This is a prospective multicenter cohort study, which will determine the prevalence of preoperative cognitive impairment (CI) using the Modified Telephone Interview for Cognitive Status (TICS-M), Eight-items interview to Differentiate Aging and Dementia (AD8), Telephone Montreal Cognitive Assessment (T-MoCA), and a single cognitive question from the Centers for Disease Control and Prevention (CDC). We would also determine the (1) the degree of agreement in screening results between each cognitive screening tool, (2) risk factors associated with screening positive for CI on each tool, and (3) the prevalence and/or trajectory of postoperative delirium, sleep disturbances, functional disability, instrumental activities of daily living (IADL), depression, quality of health, frailty, and pain in older surgical patients and its association with CI. This study will target older patients from the pre-operative clinics at Toronto Western Hospital and Mount Sinai Hospital (MSH), Toronto. Research staff will identify eligible patients who are scheduled for elective non-cardiac surgery. Written informed consent to participate in the study will be obtained from all patients.
