*3.1. Economic Benefits*

Although well-developed countries spend a large amount of their gross domestic products on healthcare systems, the expenditures spent may not help to boost health outcomes. Furthermore, the increases in medical care expenses and health benefits indicate that additional strategies should be incorporated to enhance the efficiency of healthcare systems and protect public investments [49]. Despite having the highest healthcare expenditures, the U.S. has reported that it has not increased its life expectancy or last-day quality of life [50]. There is a rapid increment in relative economic demands, due to the sharp elevation in the age of the population and increasing chronic diseases. It has been estimated that the senior population will increase from 14 million to 19 million in 2020 and, by 2050, it will increase to 40 million. The impact of these demands has been observed in European regions. By employing BD as a tool for forecasting models, the economy of the healthcare sector can be improved, in order to develop expenditure projections for potential medicinal hazards, discover various policies that can assist in resolving intricate circumstances, and implement the most efficient approaches against various threats. It has been reported that BD might produce more than 300 billion in savings per year for the U.S. healthcare sector [50].
