Wilson v Tier

Wilson brought an action against Tier, an oral surgeon, claiming compensation for a medical negligence incident involving a wisdom tooth extraction that allegedly resulted in a deep neck space infection, which the plaintiff claimed was not diagnosed and treated in a timely manner by the defendant. The case was heard in the Supreme Court of New South Wales. The plaintiff sought damages for physical injury, psychological harm, and loss of income, contending that the defendant's failure to diagnose and treat the infection promptly led to a more severe condition. The court was required to decide whether the defendant breached the standard of care owed to the plaintiff, whether such a breach caused the plaintiff's injuries, and if so, what the appropriate quantum of damages would be.

The court examined the evidence presented by both parties, including expert opinions on the standard of care and causation. The experts generally agreed that the defendant failed to meet the required standard of care, which included the necessity of diagnosing and treating the infection promptly. Regarding causation, the court considered whether earlier antibiotic treatment would have made any difference in the plaintiff's outcome. The court found that the evidence indicated that while earlier treatment might have mitigated some of the plaintiff's injuries, it would not have entirely prevented them. The court also considered the psychological and psychiatric reaction of the plaintiff to the treatment and the difficulties in determining the individual heads of damages. The court concluded that the plaintiff's psychological and psychiatric damages were indeed caused by the treatment and not merely a reaction to the underlying medical condition.

The court found in favour of the plaintiff and awarded damages for medical expenses, loss of income, and psychological harm. The court recognised the significant agreement between experts on contentious issues and considered it in determining the appropriate quantum of damages. The court emphasised the importance of timely diagnosis and treatment in preventing severe complications and highlighted the need for medical practitioners to adhere to the standard of care expected in their field.
