Preoperative urine infections and colonization in older adults having bone and orthopedic surgery

Urinary Infection and Colonization in Bone Procedures

Observational Tomas Bata Hospital, Czech Republic · NCT06896643

This will see if having a urinary infection or colonization before bone or orthopedic surgery raises the risk of postoperative complications in people aged 65 and older.

What this trial studies

Older adults (65+) undergoing elective or acute bone, trauma, or orthopedic surgery will have routine pre-anesthetic urine testing (chemical + sediment) with bacteriology if indicated. Investigators will record symptoms, fever, whether the urinary finding was treated and whether a control urine test was done, patient origin (home or social care), Clinical Frailty Scale, type of anesthesia, and any antibiotics given. During hospitalization the team will monitor for postoperative urinary infection and predefined complications including fever, circulatory instability, delirium, sepsis, and death, and will track patients' ward trajectory and length of stay. The protocol is observational and does not alter standard clinical care.

Who should consider this trial

Good fit: Ideal candidates are patients aged 65 or older undergoing elective or acute trauma/orthopedic bone surgery at the enrolling hospital who receive standard pre-anesthetic urine testing and can provide informed consent.

Not a fit: Patients under 65, those with negative preoperative urine tests, and those excluded for acute severe conditions or impaired capacity (for example delirium, coma, severe mental disorder, or septic state) are unlikely to benefit from this study's findings.

Why it matters

Potential benefit: If a clear link is found, clinicians could better identify and manage preoperative bacteriuria to lower postoperative complication risk in older surgical patients.

How similar studies have performed: Previous research on the relationship between preoperative bacteriuria and postoperative complications is limited and mixed, with some specific surgeries showing associations but no consistent consensus.
