18.8.20 BPX - Blood Product Dispense Status Segment (4.14.2)

In the processing of blood products, it is necessary for the transfusion service and the placer system to communicate information. The status messages need to contain additional information regarding the blood products requested, such as the unique donation ID, product code, blood type, expiration date/time of the blood product, and current status of the product. This segment is similar to an OBX segment, but contains additional attributes.

HL7 Attribute Table - BPX - Blood product dispense status

18.8.20.1 BPX field definitions (4.14.2.0)

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 the whole or any part of a 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 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.

18.8.20.2 BPX-1 Set ID – BPX (SI) 01714 (4.14.2.1)

Definition: This field contains the sequence number for the BPX segment under the related BPO segment. For the first blood product dispense status transmitted, the sequence number shall be 1; for the second product dispense status, it shall be 2; and so on.

18.8.20.3 BPX-2 BP Dispense Status (CWE) 01715 (4.14.2.2)

Definition: This field indicates the current status of the specified blood product as indicated by the filler or placer. For example, the first status change of a product that may trigger a Blood Product Dispense Status Message occurs when it first becomes linked to a patient and is ready to dispense. The placer system may use the Blood Product Dispense Status Message to request the transfusion service to dispense the product. When the blood product is delivered or issued to a patient, the status of the blood product would be changed to indicate that it has now been "dispensed." Refer to HL7 Table 0510 - Blood Product Dispense Status in Chapter 2C, Code Tables, for valid entries.

18.8.20.4 BPX-3 BP Status (ID) 01716 (4.14.2.3)

Definition: The most commonly used message status values in a BPX 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 (BPX-2) can continue to change and the previous status should be overwritten until it reaches a final status (BPX-3). Refer to HL7 Table 0511 - BP Observation Status Codes Interpretation in Chapter 2C, Code Tables, for valid entries.

18.8.20.5 BPX-4 BP Date/Time of Status (DTM) 01717 (4.14.2.4)

Definition: This field indicates the date and time that the status of the blood component was changed. For example, if the blood component had a status, of "RD" (Ready to Dispense), the date and time in this field would indicate the date and time that component was made ready to dispense by the filler system.

18.8.20.6 BPX-5 BC Donation ID (EI) 01718 (4.14.2.5)

Definition: The Donation ID is the unique identification number assigned to a blood donation. The Donation ID depends upon the bar code labeling system used for the component. There are currently two blood component labeling standards: ABC CODABAR and ISBT 128. The preferred labeling system is ISBT 128. If using ISBT 128, the Donation ID is an internationally unique identifier consisting of the following 13 characters:

Country Code & Collection Facility - 5 characters

Donation Year - 2 characters

Serial Number - 6 characters

This field is required for blood components and is not applicable for commercial product messages.

18.8.20.7 BPX-6 BC Component (CNE) 01719 (4.14.2.6)

Definition: The Component field includes an identifier and description of the specific blood component. Refer to Table 0577 - BC Component in Chapter 2C for valid values.

The identifier consists of a numeric or alphanumeric product code that represents the type of blood component. The coding system will be determined by the bar code labeling system on the particular component of blood. The preferred coding system is ISBT 128.

If using ISBT 128 labeling standard, the product code will consist of an 8-character alphanumeric code, starting with an alpha character and including the component class, donation type/intended use and division indicator.

If using CODABAR product labeling standard, the product code is a 5-digit number.

This field is required for blood components and is not applicable for commercial product messages.
