Abstract

Because there are no definitive guidelines for performing right heart catheterizations or controlled clinical trials demonstrating medical benefit, the value and necessity of performing routine right heart catheterizations for coronary artery disease have been questioned. This Texas Medical Foundation Health Care Quality Improvement Program project was designed to ensure medical necessity and proper documentation of right heart catheterization when performed as part of a bilateral procedure. Medicare claims data were used to identify Texas facilities where rates of bilateral catheterizations suggested that right heart catheterizations were being performed routinely. Five facilities were found to have rates of bilateral procedures exceeding 70%. Suggested guidelines for performing right heart catheterizations were prepared by the Texas Medical Association Committee on Cardiovascular Diseases. These guidelines, together with the facility's data on its rate of right heart catheterizations, were presented by the Texas Medical Foundation to the staff of each facility. They were asked to examine their individual facility's procedures for ensuring medical necessity and to develop and implement process improvement plans. Medicare claims data were analyzed to determine the rates of bilateral catheterizations before and after the plans were instituted. The statewide rate of bilateral procedures decreased from 27.2% to 21.3% (p < 0.005). Rate reductions for 4 facilities implementing improvement plans were statistically significant (p < 0.001): at the 1st facility, the rate decreased from 74.3% to 25.0%; at the 2nd, from 85.0% to 21.0%; at the 3rd, from 76.7% to 17.7%; and at the 4th facility, from 85.4% to 42.9%. The rate for the facility not implementing an improvement plan increased from 86.4% to 89.1%. Reductions in rates of bilateral procedures at the 4 facilities suggest that many procedures previously performed were routine and not medically indicated. Presentation of data and practice guidelines to facilities may have contributed to their ability to improve processes.
