Acute severe community-acquired pneumonia: nosocomial complications and prevention

Also known as Nosocomial infections in CAP patients · Superinfection prevention · ICU-acquired infections in pneumonia

CAP patients admitted to ICU are at high risk for nosocomial (hospital-acquired) superinfections during their stay. Common: VAP (ventilator-associated pneumonia — 1, develops 48h after intubation), CRBSI (catheter-related bloodstream infection), C. difficile colitis, UTI (catheter-associated), surgical site infection (if surgery performed). Risk factors: prolonged ventilation, broad-spectrum antibiotics, immunosuppression, severity of illness. Prevention: VAP bundle (head elevation, daily SAT+SBT, oral chlorhexidine, subglottic suction, cuff pressure), CRBSI bundle (full barrier precautions, chlorhexidine skin prep, daily review of line necessity), antibiotic stewardship (minimise duration, de-escalate), early mobilisation, hand hygiene.

Meet the patient

A 68-year-old man is intubated on day 1 for pneumococcal CAP, started on ceftriaxone and azithromycin, then broadened to piperacillin-tazobactam on day 4 for persistent sepsis. On day 5 he spikes 38.9 degrees Celsius, throws thick purulent secretions, and the chest X-ray shows a new right lower-lobe infiltrate his admission film did not have.^[1]

This is not his pneumonia getting worse — it is a second, different infection acquired under your ventilator, and the organisms will be healthcare-associated and multidrug-resistant. Hold that thought and every prevention measure below becomes obvious.^[1]
