younger age (mean, 3.73 yr; standard deviation [SD], 3.39) and demonstrated better receptive language performance (mean standard score, 72; SD, 21.2) and better speech perception scores (mean open-set words, 54.1%; SD, 24.4; phonemes, 77.5%; SD, 15.8) suggesting they derived greater benefit from the technology than participants who did not attend (mean age at implant, 6.38 yr; SD, 4.85; mean receptive language standard score, 58.6; SD, 25.6; mean open-set-words, 34.5%; SD, 24.5; phonemes, 62.7.4%; SD, 23.4). The present study identified a profile of pediatric CI recipients who continue to attend follow-up review appointments after 5 years of device experience. Individuals who were non-attenders tended to include part-time and non-users of the technology. This could be due to a range of factors including the use of past speech processor technology (at first 12 months after switch-on), less overall benefit, and the presence of additional special needs.
