Background
Written informed consent (IC) before such interventions as coronary angiography may not ensure that patients understand the rationale, procedural details, and potential risks involved. Barriers include patient anxiety, literacy, and differences in clinicians’ communication skills. Medical graphic narratives (“comics”) may communicate complex health information more clearly.
Objective
To assess whether supplementing standard IC (ICstandard) with a comic (ICcomic) improves patient comprehension, anxiety, and satisfaction.
Methods
From October 2016 to January 2018, a total of 135 consecutive hospitalized patients who were having coronary angiography at Charité – Universitätsmedizin Berlin, Campus Mitte, were screened for enrollment. Of these patients, 121 were randomly assigned to ICstandard (official consent form and conversation with physician) with or without ICcomic (graphic illustrations of central IC aspects based on the official consent form [available at www.annals.org/aim/article/doi/10.7326/G19-0008]); the same physician explained the procedure to all participants. After all participants completed ICstandard, the ICcomic group additionally received the patient comic…
