Database web app

Electronic data will be extracted from the institutional data lake. The data lake stores all data and events from the EMR information system in a database and can be retrieved using Simple Protocol and RDF Query Language (SPARQL) queries. In the preintervention period, the time stamp of the laboratory results on the EMR will be identified as the time of issuance of the said results. Access to these results by the physicians and nurses will be defined by the time stamp of the first access to the laboratory results’ viewer on the EMR. Access to results on the app will be computed either by the time stamp of the push notification access or to the dedicated page on the app. No other patient-level data such as identifiers or clinical characteristics will be collected. Collected data will be transmitted to the REDCap database web app (REDCap, Vanderbilt University) hosted by the hospital for analysis.

All scenarios were video-recorded by 3 GoPro Hero 5 and 7 Black Edition (GoPro Inc) video cameras mounted on participants and dispatched around them for later analysis. The camera setup was standardized. The investigators double-checked whether the questionnaires were fully and accurately completed. Data was collected using a REDCap database web app (REDCap, Vanderbilt University) hosted at Geneva University Hospitals and interfaced on an iPad Pro iOS 12.4 (Apple Inc). Neither follow up nor retention plans were required.
