I want to find all patients with an Admit Diagnosis of Coagulation defects, specifically Defibrination syndrome, within the Hematologic diseases category (ICD-9 codes 280-289). The query is designed to have a specificity scale of 0, meaning it will return all patients with this diagnosis regardless of its relevance to their primary condition, and the accuracy scale is set to 100, indicating that all results should be included. The query timing is set to ANY, meaning it will include patients regardless of when they were admitted.
