DKA occurs predominantly in patients with type 1 (insulin-dependent) diabetes mellitus, but 10% to 30% of cases occur in newly diagnosed type 2 (non–insulin-dependent) diabetes mellitus, especially in African Americans and Hispanics.1,2 Between 1993 and 2003, the yearly rate of U.S. ED visits for DKA was 64 per 10,000 with a trend toward an increased rate of visits among the African American population compared with the Caucasian population.3 Europe has a comparable incidence. A better understanding of the pathophysiology of DKA and an aggressive, uniform approach to its diagnosis and management have reduced mortality to <5% of reported episodes in experienced centers.4 However, mortality is higher in the elderly due to underlying renal disease or coexisting infection and in the presence of coma or hypotension.
