Introduction
In the healthcare industry, monitoring patient health data efficiently is crucial for better decision-making and improved patient outcomes. Power BI provides a powerful platform to visualize and analyze patient health metrics in real time. This guide walks you through creating a Patient Health Monitoring Dashboard using Power BI, demonstrating practical applications with sample tables.
Step 1: Understanding the Data Model
To create an effective health monitoring dashboard, we use structured datasets representing patient information, vitals, and treatment details. Below are the primary tables involved:
1. Patients Table
This table stores basic patient details.
| PatientID | Name | Age | Gender | Contact |
|---|---|---|---|---|
| 1001 | John Smith | 45 | Male | +1234567890 |
| 1002 | Jane Doe | 38 | Female | +9876543210 |
2. Vitals Table
Tracks patient vitals such as heart rate, blood pressure, and temperature.
| VitalID | PatientID | HeartRate | BloodPressure | Temperature | RecordedAt |
| 2001 | 1001 | 78 | 120/80 | 98.6°F | 2024-02-12 |
| 2002 | 1002 | 85 | 130/85 | 99.1°F | 2024-02-12 |
3. Medications Table
Stores prescribed medications for patients.
| MedID | PatientID | Medication | Dosage | Frequency |
| 3001 | 1001 | Aspirin | 75mg | Once Daily |
| 3002 | 1002 | Metformin | 500mg | Twice Daily |
4. Appointments Table
Tracks patient appointments and doctor consultations.
| AppointmentID | PatientID | Doctor | Date | Status |
| 4001 | 1001 | Dr. Lee | 2024-02-15 | Confirmed |
| 4002 | 1002 | Dr. Kim | 2024-02-16 | Pending |
Step 2: Creating the Power BI Dashboard
1. Data Import & Transformation
- Connect Power BI to data sources like SQL Server, Excel, or cloud services.
- Use Power Query Editor to clean and transform data.
2. Building Visuals
- Patient Overview: A table visual displaying patient demographics and recent checkups.
- Vital Trends: A line chart tracking patient vitals over time.
- Medication Adherence: A bar chart showing prescribed vs. completed medication intake.
- Appointment Status: A pie chart representing scheduled, completed, and pending appointments.
3. Implementing DAX Measures
- Average Heart Rate:
AvgHeartRate = AVERAGE(Vitals[HeartRate]) - Blood Pressure Alerts:
BPAlert = IF(Vitals[BloodPressure] > 140/90, "High", "Normal") - Missed Appointments:
MissedAppointments = COUNTROWS(FILTER(Appointments, Appointments[Status] = "Missed"))
Step 3: Deploying & Sharing the Dashboard
- Publish to Power BI Service for remote access.
- Enable scheduled refresh for real-time updates.
- Share via Power BI Workspaces to facilitate collaboration among healthcare teams.
Conclusion
A Patient Health Monitoring Dashboard in Power BI enhances healthcare analytics by providing real-time insights into patient vitals, medications, and appointments. This empowers doctors and administrators to make data-driven decisions, ultimately improving patient care. Join our SQL Forum to explore more Power BI use cases and share your insights.
