Summary
A new computerized blood order consultant system accurately recommended blood transfusions, agreeing with experts 95.5% of the time. This system may simplify ordering and reduce red blood cell (RBC) units used.
Area of Science:
- Medical Informatics
- Transfusion Medicine
- Health Systems Engineering
Background:
- Hospitals utilize computerized systems to optimize blood ordering and transfusion practices.
- Early systems, like the critiquing system at LDS Hospital, showed both benefits and limitations.
Purpose of the Study:
- To develop and evaluate a second-generation computerized blood ordering system using a consultation mode.
- To assess the accuracy and efficiency of this new system in recommending blood product orders.
Main Methods:
- A pilot test was conducted using historical data from the HELP Hospital Information System (HIS).
- The new blood order consultant system's recommendations were compared against expert (blood bank director) assessments.
Main Results:
- The consultant system demonstrated high accuracy, agreeing with expert recommendations for red blood cell (RBC) and platelet orders 95.5% of the time.
- The system recommended fewer RBC units for transfusion compared to standard practice.
Conclusions:
- The computerized blood order consultant system shows promise for simplifying blood ordering.
- Preliminary results suggest potential for reducing the overall number of blood products ordered.
