The issue of regulation of scope of practice (SOP) has recently been highlighted through the high-profile case of New South Wales-based neurosurgeon, Mr Charles Teo and specifically the finding of ‘unsatisfactory professional conduct’ by the NSW Health Care Complaints Commission (HCCC) in Teo, Charles (2023) NSWMPSC 2 (12 July 2023). The HCCC decision went to two issues in Teo’s practice: (1) his decision to perform a surgery not within the SOP of his profession [at 238]; and (2) his failure to gain patient informed consent for that surgery [at 245]. This paper explores the findings against Teo with respect to SOP and recommends a nuanced approach to the regulation of clinical innovation and SOP evolution.
