The health insurance company Cigna honored Sierra Vista Regional Medical Center and Twin Cities Community Hospital with Center of Excellence designations for 2012.

Additionally, Sierra Vista received recognition for angioplasty, Caesarean section, disc surgery, hip replacement, knee replacement, orthopedic back surgery and spinal fusion.

Twin Cities Community Hospital was also recognized for Caesarean section, knee replacement and vaginal delivery.

These quality designations are based in part from a hospital’s Centers for Medicare and Medicaid Services Hospital Compare measures, Leapfrog Patient Safety Measures, and mortality and complication rates, according to a recent news release.
