Key result
RAND criteria classify 78% of coronary angiographies as appropriate.
Why the study?
The appropriateness of coronary angiography according to RAND (1992) criteria and its relationship to clinical indication and anatomic disease extent were uncertain within the Harvard Community Health Plan.
Observational (n=292)
Yes
A retrospective review found a low rate of inappropriate coronary angiographies (6%) but suggested the RAND criteria lack specificity for predicting actual anatomic disease.
No takes yet. Share an insight, caveat, or question.
Low inappropriate rate (6%) supports selective angiography in HMOs; leaves open whether RAND criteria lack specificity amid rate variation.
Susan Noonan (1995) conducted an observational in Coronary angiography (n=292). Coronary angiography was evaluated on Appropriateness of coronary angiography according to RAND criteria. Among 292 patients undergoing coronary angiography, 78% of procedures were rated appropriate, 16% uncertain, and 6% inappropriate according to RAND criteria.
