2025 Multiprofessional Critical Care Review: Adult Online-Community-Acquired and Hospital-Acquired Pneumonia

Video Transcription

Video Summary

This lecture covers pneumonia types: community-acquired (CAP), hospital-acquired (HAP), and ventilator-associated (VAP). Pneumonia is a leading cause of death globally, with CAP often caused by Streptococcus pneumoniae and atypical bacteria; viral pathogens are also common. Risk factors include alcohol use, immunosuppression, and elderly age. Early recognition and treatment, including coverage for MRSA and pseudomonas in severe cases, are critical. Macrolides are added for atypical coverage and have anti-inflammatory benefits. Corticosteroids reduce mortality and complications in severe CAP cases with septic shock or respiratory failure, typically administered for 5–7 days. For HAP and VAP, empiric broad-spectrum antibiotics guided by local resistance patterns are essential, with shorter treatment courses (5–7 days) recommended except in immunocompromised or resistant infections. Prevention strategies focus on minimizing intubation duration, oral care, and subglottic secretion drainage. Biomarkers like procalcitonin may guide de-escalation but not initial therapy in severe cases.
