Injury-Triage Assistant AI Agent

Take what a member describes, run the club's red-flag rules over it, and route them to a named clinician on shift — the agent records the description and the destination, and decides neither.

What this agent does

Routes the member, does not assess the injury

In
01

Intake in the member's own words, from the club app, the front-desk kiosk, a coach or the clinic's form.

02

Normalisation of site, side, onset and mechanism into the fields the club's pathway expects.

Reason
03

Red-flag rules first, ahead of the model, on the terms the club's clinician signed.

04

Routing rules configured per site — who covers what, on which days, from when.

05

Destination checks against the current directory, so nothing routes to a service that closed.

Decide
06

Anything outside the configured pathways is marked unrouted, not guessed.

07

Handover to the named clinician or duty first-aider on shift.

Out
08

Retention of the description, the rule that fired, the destination and the clinician on it.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent records what was described and where it was sent; a named clinician decides what is wrong, and the club answers for the care.

Example workflow

One description, intake to pick-up

AgentHuman
1Description receivedClub app, front-desk kiosk, coach referral or clinic intake form
2Words capturedSite, side, onset and mechanism, each kept in the words the member used for it
3Route draftedDestination, the rule that fired and match confidence
4Controls appliedRed-flag rules, pathway and staffing checks, directory verification and the confidence threshold
No human action required

Stages 1 to 4 run unaided, and nothing clinical is decided at any of them — the agent describes and routes, and the clinician's lane opens at the gate.

5DecisionBranches at the red-flag screen
Clear match

Goes to the named clinician on shift.

Flag or doubt

Goes to the duty clinician at once.

Clinician pick-up

The routing arrives with the description, the rule that fired and the destination.

Accept · Redirect · Escalate to urgent
Accepted — a clinician owns it
6Member record updatedOnly where write access and routing policy allow it
7Outcome evaluatedRedirect rate, time to pick-up, under-triage cases and what the clinician found
Redirects

A clinician redirect is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items
Deciding what the problem is, or how serious it is.
Telling a member to rest, train on or self-manage.
Resolving a red-flag presentation in the conversation.
Clearing anyone to return to play or to train.
Automation boundaryAgent acts unaided
Record what the member describes, in the words they described it in.
Run the club's red-flag rules before anything else runs.
Check the destination is one the club currently staffs.
Hand it to the named clinician on shift, and log who picked it up.
Any write happens inside the boundaries agreed at implementation, never ahead of a clinician.
Judging whether a concussion has happened.
Naming a condition, a tissue or a likely cause.
Interpreting a scan, a wearable stream or a test.
Changes to the red-flag list or the pathways.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every descriptionFrom the member's words
03Routing

Match the pathway

Work from the red-flag rules the club's clinician signed and the pathways it staffs.

01Approved path

Route it, do not read it

The description reaches a named clinician without a queue to watch.

02Human review

Send red flags straight through

Red-flag rules fire ahead of the model, so a presentation that cannot wait moves before anything is weighed.

04Build an evidence trail

What was described, what routed it and who picked it up stay on the record.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls

Six layers between the model and the member

Every layer wraps the next. What none of them catches is in the map below.

How Nestack evaluates it

Evaluate the routing workflow — not only the destination it picked.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — what the member is told
Depth of coverage ▼
E1Final-output evaluationDid the routing match the pathway the club configured?
E2Step-level evaluationDid the agent use the description given, the current rules and the live directory?
E3Tool evaluationDid it write to the right member record and the right clinic diary?

Affected slices

The aggregate buries one presentation

Aggregate redirect rates hold steady while back pain with leg symptoms absorbs the redirects. Nestack reports the clinician-redirect rate by presentation type, not only in total.

Evidence-linked improvement

What happens after a bad routing

The loop shuts when the miss is a case in the suite, not when it has been explained. That suite is what the next routing out of intake is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Redirect rate rises in a presentation type.

02Diagnose

Which rule fired, and on what words? A clinician reads back until one cause is left.

03Improve

Whatever changes ships against a version, with the presentations that prompted it attached.

04Verify

Nothing ships until the affected cases pass a second time.

05Learn

The suite grows by one case; so does the red-flag list.

Learn → DetectThe return edge. What the next miss is measured against has grown by one.

Typical build scope

Twelve workstreams across six weeks

The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, routing workflow, evaluation, integration, then production validation and handover.

Four phases across six weeks

The bands follow real work rather than a plan, so evaluation and pilot genuinely share the fifth week.
