This paper highlights some key actions social workers can take to help improve the physical health of people living with mental illness. Despite an 80% comorbidity rate , many people living with mental illness still do not receive a physical health check-up. For this and other reasons, people living with mental illness die, on average, 10-20 years prematurely. This early death is usually preceded by years or decades of poor health. Using a collective impact approach, this paper discusses actions to increase autonomy, advocate for better access to quality physical health care, and minimise iatrogenic harm for people living with mental illness.
