Epidemiology of chronic pain - an investigation in 5 medical practices

Background and methods: The aim of this study was to get more information about the prevalence of chronic pain in different practices of home physicians. 900 patients of five different specialists (general medicine, internal medicine, neurology, orthopaedics, surgery) in the german town Bochum were investigated with a questionnaire about chronic pain. Chronic pain was defined as a continuous or intermittend pain of longer duration than six months. Results: 36% (328 patients) of all investigated patients had chronic pain due to this definition, twice more women than men. The four most frequent localisations of chronic pain were the back, the head, the joints and the legs. 15% of the patients with chronic pain were retired or going to retire due to their chronic pain. Orthopaedics were the most frequent physicians visited in the past. Only 5% of the patients had a psychological therapy and only 1% were treated in a pain clinic. The primary treatment strategies of the chronic pain were physiotherapy and drug therapy. 30% of the patients did not have any pain relieve by the past treatment strategies. Conclusion: Patients with chronic pain are a frequent and important problem in practices of home physicians. The high frequency of patients with chronic pain in practices of specialists demonstrates the necessity of a special qualification also on this level of our medical system.
