Overview

Description

Introduction to BMI120
BMI120 is an introductory course in biomedical informatics, focusing on the intersection of healthcare, data science, and technology. It covers fundamental concepts like electronic health records (EHRs), clinical decision support, data standards (e.g., HL7, FHIR), and healthcare analytics. Students learn how informatics improves patient care, research, and public health through data-driven approaches.
Key topics include:
- Basics of medical terminologies and coding systems (e.g., ICD, SNOMED).
- Principles of health IT, interoperability, and data security (HIPAA compliance).
- Applications of AI/machine learning in healthcare.
The course is ideal for students pursuing careers in healthcare, bioinformatics, or health IT, blending theoretical knowledge with practical skills. No advanced technical background is required, making it accessible to beginners.
