Is a Picture Worth a Thousand Words? A Scoping Review of the Impact of Visual Aids on Patients Undergoing Surgery

OBJECTIVE: While graphics are commonly used by clinicians to communicate information to patients, the impact of using visual media on surgical patients is not understood. This review seeks to understand the current landscape of research analyzing impact of using visual aids to communicate with patients undergoing surgery, as well as gaps in the present literature. DESIGN: A comprehensive literature search was performed across 4 databases. Search terms included: visual aids, diagrams, graphics, surgery, patient education, informed consent, and decision making. Inclusion criteria were (i) full-text, peer-reviewed articles in English; (ii) evaluation of a nonelectronic visual aid(s); and (iii) surgical patient population. RESULTS: There were 1402 articles identified; 21 met study criteria. Fifteen were randomized control trials and 6 were prospective cohort studies. Visual media assessed comprised of diagrams as informed consent adjuncts (n = 6), graphics for shared decision-making conversations (n = 3), other preoperative educational graphics (n = 8), and postoperative educational materials (n = 4). There was statistically significant improvement in patient comprehension, with an increase in objective knowledge recall (7.8%-29.6%) using illustrated educational materials (n = 10 of 15). Other studies noted increased satisfaction (n = 4 of 6), improvement in shared decision-making (n = 2 of 4), and reduction in patient anxiety (n = 3 of 6). For behavioral outcomes, visual aids improved postoperative medication compliance (n = 2) and lowered postoperative analgesia requirements (n = 2). CONCLUSIONS: The use of visual aids to enhance the surgical patient experience is promising in improving knowledge retention, satisfaction, and reducing anxiety. Future studies ought to consider visual aid format, and readability, as well as patient language, race, and healthcare literacy. ( J Surg Ed 81:1276-1292.- 1292.
