Medication nonadherence is a widespread problem among cardiovascular patients. Advanced practice providers (APPs) play a critical role in assessing for medication adherence upon hospital admission. A pre–post intervention design was used to determine the effect of an education module on APP knowledge and assessment of medication adherence in cardiovascular patients over a 12-week period in the Division of Cardiology. We found a statistically significant increase in cardiology APP knowledge and assessment of medication adherence upon hospital admission using an education module and providing a valid and reliable assessment tool in the electronic health record.
