  1. *Charlson Index of comorbidity [7].
  2. **LRTI, lower respiratory infection; SSTI, skin and soft tissue infection; UTI, urinary tract infection; Other infections include intra-abdominal infections, bone/joint infections, and bacteraemia with undefined source.
  3. ***Resistant Gram negative bacteria were resistant to cefuroxime, co-amoxiclav or ciprofloxacin. Two patients had both MRSA and resistant Gram negative bacteria.
