The appropriateness of coronary angiography and coronary artery bypass surgery in the Trent regional health authority was assessed by comparison with predetermined consensus criteria. Forty-nine percent of coronary angiographies were considered to be entirely appropriate in relation to the patient's clinical condition, but 21 percent were deemed inappropriate. Coronary artery bypass surgery was considered appropriate in 55 percent of patients, but inappropriate in 16 percent. Audit by "appropriateness" scores may help to determine which patients should first be investigated and treated when resources are limited and waiting lists are long.
