Description
Familial risk criteria for common cancers rely on the age of cancer onset, which is documented inconsistently using structured and unstructured formats in electronic health records (EHRs). We operationalized a natural language processing (NLP) system to extract disease onset information from free-text EHR fields with recall and precision ranging from 98% to 100%.
Learning Objective: Understand the age of onset data type of FHIR's FamilyMemberHistory resource.
Learn how and how well the rule-based NLP can be used to extra the age of cancer onset of family members from the free text comments field.
Learn how NLP generated information can be mapped into FHIR data types for information exchange or downstream data analyses.
