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

Purpose: 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.Methods: 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 termina-tion). Subjective evaluation of the interventions was provided by the patients after MRI completion. Results: 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 in-formation video received even better evaluations (all p <.027). Conclusion: Additional preparation, especially information, is perceived very positively by patients and at least relaxational preparation may have a positive impact on clinical operations.
