The NMC has released the revised Code on 29 January.
The Code: Professional Standards of Practice and Behaviour for Nurses and Midwives builds on the current version, published in 2008, with some revisions based on results from consultation.
The revised Code is made up of 25 standards rather than 114, following feedback from nurses and midwives that the code was too long and difficult to follow.
Instead of being based around five statements, it will now centre on four themes. These themes are 'prioritise people', 'practice effectively', 'preserve safety' and 'promote professionalism and trust'.
The Code was updated to ensure that it is line with the new model of revalidation being introduced at the end of 2015.
Jackie Smith, chief executive and registrar of the NMC, said: 'The Code sets out the professional standards for nurses and midwives. When someone joins the NMC's register, they are committing to uphold these standards when they practice. Public expectations of care have changed radically since the Code was last reviewed in 2008. It is essential that the Code reflects patients' needs, modern healthcare practice, and the recommendations of reviews such as the Francis Inquiry.'
Some sections have been reworded such as the one on social media to reflect nurses needs.
The new Code will be effective from 31 March 2015. The NMC will distribute a printed copy to all nurses and midwives registered with the NMC as of 9 February 2015. Copies can also be downloaded from the NMC website.
