Healthcare Utilisation in Danish Primary Care Among Patients With Low Back or Neck/Thoracic Spine Pain Before and After Assessment in Secondary Care.

Objectives: To describe characteristics and primary healthcare utilisation in Danish patients with low back pain (LBP) or neck/thoracic spine pain (NTP) 8 years before and 2 years after assessment in secondary care.

Methods: In this cohort study, we included patients aged ≥ 18 who were assessed at an outpatient spine clinic from 2013 to 2021 and linked self-reported information with national registry data. We calculated the prevalence of all-cause healthcare utilisation in primary care. Then, we determined changes in the number of consultations from before to after assessment in secondary care using generalised estimating equations.

Results: We included 56,949 LBP patients and 18,926 NTP patients. The baseline characteristics were similar overall. For both LBP and NTP, all-cause healthcare utilisation increased slightly over time, with a substantial increase in the quarter before the secondary care assessment and a decrease after. Before the assessment, almost all patients consulted general practitioners (95%), while some consulted physiotherapists or chiropractors (60%). Overall, consultations decreased by 19% and 17% for patients with LBP and NTP from 12 to 1 month before to 1-12 months after the assessment. In contrast, 13-24 months after assessment, we found a slight increase in consultations in both groups compared to the same period before.

Conclusions: Patients with LBP and NTP were similar and used similar primary healthcare, which slightly increased over the 10 years. As physiotherapists and chiropractors are first-line providers of guideline-recommended spine pain treatment, the finding that 40% did not consult these professions the year before the secondary care assessment indicates that not all patients receive recommended care before referral.
