Chronic low back pain: course of disease from the patient’s perspective

Chronic back pain often leads to permanent disability and—apart from significant human suffering—also creates immense economic costs. There have been numerous epidemiological studies focussing on the incidence and the course of chronic low back pain. Less attention has been paid to the impact of subjective perception of the disease and the degree of healthcare use of these patients. The aim of this study was to gather data about patients with chronic low back pain and compare these data with patients suffering from chronic pain in other body regions. The first 300 pain questionnaires collected by the interdisciplinary pain centre at the University Hospital in Freiburg between January 2000 and September 2001 were analysed. This pain questionnaire is a modified version of the pain questionnaire of the DGSS (Deutsche Gesellschaft zum Studium des Schmerzes—German Chapter of the IASP). It collects demographic and socioeconomic information, as well as information regarding the course of the disease, and the subjective description of pain and the pain-related impairment. The subjective view of the course of disease, shows differences between patients with low back pain and patients with chronic pain of other origin, particularly regarding physical strain as the assumed cause of pain, but also regarding the frequency of prior treatments and cures. The subjective perception of the course of the pain disorder in patients with low back pain compared to patients with chronic pain in other parts of the body shows differences mainly related to the capacity for physical exertion. The frequency of ineffective prior treatments and cures underlines the necessity for early initiation of effective pain treatment aimed at prevention of the pain disorder becoming chronic
