Why do they need to waste time dictating a letter, having it typed up, posting it, and then at the other end, handing incoming post, scanning it, filing it, etc.
It's all so antiquated.
Why not a simple app based/online "tick box" system where all the background information is either "pinged" across or sent via an e-link, with tick boxes of reason for referral, and maybe a small "blank text" box where the referral can make some brief additional comments that can't be communicated by box ticking?
As it is, they seem to spend more time on drafting some childish letter with "codes" to give a character assassination and then, usually send it with no actual details, such as test results, etc.
When my OH was referred by his haematologist to a different hospital specialist for a stem cell transplant, the referral letter was an absolute joke. It was just a couple of sentences - first the usual meaningless waffle of him being a pleasant gentlemen, and then and very brief sentence as to what he'd been diagnosed with.
When we saw the consultant, he had nothing - no test results, no scans, no x-rays, not even a run down of the treatment already given (chemo etc). Complete waste of a consultation. All he knew was the type of cancer and that he was a pleasant gentlemen!
