Previous studies have demonstrated that regionalization of resources for cardiac catheterization, percutaneous coronary artery angioplasty (PTCA), and coronary artery bypass graft surgery (CABG) reduces the rate of procedure use.
It was hypothesized that the impact of regionalization would be greater for the elderly and for African-Americans than for other populations.
Discharge medical records of 30,901 patients admitted to a Veterans Affairs (VA) medical center between October 1,1993, and September 30,1994, with a diagnosis of coronary artery disease were analyzed.
The presence of a cardiac catheterization laboratory in the patients'local VA facility significantly increased the likelihood of undergoing catheterization, PTCA, and CABG, as determined by odds ratios and associated confidence limits estimated by logistic regression techniques.
The presence of a cardiac surgical facility also significantly increased the likelihood of having the procedures.
The odds ratios estimating the effects of resource availability were significantly greater for the subgroup of patients aged =70 years than for the younger subgroup for catheterization, PTCA, and CABG and for African-Americans than for white patients for PTCA and CABG.
Thus, within the VA health care system, regionalization of cardiac procedures has a significant impact on utilization rates of tertiary cardiac procedures. (...)
