List of Studies


Patient-reported outcome measures (PROMs) are crucial for understanding the impact of cochlear implants (CIs) on real-world functional abilities and quality of life (QOL) and for monitoring changes over time. However, CI clinical outcome measures traditionally focus solely on CI users' speech recognition ability to evaluate treatment success, which limits our understanding of CI's effects on patients' social isolation, emotional impact, and mental and listening effort related to severe hearing loss. Moreover, patient's speech recognition scores demonstrate low correlations with CI users' real-world communication experiences and QOL. Therefore, there is a critical gap in the measures commonly used to quantify patient outcomes after CI activation. To address this gap, we developed the Cochlear Implant Quality of Life (CIQOL)-35 Profile instrument, which provides a comprehensive, patient-centered assessment of CI-related functional abilities and QOL. However, difficultly in interpreting an individual patient's PROM score is a major barrier for PROM implementation and applications to clinical care. Therefore, additional work is critical for clinicians to appropriately interpret CIQOL-35 Profile scores for individual patients and apply those results to inform intervention decisions and monitor patient progress. In the current study we will longitudinally assess CI users CIQOL scores to help identify CI users with lower functional abilities who may benefit from increased support and allow clinicians to better track functional improvement after implantation for individual patients. This work will inform patient discussions regarding expected outcomes and timeframe for improvement.
