We are developing algorithms that will de-identify free-text nursing notes as well as clincians doing the same task. A database of nursing notes manually de-identifed by hired clinicians is being created that will be made publicly available for the testing and evaluation of de-identification algorithms. We are also gathering statistics about the performance of human de-identifiers. We will use those statistics to test whether our de-identification algorithms perform at least as well as human
