Blood Bank

import { Steps } from ‘@astrojs/starlight/components’;

The Blood Bank module covers the full transfusion chain: donor to inventory to immunohaematology to crossmatch to issue to bedside administration to haemovigilance. Two safety controls run through the whole module — the TTI release gate and the two-person bedside check — and both are enforced, not advisory. Every decision is signed with your eSign PIN (your 6-digit electronic signature, separate from your password).

Key terms: TTI is Transfusion-Transmitted Infection screening; ABO is the ABO blood-group system; ISBT is the International Society of Blood Transfusion coding standard; FEFO is First Expire, First Out — units are issued earliest expiry first; TACO and TRALI are transfusion reaction types.

Who uses it

• Blood-bank scientists register donors, screen donations, type and crossmatch, and run the issue desk.
• Ward nurses perform the bedside administration with a second checker.
• The module is gated through the Labs module’s permissions.

Editions

Available in Hospital and Network editions. (Blood Bank depends on the Labs module.)

Network Transfers	Move units between facilities in a network.

Register and screen a donor

1. Open Donors (the page is titled Donor Management). Press Register Donor and complete the donor record.

2. Record the donor’s screening on the donor record. The outcome can be Accepted or Deferred (temporarily, with a defer-until date, or permanently).

TTI screening — the release gate

Every donation is TTI-screened before any unit it yields can be transfused.

1. Open Immunohaematology and the TTI tab.

2. Press Record TTI Panel and enter the result for each marker: HIV, HBsAg, HCV, Syphilis, Malaria, and HTLV. Each marker is Reactive or Non-Reactive.

3. Press Sign Out on the panel and enter your eSign PIN.

Caution

A donation’s units only become Available when its TTI panel is signed out with every marker Non-Reactive. Until then the units sit in Quarantine. If any marker is Reactive, signing out quarantine-discards the donation’s units — they can never be issued. This gate is enforced server-side; it is the single most important safety rule in the module.

Typing and antibody screen

In Immunohaematology, the Typing tab records ABO/Rh blood-group typing and the Antibody tab records the recipient irregular-antibody (Coombs) screen. Each verdict is signed out with your eSign PIN through the same central signing layer.

Crossmatch

1. Open Crossmatch. The system pairs a request with a TTI-cleared candidate unit — only released units are eligible.

2. Record the result (Compatible or Incompatible) and sign it out with your eSign PIN.

3. A signed Compatible result reserves the unit (Available → Reserved), advances the request to Crossmatching, and notifies the requesting clinician. An Incompatible result signs the exclusion.

Reserve and issue a unit

Open the Issue Desk to reserve a compatible unit and then issue it. Issuing is an eSigned cold-chain checkout — the unit leaves the bank against a signed record.

Bedside two-person administration

1. At the bedside, open Administration (the page is titled Bedside Administration).

2. Add the Second Checker (Witness) — a second checker is required; the bedside check cannot proceed without one.

3. Confirm all three bedside checks: patient identity, unit identity, and compatibility. Record the pre-transfusion and timed vitals on the timeline.

Caution

The two-person check is mandatory. You must name a second checker (witness) and confirm the three identity-and-compatibility checks before administration can start, mirroring the controlled-drug witness control in the ward MAR.

Transfusion reactions

If a reaction occurs, record it in Reactions (the haemovigilance register), including the reaction type (such as TACO or TRALI) and severity. The register is the auditable haemovigilance trail.
