Improving Outcomes in Adults with Atopic Dermatitis: Part I – Impact of Nonadherence

figure 1

Effective treatments for adults with atopic dermatitis (AD) have been available for decades, and yet clinicians and patients alike struggle with achieving adequate outcomes. Poor adherence is a critical factor limiting patients’ treatment outcomes. Even patients with extensive, lichenified AD plaques who are admitted to the hospital and started on 0.1% triamcinolone topical ointment improve rapidly over just a few days. The success of hospitalization is likely due to strict application of treatment rather than the hospital environment itself.1,2  

Medication nonadherence is pervasive throughout healthcare, with nonadherence rates varying from 15% to 93%.3 The annual cost to the United States healthcare system due to nonadherence is $300 billion, which is comparable to the total gross domestic product of Denmark.4 Adherence to topical medications is dismal, with adherence rates declining to 32% over 8 weeks in atopic dermatitis and 51% in psoriasis.5,6 These rates were measured using electronic monitors in medication containers and were vastly different than patients’ self-reported adherence rates of greater than 90%.6 Even highly effective targeted biologic therapies are often not used optimally. Over half of patients prescribed injectable biologics do not fill their prescriptions within the first month of their appointment, and only about a quarter of those patients fill their prescription within 6 months.4

If we are dispirited about treatment failure, imagine how disheartened our patients feel. In order to provide the best care for our patients and give them the best chance at successfully managing their AD providers need to utilize specific approaches to improve adherence and outcomes. A pyramid model can be used to describe the various approaches to patient adherence (Figure 1).7 The next 3 parts of this 4 part series will address these levels of the pyramid: (1) Foundation, (2) Basics and (3) Advanced approaches.
