Illustrates how to apply new technologies in assessing and monitoring drug adherence. Sheds light on the importance of adherence monitoring in clinical trials. Highlights the role of a multidisciplinary approach involving nurses and pharmacists in supporting adherence. This book provides a critical and comprehensive review of the methodologies available for measuring drug adherence in clinical practice, including those relying on emerging technologies. The authors discuss the risk factors of non-adherence and shed light on how to identify patients at risk of poor adherence. Drug therapies in chronic diseases rely heavily on the patient’s adherence since drugs that are not taken are ineffective and leave the patient at high risk of developing clinical complications. Given the absence of new drugs for the treatment of hypertension, drug adherence is particularly important in these patients to improve blood pressure control.
