Definition of Nursing (expanded version)
Nursing is a safety critical profession founded on four pillars: clinical practice, education, research, and leadership.
Registered nurses use evidence-based knowledge, professional and clinical judgement to assess, plan, implement and evaluate high-quality person-centred nursing care.
The work of registered nurses consists of many specialised and complex interventions. Their vigilance is critical to the safety of people, the prevention of avoidable harm and the management of risks regardless of the location or situation.
Compassionate leadership is central to the provision and co-ordination of nursing care and informed by its values, integrity and professional knowledge. Responsibility includes leading the integration of emotional, physical, organisational, and cognitive nursing work to meet the needs of people, organisations, systems, and populations.
Registered nurses are decision makers. They use clinical judgement and problem-solving skills to manage and co-ordinate the complexity of health and social care systems to ensure people and their families are enabled to improve, maintain, or recover health by adapting, coping, and returning to live lives of the best quality or to experience a dignified death. They have high levels of autonomy within nursing and multi professional teams, and they delegate to others in line with the NMC Code.

The leadership pillar for some nurses will include management responsibilities.

How you can use the principles
As a nursing professional or nursing student you can use the principles to:
- understand what patients, colleagues, families and carers can expect from nursing
- help you reflect on your practice and develop as a professional
- generate discussions with your colleagues or if you are student with your mentor, tutor or fellow students on the aspects of behaviour, attitude and approach that underpin good nursing care
- identify where the principles are being practised within your organisation, and to identify instances where you think they are not being practised
- see how they relate to a trust’s own set of nursing values.

Professional framework for nursing
The ÂÌñ»»ÆÞ has started a programme of work to co-create an overarching UK wide professional framework for nursing. This is led by the Professional Nursing Committee and in collaboration with forums and fellows.
It will bring together the vast variety of career and competency frameworks across all settings to show the opportunities our profession has, which will support recruitment and retention of the nursing workforce.
