Developing and implementing a pain management benchmark.

For most patients, pain is an inevitable part of the cancer journey. Pain may be acute or chronic, it may be related to the disease process or to treatments such as surgery, radiotherapy or chemotherapy. For 80-90 per cent of patients with cancer, effective pain relief could be attained using the analgesic guidelines outlined by the World Health Organization (1996). However, in routine practice this is not achieved (Portenoy and Lesage, 1999), which highlights the need to review and improve practice continuously.
