Single-dose Intravenous Iron Therapy for Anemia After Orthopaedic Trauma

August 4, 2025 updated by: Zachary Working, Oregon Health and Science University

Role of Single-dose Intravenous Iron Therapy for the Treatment of Anemia in the Setting of Orthopaedic Trauma: a Pilot Study

Acute blood loss in orthopaedic trauma and operative fracture care contributes substantially to perioperative anemia, which places participants at increased risk for complications including surgical site infection, cardiovascular complications, and even death. Anemia has further clinical implications in quality of life measures and is associated with fatigue, impaired physical performance, decreased exercise capacity, and mood disturbances. Thus, evaluation and treatment of perioperative anemia is critical in risk mitigation within orthopaedic surgery. The current standard of care for anemia is transfusion of packed red blood cells in only cases of severe anemia due to the substantial associated risks. A safer alternative is desirable because a critical number of participants do not meet the restrictive transfusion threshold and may suffer negative effects from anemia during recovery from the acute insult. The focus of this project is to pilot an investigation of the benefits of intravenous iron therapy (IVIT) in traumatically injured patients. Specifically, Aim I will determine feasibility of study design, recruitment, randomization, intervention implementation, blinded procedures, and retention. In Aim II, time to return to normal hemoglobin following traumatic orthopaedic injury will be assessed. With Aim III, the investigators will measure IVIT effect on participant-reported fatigue, physical function, and depression, and further determine if resolution of anemia is correlated to improvements in these measures in traumatically injured orthopaedic patients. Aim IV will focus on evaluating the role of IVIT on immune cells through a variety of novel laboratory assessments. The investigators expect this study to provide a better understanding of IVIT, which has the potential to alter providers' treatment approach of anemia in participants who sustain traumatic orthopaedic injury, thereby leading to decreased risks and improved recovery.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of participant enrollment and screen failures
Time Frame: 3 months
Appraisal of feasibility based on rate of participant enrollment per year and rate of screening failures.
3 months
Evaluation of protocol adherence
Time Frame: 3 months
Appraisal of feasibility based on proportion of participants completing each follow up visit and proportion of missing data.
3 months
Patient Reported Outcome Scores: Fatigue
Time Frame: 3 months
PROMIS bank v1.0 - fatigue. Computer adaptive test that measures feelings of tiredness likely to decrease one's ability to execute daily activities and function normally in family or social roles. Scored on the T-score metric (average score 50, standard deviation 10). High scores mean more of the concept being measured.
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rate of anemia and anemia resolution in participants
Time Frame: 3 months
Measured by the concentration of hemoglobin (oxygen carrying protein) in whole blood. This marker of anemia (defined as hemoglobin <12g/dL in females and <13.5g/dL in males) measured for inclusion assessment and to monitor for time to resolution of anemia at all study follow-up visits.
3 months
Evaluation of ferritin level in response to IVIT after trauma
Time Frame: 3 months
Evaluated at enrollment to assess for iron overload (patients with a ferritin level ≥ 1,000ng/mL will be excluded) and tracked throughout the study to measure participants' body stores of iron.
3 months
Evaluation of participant body iron stores in response to IVIT after trauma
Time Frame: 3 months
Assessment of body iron stores and iron carrying capacity within blood. Utilized to further define patients' anemia and iron available for functional use.
3 months
Patient Reported Outcome Scores - Depression
Time Frame: 3 months
PROMIS bank v1.0 - depression. Computer adaptive survey administered to assess negative mood, views of self, social cognition, and decreased social engagement. Scored on the T-score metric (average score 50, standard deviation 10). High scores mean more of the concept being measured.
3 months
Patient Reported Outcome Scores - Physical Function
Time Frame: 3 months
PROMIS bank v1.2 - physical function. Computer adaptive survey which measures self-reported capability to perform physical activities including activities of daily living. Scored on the T-score metric (average score 50, standard deviation 10). High scores mean more of the concept being measured.
3 months
Patient Reported Outcome Scores - Quality of Life
Time Frame: 3 months
EQ-5D-5L Quality of Life Questionnaire. Instrument assesses five dimensions of health, corresponding to 3,125 possible health states that can be converted into a single 'utility' score. This will be utilized for the assessment of quality-adjusted life years (QALYs) and cost effectiveness of IVIT for the treatment of acute blood loss anemia following surgical fracture stabilization. Scored from 0-100, 100 being the best health state and 0 being the worst.
