Severe Community-acquired Pneumonia (sCAP)
Conditions
Brief summary
This study aims to provide high-level evidence for appropriate empirical antibiotic use tailored to the clinical reality in Korea by conducting a randomized controlled trial comparing monotherapy with piperacillin/tazobactam and combination therapy with piperacillin/tazobactam plus a fluoroquinolone in patients with severe community-acquired pneumonia.
Interventions
Piperacillin/tazobactam: 4.5g IV q6h (over 3h)
Piperacillin/tazobactam: 4.5g IV q6h (over 3h) \+ Levofloxacin 750mg IV q24h (over 30min)

Eligibility
Inclusion criteria
* Inclusion Criteria: * Adult patients aged 19 years or older who visited the emergency department and were hospitalized. * Findings consistent with pneumonia diagnosis, meeting all of the following criteria: * Radiologic evidence of pulmonary infiltration on chest X-ray or chest CT. * At least two or more of the following clinical signs: i) Body temperature ≥38°C or \<36°C ii) White blood cell count ≥11,000/µL or \<4,000/µL iii) Presence of purulent sputum or bronchial secretions * Within 24 hours of admission, the patient meets one major criterion or three minor criteria according to ATS/IDSA classification: * Major criteria: i) Invasive mechanical ventilation ii) Use of vasopressors (vasopressor-dependent septic shock) * Minor criteria: i) Respiratory rate ≥30 breaths/min ii) PaO2/FiO2 ≤ 250 iii) Multilobar infiltrates iv) Confusion or disorientation v) BUN ≥20 mg/dL vi) WBC \<4,000/mm³ vii) Platelet count \<100,000/mm³ viii) Hypothermia (temperature \<36°C) ix) Hypotension requiring aggressive fluid resuscitation *
Exclusion criteria
* Transferred from another hospital after \>48 hours of hospitalization * Died within 72 hours of hospital admission * Transferred to another hospital within 14 days of admission * Pneumonia occurring after \>48 hours of mechanical ventilation, including home ventilators * Detection of influenza or SARS-CoV-2 virus within 7 days of hospitalization * Identified non-pneumonia infection requiring antibiotics within 72 hours of admission * Detection of piperacillin/tazobactam-resistant Enterobacterales, Pseudomonas spp., or Acinetobacter spp. in respiratory or blood cultures within the past 90 days * Antibiotic-related adverse events observed within 72 hours of assigned treatment, requiring discontinuation or change of antibiotics
