Summary
Standardizing data through Common Data Elements (CDEs) is crucial for biomedical research. The CEDAR Workbench platform simplifies CDE creation and sharing, enabling easier data interoperation and reuse across systems.
Area of Science:
- Biomedical Informatics
- Data Standardization
- Metadata Management
Background:
- Biomedicine requires aggregating data from diverse healthcare and research sources.
- Standardizing data capture and reporting is essential for data interoperation.
- Common Data Elements (CDEs) are key for data standardization but lack universal exchange formats.
Purpose of the Study:
- To develop a platform simplifying the creation, exchange, and use of CDEs.
- To address limitations in current CDE systems, including lack of interoperability and heavyweight architecture.
- To facilitate the reuse of CDEs across different systems and applications.
Main Methods:
- Extended the CEDAR Workbench metadata management system.
- Developed functionalities for simplified CDE definition and sharing.
- Integrated a large CDE library from the National Cancer Institute's caDSR system.
Main Results:
- The CEDAR Workbench platform enables rapid CDE creation and sharing.
- Users can immediately deploy Web-based forms using defined CDEs for metadata acquisition.
- National Cancer Institute's caDSR CDEs are now publicly available through the platform.
Conclusions:
- The CEDAR Workbench provides a lightweight, accessible platform for CDE management.
- Facilitates seamless data interoperation and reuse in biomedical research.
- Enhances the adoption and application of standardized data elements in healthcare and research.

01:23Methods of Documentation V: CBE
1.3K
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

01:24Data Reporting and Recording
5.3K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:14Design Example: Managing Concrete Workability
231
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.

01:30Impact of Schemas
154
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the...

01:25Workability of Concrete
293
The workability of concrete is a crucial property that affects its handling, placing, and finishing during construction. It describes the ease with which concrete can be mixed, placed, compacted, and finished. Workability is primarily concerned with the concrete's movement and its ability to resist internal friction and external resistance from molds and reinforcements during the application process.
Concrete's workability is determined by its resistance to internal forces that arise...
