Pain is experienced by many patients in primary and secondary care and the assessment of pain is a fundamental aspect of nursing. Community nurses need to possess a strong knowledge base to inform and advise their patients, this in turn enables them to help and empower their patients to effectively control pain with minimal side-effects. This two-part series on pain provides an update on the assessment and management of acute and chronic non-malignant pain. This first part of the series examines how community nurses can recognise and categorise pain and start to draw up a plan of care for the patient. The second part in this series will deal with the management of pain.
