What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks back at the medical records of about 700 people who received a MED-EL cochlear implant to see how well they hear over time. Researchers will examine speech understanding in quiet and noisy settings, as well as patient-reported outcomes, and check for any device-related complications. The goal is to gather real-world evidence on the long-term effectiveness and safety of these implants.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cochlear implant (a device that provides artificial hearing to people with severe to profound hearing loss)
What this could lead to
If successful, this could provide stronger evidence on how well cochlear implants work over many years, helping guide future treatment decisions and device improvements.
What could go wrong
Because this is a retrospective review of existing data, it cannot prove cause and effect. Results may be limited by missing or inconsistent data from routine clinical care.
