Whether it's in traffic, at a restaurant or in line for UNC basketball tickets, no one likes to wait.
But for thousands of Americans who need organ transplants, waiting is more than an annoyance -- it's the difference between life and death.
"There is a gap between the number of people on the wait list and those who receive an organ, and it's only getting larger," said Brandi Mueller, a nurse in the lung transplant department at UNC Hospitals.
According to the U.S. Department of Health and Human Services' organ donation Web site, about 63 people across the nation receive an organ transplant each day. Another 16 people on the waiting list die each day because not enough organs are available.
Kidneys are the organ most in demand, with 53,000 people on the waiting list as of Oct. 11. Patients are also waiting for liver, pancreas, intestine, heart and lung transplants, and cornea and skin transplants are common as well.
Patients who need organs are registered by their local transplant centers with the United Network for Organ Sharing, which maintains a national waiting list and matches donors to recipients.
UNOS assigns each patient a priority status based on medical criteria, which will eventually dictate when the patient receives an organ.
When an organ becomes available, a local transplant coordinator uses the UNOS computer to find a successful match. The coordinator must then contact a transplant surgeon to arrange organ transport and, finally, surgery.
The patient is expected to cover operations cost, and although it varies by transplant, the process is expensive.
