Urinary Infection and Colonization in Bone Procedures

For seniors aged 65 and over (inclusive) undergoing surgical procedures (bone surgery, traumatology, orthopedics) in an acute or elective setting, the relationship between preoperative urinary tract infection/colonization (within 30 days before the procedure) and the occurrence of predefined postoperative complications (monitoring during the patients' hospitalization) will be observed

For seniors aged 65 and over (inclusive) undergoing surgical procedures (bone surgery, traumatology, orthopedics) in an acute or elective setting, the relationship between preoperative urinary tract infection/colonization (within 30 days before the procedure) and the occurrence of predefined postoperative complications (monitoring during the patients' hospitalization) will be observed Among the monitored parameters before the surgical procedure will be urine collection (chemical + sediment - a common part of the pre-anesthetic examination), and in case of findings, a sample for bacteriological examination will be indicated. Additionally, subjective symptoms (present, absent), presence of fever, whether the infection/finding in the urine was treated or not, and whether a control urine examination was performed (performed, not performed) will be recorded. The origin of the patient (home, social care facility) and the planned surgical procedure will be noted. The Clinical Frailty Scale, type of anesthesia (general, regional), and any administered antibiotic treatment will also be recorded.

After the surgical procedure, the occurrence of urinary infection (yes, no, sample not taken) will be assessed. Postoperative complications such as fever, circulatory instability, development of delirium, infection, septic state, and death will be monitored. The trajectory of the respondent during hospitalization (which departments they will be treated in, including the length of hospitalization) will be recorded. The primary goal will be to determine the relationship between the preoperative occurrence of urinary infection or colonization in patients within the last 30 days before the procedure and the occurrence of predefined postoperative complications. Secondary goals will include identifying the most common postoperative complications in patients with preoperative urinary colonization or proven urinary infection. Additionally, the relationship between the preoperative Clinical Frailty Scale in the defined patient population and the occurrence of predefined postoperative complications will be examined. The final secondary goal will be to determine preoperative antibiotic therapy in the preoperative period.

The cohort of traumatology patients undergoing surgical procedures was chosen to ensure the homogeneity of the studied population (seniors over 65 undergoing bone surgery).
