Factors associated with adverse outcome following urologic surgery in patients aged 80 years and older

摘要

Background and aims: This study was designed to find predictors for adverse post-operative outcomes in elderly patients aged 80 years and older, who underwent urologic surgery. Methods: In this prospective observational study, we analysed data, including age, gender, American Society of Anesthesiologists (ASA) class, co-morbidities, number of regular medications, type and extent of surgery, type of anesthesia, duration of surgery and hospitalization, post-operative morbidity and mortality. We studied the correlations between each pre- and intra-operative parameter to the consequence, to find predictors for adverse outcome. Results: During a 12-month period, 217 patients underwent 294 urologic procedures in our institution. Ninety-eight procedures (33 %) were followed by complications and 11 patients (5 %) died. Patients who had uneventful surgery and hospitalization were significantly younger than those who experienced morbidity or mortality. There was a significantly higher complication rate among patients with a higher ASA class or with ischemic heart disease, following higher graded or longer operations, and after emergency surgery. Conclusions: Older age is a significant risk factor. Patients with higher ASA class or ischemic heart disease are at higher risk for post-operative complications and thus, require careful follow-up. In this age population, extensive or prolonged surgery should be carefully considered.
