Video monitoring FOR early Signaling of adverse EvEnts: the validity of camera based detection of irregular heart rate

Forty percent of unanticipated deaths and deteriorations in hospitals occur in low- acuity departments. This alarming figure reflects the limited degree to which the cardiorespiratory status of patients is monitored in these departments, due to the obtrusiveness and expense of existing monitoring technologies, as well as the unpractically high clinical workload and cost that deployment of such technologies would entail. The FORSEE-project explores video monitoring of the cardiorespiratory status of the patient as an innovative unobtrusive method that could eventually aid to reduce workload for staff and better predict deterioration of adverse events. The main objective of this study is to determine the validity of camera based monitoring to detect irregular heart rate in comparison with ECG. Secondary objectives are the validity of the camera based monitoring technology to detect respiratory rate, oxygen saturation and different activity levels. Another secondary objective is to evaluate user and patient experience. This is an observational study, subjects will be asked to add the contactless camera set-up to the standard procedure. The main endpoint is the correspondence between the camera based heart rate and other vital signs in comparison with the standard contact sensors. All data will be analysed retrospectively and the data collected will be used for algorithm development.

Irregular heart rate can be detected with a camera-based monitoring technology.

Endpoint correspondence between the camera based heart rate and other vital signs in comparison with the standard contact sensors: T0 Camera-based vital signs and reference signals will be collected at least 10 minutes before, during and at least 10 minutes after the cardioversion. This data will be analyzed retrospectively, no clinical decisions will be based on this study data. Endpoint patient experience: T0 Questionnaires will be handed out after the cardioversion and patients will be asked to complete the questionnaire during their hospital stay. T1: When all 48 patients have participated in the trial, a selection of patients will be asked to participate in a focus group (within 3 months after data collection). Endpoint user experience: T0: All involved healthcare providers will be asked to complete a questionnaire about their experience with the video monitoring technology after the cardioversion. T1: When all 48 patients have participated in the trial, a selection of healthcare providers will be asked to participate in a focus group.
