"Passed from pillar to post for treatment"

My father has been treated at various points over the past few years for skin cancer - originally his care was provided by the Dermatology team at RCHT. Over the past couple of years Dad seems to have been passed from pillar to post for treatment - sometimes Dermatology, sometimes Max Fax sometimes the Plastics team. As he requires ongoing treatment at each appointment he has been told that his case will 'be discussed at MDT' so that a treatment plan can be agreed - this has yet to happen! Dad was supposed to have a 6 month follow up appointment to check the skin cancer sites that had been treated and to assess the areas that still require treatment - it is now nearly mid December and he still hasn't been given an appointment. My Dad is reluctant to contact the hospital as he now has no idea which department is responsible for his care and is relying on the hospital to make contact with him. I have tried making contact for him (Dad is very hard of hearing so struggles on the phone and is reluctant to be seen making a fuss) but I am told that I can't be given information due to 'patient confidentiality'.

Don't get me wrong, when Dad has received treatment it has been carried out efficiently and the staff have been every thing we could wish for in terms of  professionalism pleasantness and understanding - however I am now very concerned that the disjointed care pathway he seems to have been placed on will have negative consequences for his future health as the skin cancers are not being assessed and potential treatments being delayed
