Summary
Health informatics integrates health data with technology to improve patient outcomes through a cycle of data creation, storage, analysis, and application.
Key Points
- Health informatics serves as the interface between health and technology, using patient data to enhance healthcare outcomes.
- The data lifecycle consists of four steps: creation, storage in EHRs, analysis, and dissemination of results to providers.
- Patient information—including symptoms, diagnoses, treatments, and personal details—is recorded by professionals or smart sensors and stored in Electronic Health Record (EHR) systems.
- Advanced analytics, machine learning, and artificial intelligence are applied to EHR data to uncover patterns and make predictive assessments.
- Informatics can assess and predict risks for diseases such as anemia and diabetes, and can detect previously undiagnosed substance use.
- Predictive models can estimate a patient’s likelihood of readmission within 30 days and forecast reactions to specific medications.
- Health informatics extends beyond hospitals to administrative settings and personal health apps, exemplified by the concept of "prescribing an app."
- Mobile and fitness apps enable individuals to track health metrics, providing valuable data for both patients and clinicians.
- George Mason University offers health informatics programs that combine theoretical learning with hands‑on experience in clinics and research.
- Graduates from these programs are prepared to drive innovation and shape the future of the healthcare industry.
