Participants were selected if they were diagnosed with CLBP (N = 2663) or OA (N = 139) of more than 3 months duration and of pain intensity ≥ 5 on the Numeric Rating Scale (0– 10) and completed baseline questionnaires.Results: Less than 5% of persons were hospitalized in the 6 months before their first visit at the pain clinic, and 11.9% and 18.9% of persons with OA and CLBP, respectively, had a pain-related emergency room (ER) visit. Less than 1/5 and more than 1/4 of persons with OA and CLBP were receiving disability benefits, respectively. Persons with CLBP who had visited the ER, those on disability and those receiving disability benefits, reported higher levels of pain severity, interference, and lower levels of mQoL (and pQoL for those on disability or receiving benefits) compared to those who did not consult the ER, those not on disability or not receiving disability benefits, respectively (all p < 0.05). For OA, disability status was the only variable associated with pain interference and QoL (all p < 0.05).Conclusion: Pain severity, pain interference and mQoL were associated with health-care utilization and disability status in persons with CLBP. These results were globally not found among persons with OA, which might be due to smaller sample size or unique characteristics of this population.Keywords: osteoarthritis, Quebec Pain Registry, healthcare utilization, back pain, quality of life |
