Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study endpoints are the performance of the deterioration detection and uneventful recovery algorithms. Algorithm performance will be assessed using receiver operating characteristics (ROC) analysis expressed as the area under the curve (AUC) with corresponding 95% confidence intervals. Sensitivity, specificity, positive and negative predictive value will be calculated accordingly. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoints are:Sensitivity, specificity and the time interval between algorithm-based detection and clinical confirmation by medical staff for complications such as atrial fibrillation, tamponade and acute coronary syndrome are calculated.Accuracy and data coverage of video-derived heart rate and respiratory rate measurements under varying lighting conditions, patient movement, skin type and occlusion will be determined by comparing it to reference standards obtaining using the IntelliVue MX40 and data availability.Accuracy and feasibility of extracting additional physiological and behavioral parameters including oxygen saturation, eye movement, paleness and patient movement from the generated video data.Proportion of data loss and incorrect detection of the two ROIs (head and chest).Performance of the data management solution expressed as the RMSE as a function of bitrate (kb/s) for several compression models & storage solutions.Acceptability of the video-based monitoring among healthcare providers, patients and family in terms of privacy, comfort, feeling of safety, ease of use and trust in the system, will be assessed using questionnaires, focus groups and interviews. | — |
