Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
JAMA Patient Page on low back pain. 1 page fact sheet delivered by GP or by SMS from GP practice. Content focuses on listing evidence-based treatment options. Freely available resource accessible at: https://jamanetwork.com/journals/jama/fullarticle/2782184

Participants can read the fact sheet at their own time and pace. GPs can open and discuss the fact sheet with their patient during the consult if they wish. Twenty-four hours after their consultation with the GP, HealthShare sends patients an SMS containing a link to the fact sheet on behalf of the GP. To monitor adherence participants will complete a study-specific questionnaire.

Participants can also access the fact sheet via an advertisement on social media (Facebook, Twitter, and Instagram). The advertisement will invite people with experience of back pain to view a fact sheet and complete a short survey.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This study is quasi randomised. Participants are allocated to intervention and control groups via three methods. The first method is based on GP discretion as to which study fact sheet they provide to their patient. The comparison of outcomes for people allocated to fact sheet interventions via this method is therefore non-random. The second allocation method is random. Based on a computerised random number list, a GP software provider will allocate access to either the intervention or control fact sheet, for one month at a time for the duration of the trial. The comparison of outcomes for people allocated to interventions via this method is therefore based on a randomised computer generated sequence.

The third allocation method will be random. Participants via social media advertisement will be allocated to either intervention or control fact sheet randomly.

Statistical methods / analysis
Our primary analysis will compare the PrepDM scores in people exposed to the JAMA fact sheet vs the ACHSQ fact sheet, immediately after they have read the sheet. Assuming a mean difference of 6 points on a 100-point scale (ie 60 points in JAMA fact sheet group, 54 points in ACHSQ group, SD of 26) with 90% power, we require a sample size of 790. To account for anticipated uneven group size we will increase the minimum sample size to 1000.

For the secondary outcomes of management intentions, reassurance, and acceptability, we compare means and proportions where applicable in the whole sample and generate 95% confidence intervals.

Subgroup analysis
We will compare the effects of the sheets on PrepDM scores in people with chronic pain vs acute pain, and in people with higher pain intensity vs lower pain intensity. We will also examine effects on healthcare intentions in people who received the fact sheet through GP-led approach vs patient-led approach, and people who had seen their GP in the past 4 weeks vs those who had not.

Data from patients receiving a fact sheet using random and non-random methods of allocation will be analysed separately in a sensitivity analysis.
