The Care Quality Commission has also called for further action on the amount of time it takes for children to be seen by doctors.
The report says:
"Registration of children in the A&E department was not ideal as they had to queue with adults at times and following assessment out of hours , the children's waiting area was not visible to staff. The A&E reception area was crowded at times and we saw sporadic and changeable A&E assessment practices in the front reception area. It was difficult to visualise all parts of the waiting area. This could mean that a deteriorating patient may not be noticed quickly which is a concern.
"Children who attended as out patients for dermatology, orthopaedic and Ear Nose and Throat appointments were not seen in the dedicated paediatric out patient clinic. This was not good practice and is against NICE guidance."
