Assessing a narrated white board animation as part of the consent process for intravenous fluorescein angiography: a randomized educational study

Watch this space: a systematic review of the use of video-based media as a patient education tool in ophthalmology

“…Rosenthal et al’s [ 18 ] intervention involved a 6-min videotape on primary open-angle glaucoma showed improved patient knowledge on the condition which was sustained even 6 months after the intervention ( p < 0.01) [ 18 ]. Similarly, Mednick et al [ 19 ] demonstrated better patient understanding of fundus fluorescein angiography with their narrated white board animation ( p < 0.05).…”

“…Furthermore, 7 out of 12 studies (58.3%) measured improvements in patients’ knowledge of a condition or procedure, of which five studies (71.4%) yielded statistically significant results for the intervention. Specifically, this assessed comprehension of cataract surgery [ 15 , 16 ], glaucoma [ 17 , 18 ], intravenous fluorescein angiography process [ 19 ] and parental understanding of retinopathy of prematurity [ 20 ]. More comprehensive data on the outcomes they measured and the scores are outlined in Table 1 .…”

“…However, by contrast Mednick et al [ 19 ] did report that the majority of patients enjoyed the video-based intervention and all were keen to see video-based media become a regular part of the consenting process for fundus fluorescein angiography. Likewise, Pager [ 16 ] found that there was significantly lower likelihood of patients feeling uncomfortable or feeling nervous and uneasy before cataract surgery in a group shown a video on what to expect from cataract surgery compared with the control group shown a video of the anatomy of the lens.…”

A randomized controlled trial comparing video-assisted informed consent with standard consent for Mohs micrographic surgery

“…21,22 In most cases in which videos were used in the consent process, there were improvements in patient satisfaction, 9,11,[13][14][15]20 patient knowledge, or both. 7,8,10,[13][14][15][16][19][20][21]23 Several studies have demonstrated that videos take the same amount of time as standard processes 19 or even save time, 9,12,21 and reduce patient anxiety. 11 Mohs micrographic surgery is a complex multistage procedure, with waiting times in between stages, depending on the extent of the cancer mass before surgical repair of the defect.…”
