Study Notes
Iatrogenic Anemia Risk Factors
- Older adult patients, pediatric patients, and underweight patients are most susceptible to phlebotomy-induced iatrogenic anemia.
- Older adult patients are at higher risk due to medications that can suppress bone marrow production, decreasing nutritional intake, and experiencing extreme weight loss.
- Cancer patients are at higher risk due to cancer treatments and the disease's effect on the body.
Blood Volume Calculation for Infants
- Calculate infant blood volume by converting weight from pounds to kilograms.
- Divide pounds by 2.2 to convert to kilograms.
Blood Specimen Collection Guidelines
- Limit blood specimen collection to 1% to 5% of total blood volume within a 24-hour period.
- Limit blood specimen collection to 10% of total blood volume over an 8-week period for pediatric or critically ill patients.
Preventing Iatrogenic Anemia
- Communicate concerns with healthcare professionals if a venipuncture request seems excessive.
- Check with the nurse or provider to ensure the patient will not be put at risk.
- Contact the provider if the medical requisition requires blood tests that will collect more than the recommended amount.
- The provider can order different tests, reduce the number of tests, or order only the most essential tests.
