QR codes for hospitals
Hospital QR codes work at institutional scale only with a register: every code's URL, location, owner and review date recorded, one template, one domain. The highest-value chain runs from the car park to the ward: wayfinding codes at each decision point, never carrying patient data.
Run codes like estates runs signs
The clinical rules (no patient data in payloads, printed alternatives always, wristband constraints) are on the healthcare page. What a hospital adds is scale: hundreds of codes across dozens of departments, printed by different teams over years. Without governance, that decays into dead links on permanent signage.
The fix is a code register, exactly like an estates asset list: for every code, its URL, physical location, owning department, print date and next review date. Add every new code at print time; walk the register annually with a phone. A hospital that cannot say how many QR codes it has displayed has some pointing at retired pages, link rot on a laminated sign outlives the intranet page it pointed to.
One template, one official domain, and bulk generation from the register keeps the estate consistent.
The parking-to-ward problem
The hardest journey in the building starts in the car park: anxious visitor, unfamiliar site, appointment letter naming a ward. Chain the codes along the actual decision points:
| Point | Code links to |
|---|---|
| Appointment letter | Directions page for that clinic, plus a geo pin for the right car park |
| Car-park exit | Site map with walking routes |
| Main entrance and each junction | Step-free route to each department |
| Lift lobbies | Floor directory |
Corridor sizing and mounting heights follow the healthcare signage numbers; pair every code with printed directions, since many visitors will not scan.
Visitor information
Ward-specific visiting hours, what to bring, infection-control rules, printed on the ward door with a code to the live version. The printed sheet answers today's visitor; the code stays correct when policy changes tomorrow.
Discharge and the token pattern
Discharge codes may link generic aftercare pages freely. Anything patient-specific must use an opaque token resolved by an authenticated portal, the token-not-record pattern, so a photographed letter leaks nothing. Never encode the record; encode a pointer only the system can resolve.
FAQ
How should a hospital manage hundreds of QR codes?
With a register: URL, location, owner, print date and review date for every code, managed like any estates asset list. Review annually with a phone in hand. Unregistered codes on permanent signage are how hospitals end up with laminated dead links.
What should hospital wayfinding QR codes link to?
The step-free route to a specific destination from the code's own location, not a generic site map. The appointment letter's code should carry the clinic's directions page and the correct car park, since the journey starts before the building.
Can discharge instructions go behind a QR code?
Generic aftercare pages, yes. Patient-specific instructions need an opaque token that an authenticated portal resolves, so the code on a photographable letter identifies nothing. A printed copy must always accompany the code.
