Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients aged 65 years and older who are scheduled for surgery due to femoral neck or intertrochanteric fractures.
✕Probably not a fit
Patients with preoperative delirium, dementia, or other significant comorbidities may not benefit from this study.

What this trial studies
This observational study aims to assess the effectiveness of the CRP-Albumin-Lymphocyte (CALLY) Index in predicting postoperative delirium (POD) in geriatric patients undergoing hip fracture surgery. It focuses on patients aged 65 and older, monitoring various biomarkers associated with delirium. The study will utilize the DSM-5 criteria for diagnosing delirium and will screen patients daily for signs of POD following their surgical procedures. The findings could help identify at-risk patients and improve postoperative care.
Why it matters
Potential benefit: If successful, this study could lead to better prediction and management of postoperative delirium, potentially reducing hospital stays and improving outcomes for elderly patients.
How similar studies have gone: While the approach of using biomarkers for predicting POD is gaining interest, the specific use of the CALLY Index in this context is relatively novel and has not been extensively tested in prior studies.
