The Influence of Covid-19 on Utilization of Epidural Procedures in Managing Chronic Spinal Pain in the Medicare Population [published online ahead of print, 2022 Dec 28]. Spine (Phila Pa 1976). 2022;10.1097/BRS.0000000000004574. doi:10.1097/BRS.0000000000004574
Study design: A retrospective cohort study of utilization patterns and variables of epidural injections in the fee-for-service (FFS) Medicare population.
Objectives: To update the utilization of epidural injections in managing chronic pain in the FFS Medicare population, from 2000 to 2020, and assess the impact of COVID-19.
Summary of background data: The analysis of the utilization of interventional techniques also showed an annual decrease of 2.5% per 100,000 FFS Medicare enrollees from 2009 to 2018 contrasting to an annual increase of 7.3% from 2000 to 2009. The impact of the COVID-19 pandemic has not been assessed.
Methods: This analysis was performed by utilizing master data from the Centers for Medicare and Medicaid Services (CMS), physician/supplier procedure summary from 2000 to 2020. The analysis was performed by the assessment of utilization patterns using guidance from Strengthening the Reporting of Observational Studies in Epidemiology (STROBE).
Results: Epidural procedures declined at a rate of 19% per 100,000 Medicare enrollees in the FFS Medicare population in the United States from 2019 to 2020, with an annual decline of 3% from 2010 to 2019. From 2000 to 2010, there was an annual increase of 8.3%. This analysis showed a decline in all categories of epidural procedures from 2019 to 2020. The major impact of COVID-19 with closures taking effect from April 1, 2020, through December 31, 2020, will be steeper and rather dramatic, comparing to April 1 to December 31, 2019. However, monthly data from CMS is not available as of now. Overall declines from 2010 to 2019 showed a decrease for cervical and thoracic transforaminal injections with an annual decrease of 5.6%, followed by lumbar interlaminar and caudal epidural injections of 4.9%, followed by 1.8% for lumbar/sacral transforaminal epidurals, and 0.9% for cervical and thoracic interlaminar epidurals.
Conclusion: Declining utilization of epidural injections in all categories was exacerbated to a decrease of 19% from 2019 to 2020 related, in part, to the COVID-19 pandemic. This followed declining patterns of epidural procedures of 3% overall annually from 2010 to 2019.
