I want to find all patients with a diagnosis of Mental Disorders (ICD codes 290-319) recorded as their Admit Diagnosis, with no specific time frame applied, and a specificity scale of 0, meaning any occurrence of the diagnosis will be included, and an accuracy scale of 100, indicating high confidence in the results. The query will be applied to panel 1, and only one item will be included. The query will not be synonymous with any other items.
