Public cost and access to primary care for hyperglycemic emergencies, Clark County, Nevada.

Diabetes mellitus accounts for 5.8% of the total health care costs of citizens of the United States. Hospitalization expenses produce 40.5% of these costs. We sought to determine the public expenditure and major precipitators of admissions for uninsured diabetic hyperglycemic emergencies at a large public hospital. Of 247 diabetic emergency admissions over a 30 month period 49% (n = 121) of these patients had no medical insurance. The uninsured patients were younger and had relatively mild disease in comparison to the insured patients. These patients identified a primary physician in only 6% of the cases and had a higher incidence of admissions associated with lack of medications. We conclude that public funds to provide access to primary care and enhancement of employer-sponsored health insurance programs may decrease the numbers and costs of hospitalizations due to hyperglycemic emergencies in uninsured patients with diabetes mellitus.
