Using evidence-based techniques to modify anemia screening practice.

Area of Science:

• Pediatrics
• Hematology
• Public Health

Background:

• Routine screening for iron-deficiency anemia in adolescents is a widespread clinical practice.
• The efficacy and necessity of universal screening in this demographic remain debated and unproven by robust evidence.

Purpose of the Study:

• To reevaluate a clinic's policy of mandatory complete blood counts (CBCs) for anemia screening in all new adolescent patients.
• To assess the yield of universal anemia screening in adolescents using evidence-based quality improvement methods.

Main Methods:

• Literature synthesis and review of national recommendations regarding adolescent anemia screening.
• Retrospective review of medical records for 229 new adolescent patients undergoing anemia screening via CBC.
• Analysis of clinic-specific data to determine the prevalence of unsuspected anemia.

Main Results:

• Clinically unsuspected iron-deficiency anemia was identified in 8 (3.5%) of 229 screened adolescents.
• All identified cases of anemia were mild, with only two patients requiring iron therapy.
• Following data review and consideration of national guidelines, the clinic reversed its policy of universal screening for new adolescent patients.

Conclusions:

• Universal screening for iron-deficiency anemia in adolescents via CBC may not be an effective use of resources, given the low yield of mild cases.
• Evidence-based quality improvement initiatives can inform and revise clinical policies to align with current recommendations and patient needs.
• Policy changes based on clinic-specific data and national guidelines significantly reduced the rate of CBC utilization for adolescent anemia screening.
