PREsurgical Cognitive Evaluation Via Digital clockfacEdrawing

This study leverages a modernized digital version of a well-known cognitive screening tool to examine pre and post operative cognitive function after surgery in adults age 65 years or more. Machine learning algorithms will be applied to the hospital wide standard of care cognitive metric to identify risk for post-operative cognitive complications.

About this study

This proposal innovatively leverages a brief but informative digital test with machine learning to examine the subtlety of pre-surgery cognition within an extremely large number of older individuals screened preoperatively within an academic tertiary medical center. It also incorporates a unique group of well characterized non-surgery peers for demographic matching to assist with normal versus abnormal machine learning analyses.

Treatment and study plan

digital cognitive testing

Behavioral

The digital testing is hypothesized to identify latent features for differentiating cognitively impaired presurgical patient subgroups

Primary outcomes

  1. Control and pre-surgery differences between digital behaviors

    Time frame: up to one year

    Measure range of digital outcome differences

Secondary outcomes

  1. Predictive validity of digital behaviors on outcome

    Time frame: up to 1 year

    Digital tools will predict clinician reported events

  2. Change over time in digital behavior between groups

    Time frame: up to 6-weeks

    Surgery group and control group differences from baseline to 6-weeks

  3. Change over time in digital behavior between groups

    Time frame: up to 3-months

    Surgery group and control group differences from baseline to 3-months

  4. Change over time in digital behavior between groups

    Time frame: up to one year

    Surgery group and control group differences from baseline to one year
