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
Paused for now. It may or may not start again.
Ongoing This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study looks at whether a computer model can predict heart injury after major orthopedic surgery in patients 65 and older. Researchers will combine blood tests, frailty scores, and other health data to build a machine learning tool. The goal is to help doctors spot high-risk patients before surgery, but this is an observational study and does not test a new treatment.

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 lead to a tool that helps doctors identify elderly patients at high risk of heart injury before surgery, allowing for better planning and care.
What could go wrong
This is an observational study, not a treatment trial. The model may not work perfectly in all hospitals or patient groups, and it does not directly improve outcomes.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of geriatric patients (aged 65 years) undergoing major orthopedic surgery and requiring postoperative intensive care unit follow-up. Eligible participants must have at least one cardiac troponin level measured within the first 72 hours postoperatively. Patients on chronic dialysis due to end-stage renal disease and those with insufficient preoperative laboratory data will be excluded. The population is selected to represent high-risk geriatric patients in a tertiary training and research hospital setting

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

Inclusion Criteria: * All patients aged 65 years and older. * Patients undergoing major orthopedic surgery (hip fracture repair, total knee/hip arthroplasty, and revision surgeries). * Patients operated on within the designated study period (January 2021 - December 2023). * Patients with complete access to preoperative clinical data (comorbidities, medication use) and baseline laboratory parameters (Hemoglobin, Creatinine, Albumin). * Patients who had at least one postoperative cardiac troponin (hs-cTn) measurement within the first 72 hours after surgery. Exclusion Criteria: * Patients with a documented history of acute myocardial infarction or elevated baseline troponin levels in the preoperative period (to differentiate acute injury from surgical causes). * Patients with end-stage renal disease (ESRD) requiring dialysis (as chronic kidney dysfunction persistently elevates baseline troponin levels). * Patients with missing critical preoperative data or incomplete postoperative troponin follow-up.
