IntroductionThe efficacy of opioids has been proved and several guidelines and expert panel-based recommendations regarding the use of opioids in different pain syndromes are available. Nevertheless, undertreatment of pain with strong opioids was reported in previous studies. It was shown that physicians' lack of knowledge, their concerns and misconceptions about the opioid use and the controlled substances regulations that govern the prescriptions of opioids occasionally contribute to insufficient pain treatment. This study was designed to evaluate German physicians' knowledge and their concerns about the use of opioids.MethodDuring a postgraduate course a questionnaire was completed by German physicians specializing in pain therapy.ResultsA total of 226 physicians completed the questionnaire (response rate 57%). Many of them had poor knowledge of the WHO recommendations for the treatment of cancer pain including the WHO analgesic ladder. Deficiencies in the knowledge of pharmacological aspects and controlled substances regulations were revealed. Many physicians would prescribe strong opioids for non-opioid-sensitive types of pain. The concerns regarding opioid therapy included adverse effects and addiction. In contrast to earlier findings the German controlled substances regulations no longer seem to be a barrier to the prescription of opioids in the treatment of chronic severe pain since they were changed in 1998. As a result, the lack of knowledge and the physicians' concerns about the use of opioids as shown in this survey may likely lead to an insufficient treatment of patients suffering from severe chronic pain.ConclusionIt is necessary to improve the medical students' education and the physicians' postgraduate training regarding principles of pain management such as the WHO guidelines for the treatment of cancer pain. A better knowledge of important pharmacological aspects of opioids should help to reduce physicians' concerns about the use of strong opioids. Nevertheless, improvement of physicians' skills in pain therapy is only one aim in a multidisciplinary concept in order to improve patients' pain therapy.
