This is a prospective multicenter cohort study which will evaluate rapid (administration time ≤ 5 minutes) cognitive screening tools that can be administered preoperatively in older patients undergoing noncardiac surgery. Namely, our study will determine the diagnostic accuracy (sensitivity, specificity, and area under the curves \[AUC\]) of two rapid, easily administered cognitive screening tools: the Mini-Cog and the Ascertain Dementia 8-item Questionnaire (AD8) against the Montreal Cognitive Assessment (MoCA). Additionally, we will examine the prevalence of cognitive impairment (CI) in patients meeting the CI criteria by either the AD8, Mini-Cog, MoCA, or a single cognitive question from the Centers for Disease Control and Prevention \[CDC\]. This study will target older patients from surgical offices and/or pre-admission clinics at Toronto General (TGH), Toronto Western (TWH), and Mount Sinai Hospital (MSH), Toronto, Ontario. The identification and recruitment of eligible patients will be a collaborative effort between the nurses, surgeons, anesthesiologists, and the research team. Written informed consent to participate in the study will be obtained from all patients.
