ABSTRACT
INTRODUCTION: The COVID-19 pandemic resulted in major disruptions in all aspects of human life including a decline of medical services utilized during 2020. An analysis of the impact of COVID-19 pandemic showed an 18.7% reduction in utilization patterns of interventional techniques in managing chronic pain in the Medicare population from 2019 to 2020. However, specific changes in utilization patterns of facet joint interventions have not been studied. Thus, we sought to assess the utilization patterns including an update of facet joint interventions from 2018 to 2020, with analysis of the impact of COVID-19 pandemic in managing chronic spinal pain utilizing facet joint interventions in the fee-for-service Medicare population of the United States. METHODS: The present investigation was designed to assess utilization patterns and variables of facet joint interventions, in managing chronic spinal pain from 2010 to 2020 in the fee-for-service (FFS) Medicare population in the United States (US), and how the COVID-19 pandemic impacted these utilization patterns. Data for the analysis were obtained from the master database from the Centers for Medicare & Medicaid Services (CMS) physician/supplier procedure summary from 2000 to 2020. RESULTS: Results of this analysis showed significant impact of COVID-19 with overall decrease of 18.5% of all facet joint interventions per 100,000 Medicare population compared to 20.2 and 20.5% decrease for lumbar and cervical facet joint injections, 15 and 13.1% decrease per 100,000 Medicare population of lumbosacral and cervicothoracic facet joint neurolysis procedures. The results are significant in that comparative analysis from 2000 to 2010 and 2010 to 2019 showing an annual increase of 14.4 vs. 2.2%, illustrating a decelerating pattern. There were also significant growth patterns noted with decreases in facet joint injections and nerve blocks compared to facet joint neurolytic procedures. CONCLUSIONS: This analysis shows a significant effect of COVID-19 producing an overall decrease in utilization of facet joint interventions relative to pre-COVID data. Further, the analysis demonstrates continued deceleration of utilization patterns of facet joint interventions compared to the periods of 2000-2010 and 2010-2019.
ABSTRACT
BACKGROUND: Multiple publications have shown the significant impact of the COVID-19 pandemic on US healthcare and increasing costs over the recent years in managing low back and neck pain as well as other musculoskeletal disorders. The COVID-19 pandemic has affected many modalities of treatments, including those related to chronic pain management, including both interventional techniques and opioids. While there have not been assessments of utilization of interventional techniques specific to the ongoing COVID-19 pandemic, previous analysis published with data from 2000 to 2018 demonstrated a decline in utilization of interventional techniques from 2009 to 2018 of 6.7%, with an annual decline of 0.8% per 100,000 fee-for-service (FFS) in the Medicare population. During that same time, the Medicare population has grown by 3% annually. OBJECTIVES: The objectives of this analysis include an evaluation of the impact of the COVID-19 pandemic, as well as an updated assessment of the utilization of interventional techniques in managing chronic pain in the Medicare population from 2010 to 2019, 2010 to 2020, and 2019 to 2020 in the FFS Medicare population of the United States. STUDY DESIGN: Utilization patterns and variables of interventional techniques with the impact of the COVID-19 pandemic in managing chronic pain were assessed from 2000 to 2020 in the FFS Medicare population of the United States. METHODS: The data for the analysis was obtained from the master database from the Centers for Medicare & Medicaid Services (CMS) physician/supplier procedure summary from 2000 to 2020. RESULTS: The results of the present investigation revealed an 18.7% decrease in utilization of all interventional techniques per 100,000 Medicare beneficiaries from 2019 to 2020, with a 19% decrease for epidural and adhesiolysis procedures, a 17.5% decrease for facet joint interventions and sacroiliac joint blocks, and a 25.4% decrease for disc procedures and other types of nerve blocks. The results differed from 2000 to 2010 with an annualized increase of 10.2% per 100,000 Medicare population compared to an annualized decrease of 0.4% from 2010 to 2019, and a 2.5% decrease from 2010 to 2020 for all interventional