Dataset Card for MRRANK Data

Dataset Description

Dataset Summary

The MRRANK data is a component of the UMLS (Unified Medical Language System) Metathesaurus, available in the Rich Release Format (RRF). This dataset contains information about the ranking of concept names within the Metathesaurus, providing a hierarchical structure based on source vocabulary and term type. It supports developers and researchers in determining the preferred terms and their order of precedence for various medical concepts.

Purpose

The MRRANK dataset serves to establish a numeric order of precedence for concept names in the UMLS Metathesaurus. This ranking is crucial for ensuring that the most appropriate terms are selected for display and use in medical informatics applications, clinical decision support systems, and other health-related software solutions.

Column Descriptions

RANK

• Description: Indicates the numeric order of precedence for a concept name. Higher values indicate higher precedence.
• Values: Numeric values, where a higher value means the term has a higher priority for display and use. For example, a value of 0624 indicates a high precedence.

SAB (Source Abbreviation)

• Description: The abbreviated name of the source vocabulary from which the term is derived. Each source abbreviation can be either a Root Source Abbreviation (RSAB) or a Versioned Source Abbreviation (VSAB).
• Values: Alphanumeric strings with a maximum length of 20 characters, such as MSH or SNOMEDCT_US. Each value represents an abbreviated source name without version information (RSAB) or with version information (VSAB).

TTY (Term Type)

• Description: The abbreviation for the term type in the source vocabulary. Term types define the role or nature of the term within the source vocabulary.
• Values: Alphanumeric strings, such as PN for Metathesaurus Preferred Name or CD for Clinical Drug. Possible values are listed in the Abbreviations Used in Data Elements page.

SUPPRESS

• Description: Indicates the suppressible status of all atoms (names) with the given Source and Term Type (SAB/TTY). This field reflects the NLM-recommended suppressibility.
• Values: Y or N, where Y indicates that the term type should be suppressed and N indicates that it should not be suppressed. The status E does not occur in this field.

Example Record

RANK:      0624
SAB:       MSH
TTY:       PN
SUPPRESS:  N

Usage

This dataset is primarily intended for developers and researchers working on medical informatics applications. It can be used to determine the preferred terms for medical concepts based on their ranking, support clinical decision-making, and enhance health information systems by ensuring the most appropriate terms are used.
