In 2011 APHCRI was engaged by the Australian Medicare Local Alliance (AML Alliance) to develop a toolkit to evaluate nursing care in general practice. The PESS was developed as a part of this toolkit. The survey was adapted from existing tools and then validated and its reliability established specifically for the Australian practice nurse context.  Version 1 of the PESS as well the PESS example and the How to PESS, documents developed to support its use, are available on the AML Alliance website.
