The effect of psychosocial factors on outcomes of cochlear implantation

Satisfaction with life in a sample of prelingually deaf cochlear implant users with a good command of spoken Polish as the primary language

INTRODUCTION

This study investigated the level of satisfaction with life (SWL) in a group of cochlear implant (CI) users who had been prelingually deaf but were orally educated. They had received one or two CIs (as a child, adolescent, or adult) and were highly competent Polish speakers. This study looked at three factors that may affect SWL - psychosocial, deafness/hearing and communication related, and sociodemographic.

METHODS

The participants were prelingually deaf CI users who had learned highly competent spoken Polish as their primary language. They had been educated in mainstream or integrated schools (not schools for the deaf), and had no other disability or severe illness. Measurements were done with 5 questionnaires: the Satisfaction With Life Scale (SWLS), the I-Others Questionnaire, the Patient Health Questionnaire (PHQ-9), the Deaf Identity Development Scale (DIDS), and the Nijmegen Cochlear Implant Questionnaire (NCIQ).

RESULTS

The SWL level of the group was similar to that of the standard Polish population. SWL was positively related to positive self-perception, acceptance of oneself as a deaf person, and to perceiving the benefits of having a CI (as measured by three NCIQ domains: self-esteem, activity limitations, and social interactions). On the other hand, negative self-perception, marginal deaf identity, and depressive symptoms were negatively related to SWL. There was no relationship between SWL and knowledge of sign language. Lower depressive symptoms and greater hearing loss were both significant predictors of SWL, although those who used two CIs generally had a lower SWL.

CONCLUSIONS

Prelingually deaf CI users with low SWL require psychological support in many spheres, including working through problems of deaf identity, self-acceptance, and depression. Additional research should involve diverse DHH CI users, including those with limited spoken Polish competency or sign language skills, as well as members of the Polish Deaf community.

Enhancing socio-emotional communication and quality of life in young cochlear implant recipients: Perspectives from parameter-specific morphing and caricaturing

The use of digitally modified stimuli with enhanced diagnostic information to improve verbal communication in children with sensory or central handicaps was pioneered by Tallal and colleagues in 1996, who targeted speech comprehension in language-learning impaired children. Today, researchers are aware that successful communication cannot be reduced to linguistic information—it depends strongly on the quality of communication, including non-verbal socio-emotional communication. In children with cochlear implants (CIs), quality of life (QoL) is affected, but this can be related to the ability to recognize emotions in a voice rather than speech comprehension alone. In this manuscript, we describe a family of new methods, termed parameter-specific facial and vocal morphing. We propose that these provide novel perspectives for assessing sensory determinants of human communication, but also for enhancing socio-emotional communication and QoL in the context of sensory handicaps, via training with digitally enhanced, caricatured stimuli. Based on promising initial results with various target groups including people with age-related macular degeneration, people with low abilities to recognize faces, older people, and adult CI users, we discuss chances and challenges for perceptual training interventions for young CI users based on enhanced auditory stimuli, as well as perspectives for CI sound processing technology.

[Measuring the cochlea using a tablet-based software package: influence of imaging modality and rater background]

BACKGROUND

Cochlear duct length (CDL) is subject to significant individual variation. In the context of cochlear implantation, adapting the electrode array length to the CDL is of potential interest, as it has been associated with improvements in both speech recognition and sound quality. Using a tablet-based software package, it is possible to measure CDL at the level of the organ of Corti (CDL_OC) to select appropriate electrode array lengths based on individual cochlear anatomy.

OBJECTIVE

To identify effects of imaging modality and rater background on CDL estimates.

METHODS

Magnetic resonance imaging (MRI) and flat-panel volume CT (fpVCT) scans of 10 patients (20 cochleae) were analyzed using the OTOPLAN software package (MED-EL, Innsbruck, Austria). Raters were an otorhinolaryngology (ORL) specialist, an ORL resident, and an audiologist. To analyze effects of rater background and imaging modality on CDL measurements, linear mixed models were constructed.

RESULTS

Measurements showed mean CDL_OC(fpVCT) = 36.69 ± 1.78 mm and CDL_OC(MRI) = 36.81 ± 1.87 mm. Analyses indicated no significant effect of rater background (F(2, 105) = 0.84; p = 0.437) on CDL estimates. Imaging modality, on the other hand, significantly affected CDL (F (1, 105) = 20.70; p < 0.001), whereby estimates obtained using MRI were 0.89 mm larger than those obtained using fpVCT.

CONCLUSION

No effect of rater background on CDL estimates could be identified, suggesting that comparable measurements could be obtained by personnel other than specially trained neurootologists. While imaging modality (fpVCT vs. MRI) did impact CDL results, the difference was small and of questionable clinical significance.

