I-Corps: Using a digital audio signal to measure heart rate with a smartphone

这个I-Corps项目更广泛的影响/商业潜力是开发软件，从传统的电话呼叫计算心率和变异性统计数据，而不需要患者拥有或安装任何软件或硬件。 拟议的技术可用于远程评估疾病的严重程度，并将患者送往适当的护理机构。 行业专家估计，超过30%的急诊入院是不必要的，可以通过更好、更容易地访问远程生理监测系统来减少。 使用实时遥测技术记录心率和心率变异性可能有助于在将患者病情升级到急诊室之前有效地分类和主动管理患者病情。此外，这项技术可能是缩小社会经济差距和促进医疗平等的一个步骤。这个I-Corps项目是基于一个无设备软件的开发，该软件将允许临床医生通过传统的电话来评估和监测患者的当前状态。这项技术为现有的电话呼叫增加了一个额外的层，使用语音输入来捕获心率和心率变异性等生命体征，并与临床医生实时共享。所提出的技术被设计为允许门诊病人拨打热线，其中该软件用于在与临床医生交谈之前分析生命体征，并相应地进行路由，即，急诊室，紧急护理或家庭治疗。此外，所提出的技术可以用于医院后事件监测目的，其中患者每天接收电话呼叫以记录生命体征并回答一系列问题，以供医生每周审查，作为当前生理状态评估的一部分。该技术的准确率为92%，为临床医生提供了一种跟踪生命体征和管理家庭健康状况的简化方法。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this I-Corps project is the development of software that calculates heart rate and variability statistics from traditional phone calls, without the need for patients to possess or install any software or hardware. The proposed technology may be used to assess the severity of illnesses remotely and route patients to the appropriate care facility. Industry experts estimate that more than 30% of all emergency admissions are unnecessary and could be reduced by better and easier to access remote physiological monitoring systems. A record of heart rate and heart rate variability using real-time telemetry may help to effectively triage and proactively manage patient conditions before they are escalated to emergency rooms. In addition, the proposed technology may be a step towards bridging socioeconomic gaps and advancing healthcare equity.This I-Corps project is based on the development of a deviceless software that will allow clinicians to assess and monitor patients’ current status from conventional phone calls. The proposed technology adds an additional layer to existing phone calls that uses voice input to capture vital signs such as heart rate and heart rate variability, sharing them with a clinician in real-time. The proposed technology is designed to allow an outpatient to call a hotline where the software is used to analyze vitals prior to speaking with a clinician and be routed accordingly, i.e., Emergency Room, Urgent Care, or in-home treatment. In addition, the proposed technology may be used for post-hospital event monitoring purposes where the patient receives a daily phone call to record vitals and answer a series of questions for doctors to review weekly as part of current physiological status assessment. With a 92% accuracy level, the proposed technology promises a streamlined method for clinicians to track vitals and manage health conditions at home.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
