Abstract

Rationale, aims and objectives; Magnetic resonance imaging (MRI) can be perceived as unpleasant even though the examination is noninvasive. Patients’ knowledge of the MRI procedure is usually scarce, which might enhance patient anxiety at the examination. The aims of this randomized single-blind placebo-controlled trial were to investigate the effects on anxiety and satisfaction with information of a standardized booklet on MRI compared to a placebo booklet delivered to adult patients prior to their first MRI examination. Method; The intervention group (n=95) received a standardized booklet prior to MRI, while the control group (n=102) received a placebo booklet in the same size and lay out but containing general information. The State Trait Anxiety Inventory (STAI) with supplementary questions from the Quality from the Patient’s Perspective questionnaire were used as the patient-reported outcome measures. Results; There was no significant difference in anxiety between the groups, either prior to MRI or during the examination, but those who received the placebo booklet were at higher risk of experiencing high anxiety prior to the MRI examination (odds ratio, 2.64; P=0.029). The intervention group was more satisfied with the information received (P=0.044), and a majority of participants in both groups (≥87%) considered it important to obtain information on the MRI procedure. Conclusion; Standardized written MRI information decreases the risk of experiencing high anxiety levels before MRI and improves patients’ satisfaction with the information. Further research is needed to investigate whether written information prior to MRI is beneficial not only from the patient perspective but if it can also be proven cost-effective.
