Classification of Illness01:17

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe and...

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Methods of Documentation VI: Case Management Model

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 illness...
Genomics02:02

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Anatomical Terminology01:20

Anatomical Terminology

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,...

Area of Science:

  • Biomedical Informatics
  • Knowledge Representation

Background:

  • Clinical data requires machine-processable formats for research.
  • Manual annotation is time-consuming.
  • Automated methods like Natural Language Processing (NLP) have limitations in data quality.

Purpose of the Study:

  • To introduce Semantator, a semi-automatic tool for annotating clinical documents with Semantic Web ontologies.
  • To improve the efficiency and quality of clinical data annotation.
  • To leverage Semantic Web standards for enhanced data representation and reasoning.

Main Methods:

  • Semantator allows manual creation/deletion of ontology instances and property linking.
  • It integrates with the NCBO annotator and cTAKES for automatic annotation.
  • Annotations are represented using Semantic Web standards.

Main Results:

  • Semantator facilitates semi-automatic document annotation with ontologies.
  • The tool supports reasoning capabilities based on owl:disjointWith and owl:equivalentClass.
  • User experiences with Semantator are discussed.

Conclusions:

  • Semantator offers a hybrid approach to clinical data annotation, balancing automation and manual control.
  • The use of Semantic Web standards enhances data interoperability and analytical potential.
  • The tool aims to improve the reliability of automatically extracted clinical data.
