Summary
Medical data element repositories need improvement for broader use. Analysis reveals issues in data reuse protocols and FAIR principle compliance, hindering effective medical data sharing and interoperability.
Area of Science:
- Medical Informatics
- Data Science
- Health Data Management
Background:
- Data element repositories are crucial for standardizing medical data and enhancing semantic interoperability.
- Current applications of these repositories are often limited to specific projects and institutions.
Purpose of the Study:
- To identify challenges and promote wider adoption of medical data element repositories.
- To evaluate typical repositories to understand their strengths and weaknesses.
Main Methods:
- A literature review identified five data element repositories for analysis.
- A novel framework with 7 dimensions and 36 indicators was developed for evaluation.
Main Results:
- Repositories exhibit unique characteristics but face construction issues, including lack of data reuse protocols and insufficient application information.
- FAIR principle compliance: 45% for Findable/Reusable, 90% for Accessible, 67% for Interoperable.
Conclusions:
- Recommendations are provided to enhance repository construction and application.
- These insights benefit data managers, computer experts, and stakeholders in medical data sharing.

825
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

01:18Methods of Documentation I: Source-Oriented Records
1.1K
Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

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,...

01:16Bioequivalence: Overview
935
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

Documentation is the systematic process of formally recording, maintaining, and communicating information.
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...
