Comments:
•
The time frame when the infection was acquired can play a role in the patient’s recovery following the surgical
procedure.
•
Infection was reported in 28.4% (1,046/3,679) cases audited since the data collection commenced for infections.
The infection rate between emergency and elective admissions varies between 18.1% and 40.0% respectively.
•
Pneumonia and septicaemia comprised 73.9% (773/1,046) of the cases where infection was identified of these
cases 47.1% (364/773) were acquired postoperatively
•
The infection rate across specialties varied, reflecting the casemix of individual specialties.
•
The infective organisms identified were:
Clostridium difficile, Candida albicans, Escherichia coli, Enterobacter
aerogenes, Enterococcus, Klebsiella, Lactobacillus,
Methicillin-resistant
Staphylococcus aureus,
Methicillin-
sensitive
Staphylococcus aureus, Staphylococcus haemolyticus, Staphylococcus pyogenes, Staphylococcus
aureus, Varicella
, yeast and mixed organisms.
•
Strategies for implementing surgical site infections surveillance have been implemented overseas
(19)
and in
Australia.
(20)
•
A standardised surgical site infections surveillance method was implemented in Victoria in 2002. Since
implementation, a research study found a need to facilitate the refinement of recommended surgical antibiotic
prophylaxis regimens and expand surveillance strategies on a national level.
