Abstract：
To practice standardized office blood pressure (OBP) measurement guidelines pragmatically, we developed an intelligent assisted OBP (IOBP) measurement system in the Chinese community, which can automatically obtain two or three BP values after a 5-min rest before the patients visit the doctor and transfer values to the community medical network in real time. We conducted a comparative study to investigate the agreement among IOBP, awake ambulatory BP (ABP), and conventional auscultatory OBP at different BP levels. Participants were divided into three groups according to BP, with 120/80 mmHg and 160/100 mmHg as the cut-off points. Attended IOBP, unattended IOBP, and auscultatory OBP were randomly measured before ABP monitoring. In total, 245 participants were included in the analysis. The mean systolic attended/unattended IOBP, auscultatory OBP, and awake ABP were 135.0, 136.7, 135.6, and 136.2 mmHg, respectively. Bland-Altman analysis revealed a bias of -1.1 and 0.5 mmHg for systolic attended/unattended IOBP compared with awake ABP in the overall sample. For auscultatory OBP, the bias was -0.4 (attended) and 1.2 mmHg (unattended). The discrepancy between the systolic attended/unattended IOBP and awake ABP was inconsistent at different BP levels. In Group 1 the values were -8.4 and -6.9 mmHg, whereas in Group 3, the values were 9.4 and 10.0 mmHg. BP measured using the IOBP measurement system was in accordance with awake ABP and conventional OBP, and can be a good choice in the Chinese community.
摘要：
务实地实践标准化办公室血压（OBP）测量指南，我们在中国社区开发了智能辅助OBP（IOBP）测量系统，可以在患者就诊前休息5分钟后自动获取两到三个BP值，并将值实时传输到社区医疗网络。我们进行了一项比较研究，以调查IOBP之间的协议，清醒动态血压（ABP），和不同BP水平的常规听诊OBP。参与者根据血压分为三组，以120/80mmHg和160/100mmHg为分界点。参加IOBP，无人值守的IOBP，ABP监测前随机测量听诊OBP。总的来说,245名参与者被纳入分析。平均收缩期监护/未监护IOBP，听诊OBP,清醒的ABP分别为135.0、136.7、135.6和136.2mmHg，分别。Bland-Altman分析显示，在整个样本中，与清醒的ABP相比，收缩期监护/无人监护IOBP的偏差为-1.1和0.5mmHg。对于听诊OBP，偏倚分别为-0.4(出席)和1.2mmHg(无人出席).在不同的BP水平下，收缩期监护/未监护IOBP与清醒ABP之间的差异不一致。在第1组中，值分别为-8.4和-6.9mmHg，而在第3组中,该值分别为9.4和10.0mmHg.使用IOBP测量系统测量的BP符合清醒ABP和常规OBP，在华人社区是一个不错的选择。
