As non-communicable diseases escalate globally, timely and accurate monitoring of health indicators like blood pressure and blood glucose becomes critical. The Scanbo device, a Bluetooth-enabled point-of-care tool, promises to revolutionise this monitoring by offering quick and reliable measurements.
To validate the concordance of the results of the Scanbo device compared with the Omron for blood pressure and with the diagnostic lab method for blood sugar.
This observational cross-sectional pilot study was conducted in the urban slum of Vijinapura (Bengaluru) to evaluate the accuracy of the Scanbo device. We enrolled 128 participants for blood pressure assessments and 69 for blood glucose measurement, selecting adults from the community based on predefined criteria. The primary variables measured included systolic and diastolic blood pressures and blood glucose levels, with data collected using both the Scanbo device and standard measurement methods for comparison. Data were recorded and analysed to ensure consistency and reliability. Statistical analyses were performed using Jamovi 2.3.28 solid version (The Jamovi project, 2021, https://www.jamovi.org), employing Bland-Altman plots to assess agreement, Cohen's kappa for inter-rater reliability, and ROC curves to determine diagnostic accuracy. Sensitivity, specificity, positive predictive value and negative predictive value were also estimated.
The Scanbo device showed excellent accuracy in measuring systolic blood pressure (AUC = 0.985) and blood glucose (AUC = 0.973), with substantial agreement in reliability (Cohen's kappa > 0.67 for all measurements). Diastolic blood pressure measurements were also accurate (AUC = 0.924), although slightly less so than systolic measurements. The mean differences between the Scanbo and standard measurements, sensitivity, specificity, positive predictive value and negative predictive value were within clinically acceptable limits.
The Scanbo device demonstrates a high level of accuracy and reliability comparable to standard methods for systolic and diastolic blood pressure and blood glucose measurements. These findings support the potential integration of the Scanbo device into routine clinical practice, particularly for community health settings and patient self-monitoring.
随着全球非传染性疾病的增加，及时准确地监测血压和血糖等健康指标变得至关重要。Scanbo设备是一种支持蓝牙的即时护理工具，有望通过提供快速可靠的测量结果来彻底改变这种监测方式。
验证Scanbo设备与欧姆龙血压计测量血压结果以及与诊断实验室血糖测量方法结果的一致性。
在维贾纳普拉（班加罗尔）的城市贫民窟进行了这项观察性横断面试点研究，以评估Scanbo设备的准确性。我们招募了128名参与者进行血压评估，69名参与者进行血糖测量，根据预先定义的标准从社区中选择成年人。测量的主要变量包括收缩压、舒张压和血糖水平，使用Scanbo设备和标准测量方法收集数据进行比较。记录并分析数据以确保一致性和可靠性。使用Jamovi 2.3.28稳定版（Jamovi项目，2021年，https://www.jamovi.org）进行统计分析，采用布兰德-奥特曼图评估一致性，科恩kappa系数评估评分者间信度，ROC曲线确定诊断准确性。还估计了敏感性、特异性、阳性预测值和阴性预测值。
Scanbo设备在测量收缩压（AUC = 0.985）和血糖（AUC = 0.973）方面显示出极佳的准确性，在可靠性方面有高度一致性（所有测量的科恩kappa系数> 0.67）。舒张压测量也很准确（AUC = 0.924），尽管略低于收缩压测量。Scanbo设备与标准测量之间的平均差异、敏感性、特异性、阳性预测值和阴性预测值均在临床可接受范围内。
Scanbo设备在收缩压和舒张压以及血糖测量方面表现出与标准方法相当的高水平准确性和可靠性。这些发现支持将Scanbo设备整合到常规临床实践中的可能性，特别是在社区卫生环境和患者自我监测方面。
