Nearly one third of the patients had reading skills less than a 9th-grade level, and 69% had less than 9th-grade skills with numbers. One half of the patients got a score of 70% or less on the test of diabetes numeracy. One problem stated: “You have a prescription for Metformin 500-mg tablets. The label says ‘Take 1 tablet with supper each night for the first week. Then, increase by 1 tablet each week for a total of 4 tablets daily with supper.’ How many tablets should you take with supper each night the second week?” Only 65% selected the correct answer, which is 2 tablets. Patients who were older, were nonwhite, and had less formal education had lower diabetes numeracy test scores.
