Predictors of Short-Term Changes in Quality of Life after Cochlear Implantation

[Cochlear implants reduce tinnitus in older patients in the long term]

BACKGROUND

Tinnitus is one of the most common otologic comorbidities, particularly in older patients with severe hearing loss or deafness. Cochlear implants (CI) have been used for hearing rehabilitation more and more successfully in elderly patients and CI treatment is performed in Germany without an age limit. The aim of this follow-up study was to assess the tinnitus burden in the long-term follow-up of elderly patients with hearing rehabilitation using CI.

MATERIAL AND METHODS

This prospective longitudinal study included 15 patients between 72 and 92 years of age with preoperative tinnitus who had been treated unilaterally with a CI for the first time about six years ago. Monosyllabic speech understanding and tinnitus burden were assessed using the Mini-Tinnitus Questionnaire. The results were compared with our previous study 24, focusing on the first six months.

RESULTS

Six years postoperatively, there was a nonsignificant increase in monosyllabic understanding to 61.7 ± 26.3%, compared with the results six months postoperatively (p = 0.069). The burden of tinnitus showed a stable low mean of 3.9 ± 3.6 points six years postoperatively, compared with the six-month control (p = 0.689) and significantly reduced compared to the preoperative status with 6.9 ± 6.5 points (p = 0.016).

CONCLUSION

Hearing rehabilitation by using CI leads to a stable improvement of monosyllabic discrimination in elderly people as well as to a stable reduction of tinnitus burden over years.

Assessment of Cochlear Implant Rehabilitation Success by Speech-Language Therapists Using International Classification of Functioning, Disability and Health Criteria

PURPOSE

This study aims to introduce an assessment questionnaire based on the International Classification of Functioning, Disability and Health (ICF) to enable quantifiable clinical documentation. The questionnaire assists speech-language therapists (SLTs) in evaluating both non-audiological and audiological rehabilitation outcomes of patients with cochlear implants (CIs).

METHOD

Six SLTs were recruited to evaluate the effectiveness of CI care using ICF criteria. We carefully selected 20 pertinent ICF criteria, and SLTs received thorough training in how to apply them uniformly. A cohort of 48 patients was evaluated at three distinct time points: presurgery, postsurgery, and 6 months post-initial CI fitting. Patients underwent dedicated speech-language therapy sessions throughout the treatment course.

RESULTS

A total of 144 complete datasets were scrutinized using a two-factor analysis of variance for ranks. Following CI care, patients exhibited substantial improvements in auditory perception, characterized by enhanced sound recognition and speech discrimination. Additionally, patients demonstrated improved attentional focus, proficiency in daily tasks and increased conversational engagement over time. Environmental factors, particularly sound perception, improved markedly, correlating with reported reductions in stress levels. Minimal changes were noted in stress management and communication techniques. Articulatory function, speech functions, and pain perception exhibited the least alteration.

CONCLUSIONS

The data extracted from the ICF-based assessments underscore the vital significance of incorporating speech therapy-based metrics to evaluate both non-audiological and audiological factors in assessing the success of CI care within the SLTs domain. This approach proves to be highly relevant both in terms of demonstration and clinical applicability.

Holistic assessment of cochlear implant outcomes using the international classification of functioning disability and health model: data analysis of a longitudinal prospective multicenter study

PURPOSE

To study outcome after cochlear implantation using the Cochlear Implant (CI) outcome assessment protocol based on the International Classification of Functioning, Disability and Health (ICF) model (CI-ICF).

METHODS

Raw data of a prospective, longitudinal, multicenter study was analyzed. Seventy-two CI candidates were assessed preoperatively and six months postoperatively using the CI-ICF protocol. Following tools were used: (1) Work Rehabilitation Questionnaire (WORQ), (2) Abbreviated Profile of Hearing Aid Benefit (APHAB), (3) Audio Processor Satisfaction Questionnaire (APSQ), (4) Speech, Spatial, and Qualities of Hearing Scale (SSQ12), (5) Hearing Implant Sound Quality Index (HISQUI19), (6) Nijmegen CI Questionnaire (NCIQ) (7) pure tone audiometry, (8) speech audiometry, (9) sound localization.

RESULTS

There was a significant improvement of speech discrimination in quiet (p = 0.015; p < 0.001) and in noise (p = 0.041; p < 0.001), sound detection (p < 0.001), tinnitus (p = 0.026), listening (p < 0.001), communicating with-receiving-spoken messages (p < 0.001), conversation (p < 0.001), family relationships (p < 0.001), community life (p = 0.019), NCIQ total score and all subdomain scores (p < 0.001). Subjective sound localization significantly improved (p < 0.001), while psychometric sound localization did not. There was no significant subjective deterioration of vestibular functioning and no substantial change in sound aversiveness. CI users reported a high level of implant satisfaction postoperatively.

CONCLUSION

This study highlights the positive impact of cochlear implantation on auditory performance, communication, and subjective well-being. The CI-ICF protocol provides a holistic and comprehensive view of the evolution of CI outcomes.

Quality of Life With Cochlear Implantation Using the CIQOL-35 at a Tertiary Urban Medical Center: Our Experience

OBJECTIVE

Assessment of quality-of-life (QOL) outcomes after cochlear implantation (CI) using the Cochlear Implant Quality of Life-35 questionnaire (CIQOL-35).

STUDY DESIGN

Retrospective cohort.

