Track medicine adherence and monitor patients with Google Sheets, OpenAI and Slack

🩺 AI-Powered Medicine Reminder & Patient Monitoring Workflow (n8n + Google Sheets + OpenAI + Slack)

This workflow automates medicine reminders, tracks patient responses and alerts doctors in critical situations using n8n, Google Sheets, OpenAI and Slack.

Quick Implementation Steps

Connect your Google Sheets with patient data Set up Slack (or replace with Gmail/SMS nodes) Configure Webhook to receive patient replies Add your OpenAI API key Define reminder times in HH:mm format Activate the workflow scheduler

💡 You can replace Slack with Email (Gmail) or SMS APIs like Twilio.

What It Does

This workflow automates the entire lifecycle of patient medicine adherence tracking. It periodically checks patient records and sends reminders when it's time to take medicine.

When a patient responds, the system captures the reply via webhook and uses AI to classify the response into categories such as taken, not taken, delayed or unclear. It then updates patient records and tracks missed doses.

If a patient repeatedly misses medication or shows signs of distress, the system flags it as critical and alerts the doctor immediately through a separate channel.

Who’s It For

Healthcare providers and clinics Telemedicine platforms Caregivers managing patients Health-tech startups Remote monitoring systems

Requirements

n8n (cloud or self-hosted) Google Sheets account Slack account (or Email/SMS alternative) OpenAI API key Google Sheet with following columns Name Phone Medicine Reminder Time Last Response Last Patient Message Status Missed_Count

⚠️ Reminder Time must be in 24-hour format (HH:mm) Example: 08:30, 14:45, 21:00

Webhook Input Format

Your system must send patient replies in this format:

{ "phone": "string", "message": "string" }

How It Works

1. Scheduler Trigger

Runs every minute Checks all patient records

2. Fetch Patient Records

Reads all rows from Google Sheets

3. Match Reminder Time

Compares current time with patient’s reminder time

4. Send Reminder

Sends message via Slack (or Email/SMS alternative)

5. Receive Patient Response

Webhook captures incoming responses

6. AI Classification

Classifies response into:

TAKEN** NOT_TAKEN** LATER** CONFUSED**

Also detects critical conditions

7. Parse Output

Ensures valid JSON format

8. Match Patient

Matches phone number with Google Sheet

9. Update Missed Count

NOT_TAKEN** → +1 LATER** → +1 TAKEN** → reset to 0

10. Check Critical Condition

Triggered when:

is_critical = true OR Missed_Count >= 3 (configurable)

11. Critical Flow

Update status to CRITICAL Alert doctor via separate channel

12. Normal Flow

Update patient record Send response: NOT_TAKEN → Reminder LATER → Gentle follow-up TAKEN → Appreciation

Customization

Troubleshooting

| Issue | Possible Cause | Solution | |--------------------------|--------------------|--------------------------| | Reminder not sent | Time mismatch | Use HH:mm format | | Patient not matched | Phone mismatch | Ensure same format | | AI parsing error | Invalid JSON | Check parsing node | | Missed count issue | Wrong classification| Verify AI output | | Webhook not working | Wrong endpoint | Check URL | | Slack not sending | Credentials issue | Reconnect Slack | | Critical not triggered | Condition issue | Adjust threshold |
