The utility of remote cognitive screening tools in identifying cognitive impairment in older surgical patients: An observational cohort study
Authors' conclusion
The CDC cognitive question, AD8, TICS-M, and T-MoCA were easily implemented during preoperative assessment among older surgical patients. OSA, functional disability, and depression were associated with complaints on the CDC cognitive question and AD8. Older age, male sex, and higher pain level were associated with screening positive on the TICS-M and T-MoCA.
