Background

One untested back pain treatment model is to stratify management depending on prognosis (low, medium or high-risk). This 2-arm RCT investigated: (i) overall clinical and cost-effectiveness of stratified primary care (intervention), versus non-stratified current best practice (control); and (ii) whether low-risk patients had non-inferior outcomes, and medium/high-risk groups had superior outcomes.

Background: Last year we presented the STarT Back Tool, which is validated for use in Primary Care. It subgroups patients into 3 categories (high, medium and low risk) on the basis of modifiable risk factors for chronicity. We are now piloting the feasibility of using the tool as part of a new approach to sub-grouping and targeting back pain in primary care.

Methods: The physiotherapy interventions for the 3 subgroups were developed after reviewing the literature, current guidelines, the content of existing targeted treatment programmes, and convening workshops with internationally recognised experts. Both the intervention training modules, and the targeted treatments were piloted. Consecutive back pain consulters were identified using GP electronic Read Codes (weekly downloads) and invited to attend the study’s back pain clinic. Consenting patients completed a baseline questionnaire and were classified by the tool into one of 3 sub-groups.

Results: 60 patients were recruited. 50 patients were allocated to receive treatment according to their subgroup allocation and 10 patients (control group) received a triage physiotherapy assessment (usual care) to decide if they needed further physiotherapy treatment. Primary outcomes include the Roland Morris Disability Questionnaire and the Pain Catastrophising Scale. Three-month follow-up postal questionnaires are currently being administered and outcomes will be presented at the conference. Clinicians involved (GPs, and physiotherapists) will be interviewed to identify the feasibility of this approach.

Conclusions: Once feasibility is established we will take this developmental work forwards into the clinical trial arena to investigate whether this novel “sub-grouping for targeted treatment” approach provides a cost effective way of reducing long-term risk of chronic disability in patients consulting their GP with back pain.
