Comparing dual and single antibiotic cement for hip surgery in elderly patients

DAICY Trial - Dual vs. Single-Antibiotic Impregnated Cement in Hemiarthroplasty for Femoral Neck Fracture: A Register-based Cluster-randomized Cross-over Controlled Trial

Phase 3 Interventional Umeå University · NCT05164081

This study is testing whether using a dual-antibiotic cement during hip surgery can help older patients avoid infections better than using a single-antibiotic cement.

What this trial studies

This clinical trial investigates the effectiveness of dual-antibiotic impregnated cement versus single-antibiotic cement in reducing the risk of periprosthetic joint infection (PJI) following hemiarthroplasty for displaced femoral neck fractures in elderly patients. The study aims to determine the incidence of PJI within one year post-surgery, alongside secondary outcomes such as re-operation rates, bacteriology, and healthcare costs. Conducted in Sweden, the trial addresses a significant health issue affecting a large population of frail elderly individuals, with a focus on improving surgical outcomes and reducing complications.

Who should consider this trial

Good fit: Ideal candidates for this study are elderly patients aged 60 and above with a displaced femoral neck fracture eligible for hemiarthroplasty.

Not a fit: Patients with previous hip surgeries, pathological fractures, or sensitivities to the components of the bone cement may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly lower the incidence of infections following hip surgeries, improving recovery and quality of life for elderly patients.

How similar studies have performed: Other studies have shown promising results with antibiotic-impregnated cement in reducing infection rates, suggesting this approach may be effective.
