At the moment I'm leaning towards something to do with the Liverpool Care Pathway, which is a plan of care that can be implemented during end of life care. It usually means no active treatment is given but there can be discrepences about what is 'active treatment'.
I need to have a look around and see what articles and research papers I can find before I narrow it down but I'm going to start looking soon so that I don't put too much pressure on myself and tehn panic because I've not have enough time !
