Primary care
In most countries this means general practitioners, dentists, opticians and pharmacists. Emergency departments dont expect people to be checked out first.  Physician assistants, physical therapists, or a nurse may expect people to be sent to them by a doctor in some places.  If people are paying for their own treatment they may be able to go where they want, but in a public healthcare system there are usually more controls.  In less developed countries people may be used to going to hospitals for all their problems.
