Applying Stress and Coping Theory to Understand Diuretic Adherence Experiences in Persons with Heart Failure.

Despite the benefits of diuretics for treating the symptoms of heart failure (HF), patients may report side effects and intentionally not adhere to diuretic regimens. Positive internal motivators, such as positive emotions, may benefit individuals in their adaptation to medication-related stress. However, there has been limited study of these potential motivators in those with HF. Using a descriptive qualitative approach, 82 adults taking diuretics for HF were interviewed. This study applied stress and coping theory to understand the diuretic-taking experiences of patients with HF. Data analysis revealed three themes: (a) diuretics are bothersome, (b) staying positive in the mid of hardship, and (c) adapting to endure. Findings suggest that adherent participants stayed positive amid the perceived hardship, maintaining resilient and grateful attitudes. Adherent participants adapted to bothersome diuretic effects and utilized creative strategies. More research is needed to understand the relationships between resilience, adaptive coping, and diuretic adherence.
