As expected there seems to be a bit of conflicting advice about these changes. From what I understand it will have absolutely no impact on tourists or expats, unless that is they get involved in anti government demonstrations. If you get taken to hospital you will be seen immediately and if involved in an accident but lucky enough to have a doctor passing at the time, that doctor is able to treat you until the ambulance arrives.
The legislation seems to be a blunt instrument, but that's how they do things here.