SETTING

Single-institution tertiary care center.

PATIENTS

Patients 18 years and older who have undergone CI and CIQOL-35 survey.

INTERVENTIONS

Implementing CIQOL-35 from 2019 to 2022 to measure change in QOL after CI. Statistical analysis included nonparametric, univariate, and multivariate analyses. Significance was set at 0.05.

MAIN OUTCOME MEASURES

Differences in QOL among CI patients in each of the CIQOL-35 domains.

RESULTS

Ninety-three patients (40 female, 53 male) aged 20 to 93 years (median 70 years) turned in 164 QOL surveys (68 preactivation, 96 postactivation). Postactivation median QOL was 5 to 15 points higher across all domains ( p < 0.001). QOL score distributions among unilateral CI only, bilateral CI, and unilateral CI with contralateral hearing aid users were not statistically different ( p > 0.05). Multivariate analysis identified that male sex ( β = -2.0; 95% confidence interval, -3.9 to -0.1) was a negative predictor for environment scores and not being married ( β = 2.0; 95% confidence interval, 0.02 to 4.0) was a positive predictor for entertainment scores. Median follow-up time was 13 months post-CI (interquartile range [IQR], 7.1-21.5 months).

CONCLUSIONS

CI patients experienced improved QOL postactivation among all QOL domains, whereas specific CI use pattern in regard to unilateral, bilateral, or bimodal did not affect QOL. Multivariate analysis identified marital status and sex as possible QOL predictors.

Influence of depressive disorders, stress, and personality traits on quality of life after cochlear implantation

PURPOSE

This study aimed to determine whether preoperative depressiveness, stress, and personality influence quality of life (QOL) after cochlear implant (CI) surgery.

METHODS

In this prospective study, 79 patients undergoing CI surgery were evaluated preoperatively and 12 months postoperatively. Disease-specific QOL was assessed with the Nijmegen Cochlear Implant Questionnaire (NCIQ) and general QOL with the WHOQOL-BREF. Depressiveness and stress were assessed with the Patient Health Questionnaire (PHQ-D). The Charlson Comorbidity Index (CCI) was used to classify comorbidities. The Big Five Personality Test (B5T) was used to assess the basic personality dimensions. Speech comprehension was evaluated in quiet with the Freiburg monosyllable test and in noise with the Oldenburg sentence test.

RESULTS

After CI surgery, the total NCIQ score improved significantly (Δ 17.1 ± 14.7, p < 0.001). General QOL (WHOQOL-BREF, Δ 0.4 ± 9.9, p = 0.357), stress (Δ 0.25 ± 3.21, p = 0.486), and depressiveness (Δ 0.52 ± 3.21, p = 0.121) were unaffected by CI surgery. Patients without elevated depressiveness (p < 0.01) or stress (p < 0.001) had significantly better total NCIQ scores. The results of the multiple regression analyses show that, after adjusting for the CCI, personality, age, and mental health stress (ß = - 0.495, p < 0.001) was significantly associated with postoperative NCIQ outcome scores. Depressiveness and neuroticism had the strongest influence on the generic QOL (ß = - 0.286 and ß = - 0.277, p < 0.05).

CONCLUSION

Stress symptoms and personality traits are significant predictive factors for disease-specific QOL, as well as hearing status. This should be considered in the preoperative consultation and in optimizing the rehabilitation process.

Correlation Between Quality of Life and Speech Recognition Outcomes Following Cochlear Implantation

OBJECTIVE

To study the relationship between Cochlear Implant Quality of Life-10 Global (CIQOL-10) scores and speech recognition scores 6 and 12 months after cochlear implantation (CI) and to compare CIQOL-10 scores for patients who met the benchmark speech recognition scores with those who did not.

STUDY DESIGN

Retrospective review.

SETTING

Tertiary referral center.

PATIENTS

One hundred twenty-four adults who underwent CI between 2018 and 2021 and completed a CIQOL-10 questionnaire at their 6- and/or 12-month postoperative visit.

MAIN OUTCOME MEASURES

CIQOL-10, Consonant-Nucleus-Consonant (CNC) word, and AzBio in quiet and noise scores.

RESULTS

At 6 months, weak positive correlations were found between CIQOL-10 and CNC (n = 78, r = 0.234, p = 0.039) and AzBio in quiet (n = 73, r = 0.293, p = 0.012) scores but not AzBio in noise scores (n = 39, r = 0.207, p = 0.206). At 12 months, weak positive correlations were found between CIQOL-10 and CNC (n = 98, r = 0.315, p = 0.002), AzBio in quiet (n = 88, r = 0.271, p = 0.011), and AzBio in noise (n = 48, r = 0.291, p = 0.045) scores. Patients who met the benchmark CNC scores had notably higher CIQOL-10 scores than those who did not at 6 months (52.0 vs 45.5, p = 0.008) and 12 months (52.0 vs 45.5, p = 0.003). A similar relationship was found for those who met the benchmark AzBio in quiet scores at both 6 months (52.0 vs 44.0, p = 0.006) and 12 months (52.0 vs 46.5, p = 0.011).

CONCLUSION

CIQOL-10 scores have weak positive correlations with postoperative speech recognition outcomes at 6 and 12 months. This highlights the need for the continued use of quality-of-life measures, such as the CIQOL-10, in assessing CI outcomes to gain a more comprehensive understanding of patients' experiences.
