STRATIFICATION GUIDE 2018 The ACHS, in collaboration with relevant medical colleges, associations and specialty societies have developed the following stratification variables to enable like organisations to be grouped for the purpose of comparison. Four levels of comparison are available: An individual organisation s data results compared to ALL organisations who submit data for a particular indicator. An individual organisation s data results compared to all other organisations submitting data within the same sector, that is, public or private. Within the Australasian Clinical Indicator Report (published annually), data are compared by state, public/private and on a metropolitan/non-metropolitan basis. These historical data are accessible from the Retrospective ACIR data in full tab via the following link on the ACHS website: http://www.achs.org.au/publicationsresources/australasian-clinicalindicator-report/ An individual organisation s data results compared to other organisations classified according to defined stratification variables as described in the section below. The criteria used to stratify an indicator set are based on the factors that the Working Party believes may impact how different healthcare organisations perform.
