title: [Outcome-quality of treatment for headache on primary care conditions].
abstract: BACKGROUND
  Little is known about the outcome-quality of treatment for headache on primary care conditions in Germany.
  
  
  METHODS
  All physicians (2100) of middle franconia, a bavarian greater district with 1,6 Mio. inhabitants, involved in outpatient management were asked to include consecutively patients in the study which suffer from migraine (at least 2 attacks/month) and/or tension type headache (at least 8 days/month) of at least 4 weeks duration. Before and after a 6 months interval patients documented the following outcome data in a questionnaire: pain intensity during the last attack (numeric rating scale), pain dependent disability (Brief Pain Inventory, German version), health related quality of life (SF-36, German version) and depressivity (Allgemeine Depressionsskala). The pain chronification state (Mainz Pain Staging System) has been assessed by the physician. Therapy was not standardized and included the natural spectrum of medicamental and non-medicamental therapy of headache. Agreement of therapy with recommendations of the "Arzneimittelkommission der Deutschen Aerzteschaft" has been assessed.
  
  
  RESULTS
  24 physicians participated in the study. Pre-post-data of 80 patients (46+/-14 y) could be analysed. Initially 67% were classified in pain chronification state I, 27% in state II and 6% in state III. Medicamental therapy agreed with recommendations in approximately 50% of patients, non-medicamental therapy has been used rarely. The pain intensity, pain dependent disability, depression and quality of life improved significantly. 45% and 55% of patients improved in at least 2 of 6 outcome-parameters by 30% of baseline value or by half standard deviation of the corresponding pre-post-differences, respectively. The latter outcome-measure reflects a medium effect size.
  
  
  CONCLUSIONS
  On primary care conditions about 50% of patients suffering from migraine and/or tension type headache (predominantly low chronification stae) perceive a therapy effect that corresponds to a medium effect size.
