To identify, evaluate and measure patient adherence to the prescribed treatment, several direct and indirect methods have been developed and used. Direct methods are characterized as the dosage of the active substance/drug metabolite and indirect methods include strategies as questionnaires and interviews, among others. The objective of this review is to identify assessment methods and therapy adherence scales in hypertensive patients.
