Following "A Hospital Visit", a manual that looks at visiting someone else in hospital and short visits to Outpatients leading up to a stay in hospital, this second manual on staying in hospital looks in more detail at the various clinics and treatments available.    
The signs have been developed to try to visually explain the meaning behind some very difficult and complicated expressions.  The intention is make a stay in hospital less threatening and alien to a patient who has learning difficulties and who is likely to be uneasy and confused.
