Old dwp decisions as evidence

Can you use past dwp decisions as evidence for esa claims? Ive recently found an old decision letter where the health professional says they recommend support group as Ive got severe functional disability and my condition is unlikely to improve in the longer term although theyve said work is unlikely for 2 years. Ive got my telephone assessment coming up and I didnt include this when I sent my ESA50 form back in but Im just anticipating in case an MR is needed or i need to go to tribunal. Im also wondering if i should be having a re assessment under the circumstances with those findings in the report even though it was a few years ago but not sure. My conditions have got worse and I have developed a few more since that report.

Thanks Chris also wondering if its worth reading this out as additional evidence while on my telephone assessment

Yeah i keep feeling panicked and then think its all I can do is my best. Just one more quick question if it’s a telephone assessment can they ask for it to be a video call? Im not planning on getting dressed out of my PJs (too much info) as theyve said they could ring at 9 and I dont normally manage to dress before ive mobilised later in the day unless I have help and it’s a good day. It’s bad enough dealing with this first thing as it is. Just dont want them to ask for a video call half way through or something.
