Evaluate the accuracy of an algorithm at identifying ethnic minorities from administrative claims for enrollment into a clinical trial.
Claims data from a health benefits company.
We compared results of a three‐step algorithm to self‐reported race/ethnicity.
Data Sources/Study Setting
Using the algorithm, we identified subjects with high probability of being minority and ascertained self‐reported race/ethnicity.
We identified 164 subjects as likely minority based on our algorithm. Of these, 94 completed the survey and 87 identified themselves as black or ispanic. The positive predictive value of the algorithm was 93 percent (CI: 85–97).
Claims data can be used to efficiently identify minorities for participation in clinical trials.
