 Study Visit 3 SV3 will occur during the week before the participant is discharged from hospital. Discharges from hospital are planned in advance and therefore it is anticipated that this visit is likely to be 3-5 days prior to the actual discharge from hospital. The same tests will be repeated at this visit. However, if discharge occurs within 1 week of SV2 then the tests will not be repeated and the scores obtained at SV2 will be used in any calculations.
