Scope
One telephone line and the calls the hospital itself chooses. Until the hospital has accepted it, the calls are practice calls, not real patients.
sostriage
A defined trial, not a finished rollout
The hospital can see one workflow, with a clinician on every outcome, before anything is used in ordinary service.
Safety
A clinician owns the outcome. Red cannot be closed as home. The caller does not hear that help is on the way until the handover is confirmed.
What can be measured
Whether the opening was complete, how soon a red finding was raised, and whether the handover was confirmed. These are measures that can be agreed. They are not published results.
The decision afterwards
The hospital can go on, change the workflow, or stop. The trial does not commit anyone to a purchase.
