[Pneumonia in an internal medicine service]

Area of Science:

• Internal Medicine
• Pulmonology
• Epidemiology

Context:

• Pneumonia is a frequent cause of admission and a complication in internal medicine wards.
• A retrospective analysis of 107 pneumonia patients admitted to a University Hospital in Lisbon during 1990 was conducted.
• The study population comprised patients with a mean age of 70.7 years, with a significant prevalence of comorbidities.

Purpose:

• To analyze the clinical characteristics, treatment, and outcomes of pneumonia patients in an internal medicine setting.
• To identify prognostic factors influencing pneumonia outcomes.
• To inform strategies for infection prevention and optimize therapeutic approaches for lower respiratory tract infections.

Summary:

• Bronchopneumonia was the most common radiographic pattern (52.3%).
• Common comorbidities included chronic obstructive airways disease (20.5%), cardiovascular illness (54.2%), and hypertension (15.8%).
• Leukocytosis (67.3%) and hyperglycemia (62.6%) were frequent laboratory findings. Ampicillin was the most used antibiotic (46.7%).
• The overall mortality rate was 29%, with advanced age and pre-existing conditions being significant prognostic factors.

Impact:

• Highlights the significant burden of pneumonia in internal medicine, emphasizing its high mortality rate.
• Underscores the importance of age and comorbidities as key predictors of patient outcomes.
• Provides insights for improving lower respiratory tract infection prevention and guiding appropriate antimicrobial therapy selection.
