Description of intervention(s) / exposure
Remote Check is a feature of the Nucleus Smart App which comprises of various tests, performance measurements, datalogging, and a set of questions requiring a subjective answer by the recipient or parent/carer on sound quality and other aspects of device use. Remote Check is designed to be easy to use for a cochlear implant recipient even if they have no prior experience in using the Nucleus Smart App. No training will be provided to the participants on the use of the app; however, they will have access to the guidance inbuilt in the app.
Participants will have access to the Remote Check feature of the app on the loaner Android smartphone for the maximum duration of the trial (6 months).
Remote Check in the Nucleus Smart App includes the following tests that can be run by the recipient or their parent/carer at home: photos of the implant site and surgical scar, questionnaire, Aided Threshold Test (ATT), Digit Triplet Test (DTT), Datalogs and Telemetry measurements. Results are intended to provide relevant information for a clinician to determine if the recipient needs to attend the clinic in-person or not. Primary tasks include participants identifying that a Remote Check is due in the Nucleus Smart App’s home screen, being able to start the Remote Check and proceed through the various tests as mentioned above.
Remote Check activities in this trial are expected to take 1-2 hours in clinic and 1-2 hours at home.
Remote Check is self-administered by the subject and results reviewed by a clinical audiologist.
The results of the Remote Check will be accessed via a web-portal by the investigator to review data. In addition, the diagnostics logs from the app will be collected to assess use errors.

Summary
Brief summary
The purpose of the feasibility pilot is to assess the ease of use of Remote Check on Android smart phones when used by adult Cochlear Implant recipients, in terms of usability and software issues, for the completion of primary tasks. Usability will be assessed using a ranking scale and questionnaire. Software issues/bugs relevant to the use of Remote Check on Android will be logged and used to inform any product enhancements required. The study will also characterise the test retest difference of Aided Threshold Test (AAT) and Digit Triplet Test (DTT) when streamed via Android smart phones.
