Using a qualitative design, this study aimed to explore the experience of physiotherapists' supporting patient health literacy in clinical practice, gain an understanding of their conceptualisation of health literacy, and make recommendations for improving health literacy support in clinical practice. Convenience sampling via social media was used to recruit eight participants who were all physiotherapists practicing in the United Kingdom. Semi-structured interviews took place on Zoom during the second Covid-19 lockdown. Interviews were audio-recorded, transcribed, coded, and thematically analysed to uncover physiotherapists' views on health literacy, experiences of supporting patients with health literacy and opinions and recommendations for practice. Of the eight participants, five were female and the mean years of clinical experience as a qualified physiotherapist was 5.8. Four main themes were identified: physiotherapists' conceptualisation of health literacy, identification of health literacy and skills required to support patients, training and barriers to providing health literacy-sensitive care and recommendations for improvement. The findings highlighted that physiotherapists identified a patient's health literacy abilities by picking up tacit clues throughout their consultations and they pre-dominantly viewed health literacy as the ability to read, write and communicate effectively. They reported having a limited exposure to health literacy training and recommended raising awareness and education as key to improve practice.
