What it does
A register you can hand to an inspector
A drug box is not a stock item: it is controlled medication in a crew’s custody. EMS Relay keeps a live register per box and per slot, so the balance is always the sum of what was signed in and out.
Slot-level balances
Layouts such as adrenaline 10 × 1 mg. Withdraw 5 mg and five slots show empty — the balance is never a number someone typed.
Every movement has a reason
Initial load, replacement stock, returned unused, clinical use (linked to the PRF), expired, broken or handed over.
Schedule 5 and 6 witnesses
Disposals of scheduled medication need a witness, recorded with the entry.
Handovers with a name
When a box changes hands, the receiver’s details and signature go into the register.
Append-only and hash-chained
Entries can never be edited or deleted. A mistake is corrected by a signed-off counter-entry, and "Verify register" proves the chain is intact.
Monthly spot checks
A physical count against the register; any variance waits for a manager’s sign-off — the register never corrects itself.
Expiry and shortfalls flagged
Slots nearing expiry and boxes below their layout show up before a shift, not during an audit.

Custody you can see
Each box is with a vehicle, a person or the store, with its seal number on record.

On the PRF
One dose, recorded once
- The crew signs a dose out of the vehicle’s drug box from the treatment step of the PRF.
- The register entry is linked to the patient, and the PRF line is locked to it.
- The PRF and the register can never disagree, because they are the same entry.
Questions
Good to know
Why does EMS Relay track drugs per slot?
Because a drug box holds a fixed number of each drug. Tracking each slot means the balance is always what is physically in the box, and a missing ampoule shows up immediately.
Can a register entry be changed after it is recorded?
No. The register is append-only. A mistake is corrected with a counter-entry that a manager signs off, so the original stays visible.
Who can see the drug register?
Crews can read the register; creating boxes, layouts and the drug list is for management. Every entry shows who made it and when.
Can we export the register for an inspection?
Yes. Management can download the register as a PDF for any box, drug, reason, period or PRF.
