Basic scientists have developed a wealth of knowledge of pain mechanisms and possible modalities that may modify these to achieve relief of pain. However, it remains frustrating that translation from laboratory experimentation to human therapy leaves many potential treatments wanting. In part, the relative failure of putative treatments results from the complex biopsychosocial aetiology of pain, of suffering and of interpersonal response differences in humans. Thus effective clinical management of pain requires skilled assessment of each patient, often by a multidisciplinary team, good communication, evidence based knowledge and experience. Papers reporting scientifi c advances and results of therapeutic trials, as well as systematic reviews, provide tools for management of pain. These tools require skilled application by a broad range of experienced practitioners to achieve optimal results for patients. An essential resource is an up to date textbook written by experienced scientists and clinicians which may also be used as a ‘bench book’. To be effective, such a volume must be broad ranging, clearly written and offer excellent indexing and bibliography. The Oxford Handbook of Pain Management provides just such a resource. Robert W.

This page intentionally left blank vii Preface Pain remains an all too common feature of our lives and its alleviation represents a ‘Grand’ challenge for healthcare practitioners. Although we have limited diagnostic tools, imperfect treatment options and fl awed structures for their delivery there is much that can be achieved through multidisciplinary and holistic practices which can achieve the best out- comes in the treatment of both acute and chronic pain. This book stemmed from our mutual perception that too few people working in healthcare were privy to the broad range of approaches that were useful in the management of pain. There will never be enough pain specialists and practitioners to meet the needs of all the patients who suffer in this way, thus for this knowledge to be effective it must be disseminated beyond ‘centres of excellence’ down to the shopfl oor. As we have noted, effective pain management often requires a multidisciplinary approach yet the time spent learning about pain in medical school and nursing, physiotherapy, and clinical psychology training is limited and is often limited to a narrow perspective. So it seemed appropriate that we should attempt to collect and share current knowledge about the management of pain from a broad range of viewpoints to support new clinicians, and other colleagues across the world. We felt that to be most useful this information source needed to be concise, to be quick and accessible, something that could sit in a pocket or on a nearby shelf. It is intended to be a pointer to good practice, giving key, immediate guidance. Practitioners have cannot hope to craft effective management plans based on the avalanche of information pouring daily through their letter boxes and in trays, rather they need distilled wisdom from a range of sources. In an attempt to meet this need we conceived the Oxford Handbook of Pain Management . In places this book provides more than most clinicians will need at the coalface, and there is inevitable repetition of some common themes, but we hope that the core information is presented in a way that will encourage thought, help with decision making and provide starting points for more detailed consideration. We all continue to learn (often from our patient’s experiences) and the fi eld of Pain Management is constantly evolving. We have enjoyed collating our author’s insightful contributions that have provided many different perspectives, and take this opportunity to thank them for their patience. This book has been a long time coming but, hopefully, is all the better for it. ‘ The greatest mistake in the treatment of diseases is that there are physicians for the body and physicians for the soul, although the two cannot be separated ’.
