Summary

A new blood volume policy for pediatric lab testing was developed, balancing patient hematological status with procedural costs. While smaller volumes are sometimes necessary, larger volumes may be more cost-effective and maintain lab service quality.

Area of Science:

  • Pediatric Hematology
  • Clinical Laboratory Science
  • Healthcare Policy

Background:

  • Pediatric cancer patients often require frequent blood draws due to treatment protocols and extended hospital stays.
  • Managing blood draw volumes is critical to prevent compromising pediatric patients' hematological status.
  • Concerns from nursing and laboratory staff regarding blood draw volumes were identified.

Purpose of the Study:

  • To develop a standardized blood volume policy for pediatric laboratory testing.
  • To address the challenges of frequent blood draws in pediatric cancer patients.
  • To balance patient safety with operational efficiency and cost-effectiveness.

Main Methods:

  • A multidisciplinary team collaborated to create the policy.

  • A three-tiered blood volume system was designed based on patient weight (<10 kg, <20 kg, and adult volumes).
  • Considerations included blood volume, cost, draw time, equipment, and order flexibility.

    • Main Results:

    • The tiered system aims to reduce blood volume for smaller patients.
    • Each successive tier (smaller volumes) incurs increased procedural costs.
    • Reduced blood volumes can lead to increased costs and potential decreases in laboratory service quality.

    Conclusions:

    • Discretion is essential when applying the blood volume guidelines to ensure quality of care.
    • Restricting blood volumes is important when medically indicated.
    • In non-medically necessary situations, the benefits of smaller volumes may be outweighed by increased costs and reduced lab service quality.
