Self-Reported Morisky Score for Identifying Nonadherence with Cardiovascular Medications

Using the Morisky scale to identify patients who have been nonadherent with chronic cardiovascular medications may be reasonable in some settings; however, the threshold score would have to be chosen based on a trade-off between sensitivity and PPV. These results were likely influenced by the low rate of nonadherence in this cohort. Rewording the questions, increasing the number of questions, and the use of graded response options may improve consistency.
