This page lists UMLS Metathesaurus data elements and traces them back to the specific source data that populates them.
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.
|action_modifiers.txt||Action Types to expand the scope of the Intervention|
|care_components.txt||Classify the CCC Terminologies|
|interventions.txt||Core nursing interventions|
|outcome_qualifiers.txt||Expected or actual outcome qualifiers|
Identifiers are assigned as follows: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|
||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
|Connects Outcome Qualifiers to Diagnoses to to code the "actual outcome" (past tense)|
|Connects Outcome Qualifiers to Diagnoses to to code the "expected outcome" (present tense)|
|Connects Action Modifiers to Interventions. Used to modify a CCC Intervention concept to build a CCC Intervention Action concept|
