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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 at Ankara Etlik City Hospital are studying whether the perfusion index, a blood-flow reading taken with a standard pulse oximeter, can predict the severity of diabetic ketoacidosis in adults arriving at the emergency department. The study will follow 140 patients aged 18 and older who are diagnosed with the condition. All patients receive routine care; the team records the perfusion index and serum lactate levels and compares how well each measure, and their ratio, predicts severity, intensive care needs, and outcomes such as length of stay and in-hospital mortality.

What this could mean

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

Active substance
perfusion index measured by pulse oximetry, compared with serum lactate
What this could lead to
If it works, emergency teams could gauge how severe a diabetic ketoacidosis case is within minutes using a finger sensor, without waiting for lab results.
What could go wrong
This is a single-center observational study of 140 patients, so it can only show an association, not prove the perfusion index causes or reliably predicts outcomes. The findings may not hold in other hospitals or patient groups.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18 years or older. 2. Diagnosis of diabetic ketoacidosis in the emergency department. 3. Ability to obtain perfusion index and serum lactate measurements during the initial assessment after admission. 4. Provision of written informed consent by the patient or, when necessary, the patient's legally authorized representative. Exclusion Criteria: 1. Pregnancy. 2. Trauma, major bleeding, or hemorrhagic shock. 3. Cardiac arrest. 4. Conditions that may prevent reliable perfusion index measurement, including advanced hypothermia, severe peripheral arterial disease, or amputation, burns, severe edema, or deformity at the measurement site. 5. Advanced chronic liver failure. 6. End-stage renal disease or dialysis treatment. 7. Inability to obtain the essential study variables or presence of missing data. 8. Refusal to participate in the study. 9. Repeat emergency department presentation by the same participant; only the first presentation will be included.
