The aim of this paper is to identify the major barriers hindering adequate pain management and critically review interventions aiming to overcome them. We searched relevant literature on PubMed published between January 1986 and April 2007. The most frequently mentioned barriers for both patients and professionals were knowledge deficits, inadequate pain assessment and misconceptions regarding pain. Four interventions were identified: patient education, professional education, pain assessment and pain consultation. These interventions were never combined in multidisciplinary study protocols. Most RCTs included small groups of patients and reported no power analysis. Studies on professional education and pain assessment did not evaluate patients' outcomes. In 5 of 11 RCTs on patient education, pain intensity decreased statistically significantly. In two RCTs on pain consultation, patients' pain decreased statistically significantly, although the adequacy of pain treatment did not change. In conclusion, international guidelines on multidisciplinary interventions in pain management are partly substantiated by clinical trials.
