In New York State, do more percutaneous coronary interventions mean fewer or more complex referrals to cardiac...

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Health Services Research

Background:

• Concerns exist regarding potential financial incentives influencing cardiologists to favor percutaneous coronary intervention (PCI) over coronary artery bypass graft (CABG) surgery.
• This trend is alleged to impact the volume of CABG procedures performed.

Purpose of the Study:

• To investigate the relationship between the increasing rates of PCI and the decreasing rates of CABG.
• To determine if increased PCI performance by cardiologists adequately explains the observed decline in CABG procedures.

Main Methods:

• Analysis of publicly accessible healthcare databases from New York State, California, the US, Canada, and Europe.
• Data collection focused on the years 1997 and 2003.
• Comparison of trends in CABG and PCI procedure volumes and patient demographics across different regions.

Main Results:

• In New York State, CABG procedures decreased by one-third, with no significant change in patient demographics.
• PCI volumes increased substantially, but the proportion of complex 3-vessel PCIs remained constant.
• CABG rates declined in the US (New York and California) but increased in Canada and Europe, while PCI rates rose globally.

Conclusions:

• The observed decrease in CABG procedures in the US is not solely attributable to an increase in PCI performed by cardiologists.
• The trend suggests multifactorial reasons for the decline in CABG rates, beyond potential self-referral for financial gain.
• Further research is needed to understand the complex dynamics influencing surgical and interventional procedure volumes.
