Wearable Alert System for Detecting Postoperative Hypotension - Project Summary This Project Aims to Develop a Low-cost, Comfortable, and Easy-to-use Wearable Alert System That Tracks Continuous BP Non-invasively in Patients to Notify Caregivers of Hypotensive Events in the Postoperative Setting. Postoperative Hypotension (poh), When a Patient’s Mean Arterial Pressure (MAP) Falls to Unsafe Levels, Commonly <70 MMHG, Can Occur Frequently in the Time Span Between Leaving the Operating Room and Prior to Discharge From the Hospital. Poh Is a Serious and Common Condition That Has Been Shown to Be Independently Associated With Poor Patient Outcomes Such as Acute Kidney Injury, Stroke, Hospital Re-admission, Myocardial Injury, and DEATH.1–9 During Surgery and Recovery in the Post Anesthesia Care Unit (PACU) or the Intensive Care Unit (icu), a Patient’s Hemodynamics Are Closely Monitored to Support Timely Interventions and Treatment. However, Once the Patient Is Transferred to a Lower Ward for Recovery, Patient Monitoring Is Dramatically Reduced. the Current Method to Monitor a Patient’s BP in the General Ward, Which Relies on Intermittent Spot-checks Performed Manually Every 4-6 Hours by the Nurse Using an Oscillometric BP Cuff, Is Insufficient for Detecting Poh Events. a Recent Study Showed That Almost 50% of Hypotensive Events Went Undetected by Routine Vital Assessments. There Is an Unmet Need for a Technology That Comfortably Monitors a Patient’s BP in the Postoperative Setting. Our Core Technology Is Able to Non-invasively Measure Rapid BP Changes at Any Location With a Palpable Pulse. the Proposed Project Aims Build Upon the Core Technology to Create a Wearable Alert System That Informs Caregivers of Postoperative Hypotensive Episodes. to Do So, a Machine Learning (ML) Classifier for Detection of Hypotensive Episodes Will Be Developed Through Monitoring in the Icu. This ML Classifier Will Undergo Feasibility Testing in the Pacu and Then a Pilot Study in the General Ward. Successful Completion of the Proposed Aims Will Result in a Proof- Of-concept Wearable Alert System That Continuously Monitors BP in the Postoperative Environment in a Low-profile, Wireless, and Comfortable Manner. Such a Technology Has Huge Potential to Change Clinical Practice Through Earlier Detection of Patient Deterioration, Allowing More Timely Intervention and Ultimately Improved Patient Outcomes.
