Textually oriented critical discourse analysis and corpus linguistics methods compare 3 executive summaries from the Institute of Medicine reports: the Quality Chasm and Insuring Health series, and the stand-alone report Unequal Treatment. These methods proved effective in studying the social action of language used in those summaries and will be useful in studying a larger corpus of discourse constituting the NHII. Further research will provide information to prevent or mitigate the reproduction of social inequality in healthcare through the proposed NHII. © 2009 Lippincott Williams & Wilkins, Inc.
