Checking risk factors for urinary and related issues
This study looks at why some adults with spinal dysraphism develop problems with bladder, bowel, and/or sexual function. It gathers information during a one-day visit to help doctors better understand risk factors.
ParisAges 18 years+ - NCT06366828Recruiting
Predicting complications after esophageal cancer treatment
This study looks at past medical records of people with esophageal cancer who received chemotherapy and radiation before surgery. Researchers want to find better ways to predict who might have complications after surgery, so they can improve care for future patients.
Nijmegen, GelderlandAges 18–100 - NCT05692778Recruiting
Care program for people with diabetes and foot problems
This trial is testing an improved care approach for people with diabetes who have foot complications, delivered through primary care. It may help by organizing care more effectively and supporting better diabetes and foot management.
GothenburgAges 18 years+ - NCT06412367Recruiting
Walk test to plan for surgery
This trial uses a simple 6-minute walk test to see how well you can function before surgery. The goal is to help doctors plan better and reduce problems after surgery.
Toronto, OntarioAges 40 years+ - NCT03307018Recruiting
Check if bronchoscopy after lung surgery prevents complications
This study looks at whether doing a brief breathing-tube exam (bronchoscopy) after specific lung surgery can lower the chance of lung complications. It may help improve recovery and reduce post-surgery breathing problems.
Poznan, WielkopolskaAges 18–89 - NCT06550479Recruiting
Comparing three types of arm fistulas for dialysis
This trial compares three types of surgical connections (fistulas) between an artery and a vein in the arm, used for dialysis. It looks at which type works best for people with advanced kidney disease who need a new access point for dialysis.
WroclawAges 18 years+ - NCT07752173Recruiting
Recovery from breathing tube after surgery: day vs night
This study compares how well patients recover from the breathing tube (extubation) after surgery, depending on whether it happens during the day or at night. The goal is to see if there are more breathing complications at night so hospitals can improve care.
Kocaeli, IzmıtAges 18 years+ - NCT05679024RecruitingPhase 3
Apixaban to prevent stroke in atrial fibrillation and kidney failure
This trial tests apixaban (a blood thinner) to prevent stroke in people with atrial fibrillation or atrial flutter who have very poor kidney function or are on dialysis. If you qualify, you may help researchers find a safer way to lower stroke risk for this higher-risk group.
HelsinkiAges 18 years+ - NCT07729319Recruiting
Heat and moisture during lung surgery: a study
This study looks at whether a special device that adds heat and moisture to the air you breathe during surgery can help people who have lung surgery through small incisions (VATS). If you are having planned lung surgery that requires one-lung ventilation, you may be able to join.
Istanbul, IstanbulAges 18–75 - NCT06396767Recruiting
Breathing test before heart surgery to predict lung problems
This study uses a simple breathing test before scheduled heart surgery to see if it can help predict breathing or lung complications after the operation. The results may help doctors identify patients who need extra support during recovery.
London, OntarioAges 19–99 - NCT07715500Recruiting
MRI of Bile Ducts in Living Liver Donors
This study uses an MRI scan to look at the bile ducts in healthy people who want to donate part of their liver. The goal is to see if the scan can help predict and prevent bile duct problems for the person receiving the liver.
New DelhiAges 18–55 - NCT04331249Recruiting
Monitoring heart device during and around your procedure
This trial looks at how to manage and check implanted heart devices (pacemakers/defibrillators) during and around a planned procedure. It may help teams improve safety and decision-making during surgery or catheter procedures.
Fürth, BavariaAges 18 years+ - NCT05560802Recruiting

Common questions
- Are there clinical trials for complication?
- Yes. Clin2 currently lists 1,080 recruiting complication studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a complication trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a complication trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
