Preoperative evaluation of the elderly surgical patient

Family physicians are often requested to provide preoperative evaluation of elderly patients. Age independently increases the risk of morbidity and mortality in the perioperative period. In addition, the altered physiology of the older patient, in combination with the increased number of disease processes, increases the potential for complications. A comprehensive preoperative assessment includes an evaluation of the patient's present physiological functioning and attempts to detect the presence and status of any disease processes. Evaluation includes a thorough history, physical examination, and laboratory testing. Special considerations in preoperative assessment of the elderly patient include the assessment of nutrition, functional capabilities, and evaluation of the cognitive and emotional status of the patient. Special concerns include prophylaxis for deep vein thrombosis and pulmonary embolus, and antibiotic prophylaxis for endocarditis and for patients with joint prostheses.
