Educational level and self-care behaviour in patients with heart failure before and after nurse educational...

Self-care is important for heart failure (HF) management and may be influenced by the patient's educational level.

We assessed the relationship of educational level with baseline self-care behaviour and changes one year after a nursing intervention in HF outpatients attending a HF unit.

Three hundred and thirty-five HF patients were studied, with a median age of 67 years (P(25-75) 57-75) and a median HF duration of six months (P(25-75) 1-36). HF aetiology was mainly ischaemic heart disease (53.4%). Median ejection fraction was 30% (P(25-75) 24-37%). The functional class was mainly II (66.3%) and III (25.7%). Educational levels were: very low 17.3%; low 62.1%; medium-high 20.6%. Patients were evaluated at the first visit (baseline) and one year after the educational intervention with the nine-item European Heart Failure Self-care Behaviour Scale.

Median patient scores differed in the baseline (19 (P(25-75) 15-26) vs. 16 (P(25-75) 13-21) vs. 15 (P(25-75) 12.5-15.5)) and the one-year evaluation (15 (P(25-75) 13-17) vs. 13 (P(25-75) 11-15) vs. 12 (P(25-75) 10-14)) for the three educational levels, respectively, with statistically significant differences between levels (p=0.007 to p<0.001) except between low and medium-high education at one year (p=0.057). In the one-year evaluation, self-care behaviour significantly improved in the three educational groups (p<0.001), with a similar, albeit not statistically significant, magnitude of improvement in all groups.

Self-care behaviour at baseline and one year after a nursing intervention was better in patients with a higher education, although the improvement with the intervention was similar irrespective of the educational level.
