Towards Implementation of Equitable and Effective Non-Communicable Disease Policies Comment on "Barriers and Opportunities for WHO 'Best Buys' Non-Communicable Disease Policy Adoption and Implementation From a Political Economy Perspective: A Complexity Systematic Review".

Non-communicable diseases (NCDs) have been the leading global causes of death and disease burden over the past two decades, but policies and actions to reduce these burdens have been insufficient. Many NCDs are preventable through the implementation of the World Health Organization (WHO) Best Buys - which initially focused on cardiovascular disease, cancer, respiratory disease, and diabetes. Implementing these interventions is complex, requiring transparent and appropriate policy development, policy implementation, and tracking of impact. Barriers to successful implementation are multiple and highly contextual, suchcountry fragility, loci of power, and external pressures. Implementation research is required to identify local barriers and develop strategies to optimize policy implementation to maximize success. Success relies on availability of robust data to permit priority setting, especially where resources are limited, and equitable allocation of healthcare resources to tackle the leading burdens of disease in local contexts. Policy-making must look beyond health to ensure a multisectoral approach to enhancing well-being and sustainability. Global solidarity is required to ensure no countries and no diseases are left behind.
