Abstract

In light of the number of spinal disorders and the significant costs associated with them, the IRSST formed a working group to characterize the frequency and distribution of spinal disorders among Québec workers, propose a classification system for spinal disorder pathology and interventions, establish intervention strategies, define diagnostic and health care quality criteria, recommend techniques by which health care could be evaluated, and identify research priorities in this field. Over 3 000 medical files of workers having received compensation for back problems were studied by the group, and over 700 scientific articles reviewed. The study demonstrated that 7.4% of Québec workers receiving compensation for back disorders become chronic cases, and account for over 70% of work absences and medical and compensation expenses in this category. Classification systems based on therapeutic goals were developed for spinal column pathologies and various types of interventions. The report also provides patient follow-up algorithms and frameworks for the evaluation of clinical and diagnostic procedures. The report is useful to both doctors and others responsible for occupational health and safety.
