Certificate of Need for Cardiac Care: Controversy Over the Contributions of CON
Certificate of Need; CABG; PCI; panel data methods
Objective: To test whether state Certificate of Need (CON) regulations influence procedural mortality or the provision of coronary artery bypass graft surgery (CABG) and percutaneous coronary interventions (PCI). Data Sources: Medicare inpatient claims obtained for 1989-2002 for patients age 65+ who received CABG or PCI. Study Design: We used differences-in-differences regression analysis to compare states that dropped CON during the sample period, versus states that kept the regulations. We examined procedural mortality, the number of hospitals in the state performing CABG or PCI, mean hospital volume, and statewide procedure volume for CABG and PCI. Principal Findings: States that dropped CON experienced lower CABG mortality rates relative to states that kept CON, although the differential is not permanent. No such mortality difference is found for PCI. Dropping CON is associated with more providers statewide and lower mean hospital volume for both CABG and PCI. However, statewide procedure counts remain the same. Conclusions: We find no evidence that CON regulations are associated with higher quality CABG or PCI. The regulations may limit the number of facilities performing these procedures, and the potential cost savings from this restriction should be investigated.
