Blood donation

A blood donation is a process by which a blood donor is willing to collect blood that will be stored in a blood bank before transfusing a patient during a blood transfusion. Whether in France1, Belgium, Switzerland, Canada, Tunisia, Algeria or Morocco, donating blood is free and voluntary:

The gift

In 2015, the French Blood Establishment collected nearly 3 million donations of blood (donations of whole blood, platelets and plasma) 97.

The need for blood products is constantly increasing. After a long period of declining demand for labile blood products, the situation has reversed since 2001. The need is increasing sharply, at a rate of 1 to 3% per year.

Propaganda of the US Army during the Second World War to encourage blood donation.

The donation of blood is done in several stages:

• the potential donor is greeted by a secretary of the EFS, who gives him a questionnaire to complete: the pre-donation questionnaire;

• He is then received by an EFS doctor for a confidential interview. It is a question of checking one's ability to give one's blood;

• the person gives his blood. The collection, carried out by a nurse, takes about ten minutes for the donation of whole blood, and is longer for the donation of platelets and the donation of plasma (1h30 and 1h);

• the donor is invited to have a snack after the donation. It is essential to be well hydrated and to restore oneself after a donation of blood98.

The factors that can encourage people to donate blood are numerous:

• for pride, for his personal satisfaction

• by solidarity

• indirectly "give" to "receive later if needed"

• the training effect

• by morality: contribution of individuals to the well-being of their fellow men,

Reasons for an increase in needs

Several factors explain this turnaround since 2001:

• the increase in life expectancy leads to an increase in the number of diseases requiring the use of a transfusion therapy. Today, we transfuse more and more at advanced ages of life (⅔ transfused persons are over 60 years old). This trend is likely to increase further in the future given the aging of the population;

• advances in medicine enable the treatment of patients with heavy chemotherapy for leukemia and / or cancer at increasingly advanced ages. These treatments require a large amount of blood products;

• Health professionals have regained confidence in blood products as the risk of transfusions continues to decline (they have been halved in five years). Transfusion is therefore used more systematically to provide people at risk a greater comfort of life

Stabilization of donations

In parallel with this increase in demand, blood samples, like the number of donors, tend to stabilize (around 1.7 million donors in 2009). The supply of health facilities has nevertheless been maintained thanks to rigorous management of the products collected. The expiry rate of products or non-use rose from 1.49% in 2003 to 0.63% at the end of 2006: the management of the manufacturing process is therefore totally mastered and optimized.

Inventories between decrease, stagnation and rise

During the holidays, during outbreaks of gastroenteritis or influenza, there are fewer donors, which leads to a decrease in the number of blood products in the stock, while the needs of patients remain constant. The periods of tension on the stock exist, but the French Blood Establishment has always achieved its mission of ensuring national self-sufficiency of blood products throughout the country.

Accessible goals

To ensure a perfect supply of hospitals and clinics with blood products, it should be permanently 14 days of stock. The red blood cells are kept only 42 days: hence the importance of giving regularly blood. For this, we must conquer new donors and also increase the number of donations per donor.
