Beyond Access Block: Understanding the Role of Health Literacy and Self-Efficacy in Low-Acuity Emergency Department...

Background: Health literacy, self-efficacy, and patient satisfaction are factors associated with healthcare utilization. The relationships among these factors and their combined impact on patients' self-rated health have historically been studied in chronic disease populations. This study assessed low-acuity emergency department (ED) patients' ratings of these factors, the relationships among these factors, and their effect on re-presentation rates to the ED. Methods: In this single-arm cohort survey, patients provided demographic data, completed health literacy and self-efficacy assessments prior to being seen by a physician, and completed a discharge perceptions questionnaire that included a global satisfaction question at the time of departure. Three months later, patients answered a telephone survey to measure post-ED visit health outcomes. Results: Health literacy (r=0.114, P=0.023) and self-efficacy (r=0.469, P<0.001) were both independently and positively associated with self-rated health. Neither factor was associated with patient satisfaction. Self-rated health was negatively associated with return ED visits (r=-0.137, P=0.011). Conclusion: Existing research shows that health literacy has a linear association with self-efficacy and self-rated health. The results of this study suggest that in the context of low-acuity ED patients, health literacy and self-efficacy affect patients' understanding of their health status (self-rated health) but do not lead to better utilization of healthcare resources. Improvement of health literacy and self-efficacy, specifically to increase self-rated health, may provide a future avenue of intervention to reduce low-acuity ED patient re-presentation.
