Variation in health care-associated infection surveillance practices in Australia.

In the absence of a national health care-associated infection surveillance program in Australia, differences between existing state-based programs were explored using an online survey. Only 51% of respondents who undertake surveillance have been trained, fewer than half perform surgical site infection surveillance prospectively, and only 41% indicated they risk adjust surgical site infection data. Widespread variation of surveillance methods highlights future challenges when considering the development and implementation of a national program in Australia.
