Patient Intake Processor Alerts on Critical Allergies Instantly (8 Nodes) 🔥

Duy Bui

3d • General Discussion 💬

Medical clinic. Patient fills intake form. Someone types it all into system. Allergy information buried on page 3.

Built intake processor. Critical allergies trigger instant alert. Different Slack channel. Staff knows immediately.

THE HEALTHCARE DOCUMENTATION RISK:

Penicillin allergy on form. Nurse doesn't see it until patient is in room. Doctor almost prescribes it.

Near miss. Documentation existed. Wasn't surfaced fast enough.

THE DISCOVERY:

Document extraction pulls complete patient information. Code checks allergies against critical list. Different routing based on severity.

Critical allergies go to urgent channel. Everyone sees it.

THE WORKFLOW:

Google Drive trigger watches intake forms → Download PDF → Document extraction pulls patient info, insurance, medical history, medications, allergies → Code processes and checks for critical allergens → Sheets creates patient record → IF checks critical allergy → TRUE: Slack urgent channel alert → FALSE: Slack routine intake notification.

8 nodes. HIPAA-aware design.

THE CRITICAL ALLERGY DETECTION:

Code maintains critical allergen array: penicillin, sulfa, latex, iodine, aspirin, nsaids.

Patient allergy list checked against array. Any match triggers urgent routing.

Different Slack channels: #critical-alerts vs #patient-intake. Staff knows the difference.

THE DATA EXTRACTION:

JSON Schema captures: Patient info (name, DOB, contact), insurance details, medical history, current medications with dosages, allergies with reaction severity, emergency contact, reason for visit.

Code calculates age from DOB. Formats medications list. Flags "NKDA" if no allergies.

THE TRANSFORMATION:

Before: Manual data entry. Allergy information buried. Near misses happen.

After: Automatic extraction. Critical allergies surfaced instantly. Staff prepared.

THE NUMBERS:

200 intake forms monthly

6 critical allergens monitored

Instant alert on match

Data entry: 15 minutes → 2 minutes review

HIPAA NOTE: Self-hosted n8n recommended for PHI.
