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
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 This study
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 Results may not be published yet.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.

Summary

Researchers are analyzing records from about 180,000 people who received cochlear implants in China between 1995 and 2026. The study aims to map how severe hearing loss and implant use have changed over time, how age and gender patterns look, and how patients move between provinces for surgery. It also examines how price cuts and insurance policies have affected access, and estimates how many more people might need implants under different coverage scenarios.

What this could mean

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

What this could lead to
If the analysis succeeds, it could give health officials a clearer picture of who gets cochlear implants in China and where services fall short, which may help shape hearing care policy and funding.
What could go wrong
This study looks back at existing records rather than testing a treatment, so it cannot prove that any policy caused a change in implant use. Missing or inconsistent records across 30 years and many provinces could limit what the numbers can show.
