Mistakes made in Hunter Hospitials

Concerns have been raised after Hunter New England Health admitted there were fifteen major mistakes made in the region's hospitals last year.

In one instance, a baby was given another mother's breast milk, while some patients were given the wrong scans and seven patients were given medication they were allergic to.

The Heath Service says while the mistakes were regrettable and distressing, there were no adverse outcomes from the incidents.

The Medical Error Action Group says it's pursuing a number of cases with the region's health authority.
