Vessel Health moved 11,000 patient messages a month off its clinicians' plates

Vessel Health runs nineteen clinics and a patient portal that generates around 11,000 messages a month. Most are administrative — appointment changes, repeat prescription requests, insurance queries — but they arrive in the same queue as the clinical ones, and until 2025 a nurse read every single one to work out which was which.

The constraint was never the automation

Priya Alderton had evaluated four tools before Dispatch. Each of them could sort a queue. None of them could answer the question her compliance officer opened every meeting with: show me, for this specific message, why the system did what it did.

Anything that makes a decision about a patient message has to be able to explain the decision afterwards. Not in aggregate. For that message, on that day.

That requirement eliminated most of the market. A confidence score is not an explanation.

What the audit log had to contain

Vessel's approval hinged on four properties, and the team wrote them down before the pilot started:

1. Every automated action is recorded with the message it acted on and the instruction it followed
2. The record is written before the action, not after, so a failure cannot erase its own trail
3. Nothing clinical is ever auto-answered — only routed, and only to a named queue
4. Any action can be reversed by a human for thirty days, and the reversal is itself logged

Dispatch met the first three out of the box. The fourth already existed as undo; what Vessel needed was for the reversal to appear in the same export their SIEM ingests.

Where it landed

Administrative messages — about 78% of the queue — are now sorted, answered where the answer is a fact, and closed without a clinician reading them. Clinical messages are routed to the right specialty within a minute and are never touched by an agent.

The measure Priya cares about is not time saved. It is that the nurses who used to spend their first ninety minutes sorting a queue now spend it on the twenty patients who needed a person.

The compliance team, for its part, exports the log weekly and has raised two questions in nine months. Both were answered from the log itself.
