A radiation therapist's guide to health literacy: A narrative review.

Radiation therapist (RT) communication plays an essential part of patient-centred care in achieving better patient outcomes within radiation oncology. Patients present from a range of social circumstances, education levels and cultural backgrounds, all of which may significantly impact their level of health literacy (HL). Using literature sourced from databases such as EMCare Nursing & Allied Health Database, MEDLINE(R) and APA PsycInfo, this narrative review explores HL definitions, international comparison rates and indications of individual low HL. It also reviews HL assessments as well as exploring enablers and barriers to HL from the RT perspective. Strategies from both the individual or organisational perspective are provided for RTs to begin or continue their HL interest. By educating the radiation therapy profession about health literacy and making small changes in interpersonal interactions, there is the opportunity to impact patients' experiences and outcomes significantly.
