The incidence of postoperative delirium in elderly patients undergoing urologic surgery
Abstract
Background & objectives: Postoperative delirium is a frequent disorder in sick and elderly patients and has been associated with extended hospital stay and increased cost. The purpose of this study was to assess its etiology and incidence and the effectiveness of routine screening of vague postoperative delirium in the elderly using Confusion Assessment Method (CAM). We aimed to evaluate the risk factors and strategies for prevention and treatment as well as the impact of this psychiatric disorder on postoperative morbidity and mortality. We also assessed the economic impact of this disorder.
Methodology: In this prospective, descriptive study, 640 patients, age 65 years or older, were included who underwent surgery at a urology clinic. All patients with a history of psychological problems and treated for these before admission were excluded from the study. Variables noted were: age, use of medications, signs and symptoms, biochemical and clinical balance, hemodynamic profile, and pre, intra and postoperative evaluation.
