Perioperative medicine & outcomes
Prospective comparison of three methods for detecting peri‐operative neurocognitive disorders in older adults undergoing cardiac and non‐cardiac surgery
An erratum to this article was published (Anaesthesia, Sep 2024 ↗)
Authors' conclusion
There seems to be little to no pre-operative, postoperative or pre- to postoperative correlation between these tests and the neuropsychological assessment in older adults without pre-operative cognitive impairment.
Study context
- Population
- Elective surgical patients aged ≥ 65 years (cardiac and non-cardiac surgery), recruited September 2019–January 202128 (27%) lost to follow-up

- Outcome
- Correlation of tests with cognitive domain scores
