Life / No Health care in Poland for the elderly? Insulin injections. [8]

Hello Members

My daughter of 5 would finally like to have a vacation with her father.
She would like to bring her mother with her as she is to small to be without her mother.

This means grandma would be alone in Poland and needs a insulin injection twice a day and can not be alone and is unable to travel.

My ex has looked into this if there is help available from the Health System for 2 weeks.

Apparently she was told this is not there problem. And do not offer such help when there is any other family member alive who could do this.

The other living family member is also very far away and elderly and not able to or expected to help.

Is the health care system so bad in Poland??
What other options are available?

Thank you.
