This page lists UMLS Metathesaurus data elements and traces them back to the specific source data that populates them.
VSAB: CCC2_5_2018
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 source processing: SCUIs are no longer assigned due to ambiguity. Relationships are attached to AUIs rather than SCUIs.
| 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 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 |
| 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 |
| REL | RELA inverse_RELA |
Origin |
|---|---|---|
| AQ QB |
actual_outcome_of has_actual_outcome |

| AQ QB |
expected_outcome_of has_expectted_outcome |
Connects Outcome Qualifiers to Diagnoses to to code the "expected outcome" (present tense) |
| AQ QB |
