The registration standards do not include any specific restrictions for the registration of medical professionals, who suffer from mental or physical health issues, unless ‘The practitioner has placed the public at risk of substantial harm in the practitioner’s practice of the profession because the practitioner has an impairment.’ This is rarely the case. Refer to: http://www.medicalboard.gov.au/Registration-Standards.aspx
In reality, many medical professionals with mental health issues continue to provide a high standard of patient care, but sometimes at the expense of their own health. Clearly, it is essential that any practitioner with a mental or physical health condition has their own treating practitioner, who will objectively assess their fitness to work.
