Low back pain is a public health problem with major individual and socio-economic repercussions. In primary care, strong disparities are observed in the management of low back pain patients. While general practitioners (GPs) and physiotherapists appear as two essential first-line caregivers, collaboration between these professionals remains underdeveloped, most often characterized by a lack of consultation or coordination. Systematic increased interprofessional collaboration is likely to improve the results of the care pathway, by optimizing the existing care offer.
