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.

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 analyzes data from 425,000 adults who had non-cardiac surgery under general anesthesia. Researchers want to see if a measure called the perfusion index, which reflects blood flow in the fingers, is linked to the risk of dying after surgery. The goal is to find out if this simple monitoring tool can help predict serious outcomes like death or ICU admission.

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 could help doctors identify high-risk patients during surgery and potentially improve monitoring to reduce complications.
What could go wrong
This is an observational study using existing data, so it can only show links, not cause and effect. The results may not change practice directly.

This is an AI summary of the original study and may miss details. Read our disclaimer.
