Literacy-friendly HF self-care trial
A literacy-sensitive outpatient heart failure education program improved knowledge and self-efficacy but did not clearly cut hospitalizations or quality-of-life scores versus usual care.

127 patients met eligibility criteria and agreed to participate.
127 met eligibility criteria and agreed to participate (Figure ).
61% of control patients and 42% of intervention patients had at least one hospitalization or died (p = 0.13).
61% of patients in the control group had at least one hospitalization or died, and 42% of patients in the intervention group had at least 1 hospitalization or died (p = 0.13).
What they did
Researchers randomized eligible outpatients with clinician-confirmed heart failure to a one-on-one self-management education session with a low-literacy booklet and scale plus structured follow-up, versus a pamphlet and usual care, and followed hospitalization and quality of life for 12 months.
What they found
The intervention group gained more heart-failure knowledge and self-efficacy. Combined hospitalization or death was lower in absolute terms in the intervention arm (42% vs 61%) but not statistically significant; quality of life and cardiac hospitalizations did not differ meaningfully.
The limits
What it doesn't show
It does not prove that literacy-targeted HF education reduces hard clinical events, and the single-clinic sample was too small for definitive event-rate conclusions.

What study design was used?
Common questions
Who was studied?
Outpatients with confirmed heart failure at a university general internal medicine practice, including patients with low literacy.
What did the intervention teach?
Recognizing exacerbation signs, daily weighing, and adjusting diuretic dose, using a below-sixth-grade booklet and teach-back methods.
Did hospitalizations fall significantly?
No; the absolute difference favored intervention but the p-value for hospitalization or death was 0.13.
What clearly improved?
Heart-failure knowledge improved by about 12 percentage points more in the intervention group.
