ICEnAXES ICEnAXES EMS & Wilderness Emergency Care Training DKA Diabetic ketoacidosis occurs primarily in patients with type 1 diabetes. The incidence is roughly 2 episodes per 100 patient years of diabetes, with about 3% of patients with type 1 diabetes initially presenting with diabetic ketoacidosis. It can occur in patients with type 2 diabetes as well; however, this is less common. Diabetic ketoacidosis occurs primarily in patients with type 1 diabetes.
