Heart Failure (HF) treatment may be improved by good knowledge of the disease (Health Literacy) that, despite the well-established role on improving self-care, preventing complications and avoiding worse outcomes, has little evidence on affecting QoL of HF patients. Therefore, the objective of the present study was to evaluate the impact of Health Literacy on QoL in hospitalized HF patients.
A cross-sectional exploratory study was conducted with HF patients hospitalized at a public cardiological hospital. Health Literacy was assessed using the "Questionnaire about Heart Failure Patients' Knowledge of Disease" and QoL using the "Minnesota Living with Heart Failure Questionnaire" (MLHFQ). The association between Health Literacy and QoL was assessed by linear regression (P<0.05).
50 patients were included in the study; the mean Health Literacy score was 34.2 ± 15.1 (the majority presenting acceptable or better knowledge). The mean MLHFQ score was 73.5 ± 19.8. The one-year hospital readmission rate (β=+3.8; P=0.009) and the patients' Health Literacy score (β=-0.4; P=0.024) or good knowledge category (β=-20.2; P=0.016) were independently associated with QoL.
While the readmission rate was inversely associated with QoL, the better the HF knowledge the better QoL in hospitalized HF patients.
对心力衰竭（HF）疾病的充分了解（健康素养）可能会改善HF的治疗效果。尽管健康素养在改善自我护理、预防并发症和避免更差结局方面的作用已得到充分确立，但关于其对HF患者生活质量（QoL）影响的证据却很少。因此，本研究的目的是评估健康素养对住院HF患者QoL的影响。
对一家公立心脏病医院收治的HF患者进行了一项横断面探索性研究。使用“心力衰竭患者疾病知识问卷”评估健康素养，使用“明尼苏达心力衰竭生活问卷”（MLHFQ）评估QoL。通过线性回归评估健康素养与QoL之间的关联（P<0.05）。
50名患者纳入研究；健康素养平均得分为34.2±15.1（大多数患者知识水平可接受或更高）。MLHFQ平均得分为73.5±19.8。一年住院再入院率（β=+3.8；P=0.009）以及患者的健康素养得分（β=-0.4；P=0.024）或良好知识类别（β=-20.2；P=0.016）与QoL独立相关。
虽然再入院率与QoL呈负相关，但住院HF患者对HF的知识掌握得越好，QoL越高。
