Health Literacy, its Effect on Emergency Department Utilization, and a Smartphone-based Intervention

Abstract

Health literacy is not only the ability to read, but also the ability of an individual to obtain, process, and understand the basic health information needed to make appropriate health decisions. Over time the concept of health literacy has evolved from considering it a risk factor to be managed to considering it an asset which can be continually built upon. With this in mind health professionals should continue to communicate in simple language, but should also provide their patients with high-quality educational materials and aid them in making the best choices about their health. One way to do this could be with the use of symptom-checking and decision-aiding smartphone apps. In this study, the primary caretakers of children aged 30 months and younger with publicly funded health insurance will be randomized to receive a pediatric symptom-checking smartphone app or a developmental milestone smartphone app. Caretaker health literacy will be measured, and data will be collected on emergency department and primary care office sick visits. It is hypothesized that the use of the pediatric symptom-checking smartphone app will decrease non-urgent visits to the pediatric emergency department.
