Health informatics integrates healthcare, information technology, and data science to improve , public health, and healthcare operations.

Context: Health Informatics Definition and Purpose

draws from medicine, computer engineering/software, data science, information systems, organizational change, and public health.

Context: Multidisciplinary Foundations of Health Informatics

EHRs (Electronic Health Records) are digital systems for storing and sharing patient data to support continuity of .

Context: Electronic Health Records (EHRs)

EHRs must with labs, imaging, and pharmacies so data can be exchanged and interpreted correctly.

Context: Interoperability

tools help clinicians make evidence-based decisions using algorithms and patient data.

Context: Clinical Decision Support (CDS)

CDS depends on accurate patient data from .

Context: CDS depends on EHR data

Clinical decision support using algorithms and patient data causes which leads to improved patient safety.

Context: Cause→Effect: CDS → Evidence-based decisions → Patient safety

Interoperability across EHRs, labs, imaging, and pharmacies causes more effective analytics and coordinated care by enabling consistent data exchange for .

Context: Cause→Effect: Interoperability → Analytics/AI inputs → Coordinated care

Use of big data, AI, and machine learning causes earlier risk prediction and improved treatment planning through models that identify trends and predict risks.

Context: Cause→Effect: Big data/AI/ML → Risk prediction → Treatment planning

Remote healthcare delivery (telehealth/telemedicine) causes improved access to care, especially for chronic disease management, because patients can receive services without geographic .

Context: Cause→Effect: Telehealth → Access improvement via reduced geographic barriers

ensures different systems can exchange and interpret data correctly.

Context: Interoperability definition

Health Data Analytics and AI uses big data, AI, and machine learning to identify trends, predict , and personalize care.
