The study, which appears in the October 27 issue of JAMA, investigates the outcomes of over 600,000 Medicare enrollees who underwent a cardiac procedure called a percutaneous coronary intervention (PCI) at a US acute care facility between 1999 and 2001. It concluded that patients who underwent PCI at a hospital without a cardiac surgeon onsite had a 29% overall increased risk of mortality compared to those who had the procedure in a hospital with surgical backup.
PCI is a non-surgical procedure that unblocks narrowed coronary arteries, often using a balloon to open a constricted artery and a wire stent to keep the artery clear. Although it is a non-surgical procedure, complications that require emergency cardiac surgery, may arise.
In the United States, hospitals with catheterization laboratories but without cardiac surgery on location are rapidly developing PCI programs in hopes of improving patient care and remaining competitive. "Our findings suggest that the current 'wave' to move PCIs into hospitals that don't have coronary artery bypass surgery programs should be questioned," said lead author Dr. David Wennberg, adjunct associate professor of community and family medicine and of medicine at DMS.
Headed by Dr. David Malenka, associate professor of medicine and a cardiologist at Dartmouth-Hitchcock Medical Center, the study used data from a total of 178 hospitals that performed PCIs without onsite cardiac surgery and 943 hospitals that performed PCIs with onsite cardiac surgery.
