The RANZCP report The economic cost of serious mental illness and comorbidities in Australia and New Zealand looks specifically at those with a serious (or severe) mental illness. It provides useful insight into a highly vulnerable group who on average die decades younger than the general population, often due to preventable or treatable physical health problems.
The report calculates the economic cost of premature death of people with mental illnesses including schizophrenia, bipolar disorder, psychoses and severe anxiety and depression to be $15 billion (.9% of GDP) annually, and the cost overall to be $56.7 billion (3.5% of GDP).
The RANZCP report provides further evidence of the need for coordinated care packages for people with severe and complex needs. Poor physical health compromises mental health recovery, and has a substantial cost impact on the national economy.
