Comparison of Public Health Investments of Various Countries Amid a Need for Greater Transparency: A Narrative Review.

Abstract

A robust health system demands investments in public health and healthcare as they aid in closing the health protection gap. They are primarily responsible for longer life expectancies, disease prevention, and protection. Loopholes in the public health system were formed due to a lack of transparency and have only worsened throughout COVID-19. Spending more on public health is associated with fewer deaths, fewer food-borne illnesses, better sanitation, food safety, clean air and water, increased immunizations to stave against infectious diseases, and a decline in low birth weight. A comprehensive literature and data search was conducted using web-based search engines like PubMed, National Center for Biotechnology Information (NCBI), Google Scholar, Science Direct, and the New England Journal of Medicine. The review study standpoints healthcare spending, out-of-pocket expenditures, and other monetary use in various low-to-high-income countries, and the results are graphically represented. Countries with a strong public health system provide all the necessary aid to protect their citizens. They have cost-effective, readily available resources with fewer out-of-pocket expenditures (OOPs), government schemes, and health insurance to help their people. During our research, it was found how little the Indian government spends on healthcare as a percentage of gross domestic product (GDP) as compared to 'thought-to-be' poor countries like Bhutan.
