# Survey Tracking Implementation - Summary

## ✅ Implementation Complete

The survey tracking system has been successfully implemented and tested. This system provides comprehensive tracking of patient survey engagement throughout their journey.

## What You Can Now Track

### 1. Survey Delivery ✅
- **When the survey link is sent** - `sent_at` timestamp
- Total surveys sent per campaign
- Tracking of sent status

### 2. Survey Opens ✅
- **How many patients opened the link** - `open_count` field
- **When they opened it** - `last_opened_at` timestamp
- Time from send to first open
- Open rate calculation

### 3. Survey Completions ✅
- **How many patients filled the survey** - `status='completed'`
- **When they completed it** - `completed_at` timestamp
- Time from send to completion
- Time from open to completion - `time_spent_seconds`
- Completion rate (completed / sent)
- Response rate (completed / opened)

### 4. Survey Abandonment ✅
- **How many opened but didn't complete** - `status='abandoned'`
- Abandonment rate (abandoned / started)
- Average questions answered before abandonment
- Common abandonment points

### 5. Time Tracking ✅
- Average time to complete survey
- Fastest completion time
- Slowest completion time
- Time per question
- Peak engagement hours

## Key Features Implemented

### Database Changes
- ✅ Enhanced `SurveyInstance` model with tracking fields
- ✅ New `SurveyTracking` model for detailed event tracking
- ✅ Database indexes for performance
- ✅ Migrations applied successfully

### Analytics Functions
- ✅ `get_survey_engagement_stats()` - Overall performance metrics
- ✅ `get_patient_survey_timeline()` - Individual patient journey
- ✅ `get_survey_completion_times()` - Completion time statistics
- ✅ `get_survey_abandonment_analysis()` - Abandonment patterns
- ✅ `get_hourly_survey_activity()` - Time-based activity data

### API Endpoints
- ✅ `/api/surveys/api/analytics/engagement/` - Overall stats
- ✅ `/api/surveys/api/analytics/completion-times/` - Timing analysis
- ✅ `/api/surveys/api/analytics/abandonment/` - Abandonment analysis
- ✅ `/api/surveys/api/analytics/hourly-activity/` - Activity patterns
- ✅ `/api/surveys/api/analytics/patient-timeline/<id>/` - Patient journey
- ✅ `/api/surveys/api/tracking/<id>/` - Detailed tracking events

### Admin Interface
- ✅ Enhanced SurveyInstance admin with tracking fields
- ✅ New SurveyTracking admin panel
- ✅ Filters for status, time, device, browser
- ✅ Export functionality

### Frontend Integration
- ✅ Automatic tracking in survey form
- ✅ Device/browser detection
- ✅ Event recording (page view, start, answer, complete)
- ✅ Time tracking

## Test Results

```
✓ All models loaded successfully
✓ All tracking fields present
✓ Enhanced status choices working
✓ All analytics functions working
✓ Existing data accessible
✓ System ready for production use
```

Current state from database:
- Total survey instances: 18
- Open rate: 27.78%
- Completion rate: 16.67%
- Abandoned surveys: 2
- Tracking events ready to be collected

## How to Use

### For Admin Users
1. Go to `/admin/surveys/`
2. View survey instances with tracking data
3. Filter by status, time to complete, etc.
4. Export data for reporting

### For Developers
```python
from apps.surveys.analytics import (
    get_survey_engagement_stats,
    get_patient_survey_timeline,
    get_survey_completion_times,
    get_survey_abandonment_analysis,
    get_hourly_survey_activity,
)

# Get overall stats
stats = get_survey_engagement_stats()

# Track patient journey
timeline = get_patient_survey_timeline(patient_id)

# Analyze completion times
times = get_survey_completion_times()

# Find abandonment patterns
abandonment = get_survey_abandonment_analysis()

# View hourly activity
activity = get_hourly_survey_activity(days=7)
```

### For API Consumers
Use the analytics endpoints to get real-time data:
```bash
GET /api/surveys/api/analytics/engagement/
GET /api/surveys/api/analytics/patient-timeline/<patient_id>/
GET /api/surveys/api/analytics/completion-times/
GET /api/surveys/api/analytics/abandonment/
GET /api/surveys/api/analytics/hourly-activity/
```

## Benefits

1. **Complete Visibility**: Track every step of the patient survey journey
2. **Data-Driven Decisions**: Use analytics to optimize survey design
3. **Performance Metrics**: Measure open rates, completion rates, abandonment
4. **Timing Insights**: Understand how long patients take to complete surveys
5. **Device Analytics**: Know which devices/browsers patients use
6. **Patient-Level Tracking**: Follow individual patient journeys
7. **Real-Time Data**: Access current metrics via API
