Background And ObjectiveThere is a substantial gap between evidence and clinical care for low back pain (LBP) worldwide despite recommendations of best practice specified in clinical practice guidelines. The aim of this systematic review was to identify disparities associated with race or ethnicity in the use of lumbar imaging, opioid analgesics, and spinal surgery in people with LBP.Databases And Data TreatmentWe included observational studies which compared the use of lumbar imaging, opioid analgesics, and spinal surgery for the management of non-serious LBP between people from different racial/ethnic populations. We searched in MEDLINE, EMBASE and CINAHL from January 2000 to June 2021. Risk of bias of included studies was appraised in six domains. For each type of care, we pooled data stratified by race and ethnicity using random effects models.ResultsWe identified 13 eligible studies; all conducted in the United States. Hispanic/Latino (OR 0.69, 95%CI 0.49-0.96) and Black/African American (OR 0.59, 95%CI 0.46-0.75) people with LBP were less likely to be prescribed opioid analgesics than White people. Black/African Americans were less likely to undergo or be recommended spinal surgery for LBP (OR 0.47, 95%CI 0.33-0.67) than White people. There was a lack of high certainty evidence on racial/ethnic disparities in the use of lumbar imaging.ConclusionThis review reveals lower rate of the use of guideline-discordant care, especially opioid prescription and spinal surgery, in racial/ethnic minority populations with LBP in the United States. Future studies in other countries evaluating care equity for LBP are warranted. PROSPERO Registration ID: CRD42021260668.SignificanceThis systematic review and meta-analysis revealed that people with low back pain from the minority racial/ethnic backgrounds were less likely to be prescribed opioid analgesics and undergo spinal surgery than the majority counterparts. Strategic interventions to improve the access to, and the value of, clinical care for minority populations with low back pain are warranted.© 2022 European Pain Federation - EFIC ®.
