Interest of the Return to Primary Care of the "Low Back Pain Booklet" of Health Insurance in the Recovery of Common Acute Low Back Pain

Low back pain is defined as pain or functional discomfort between the twelfth rib and the gluteal fold, which may be median or lateralised. It can radiate up to the thigh but never below the knee. Low back pain is said to be acute if it has been progressing for less than three months. In the acute form, it evolves on a mechanical rhythm, prevents the usual activity and occurs preferably in adults aged 20 to 55 years. 90% of these low back pains are mechanical and common, i.e. characterized by the absence of "red flags ". The red flags refer to a group of characteristic clinical signs that should alert the practitioner to the possibility of an underlying serious spinal pathology and the need for further investigation.

Common low back pain is a public health issue since it is the leading cause of health expenditure in Europe and an economic challenge (900 million euros / year and 19.1% of work stoppages in 2015 compared to 13% in 2005).

In 80% of cases, the general practitioner is in the first line of care in cases of acute low back pain. Indeed, it represents a frequent reason for consultation in general medicine (2nd reason for consultation among general practitioners in 2015).

The doctor must: track down warning signs that call into question the diagnosis of common low back pain (red flags), relieve and reassure the patient. Common low back pain very often heals spontaneously but about 10% of patients will develop chronic low back pain (persistence of pain for more than 3 months). These chronicized patients account for 80% of the total cost of low back pain.

According Paracetamol is often insufficient and it is necessary to switch to level 2 analgesics (tramadol, codeine). NSAIDs are used in short courses.

It is crucial to reassure the patient about the benign nature of the condition and to insist on maintaining activities. Bed rest should never be recommended, let alone prescribed. The usual activities of daily living should be maintained as much as possible within the limits allowed by pain. A work stoppage may be considered if the professional constraints are greater than those of daily life. The return to work has no deleterious effect and must be as early as possible.

It is useful to detect early chronicization factors, especially psychosocial ones. Finally, in order to prevent lumbar disability, patient education, based on the bio-psycho-social model, must be an important part of patient care. The content of the physician's speech strongly influences the patient's beliefs and behaviour. However, if the information can be provided by the therapist, it can also be provided via brochures.

This is why the Health Insurance launched a public information campaign in November 2017 to improve the management of low back therapeutic education, pain, spine sections\], the French Society of Rheumatologyk pain. The French Society of Rheumatology, The French Society of Rheumatology, therapeutic education, pain, spine sections\], the French Society of Rheumatology physical and rehabilitation medicine and the college of general medicine have worked together to publish a "booklet back": I suffer from low back pain: what is it and what to do? whose main objective is to fight against false beliefs concerning inter alia "the benefits of strict rest", to promote physical activity, and to recall the true indications of complementary examinations (radiography, CT, or MRI of the spine) Thus, the back booklet intended for the patient is distributed to general practitioners via the visits of the delegates of the Health Insurance. Nearly 1,600,000 brochures were printed and made available to delegates for distribution to health professionals, with 30 brochures per general practitioner. The brochure is also available for download on ameli.fr in the "insured" and "health professionals" sections (doctors, physiotherapists, care institutions, health centres). In this study, one of the 2 participating centres is the Groupe Hospitalier Paris Saint Joseph (GHPSJ), emergency department. Also, we contacted the health insurance to receive brochures. To our knowledge, there is no other emergency service that has done this. The 2nd service centre participating in the study is the general practitioner consultation centre at the Marie-Thérèse health centre (CMT).
