HL7 BPX Segment: Blood Product Dispense Status

Overview

The BPX (Blood Product Dispense Status) segment communicates the current dispense status of a blood product previously ordered with a BPO segment. One BPX is sent per dispensed blood product unit and travels inside a blood-product dispense status response (BRP) triggered by a BPS message. It carries the dispense status code, an overall status indicator, the date/time the status was assigned, donation identifiers, component coding, manufacturer and lot details, expiration data, quantity, and the receiver and dispensing personnel.

When to use BPX

Use BPX whenever the blood bank reports a change in the dispense lifecycle of a previously ordered blood product — for example, when a unit is reserved, released to the floor, returned, wasted, or finally issued. Each BPX repetition represents a single dispensable unit within the response.

Used in

BPX is reported inside the blood-product dispense status response (BRP) generated for a BPS blood-product dispense status message. One BPX appears per dispensed unit within the bb-products group, alongside the parent BPO.

In both responses BPX is paired one-to-one with the originating BPO repetition, so receivers can match the dispense status (BPX) back to the order (BPO) and forward to the transfusion event (BTX).

FHIR mapping

No segment-level ConceptMap is published in the v2-to-FHIR IG for BPX. The information conveyed by BPX maps conceptually to FHIR MedicationDispense (with medicationReference pointing at a BiologicallyDerivedProduct) and, for the in-flight clinical transfusion event, to MedicationAdministration. Donation identifiers (BPX-5) and component coding (BPX-6) align with BiologicallyDerivedProduct.identifier and productCategory.

Implementation notes

BPX-2 (HL70510) and BPX-3 (HL70511) are tightly linked: BPX-2 carries the granular dispense state, while BPX-3 carries the high-level transition signal (SC = status change, OK = OK, ER = error).
BPX-12 is the only repeating field — use the ~ repetition separator to convey multiple special testing attributes such as CMV-negative plus irradiated.
BPX-17 (BP Unique ID) is the local dispenser-assigned identifier; BPX-5 is the collection facility's donation ID. Keep both populated so transfusion services can reconcile against either identifier.
Each BPX must reference the same Set ID space as its parent BPO repetition inside the bb-products group.
