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

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 Results may not be published yet.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

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

Summary

This study investigates whether people with acute decompensated heart failure are taking their prescribed medications as directed. Researchers will test urine samples from 100 patients at the emergency department to directly measure drug levels, and use questionnaires to explore factors like anxiety and depression that may affect adherence. The goal is to understand how often medication non-adherence contributes to heart failure episodes requiring emergency care.

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 this study finds that many heart failure patients are not taking their medications, it could lead to better support and education to improve adherence and prevent hospital visits.
What could go wrong
This is a small, single-center study that only measures adherence at one point in time. It cannot prove whether poor adherence directly caused the heart failure episode.
