U.S. veterans are dying because of delays in diagnosis and treatment at VA hospitals. At least 19 veterans have died because of delays in simple medical screenings like colonoscopies or endoscopies, at various VA hospitals or clinics, CNN has learned. The new document obtained by CNN shows a worse problem than has previously been made public by the VA. As CNN has previously reported, as many as 7,000 veterans were on a backlog list -- waiting too long for colonscopies or endoscopies -- at VA facilities in Columbia, South Carolina and Augusta, Georgia.
