I want to find patients with a diagnosis of Essential (primary) hypertension (ICD10-ICD9 code I10) and Diabetes mellitus (ICD10-ICD9 code E08-E13) at any time during their medical history, with a specificity scale of 0 and an accuracy scale of 100 for each panel. The query is named "Essenti-Diabete@20:34:54" and will include two panels, one for each condition. The first panel will focus on Essential (primary) hypertension under the category of Diseases of the circulatory system, while the second panel will focus on Diabetes mellitus under the category of Endocrine, nutritional and metabolic diseases. The query will not be inverted, meaning it will return patients who have both conditions, and the total number of occurrences for each item is set to 1. The query will return results for patients who have been diagnosed with both conditions.
