Decade-Long Trends in Mortality Among Patients With and Without Diabetes Mellitus at a Major Academic Medical Center

The prevalence of diabetes has risen markedly over the past decade and is projected to increase substantially.1 Over 20 percent of hospitalized patients are estimated to have diabetes,2 and individuals with diabetes have historically suffered higher inpatient mortality than individuals without diabetes.3 Over the past decade, evidence from large clinical trials has prompted recommendations for tighter inpatient and outpatient glucose control as well as more stringent blood pressure and lipid management in order to improve outcomes for patients with diabetes.4–6 It is unclear whether the mortality impact of diabetes has changed as a consequence.
