JURAN INSTITUTE CITES OVERUSE OF CATHETERIZATIONS $BlogItemSubject"; $newslink[$countera]="http://www.medjournal.com/blog/archives/2002_06_01_nucmedarchive.php#85191251"; ?>
A report from the Juran Institute, blames that soaring healthcare costs are in part due to poor quality care-- overuse, misues, and waste. They cite cardiac catheterizations as being an example of a procedure overused. Comment: a greater use of cardiac pet would result in fewer unnecessary catheterizations; for that matter, a greater use of SPECT imaging has frequently been shown to decrease unnecessary catheterizations, and decrease overall system costs.

SPECT Myocardial Perfusion Scanning Four Times More Likely to Detect Ischemia in Diabetics $BlogItemSubject"; $newslink[$countera]="http://www.medjournal.com/blog/archives/2002_06_01_nucmedarchive.php#85181666"; ?>
In research presented at the annual Society of Nuclear Medicine meeting, it was shown that SPECT myocardial perfusion scanning was 4 times more likely to detect stress induced myocardial ischemia, compared to ECG stress testing alone. In the 189 diabetics studied, 56% had SPECT perfusion abnormalities, versus 14% with ECG stress abnormalities. Furthermore, abnormalities were more likely to be found in diabetics without angina, as compared to diabetics with angina. Comment: using conservative specificity rates, we know that most of the abnormalities found on SPECT scanning are true findings. This means that in diabetics, ECG stress testing alone misses a large number of patients who have silent ischemia. [ article ] posted at 2:27 PM by Tom Heston, MD
