Healthcare
Building healthcare software that survives an audit
In most software, you ship the feature and move on. In clinical systems, you also have to be able to prove — months later — exactly what happened and who did it.
Write the audit trail first
Teams often treat logging as something to add before launch. In healthcare that ordering is backwards. Retrofitting an audit trail means reconstructing intent for code that was written without it, and the gaps you leave are precisely the ones an auditor will find.
Decide early what a recorded event looks like: who acted, what record changed, what the previous value was, when, and from where. Then make it impossible to change a clinical record through a path that does not produce one.
Access control is a clinical requirement
"Everyone can see everything" is convenient during development and indefensible in production. Roles need to reflect how the clinic actually operates — a receptionist scheduling an appointment does not need the consultation notes, and a locum covering one afternoon should not retain access the following month.
Two practices that repay the effort:
- Time-bound access, so temporary staff expire automatically rather than by someone remembering.
- Read access logged as carefully as writes. In a privacy incident, who looked is usually the question.
Deletion is rarely deletion
Clinical records generally cannot be hard-deleted, but users still need a way to correct mistakes. The pattern that works is amendment rather than removal: the original stays, the correction is recorded alongside it, and the interface shows the current value while keeping history reachable. A wrong entry that quietly disappears is a much bigger problem than a wrong entry that is visibly superseded.
Uptime has a clinical cost
An outage in a retail app costs sales. An outage in a clinic means staff fall back to paper, and someone has to reconcile it afterwards. Plan the degraded mode deliberately: what stays available read-only, how paper records get back in, and who decides to switch over. Practise it before you need it.
Build for the handover
Healthcare systems outlive the teams that build them. Document the data model, the access rules and the integration points as you go, in language a clinician or a future developer can follow. If your system cannot be explained to the people who depend on it, it is not finished.
