My experience is that the polyclinic docs don't check the
electronic medical records. But the hospital side definitely do,
namely the A&R & the specs.
Technically, still can "bluff" lah, if you go to different polys.
They still rely mostly on written dockets there, though I know the
hospital side will send post-visit feedback back to the poly for
record purposes. That said, the GPs increasingly like to be just
GPs, & write referral letters to direct patients onto
specialist clinics instead. (In your case, a skin spec.) No more
straightforward calamine lotion anymore, for example, not until
after undergoing blood tests for a wide range of possible
illnesses.
You'll get new medical appointments for sure, but likely only a
time sheet from the GP. And, if you ever meet the spec, they'll see
your background & can then ask you why you're seeing so many
GPs, or why didn't turn up for the spec appointment -- possibly
passing a stapled note along to your MO, if they're
suspicious.
My tip is to continue seeing the spec, since your rashes are for
real. (But shouldn't they have pinpointed your allergy yet?) Very
costly if it's continued treatment, though. Just to see the spec
each time, it's $20 if you're subsidised & at least $50 if
you're not (before other charges).
