Multisite Randomized Trial of a Single-Session Versus Multisession Literacy-Sensitive Self-Care Intervention for Patients With Heart Failure

Background—Self-care training can reduce hospitalization for heart failure (HF), and more intensive intervention may benefit more vulnerable patients, including those with low literacy. Methods and Results—A 1-year, multisite, randomized, controlled comparative effectiveness trial with 605 patients with HF was conducted. Those randomized to a single session received a 40-minute in-person, literacy-sensitive training; the multisession group received the same initial training and then ongoing telephone-based support. The primary outcome was combined incidence of all-cause hospitalization or death; secondary outcomes included HF-related hospitalization and HF-related quality of life, with prespecified stratification by literacy. Overall, the incidence of all-cause hospitalization and death did not differ between intervention groups (incidence rate ratio, 1.01; 95% confidence interval, 0.83–1.22). The effect of multisession training compared with single-session training differed by literacy group: Among those...
