Video-based Informed Consent in Radiology – Acceptance, Satisfaction, and Effectiveness

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.
