The cost-effectiveness of diabetes interventions plays a crucial role in guiding healthcare policy and resource allocation. Preventive programs, lifestyle interventions, and early screening efforts have proven to be highly cost-effective compared to managing advanced disease complications. Pharmacological innovations, digital monitoring tools, and patient education also demonstrate strong economic value by reducing hospitalization rates and improving quality of life. Economic evaluations help policymakers identify strategies that balance affordability with clinical benefit. Integrating cost-effectiveness analysis into diabetes care planning ensures sustainable health systems, equitable access to treatment, and better long-term outcomes for populations worldwide.
