Although recent studies have demonstrated geographic variation in pharmaceutical use and spending,1- 4 regional variation in medication adherence in Medicare has not been explored.5 Medication adherence is a critical quality measure and is especially important for Medicare beneficiaries with heart failure (HF), a common condition in which medications can save lives and reduce downstream costs.6 We used 2007-2009 national Part D data for a 5% random sample of Medicare beneficiaries to study regional variation in HF medication adherence.
