I want to find patients who have had a diagnosis related to the circulatory system (ICD-9 codes 390-459) as either their Admit Diagnosis, Principal Diagnosis, or Secondary Diagnosis, within the same visit. The specificity scale is set to 0, meaning the diagnosis could be present at any level of specificity, and the accuracy scale is set to 100, indicating a high level of confidence in the query results. The query will search for these diagnoses in the i2b2 Diagnoses module, and the results will be displayed in three panels.
