TYLER — The Cystic Fibrosis Clinic at The University of Texas Health Science Center at Tyler is one of only four centers in the United States to be awarded the 2011-2012 Quality Care Award from the Cystic Fibrosis Foundation. “We learned a lot from this process of quality improvement. Achieving the Quality Care Award is very humbling. “It is a recognition of our commitment to providing excellent care to people with cystic fibrosis in Northeast Texas,” said Varsha Taskar, M.D., the clinic’s associate director and a pulmonologist. Cystic fibrosis (CF) is a chronic disease that affects the lungs and digestive system of about 30,000 children and adults in the United States.
