Hypertension diagnosis, treatment, and follow-up depend on accurate blood pressure measurement; however, inaccurate measurement techniques are common among healthcare providers. To improve professional performance, continuous education is necessary. Distance education through virtual social network can be used as it is easy to use and accessible.
This study adopted a randomized controlled trial design and was conducted at two hospitals in Mansoura, Egypt. The subjects were selected from two hospitals using Stratified random sampling method in proportion to the total number of nurses. Seventy nurses were included in this study and were randomly divided into the intervention (n = 35) and control (n = 35) groups using block randomization. Data were gathered before and after intervention using a blood pressure measurement knowledge questionnaire and a blood pressure measurement observation checklist. The blood pressure measurement error (the difference between the BP determined by each observer and the reference BP) was calculated for the randomly selected recordings in both groups. The intervention group received 24 blood pressure measurement education sessions using WhatsApp, while the control group received only routine education using traditional lecture.
No statistically significant differences in pretest knowledge scores, performance scores, and range of error were found between both groups, whereas, after intervention, knowledge scores were higher in the intervention group than those in the control group (p < 0.001). The range of error of systolic and diastolic blood pressure values significantly reduced after the intervention in the intervention group, and the posttest performance scores were higher than the pretest performance scores; however, the difference was not statistically significant.
The blood pressure measurement education program via WhatsApp was effective in increasing nurses' knowledge and reducing the range of error; however, a multimodal approach may be required to improve performance scores.

高血压的诊断、治疗及随访依赖于准确的血压测量；然而，医疗服务提供者中测量技术不准确的情况很常见。为提高专业表现，持续教育很有必要。可利用虚拟社交网络进行远程教育，因为其易于使用且可获取。
本研究采用随机对照试验设计，在埃及曼苏拉的两家医院开展。采用分层随机抽样方法，按护士总数比例从两家医院选取研究对象。本研究纳入70名护士，采用区组随机化将其随机分为干预组（n = 35）和对照组（n = 35）。在干预前后，使用血压测量知识问卷和血压测量观察清单收集数据。计算两组随机选取记录的血压测量误差（每位观察者测定的血压与参考血压之间的差值）。干预组通过WhatsApp接受24次血压测量教育课程，而对照组仅接受传统讲座形式的常规教育。
两组在干预前的知识得分、表现得分及误差范围方面均未发现统计学上的显著差异，然而，干预后，干预组的知识得分高于对照组（p < 0.001）。干预组干预后收缩压和舒张压值的误差范围显著减小，且干预后的表现得分高于干预前的表现得分；然而，差异无统计学意义。
通过WhatsApp开展的血压测量教育项目在增加护士知识及缩小误差范围方面有效；然而，可能需要采用多模式方法来提高表现得分。
