Thanks, its just whether I start from scratch with a traditional part time PhD and thesis or if the publication route makes more sense considering what I have already.

I am a lecturer with two publication, both qualitative healthcare research. Same theme with, 30 participant interview in total. Published in reasonable impact journals. Anyone in a similar position gone for a PhD by publication, my thought was I would need at least one or two more similar publication then tie them together in the theses. Is this enough?
