I think what is being said here is that in the case of a "life threatening" emergency, you better get your body to a hospital as a doctor or clinic will probably not be able to help you much.
If your "emergency" is a cut foot, ripped off toenail, migraine headache, etc. then the clinic or doctor would work just fine.
If you have a pre-existing condition that might suddenly get worse and become a "life threatening" emergency then you might want to take the lack of hospital into account before booking a trip or have a backup plan for emergency transportation should it be needed.
