Management of Lower Respiratory Tract Infections

Initial Assessment and Triage Decision

The European Respiratory Society recommends that immediate hospital referral is required if any of the following are present: temperature <35°C or ≥40°C, heart rate ≥125 beats/min, respiratory rate ≥30 breaths/min, blood pressure <90/60 mmHg, cyanosis, confusion, or drowsiness, or suspected pleural effusion or cavitation 3
The European Respiratory Society suggests that additional factors mandating hospital consideration include age >65 years with comorbidities, institutionalized patients, recent hospitalization within previous year, or inability to manage at home due to vomiting, social exclusion, dependency, or altered mental status 1, 3

The European Respiratory Society recommends that antibiotics are only prescribed when bacterial infection is suspected based on clinical features suggesting pneumonia or purulent exacerbation of chronic bronchitis, with a treatment duration of 5-7 days 1, 2
The European Respiratory Society suggests that amoxicillin or tetracycline should be the first-line antibiotic choice for community-acquired LRTIs managed at home 1, 2

The European Respiratory Society recommends that the majority of patients with exacerbations benefit from antibiotic treatment, and that sputum culture should be obtained before starting antibiotics, particularly if hospitalization is required 4, 5

The European Respiratory Society strongly recommends annual influenza vaccination for high-risk patients, such as those aged ≥65, with chronic cardiac or pulmonary disease, diabetes, or institutionalized 4, 5
The European Respiratory Society recommends pneumococcal vaccination for at-risk adults 4, 5
