Donor organ shortage actual figures. Promoting organ donation based on trust is an unavoidable health policy to be able to provide organs to patients who are awaiting transplant. Around 120,000 people only in the United States today are awaiting a kidney, liver, heart or lung transplant. However, the mismatch between organ supply and demand continues to grow negatively. Although 95% of Americans believe that organ donation should be supported, only 50% have signed up to be a donor, so promoting policies to encourage donation seems unavoidable, according to The Lancet (see “Organ donation depends in trust” HERE).
