This study explores Australian clinical nurses' and midwives' familiarity with a new code of conduct and understanding in what ways the code is important for nurses as they carry out clinical practice.Codes specify the expectations of nurses' responsibilities, legal requirements, behaviour and conduct. Being familiar with the code is central to being a professional nurse or midwife. As nursing continues to advance, updating the code is crucial to maintain professional and safe practice.This project utilized a cross-sectional descriptive design.A survey was developed incorporating Likert-type scale assessments of the 7 value statements from the 2018 Australian Nurses' Code of Conduct for familiarity and importance. The survey included open-ended questions to elicit clinical nurses' experiences of conduct breaches, opinions regarding usefulness and relevance of the code for current practice. Data were collected at an acute care hospital in Sydney during January 2018.Significant differences relating to cultural and patient-centred approaches were revealed in the study. The new value involving the role of research was least understood and ranked least important by nurses and midwives. Professional 'integrity' resonated with participants when considering the behaviour of nurses, and short, unambiguous values were the most popular. Additionally, a substantial number of participants had no knowledge of the code or were not aware of the recently revised version.A code of conduct provides structure and guidance for workplace values and principles. A respected code is important to the nursing profession to help prevent inappropriate and incompetent behaviour and as a guide for nursing performance. Nurses in this study claimed the code was highly relevant to their work as a nurse and was incorporated into their daily practice.
