对于自我测量血压是有用的，病人报告的测试结果必须是可靠和准确的。到目前为止，没有研究直接测量患者报告的自我测量血压值的准确性和可靠性。30名高血压患者（69 +/- 11岁）被要求在家中使用高精度Omron TC监测仪测量血压14天，并在患者日志中记录所有读数。为了评估记录的可靠性，未告知患者器械的记忆容量。我们将自动存储的血压读数与相应的日志条目进行比较，以分析删除（低报）、添加（高报）和报告检测结果的精确度。普遍的模式是低报，平均为36% +/- 24%（3%至89%），明显高于高报（9% +/- 11%; 0%至38%）。报告精密度（相应时间的相同值）为76% +/- 34%（0%-100%）。这种观察员误差不影响自动存储值和日志条目的组比较，尽管估计的一致性范围很宽。血压控制，高血压的持续时间，年龄，或以前使用的自我测量和模式的日志entries没有被发现是预测患者的reliability.Our结果表明，一个重大的观察员误差报告的自我测量血压值。这种偏差可以通过配备存储器的血压设备来减少。(C)1998年美国高血压杂志有限公司
For self-measurement of blood pressure to be useful, patient reporting of test results must be reliable and accurate. Until now no study directly measured the accuracy and reliability of patients' reporting of self-measured blood pressure values.Thirty hypertensive patients (69 +/- 11 years) were instructed to measure blood pressure at home over 14 days with the highly accurate Omron TC monitor and to keep a record of all readings in a patient logbook. To assess the reliability of the records, patients were not informed about the memory capacity of the device. We compared automatically stored blood pressure readings with the respective logbook entries to analyze deletion (under-reporting), addition (over-reporting), and precision of reporting of test results.The prevalent pattern was under-reporting, averaging 36% +/- 24% (3% to 89%), which occurred significantly more than over-reporting (9% +/- 11%; 0% to 38%). The precision of reporting (identical values at corresponding times) was 76% +/- 34% (0% to 100%). This observer error did not affect group comparisons of automatically stored values and logbook entries, although the estimated limits of agreement were wide. Blood pressure control, duration of hypertension, age, or previous use of self-measurement and patterns of logbook entries were not found to be predictive of the patients' reliability.Our results demonstrate a substantial observer error in the reporting of self-measured blood pressure values. This bias may be reduced by memory-equipped blood pressure devices. (C) 1998 American Journal of Hypertension, Ltd.
