Abstract

SUBJECT

This study was to evaluate whether a special lecture on the Chinese Guideline for Blood Pressure Measurement (CGBPM) improves end-digit preference (EDP) of blood pressure (BP) recordings in primary care clinics.

METHODS

In 2012, the doctors working in a clinic received a lecture, which emphasizes that when mercurial sphygmomanometer was used, only 0, and even numbers could be recorded as BP end-digit. In 2016, we collected the BP recordings (2011-2015) of 462 hypertensive patients followed in the educated clinic or in another no-educated clinic. The percentages of 0, 2, 4, 6, 8 in BP end-digit were calculated for evaluating zero EDP, and the percent decline in each year was calculated on the formula: (baseline percentage - actual percentage in a year)/baseline percentage.

RESULTS

In 2011, the percentage of zero end-digit was over 75% for SBP or DBP in both clinics. Against the no-educated clinic, the educated clinic had significant higher percent decline of zero EDP on SBP (31.5% vs -2.6%) and DBP (36.9% vs -14.3%) in 2013, and in 2014 (SBP 38.0% vs 11.6%; DBP 42.8% vs -4.0%). In 2015, the educated clinic still had higher percent decline of zero EDP on DBP (43.3% vs 29.3%). Furthermore, the percentages of zero end-digit for SBP (43.6% vs 49.2%) or for DBP (43.5% vs 59.0%) were lower in the educated clinic in 2015.

CONCLUSION

Education on BP measurement and recording could improve the quality of BP recordings, and this effect may last for three years.

摘要

主题

本研究旨在评估关于中国血压测量指南（CGBPM）的专题讲座是否能改善初级保健诊所血压（BP）记录的尾数偏好（EDP）。

方法

2012 年，在一家诊所工作的医生接受了一次讲座，强调在使用汞柱血压计测量血压时，只能记录 0 和偶数作为 BP 的尾数。2016 年，我们收集了在接受过教育的诊所或另一家未接受过教育的诊所接受治疗的 462 例高血压患者的血压记录（2011-2015 年）。计算 BP 尾数中 0、2、4、6、8 的百分比以评估零 EDP，按以下公式计算每年的百分比下降：（基线百分比-当年实际百分比）/基线百分比。

结果

2011 年，两个诊所的 SBP 或 DBP 的尾数为 0 的百分比均超过 75%。与未接受教育的诊所相比，在 2013 年和 2014 年，接受教育的诊所的 SBP（31.5%比-2.6%）和 DBP（36.9%比-14.3%）的零 EDP 百分比下降幅度明显更高，2015 年 SBP（38.0%比 11.6%）和 DBP（42.8%比-4.0%）的零 EDP 百分比下降幅度也更高。2015 年，教育诊所的 DBP 零 EDP 百分比下降幅度仍更高（43.3%比 29.3%）。此外，2015 年教育诊所的 SBP（43.6%比 49.2%）或 DBP（43.5%比 59.0%）的尾数为 0 的百分比也更低。
