Observational Health Data Sciences and Informatics

Conditions are records of a Person suggesting the presence of a disease or medical condition stated as a diagnosis, a sign or a symptom, which is either observed by a Provider or reported by the patient. Conditions are recorded in different sources and levels of standardization, for example:

• Medical claims data include diagnoses coded in ICD-9-CM that are submitted as part of a reimbursement claim for health services and procedures.

• EHRs may capture Person Conditions in the form of diagnosis codes or symptoms.
