Filter by: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, or MoCA and the prevalence of elevated levels of plasma biomarker of phosphorylated tau 181 (pTau181) and neurofilament-light chain (NfL) in the patients meeting the CI criteria. 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.
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 determine the (1) the diagnostic accuracy (sensitivity, specificity, and area under the curve (AUC)) of the AD8, CDC single cognitive question, and T-MoCA against the TICS-M and (2) the correlation between CI and measures of postoperative delirium, sleep disturbances, functional disability, instrumental activities of daily living (IADL), depression, quality of health, frailty, and pain in older surgical patients. 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.
