STG Triage

Offline Expo app for Android and iOS built around the Ghana Standard Treatment Guidelines (STG), 7th edition (2017).

The app now has two clearly separated workflows:

• Guided triage: a stricter, age-aware rules engine that ranks only curated STG conditions
• STG reference: a broader offline disease/section lookup across the searchable STG corpus

What it does

• Collects age, duration, symptoms, and signs separately.
• Supports guided triage with structured STG buckets plus manual symptom/sign entry.
• Ranks likely conditions locally on-device using curated age-aware STG logic.
• Lets users search STG diseases/conditions by name with typo-tolerant offline search.
• Shows treatment options, investigations, red flags, and source section/page references from the STG.
• Uses no authentication, no backend, and no external API calls.

Current product shape

Guided triage

• Designed to return one careful primary STG answer first
• Uses age bands, hallmark findings, red flags, and duration windows
• Separates symptoms from signs / examination findings
• Keeps ranking limited to curated conditions instead of the full extracted corpus

STG reference

• Searches the broader offline STG corpus by disease/condition name
• Returns structured section content for confirmation and reference
• Labels entries as either:
  • Ranked by guided triage
  • Reference-only STG section

Local setup

npm install
npm start

Then open the Expo app on Android or iOS.

Validation

npm test
npx tsc --noEmit
npx expo-doctor
npx expo export --platform web

Curated guided-triage coverage

The ranked guided-triage layer currently includes:

• Vitamin A deficiency / xerophthalmia
• Constipation
• Peptic ulcer disease
• Gastro-oesophageal reflux disease
• Haemorrhoids
• Amoebic liver abscess
• Acute hepatitis
• Hepatic encephalopathy

Search/reference coverage

• The app includes a generated offline STG corpus built from the PDF table of contents and section extraction pipeline.
• All 30 STG chapters are accounted for in the searchable corpus.
• Search/reference coverage is broader than ranked triage coverage by design.

Notes

• This is an offline decision-support tool, not a substitute for clinical judgment or confirmed diagnosis.
• Accuracy is intentionally prioritized by keeping ranked diagnosis limited to curated STG conditions.
• The broader extracted STG corpus is available for reference search without being overclaimed as triage-quality ranking.
• The matching logic is transparent, lightweight, and designed to run fully on-device.
