In Thailand, the UHC scheme has made significant strides in ensuring healthcare availability, capacity, funding, and management. However, a notable weakness, from my experience, lies in the imbalance between primary prevention and tertiary care. The Department of Disease Control (DDC) allocates a disproportionately low budget—about 10-20%—to primary prevention compared to what is spent on tertiary prevention, such as hospital treatments. This trend is not unique to Thailand but is observed globally, where the emphasis often shifts to the cost of health only after falling ill, despite primary prevention being more cost-effective. Addressing this imbalance is crucial for a more sustainable and effective healthcare system.
