NCT06052397

Brief Summary

The goal of this prospective cohort study is to assess potential differences in sleep biomarkers in older adult patients undergoing major orthopedic surgery. The main questions it aims to answer are:

  1. 1.To define sleep/circadian biomarkers of delirium (sleep duration, regularity, stability and timing of rhythm) in a prospective observational study.
  2. 2.To determine if plasma Alzheimer's disease (AD) pathology/inflammatory burden interacts with or moderates the relationship between a sleep/circadian biomarker and post-operative delirium (POD) risk.
  3. 3.To determine whether sleep/circadian regulation interacts with the genetic risk of AD to influence POD/cognitive decline.
  4. 4.Donate several blood samples both intraoperatively and postoperatively
  5. 5.Complete baseline and postoperative neurocognitive assessments
  6. 6.Wear an actigraphy data collection watch for the two weeks prior to their surgery

    From postoperative day 1 to postoperative day 3

  • Delirium-free Days

    Up until postoperative day 3, or up until postoperative day 7 or discharge for patients who are delirious beyond postoperative day 5

  • Postoperative Cognitive Status

    Months 1, 3, and 12 after surgery

  • Postoperative Insomnia Symptom Severity

    Baseline and months 1, 3, and 12 after surgery

  • Postoperative Sleep Quality

    Baseline and months 1, 3, and 12 after surgery

  • +10 more secondary outcomes

Other Outcomes (1)

  • Length of Hospital Stay

    Date of hospital admission up until date of discharge, assessed up to 30 days

Study Arms (1)

Sleep and Circadian Rhythms biomarker cohort

Cohort will complete a series of blood sample donations (both intraoperatively and postoperatively) as well as complete daily neurocognitive assessments at baseline and on PODs 1 - 3.
