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 项目更广泛的影响/商业潜力是开发一种软​​件，可以通过传统电话计算心率和变异性统计数据，而无需患者拥有或安装任何软件或硬件。行业专家估计，超过 30% 的紧急入院是不必要的，并且可以通过更好、更容易访问的远程生理监测系统来减少。使用实时遥测的心率变异性可能有助于在患者被送往急诊室之前对其进行有效分类和主动管理。此外，所提出的技术可能是缩小经济差距和促进医疗保健公平的一步。该 I-Corps 项目基于无设备软件的开发。该技术将允许通过传统电话来评估和监控患者的当前状态，该技术在现有电话的基础上增加了一个额外的层，该层使用语音输入来捕获心率和心率变异性等生命体征，并与临床医生共享这些信息。所提出的技术是实时设计的。允许门诊病人拨打热线电话，在与临床医生交谈之前使用该软件分析生命体征并进行相应的路由，即急诊室、紧急护理或家庭治疗。此外，可以使用所提出的技术。用于出院后事件监测，患者每天都会接到电话，记录生命体征并回答一系列问题，供医生每周检查，作为当前生理状态评估的一部分，该技术的准确率预计为 92%。外星人的方法该奖项反映了 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。
