CCC (Clinical Care Classification) - Metathesaurus Representation


This page lists UMLS Metathesaurus data elements and traces them back to the specific source data that populates them.

Skip to: Atoms, Attributes, Definitions, Relationships, Mappings

VSAB: CCC2_5_2018

Summary of Changes

File format: In collaboration with Dr. Virginia Saba, the NLM developed a simplified file format for UMLS source processing. The files reflect content changes, but there is no change to the data elements as compared to CCC2_5. These files will be available at http://www.sabacare.com in both Excel and delimited text format. Contact Dr. Saba for access information.

Metathesaurus soruce processing: SCUIs are no longer assigned due to ambiguity. Relationships are attached to AUIs rather than SCUIs.

Files:

File Name Description
action_modifiers.txt Action Types to expand the scope of the Intervention
care_components.txt Classify the CCC Terminologies
diagnoses.txt Nursing diagnoses/problems
interventions.txt Core nursing interventions
outcome_qualifiers.txt Expected or actual outcome qualifiers

Identifiers:


Identifiers are assigned as follows:

CODE:
Concept type TTY CODE
Components HT Component Letter Code
Diagnoses PT Diagnosis Code (includes Component Letter Code)
Interventions PT Intervention Code (includes Component Letter Code)
Modifiers MP Action Modifier or Outcome Qualifier Code
Types HT Two "type" atoms are created for hierarchy purposes during UMLS source processing to categorize Interventions and Diagnoses. CODE = MTHU000001 and MTHU000002, respectively

SAUI: Not applicable
SCUI: Not applicable
SDUI: Not applicable

Atoms (MRCONSO):


Term Type Description Origin
HT
Hierarchical Term (Component) CODE: Component Letter
STR: Component Name
MP Modifier CODE: Action Modifier or Outcome Qualifier Code
STR: Modifier or Qualifier Name
MTH_HT MTH Hierarchical Placeholder Term CODE: MTHU# assigned during Metathesaurus source processing
STR: "Interventions" or "Diagnoses"
Created to separate Intervention and Diagnoses sections of hierarchy
PT Preferred Term (Diagnosis or Intervention) Diagnosis or Intervention Code (includes Component Letter)
STR: Diagnosis or Intervention Name

Attributes (MRSAT):


No attributes are included for CCC



Definitions (MRDEF):

Definitions are created from data in the "Definition/Description" fields.


Relationships (MRREL):


REL RELA
inverse_RELA
Origin
AQ
QB
actual_outcome_of
has_actual_outcome
Connects Outcome Qualifiers to Diagnoses to to code the "actual outcome" (past tense)
AQ
QB
expected_outcome_of
has_expectted_outcome
Connects Outcome Qualifiers to Diagnoses to to code the "expected outcome" (present tense)
AQ
QB
modifies
modified_by
Connects Action Modifiers to Interventions. Used to modify a CCC Intervention concept to build a CCC Intervention Action concept

Mappings (MRMAP):

No relationships to other sources are processed for CCC.
