Effects of video-based patient preparation for MRI on clinical processes and patient experience

To determine whether video-based informational or relaxational preparation reduces the number of unexpected patient-related events and scan duration more efficiently, and to assess how patients evaluate the interventions.

We randomized 142 adult patients (mean age: 48 ± 16 years) to three groups. The control group (n = 48, 33.8 %) received standard care. The intervention groups watched an informational (n = 50, 35.2 %) or relaxational (n = 44, 31.0 %) video while awaiting their MRI examination. We recorded scan duration, number of motion artifacts/sequence repetitions, and patient-related incidents (e.g., interruptions, premature termination). Subjective evaluation of the interventions was provided by the patients after MRI completion.

Mean scan duration for the control, relaxation, and information group was 39.38 ± 16.62 min, 32.59 ± 11.67 min, and 34.54 ± 11.91 min. Compared to the control group, scan duration was significantly shorter in the relaxation, but not in the information group (relaxation vs control: p =.019; information vs control: p =.082). The information and relaxation group did not differ significantly (p =.704). In 35 (24.6 %) patients, one or more sequences were repeated; incidents occurred in six (4.2 %) patients. Neither the frequency of repeated sequences nor incidents differed between the groups (all p >.239). Patients evaluated both videos very positively; the information video received even better evaluations (all p <.027).

Additional preparation, especially information, is perceived very positively by patients and at least relaxational preparation may have a positive impact on clinical operations.
