The RAND/UCLA Appropriateness Method criteria for carotid endarterectomy were confirmed by subsequent trials for 44 indications, covering almost 30% of operations, and refuted for none.
Does the RAND/UCLA Appropriateness Method accurately predict the appropriateness of carotid endarterectomy as determined by subsequent RCTs?
The RAND/UCLA Appropriateness Method Criteria for carotid endarterectomy demonstrated high predictive validity when compared to subsequent randomized clinical trials.
We assessed the predictive validity of an expert panel's ratings of the appropriateness of carotid endarterectomy by comparing ratings to the results of subsequent randomized clinical trials. We found the trials confirmed the ratings for 44 indications (covering almost 30% of operations performed in 1981) and refuted the ratings for none.
Shekelle et al. (1998) studied this question. The RAND/UCLA Appropriateness Method criteria for carotid endarterectomy were confirmed by subsequent trials for 44 indications, covering almost 30% of operations, and refuted for none.
