Given a patient who presents with polyuria and/or polydipsia, the candidate will diagnose the cause, severity, and complications, and will initiate an appropriate management plan.
Given a patient with polyuria and/or polydipsia, the candidate will
- list and interpret critical clinical findings, including
- diagnose polyuria/polydipsia, causal factors, and severity, differentiating urinary frequency from polyuria;
- inquire about any personal or family history of diabetes;
- identify neurological features that may suggest intracranial pathology as a cause of central diabetes insipidus;
- list and interpret critical investigations, including
- tests which distinguish between water and osmotic diuresis;
- screening for diabetes;
- use of a voiding diary, when appropriate;
- construct an effective initial management plan, including
- management of the underlying cause;
- determination as to whether the patient requires specialized care.
