This article considers two areas of practice that are fundamental to the provision of high-quality nursing care for people experiencing acute pain: the initial recognition of pain, and the formal assessment of pain. The initial recognition of a patient’s pain is a subject that is frequently overlooked in the literature. However, if nurses are unable to identify that a patient is experiencing pain, then a formal pain assessment may not take place, which in turn negatively affects the quality of any subsequent pain management. This article explores some of the barriers to the initial recognition of pain and examines how a formal pain assessment can support optimal patient care.
