All ethical considerations are outlined in the Participant Information and Consent Form that will be distributed to participants. All patients admitted to ARDU who fulfil the inclusion criteria will be approached about participating in the study. All participants will require signing an informed consent to participate. All information and data obtained during the study will be kept in strict confidence. Upon recruitment, every participant will be assigned an anonymous code and the lists linking the code with personal identifying information will be kept secure and separate from the data. Only the Principal Investigator and researchers authorized by the PI will have access to the identifying lists. Every participant will undergo the same procedures with slightly variable order. No deception will be used and participants will be informed as to exactly what the study is about. All participants will be informed at the time of providing consent to participate that they can withdraw from the study at any time and that this will not affect the care they will receive.
