Data Collection by Observations01:08

Data Collection by Observations

11.9K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Methods of Documentation V: CBE

891
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...

Methods of Documentation VI: Case Management Model

564
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Area of Science:

  • Biomedical Informatics
  • Data Science
  • Health Data Management

Background:

  • Common Data Models (CDMs) are crucial for data exchange and integration, but transforming local data is resource-intensive.
  • Existing methods often lack flexibility and scalability when adapting to new data sources or updating models.
  • The Observational Medical Outcomes Partnership (OMOP) CDM is widely adopted, but tools are often OMOP-specific.

Purpose of the Study:

  • To compare the ontology-based OntoBridge tool with traditional ETL methods for converting local datasets into CDMs.
  • To evaluate flexibility, scalability, and reusability in managing data sources, CDM updates, and adopting new CDMs.
  • To assess the efficiency of OntoBridge versus traditional ETL in the context of OMOP CDM adoption.

Main Methods:

  • Comparative analysis of OntoBridge and traditional ETL processes for CDM conversion.
  • Evaluation of adaptability to new data sources and Common Data Model (CDM) updates.
  • Assessment of scalability in adopting various CDMs, including OMOP and i2b2.

Main Results:

  • OntoBridge demonstrated superior flexibility in integrating new data sources and adapting to Common Data Model (CDM) updates.
  • OntoBridge proved more scalable, enabling the adoption of diverse CDMs like i2b2.
  • Traditional ETL methods showed limitations, often relying on OMOP-specific tools and OHDSI development.

Conclusions:

  • OntoBridge offers a more flexible, scalable, and maintenance-efficient alternative to traditional ETL for Common Data Model (CDM) data integration.
  • Ontology-based approaches can enhance the adaptability and reusability of data transformation processes.
  • The findings suggest OntoBridge can facilitate broader adoption of various CDMs beyond OMOP.
