Core pathogens (if no previous antibiotics):
- Strep.pneumoniae, Haem.influenzae, Staph.aureus (MSSA)
- Sensitive enteric Gram-negative bacilli
Additional pathogens to consider in certain circumstances:
In immunocompromised patients or if there are features suggesting atypical infection. If suspected contact Medical Microbiologist
In immunocompromised patients, those recently on ICU, prior broad-spectrum antibiotic use or structural lung disease
Note: Standard treatment provides adequate cover for aspiration pneumonia
Risk of MRSA if previous stay on ICU, inpatient on ward with endemic MRSA, patients on prior antibiotic therapy (especially quinolones) or patient from Nursing Home.
