EHR & Claims Ingestion

Querying relational hospital databases, Epic/Cerner tables, and insurance claims.

Interoperability Standards

HL7 and FHIR (Fast Healthcare Interoperability Resources) data models.

Clinical KPI Modeling

Measuring Average Length of Stay (ALOS), bed turnover, infection rates, and mortality.

Predictive Risk Scoring

Machine learning algorithms flagging sepsis risk and 30-day hospital readmission.

Structured Phase-by-Phase Syllabus

Focus on build-by-doing milestones rather than passive video consumption.

Weeks 1 - 4

Phase 1: Healthcare Relational Data & SQL Queries

Healthcare data architectures: EHR, Laboratory Information (LIS), Radiology (PACS), and Claims engines
Writing advanced SQL queries on patient encounters, medication orders, and ICD-10 diagnostic codes
HL7 v2 messages and modern FHIR JSON resource standards (Patient, Encounter, Observation)

🎯 Milestone Proof Project: Build a Multi-Table SQL Database Query analyzing patient length of stay and medication costs on MIMIC-IV dataset.

Weeks 5 - 8

Phase 2: Clinical Quality Dashboards & Claims Analytics

Building hospital executive dashboards in Power BI: Bed occupancy, ER wait times, and infection metrics
Healthcare insurance claims analysis: Denial rate calculation, medical loss ratio (MLR), and fraud detection
Quality metrics: HEDIS measures, NABH clinical indicators, and hospital-acquired infection (HAI) tracking

🎯 Milestone Proof Project: Create an Executive Hospital Clinical Performance & Bed Occupancy Power BI Dashboard.

Weeks 9 - 12

Phase 3: Predictive Clinical Analytics in Python

Exploratory data analysis on electronic health records with Python Pandas and Seaborn
Predictive classification modeling: Predicting 30-day heart failure readmission risk using Logistic Regression & XGBoost
HIPAA compliance, patient data de-identification (Safe Harbor method), and DPDP guidelines

🎯 Milestone Proof Project: Train and evaluate a Machine Learning model predicting patient hospital readmission risk.

Technical Interview Questions & Answers

Q1: What is FHIR and why is it replacing legacy HL7 v2 for healthcare data exchange?

FHIR (Fast Healthcare Interoperability Resources) is a modern, web-based standard created by HL7. It utilizes modular RESTful APIs and standardized JSON/XML data formats (e.g. Patient, Condition, Observation resources), making EHR data integration significantly faster and easier for mobile apps and cloud analytics compared to legacy pipe-delimited HL7 v2 messages.
