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

I-Corps项目更广泛的影响/商业潜力是开发一种软件，可以通过传统的电话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。所提出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。业内专家估计，超过30%的紧急入院是不必要的，通过更好、更容易接入的远程生理监测系统可以减少这种情况。使用实时遥测技术记录心率和心率变异性可能有助于有效分诊，并在患者病情升级到急诊室之前主动管理患者病情。此外，拟议的技术可能是缩小社会经济差距和促进医疗公平的一步。I-Corps项目基于一种无设备软件的开发，该软件将允许临床医生通过常规电话评估和监测患者的当前状态。这项拟议中的技术为现有的电话增加了额外的一层，使用语音输入来捕捉心率和心率变异性等生命体征，并实时与临床医生共享。拟议的技术允许门诊病人拨打热线电话，在与临床医生交谈之前，该软件用于分析生命体征，并相应地路由，即急诊室，紧急护理或家庭治疗。此外，拟议的技术可用于院后事件监测目的，患者每天接到电话，记录生命体征，并回答一系列问题，供医生每周审查，作为当前生理状态评估的一部分。该技术准确率高达92%，有望为临床医生提供一种追踪生命体征和管理家庭健康状况的简化方法。该奖项反映了美国国家科学基金会的法定使命，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.