Systematic Review on Late Cochlear Implantation in Early-Deafened Adults and Adolescents: Clinical Effectiveness

OBJECTIVES

Cochlear implantation in early-deafened patients, implanted as adolescents or adults, is not always advised due to poor expected outcomes. In order to judge whether such reluctance is justified, the current systematic review aimed to gather all available evidence on postoperative outcomes obtained by early-deafened patients using a state-of-the art cochlear implant (CI).

DESIGN

Five electronic databases (PubMed, Embase, the Cochrane library, CINAHL, and PsycInfo) were systematically searched for studies in English, French, German, or Dutch, published between 2000 and September 2017. Studies that reported pre- and postoperative outcomes on any measure of speech or sound perception, audiovisual or subjective benefit (quality of life) were included. Study quality was assessed with the Institute of Health Economics quality appraisal tool for case series studies.

RESULTS

The systematic search and subsequent full-text evaluation identified 38 studies meeting the inclusion criteria. Only a limited number of studies were judged to be of high quality according to the Institute of Health Economics tool, with lack of (clear) presentation of relevant study information being a recurring problem. Twenty-five studies presented viable outcomes on open-set speech understanding in quiet: mean postoperative scores obtained with CI remained below 50% for the vast majority of studies; significant postoperative improvements were found in 16 studies, although this number might have been higher if appropriate statistical testing had been performed in all studies. Eight studies observed increased audiovisual performance after implantation, which was statistically significant in six studies. A validated measure of hearing-related quality of life was used in only 5 of the 16 studies assessing subjective outcomes, showing significant postoperative improvements for most questionnaire domains. The relation between auditory and subjective outcomes was assessed in two studies, with contradictory results.

CONCLUSIONS

The current review showed that late cochlear implantation in early-deafened subjects resulted in significantly improved open-set speech perception, audiovisual speech perception, and (hearing-related) quality of life in the majority of the studies involved. Nonetheless, more and especially higher-quality research is needed in order to gain a more detailed understanding of the outcomes of cochlear implantation in this population.

Cochlear implants in adults with partial deafness: subjective benefits but associated psychological distress

Purpose

The present study investigated adults with partial deafness (PD) and asked them to rate the benefits of their cochlear implant (CI), their general level of satisfaction with it, and their level of psychological distress. Of particular interest was the role of gender.

Methods

The study comprised 71 participants (41 females) with PD who had been provided with a CI. The Nijmegen Cochlear Implant Questionnaire (NCIQ) was used to assess the benefits of their CI. Satisfaction with their CI was measured using a visual analog scale. The severity of mental distress was assessed with the General Health Questionnaire (GHQ-28).

Results

On various NCIQ scales, the average benefits of a CI were rated at 66%. Females gave a lower rating than males. The mental distress experienced by the group was significantly higher than in the general population. Females had more severe symptoms of anxiety and insomnia than males. There was a significant relationship between psychological distress and CI benefit, but only in females. Besides general distress, the most affected spheres were related to psychosocial functioning—“self-esteem”, “activity limitation”, and “social interaction”. Contrary to expectations, there was no relationship between mental distress and CI satisfaction.

Conclusions

The perceived benefits of a CI in subjects with PD relate mostly to the level of mental distress, although gender is an important factor. For females, their emotional state affects how beneficial their CI is perceived. Due to the higher levels of mental distress, females tend to need more psychological intervention and support.

Patients with psychiatric illness report worse patient-reported outcomes and receive lower rates of autologous breast reconstruction

Psychiatric well-being impacts on general satisfaction and quality of life. This study explored how the presence of psychiatric diagnoses affects patient-reported outcomes in breast reconstruction and on selection of reconstructive modality. Patients who received breast reconstruction at a tertiary hospital between 2013 and 2018 and completed the BREAST-Q survey were included. BREAST-Q module scores were compared between patients who had a psychiatric diagnosis at presentation and the remaining cohort using t tests. General linear models (GLMs) were used to control for confounding factors. A chi-squared test was used to assess the effect on reconstructive modality, and binary logistic regression was used to control for confounding factors. Of the 471 patients included, 93 (19.7%) had at least one psychiatric diagnosis. Cohorts did not differ significantly by age, BMI, race, ASA classification, or insurance status. Patients with a psychiatric diagnosis experienced a decrease in BREAST-Q scores for the Psychosocial Wellbeing (B = 9.16, P = .001) and Sexual Wellbeing (B = 9.29, P = .025) modules. On binary logistic regression, patients with a psychiatric diagnosis were less likely to receive autologous reconstruction compared with implant reconstruction (OR = 0.489, P = .010). The presence of psychiatric diagnoses is an independent predictor of decreased BREAST-Q. Furthermore, there is a significant disparity in modality of reconstruction given to patients with psychiatric diagnoses. Further study is needed to evaluate interventions to improve satisfaction among at-risk populations and evaluate the reason for low autologous reconstruction in this population.

