I was referred to the Endoscopy Dept a while ago and spent several days waiting for a phone call giving me an appointment date and time. In the end I went back to the hospital and tracked down the nurse who booked the appointments. I then saw Ms Demetriou who has recommended an endoscopy and a colonoscopy on the same day (I will be sedated). I was told that someone would call me later that day with an appointment date. Two weeks went by with no phone call so I decided to visit the department again. The nurse was helpful and showed me the appointment book (nothing is automated). There were several pages of names without dates yet allocated. Mine was several pages back. It appears that the more simple procedures are booked fairly quickly, and the lengthy ones have a waiting time of three to four months. So I don't expect to receive a phone call until early next year.
