Summary
Biomedical informatics integrates information to improve decision-making. Three generations of integration projects show a continuum of progress in workflow, structure, and data extraction.
Area of Science:
- Biomedical Informatics
- Health Informatics
- Information Science
Background:
- The integration of diverse information sources is a fundamental goal in biomedical informatics.
- Technological advancements and informatics discoveries have shaped the evolution of information integration strategies.
- Previous integration approaches continue to be relevant alongside newer methodologies.
Purpose of the Study:
- To review and categorize distinct generations of information integration projects in biomedical informatics.
- To analyze the evolution of integration concepts based on technological and scientific progress.
- To identify the enduring principles across different integration project generations.
Main Methods:
- Literature review of information integration projects in biomedical informatics.
- Categorization of projects into three distinct generations based on their approach.
- Analysis of the progression and relationship between different integration strategies.
Main Results:
- Identification of three generations of information integration projects: single-purpose databases, enterprise information architecture, and inter-related disparate sources.
- Demonstration that earlier integration concepts are not obsolete but form a continuum with newer approaches.
- Key dimensions of progress identified as workflow, structure, and extraction.
Conclusions:
- Information integration in biomedical informatics has progressed through distinct, yet interconnected, generational approaches.
- The principles of workflow, structure, and extraction provide a framework for understanding this continuum.
- Future integration efforts can build upon the foundational ideas from all three generations.

01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
01:15Activation of Integrins
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.

01:18Independent and Dependent Sources
In electrical circuits, sources play a crucial role in providing power for the operation of the circuit. These sources can be broadly categorized into two types: independent and dependent.
Independent voltage or current sources supply a fixed amount of voltage or current, respectively, which is unaffected by other elements within the circuit. These are represented using specific symbols. Independent voltage sources are symbolized with polarities (+ and -), indicating the direction of the...
