"Good experience but one concern"

I attended the combined assessment unit as my doctor had referred me there due to being acutely anaemic, the thought I needed a blood transfusion.

I went there with my son and daughter in law who is a nurse. Everyone was very professional and we were looked after well. The doctors and nurses knew what they were doing , they answered any questions I had and it was a very nice experience.

It turned out I didn't need a transfusion but I was there for three hours and I need to go back there in a few weeks. 

They made sure we were comfortable and fed, they gave all three of us sandwiches and drinks/coffee and the staff had a good sense of humour.

The only blip was when we arrived, I'd been referred so gave reception a letter and they said just go and sit in the waiting room down there and it won't be long. They were right, it wasn't long before my name was called but it was my name being bellowed in a very loud voice down the corridor. So, we got up but we didn't know who had called my name, we stood there but no one said anything. We didn't know what to do. There are two swinging double doors into the assessment area next to the reception and my daughter in law said she'd go and look to find out what was going on, I didn't think she could go in there but she did. We thought we'd lost her as she had been gone for a few minutes. She came back and no one had said anything to her just a few people had looked at her but she was in jeans and a leather jacket. I can't understand how no one asked her what she was doing.

We asked the reception staff what we were meant to do and just then the staff member we were to see appeared. I really don't like the idea of their voice shouting my name all around the place. I feel like the member of staff could have come closer to the waiting room so as not to shout my name and so we knew who said it. in a lot of places they come to the waiting room and say your name and wait for you to get up and take you to where you are going. This would have been better. 

I'm also worried that my daughter in law was able to wonder in on her own and no one noticed, is that normal?

I can't fault the treatment at all, we were there for around three hours and weren't sitting around waiting for people, one doctor would leave and then the next person would see us straight away. You have a big cubicle too with chairs for the people you are with and there were curtains and I was very impressed with the service apart from that security side (any one could have just rocked in) and my name being shouted and the ensuing confusion.
