Don’t perform laboratory blood testing unless clinically indicated so that the risk of iatrogenic anemia is minimized.
Up to 90% of patients become anemic by day 3 in the intensive care unit. Although laboratory testing can aid in diagnosis, prognosis and treatment of disease, a significant number of tests are inappropriate or unnecessary. Anemia secondary to iatrogenic blood loss causes an increased length of stay and increases the odds for transfusion and its associated risks. Unnecessary laboratory testing adds to the cost of care through laboratory test charges and also by increasing downstream costs due to unnecessary interventions, prescriptions, etc. Thus judicious use of laboratory testing is recommended, and testing should not be performed in the absence of clinical indications.

The Executive Committee and Board of Directors (BOD) of the Society for the Advancement of Patient Blood Management (SABM) had a strong desire to participate in the Choosing Wisely campaign. Participation allows SABM to align with the national Choosing Wisely® team and other specialty societies to further the mission of collaborative physician-patient health care delivery and responsible use of resources.
A Task Force was appointed from within the BOD to draft the initial set of recommendations. Evidence-based recommendations were based on our society’s foundational pillars and structured around published SABM Standards. A critical feature was the review of relevant literature for supporting evidence applicable to each statement. Ultimately, the draft recommendations were submitted to the membership for input via an email survey. This resulted in the final five statements for which evidentiary materials and pertinent references were written. The BOD approved the materials prior to submission. Recent review with updates was undertaken by the SABM Educational Oversight Committee.
Working with this initiative, our selected recommendations and integrated materials were further honed based on subsequent campaign review. This list and supporting material resulted in a publication in a peer-reviewed journal in 2019. SABM will also develop monitors to assess the impact of the initiative for our members and hospital affiliates. We foresee this as a vehicle for outreach to other professional societies, health care providers and patients.