The Outcome of Unilateral Cochlear Implantation in Adults: Speech Recognition, Health-Related Quality of Life and Level of Anxiety and Depression: a One- and Three-Year Follow-Up Study

Introduction  Hearing impairment is a common disease worldwide, with a comprehensive impact, and cochlear implantation (CI) is an intervention for profound hearing impairment.

Objective  To study the outcome one and three years after unilateral CI on hearing, health-related quality of life and level of depression and anxiety, and the correlation between the outcomes. Second, to study whether age, gender, etiology, operated side, residual hearing or cognitive performance can predict the outcome.

Methods  A prospective longitudinal study including adults with profound postlingual hearing impairment, with respect to hearing (speech recognition), health-related quality of life (Health Utilities Index 3) and level of depression and anxiety (Hospital Anxiety and Depression scale), pre-CI, and one and three years post-CI. The total sample was composed of 40 participants (40% of men), with a mean age of 71 years.

Results  Speech recognition and the overall health-related quality of life improved one year post-CI ( p  = 0.000), without correlation (ρ= 0.27), and with no difference three years post-CI. The hearing attribute (in the health-related quality of life instrument) improved one and three years post-CI ( p  = 0.000). The level of anxiety did not change one and three years post-CI. The level of depression improved one year post-CI ( p  = 0.036), and deteriorated three years post-CI ( p  = 0.031). Age, etiology, operated side, residual hearing and cognitive performance did not predict the outcome, but the female gender did significantly improve speech recognition compared with men ( p  = 0.009).

Conclusion  The CI significantly improved speech recognition, health-related quality of life and level of depression one year post-CI without mutual correlation, and women performed significantly better than men. There were no further improvements three years post-CI, apart from the hearing attribute.

A Comparison of Surgical Auditory Nerve Response and Speech Outcomes in Patients with Post-meningitic Deafness and Without Cochlear Osteogenesis Who Underwent Cochlear Implantation

Objective

Patients with post-meningitis deafness remain challenging candidates for cochlear implantation (CI) which can be difficult due to fibrosis or ossification of the inner ear, and their outcomes remain doubtful. We assessed the surgical and audiological outcomes of CI in patients with profound sensorineural hearing loss caused by meningitis and compared those outcomes to patients without cochlear ossification.

Methods

This retrospective cross-sectional study was carried out at King Fahad General Hospital, Jeddah, Saudi Arabia. Among 246 patients who underwent cochlear implantation, 13 patients with post-meningitic deafness were identified (Group 1). A matched control group, including patients with deafness due to other causes who did not have cochlea osteogenesis, was selected (Group 2). For all patients, data were collected from medical records, including surgical and audiological outcomes.

Results

Sclerosis of the cochlea was high in Group 1 (46.2%). There were no postoperative surgical complications in either group. Responses of the auditory nerve action potential obtained through auditory response telemetry (ART) or the neural response telemetry (NRT) were recorded. There was no significant difference between the two groups regarding the intraoperative and the postoperative ART or NRT at selected electrodes representing the entire cochlea. Likewise, no significant difference regarding the speech recognition test (SRT) was detected.

Conclusions

Cochlear implantation is a safe procedure without surgical complications in post-meningitis patients. Furthermore, early CI in children was associated with favorable outcomes in terms of preservation of the auditory nerve response, restoration of speech discrimination, and recognition to levels comparable to patients with deafness due to other causes. Early audiological assessment in meningitis patients is recommended to identify hearing loss and eventually to offer CI.

Prognostic value of psychological state in cochlear implantation

CONCLUSION

Perioperative Minnesota Multiphasic Personality Inventory (MMPI) scores may be beneficial for predicting prognosis of cochlear implantation (CI). A positive attitude for social interaction in particular correlates with a better speech outcome. Proper perioperative psychological management may, therefore, assist in the auditory rehabilitation of CI patients.

OBJECTIVE

To determine the perioperative psychological state of CI patients and its relationship with patient prognosis after CI.

METHODS

This study prospectively enrolled 29 patients who underwent CI from 2005-2013. The MMPI was administered to assess psychosocial and emotional issues surrounding CI and the Korean version of the Central Institute of Deafness (K-CID) score was used to measure speech perception.

RESULTS

CI resulted in a significant improvement on the MMPI Paranoia scale (p = 0.02). Patients with abnormal pre-operative and post-operative MMPI scores also had an earlier onset of deafness, longer duration of deafness, and lower K-CID scores than patients with normal MMPI scores (all p < 0.05). The post-CI K-CID score had a significant negative correlation with the pre-operative MMPI Schizophrenia score (p < 0.01) and significant negative correlations with the post-operative MMPI Paranoia (p = 0.02), Psychasthenia (p = 0.02), Schizophrenia (p = 0.04), Hypomania (p = 0.02) and Social Introversion (p = 0.03) scores.
