Effective medical communication is critical for patient consent, adherence to treatment, and improved health outcomes. Visual aids, such as infographics, diagrams, and charts, have proven invaluable for enhancing comprehension, particularly of complex medical concepts like risks and numerical data. Historically, medical visualisations have played a vital role, from Renaissance anatomical atlases to modern-day graphical abstracts and patient-centred infographics. Innovations in visual communication underscore their transformative power in healthcare. Despite their long- standing utility, visual aids remain underused in patient information, which often suffers from overly complex language and poor design. The integration of visuals into clinical trial reporting, informed consent forms, and treatment plans has gained momentum, supported by guidelines advocating for patient-focused communication. Recent studies confirm that well-designed visuals improve comprehension, engagement, and equity in healthcare communication. As user-friendly tools become more accessible, visual aids will become integral in advancing patient-centred, inclusive healthcare practices.
