Raw Blame History

Survey, Journey, and Survey Simulator Examination

Executive Summary

This document provides a comprehensive examination of three interconnected systems in the PX360 platform:

Survey System - Patient experience survey creation, delivery, and collection
Journey System - Patient journey tracking through hospital visits and stages
Survey Simulator (HIS Simulator) - Mock Hospital Information System for testing

All three systems are FULLY FUNCTIONAL and PRODUCTION-READY.

1. SURVEY SYSTEM

Overview

The survey system manages patient experience surveys from creation to delivery and response collection.

Key Components

1.1 Survey Models

File: apps/surveys/models.py

SurveyTemplate

Defines survey structure (questions, sections)
Supports multiple survey types (IPD, OPD, Post-Discharge)
Active/Inactive status management
Hospital-specific templates

SurveyInstance

Individual survey sent to a patient
Links to patient, journey instance, and hospital
Delivery channels: SMS, EMAIL
Status tracking: PENDING → SENT → COMPLETED/EXPIRED
Recipient information (phone, email)

SurveyResponse

Patient's responses to survey questions
Links to survey instance and patient
Stores answers as JSON
Timestamps for submission

1.2 Survey Services

File: apps/surveys/services.py

SurveyDeliveryService

Main service for delivering surveys
Supports multiple delivery channels (SMS, EMAIL)
Integrates with NotificationService API
Updates survey status based on delivery result
Handles delivery failures and retries

Key Methods:

@staticmethod
def deliver_survey(survey_instance: SurveyInstance) -> bool:
    """Deliver survey via appropriate channel"""
    if delivery_channel == "SMS":
        # Send SMS via NotificationService
    elif delivery_channel == "EMAIL":
        # Send email via NotificationService

1.3 Survey Delivery Channels

SMS Channel

Used for initial implementation
Sends survey link via SMS
Integrated with NotificationService API
Supports retry logic (3 attempts)

EMAIL Channel ✅ NEW

Implemented for HIS integration
Sends survey invitation email
Patient-friendly subject and template
Higher engagement rate expected
Full notification logging

1.4 Survey Templates

Available Templates:

OPD (Outpatient Department) Survey
IPD (Inpatient Department) Survey
Post-Discharge Survey
Physician-specific surveys
Department-specific surveys

Template Features:

7. TROUBLESHOOTING

Common Issues

Issue 1: Survey Not Triggered

Symptom: Patient discharged but survey not sent

Possible Causes:

Journey template doesn't have send_post_discharge_survey=True
Journey status not set to COMPLETED
Discharge date not set in HIS data

Solution:

# 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:

Patient has no email address
Email address is invalid
NotificationService API not responding
SMTP not configured

Solution:

# 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:

# Use NULL-safe email handling
email = patient_data.get("Email")
email = email if email else ''  # Convert None to empty string
