Vital Signs Prediction and Early Warning Score Calculation Based on Continuous Monitoring of Hospitalised Patients Using Wearable Technology Hasselt University Ghent University KU Leuven
In this prospective, interventional, international study, we investigate continuous monitoring of hospitalised patients' vital signs using wearable technology as a basis for real-time early warning scores (EWS) estimation and vital signs time-series prediction. The collected continuous monitored vital signs are heart rate, blood pressure, respiration rate, and oxygen saturation of a heterogeneous patient population hospitalised in cardiology, ...
Early warning signals in psychopathology : what do they tell? Ghent University University of Antwerp KU Leuven
Background Despite the increasing understanding of factors that might underlie psychiatric disorders, prospectively detecting shifts from a healthy towards a symptomatic state has remained unattainable. A complex systems perspective on psychopathology implies that such symptom shifts may be foreseen by generic indicators of instability, or early warning signals (EWS). EWS include, for instance, increasing variability, covariance, and ...

An early warning mobile health screening and risk scoring app for preventing in-hospital transmission of COVID-19 by health care workers : development and feasibility study Ghent University
Background: Hospitals have been identified as very high-risk places for COVID-19 transmission between health care workers and patients who do not have COVID-19. Health care workers are the most at-risk population to contract and transmit the infection, especially to already vulnerable patients who do not have COVID-19. In low-income countries, routine testing is not feasible due to the high cost of testing; therefore, presenting the risk of ...
The epidemic volatility index, a novel early warning tool for identifying new waves in an epidemic Institute of Tropical Medicine
Early warning tools are crucial for the timely application of intervention strategies and the mitigation of the adverse health, social and economic effects associated with outbreaks of epidemic potential such as COVID-19. This paper introduces, the Epidemic Volatility Index (EVI), a new, conceptually simple, early warning tool for oncoming epidemic waves. EVI is based on the volatility of newly reported cases per unit of time, ideally per ...
Signaling changes in experience sampling data in real-time: Development and evaluation of statistical process control methods for detecting early warning signals of depression KU Leuven
Detecting early warning signals of impending depressive episodes would pave the way for timely intervention. Since depression is characterized by altered affective experiences, recent studies have investigated whether experience sampling (ESM) data regarding affective experiences in daily life may yield such early warning signals. In ESM studies, participants are instructed to report on their momentary affect at a number of measurement occasions ...
Epitweetr: Early warning of public health threats using Twitter data KU Leuven Hasselt University
BackgroundThe European Centre for Disease Prevention and Control (ECDC) systematically collates information from sources to rapidly detect early public health threats. The lack of a freely available, customisable and automated early warning tool using data from Twitter prompted the ECDC to develop epitweetr, which collects, geolocates and aggregates tweets generating signals and email alerts.AimThis study aims to compare the performance of ...
An intervention including the national early warning score improves patient monitoring practice and reduces mortality University of Antwerp
Aims To investigate the impact of the national early warning score on the frequency and the quality of vital sign registration and to study the association between protocol compliance and patient mortality. Design We conducted a post‐hoc data analysis of a stepped wedge cluster randomised controlled trial in six hospitals. Methods All adult, non‐pregnant patients admitted to 24 wards were included. The intervention comprised an observation ...
