Long-FRI
R
Roman Natoli, MD
Primary Investigator
Overview
The overall aim of this proposal is to identify a biomarker diagnostic strategy that can be implemented in patients sustaining fractures at high-risk for infection. This proposal will address the hypothesis that there is a biomarker signature that will be able to discriminate between patients who develop FRI compared to matched controls.
Description
Venous blood samples will be obtained at four time points (T1-T4) that are otherwise part of routine standard of care follow-up for patient after fracture repair. The blood sample collections will be after definitive surgery for the injury which the patient is enrolled and prior to hospital discharge (T1), and postoperatively at 2-4 weeks (T2), 6-8 weeks (T3) and 3-4 months (T4). All four blood draws consist of a PAXgene RNA blood tube (2.5ml of blood), one 10mL EDTA blood tube, a 6ml red top serum tube, and an 8.5ml CPT tube for a total of 27ml per draw.
