BPX - Blood Product Dispense Status Segment

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.

BPX-1: Set ID – BPX (SI) 01714

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.

BPX-2: BP Dispense Status (CWE) 01715

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.

BPX-3: BP Status (ID) 01716

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.

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

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.

BPX-5: BC Donation ID (EI) 01718

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.

BPX-6: BC Component (CNE) 01719

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.

BPX-7: BC Donation Type / Intended Use (CNE) 01720

Definition: This field indicates the type of donation or collection/intended use. This value is populated from Table 5 -Type of Donation in the ISBT 128 Application Specification. The default value is "0", meaning "Not specified." Other values indicate whether the blood product (1) is an allogeneic unit from a volunteer donor, (2) is intended for a specific recipient but may be crossed over and used for another recipient, or (3) is an autologous donation intended only for that particular recipient. Refer to Table 0578 - BC Donation Type / Intended Use in Chapter 2C for valid values.

This field is optional for blood component messages and is not applicable for commercial product messages.

BPX-8: CP Commercial Product (CWE) 01721

Definition: This field contains the code and/or text to identify a commercial product. Examples of commercial products are blood derivatives such as Rh Immune Globulin and Factor VIII concentrate, Leukoreduction filters, and blood administration sets. Refer to Table 0579 - BP Blood Group in Chapter 2C for valid values.

Either code and/or text may be absent. However, the code is always placed in the first component position and any free text in the second component. Thus, a component delimiter must precede free text without a code. Free text can be utilized if no update is to occur. Refer To User-Defined Table 0512 - Commercial Product in Chapter 2C, Code Tables, for suggested values.

This field is required for commercial blood products and is not applicable for blood component messages.

BPX-9: CP Manufacturer (XON) 01722

Definition: This field identifies the manufacturer of the commercial product. The manufacturer may be different from the supplier of the commercial product.

This field is required for commercial blood products and is not applicable for blood component messages.

BPX-10: CP Lot Number (EI) 01723

Definition: This field identifies the lot number for blood derivatives or commercially supplied items used as accessories to transfusion.

This field is required for commercial blood products and is not applicable for blood component messages.

BPX-11: BP Blood Group (CNE) 01724

Definition: This field indicates the ABO/Rh blood group of the blood component. The preferred values for the blood group are the specified values in Table 3A - Encodation of ABO/Rh Blood Group in the ISBT 128 Application Specification. Refer to Table 0579 - BP Blood Group in Chapter 2C for valid values.

This field is required for blood components and certain commercial products (such as solvent detergent plasma).

BPX-12: BC Special Testing (CNE) 01725

Definition: This is a repeating field to allow multiple entries for special testing that was performed on the blood component. The preferred coding system for Special Testing is defined in the ISBT 128 Application Specification. Proposals have been developed and will soon be published by ICCBBA, Inc. for the encodation of other antigen and antibody specificities, including HLA, platelet, red cell and other types of markers. Refer to Table 0580 - BC Special Testing in Chapter 2C for valid values.

This field is optional for blood component messages. It is not applicable for non-commercial product messages.

Refer to Table I3 - Special Testing Codes of the ISBT 128 Application Specification.

BPX-13: BP Expiration Date/Time (DTM) 01726

Definition: This field specifies the date and time that the blood product expires. The blood product is no longer considered acceptable once the expiration date has been reached unless cleared by the transfusion service medical staff.

This field applies to blood components as well as commercial products. There are a few commercial products that have no expiration date. Therefore, the field is not required for those specific products.
