When hospitals any-o-how recruit nurses who need patients help with interpretation and spelling, it's still not so critical if they are qualified.
With doctors who need to communicate with patients to form diagnoses, it is a different matter.
Already some local doctors cannot communicate with uncles and aunties except in the case where the patient can speak the doctor's mother tongue.
If the hospital any-o-how recruit doctors, we run a greater risk of misdiagnoses.
