Hyperglycemia as a predictor for mortality in veterans with pneumonia

Area of Science:

• Geriatric Medicine
• Infectious Diseases
• Endocrinology

Background:

• Elderly individuals often present with multiple comorbidities, including diabetes mellitus and pneumonia.
• Pneumonia is a common and serious infection in the elderly population.
• Hyperglycemia is a frequent complication in hospitalized patients, particularly those with infections.

Purpose of the Study:

• To investigate the impact of hyperglycemia on length of stay (LOS) and mortality in elderly veterans hospitalized with pneumonia.
• To determine if hyperglycemia is an independent risk factor for adverse outcomes in this patient group.

Main Methods:

• Retrospective evaluation of elderly veterans (age > 60) admitted for pneumonia at two VAMC's (Lexington, KY and Iron Mountain, MI).
• Patients were categorized into two groups: hyperglycemia and normoglycemia.
• Statistical analysis, including the 2-sample independent t-test, was used to compare LOS and mortality rates between groups.

Main Results:

• Patients with hyperglycemia had significantly longer mean LOS compared to those with normoglycemia at both Lexington (39.5 vs 16.5 days, p < .01) and Iron Mountain (21.5 vs 13.6 days, p < .01).
• Mortality rates were significantly higher in patients with hyperglycemia at both sites (Lexington: 33% vs 13%, p < .05; Iron Mountain: 30% vs 13%, p < .05).
• Age was not found to be a significant predictor of LOS or mortality.

Conclusions:

• Hyperglycemia is a significant predictor of prolonged hospitalization and increased mortality in elderly veterans with pneumonia.
• Effective management of blood glucose levels may be crucial for improving outcomes in this vulnerable population.
• Further research is warranted to explore specific interventions for hyperglycemia in geriatric pneumonia patients.
