Care trajectories for musculoskeletal disorders following a new episode of low back pain.

This study explored diverse care trajectories (CTs) for low back pain (LBP) and other musculoskeletal disorders (MSDs), over a 5-year period following a first episode of LBP. Based on Quebec's administrative health data from 2007 to 2011, this longitudinal cohort study involved 12,608 adults seeking health care for LBP. Using a new multidimensional state sequence analysis, we identified 6 distinct types of CTs. The most prevalent types 1, 2, and 3 (comprising 79.2%, 18.0%, and 21.7% of the cohort, respectively) exhibit rapid recovery and similar patterns of healthcare use over 5 years but differing in initial diagnoses: nonspecific LBP in type 1, trauma-related LBP in type 2 (mostly younger men and highest initial emergency consultation), and specific LBP in type 3. Types 4 to 6, representing smaller groups, show high healthcare utilization with comparable mixed LBP diagnoses at entry but distinctive subsequent care use patterns. Patients in types 4 and 6 (mainly older age groups and women) sought care for other MSDs from general practitioners or specialists, while middle-aged patients in type 5 experienced persistent nonspecific LBP with frequent general practitioner consultations over 5 years. The CTs typology revealed several key areas for improvement in nonpharmacological interventions, including the need to address possible inappropriate medical imaging and invasive interventions for older women with MSDs and the lack of ambulatory care access for younger patients with trauma-related LBP. Finally, results clearly highlighted poor access to rehabilitation physicians and rehabilitation services for all patients suffering from LBP and MSDs.
