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.

该I-Corps项目的更广泛的影响/商业潜力是开发软件，该软件可以计算传统电话中的心率和可变性统计信息，而无需患者拥有或安装任何软件或硬件。该提出的技术可用于远程评估疾病的严重性，并将患者路由到适当的护理机构。行业专家估计，所有紧急入院中有30％以上是不必要的，并且可以通过更好，更容易访问远程物理监测系统来减少。实时遥测的心率和心率变异性记录可能有助于有效分类并积极地管理患者状况，然后才能升级到紧急情况室。此外，拟议的技术可能是迈出弥合社会经济差距并提高医疗保健权益的一步。该I-Corps项目基于开发无偏差的软件，该软件将使临床医生能够从常规电话中评估和监视患者的当前状态。提出的技术为现有电话增加了一个额外的层，该电话使用语音输入来捕获生命体征，例如心率和心率变异性，并实时与临床共享。该提出的技术旨在允许门诊病人在与临床交谈之前使用该软件来分析生命线，并根据急诊室，紧急护理或家庭治疗进行路由。此外，提出的技术可用于院后事件监测目的，患者每天接听电话以记录生命值并回答一系列问题，以便医生每周审查，作为当前身体状况评估的一部分。该拟议的技术以92％的精度水平有望为临床医生追踪生命力和管理家庭健康状况的简化方法。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和更广泛的影响来审查标准，通过评估来诚实地获得支持。
