The current prevalence of heart failure in the United States is 6.7 million, while the projected prevalence is 8.5 million by 2030. The average client with heart failure has poorer self-care status than the acceptable norm, yet self-care is the foundation of treatment and the key to improved outcomes and reduced disease burden in heart failure. Nurses providing health education can help clients with heart failure learn and perform adequate self-care using the teach-back method, a method recommended by the Agency for Healthcare Quality and Research that has been shown to improve self-care in clients with chronic health conditions, including heart failure. Thus, the following nurse-driven clinical question was developed: Among adults with heart failure, how does health education using the teach-back method compared to the traditional didactic method affect self-care? Evidence searches yielded seven studies examining the impact of health education using the teach-back method on self-care in clients with heart failure. Six of the seven analyzed studies concluded that health education interventions using the teach-back method were associated with improved self-care in clients with heart failure. Thus, while not always effective, health education using the teach-back method is an evidence-based practice that can improve self-care in adults with heart failure.
