Study Notes
Blockchain-enabled digital twin system for brain stroke prediction
- A digital twin is a virtual model of a real-world system updated in real-time
- Digital twins are used in healthcare for monitoring activities like diet, physical activity, and sleep
- Current research shows limited accuracy in predicting serious conditions like heart attacks, brain strokes, and cancers using digital twins
- Security and privacy concerns limit widespread adoption of digital twins
- A secure, machine learning-powered digital twin application was developed
- Objectives: enhance prediction accuracy, strengthen security, and ensure scalability
- Application accuracy for brain stroke prediction: 98.28%
- Data security enhanced by integrating consortium blockchain technology with machine learning
- Application is tamper-proof and automatically corrects backend data anomalies
- Extendible to other pathologies (heart attacks, cancers, osteoporosis, epilepsy) with minor configuration changes
Introduction
- Digital twins are digital representations of real-world entities
- Significant strides towards using digital twins in healthcare
- Digital twins employed in hospitals for operations, staffing and care delivery
- Remote patient monitoring (RPM)
- Headless architecture: front-end (user interface) is decoupled from back-end (business logic and data)
- Allows independent data collection from medical devices
- Enables content/data via API to any front-end/device
- Potential of digital twins in healthcare, especially for predicting serious illnesses
- Most studies focus on individual organs/systems, with limited real-world implementation
Literature Review
- Digital twin frameworks used to predict pathologies like brain stroke
- Integrating patient data with computational techniques
- Studies explored application of digital twins to enhance stroke prediction, accuracy, and outcomes
- Various frameworks using machine learning algorithms, physiological models, and advanced analytics
- Most are limited to specific organs or a single condition
- Reported accuracy levels vary (e.g., 85%, 90%, 92%)
Methods
- ML based Digital Twin application for predicting brain strokes
- Uses a public dataset (Kaggle)
- Dataset encompasses 4,981 records
- Population distribution: 58% females, 42% males
- Ages range between 8 months - 82 years
- 66% are married
- 57% private employees
- Additional synthetic data generated for simulations
- Data stored in three files: “Patient_EHR.csv, Patient_SuppData.csv, Patient_RealData.csv"
- Includes long-term data (heart disease, cancer, diabetes, stroke)
- Data includes patient demographics and lifestyle information
- Model limitation: less diverse population, missing temporal data, lack of comorbidities
Digital twin environment setup
- Data security: consortium blockchain model using a Ganache private blockchain emulator
- Distributed architecture (multiple hospitals)
- Data validated and maintained by nodes
- Reduces single-point-of-failure risk
- Data integrity is maintained with smart contracts in Solidity
- Patient data stored in a PostgreSQL database
- Metadata (hashes, timestamps) stored on the blockchain
- Hybrid approach: efficient data management while preserving blockchain security
Digital twin application accuracy
- Conditions for detecting brain stroke
- Hypertension present (Value = 1)
- Heart disease present (value=1)
- Systolic blood pressure > 180 mmHg
- Serum cholesterol > 240 mg/dL
- Fasting blood glucose 100-125 mg/dL
- Maximal heart rate exceeds age-related prediction
- OL peak exceeds 123
Digital twin application scalability
- Adaptation to other conditions (heart attacks, cancers, osteoporosis) with minor configuration changes
- Usable for varied conditions without code modifications
- Uses logistic regression to predict stroke risk
- Adaptable features improve wider application
