ObjectiveTo determine the effect on travel distance for Medicare patients before and after Centers for Medicare & Medicaid Services required that bariatric procedures be performed at Centers of Excellence (COEs).DesignWe calculated the distance traveled to our medical center for the 2 years prior (2004-2005) and 2 years after (2006-2007) COE status was required by Medicare. We also compared the proportion of bariatric cases done in large hospitals with those for esophageal and pancreatic resections, procedures whose effects regionalization would have on patient access have been modeled.SettingUniversity of Texas Southwestern Medical Center, a high-volume tertiary referral center for bariatric surgery.PatientsPatients undergoing bariatric procedures.Main Outcome MeasureTravel distances.ResultsDepending on insurance status, before COEs were required, patients traveled a median of 16 to 25 miles to undergo bariatric operations at University of Texas Southwestern. After COEs were required, the median distance Medicare patients were required to travel increased 76% to 44 miles.ConclusionsCenter of Excellence requirements have increased the travel distance required for Medicare patients. Prior research has shown that outcomes at COEs are no different than those at non-COEs suggesting that the reduced access to care resulting from requiring COE status is not beneficial.
