Against other measures the Sydney MSIC’s overdose rate is highly disproportionate. Estimates of the number of dependent heroin users in Australia completed for the year 1997, compared with estimates of the number of total non-fatal and fatal overdoses in Australia for 1997/98 yields a rate of 2 overdoses for every 10,000 injections against the MSIC’s rate of 96 overdoses for every 10,000 injections in the 2003 evaluation and rates as high as 146 overdoses per 10,000 injections in the year 2009/10.
