Overview

Retrospective cohort study shows baseline performance predicts improvement in speech recognition and quality of life after cochlear implantation, suggesting important candidacy considerations.

Key Points

  • To examine how baseline performance and device use predict improvements in speech recognition and quality of life after cochlear implantation.
  • Retrospective cohort study of 101 adult unilateral cochlear implant recipients from 2019 to 2023.
  • Outcome measures included AzBio sentence recognition and Cochlear Implant Quality of Life scores at 6 or 12 months post-surgery.
  • Analysis of correlations between daily device use and speech recognition improvements.
  • 97 out of 101 patients showed clinically meaningful improvement in at least one domain post-implantation.
  • 44 patients improved in both speech recognition and quality of life; 43 improved in speech recognition only.
  • Greater daily device use was linked to larger speech-recognition gains (r=0.34, P<0.01), but not to quality of life improvements (r=0.12, P=0.24).
