She was asked by reporters last month why she was going ahead with a trial, which is set to batter and break some of the fundamentals of safe healthcare.
“We have already been running a trial on [pharmacists prescribing antibiotics] for UTIs,” she replied. “And I believe that this has been very successfully applied.”
So what was this belief based on?
