Ms Karissa Marks – Registered nurse – Disqualification

27 September 2021

The Health Care Complaints Commission (Commission) prosecuted Karissa Marks, formerly a registered nurse, before the NSW Civil and Administrative Tribunal (‘the Tribunal’). The complaint alleged that Ms Marks was guilty of unsatisfactory professional conduct and professional misconduct in relation to her treatment of two patients in a correctional centre in 2019. It was alleged that Ms Marks failed to conduct an appropriate assessment of a 50 year old patient and failed to transfer him to hospital. It was also alleged that, eight days later, Ms Marks failed to provide appropriate care to a 26 year old patient who was suffering from a self-inflicted neck injury.

On 23 September 2021, the Tribunal decided that Ms Marks was guilty of unsatisfactory professional conduct and professional misconduct. The Tribunal was critical of Ms Marks’ lack of care and concern in dealing with both patients with serious health conditions. Ms Marks also failed to complete necessary documentation and communicate with the nursing team. The Tribunal had grave concerns for her ability to practice nursing in an appropriately safe manner.

Ms Marks had previously surrendered her registration. The Tribunal ordered that, if she were still registered, it would have cancelled her registration. Ms Marks is disqualified from being registered in the nursing and midwifery profession for a period of two years.
