The world faces grave consequences from the lack of available mental health services and treatment. Mental illness impacts every country, culture and community, with the World Health Organization (WHO) stating that 10% of the global burden of disease is related to mental, neurological and substance use disorders. In low-and middle-income countries, more than 75% of people with mental disorders receive no treatment at all for their disorder. During 2020, as a result of the global pandemic, 93% of countries reported their mental health services were either halted or interrupted (WHO, 2020e). WHO reported a 25% increase in depression and anxiety alone during the pandemic. The Organisation for Economic Co-operation and Development estimates depression and anxiety cost the global economy US $1 trillion dollars a year. All nurses have a health care role in mental health and substance use. ICN strongly advocates for the investment of further education and professional development in this area in order to support individuals and communities achieve the highest attainable standard of health which includes physical, mental and social wellbeing.
