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.

这个i-Corps项目的更广泛的影响/商业潜力是开发根据传统电话计算心率和变异性统计数据的软件，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设施。业内专家估计，超过30%的紧急入院是不必要的，如果更好、更容易地访问远程生理监测系统，可能会减少这一比例。使用实时遥测记录心率和心率变异性可能有助于在患者病情升级到急诊室之前有效地分诊和主动管理。此外，这项拟议的技术可能是朝着弥合社会经济差距和促进医疗公平迈出的一步。这个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传统电话评估和监控患者的当前状态。这项拟议的技术在现有电话呼叫的基础上增加了一层，使用语音输入来捕获心率和心率变异性等生命体征，并与临床医生实时分享。这项拟议的技术旨在允许门诊患者在与临床医生交谈之前拨打热线，在热线上使用软件分析生命体征，并相应地进行转接，即急诊室、紧急护理或家庭治疗。此外，拟议的技术可用于医院后事件监测目的，即患者每天接到记录生命体征的电话，并回答一系列问题，作为当前生理状态评估的一部分，供医生每周审查。凭借92%的准确率水平，这项拟议的技术承诺为临床医生提供一种简化的方法来跟踪生命体征和管理家中的健康状况。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
