Abstract:
Objective: To investigate the relationship between Cochlear Implant Quality of Life-10 Global (CIQOL-10) and speech
recognition scores 6 and 12 months after cochlear implantation (CI).
Study Design: Retrospective cohort.
Setting: Tertiary referral center.
Patients: 124 patients undergoing CI between 2018-2020 who completed CIQOL-10 questionnaire at 6 and/or 12 months.
Main Outcome Measures: CIQOL-10, CNC and AzBio in quiet and noise scores. Institution benchmark scores for CNC were
38% and 48% at 6 and 12 months, respectively. Institution benchmark scores for AzBio in quiet were 40% and 52% at 6 and 12
months, respectively.
Results: Median CIQOL-10 scores were 31.5 (IQR: 28.8-37.3) at 6 months and 34.0 (IQR: 29.0-37.5) at 12 months with a
median improvement of 8.0 (IQR 6.0-12.3) at 6 and/or 12 months (n=34). Six months following implantation, there was a
positive correlation between quality-of-life and CNC (r=0.248, p=0.029) and AzBio in quiet (r=0.300, p=0.011), and at 12
months, there was a positive correlation between quality-of-life and CNC (r = 0.343, p<0.001), AzBio in quiet (r=0.291,
p=0.006), and AzBio in noise (r=0.290, p=0.046) scores. Patients who met benchmark CNC scores scored significantly greater
on CIQOL-10 than those who did not at 6 months (33.7 vs 29.6, p=0.009) and 12 months (34.2 vs 29.5, p=0.001). Those who
met benchmark AzBio scores demonstrated a similar relationship with CIQOL-10 at both 6 (33.8 vs 29.0, p=0.007) and 12
months (33.8 vs 29.8, p=0.010).
Conclusions: CIQOL-10 and speech recognition outcomes are positively correlated 6 and 12 months after CI. Patients who met
benchmark speech recognition scores had significantly greater quality-of-life scores.
Professional Practice Gap & Educational Need: The relationship between the validated CIQOL-10 and speech recognition
outcomes has yet to be established. There is also a lack of knowledge regarding the quality of life for those who meet benchmark
score on speech recognition measures versus those who do not meet benchmark scores.
Learning Objective: Attendees will understand the relationship between quality of life and speech recognition scores and be
able to compare quality of life scores for those who meet benchmark speech recognition measures scores and those who do not.
Desired
Results: Attendees will recognize that there is a positive correlation between CIQOL-10 and speech recognition
outcomes post-cochlear implantation. They will also understand that those who are meet benchmark scores have higher quality
of life than those who do not meet benchmark scores.
