Methods of Documentation II: POMR

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.

Taxonomy

Taxonomy

Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Anatomical Terminology

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,...

Methods of Documentation I: Source-Oriented Records

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

This summary is machine-generated.

A new ontology, Variation Ontology (VariO), standardizes genetic and non-genetic variation data. This enables efficient computational analysis and integration for genotype-phenotype relationship discovery.

Area of Science:

Genomics
Bioinformatics
Molecular Biology

Background:

Systematic representation of genetic and non-genetic variations is crucial for large-scale studies and data integration.
Existing variation data often lacks systematic organization, hindering its effective use.
Discovering novel genotype-phenotype relationships requires standardized data formats.

Purpose of the Study:

To introduce the Variation Ontology (VariO) for annotating the effects, consequences, and mechanisms of biological variations.
To provide detailed instructions and examples for making VariO annotations.
To facilitate computational analysis and data integration of variation information.

Main Methods:

Development of the Variation Ontology (VariO) with hierarchical levels for DNA, RNA, and protein variations.
Annotation of variation type, function, structure, and property across molecular levels.
Formalization of existing knowledge about variations and their effects for computational efficiency.

Main Results:

The Variation Ontology (VariO) provides a structured framework for annotating variation data.
Annotations are made relative to normal states, including reference sequences and wild-type properties.
VariO facilitates the summarization and formalization of variation knowledge.

Conclusions:

Detailed guidelines and examples are provided for using VariO to annotate variations and their effects.
A dedicated annotation tool is available and will be enhanced to include evidence.
VariO is adaptable for various databases, promoting consistent annotation across different data repositories.
