Scientific title

Clinical course and prognostic indicators in patients presenting with back and leg pain in primary care: 3, 4 and 5 year prospective study (ATLAS study cohort)

Acronym

ATLAS follow-up study

Study hypothesis

Patients with back pain may or may not experience pain which spreads to their legs. Previous research has found that patients who have back and leg pain suffer more severe pain and disability, take longer to recover, and lose more time off work than those with back pain alone. However, it is not known if this is because of the leg pain or some other related factors. One type of leg pain, called ‘Nerve Root Pain’, often spreads below the knee and means there is a problem with the nerves in the spine. Doctors think it is important to distinguish between patients who have back pain alone, those with back and leg pain, and those with back pain and nerve root pain. This is so that these groups can be assessed and treated appropriately. We are currently conducting an observational study (ATLAS cohort) with the aim to describe over one year the clinical course, characteristics and factors that predict outcome in patients consulting in primary care with back and leg pain including sciatica. Our aim is to conduct longer term follow-ups (at 3, 4 and 5 years) of this established cohort in order to describe over a longer time frame the clinical course, characteristics, factors that predict outcome and health care utilisation over time, including direct and indirect health care costs. We will also investigate similarities and/or differences of those factors at the different time points and characterise better what predicts short-term and long-term outcomes. This knowledge will inform better targeting of treatment to improve outcomes in patients with back and leg pain, which will be tested in future trials.

Intervention

The ATLAS study looked at how people who visit their GP with back and leg pain do over time. This follow-up study aims to follow the same group of people at 3, 4 and 5 years after their initial participation in the ATLAS study to understand why some people take longer periods of time to recover than others. This information will be used to develop ways to improve the care of people with back and leg pain.

Our aim is to conduct longer term follow-ups (at 3, 4 and 5 years) of the established ATLAS cohort in order to describe over a longer timeframe the clinical course, characteristics, prognostic indicators and health care utilisation over time, including direct and indirect health care costs. We will also investigate similarities and/or differences of prognostic indicators at the different time points.

At baseline ATLAS (REC Reference: 10/H1207/82) participants attended an initial assessment clinic visit followed by treatment as appropriate, and were then followed up by questionnaire for 12 months. In this proposed study of longer term follow-up of the ATLAS cohort, ATLAS participants (with the exception of those who withdrew from the study or declined further contact for research purposes at their 12-month questionnaire) will be approached. Potential participants will be sent a letter introducing the new longer term follow-up study 2 weeks before the third anniversary of their baseline ATLAS assessment visit, followed by further information and the study questionnaire 2 weeks later. Participants who respond to this questionnaire will then be sent two further questionnaires at 4 and 5 years, respectively. Participants will also be asked to give permission for medical record review to capture GP visits and medication for the same problem and secondary care/hospital visits (inpatient and outpatient) in order to describe health care used over time by this cohort.

Primary outcome measures

Improvement in the RMDQ (Roland and Morris Disability Questionnaire using the leg pain version): defined as a change of at least 30% improvement in an individual’s RMDQ score (Jordan et al., 2006). This will be measured at 3, 4 and 5 years.
