This is the 11th comprehensive annual report describing discharge episodes from subacute inpatient rehabilitation programs provided by Australian facilities that are members of the Australasian Rehabilitation Outcomes Centre (AROC). The inaugural report was published in April 2007 and described the 2005 data; this 11th instalment describes the 2015 data. This report is the first to use the version 4 AN-SNAP classification (to be implemented in Australia in July 2016). For more information about AN-SNAP classification please refer to the AROC website: http://ahsri.uow.edu.au/aroc This report also introduces an extended times series analysis, looking at change in various rehabilitation measures over the most recent five years. The provision of rehabilitation in Australia continues to grow in volume, with 2015 seeing a 6.3% real increase in inpatient episodes of rehabilitation provided. Once again the majority of that volume growth is coming from the reconditioning impairment group.
