Plain English Summary
Background and study aims
"Sciatica" describes patients who have back-related leg pain, often felt below the knee, or other leg symptoms such as pins and needles or muscle weakness. It has a significant impact on patients’ lives, which can lead to problems doing everyday activities, time off work, and financial burdens for the patient and their family and health and social services. Whilst many patients have mild problems, up to 30% of sufferers have pain for a year or more and incur considerable costs. In primary care (for example, in a GP setting) our research shows that up to 70% of patients with back-related leg pain either have sciatica or are suspected of suffering from the condition. Patients with sciatica tend to be managed with a 'wait and-see' approach, with some eventually being referred to other healthcare professionals. This could include physiotherapists for help with pain and function, or spinal specialists including pain specialists and orthopaedic surgeons. Current treatments range widely from information and advice, medications, exercise and manual therapy, and more invasive treatments such as spinal injections and surgery. One particular problem for patients is the current delay in treatment. The wide variation in the management of patients throughout the UK means that some patients are offered unnecessary treatments whilst others have to wait a long time to get treatments that will work. The recently published NHS Spinal Taskforce (January 2013) made some recommendations based largely on the opinion of experts rather than research evidence, highlighting the urgent need for good quality trial evidence about treatments for sciatica. Given that the responsibility for early treatment decisions for patients with sciatica is in primary care, high quality research in this setting is particularly needed. Here, we want to improve primary care management of patients with sciatica through a new approach called stratified care. Stratified care is a model of care with two components; clearer identification and subgrouping of patients with different characteristics and ii) matching of patient subgroups to different treatments. lt includes early identification of patients who are most likely to benefit from referral to spinal specialists. Our stratified care approach combines systematic information about individual patients' likelihood of recovery (prognostic information) with information from their clinical history and physical examination (clinical indicators of the severity of sciatica) in order to ensure that the right patient gets the right treatment at the right time. Using a systematic, step-by-step procedure that combines information about each patient's likelihood of a poor outcome (for example, not respond well to treatment) and the presence of important clinical indicators, patients with sciatica will be grouped into one of three subgroups (referred to as low, medium and high risk) and matched to appropriate and timely treatments. Patients will be grouped into those likely to get better who can be given good advice and self-help support in up to two treatment visits, those with more troublesome problems who should be referred for a course of physiotherapy treatments and those with more significantly troublesome problems who need to be seen early by spinal specialists for assessment and treatment.
Who can participate?
Adults aged at least 18, who are going to their GP with sciatica or suspected sciatica. They must also have a mobile phone that can receive and send SMS texts or have access to a land line telephone.
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 receive the usual care. Those in group 2 receive stratified care. Participants in group 2 are placed into a subgroup according to predicted outcome. Those placed in the low risk subgroup are given a brief treatment package by physiotherapists in up to two treatment visits. Those in the medium risk subgroup receive an average of 6 treatment sessions over an average of 3 months tailored to their needs. Those in the high risk subgroup are fast tracked to spinal specialists for assessment of their suitability for other treatments such as spinal injections or surgery. All participants report on their symptoms via a weekly SMS text message for the first 4 months and then monthly from months 4 to 12 or until the participant reports on two consecutive months that they have recovered.
What are the possible benefits and risks of participating?
There are no direct risks of taking part in the trial. The care participants receive from their doctor will not be affected. This is a randomised trial therefore participants cannot choose which treatment (care) pathway they receive. This helps us to make a fairer comparison between the two different types of care provided in the study. However, the treatments in the care pathways we are testing in this study are currently used in the care of sciatica.

1. Usual non-stratified care. Participants randomised to this arm will receive usual, non-stratified care. They will be seen by a physiotherapist for one off assessment and treatment including education and advice, with onwards referral to further treatment if necessary.
2. Stratified care. Participants randomised to this arm will receive treatment according to their risk subgroup (referred as low, medium, high):
2.1. Low risk subgroup: participants will receive a brief treatment package delivered by trial physiotherapists, in up to two treatment visits.
2.2. Medium risk subgroup: participants will receive a course of physiotherapy treatment delivered in an average number of six sessions over an average of three months and tailored to their individual needs.
2.3. High risk subgroup: participants will be fast-tracked to spinal specialists for assessment and opinion about suitability for other treatments, such as spinal injections or surgery
Primary outcome measures
Time to resolution of sciatica symptoms measured on a 6-point ordered categorical scale. Data will be collected by weekly SMS text messages for the first 4 months, then from months 4 to 12 the SMS data collection will change to monthly, or until patients report on two consecutive occasions that they have recovered.
Secondary outcome measures
1. Leg and back usual pain severity is measured using pain intensity of back and leg pain at baseline, 4 and 12 months
2. Disability is measured using Roland Morris Disability Questionnaire at baseline, 4 and 12 months
3. Overall impact of sciatica symptoms is measured using Sciatica Bothersomeness Index at baseline, 4 and 12 months
4. Sleep disturbance is measured using Jenkins sleep questionnaire at baseline, 4 and 12 months
5. Fear of movement is measured using Tampa Scale of Kinesiophobia at baseline, 4 and 12 months
