Pain services and palliative medicine - an integrated approach to pain management in the cancer patient.

The vast majority of cancer patients will experience pain during the course of their illness. Thankfully, in most instances, the consistent application of analgesic guidelines, tailored to the unique needs of each individual patient, will deliver a satisfactory outcome. These guidelines recommend the skilled use of analgesic medications, often in conjunction with a range of adjuvant therapies as may be required. Despite the consistent and rational application of such strategies, it is recognised that a small but significant proportion of cancer patients continue to experience more refractory pain. In addition, these patients may experience a plethora of unwanted dose-limiting side effects associated with their analgesic medication, sometimes even at low dose. All such patients with more complex and refractory pain syndromes require a more comprehensive review and many will require interventional therapy and/or adjuvant approaches. Unfortunately, the availability and accessibility of such services are variable. Even in circumstances in which palliative medicine and pain services co-exist in the same region, there may be poor integration between the two services. Each specialty area holds a unique set of skills and competencies, yet there is considerable overlap. Patient care and outcomes will be enhanced by establishing more formal relationships between these two specialty areas.
