Irect Access: Appropriateness of referral from General Practitioners and requirement of Ear, Nose and Throat follow up.

The dissertation is regarding GPs who refer a patient to an audiology clinic. They refer a patient who they feel may have a hearing loss. I have attatched the protocol for the dept and have then put the stats that i took for 50 patients in december 2005 and added them up and also wrote down what the different numbers etc mean. I would like the introduction to be about hearing and the physiology and then i also need some statistics done which ever the writer feels is most adequet. As its a dissertation it needs to set out in that order.
the writer can find there own, there is no required referencing needed.
