Der Schmerz

In 1998 the board of the DGSS introduced a computerized documentation system named QUAST (quality assurance in pain therapy) building the foundation for a large, anonymous database that served as a data source for the statistical characterization of clinically relevant profiles of patients in German pain clinics. ⋯ The documented data differ from other population-based data collections. In contrast to common belief there are a considerable number of patients who find access to specialized pain therapy institutions at an early stage of their illness. The hitherto regular use of generic, syndrome-overlapping diagnosis and treatment tools should be reconsidered taking into account the differences found between the main pain diagnosis groups. Lastly, this analysis provides current data on the psychological state of chronic pain patients showing a high degree of psychological distress and underlying the need of psychotherapeutic interventions in the treatment of chronic pain patients.
