Feasibility of Using Resting Heart Rate and Step Counts From Patient-Held Sensors During Clinical Assessment of Medical Emergencies (FUSE): Protocol for Prospective Observational Study in European Hospitals

Feasibility of Using Resting Heart Rate and Step Counts From Patient-Held Sensors During Clinical Assessment of Medical Emergencies (FUSE): Protocol for Prospective Observational Study in European Hospitals

Main study end point To quantify the proportion of patients assessed for an acute complaint who are wearing a device that collects data on vital signs (ie, heart rate and step count). Secondary study end points Secondary end points will focus on four areas of interest: The difference between the heart rate at rest from the wearable device 24 hours, 1 week, and 1 month before assessment by emergency practitioners compared with the first set of vital sign parameters measured on admission to acute care.

Consumer-Grade Neurofeedback With Mindfulness Meditation: Meta-Analysis

Consumer-Grade Neurofeedback With Mindfulness Meditation: Meta-Analysis

Visual representation of consumer-grade device Muse. (A) Muse 2 headband sensors overview. (B) Top-down view of the electrography electrode positions on the subject’s head according to the 10-20 system, standard for electrography recordings. The device includes two forehead electrodes (AF7 and AF8), reference electrodes at FPz, and conductive rubber ear sensors at TP9 and TP10. The FPz electrode serves as a reference point and is positioned at the midline of the forehead.

Enhancing Health Equity and Patient Engagement in Diabetes Care: Technology-Aided Continuous Glucose Monitoring Pilot Implementation Project

Enhancing Health Equity and Patient Engagement in Diabetes Care: Technology-Aided Continuous Glucose Monitoring Pilot Implementation Project

The program ensured CGM device accessibility to all eligible patients. For insured patients, a CGM device was prescribed and dispensed through their pharmacy. The CUHCC used Libre Pro CGM sensors donated by the funder to patients who were uninsured or those with unaffordable copays. We defined the outcome measure of interest as the change in levels of Hb A1c over time. Baseline Hb A1c level is defined as the result closest in time prior to CGM enrollment.

Reliability and Accuracy of the Fitbit Charge 4 Photoplethysmography Heart Rate Sensor in Ecological Conditions: Validation Study

Reliability and Accuracy of the Fitbit Charge 4 Photoplethysmography Heart Rate Sensor in Ecological Conditions: Validation Study

To our knowledge, only a few evaluations of connected device accuracy (eg, accuracy of a smartwatch, as evaluated in this paper) were performed in ecological conditions across different physical activity types. As this type of device is meant to be used in non–laboratory-controlled conditions or free-living conditions, this study aimed to evaluate the accuracy and validity of the PPG HR data from the Fitbit Charge 4 (FC4; Fitbit LLC) across multiple physical activity types.

Usability Testing of a Digitized Interventional Prehabilitation Tool for Health Care Professionals and Patients Before Major Surgeries: Formative and Summative Evaluation

Usability Testing of a Digitized Interventional Prehabilitation Tool for Health Care Professionals and Patients Before Major Surgeries: Formative and Summative Evaluation

The COVID-19 pandemic accelerated the development of digital solutions, which, however, are regulated rigorously by authorities as most app-based solutions require clearance by authorities and certification as a medical device.

Population Digital Health: Continuous Health Monitoring and Profiling at Scale

Population Digital Health: Continuous Health Monitoring and Profiling at Scale

Public-private partnerships (PPPs) present a promising avenue for achieving this as they offer an ethical and effective framework for integrating personal health device data into population health initiatives. These partnerships can be successful, however, only if there are standardized interfaces for integrating data from diverse personal health devices.

Automated Pain Spots Recognition Algorithm Provided by a Web Service–Based Platform: Instrument Validation Study

Automated Pain Spots Recognition Algorithm Provided by a Web Service–Based Platform: Instrument Validation Study

There are different methods for scanning PDs, including using a flatbed scanner, a device that scans flat, thin documents placed on a glass window; a handheld scanner, a portable device that can scan images while being moved over them; a drum scanner, a high-end scanner that uses a rotating cylinder to capture the image; a multifunctional printer scanner, a printer that also includes a scanner function; and a virtual scanner, a software that can use a camera to scan images.

Using Topic Modeling to Understand Patients’ and Caregivers’ Perspectives About Left Ventricular Assist Device: Thematic Analysis

Using Topic Modeling to Understand Patients’ and Caregivers’ Perspectives About Left Ventricular Assist Device: Thematic Analysis

With the limited availability of donor organs, management of end-stage HF has increasingly incorporated the implantation of a left ventricular assist device (LVAD) as a bridge to heart transplantation or as the destination therapy [2]. Web-based health forums have emerged as crucial and highly regarded sources of information for individuals experiencing HF or symptoms [3]. Additionally, these forums serve as valuable platforms for bridging knowledge gaps that may arise between medical consultations.

Data Collection and Management of mHealth, Wearables, and Internet of Things in Digital Behavioral Health Interventions With the Awesome Data Acquisition Method (ADAM): Development of a Novel Informatics Architecture

Data Collection and Management of mHealth, Wearables, and Internet of Things in Digital Behavioral Health Interventions With the Awesome Data Acquisition Method (ADAM): Development of a Novel Informatics Architecture

We designed the ADAM server to have 1-way data communication with wearable device APIs and 2-way data communication between the ADAM-related mobile app and the clinical portal. Figure 1 illustrates the architecture of ADAM (the overall system will be referred to as simply ADAM or the ADAM system, to differentiate from its components), which consists of components for data capture from commercial digital wearables and Io T devices through APIs.
