Effectiveness of brief patient information materials for promoting correct beliefs about imaging and inevitable consequences of low back pain: A randomised controlled trial.

Objective: To investigate what format for providing patient information (i.e. written summary, infographic or video animation) is most effective for promoting correct beliefs about imaging and inevitable consequences of low back pain (LBP).

Design: Randomised controlled trial.

Setting/patients: One hundred and fifty-nine patients with non-specific LBP were recruited from outpatient physiotherapy clinics.

Intervention: Participants were randomised to receive patient information in one of three formats: video animation, infographic or written summary. Patients were allowed to read or watch the materials for up to 20 min.

Measurements: Outcome were assessed before and immediately after the intervention. The primary outcome was the Back Beliefs Questionnaire. The secondary outcome was beliefs about imaging for LBP assessed by two questions.

Results: All 159 patients completed the study. Our findings revealed no difference between groups for the Back Beliefs Questionnaire. Correct beliefs about imaging were more likely with the infographic than the video animation (Question 1- Odds Ratio [OR] = 3.9, 95% confidence interval [CI]: 1.7, 8.7; Question 2- OR = 6.8, 95%CI: 2.7, 17.2) and more likely with the written summary than the video animation (Question 1- OR = 3.3, 95%CI: 1.5, 7.4; Question 2- OR = 3.7, 95%CI: 1.6, 8.5). No difference between infographic and written summary formats were reported for the questions assessing LBP imaging beliefs.

Conclusion: The three materials were equally effective in improving patient's general beliefs about LBP care. However, the traditional written summary or infographic formats were more effective than the video animation format for improving beliefs about imaging for LBP.
