18.8.22 BTX - Blood Product Transfusion/Disposition Segment (4.14.3)

HL7 Attribute Table - BTX - Blood Product Transfusion/Disposition

18.8.22.1 BTX field definitions (4.14.3.0)

The BP prefix in the element name indicates that the attribute pertains to any type of blood product. A blood product is defined as any type of blood component or commercially prepared blood product that is prepared and dispensed from the transfusion service.

The BC prefix in the element name indicates that the attribute pertains only to blood components. A blood component is defined as any part or all of a whole blood donation. For example, from one whole blood donation, the unit of whole blood can be fractionated into red blood cells, plasma and platelets with each component contained in separate bags. These types of blood products are always assigned a unique donation identification number as well as a product code that indicates the type of component contained in the bag.

The CP prefix in the element name indicates that the attribute pertains only to Commercial Products. A commercial product is defined as a commercially manufactured product, such as blood derivatives (Rh Immune Globulin, Factor VIII Concentrate or Blood Recipient Sets or Filters). These types of products are tracked by manufacturer and lot number and are not necessarily assigned a unique donation number.

18.8.22.12 BTX-11 BP Transfusion/Disposition Status (CWE) 01745 (4.14.3.11)

Definition: This field indicates the current status of the specified blood product as indicated by the placer. For example, the placer may return the blood product to the transfusion service unused because an IV could not be started. The blood component may have been entered, but the line was clogged and could not be used, in which case the component must be wasted. A final status would indicate that the product has actually been "transfused." Refer to HL7 Table 0513 - Blood Product Transfusion/Disposition Status in Chapter 2C, Code Tables, for suggested values.

18.8.22.13 BTX-12 BP Message Status (ID) 01746 (4.14.3.12)

Definition: The most commonly used message status values in a BTX will be preliminary and final. A status is considered preliminary until a blood product has reached a final disposition for the patient. For example, when the product is first cross-matched and a status message is sent, it would be considered preliminary. When the product is dispensed to the patient, that status would also be considered preliminary. However, once the product is transfused, the status would be considered final. The status of a blood product (BTX-11) can continue to change and the previous result should be overwritten until it reaches a final status (BTX-12). Refer to HL7 Table 0511 - BP Observation Status Codes Interpretation in Chapter 2C, Code Tables, for valid entries.
