Treatment monitoring of hypertensive patients can be achieved using data from blood pressure measurements obtained in follow-up visits, from sporadic 24 hours ambulatory blood pressure monitoring (ABPM) and from patients' self-measurements. Blood pressure self-measurement values seem to be the easiest to obtain. A disadvantage is the uncertainty about the accuracy with which patients report these values. In this randomised clinical trial with 48 hypertensive outpatients we compared reported self-measurements with the stored values in the devices. One group was unaware of the storing capacity of the device. All patients measured their blood pressure twice in the morning and twice in the evening over a period of 14 days. Endpoints of our analysis were the comparison of the number of measurements performed and the missing and manipulated values between the two groups. The non-informed group measured blood-pressure more frequently than the informed group (76.1 vs. 58.8 measurements; p = 0.0005). Compared to the informed group, the number of agreements between stored and reported values was smaller in the non-informed group (95.7% vs. 87.5%; p = 0.026) whereas reporting of fictional data only occurred in the non-informed group (0 vs. 55; p = 0.002). Our data show, that use of blood-pressure devices with a memory function increases the accuracy of reported self-measured values and can lead to better treatment monitoring.
高血压患者的治疗监测可以通过随访中获得的血压测量数据、偶尔进行的24小时动态血压监测（ABPM）以及患者的自我测量来实现。血压自我测量值似乎是最容易获得的。一个缺点是患者报告这些值的准确性存在不确定性。在这项针对48名高血压门诊患者的随机临床试验中，我们将报告的自我测量值与设备中存储的值进行了比较。一组患者不知道设备的存储功能。所有患者在14天内每天早晚各测量两次血压。我们分析的终点是比较两组患者进行的测量次数以及缺失和被篡改的值。不知情组测量血压的频率高于知情组（76.1次对58.8次测量；p = 0.0005）。与知情组相比，不知情组中存储值与报告值之间的一致数量较少（95.7%对87.5%；p = 0.026），而虚构数据的报告仅发生在不知情组（0对55；p = 0.002）。我们的数据表明，使用具有记忆功能的血压设备可提高报告的自我测量值的准确性，并有助于更好地进行治疗监测。
