What this trial studies

The ORTOPOD Pilot Study is an observational study focusing on the relationship between preoperative cognitive function and the incidence of postoperative delirium in patients undergoing elective total hip arthroplasty. Participants aged 65 and older will be assessed for cognitive decline using the ALBA and POBAV tests, as well as evaluated for functional capacity and depression. Following surgery, patients will be monitored for signs of postoperative delirium using the CAM-ICU tool. The study aims to gather baseline data to understand the impact of cognitive dysfunction on postoperative outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 65 and older scheduled for elective total hip arthroplasty.

Not a fit: Patients with significant cognitive impairment, psychiatric illnesses, or those undergoing re-operation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for preventing postoperative delirium in elderly patients undergoing hip replacement surgery.

How similar studies have performed: Other studies have explored cognitive function and postoperative outcomes, suggesting potential benefits, but this specific approach is relatively novel.
