Can hospital codes reliably track home ventilation in ALS?

NCT ID NCT07819890

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers in Denmark are studying how well hospital codes identify ALS patients who use home mechanical ventilation, both invasive and noninvasive. The study includes about 400 patients with ALS and at least two hospital contacts between 2012 and 2026. By checking the accuracy of these codes, the team aims to describe how home ventilation has been used over time and the clinical characteristics of patients who receive it.

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 hospital codes prove accurate, researchers could use them to track how breathing support affects ALS patients across Denmark and plan better care.
What could go wrong
This study only checks records and does not test a treatment, so it cannot prove that ventilation changes outcomes. Coding errors or missing data could limit what the results show.
