A hand surgeon is referred for peer review for a case of a wrong-site surgery.

 This is because peer review in medical practice is a process by which a committee of physicians examines the work of a peer and determines whether the person under review has met the standards of the profession. The committee member should have a similar level of expertise to the person under review. Therefore, a plastic surgeon with comparable training to the hand surgeon would be the most suitable choice. They would have the necessary knowledge and experience to accurately assess the hand surgeon’s performance. Please note that this is a general answer and the specific answer may vary depending on the context and specific rules of the medical institution. Always consult with a professional or trusted source when making important decisions.
