Blood bank EHR integration that eliminates manual data entry
Hospital systems and blood bank systems that don't talk to each other. Orders keyed in by hand, results keyed back. Duplicated data and the errors that follow. BloodBank.software integrates with Epic, Cerner, and other hospital systems, so orders flow in and results flow back on their own.
What it is
Two systems, one source of truth
Blood bank EHR integration means connecting your blood bank system directly to the hospital's electronic health record, so data moves both ways: orders placed in the hospital system reach the blood bank automatically, and results flow back for the physician to see. No manual entry, no duplicate record-keeping.
Most hospitals run the two separately. A physician orders blood; someone reads that and types it into the blood bank system. Tests complete; someone types the results back into the EHR. The same information now lives in two places, and mistakes happen wherever they disagree. Traditionally, closing that gap takes months and costs hundreds of thousands.
BloodBank.software has REST APIs built for this. Connect to virtually any hospital system, orders and results flow on their own, and integration is measured in weeks rather than quarters.
A physician orders O+ blood in Epic for a patient in theatre. The order arrives in BloodBank.software immediately and staff see it without anyone re-typing anything. The system suggests compatible units, staff allocate one, and Epic shows the blood is ready. Crossmatch passed, haematocrit normal — those results flow back into the patient chart automatically. The physician sees everything where they already work.
Why it matters
Six things that go wrong when the systems don't talk
Four of these are the daily cost of the gap. The fifth is why nobody closes it, and the sixth is what the physician experiences as a result.
Hospital and blood bank systems don't talk
The blood bank runs on one system and the hospital on another, with nothing between them. Orders are submitted by hand and results entered by hand — two systems, duplicated data, no integration.
Manual order entry creates delays
A physician orders blood in the EHR and someone has to read it and re-enter it in the blood bank system. That's 15 to 30 minutes during which a patient waits and surgery is held up, for a step that shouldn't exist.
Manual result entry creates errors
Crossmatch and testing complete, and someone types the results into the EHR. Numbers get transposed, units confused, tests recorded in one system but not the other — and the physician doesn't see the full picture.
Data duplication and inconsistency
The same information sits in both systems. The blood bank says the unit was issued at 2:30; the EHR says 3:00. Which is right? Whenever two records disagree, someone eventually acts on the wrong one.
Traditional integration is expensive
Connecting a blood bank to a hospital EHR has meant hiring integration consultants, six to twelve months of work, $250K to $500K or more, complex HL7 mappings, and maintenance costs that never end.
No real-time visibility
A physician orders blood and then has no idea when it will be ready. Crossmatch results aren't visible as they happen. The only way to find out is to phone the blood bank and ask.
How it's solved
Seven answers to those six problems
The first four describe what flows and in which direction. The last three are about meeting your hospital system where it already is, whatever it runs.
REST API integration
Complete REST APIs for hospital system integration, connected with standard calls rather than complex HL7 mappings. Documentation is included, because an API nobody can read isn't an integration path.
Developer documentationAutomated order flow
An order placed in the hospital EHR arrives in BloodBank.software immediately, with full details — patient, blood type, urgency, clinical indication. Staff see the order rather than a transcription of it.
Real-time unit allocation
When staff allocate a unit, the status updates in the hospital EHR straight away and the physician sees that the blood is ready. Nobody phones the blood bank to ask.
Automatic result flow
Crossmatch and testing results flow back into the hospital EHR as they complete, appearing in the patient chart without re-entry — complete information where the physician actually works.
Bidirectional communication
Orders in, results out, status updates in real time. Both systems stay synchronised, which is what makes "one source of truth" a description rather than an aspiration.
HL7 and FHIR support
Both HL7 v2 and FHIR are supported, so a hospital system on either standard can integrate. Nothing here depends on a proprietary format only we understand.
Custom API endpoints
For hospital systems without standard integration, custom endpoints are available. Your integration team builds what's needed; we provide the infrastructure and the data access.
Results
What changes once the two systems are connected
Seven outcomes hospitals report after integrating their EHR with the blood bank.
From kickoff to go-live
Against six to twelve months for a traditional integration project. Your integration team plus our API support — quick, clean, and finished.
Measured
Average integration project runs 2–4 weeks from kickoff to go-live.
Saved on consulting fees
Traditional EHR integration means consultants at $250K to $500K and up. With documented REST APIs, your own team handles it and the saving lands immediately.
Manual data entry between systems
Orders, results, and status updates all flow automatically. With no manual entry points there are no transcription errors, which is a stronger guarantee than being careful.
Order visibility, with no entry delay
Blood bank staff see the order the moment it's placed, allocation happens immediately, and status flows back in real time. That matters most on the urgent transfusions.
Status at every stage
Order received, testing in progress, unit ready, unit transfused — the physician can see where things stand without ringing anyone. No mystery in the middle of the workflow.
Source of truth
No duplicate data across two systems and no inconsistencies to reconcile. Unified information is a patient safety improvement before it is a convenience.
For every additional location
Once one system is integrated, adding hospital locations is the same API against a different instance — a model that scales rather than a project you run again from scratch.
We thought EHR integration would take six months and cost $500K. BloodBank.software's APIs connected us in four weeks. Orders flow automatically from our Epic system. Results flow back automatically. We eliminated manual entry entirely. Same result as traditional integration, at a fraction of the cost.
FAQ
Questions about EHR integration
Systems supported, timelines, consultants, security, sandbox testing, field mapping, and cost.
Q01 What hospital systems can we integrate with?
Any system with API or HL7 capability — Epic, Cerner, OpenEMR, Medidata, VistA, and custom-built systems are all supported. If your hospital system has an API or can output HL7, integration is possible.
Q02 How long does integration typically take?
Two to four weeks from kickoff to go-live, depending on complexity and your IT team's availability. Simple integrations run one to two weeks; complex ones with custom logic, four to six.
Q03 Do we need expensive integration consultants?
No. We provide clear API documentation and technical support, and your IT team can handle the integration. We answer technical questions; you control the timeline and the cost.
Q04 Can we integrate multiple hospital locations?
Yes. Once one location is integrated, adding more is straightforward — the same API against a different instance. Each location can run its own blood bank system or share a central one.
Q05 What if our hospital system is custom-built?
That's fine. We provide REST APIs and can talk through what your system can do. Your developers write the integration code; we supply the endpoints and the data access.
Q06 How is data protected in transit?
All communication is encrypted with TLS 1.3, authentication is via OAuth 2.0, API keys are protected, and data is encrypted at rest on HIPAA-compliant infrastructure. Your data stays under your control.
Q07 Can we test the integration before going live?
Yes. There's a sandbox environment with sample data, so your team can test without risk and promote to production once they're confident.
Q08 What happens if the integration breaks?
Our support team helps troubleshoot. Most issues turn out to be on the hospital system side — configuration, firewall, authentication — and we provide logs and debugging information to find them quickly.
Q09 Can we integrate specific data fields only?
Yes. Map the fields you want from the hospital order to the blood bank order and exclude the rest. The mapping is customised to your workflow.
Q10 Does EHR integration cost extra?
No additional licensing cost — API access is included in the platform. The only cost is your IT team's time. No consulting fees are required, though we can recommend consultants if you want the help.
