This project directly links to the 5th National Mental Health and Suicide Prevention Plan priority of improving the physical health of people living with mental illness (Priority 5) and the recommendations of the Productivity Commission Inquiry Report into Mental Health on improving the physical health of people living with mental illness. The project aims to update and repeat the analysis of enhance and extend findings from the earlier ‘Mortality of people using mental health services and prescription medications’ (ABS, 2017) to update and extend its findings. This 2017 data integration project investigated the use of mental health-related treatments amongst the Australian population in 2011 as well as mortality outcomes for people accessing mental health related treatments compared with the rest of the population. This research uses existing records that are de-identified and confidentialised appropriately by the ABS within the context of the other security features of the DataLab. Statistical analysis using the ABS MADIP datasets are conducted within the ABS’s DataLab environment. A better understanding of the linkage between mental health related services and medications use will enable policy makers, service providers and health advocacy bodies to monitor progress in reducing the life expectancy gap, target service initiatives for the key elevated risks of premature mortality, illness preventive and early intervention policy development.
