Several Countries Have Inadequate Blood Supply

The World Health Organization (WHO) suggests that to have adequate supplies every 1,000 people in a country, 10 to 20 blood donations are needed .Blood transfusion not only save lives but also improves health. Ensuring an adequate blood supply should be an essential part of the health care policy of every country.  By research it is found that 119 out of 195 countries don’t have enough blood that they can meet the needs of the country. Access care in the low income countries have been increasing thereafter increasing the demand for blood transfusions which will grow the gap between demand for blood and global supply. Research is focused on estimating the gap between demand for blood and global supply based on every countries medical need. They also focus on the blood safety and risk of infection transmission.

To compare each country’s requirements ,they estimated the need for 20 medical conditions based on United States  data and calculated the popularity of the condition in a country and then calculated the amount blood that would be necessary for providing a transfusion to a patient in need. The global blood supply was around 272 million units and the global demand in 2017 was 303 million units – a shortage of 30 million units, hence around 119 countries to summed up to 100 million units. Lower income countries relatively had low demands as compared to high-income countries but these countries comparatively had great estimated shortfall in supply which affected the supply of the different blood cells. To meet the demands in 2017, 40 countries would require 30 donations per 1000 people .One limitation of the researchers study was that their estimates were based on ideal blood transfusion which may not reflect elsewhere specially in countries where the neglected diseases like malaria, pregnancy and childbirth complications are severe even though substantial difference in the quality and safety of blood still exist.
