Abstract
Purpose
Before any medical procedure, including computed tomography (CT), it is crucial to
ensure patients are fully informed about the risks and alternative options. Video-based
informed consent offers an increased transfer of information in less time.
Materials and Methods
In a monocentric, prospective, questionnaire-based study, video-based informed consent,
which included a digital medical history form, was compared to the traditional paper-based
consent form. Two groups (doctors and patients) were divided into a control group
(traditional informed consent) and one study group (video-based informed consent).
Participants rated their satisfaction and acceptance on a scale of 1 to 6 (1: very
good). Additionally, patients’ understanding of the information provided was evaluated,
and the duration of informed consents process was measured.
Results
A total of 205 patients in the control group and 150 in the study group were surveyed.
Satisfaction ratings of “very good” or “good” were similar for both methods (91% control
group, 94% study group). The patients’ study group showed a higher recall of the information
provided in all six areas, e.g. radiation exposure (73% control group; 86% study group).
Among the doctors, 20 from the control group and 11 from the study group were interviewed.
Satisfaction was significantly higher in the study group (30% control group, 72% study
group).
The duration of the traditional informed consent process averaged 270.2 seconds, compared
to 228.7 seconds for the video-based informed consent.
Conclusion
Satisfaction with video-based information is high among both patients and doctors.
Patients retain the content more effectively with video-based informed consent, which
also saves time.
Key Points
-
Video-based informed consent shows high levels of satisfaction and acceptance among
patients and doctors.
-
After a video-based informed consent consultation, patients were better able to remember
the information provided.
-
Compared to conventional informed consent consultations, video-based consultations
save time.
