Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention arm will receive two short videos (<90 seconds each) viewed in succession developed specifically for this study and informed by the content from the TANGO (TAperiNG of Opioids in older adults) brochure (Marcelo et al, 2023). The first video will address opioid risks and benefits, and how to reduce opioid use. The second video will address non-pharmacological pain management strategies such as a healthy lifestyle with regular physical activity and a healthy balanced diet, physiotherapy and pain and stress management, and resources for further information. The content of the videos has been assessed and approved by health practitioners and consumers for credibility, acceptability and readability. The videos are educational only and will explicitly encourage viewers not to change their medication use before consulting with physician. Adherence to the intervention will be monitored via REDCap analytics to ensure participants are watching the full length of the videos.

Once the consent form is completed, participants will be randomly assigned to either the intervention or control group. Participants will then be led to view either the intervention or control video via REDCap. Once the video is viewed, the post-video survey will be shown.

Behaviour
Comparator / control treatment
Participants in the control arm will receive an attention control video on LBP, hip, or knee OA management. This video is freely available on YouTube via this link: https://www.youtube.com/watch?v=jIwn9rC3rOI. The attention control video was selected as it has a similar length to the intervention arm videos combined but does not contain information specific to opioid use. It also provides similar educational information about self-management options albeit for chronic non-cancer pain instead of LBP or hip or knee OA specifically. These include: assessment and ruling out serious conditions, psychosocial management, finding meaningful activities and support networks, sleep and physical activity, and good nutrition.

Strategies to monitor adherence to the attention control video include utilising REDCap analytics to monitor the length of time spent watching the videos. In addition a study-specific questionnaire will ask participants questions around their knowledge of treatment options, medication use and physical activity for managing LBP or hip or knee OA.

Statistical methods / analysis
Descriptive statistics will be used to analyse participant demographics and outcome data providing means and standard deviations (SD) or medians and interquartile ranges (IQR). Two-sample t-tests and Chi2 tests will be utilised to assess baseline differences for continuous and categorical data respectively. Continuous outcomes will be analysed using linear regression models to determine between-group mean differences (MD) and 95% confidence intervals (CI). The effect of the intervention on dichotomous outcomes will be assessed using logistic regression models and presented as odds rations (OR) and 95% CI. These analyses will be adjusted for baseline values including current medication use (chosen a priori) and will be performed as per intention-to-treat.
To explore potential treatment effect heterogeneity, current use of opioids and symptom duration (i.e. less than 3 months or more than or equal to 3 months) will be included in the analyses described above as a treatment effect modifier. Subgroup analyses will be conducted to examine the intervention's effectiveness. Linear and logistic regression models will be used to assess between-group differences in continuous and dichotomous outcomes, respectively, within each subgroup (opioid users vs. non-opioid users; less than 3 months or more than or equal to 3 months symptom duration). All analyses will be conducted using jamovi (version 2.5).

Summary
Brief summary
The aim of this study is to evaluate if a video decision aid (VDA) will reduce patient’s intention to commence or to continue to use opioids amongst patients with low back pain, or hip or knee osteoarthritis (OA) when compared to an attention control video. Participants with low back pain or hip or knee osteoarthritis will be recruited and randomly assigned to watch either an educational video or a control video. Surveys will be used to evaluate the effectiveness of a VDA in reducing the intention to commence or continue to use opioids amongst patients with LBP, or hip or knee OA when compared to an attention control video. It will also assess if the VDA improves the knowledge of management options, attitudes towards opioids, and the likelihood of making an informed choice in this population. We hypothesise that participants with LBP or hip or knee OA who watch a video decision aid will report a significantly lower intention to commence or continue using opioids for pain management compared to those who watch an attention control video.
