Use of Video in End of Life Decision-Making: a Concern

Videos have come to be regarded by many as a valuable aid in helping patients make decisions about their care when such videos supplement a conversation with a physician that explains possible treatment options. A number of research studies (here, here and here) suggest that such use of videos can lead to more informed patients and, for patients approaching the end of life, a greater likelihood of patients opting for comfort care rather than life prolonging treatments.
I would like to express one source of unease with the use of video in this context and identify a possible weakness in the associated empirical studies.
Several studies feature a patient factual assessment, a set of multiple choice and true/false questions about relevant medical care. Those who watch the videos and receive a verbal explanation of treatment options generally score better on this assessment than the control group, who receive only the ordinary verbal explanation. The authors of the studies conclude from the assessment scores that the video group are more informed about the relevant treatment options, and naturally infer that this group’s greater preference for comfort care over life prolonging care is to be accounted for in terms of their being more informed than the control group. This offers a positive outlook for the place of video in supplementing the physician’s verbal explanation as a means for patient education and empowerment:

When faced with the possibility of their cancer progressing, participants with malignant glioma who viewed a video of the various goals-of-care options in addition to listening to a verbal description were more likely to prefer comfort measures and avoid CPR, were more knowledgeable regarding the subject matter, and were more certain of their decision when compared to patients only hearing a verbal narrative.
