Our systems must be different from yours. We have nurses with a good education who have a lot of knowledge.
And we have caregivers (in Dutch its ziekenverzorger, google translated this as nurse too. I think caregiver is a better translation). Caregivers have less medical knowledge and help the patient to shower, make the bed etc. We have a shortage of caregivers with a diploma especially in homes for elderly who are not in hospital but in a nursing home bc they are far too needy to be able to live independently.
So our government allows helping hands for simple tasks under supervision. If someone has worked as a caregiver under supervision for several years, they don’t get a diploma but a certificate and can work without supervision for regular tasks with such a certificate. Because of the large number of mistakes the nurses and doctors got suspicious. And thats how the police got involved.
