Research has shown that certain high-risk surgeries and treatments are more likely to result in successful outcomes when they performed by experienced doctors at hospitals with large numbers of these procedures. The Leapfrog Group, a hospital quality ranking organization, sets standards on safe volumes for a number of procedures, including certain cardiovascular procedures.

The most recently reported volume data for Lahey Clinic are from June 2010. The table below shows how Lahey's volume compares to the Leapfrog Group's recommended standards.
