Ethics approval and consent to participate
: The study was approved by the Medical Ethics Committee of the University Hospitals Leuven (including the informed/proxy procedure by patients), and written informed consent was obtained by patients before inclusion. Moreover, they were informed about the study, its confidentially and voluntarily nature, and their right to withdraw at any time without consequences for their care. In case of cognitive impairment or diagnosed dementia, the proxy consent procedure was carried out on top of the informed consent procedure. Indeed, as those factors are one of the greatest risk factors for delirium it is important that such patients are included in studies. The bedside nurses received a questionnaire to collect their baseline characteristics and user-friendliness of the ICDSC at the end of the patient enrollment period. The completion and return of those questionnaires was seen as informed consent. The nurses were free to participate, and were informed about the study and the informed consent procedure before the start of the study.
