What is Health Informatics?

Health Informatics is the interdisciplinary field that uses information technology, data science, and healthcare knowledge to optimize the collection, storage, retrieval, and use of health data for improving patient care, research, and public health.

Core Components

  • Electronic Health Records (EHRs): Digital versions of patients’ paper charts.
  • Clinical Decision Support Systems (CDSS): Tools that analyze data to help healthcare providers make decisions.
  • Telemedicine: Remote diagnosis and treatment using telecommunications.
  • Health Information Exchange (HIE): Sharing health data across organizations.
  • Personal Health Records (PHRs): Health data maintained by individuals.

Key Functions

Function Description
Data Collection Gathering patient and clinical data
Data Storage Securely saving health information
Data Analysis Using algorithms to find patterns and insights
Communication Sharing information among providers and patients
Decision Support Assisting clinical decisions with evidence-based tools

Surprising Facts

  1. AI Diagnoses Faster Than Doctors: In some cases, artificial intelligence systems can diagnose diseases like diabetic retinopathy more accurately and quickly than human experts.
  2. Wearables Generate Billions of Data Points: A single hospital’s wearable devices can produce billions of data points per year, enabling real-time monitoring and predictive analytics.
  3. Blockchain Secures Patient Data: Some hospitals use blockchain technology to ensure the integrity and privacy of patient records, making unauthorized data tampering nearly impossible.

Interdisciplinary Connections

  • Computer Science: Algorithms, databases, cybersecurity, machine learning.
  • Medicine: Clinical workflows, diagnostics, patient care.
  • Statistics: Biostatistics, epidemiology, predictive modeling.
  • Ethics & Law: Patient privacy (HIPAA), data consent, digital rights.
  • Engineering: Medical device integration, sensor technology.
  • Public Health: Disease surveillance, population health management.
