Ethics in Patients' Health Literacy: a scoping review and a critical discussion.

A growing body of literature has acknowledged that a high number of populations with low Health Literacy (HL) is related to poor health outcomes, inequities in healthcare and high economic costs. Those findings have formulated the research questions of this review: (i) what ethical issues arise within the context of patients' HL and (ii) What is the relationship between HL and quality of life? This review followed the guidelines of Joanna Briggs Institute (JBI) and the Preferred Reporting Items for Scoping Reviews (PRISMA-ScR) and it was conducted in five databases: PubMed, CINAHL, MEDLINE, Scopus and Science Direct between June 2022 and December 2023. Out of the 3164 titles retrieved, 285 abstracts were eligible to proceed. Following a thorough examination of the full text of 61 papers, 45 sources were identified that met the inclusion criteria. The data analysis process was guided by the research questions, employing a thematic approach. Four themes were identified: the use of language and patient understanding, human rights, the principlism approach (justice, beneficence, non-maleficence and autonomy) and quality of life. The first theme mainly focused on the relation of HL with the notion of consent forms and national action plans. Human rights in relation to HL were discussed as a minor issue. The bioethical framework by Beauchamp and Childress (Principles of Biomedical Ethics, 6th edn. Oxford University Press, New York, NY, 2009), was addressed by several studies, with a particular focus on justice and the loss of autonomy. Quality of life indicated a positive correlation with HL by most of the authors, while few studies revealed a moderate correlation.
