Critical look at the clinical practice guidelines for allergic rhinitis

SummaryAllergic rhinitis (AR) is a major health concern and numerous guidelines have been developed to standardize and to improve the management of this disease. As in many other areas of medicine, the methodology of the AR guidelines has evolved from opinion-based to evidence-based medicine. Although evidence-based medicine has many benefits, it also has limitations and cannot cancel the value of the individual clinical expertize.More important than the methodology of guideline development is the efficacy of guidelines to change patient and physician behaviour and to improve clinical outcomes. At present, however, studies on the effectiveness of guidelines are few. The International Consensus on Rhinitis from 1994 is the only guideline for AR that has been assessed for its effects on health outcomes. Furthermore, there is a lack of valid and reliable instruments to assess physician's and patient's attitude towards and compliance with guideline recommendations.There is no single effective way to ensure the use of guidelines into practice, but a carefully developed and multifaceted dissemination and implementation strategy and targeting and adapting guideline recommendations to the local and individual level are key elements. The final and most important step of putting guidelines into practice occurs at the level of the patient. Patients should be considered as effective partners in health care. Education of the patient and efforts to change patient's behaviour can maximize compliance, increase satisfaction and optimize health outcomes.
