  1. The Charlson comorbidity index is a tool for predicting the risk of mortality during admission that is attributable to pre-existing comorbid conditions.
  2. CURB-65 is a validated tool for predicting risk of 30 day mortality from CAP. The components are C = confusion (present scores 1, absent scores 0), U = urea (>7 mmol/L scores 1, ≤7 mmol/L scores 0) R = respiratory rate (≥30 scores 1, <30 scores 0) B = Blood-pressure (systolic <90 mmHg or diastolic ≤60 mmHg score 1) and age (≥65 years scores 1, <65 years scores 0).
  3. CRP is serum C-reactive protein level, <5 mg/mL is normal.
  4. PCT is serum procalcitonin level, serum levels >5 ng/mL are strongly associated with bacterial infection and this is the threshold for antibacterial treatment being ‘strongly recommend’43.
  5. BMI is body mass index.
  6. Prior antibiotics records the number of patients who had been taking antibiotics in the community for greater than 24 hours prior to admission.
  7. *Data was incomplete for variables marked with an asterisk: Smoking status N = 74, CRP N = 76, PCT N = 69, BMI N = 67, Influenza N = 54 and Pneumococcal bacteraemia N = 74.
