01/12MODULE: PROBLEM SPACE

The Challenge

Neurological symptoms trigger defensive imaging, yet missing a true emergency is unacceptable. Live Corp focuses on structured triage, not diagnosis.

Low-yield defensive imaging in low-risk presentations
Missed escalation for high-risk signs
Inconsistent documentation of red flags
CRITICAL IMPACT
Imaging Reduction
25-40%
Escalation Safety
+30%
faster recognition
02/12MODULE: INTERVENTION

What It Reduces / Improves

Reduces Defensive Imaging
BENEFIT 1

Reduces Defensive Imaging

Low-yield imaging in low-risk presentations is deferred

Improves Escalation Safety
BENEFIT 2

Improves Escalation Safety

High-risk signs are recognized and escalated faster

Standardizes Documentation
BENEFIT 3

Standardizes Documentation

Consistent red flag documentation and triage protocols

03/12MODULE: INPUTS

Input Sources

Symptoms
INPUT 1

Symptoms

Structured symptom onset and pattern

Vitals
INPUT 2

Vitals

Blood pressure, heart rate, temperature

Neuro Checks
INPUT 3

Neuro Checks

Simple guided checks (speech, coordination)

Audio/Video
INPUT 4

Audio/Video

Optional short capture for signal quality

04/12MODULE: ENGINE MAPPING

Decision Framework

RULE-OUT MODE

Benign pattern + stable vitals + no red flags → defer immediate imaging

Rule-Out
MINIMAL PANEL MODE

Recommend clinic evaluation or targeted pathway

Minimal Panel
ESCALATION MODE

Acute focal deficits → urgent evaluation

Escalation

How This Service Fits the Engine

The Neurological Symptom Triage Wing operates as a structured triage module within the Live Corp engine. It processes neurological symptoms, vitals, and simple neuro checks to identify red flags and escalate true emergencies while reducing defensive imaging in low-risk presentations.

PRIMARY FUNCTION

Structured red-flag triage for neurological symptoms

OPERATING MODE

ESCALATION + ABSTAIN
