The Impact of the COVID-19 Pandemic on Real-world Functioning in Adult Cochlear-implant Users.

Hypothesis: As a result of COVID-19 lockdowns and the associated effects on the auditory-social environments of cochlear-implant (CI) users, we expected that adult CI users would report a decrease in real-world communication abilities, a decrease in social isolation, and a decrease in quality of life (QOL) from pre- to post-pandemic.

Background: The COVID-19 pandemic brought many changes to the environments in which adults with CIs interact and communicate. However, the impact of these changes on CI users' real-world functioning is not well understood. This study investigated the impact of the COVID-19 pandemic on real-world communication abilities, social isolation, and CI-related QOL in adult CI users.

Methods: Fourteen adult CI users completed self-report questionnaires assessing communication abilities, social isolation, and CI-related QOL at time points before and after the onset of the COVID-19 pandemic. Responses at the 2 time points were compared to evaluate changes in CI users' real-world functioning.

Results: Adult CI users showed a significant decrease in self-reported communication ability and a nonsignificant decline in CI-related QOL from before to during COVID-19. However, a nonsignificant trend of a decline in social isolation was also observed in adult CI users.

Conclusion: Findings showed a decrease in self-reported communication abilities and, to a lesser extent, CI-related QOL, suggesting that changes to the auditory-social environment brought on by the COVID-19 pandemic may have negatively impacted communication abilities in real-world, challenging environments. Yet, the potential decrease in social isolation suggests that these changes may have had an overall positive effect on social interaction, potentially with close family and friends in well-controlled environments. Assessing changes in real-world functioning in the same CI users from both before and during the COVID-19 pandemic provided a unique glimpse into how changes in the auditory-social environment may impact outcomes in adult CI users.
