Health literacy in adult patients with atopic dermatitis: A cross-sectional study

Abstract

BackgroundHealth literacy is defined as the degree to which individuals have the capacity to obtain, process, and understand health information and services needed to make appropriate health decisions. Patients with limited health literacy are less likely to manage chronic diseases appropriately. ObjectiveTo assess the prevalence of limited health literacy in patients with atopic dermatitis (AD), and its association with other patient-reported outcomes. MethodsA cross-sectional questionnaire-based study was conducted at a tertiary referral centre for AD. Patients diagnosed with AD by a dermatologist between 2019 and 2021 were identified from medical records. Perception-based health literacy was assessed by the European Health Literacy Survey Questionnaire 16 (HLS-EU-Q16) and performance-based health literacy by the Newest Vital Sign (NVS). Patients completed the Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), and Atopic Dermatitis Control Tool (ADCT) to measure AD severity, quality of life and AD disease control, respectively. ResultsIn total, 322 patients were included (response rate 48.3%). Based on the HLS-EU-Q16, 32.4% had limited health literacy (8.4% inadequate and 24.0% problematic) which was associated with impaired quality of life. According to the NVS, 20.3% had inadequate health literacy which was associated with older age. ConclusionUp to one-third of the patients with AD showed signs of limited health literacy, which was associated with impaired health related quality of life and older age. Further research should evaluate the influence of inadequate health literacy on health outcomes and focus on strategies to improve organizational health literacy to eventually enhance patient-centered care.
