O blood usage trends in the pediatric population 2015-2019: A multi-institutional analysis
Insights
Pediatric transfusions often use group O red blood cells even for non-O patients. This study identified key patient groups, like those with cardiovascular disorders and sickle cell anemia, receiving group O blood, offering insights for blood supply management.
Area of Science:
- Transfusion Medicine
- Pediatric Hematology
- Blood Banking
Background:
- Limited 2019 AABB recommendations on group O red blood cell use in pediatrics.
- Eight U.S. pediatric hospitals investigated trends in group O blood usage.
- Focus on identifying pediatric populations receiving group O blood despite non-group O blood type.
Purpose of the Study:
- To analyze pediatric transfusion practices regarding group O red blood cells.
- To clarify which pediatric patient groups receive group O blood transfusions when their blood type is non-O.
- To inform strategies for optimizing blood supply and transfusion safety in children.
Main Methods:
- Retrospective analysis of Electronic Health Records from eight pediatric institutions.
- Inclusion of data on unit and patient blood type, age, sex, and diagnosis.
- Utilized GPT-4 for diagnosis categorization and visualized data with alluvial plots, spaghetti plots, and stratified tables.
Main Results:
- 142,227 transfusion events analyzed; 52,731 recipients had non-O blood types.
- 67% of group O blood transfusions were given to A, B, or AB blood type recipients.
- Cardiovascular disorders (22%) and sickle cell anemia (15%) were top diagnostic categories for group O blood recipients.
Conclusions:
- Significant utilization of group O blood in non-O pediatric patients identified.
- Opportunities exist to safely use non-O blood in specific pediatric populations.
- Findings can help address challenges in maintaining an adequate group O red blood cell supply.
Background:
In 2019, AABB released the bulletin "Recommendations on the Use of Group O Red Blood Cells" in which the recommendations about pediatric and neonatal blood transfusions were limited. Eight U.S. pediatric hospitals sought to determine trends in pediatric group O blood use and clarify which pediatric populations receive group O blood transfusions despite a non-group O blood type.
Study Design And Methods:
Eight U.S.-based institutions serving a pediatric population provided data from their respective Electronic Health Records. Data submitted included unit blood type, patient blood type, patient age, sex, and discharge diagnosis. If the discharge diagnosis was not available, the admitting diagnosis was substituted. GPT-4 was used to sort diagnoses into categories for analysis. Data were visualized using a series of alluvial plots, spaghetti plots, and tables. Tables were stratified on variables of interest (blood type, age, sex, diagnosis) to explore O blood type distribution among different patient populations.
Results:
A total of 142,227 discrete transfusion events were identified, of which 52,731 recipients were non-O blood type. Overall, 35,575 transfusion events of O blood went to A, B, or AB blood type recipients (67%). Additionally, 26% of Rh(D) negative transfusion events went to recipients who were Rh(D) positive. Top diagnostic categories for receiving O blood type were cardiovascular disorders (22%) and sickle cell anemia (15%).
Discussion:
This study highlights opportunities to address O blood supply challenges by identifying where non-O blood may be utilized safely in the vulnerable pediatric population.
