Influence of Health Literacy on HRQoL in Patients After PCI

Abstract

Among increased concerns about the adverse health outcomes of inadequate health literacy, it still remains unclear how health literacy influences health-related quality of life (HRQoL) of patients who have undergone percutaneous coronary intervention (PCI). Therefore, the aim of the study was to examine the impact of health literacy on HRQoL in PCI patients at 6 months after discharge. This study used a self-reported questionnaire to assess health literacy, medication knowledge, and HRQoL in 238 patients. In hierarchical linear regression, health literacy was the strongest predictor of HRQoL after adjusting confounding factors (β = .23, p = .003). In addition, this study showed that medication knowledge acted as a partial mediator between health literacy and HRQoL. In conclusion, adequate health literacy is a contributing factor to better HRQoL in patients after PCI, and health literacy can lead to improved HRQoL in PCI patients through the acquisition of sufficient medication knowledge.

Health-Related Quality of Life in Older Adults: Its Association with Health Literacy, Self-Efficacy, Social Support, and Health-Promoting Behavior

“…The present findings are consistent with those of previous studies, suggesting that HL had a positive influence on HRQOL [30,42]. However, inadequate reading comprehension and numeracy skills can inhibit a patient's ability to attend appointment schedules with their clinicians and follow the prescription instructions correctly [43].…”

Health Literacy but Not Frailty Predict Self-Care Behaviors in Patients with Heart Failure

“…In this study, the mean health literacy score was 8.89, which was below the 11 to 12 score that indicated adequate health literacy [ 25 ]. It was also lower than the mean score of Korean patients undergoing percutaneous coronary intervention (10.72) [ 31 ] and the mean score of patients with diabetes (10.61) [ 32 ]. Moreover, in a previous study on patients with hypertension, the prevalence of low health literacy (marginal and inadequate levels) was 76.9% [ 26 ], while in this study on patients with heart failure, the prevalence was 54.8%.…”
