[Respiratory infections in Emergencies].

Area of Science:

• Infectious Diseases
• Pulmonology
• Microbiology

Context:

• Respiratory infections constitute a significant portion of overall infections.
• Lower respiratory tract infections, including pneumonia, are a major concern.
• Acute bronchitis, chronic obstructive pulmonary disease (COPD) exacerbations, and pneumonia are key conditions.

Purpose:

• To outline the management strategies for common respiratory infections.
• To emphasize the importance of antibiotic stewardship in treating bacterial respiratory infections.
• To highlight the role of severity assessment and risk stratification in guiding treatment decisions.

Summary:

• Acute bronchitis in immunocompetent patients is typically viral and managed symptomatically.
• COPD exacerbations are often triggered by infection, necessitating empirical antibiotic choice based on clinical factors and Pseudomonas aeruginosa risk.
• Community-acquired pneumonia (CAP) management involves prognostic scales (PSI, CURB-65) for treatment decisions and etiological diagnosis.
• Healthcare-associated pneumonia (HCAP) and nosocomial pneumonia (NP) carry higher risks of multidrug-resistant microorganisms (MMR), requiring tailored empirical treatment.

Impact:

• Informed clinical decision-making for respiratory infection management.
• Improved patient outcomes through appropriate antibiotic use and risk-based treatment strategies.
• Reduced morbidity and mortality associated with severe respiratory infections, particularly those caused by multidrug-resistant pathogens.
