Burden of disease of chronic pain in Colombia

Objectives: To assess the burden of disease of chronic pain in Colombia. Methods: We estimated disability adjusted life years (DALYs) attributable to chronic pain using Global Burden of Disease (GBD) method. We identified diagnostic codes related to chronic pain considering lumbar pain, osteoarthritis, post-herpetic neuralgia, diabetic neuropathy, cancer-related pain, and others. We estimated the prevalent cases by sex and age-group using local administrative databases and literature. We assumed that pain would not cause premature death, so we only estimated years lived with disability using disability weights obtained from the GBD. We used a prevalence-based approach, without discounting or age-group adjustment. We calculated total DALYs and DALYs/100,000 inhabitants. Results: We estimated a total of 5,545,019 patients with chronic pain. We calculated 491,626 DALYs or 976 DALYs/100,000 inhabitants attributable to chronic pain. Low back pain, osteoarthritis, and cancer-related pain were the most important groups. Conclusions: This study estimates that chronic pain contributes a significant quantity of DALYs, especially related to low back pain, osteoarthritis, and cancer-related pain. Chronic pain should be considered in the public health agenda.
