I want to find all patients with an admission diagnosis of acute kidney failure and chronic kidney disease (ICD codes N17-N19) in the Diagnoses section of the dataset. The query will have a specificity scale of 0, meaning all matches are considered equally important, and a total item occurrence of 1, meaning only one instance of the condition is required for the patient to be included in the results. The query will have an accuracy scale of 100, indicating a high level of confidence in the results, and the panel timing is set to ANY, meaning the diagnosis can occur at any time during the patient's stay. The query will search for this condition in the ICD10_ICD9 section of the dataset, and the class is set to ENC (Encounter). The query will not be synonymous with any other items, and the applied path is restricted to diagnoses of diseases in the genitourinary system (N0-N9).
