Heart failure (HF) remains the most common diagnosis of hospital admission among U.S. adults. Although diagnosis and treatment have improved, mortality rates have not changed, and mortality risk remains high after hospitalization. The current researchers examined how limited health literacy is associated with mortality risk in adults with recent hospitalization due to decompensated HF. Researchers conducted a systematic literature search, selecting three cohort and three intervention studies. The fixed-effect model was used. From the three cohort studies, 2,858 study participants were analyzed. Among participants, limited health literacy was associated with higher all-cause mortality (pooled odds ratio = 2.95; 95% confidence interval [2.34, 3.72]; p < 0.01; I 2 = 47.38%). However, none of the intervention studies showed an association between limited health literacy and cardiac (or all-cause) mortality. Future research should focus on the efficiency and safety of telehealth-based medicine in patients with HF, particularly those with limited health literacy.
