The impact of preoperative cognitive screening on postoperative outcomes in elderly surgical patients. Cognitive impairment is common in elderly patients, and surgery can exacerbate this condition. Preoperative cognitive screening has been suggested as a means of identifying paients at risk of postoperative cognitive dysfunction (POCD). This study analyzes the existing literature to examine the effects of preoperative cognitive screening on postoperative outcomes in elderly surgical patients. The study found that preoperative cognitive screening can identify patients at risk of POCD and can be used to optimize perioperative care to reduce the incidence of this condition. Cognitive dysfunction is a significant concern for elderly surgical patients. Postoperative cognitive dysfunction (POCD) is a common complication of surgery, with a reported incidence of up to 50% in elderly patients. POCD can result in decreased quality of life, increased morbidity and mortality, and increased healthcare costs. Several factors contribute to the development of POCD, including anesthesia, surgery, and patient-related factors such as age, comorbidities, and preexisting cognitive impairment.
