A multidisciplinary approach for the management of patients with chronic pain is now well-established in many countries, especially in situations involving a complex disease process in the sense of a biopsychosocial model. Both the efficacy and cost-effectiveness of multidisciplinary pain treatment programs and their superiority compared to unimodal therapy has been documented in a number of studies, reviews and meta-analyses, in particular for patients suffering from chronic low back pain. ⋯ Furthermore, there is still no consensus on specific therapeutic approaches, the differentiation between responders and non-responders as well as on the tools required for measurement. All these questions will have to be answered by concerted efforts in a multicenter setting.

In Germany, approximately half a million people suffer from cancer pain, which is one of the most common first symptoms of tumor disease in 20-40% of the patients. The prevalence increases during the course of the disease to approximately 90% among patients in a palliative care unit. Treatment in the field of cancer pain is often provided by interdisciplinary teams of different pain or palliative care services. ⋯ There is a great need for the further development of the coordination and networking of these services within Germany, which is regulated by the Hospice and Palliative Act. The cross-sectional curricula QB 13 (palliative medicine) and QB 14 (pain medicine) were implemented in German medical faculties in order to improve integration of cancer pain management into the teaching of medical students. Research in the area of cancer pain addresses clinical topics such as the availability of opioids, but also basic research including genetic variability as a predictor for the efficacy of opioids and the neurobiology of cancer pain.

Pain perception is a complex experience that entails somatic and psychological factors. This is especially true for chronic pain where increasing chronicity leads to a growing significance of psychological factors such as learning and memory processes or cognitive evaluation at the expense of nociceptive processes. ⋯ For the future of this research area, a differential analysis of the contribution of psychological factors to chronicity is important. For a mechanism-oriented treatment, the development of new treatment approaches and the analysis of specific subgroups for a better differential indication of treatments is needed.

In spite of several approved analgesics, the therapy of pain still constitutes a challenge due to the fact that the drugs do not exert sufficient efficacy or are associated with severe side effects. Therefore, the development of new and improved painkillers is still of great importance. A number of highly qualified scientists in Germany are investigating signal transduction pathways in pain, effectivity of new drugs and the so far incompletely investigated mechanisms of well-known analgesics in preclinical and clinical studies. The highlights of pharmacological pain research in Germany are summarized in this article.

The starting point for German headache research and clinical education was the engagement of D. Soyka in the 1970s, which enabled the foundation of the German Headache Society (DMKG) on 28 June 1979 and, some years later, the founding congress of the International Headache Society (IHS) in Munich 1982. As a result of these activities, in 1988 the first international classification of headache disorders was published. ⋯ A specific development in the German headache scene is the establishment of integrated headache centers and reflects the primarily multimodal treatment approach in Germany which contrasts with the settings in other countries. These successful developments are increasingly being undermined by the fact that the low financial support of headache research, for example, by the German science council is causing a decreasing interest in headache research, with the consequence that the clinical education of students as well as young medical doctors shows increasing deficits. The consequence for the future will be a deficit in the clinical care of the population.
