As someone who has worked for over 30 years as a GP, let me say that telephone consultations only work for (at best) 50% of consultations. We tried it all.... search on-line for "Doctor First" to see how it might happen. Half of the consultations need an examination, so you lose time on the phone / Skype and then do the normal consultation. Being too available caused consultation figures to rocket ( hello doctor, I've got shampoo in my eyes, what can I do? ) and we lost an experienced GP for 6 months with stress.
Increasing litigation means that no doctor wants to take a risk, so the fail-safe is to examine patients to at least put yourself in a position to make a diagnosis which is defensible in court /coroner's court.
