Expansion of Abbreviations and Acronyms for Patients

This is a prospective, two-arm, parallel, individually randomized controlled trial to estimate the effect of expansion on patient comprehension (primary outcome) of abbreviations and acronyms in their health records. English-speaking adult patients with diagnosed heart failure who receive primary care at three urban hospitals in New York City will be considered. The investigators hypothesize that expansion will significantly increase patient comprehension of abbreviations and acronyms in the health record.
