Hyperglycemia at Admission Is Associated with Excess Mortality Among Pneumonia Patients

Hyperglycemia at admission has been associated with adverse outcomes among hospitalized patients with community-acquired pneumonia (CAP) — including patients without preexisting diabetes (Diabetes Care 2005; 28:810, and J Infect 2010; 60:99). In this multicenter, prospective study, investigators examined whether hyperglycemia at hospital admission predicts death in CAP patients with and without preexisting diabetes.

Nearly 7000 patients (mean age, 60) were evaluated; 5% died within 28 days, 8% within 90 days, and 9% within 180 days. Mortality at 28, 90, and 180 days was significantly higher among patients with diabetes than among those without diabetes. Among patients without preexisting diabetes, those with admission glucose levels >108 mg/…
