[Structure quality of independent physicians for pain management--is there a standard?]

Evidence based standards for structure quality in out-patient management of chronic pain states do not exist. Therefore we tried to evaluate if german standards for outpatient management of chronic pain states which are based on opinions of experts for pain management influence the outcome quality of independent physicians for treatment of chronic low back pain.

35 independent physicians, selected on a voluntary basis from 2100 physicians of a bavarian greater district with 1,6 Mio. inhabitants, and one outpatient treatment facility for pain patients of the university of Erlangen-Nuremberg have been evaluated by questionnaires. Questions examined certain structural conditions of the treatment facility as compared to german guidelines for outpatient treatment of pain patients ("Schmerztherapievereinbarung"). 157 patients suffering from chronic low back pain documented before and after a treatment interval of 6 months their pain intensity during the last 24 hours (numeric rating scale), the interference of pain with daily living (german version of the Brief Pain Inventory) and their quality of life (SF-36). Pre-post changes have been used as parameters for outcome quality.

Neither baseline data nor pre-post differences of outcome parameter did correlate significantly with the scores of structure quality (17-71% of maximum) of the treatment facilities. However, multimodal therapy programs have not been used for pain management.

Structural indicators of german guidelines for outpatient treatment of pain patients ("Schmerztherapievereinbarung") are not sufficient to improve outcome quality of patients with chronic back pain. Multimodal therapy programs have been shown to be effective in chronic back pain and should be implemented in the guidelines.
