Individuals with mild cognitive impairment have detectable deficits in one or more cognitive domain on testing and will usually have noticed (or their family noticed) a change in their memory, thinking or function. 🧠

Some will go on to develop dementia.
We included studies that used a cogntive assessment tool in people with vascular surgery disease (e.g. #PAD #AAA) that was symptomatic or >threshold for surgery (ie those that may be offered vascular intervention)

We made A LOT of data requests - thanks to those that replied! 🙌
The calculated prevalence varied greatly (lots of heterogeneity of studies)

In the limited meta-analyses the pooled prevalence of #CognitiveImpairment using the #MoCA of patients undergoing vascular surgery was 61% (95%CI 48% - 71%)!
This is likely to be an UNDER-estimate of all those considered for vascular surgery. Patients with cognitive impairment are less likely to be involved in research and these studies did not include patients managed conservatively.
This isn't a surprise...

The pathophysiology of #CognitiveImpairment is complex and heterogeneous but there's often and underlying vascular component and it's strongly associated with cardiovascular disease.
Why does it matter?🤷

Patients with worse cognitive function are more likely to have post-operative delirium.

Also under-recognised but a bad post-op complication associated with worse mortality and loss of independence.
We recommend pre-op cognitive screening in this paper

We do ECGs, Echos and cardiac stress tests to check 🫀 function

We do CXRs and spirometry to check 🫁 function

We do CPEX 🏃‍♀️🏃‍♂️ to check fitness

Why not also check 🧠 function?

Lots of cognitive screening tools available
But if we find #CognitiveImpairment what could we do about it?

1. Refer to a memory clinic
2. Consider deprescibing (⬇️ unecessary💊)
3. Consider operative strategy (limited evidence avoiding GA and endovascular interventions may have ⬇️ risk of delirium)
A huge thanks to my co-authors who did a lot of work towards this! 👏👏👏
