Hospital-acquired anemia (HAA) is a prevalent condition that is independently associated with worse clinical outcomes including prolongation of hospital stay and increased morbidity and mortality. While multifactorial in general, iatrogenic blood loss has been long recognized as one of the key contributing factors to development and worsening of HAA during hospital stay. Patients can be losing over 50 mL of blood per day to diagnostic blood draws. Strategies such as elimination of unnecessary laboratory tests that are not likely to alter the course of management, use of pediatric-size or small-volume tubes for blood collection to reduce phlebotomy volumes and avoid blood wastage, use of closed blood sampling devices, and substituting invasive tests with point-of-care testing alone or bundled together have generally been shown to be effective in reducing the volume of iatrogenic blood loss, hemoglobin decline, and blood transfusions, with no negative impact on the availability of test results for the clinical team. These strategies are important components of Patient Blood Management programs and their adoption can lead to improved clinical outcomes for patients.
