07Systems that actually talk to each other.
Integration that holds when the upstream changes.
Interoperability is rarely a standards problem. It is a problem of edge cases, local conventions and the one field a vendor uses differently to everyone else.
The problem
Connected on the diagram. Not in practice.
Two systems exchange messages successfully for months, then an upstream upgrade changes a segment and results stop arriving. Nobody notices until a clinician asks where a lab came back.
What it usually looks like
- Interfaces that fail silently and are discovered by users
- Staff re-keying data between systems that are nominally integrated
- A vendor upgrade that requires interface rework nobody scoped
- No single view of which interfaces exist or who owns them
How we work
Built for variation, monitored for silence.
Standards-based where standards hold, explicitly mapped where they do not, and instrumented so a failure raises an alert rather than a complaint.
- 01
Standards plus reality
HL7 v2, FHIR and modern APIs, with the local variation documented rather than assumed away.
- 02
Fails loudly
Monitoring and alerting on message flow, so a stopped interface is detected in minutes.
- 03
Documented and owned
An inventory of what connects to what, and who is responsible when it changes.

Our approach
How an engagement runs
- 01
Understand
What connects to what today, including the interfaces nobody has documented.
- 02
Assess
Message flow, failure modes, ownership and the upgrades on the horizon.
- 03
Build the strategy
What to rebuild, what to monitor, and what to retire.
- 04
Deliver
Interfaces built and tested against real message variation, not just the specification.
- 05
Support
Monitoring, runbooks and support through vendor upgrades.
Why Calsoft
Why healthcare integration with Calsoft
We expect the edge cases
Every site has local conventions. Integration work that assumes otherwise breaks on contact.
Silence is the real risk
Most integration damage comes from failures nobody was alerted to.
Clinical consequence in view
A missing result is not a data incident. We treat it accordingly.

FAQ
Questions we are asked
Yes. Replacing an interface engine is a large undertaking and frequently unnecessary — most of the value comes from better-built interfaces, monitoring and documentation.
