Adjustment for atherosclerosis diagnosis distorts the effects of percutaneous coronary intervention and the ranking of hospital performance.
The researchers investigated how adjustment for atherosclerosis affects rankings of hospitals that perform percutaneous coronary intervention (PCI). They found that atherosclerosis is almost always noted in patients with acute myocardial infarction (AMI) who undergo interventional cardiology but less often in medically managed patients, so adjustment for its notation likely removes part of the effect of interventional treatment. Thus, hospitals performing more extensive imaging and more PCIs have higher atherosclerosis diagnosis rates, making their patients appear healthier and artificially reducing the expected mortality rate against which they are benchmarked. The authors concluded that atherosclerosis adjustment is detrimental to hospitals providing more thorough AMI care.
