ORACL: ORthopaedic Trauma Anemia With Conservative Versus Liberal Transfusion
Study Details
Study Description
Brief Summary
The purpose of this study is to determine if there is a difference in outcomes between liberal transfusion (transfusing when hemoglobin drops below a set higher value number) and conservative transfusion (transfusing when hemoglobin drops below a set lower value number).

Detailed Description
Transfusion of Orthopaedic trauma patients is routinely done in asymptomatic individuals as there is no accepted national standard or recommendations from the American Academy of Orthopaedic Surgeons or the Orthopaedic Trauma Association for what level of anemia is appropriate in an asymptomatic patient. Individual practitioners typically make this decision based on anecdotal experiences and expert opinion. No prospective study has been performed to date to answer this question in this patient population.
The null hypothesis of this proposed pilot study is that no difference will be seen with a liberal transfusion strategy to keep a patient's hemoglobin above 7 g/dL versus a conservative strategy to keep the patient's hemoglobin above 5.5 g/dL in patients asymptomatic at rest. The primary outcome of this pilot study will be infection; defined as postoperative wound infection (superficial or deep) or other perioperative infection but not surgical site (urinary tract infection or pneumonia). Deep infection is defined as the need for intravenous antibiotics or a return to surgery for debridement. Superficial infection is defined as the use of oral antibiotics only successfully treat a surgical site infection. Secondary outcomes will include pulmonary embolism, deep venous thrombosis, acute renal failure or insufficiency, nonunion, delayed union, compartment syndrome, osteomyelitis, nerve palsy, anoxic brain injury, cardiac ischemia or infarct, pancreatitis, or death, and the musculoskeletal functional assessment.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: Liberal Blood and blood products for transfusion. Transfusion will be done to keep Hgb >7 g/dL. |
Biological: Blood and blood products for transfusion
Randomization would not occur until the patient's Hgb dropped below 7 g/dL. If the patient is randomized to the liberal arm, they would be transfused to keep their Hgb >7 g/dL. If the patient is randomized to the conservative arm, they would not be transfused until their Hgb drops below 5.5 g/dL. If the patient's Hgb does not drop below 7.0 g/dL, randomization will not be done.

Outcome Measures
Primary Outcome Measures
- postoperative wound infection (superficial or deep) or other perioperative infection, information collected via subject questionnaire or record review [one year]
Secondary Outcome Measures
- Instances of Grade 3 Through Grade 5 Adverse Events Deemed Related to Transfusion, Graded According to NCI CTCAE Version 4.0, will be collected via subject questionnaire or record review [one year]
Complications to be reported: pulmonary embolism, deep venous thrombosis, acute renal failure/insufficiency, nonunion, delayed union, compartment syndrome, osteomyelitis, nerve palsy, anoxic brain injury, cardiac ischemia/infarct, pancreatitis, or death)
- musculoskeletal functional assessment questionnaire [one year]
A 101 item questionnaire to provide information on daily functioning
