While much research has been conducted on the software system architecture needed for capturing and managing patient consents and research permissions in health care facilities, limited information is available on the usability of such capture systems. Typically, a general consenting process involves the patients indicating their choices and then signing/initialing to verify these preferences. This study proposes four new ways of capturing these consents/research permissions using Apple iPad…

An investigation of format modifications on the comprehension of information in consent form when presented on mobile devices

A randomized between-subject trial comparing patient comprehension with four different electronic consenting formats of the same consent information presented on an Apple iPad found video with subtitles to convey consent information appears to be the best format among the formats tested for electronic consent presentation.

Informed Consents An investigation of the effect of format modifications on the comprehension of information in consent when presented on mobile devices

Results suggest that video-based systems with subtitles improve consent comprehension, and new interventions for use in the electronic consenting process are proposed and evaluated.

Viewpoint Paper: e-Consent: The Design And Implementation of Consumer Consent Mechanisms in an Electronic Environment

With a well-chosen consent design, it should be possible to balance the specific need for privacy of some of the population against the desire by others to err on the side of clinical safety, and clinicians desire to minimize the burden that an electronic consent mechanism would impose.
