Misdiagnosis and Diabetic Ketoacidosis at Diagnosis of Type 1 Diabetes: Patient and Caregiver Perspectives.

Diabetic ketoacidosis (DKA) is a life-threatening complication that frequently occurs at diagnosis of type 1 diabetes, occurs more commonly when a patient is misdiagnosed, is the leading cause of death in children with type 1 diabetes, and is associated with worse long-term outcomes. Our retrospective online survey found that 25% of all participants were misdiagnosed and that misdiagnosis was associated with an 18% increased risk for DKA compared to those correctly diagnosed. Adult providers should consider type 1 diabetes when diagnosing type 2 diabetes, and pediatric providers should rule out type 1 diabetes when a patient reports nonspecific viral symptoms.
