BP assessment BP will be measured by the CHA using the automated device Omron M2® validated. The CHA will be trained to measure BP properly according to the following protocol (Malachias et al, 2016): BP will be measured in both arms; if the readings are different, the arm with the higher reading will be used for subsequent measurements made 1 to 2 minutes apart and the average of these measurements will be considered. A wider cuff will be used for patients with an arm circumference of more than 32 cm.
