Summary of “Unit 1: What is Health Informatics? Lecture A”
This lecture provides an introductory overview of health informatics, focusing on defining key concepts, exploring the scope of biomedical and health informatics, and highlighting current drivers and trends in the field. The content is structured around definitions, theoretical foundations, subfields, and the role of informatics in improving healthcare delivery.
Main Ideas and Concepts
1. Introduction to Health Informatics
Health informatics is the interdisciplinary field that applies information science and technology to healthcare. The lecture covers:
- Definitions of information management, information technology, and informatics.
- The fundamental theorem of informatics.
- Biomedical and health informatics as fields of study.
- Major application areas of biomedical informatics.
- Current drivers and trends influencing health informatics.
2. Definitions
-
Information Management (AHIMA): The processes of generating, collecting, organizing, validating, analyzing, storing, integrating, disseminating, communicating, and safeguarding data and information.
-
Information System/Technology (AHIMA): Automated computer-based systems that record, manipulate, store, recover, and disseminate data.
-
Health Information Technology (HIT) (US Dept. of Health and Human Services): Application of computer hardware and software for storage, retrieval, sharing, and use of healthcare information to support communication and decision-making.
-
Informatics (Bernam, Smith, Johnson): The science of information, where information is data with meaning; focuses on optimal use of meaningful data.
-
Data-Information-Knowledge-Wisdom (DIKW) Hierarchy:
- Data: Raw facts and symbols.
- Information: Processed data providing answers to who, what, when, where.
- Knowledge: Interpretation of information answering how.
- Wisdom: Evaluated understanding answering why.
3. Fundamental Theorem of Informatics (Dr. Friedman)
A person working with an information resource (e.g., computer system) performs better than the person alone. The interaction between human and information resource is key and is shaped by context.
4. Applications and Domains of Informatics
Informatics applies to many fields; this lecture focuses on healthcare.
Two key definitions of biomedical informatics:
-
AMIA: Interdisciplinary field studying effective use of biomedical data for scientific inquiry, problem solving, and decision-making to improve health.
-
Shortlith and Bly: Scientific field dealing with biomedical information and knowledge for problem-solving and decision-making.
5. Health Informatics
- Often used interchangeably with biomedical informatics but typically refers to applied research and practice in clinical and public health domains.
- Requires standards for data collection, organization, maintenance, and exchange.
6. Subfields of Biomedical Informatics (Shortlith and Bly)
-
Public Health Informatics: Population and society focus; applications include disease surveillance systems, immunization registries, homeland security.
-
Clinical Informatics: Individual patient care focus; applications include electronic medical records (EMRs), clinical decision support.
-
Imaging Informatics: Focus on acquisition, storage, and analysis of medical images; examples include CT scanners and PACS.
-
Bioinformatics: Molecular and cellular level; applications include genomic sequencing.
7. Component Sciences in Biomedical Informatics
Biomedical informatics is interdisciplinary, involving:
- Computer science
- Clinical science
- Basic biomedical science
- Cognitive science
- Bioengineering
- Management science
- Epidemiology
- Statistics
8. Drivers and Trends in Health Informatics
-
Legislative Drivers:
- American Recovery and Reinvestment Act (ARRA) 2009, especially the Health Information Technology for Economic and Clinical Health (HITECH) Act, providing funding and incentives for health IT adoption.
-
Technological Trends:
- Growth of e-health (use of ICT in health for treatment, research, education, disease tracking).
- Adoption of Electronic Medical Records (EMRs) — digital records within a single healthcare organization.
- Implementation of Electronic Health Records (EHRs) — interoperable records across multiple organizations.
- Health Information Exchange (HIE) — secure electronic sharing of health information among organizations to support coordinated care.
9. Connection Between Informatics and Healthcare Improvement
- Informatics supports cost-effective, high-quality, and safe patient care.
- Enables improved healthcare delivery through technology such as telemedicine and integrated health records.
