A doctor says there is a “culture of exclusivity” and he was the “victim of an insidious hate campaign” when he tried to support a 24-hour Royal Adelaide Hospital specialist service in the lead-up to a rostering blunder. On Wednesday, Flinders Medical Centre radiologist Dr Steve Chryssidis told State Coroner Mark Johns about the “toxic” environment in the RAH radiology department. “I felt that I was the victim of an insidious hate campaign,” he said. “There was an undermining culture of exclusivity and the environment was toxic — it was destructive. “I struggled in that environment and there was no acknowledgment of the efforts I had made to support the service.” Dr Chryssidis was called in to the RAH to perform clot retrievals on stroke patients Michael John Russell, 60, and Leslie Robert Graham, 87, whose deaths are now the subject of a coronial inquest.
