 We will implement an EHR-based intervention at UCSF to predict which patients are at high risk of inpatient hypoglycemia and take action to prevent the hypoglycemic event. In real time, all adult non OB patients with a glucose 90, and a high risk of future hypoglycemia based on the WSL formula will be identified. Patients will be randomly assigned to intervention or no intervention current standard care. The intervention will consist of an automated provider alert with recommendations on what adjustments could be made to avoid a potentially serious hypoglycemic event.
