“…Absolute differences between hearing conditions for the disyllabic word recognition for Groups A, B, and C and their statistical significance. Differences are expressed in % of correct disyllabic words throughout the follow-up period is comparable with the recognition observed in a population with bilateral P-SNHL and unilateral implantation [28][29][30] .…”

Importance: Sensorineural hearing loss is the third leading cause of years lived with disability worldwide. Cochlear implants may provide a viable alternative to hearing aids for this type of hearing loss. The Coverage and Analysis Group at the Centers for Medicare & Medicaid Services was interested in an evaluation of recently published literature on this topic. In addition, this metaanalysis is to our knowledge the first to evaluate qualityof-life (QOL) outcomes in adults with cochlear implants.Objective: To evaluate the communication-related outcomes and health-related QOL outcomes after unilateral or bilateral cochlear implantation in adults with sensorineural hearing loss. Study Selection: Published studies of adult patients undergoing unilateral or bilateral procedures with multichannel cochlear implants and assessments using openset sentence tests, multisyllable word tests, or QOL measures.Data Extraction: Five researchers extracted information on population characteristics, outcomes of interest, and study design and assessed the studies for risk of bias. Discrepancies were resolved by consensus.Results: A total of 42 studies met the inclusion criteria. Most unilateral implant studies showed a statistically significant improvement in mean speech scores as measured by open-set sentence or multisyllable word tests; meta-analysis revealed a significant improvement in QOL after unilateral implantation. Results from studies assessing bilateral implantation showed improvement in communication-related outcomes compared with unilateral implantation and additional improvements in sound localization compared with unilateral device use or implantation only. Based on a few studies, the QOL outcomes varied across tests after bilateral implantation. Conclusions and Relevance:Unilateral cochlear implants provide improved hearing and significantly improve QOL, and improvements in sound localization are noted for bilateral implantation. Future studies of longer duration, higher-quality reporting, and large databases or registries of patients with long-term follow-up data are needed to yield stronger evidence.

INTRODUCTIONHearing loss is prevalent in one in three people over the age of 50, and two-thirds of those older than 70 years. 1 Hearing loss in older adults impairs verbal communication, contributes to social isolation, 2 and has been independently associated with poorer cognitive functioning [3][4][5] and incident dementia. [6][7] While hearing aids improve audibility for most individuals with mild to moderate hearing loss, those who suffer from severe to profound hearing loss generally may acquire greater benefit from electrical hearing provided by a cochlear implant (CI). 8 Currently, the number of older adults in the United States who would potentially meet audiologic criteria for a CI is approximately 150,000, 1 but less than 5% of these older adults are likely to have received a CI System. 9 Many factors could potentially account for the low rate of CI use in older adults, such as a general perception of hearing loss being an inconsequential part of aging and poor awareness of and access to cochlear implantation. Additionally, there are concerns about whether older adults could practically benefit from CI on a daily basis. Older adults can consistently acquire improved speech perception scores after CI in the clinical setting, 10 but patterns of CI use by older adults has received little review. Previous studies have reported results only in small cohorts of older adults with limited durations of follow-up. [11][12][13][14][15][16][17][18] The purpose of our study was to investigate long-term rates of CI use in a consecutive case series of older adults (≥60 years) who received their first CI from 1999-2011. MATERIALS AND METHODS STUDY COHORTWe queried the Johns Hopkins Listening Center database to retrieve all patients ≥ 60 years who received a first CI from 1999 to June 2011 (n = 447). The purpose of this study was to investigate rates of CI use in older adults which is generally defined by the United Nations as adults ≥ 60 years. 33 Of these patients, we were able to successfully obtain follow-up information from the patient or a proxy respondent for 397 individuals (89%) from June to August 2012, and these individuals comprise our analytic cohort. Characteristics of "responders" (n = 397) and "non-responders" (n = 50) did not differ significantly by age of implantation, onset of hearing loss, side of implantation, or manufacturer (data not shown). Non-responders were more likely to have been implanted earlier in the study time period than responders (p < .001). Of the 50 non-responders, 27 (54%) had died based on Social Security Death Index records. For these deceased non-responders, we were unable to obtain proxy information on their CI use at the time of death due to unavailable contact information for surviving family members. This study was approved by Johns Hopkins Institutional Review Board. DATA COLLECTION ON CI USEAs part of a quality assurance initiative at the Johns Hopkins Listening Center, we contacted all CI patients and their families to survey their daily CI use.
