MaternaCare - Maternal-Fetal Risk Assessment Application

A professional, production-ready web application for real-time assessment of maternal-fetal complications risk using advanced statistical analysis and clinical decision support.

Features

Core Functionality

• Patient Data Management - Intuitive input for maternal vital signs and clinical parameters
• Risk Assessment - Real-time computation of maternal-fetal complication risk using logistic regression
• Statistical Analysis - Principal Component Analysis (PCA) for dimensionality reduction and pattern detection
• Clinical Interpretation - Automated clinical notes and risk stratification with actionable recommendations
• CSV Import/Export - Batch processing of patient datasets with comprehensive error handling
• Report Generation - Print-ready clinical reports with visualization and recommendations

Advanced Analytics

• Bootstrap Confidence Intervals - 95% CI estimation for robust uncertainty quantification
• Vital Sign Normalization - Z-score standardization against reference population
• PCA Visualization - Interactive scatter plots showing patient clustering and risk patterns
• Fetal Heart Rate Monitoring - Baseline estimation and variability analysis
• Multi-Factor Risk Calculation - Weighted combination of maternal-fetal indicators

Technology Stack

• Frontend - React 18.3 with Vite 7.3
• Charts - Recharts for interactive visualizations
• Styling - CSS3 with modern design system and responsive layout
• Build Tool - Vite with optimized production builds
• Testing & Quality - ESLint compliance with 0 errors

Getting Started

Prerequisites

• Node.js 16+ and npm 7+
• Modern web browser (Chrome, Firefox, Safari, Edge)

Installation

# Clone the repository
git clone https://github.com/jachinsamuel/materncare.git
cd materncare

# Install dependencies
npm install

# Start development server
npm run dev

# Build for production
npm run build

# Preview production build
npm run preview

Usage

Patient Assessment

1. Enter maternal vitals (systolic BP, diastolic BP, heart rate, temperature, respiratory rate)
2. Enter fetal parameters (FHR baseline, FHR variability, gestational age)
3. App automatically computes risk score and generates clinical interpretation
4. Review recommendations and patient risk classification

Batch Processing

1. Prepare CSV file with columns: sbp, dbp, hr, temp, rr, fhr_baseline, fhr_var, ga
2. Click "Upload CSV" and select your file
3. Review results and export individual reports as needed

Risk Categories

• Low Risk (Green) - Score < 0.25
• Moderate Risk (Yellow) - Score 0.25-0.65
• High Risk (Red) - Score > 0.65

Clinical Algorithms

Risk Scoring

Risk calculation uses logistic regression:

risk = 1 / (1 + e^(-weighted_sum))

Where weighted_sum combines:

• Systolic BP (weight: 0.15)
• Diastolic BP (weight: 0.10)
• Heart Rate (weight: 0.12)
• Temperature (weight: 0.08)
• Respiratory Rate (weight: 0.08)
• FHR Baseline (weight: 0.18)
• FHR Variability (weight: 0.15)
• Gestational Age (weight: 0.14)

Vital Sign Ranges

All vital inputs are validated against clinical reference ranges with automatic clamping to prevent extreme values.

Architecture

Modular Design

• src/lib/statistics.js - 14+ statistical functions (mean, std, PCA, bootstrap, logistic regression)
• src/config/clinical.js - Clinical constants, weights, and reference populations
• src/utils/clinical.js - Clinical interpretation and report generation
• src/utils/validation.js - Input validation and sanitization
• src/utils/errorHandler.js - Comprehensive error handling and logging
• src/App.jsx - Main React component with UI state management

Performance Optimizations

• Memoization of expensive calculations (PCA, bootstrap)
• Efficient CSV parsing with streaming validation
• Responsive charts with optimized rendering
• Lazy loading and code splitting via Vite

Data Privacy & Security

• All calculations performed locally in the browser
• No patient data sent to external servers
• No persistent storage of patient information
• HIPAA-ready architecture (requires secure deployment)

Customization

Hospital-Specific Settings

Edit src/config/clinical.js to customize:

• Clinical weight coefficients
• Reference population statistics
• Vital sign ranges
• Risk thresholds and colors
• Clinical recommendation templates

Styling

Modify src/App.css CSS variables to match your hospital branding:

--primary-dark: #1a2b4a;
--accent-success: #2e7d5e;
--accent-warning: #b8860b;
--accent-danger: #c0392b;
