The reality of adherence to rhinitis treatment: identifying and overcoming the barriers

Medical advances have allowed many patients with chronic diseases to lead relatively normal lives, but disparity between patient perceptions of "normal" and therapeutically defined disease control contributes to lowered adherence to treatment. This disconnect is greatest in diseases such as allergic rhinitis (AR) in which patients experience varying symptom severity over time-from asymptomatic periods to episodes of severe illness. This study was designed to evaluate the concept of adherence as applied to patients with AR. We reviewed the published literature. Adherence (or nonadherence) is an active process involving decision making on the part of the patient. Poor adherence with therapy can be the major barrier to achieving disease control, and the "on again, off again" approach to AR treatment embraced purposely by some patients may contribute to symptom lability, disease exacerbations, and higher costs. Evidence from surveys suggests that although specific educational interventions can temporarily improve adherence, in the long term most patients eventually revert to their former behavior. The available data suggest a need to reappraise how we address adherence with therapy in patients with chronic diseases with variable symptoms such as AR. The question is not just whether patient behavior can conform to recommended treatment plans, but whether it should. Experience suggests that successful strategies will be brief, easy to use, and capable of being tailored to individual patients in diverse clinical settings. Increased flexibility with medications is a corollary, particularly when patients are relatively asymptomatic (i.e., considered in control).
