Non-communicable diseases (NCDs) represent a growing share of global health expenditure, yet comparable data across countries remain scarce. Understanding how costs vary by disease phase, sex, and age group is critical for anticipating future health system needs and evaluating the fiscal implications of prevention and treatment policies.
In their 2025 study published in Population Health Metrics, Samantha Grimshaw, Emily Bourke, and Tony Blakely present the first comprehensive dataset estimating NCD expenditure across all 38 OECD countries. Using Australian and New Zealand expenditure data, combined with Global Burden of Disease estimates, the authors calculate per capita spending by disease, phase, and demographic group. Their analysis reveals marked variations in NCD-related expenditure and provides a valuable foundation for forecasting future health costs, assessing system efficiency, and guiding evidence-based investments in NCD prevention and care.
