Home blood pressure (HBP) is useful to decide whether blood pressure (BP) is controlled. However, applying HBP to daily clinical practices is still challenging without easy access to the average HBP. Therefore, we developed a simple method to make a quick decision regarding the controlledness of HBP through high BP counts. We simulated 100 cases of HBP series for each combination of 3 numbers of BP readings (K = 16, 20, 24) and 4 levels of the standard deviations (SDs = 5, 10, 15, 20). A high BP was defined as an individual BP ≥ 135/85 mmHg, and an uncontrolled HBP was defined as a mean HBP ≥ 135/85 mmHg. Validation for the decision method was conducted using actual HBP data. The C-statistics and the accuracy of the high BP counts for the uncontrolled HBP were generally high (> 0.85) for all combinations of Ks and SDs and decreased as SDs increased but remained steady as Ks increased. In validation, the C-statistic of the high BP count-to-total BP reading (C/T) ratio was 0.985, and the C/T ratio ≥ 0.5 showed a sensitivity of 0.957, a specificity of 0.907, and an accuracy of 0.927. The count-based decision method can provide an accurate quick assessment of the controlledness of HBP.
家庭血压（HBP）有助于判断血压（BP）是否得到控制。然而，如果无法方便地获得平均 HBP，那么将 HBP 应用于日常临床实践仍然具有挑战性。因此，我们开发了一种简单的方法，通过高血压计数来快速判断 HBP 的控制情况。我们模拟了 100 例 HBP 系列，每个系列包含 3 个 BP 读数（K=16、20、24）和 4 个标准差（SD）水平的组合（SD=5、10、15、20）。高血压定义为个体 BP≥135/85mmHg，未控制的 HBP 定义为平均 HBP≥135/85mmHg。使用实际 HBP 数据对决策方法进行了验证。对于所有 Ks 和 SDs 的组合，高血压计数对未控制 HBP 的 C 统计量和准确性通常较高（>0.85），随着 SD 的增加而降低，但随着 Ks 的增加而保持稳定。在验证中，高血压计数与总 BP 读数比（C/T）的 C 统计量为 0.985，C/T 比≥0.5 时，灵敏度为 0.957，特异性为 0.907，准确性为 0.927。基于计数的决策方法可以对 HBP 的控制情况进行准确快速的评估。
