What to expect
It all started when a daughter asked her father 'Are there any risks?'.
Investigative journalist Charlotte Grieve had a very personal reason to be interested in celebrated orthopaedic surgeon Dr Munjed Al Muderis. Her father had lost his leg almost sixty years before a chance meeting with Dr Al Muderis, who raised concerns about her father's ongoing mobility. The famous doctor told him that osseointegration surgery would keep him out of a wheelchair. Her mother suggested a second opinion. The collision of the personal and professional would spark an investigation that led to a $20 million defamation trial.
Charlotte uncovered serious concerns about the doctor's surgical practice and evidence that he routinely failed to adequately inform patients of the risks involved in his signature procedure. Doctors have a duty of care, but they also legally have a duty to warn. It means that they must warn patients of any risks. When that is not done, vulnerable people have to live with the consequences.
Dr Al Muderis would go on to spend millions trying to prevent Charlotte from warning the public about his failures. Though pressured to drop her investigation, Charlotte stood firm. In the defamation trial, thirty-five of his patients, dozens of doctors, surgeons and health professionals would take the stand, defending their stories, their lives, their truths.
Compelling and masterfully written, Duty to Warn is the inside story of a young journalist fighting to uncover the facts whilst coming up against a powerful individual determined to stop her. It delivers a rare window into legal and ethical reckoning in medicine and in journalism. Ultimately, it is a story about the duty to warn, what it means, and the catastrophic outcomes that can ensue when a doctor fails to uphold their ethical responsibilities.
