Study Details

Brief summary:

Perioperative neurocognitive disorders are common after surgery and pre-existing cognitive impairment is an important risk factor. Current guidelines recommend identifying cognitive impairment before surgery; however, screening remains inconsistent, particularly when preoperative assessments are performed remotely.

This prospective observational diagnostic validation study aims to determine whether a modified Mini-Cog cognitive screening tool administered by telephone can reliably identify cognitive impairment in patients aged 65 years and older undergoing preoperative assessment. Telephone-based modified Mini-Cog results will be compared with standard in-person Mini-Cog assessments to evaluate agreement and feasibility. This study may improve access to preoperative cognitive screening and support optimization of surgical care for older adults.

Interventions and Outcome Measures

Interventions

Modified Mini-Cog Telephone Assessment

A modified Mini-Cog cognitive screening assessment administered by telephone to evaluate its reliability and concordance with standard in-person Mini-Cog assessment in older adults undergoing preoperative assessment.
