Mr Wu is a 68yr old man who has recently been discharged home from his local hospital emergency department. He was cleaning out his gutter and fell from his ladder. He was admitted for 28 hours for observation for a lower limb injury. During his hospital stay there was some concern raised regarding Mr Wu's short term memory and he has been referred back to his GP for a follow up regarding assessment for possible dementia. One week after being discharged from the hospital Mr Wu receives a phone call from 'RISE' a dementia research organization. Mr Wu does not recall agreeing to participate in research, and he has no information on the research study from the hospital in his discharge paperwork. The research assistant (RA) on the phone advises that the hospital research team had provided his personal details to RISE. The RA asks Mr Wu if he agrees to participate in a 10 min phone interview regarding his recent hospital experience, he agrees. After 25 mins Mr Wu reports he is feeling tired and a bit muddled and is struggling to recall the details of his admission, his responses indicate that he is becoming a little agitated. The RA is keen for Mr Wu to continue as they are nearly finished, and he continues to ask questions, the interview is finished after 30 mins.

Did the conduct of this research follow accepted legal and ethical principles?
