I recently received my PIP review form through the post, and all of the feelings of dread, fear and anxiety that I encountered when I first applied for it, came flooding back, because the process is often far too rigorous, and stressful for many disabled people because it is often followed by health assessments that don't often go in the applicants favour, that they end up having to go through a lengthy appeals process following them.
I'm sure that for the majority of people receiving PIP, their lives depend on it (as does mine) and the thought of possibly having their payments stopped or disrupted (even if it is temporary, due to the PIP review process) could cause a lot of people a great deal of anxiety and distress.
Furthermore, I can't quite understand why those of us with a lifelong inherited disability (for example, a disease such as Sickle-Cell/Trait) and receives PIP, has to have their application for it reviewed every 3 years, when it is clearly evident that their condition, is never going to change or improve, not only because it is genetic, but also because conditions such as these gets worse, and not better over time., and so therefore, I believe that their PIP payments should just continue throughout the duration of a person with these conditions lifetime. They shouldn't have to go through further stressful health assessments by the DWP in order to prove that they are still ill in order for their payments to continue - a Doctors note with evidence of the persons medication continuity should suffice in my opinion.
In sum, I think that alongside the Universal Credit system, the PIP application/review process and system also needs to change too.
