What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This study looks at oxygen levels in adults over 65 after hip fracture surgery, comparing regional (spinal) anesthesia to general anesthesia. Researchers will measure oxygen saturation and track complications like sleep apnea, delirium, and hospital stay length. The study is observational, meaning it does not change patient care—it only collects data from routine procedures.

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 successful, this study could help doctors choose the best anesthesia type for older adults with hip fractures to improve breathing and recovery.
What could go wrong
This is a small observational study, not a treatment trial. It only measures oxygen levels and cannot prove which anesthesia is better. Results may not apply to all patients.
