| ===== Mapping of Concepts ===== | ===== Mapping of Concepts ===== | ||
| + | * **Mapping**, also known as **a map**, is an association between a particular concept in one code system or | ||
| + | * dataset and code in another, rarely the same, code system that has the same (or similar) meaning. | ||
| + | * Also, **Mapping** is the process to transform one concept into a Standard one. The Standardized Clinical Data Tables allow only Standard Concepts, thus all other codes used in the source databases have to be translated to Standard Concepts. | ||
| + | * Mapping is done through records in the CONCEPT_RELATIONSHIP table. They connect each Concept to a Standard Concept through a number of special relationship_id: | ||

| + | * If there are 2 or more similar Standard concepts in the OMOP vocabulary, please, report about it at the [[https://forums.ohdsi.org/c/vocabulary-users|OHDSI Forum]] and unless it is fixed, as the first-line choice, use LOINC for Measurements and SNOMED for everything else. | ||
| + | * If there are 2 similar Standard concepts within SNOMED, look at the domain (Morphologic abnormality is an Observation, Clinical finding is a Condition), revise attributes and hierarchy of both concepts (its number, fullness, and correctness). It is not necessary to compare the amount of relationships/children precisely, just verify that all seems appropriate and the hierarchy is rich enough. If it does for both concepts, then choose concepts belonging to SNOMED International (short concept codes) rather than SNOMED US/UK Editions (long concept codes). If the length of concept codes is identical, then choose the one with a smaller number of concept_id. | ||

But in order to maintain the ability to retrieve these Concepts when searching using hierarchical Concepts, two or more mappings are provided instead. |
| - | {{ :documentation:vocabulary:diabetesmapping.png?nolink |Mapping of ICD10 E10.0}} | + | For example, in ICD-10-CM diabetic complications are a part of the disorder of Diabetes Mellitus, while in SNOMED Diabetes Mellitus and its complications reside in distinct hierarchical branches. |
| - | The target hierarchy in SNOMED has a different topology to the organizational structure in ICD10. Here, type 1 (insulin-dependent, E10) and type 2 (insulin-independent, E11) diabetes are the primary distinctive features. The combination of type 2 diabetes with its combination coma E11.0 defines type 2 diabetes with its complication coma. In SNOMED, diabetic complications has its own hierarchy, which branches into the Concept of diabetes with coma, or type 1 or 2 diabetes with complication. On the next level the distinctive forms of coma (hypoglycemic, hyperosmolar and ketoacidotic) are distinguished. However, there is no combination of diabetes type 2 with coma. | + | {{ :documentation:vocabulary:5_-_diabetes-related_case_3_.png?400 |}} |
| - | The solution is to map E11.0 to both 44054006 Type 2 diabetes mellitus and 420662003 Coma associated with diabetes mellitus. Even though there is no distinct equivalent in SNOMED, hierarchical queries for either diabetes 2 in combination with coma will retrieve the correct records. | + | As another example, ICD-10 codes indicating complications of pregnancy are in the chapter of "Pregnancy, childbirth and the puerperium" that has a semantic relation to the fact of pregnancy, while in SNOMED denoting pregnancy conditions and their complications are in the separate hierarchical branches. |
| - | === Rules for Condition Mapping === | + | {{ :documentation:vocabulary:6_-_pregnancy-related_case_1_.png?400 |}} |
| - | In general, Conditions are records suggesting the presence of a disease or medical condition stated as a diagnosis, a sign or a symptom. However, there are a lot of conditions that are not originating in the biological function of the human body, but still require medical attention. Or they are true Conditions, but not at the time of the recording (History of) or in the person itself (Family history of). The mapping rules for these are as follows: | + | |
| + | The solution for both examples is to map Non-standard concepts to several standard ones. Even though there is no distinct equivalent in SNOMED, hierarchical queries will retrieve the correct records. | ||
