Sometimes people want these direct concrete answers. NHS hospitals have very little in the way of staff that can take the time to answer questions. Doubtful that the secretary would know the answers or would have a nurse or doc nearby to answer them.
The best time to ask questions would be at pre-assessment. They should have the answers.
Staff do not always want to give concrete answers because things can change in a heartbeat with no warning, and they have no control over that. Then people complain.
I think that many complaints come from people because they have unrealistic expectations from the service.
Once (as a staff nurse) I was sent to staff an 18 bed day surgery ward all by myself and I have no experience of surgery. I work in medicine. They had taken so many recent medical admissions that they had no beds for the minor surgery patients that were booked to come in. So they opened a closed unit, put 18 beds in there, and sent me to staff it. I had 18 people come in at the same time. There is a lot to do to get them ready for theatre and seconds count. The wife of one of the men called to ask a million questions about the operation. Remember I was alone down there and I had minutes to get people who were first on the list ready.
Staying on the phone with her for as long as she wanted would have meant that I didn't get many of the patients organised and ready in time and they may have missed their ops. I was as nice as I could be on the phone considering the rush and the stress I was in the middle of at that time. But I had to be quick with her.
Then she put in a formal complaint because "She rang the ward to find out information and the nurse would only spend 5 minutes on the phone". That 5 minutes that I was generous enough to give nearly caused another patient to miss his window. This is how rushed and fast we are moving. The complaints department let it go because they knew that she had unrealistic expectations of me at that time and they know that THEY are not going to staff these units decently anytime soon.
Considering that there was a bed crisis at the time and that they nearly had to cancel all the minor surgical cases to get the acute medical patients in, it was a miracle that everyone got in a bed and got their day operations that day. It took a lot of hard work and many 12 hour shifts without breaks on the part of the staff to make that happen. Her husband got his op and was safe. It was a miracle that he even got in considering what was going on for that day. But all the unreasonable bitch could think about was the fact that I, as a nurse overwhelmed trying to single handedly run a ward (where every second counts and there are no second chances, could not give her more than 5 minutes. And I really couldn't.
If I had been fucking around on the phone answering relatives questions it would have been enough to totally screw up the surgical list and cause people to miss their ops, no doubt.
