A GP who tried to blame a pharmacist and nurses for her ongoing prescribing of excessively high doses of morphine has had her medical registration cancelled for six months.

Aged-care GP Dr Judith Silberberg was reprimanded and found guilty of professional misconduct in the NSW Civil and Administrative Tribunal over prescriptions for 14 end-of-life palliative care patients.

According to evidence presented to the tribunal, parenteral doses of morphine administered to patients were 3-4 times in excess of the conversion rate for oral to parenteral morphine.

While Dr Silberberg admitted she had made a fundamental error when titrating the dose, she said it was “disappointing” that “not once” had the pharmacist or nurses questioned her incorrect conversion, despite it being a recurring error.
