Wellington Community Bacterial Resistance/Susceptibility to Antibiotics, 2016
Table 2: Non-urinary isolates (% susceptible)
We are pleased to release the antibiotic susceptibility profiles of pathogens most frequently isolated from specimens you have submitted for microbiological investigations at Wellington Southern Community Laboratories (WSCL). The agents reported are those which you would commonly use for treatment.
There are some general comments to make, and then some specific observations that you should take into account when considering the choice of empiric treatments for the common community-acquired infections you see in your clinical practises.
Firstly, the era of complete antibiotic resistance has not yet arrived
! This is fortunate but we are not recommending that you relax your guard when it comes to antibiotic prescribing. On the contrary, we are seeking compliance with antibiotic guidelines and we believe that good antibiotic stewardship now will be rewarded with continuing low resistance rates in the future.
The antibiotic susceptibility tables that follow provide the evidence on which we base treatments and develop “best practice” guidelines.
We outline the salient features of our findings in bullet-point format.

On the basis of “you are what you eat” may we conclude that the Community resistance rates, above, largely reflect what and how much you are prescribing for your patients.
We thank you for your role in keeping these resistance rates down to a very respectable level. We are delighted to work cooperatively with you in the future to maintain this and we look forward to publishing the susceptibility data next year.
Finally – a plea! You will have noted how important it is for us to distinguish clinically significant infection from colonisation. Please help us interpret the significance of our findings by providing clinical details on the laboratory request form… it does make a difference for antibiotic reporting. We will be preparing an antibiogram for the elderly. There is a lot of testing in the frail elderly, and a lot of inappropriate antibiotic prescribing… stay tuned!
