Strategies to enhance patient adherence: making it simple.

The problem of poor patient adherence has been extensively researched, but the rates of nonadherence have not changed much in the past 3 decades. Healthcare providers play a unique and important role in assisting patients' healthy behavior changes. We conducted a narrative review of the current literature to help providers become more familiar with proven interventions that can enhance patient adherence. We then grouped the interventions into categories that can be remembered by the mnemonic "SIMPLE":1. Simplifying regimen characteristics; 2. Imparting knowledge; 3. Modifying patient beliefs; 4. Leaving the bias; and 6. Evaluating adherence. Chronic lifestyle behavior change often requires a combination of all the aforementioned strategies. We suggest a conceptual framework, which calls for a multidisciplinary approach with the above strategies in the context of a healthcare team and system-related factors. We hope that this framework would not only help design scientifically proven interventions, but also reduce the time and cost involved with implementing these strategies in a healthcare setting.
