KHA-CARI has been developing guidelines de novo for an Australian New Zealand target audience since 1999. KDIGO was set up in 2002 to explore the possibility of developing international chronic kidney disease (CKD) guidelines. The science and evidence based care of those with CKD are universal and independent of geographical location/ national borders. It is important to avoid duplication of effort by organizations and to efficiently use the available expertise and resources. As a consequence KHA-CARI have committed to adapting selected KDIGO guidelines to meet Australian and New Zealand circumstances and requirements rather than producing separate guidelines. This summary guideline is an adaptation of the KDIGO Clinical Practice Guideline for Acute Kidney Injury.1 The summary includes a brief description of the adaptation methodology and the adapted recommendations and suggestions for each subtopic. The complete KHA-CARI adapted guideline can be accessed at the KHA-CARI website (http:// www.cari.org.au). The ultimate purpose of the adapted guideline is to provide a comprehensive listing of recommendations relevant to Australian and New Zealand practice following a detailed review and update of the KDIGO guidelines.
