摘要
Objective: To determine if a narrated white board animation (nWBA) video as part of the consent process for intravenous fluorescein angiography (IVFA) improves patient comprehension compared with a standard consent process. Design: Prospective, randomized study. Participants: Patients undergoing an initial IVFA investigation. Methods: Three groups of 26 patients (N = 78) nave to the IVFA procedure were included. Groups 1 and 2 consisted of patients undergoing IVFA for diagnostic purposes. Group 1 received the IVFA information via standard physician patient interaction to obtain standard consent. Group 2 received IVFA information by watching an nWBA explaining the purpose, method, and risks of the diagnostic test to obtain informed consent. Group 3 comprised patients who were not scheduled to undergo IVFA. This group was exposed to both the standard and nWBA consent. All groups completed a 6-question knowledge quiz to assess retained information and a survey to reflect on the consent experience. Results: Participants receiving information via standard physician patient interaction to obtain informed consent had a lower mean knowledge score (4.38 out of 6; 73%) than participants receiving the information to obtain consent via nWBA (5.04 out of 6, 84%; P = 0.023). Of participants receiving both forms of information (group 3) to obtain informed consent, 73% preferred the nWBA to the standard consent process. Conclusions: Participants receiving consent information for an IVFA diagnostic test via nWBA have better knowledge retention regarding the IVFA procedure and preferred this medium compared with participants receiving the standard physician patient interaction for obtaining consent. Incorporation of multimedia into the informed consent process should be explored for other diagnostic tests.
