Iatrogenic anemia in hospitalized patients, not an uncommon occurrence, has been traced in studies to the amount of blood drawn over time.
Other studies suggest that blood loss from invasive blood draws induce iatrogenic anemia, with over 90% of intensive care unit (ICU) patients becoming anemic by the third day of ICU admission.
To prevent iatrogenic anemia from frequent blood draws, preanalytical as well as analytical systems should be capable of handling small sample volumes collected in pediatric tubes (2).
The need for repeated attempts to collect blood also increases the risk of iatrogenic anemia in patients, as well as risk of transmission of bloodborne pathogens to nurses and phlebotomists.
Proper blood-draw volume on infants is usually determined at the institutional level using a weight-based equation to ensure that iatrogenic anemia does not occur.
Another critical care complication has developed -- iatrogenic anemia.
Therefore, iatrogenic anemia due to lab testing is a constant threat.
If severe enough, iatrogenic anemia may require a blood transfusion.
What, if anything, has been and can be done to prevent iatrogenic anemia due to frequent lab testing?
Sherry Woodhouse's article on iatrogenic anemia is another well-written piece about a topic often overlooked in hospitals.
Iatrogenic anemia occurs when too much blood has been collected from a patient, causing additional medical problems.
As a result, we found our results are insensitive to change in many key areas, such as test cost, number of blood analyses performed, and factors associated with VAs, cardiac arrest, and iatrogenic anemia.
