Wireless Assessment of Respiratory and Circulatory Distress - Europe

Hospital patient monitoring in Europe is often intermittent, which can delay detection of clinical deterioration during hospitalization and after discharge. The WARD-EU study aims to describe current monitoring practices and to evaluate the feasibility, acceptability, and usability of the WARD-CSS (Wireless Assessment of Respiratory and Circulatory Distress - Clinical Support System), an algorithm-based continuous monitoring system. The study seeks to assess whether WARD-CSS can be integrated into routine hospital and post-discharge care to support earlier detection of patient deterioration and improved patient monitoring.

Evaluation of a Single-lead ECG Patch-based Telemetry System for In-hospital Monitoring

"This investigator-initiated, prospective, single-center clinical study evaluates the performance and clinical utility of a single-lead electrocardiogram (ECG) patch-based telemetry system for hospitalized patients who require in-hospital telemetry ECG monitoring. The system integrates real-time centralized surveillance (MEMO-Cue) with post-hoc analytic review (MEMO-Care) using ECG signals recorded by the MEMO Patch M, aiming to enable timely recognition of clinically important arrhythmias and to inform treatment decisions under routine inpatient conditions. Adults (≥19 years) indicated for continuous ECG monitoring during admission are enrolled after written informed consent, with a planned sample size of 100 to yield approximately 90 evaluable participants (10% anticipated dropout). The design does not include randomization or blinding. Study procedures include a screening visit (eligibility and baseline data), an inpatient monitoring period of at least 12 hours and up to 8 days with simultaneous MEMO-Cue monitoring and MEMO Patch M recording, and an end-of-visit assessment when MEMO-Care analytic results become available. Concomitant therapies deemed clinically necessary are permitted and documented, and adverse events are prospectively assessed. Clinical utility endpoints quantify care impact and timeliness: (1) rate of treatment plan changes (e.g., initiation or modification of anticoagulants or antiarrhythmic drugs, cardioversion scheduling, device implantation, or other actions); (2) time to recognition (days) of major arrhythmias-atrial fibrillation (AF), ventricular tachycardia (VT), pause, ventricular premature complex (VPC), and supraventricular tachycardia (SVT)-based on MEMO-Cue alarms or MEMO-Care results with objective confirmation; (3) reduction ratio in recognition time when identified earlier by MEMO-Cue versus MEMO-Care; and (4) proportion of participants with shortened recognition time by MEMO-Cue. Clinical performance endpoints assess detection characteristics and agreement between MEMO-Cue alarms and MEMO-Care findings: (1) clinical sensitivity (true positive / \[true positive + false negative\]); (2) precision, i.e., positive predictive value (true positive / \[true positive + false positive\]); and (3) positive concordance rate (proportion of MEMO-Care-detected arrhythmias alerted by MEMO-Cue). Safety is captured as treatment-emergent adverse events after device application, including device-related skin reactions, detachment, or signal dropouts, with severity graded per NCI-CTCAE v5.0 and relationship to device recorded. By characterizing real-time patch-based telemetry alongside analytic review and its influence on diagnostic timing and management, the study aims to generate practical evidence supporting feasibility, reliability, and workflow compatibility of single-lead patch telemetry for in-hospital ECG monitoring.

Home Monitoring Study for Surgical Patients

This clinical trial is designed to evaluate the accuracy, usability, and patient compliance of the Wellvii VitalDetect, an FDA-cleared (510(k) K231625), Class II medical device intended for non-invasive monitoring of vital signs including blood pressure, pulse rate, and temperature. The study will focus on comparing measurements obtained in a home environment using the device to those collected in a clinical setting, with the goal of validating the device's performance for real-world, at-home use. The Wellvii VitalDetect is a portable, battery-operated, spot-check monitor that uses finger-based technology for most parameters and an infrared sensor for forehead-based, non-contact temperature readings. It is designed for use by adults (18 years or older) in a home environment and is not intended for continuous monitoring. In addition to the cleared vital signs, the device displays other wellness parameter for general health tracking. A smartphone application supports the user experience by delivering usage instructions and data display. The study will assess: * Measurement accuracy compared to standard clinical instruments * Patient ease-of-use and engagement with the device * Adherence to regular self-monitoring schedules * Overall user satisfaction and confidence I home-based monitoring This research will contribute to the growing body of evidence supporting remote patient monitoring solutions and aims to advance the adoption of decentralized technology-enabled healthcare delivery. The study aligns with Wellvii Inc.'s mission to transform healthcare delivery by enabling continuous, connected health monitoring from the home. The ultimate goal is to empower patients and healthcare providers with real-time, clinically actionable health at a that can lead to earlier intervention, improved outcomes, and reduced system burden.

Personalized Health Coaching for Patients With HF

Frailty in heart failure (HF) patients contributes to poor outcomes, emphasizing the need for effective management. In many previous studies, frailty interventions have mainly targeted physical frailty or focused community-dwelling patients, neglecting the multidimensional needs of hospitalized individuals. As a frailty for HF patients need to include clinical, functional, cognitive, and social domains, nurses must assess it holistically and provide personalized support, especially during care transitions. This study aims to evaluate the effectiveness of a nurse-led, personalized health coaching program for hospitalized HF patients with frailty through a randomized controlled trial. This 12-week intervention program targets hospitalized HF patients with frailty. After screening frailty HF patients using validated tools such as Fried's phenotype (FP), Tilburg Frailty Indicator (TFI), participants will be randomly assigned to either an intervention or control group. The intervention group will receive personalized health services, including pre-discharge education and weekly telephone coaching, addressing clinical, functional, psycho-cognitive, and social frailty domains. Psychiatric support and community integration program will be provided as needed. The control group will receive standard care. Frailty, QoL, and clinical outcomes will be measured at baseline, 12 weeks, and 24 weeks. The primary outcomes will be improvements in frailty and QoL. Frailty will be measured both multidimensional and each of the four domains of frailty for HF patients. This study will clarify the role of multidimensional personalized interventions in addressing adverse outcomes related to frailty in patients with HF, thereby providing evidence of their necessity in its management.

On-Demand Oxygen Delivery System Study

The main goal of this study is to determine if supplemental oxygen given only when the patient is inspiring (demand delivery) is more effective than constant-flow oxygen given during all phases of the breath regardless if the patient is breathing it in. A previous study in volunteers (NCT02886312) showed that the oxygen saturation in the blood and the concentration of oxygen breathed out from the lungs (end-tidal oxygen) was higher when given in demand (inhalation only) mode. A secondary goal is to determine in patients, whether turning oxygen delivery off during expiration improves the accuracy of end-tidal CO2 (Carbon Dioxide) monitoring. This was found to be the case in the previous volunteer study. The investigators want to determine if these improvements are also observable in relatively healthy patients undergoing procedural sedation and analgesia. The efficacy of the demand mode will be determined by measuring the resulting difference in oxygen saturation and end-tidal oxygen levels. The investigators will alternate between traditional oxygen delivery (continuous flow) and demand delivery (flow only during inhalation) for two minutes in each mode after which oxygen saturation and end-tidal oxygen will be measured. End-tidal CO2 measurement will be compared with those during the brief time when O2 flow is stopped.
