Abstract

OBJECTIVE:

To examine whether hyperglycemia at the time of presentation was associated with outcomes in patients admitted to non-intensive care settings with community-acquired pneumonia (CAP).

RESEARCH DESIGN AND METHODS:

Prospective cohort study of consecutive patients admitted to six hospitals between 15 November 2000 and 14 November 2002.

RESULTS:

Of the 2,471 patients in this study (median age 75 years), 279 (11%) had serum glucose at presentation >11 mmol/l: 178 of the 401 patients (44%) with a prior diagnosis of diabetes and 101 of the 2,070 patients (5%) without a history of diabetes. Of patients hospitalized with CAP, 9% died and 23% suffered an in-hospital complication. Compared with those with values < or =11 mmol/l, patients with an admission glucose >11 mmol/l had an increased risk of death (13 vs. 9%, P = 0.03) and in-hospital complications (29 vs. 22%, P = 0.01). Compared with those patients with admission glucose < or =6.1 mmol/l, the mortality risk was 73% higher (95% CI 12-168%) and the in-hospital complication risk was 52% higher (12-108%) in patients with admission glucose >11 mmol/l. Even after adjustment for factors in the Pneumonia Severity Index, hyperglycemia on admission remained significantly associated with subsequent adverse outcomes: for each 1-mmol/l increase, risk of in-hospital complications increased 3% (0.2-6%).

CONCLUSIONS:

Hyperglycemia on admission is independently associated with adverse outcomes in patients with CAP, with the increased risks evident at lower glucose levels than previously reported.
