Definitions

An appropriate diagnostic cardiac catheterization (left heart, right heart, ventriculography, and/or coronary angiography) is one in which the expected incremental information combined with clinical judgment exceeds the negative consequences by a sufficiently wide margin for a specific indication that the procedure is generally considered acceptable care and a reasonable approach for the indication

Appropriate (score 7-9):

test is generally acceptable and is a reasonable approach for the indication

Uncertain (score 4-6):

test may be generally acceptable and may be a reasonable approach for the indication

Inappropriate (score 1-3):
