2017 ACC/AHA/AAPA/ABC/ACPM/AGS/ APhA/ASH/ASPC/NMA/PCNA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines, Pages e127 e248, 2018 with permission from the American College of Cardiology Foundation and the American Heart Association, Inc.2 chapter 1 www.kidney-international.org Some oscillometric devices can be programmed to auto- matically provide a period of rest followed by multiple BP readings with a single activation, a method known as auto- mated of ce BP (AOBP). AOBP can be performed either with the patient alone (i.e., unattended) or with a healthcare provider/technician present (i.e., attended), whereas the other of ce BP methods all require a healthcare provider to be present to perform the measurement. We suggest that AOBP is the preferred method of standardized of ce BP measure- ment (see Practice Point 1.2), but we have no preference for unattended versus attended measurement. Recommendation 1.1: We recommend standardized of ce BP measurement in preference to routine of- ce BP measurement for the management of high BP in adults (1B). This recommendation places a relatively higher value on con- sistency with the BP measurement methods used to de ne BP targets in prior large clinical outcome trials. It also places a higher value on avoidance of misclassi cation to prevent over- treatment or undertreatment of high BP. This recommendation places a lower value on the increased burden to patients, pro- viders, and staff. This recommendation is strong because, in the Work Group s opinion, the importance of of ce BP measured using a standardized versus a routine, non-standardized approach outweighs any potential burden to its implementation.
