Charts were available on 824 subjects, some of whom had been identified in the administrative database with > 1 diagnosis. Thus a total of 1136 diagnoses were available for verification against clinical records. Of the 824 subjects, 680 (83%) had their administrative database diagnoses confirmed on chart review. The majority of subjects who were \u201cfalse-positive\u201d for a given rheumatic disease on administrative data had a true diagnosis of a similar rheumatic disease.
