Naturalistic Observations02:30

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Methods of Documentation II: POMR

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.
Observational Studies01:11

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One example of...
Obedience01:08

Obedience

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation, obedience...

Methods of Documentation IV: Focus Charting

Focus Charting, also known as the focus charting system or "focus documentation," is a systematic documentation approach used in healthcare to organize patient information in medical records.
It typically involves three columns for recording information:

Methods of Documentation I: Source-Oriented Records

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:

Summary

Researchers analyzed operative notes to improve information extraction (IE). They found existing resources lack surgical action vocabulary, highlighting the need for specialized semantic tools for better IE from medical reports.

Area of Science:

  • Medical Informatics
  • Natural Language Processing
  • Computational Linguistics

Background:

  • Operative notes contain valuable procedural details.
  • Effective information extraction (IE) from these notes is crucial for research and clinical applications.
  • Current IE techniques may be limited by the specialized language used in surgical reports.

Purpose of the Study:

  • To investigate the sublanguage of action verbs within the 'procedure description' section of operative notes.
  • To identify coverage gaps in existing lexical and semantic resources for surgical actions.
  • To inform the development of improved IE systems for operative reports.

Main Methods:

  • Utilized deep parsing on a large corpus of 362,310 operative notes.
  • Employed an expanded Stanford parser and the SPECIALIST Lexicon.
  • Collected nominal action predicates from multiple lexical and semantic databases (WordNet, UMLS, etc.).

Main Results:

  • Identified 200 verbs, including 147 action verbs, with 92% coverage of the operative report 'procedure description' section.
  • Discovered significant coverage gaps in existing resources like the UMLS Metathesaurus, SPECIALIST Lexicon, WordNet, and FrameNet.
  • Demonstrated the inadequacy of current resources for capturing the full spectrum of surgical actions.

Conclusions:

  • Existing lexical, domain, and semantic resources are insufficient for comprehensive IE from operative notes.
  • There is a clear need to develop surgical domain-specific semantic resources.
  • Such resources are essential for advancing the accuracy and effectiveness of information extraction from surgical procedure descriptions.
