Methods of Documentation I: Source-Oriented Records

1.7K
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:

Positron Emission Tomography01:29

Positron Emission Tomography

6.9K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Anatomical Terminology01:20

Anatomical Terminology

25.6K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Schemas01:42

Schemas

12.3K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Area of Science:

  • Medical Informatics
  • Clinical Terminology
  • Natural Language Processing

Background:

  • Standardized terminologies like SNOMED CT and Solor are crucial for knowledge management and clinical decision support (CDS).
  • Semantic relations within these terminologies provide explicit meaning for compositional expressions, aiding various healthcare informatics tasks.

Purpose of the Study:

  • To identify semantic relations absent or underdeveloped in SNOMED CT and Solor.
  • To integrate these identified relations with existing terms to form data triples for enhanced knowledge representation.

Main Methods:

  • Identified critical semantic relations not fully present in SNOMED CT or Solor, specifically for VA Knowledge Artifacts (KNARTS).
  • Formed triples using identified relations and existing terms.
  • Implemented these relations within the High Definition-Natural Language Processing (HD-NLP) program and Solor HD-NLP server for tagging KNARTS.

Main Results:

  • A total of 38 novel semantic relations were identified and implemented.
  • Use cases were developed for each relation and integrated into the Solor HD-NLP server.
  • The new relations were successfully used for tagging KNARTS.

Conclusions:

  • The newly identified SNOMED CT and Solor semantic relations enable clinicians to add greater detail and meaning to clinical notes.
  • Enhanced clinical notes can improve the accuracy and effectiveness of triggering clinical decision support (CDS) rules.
  • This advancement has the potential to significantly improve CDS provided to clinicians during patient care.
