Implementation of ISO 9001 is the same for any type of business including the hospitals, clinics or any other health institution.
You need to get the management buy in for the implementation first and then to assemble team for the implementation. Next step is to perform gap analysis to determine to what extent your company is already compliant with the standard and what needs to be done to achieve full compliance. Here you can find our free GAP analysis tool https://advisera.com/9001academy/iso-9001-gap-analysis-tool/
Then you need to start creating necessary documents and implement new processes and actions in order to be compliant with the standard. For more information, see: ISO 9001 Implementation Diagram https://advisera.com/9001academy/free-downloads/
Once you complete the implementation, you need to conduct internal audit and management review to ensure that your system is fully compliant with ISO 9001:2015 . Finally you can hire certification body to conduct certification audit and issue your company the certificate.
