|
|
## Executive Summary
|
|
|
|
This document provides a comprehensive examination of three interconnected systems in the PX360 platform:

|
## 2. JOURNEY SYSTEM
|
|
|
|
### Overview
|
|
The journey system tracks patient progress through hospital visits and stages, enabling automated survey triggering at discharge.
|
|
|
|
### Key Components
|
|
|
|

|
|
- Stages with triggers and timing
|
|
- Survey automation settings
|
|
|
|
**PatientJourneyInstance**
|
|

|
|
- Links to patient, hospital, and template
|
|
- Encounter ID (hospital admission ID)
|
|
- Status: ACTIVE → COMPLETED
|
|
- Journey timeline tracking
|
|
|
|
**PatientJourneyStageInstance**
|
|

|
|
- Links to journey instance and stage template
|
|
- Trigger event codes from HIS
|
|
- Status: PENDING → IN_PROGRESS → COMPLETED

|
|
|
|
#### 2.2 Journey Stages
|
|
|
|
**Typical OPD Journey Stages:**
|
|
1. **Registration** - Patient registration/check-in
|
|
2. **Consultation** - Doctor consultation
|
|
3. **Investigation** - Tests/diagnostics
|
|
4. **Treatment** - Treatment/procedures
|
|
5. **Discharge** - Patient discharge
|
|
|
|
**Journey Configuration:**
|
|
- Trigger event codes from HIS system
|
|
- Expected timing for each stage
|
|
- Conditional stage activation
|
|
- Stage dependencies
|
|
|
|
#### 2.3 Journey Automation
|
|
|
|
**Automatic Stage Completion:**
|
|
- HIS adapter processes visit data
|
|
- Matches visit types to stage triggers
|
|
- Automatically completes stages
|
|
- Timestamps stage completion
|
|
|
|
**Automatic Survey Triggering:**
|
|
- Detects discharge event
|
|
- Checks journey completion
|
|
- Triggers post-discharge survey
|
|
- Uses appropriate delivery channel
|
|
|
|

|
## 7. TROUBLESHOOTING
|
|
|
|
### Common Issues
|
|
|
|
#### Issue 1: Survey Not Triggered
|
|
**Symptom:** Patient discharged but survey not sent
|
|
|
|
**Possible Causes:**
|
|
1. Journey template doesn't have `send_post_discharge_survey=True`
|
|
2. Journey status not set to COMPLETED
|
|
3. Discharge date not set in HIS data
|
|
|
|
**Solution:**
|
|
```python
|
|
# Check journey template
|
|
journey_template.send_post_discharge_survey = True
|
|
journey_template.save()
|
|
|
|
# Check journey status
|
|
journey.status = "COMPLETED"
|
|
journey.completed_at = discharge_date
|
|
journey.save()
|
|
```
|
|
|
|
#### Issue 2: Email Delivery Failed
|
|
**Symptom:** Survey status stays PENDING
|
|
|
|
**Possible Causes:**
|
|
1. Patient has no email address
|
|
2. Email address is invalid
|
|
3. NotificationService API not responding
|
|
4. SMTP not configured
|
|
|
|
**Solution:**
|
|
```python
|
|
# Check patient email
|
|
patient.email # Should not be None or empty
|
|
|
|
# Check NotificationService logs
|
|
from apps.notifications.models import NotificationLog
|
|
logs = NotificationLog.objects.filter(channel="EMAIL").last()
|
|
|
|
# Check survey status
|
|
survey.status # Should be SENT if successful
|
|
```
|
|
|
|
#### Issue 3: NOT NULL Constraint Violation
|
|
**Symptom:** `NOT NULL constraint failed: organizations_patient.email`
|
|
|
|
**Solution:**
|
|
```python
|
|
# Use NULL-safe email handling
|
|
email = patient_data.get("Email")
|
|
email = email if email else '' # Convert None to empty string
|
|
```
