Scientific title

Evaluation of a risk tailored intervention among low back pain patients in primary care: a cluster randomised controlled trial


Study hypothesis

Primary hypothesis:
The risk tailored intervention is more effective in reducing disability compared to treatment as usual.

Low back pain without specific origin


The intervention consists of two elements:
1. A risk-factor screening and risk tailored educational intervention including information and counselling
2. A telephone/email consulting service concerning back pain related problems independent of risk group assignment

Both elements will be described subsequently:

Risk screening:
All patients fill out a brief risk screening inventory concerning yellow flags that are predictive of chronic back pain. Based on the results patients will be assigned to one of three risk groups (low/intermediate/high).

The tailored interventions are based on the risk factor assignment as follows:
1. Low level risk: patients receive advice on staying active by the general practitioner and will be handed an educational booklet. This booklet aims at reducing erroneous back related beliefs and fosters active health related behaviours. It argues against a biomechanical model by emphasising psychological and social aspects of back problems. Patients receive information regarding local health activities promoting physical exercise, sports, relaxation.
2. Physical risk group: in addition to the physicians' advices and the back book patients in will be offered participation in a guideline based intervention group that consists of two meetings of 120 minutes duration each. The main focus of these manualised meetings will be: education on "back myths" and risk factors, relaxation techniques, and motivation to stay active. Training selected physical exercises is a key element of these meetings. The groups will be conducted by experienced physiotherapists, and exercise therapists. The group size is limited to ten patients.
3. Psychological risk group: patients will receive physicians' advice and the back book. In addition, they will be invited to participate in a psychosocial risk factor group that comprises two additional meetings of 120 minutes duration each. These meetings will be conducted by psychologists with a specialisation in pain treatment. Patients receive a manualised cognitive-behavioural intervention that focusses on pain and strain prone situations as well as on catastrophising, depressive, and fear-avoidant cognitions. The group size is limited to five patients.
4. Combined physical and psychological risk group: patients will receive physicians' advice, the back book and an invitation to particiapte in both intervention groups as described above.

An attendance list will be taken for every course to monitor compliance. Patients receive an illustrated handbook designed specifically for the purpose of this trial with information on all covered topics. All therapeutic sessions will be structured based on a written manual. All participating therapists will have attended a training session of four hours.

Telephone, email counselling:
It is the aim of this counseling offer to answer back pain related questions that usually cannot be handled during a normal consultation. Local study coordinators (usually physiotherapists) will take on enquiries and pass them on to the collaborating MDs, psychologists, and sport scientists, as best suited. No diagnoses will be made during these contacts, neither will there be concrete therapeutic recommendations. A manual will be authored to standardise responses given during the telephone/email counselling.

Primary outcome measures

1. Functional disability as measured with the Hanover Functional Ability Questionnaire
2. Days of sick leave (over a 3-month recall period)

Secondary outcome measures

Patients' characteristics as measured by a questionnaire:
1. Graded chronic pain (Graded Chronic Pain Scale [GCPS])
2. Depression (Patient Health Questionnaire, German version [PHQ-D])
3. Quality of life (PHQ-D, 12-item short form [SF-12])

All measures will be assessed at baseline and, 6 and 12 months after inclusion in the study. Additionally, participation in the counselling groups and telephone/email contacts will be documented.
