Reflection is an essential aspect of nursing practice that facilitates continuing professional development and practice improvement. Critical reflection is a more in-depth form of reflection and can be described as a creative, dynamic and transformative learning process that enhances practice by promoting self-awareness and critical thinking. Older adults often present with complex and multiple healthcare needs. Engaging in critical reflection can assist nurses to provide the high-quality, person-centred care required to meet those needs, support older people to retain their independence and enhance their well-being. This article discusses critical reflection within the context of nursing older people and describes various models that can be used to support the reflective process. The authors use a practice example to illustrate how using critical reflection in practice can enable nurses to develop a deeper understanding of themselves and use what they have learned to enhance their delivery of person-centred care.
