What this trial studies

This observational study aims to assess the relationship between poor sleep health and the quality of recovery in patients undergoing elective lower limb joint replacement surgeries. It will evaluate pre-operative sleep health parameters and their association with patient-centered outcomes such as pain control and delirium. The study will utilize various sleep health measurements to understand how sleep disturbances affect recovery and overall health outcomes in a surgical setting.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients over 18 years old undergoing elective primary or revision lower limb joint replacement surgeries.

Not a fit: Patients undergoing emergency surgeries or those with specific exclusions such as pregnancy or inability to comply with monitoring requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery outcomes for surgical patients by optimizing their sleep health.

How similar studies have performed: Other studies have shown promising results in improving recovery outcomes through better management of sleep health, indicating that this approach has potential.
