SCH: INT: Collaborative Research: Foundations for Caregiver-in-the-loop Suppression of Non-Informative Alarms

用于持续监测医院和家庭环境中的生命体征的系统生成警报，旨在警告护理人员、医院的临床医生或在家的父母需要立即关注的情况。然而，在这些警报中，只有不到1%被认为是可操作的或提供信息的，这导致临床警报疲劳被列为十大健康技术危害之一。虽然在人为因素、业务因素和技术因素方面取得了独立的进展，但它们之间的相互依存关系尚未得到集体考虑。因此，目前用于解决临床告警疲劳的告警抑制系统普遍存在可扩展性差、采用率低和/或在实际应用中性能较差等问题。智能警报2.0将利用护理员在环路中的警报抑制系统，以减少诊所和家庭中非信息性警报的频率。要实现有效的护理者在环报警抑制系统，需要在稳健的报警抑制设计方法和护理员在环路建模和分析方面取得根本进展。建议的设计和分析技术的潜在影响被评估在警报抑制应用、跨儿科病房和对支气管肺发育不良(BPD)患者的家庭监测的医疗场景中。该项目将为设计护理者在回路中的警报系统奠定基础，在该系统中，医生、护士和父母在正确的时间，使用最佳的警报设置来最大限度地提高信息量，监测正确的孩子。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。

Systems used to continuously monitor vital signs in hospitals and home settings generate alarms intended to warn caregivers, clinicians in the hospital, or parents at home of conditions that warrant their immediate attention. However, less than 1% of these alarms are considered actionable or informative, which has led to clinical alarm fatigue being ranged as one of the Top 10 Health Technology Hazards. While there have been advances in human factors, operational factors, and technical factors independently, their interdependencies have yet to be collectively considered. Consequently, current alarm suppression systems aimed at addressing clinical alarm fatigue are generally not extensible, suffer from low adoption rates, and/or have poor performance in practice.This proposal aims to develop foundations for the design of next generation smart alarms. Smart Alarms 2.0 will utilize caregiver-in-the-loop alarm suppression systems to reduce the frequency of non-informative alarms in-clinic and at home. Realizing an effective caregiver-in-the-loop alarm suppression system requires fundamental advances in robust alarm suppression design methodologies and caregiver-in-the-loop modeling and analysis. The potential impact of the proposed design and analysis techniques is evaluated in medical scenarios for alarm suppression applications, spanning pediatric wards and at-home monitoring of Bronchopulmonary dysplasia (BPD) patients. This project will lay the foundations for designing caregiver-in-the-loop alarm systems in which physicians, nurses, and parents monitor the right children, at the right times, using optimal alarm settings to maximize informativeness.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.