techniques. For epidural and adhesiolysis procedures decreases were more significant and annualized at 3.1% from 2010 to 2019, increasing the decline to 4.8% from 2010 to 2020. For facet joint interventions and sacroiliac joint blocks, the reversal of growth patterns was observed but maintained at an annualized rate increase of 2.1% from 2010 to 2019, which changed to a decrease of 0.01% from 2010 to 2020. Disc procedures and other types of nerve blocks showed similar patterns as epidurals with an 0.8% annualized reduction from 2010 to 2019, which was further reduced to 3.6% from 2010 to 2020 due to COVID-19. LIMITATIONS: Data for the COVID-19 pandemic impact were available only for 2019 and 2020 and only the FFS Medicare population was utilized; utilization patterns in Medicare Advantage Plans, which constitutes almost 40% of the Medicare enrollment in 2020 were not available. Moreover, this analysis shares the limitations present in all retrospective reviews of claims based datasets. CONCLUSION: The decline driven by the COVID-19 pandemic was 18.7% from 2019 to 2020. Overall decline in utilization in interventional techniques from 2010 to 2020 was 22.0% per 100,000 Medicare population, with an annual diminution of 2.5%, despite an increase in the population rate of 3.3% annualized (38.9% overall) and Medicare enrollees of 33.4% and 2.9% annually.

Background: Regenerative medicine interventions are applied to assist in the repair, and to potentially replace or restore damaged tissue through the use of autologous/allogenic biologics and it continues to expand. The anti-inflammatory, immunomodulatory, and regenerative properties of bone marrow mesenchymal stem cells (BM-MSCs), and investigation into their therapeutic efficacy and safety in patients with severe chronic low back pain, have not been demonstrated in controlled studies. Multiple pain generators have been hypothesized to be responsible in severe spinal degeneration and it is difficult to identify a single pain generator;consequently, resulting in inadequate therapeutic results. Objectives: The study was undertaken to evaluate the effectiveness of autologous bone marrow MSCs in the treatment of chronic low back pain due to severe lumbar spinal degeneration with involvement of multiple structures. Study Design: Prospective, open-label, nonrandomized, parallel-controlled, 2-arm exploratory study. Setting: A private, specialized, interventional pain management and regenerative medicine clinic. Methods: The treatment group patients received a one-time bone marrow concentrate injection into spinal structures (i.e., discs, facets, spinal nerves, and sacroiliac joints), along with conventional treatment, whereas, the control group received conventional treatment with nonsteroid antiinflammatory drugs, over-the-counter drugs, structured exercise programs, physical therapy, spinal injections and opioids, etc., as indicated. Outcomes Assessment: Outcomes were assessed utilizing multiple instruments, including the Oswestry Disability Index (ODI), Numeric Rating Scale (NRS-11), EuroQOL 5-Dimensional Questionnaire (EQ-5D-3L), Global Mental Health (GMH), and Global Physical Health (GPH). Multiple outcomes were assessed with primary outcomes being minimal clinically important differences (MCID) in ODI scores between the groups and/or a 2-point reduction in pain scores. In the study group, total nucleated cells, colony forming units-fibroblast, CD34-positive cell numbers and platelets were also recorded, along with post-procedure magnetic resonance imaging changes. Outcomes were assessed at 1, 3, 6, and 12 months. Results: Significant improvement was achieved in functional status measured by ODI, pain relief measured by NRS-11, and other parameters measured by EQ-5D-3L, GMH, and GPH, in the study group relative to the control group at all time periods. The results showed significant improvements at 12-month follow-up with 67% of the patients in the study group achieving MCID utilizing ODI when compared to 8% in the control group. Greater than 2-point pain reduction was seen in 74% of the patients at 3 months, 66% of the patients at 6 months, and 56% of the patients at 12 months. Both MCID and pain relief of 2 points were significantly different compared to the control group. Opioid use decreased in the investigational group, whereas, there was a slight increase in the control group. Age, gender, opioid use, and body mass index did not affect the outcomes in the stem cell group. Limitations: Single center, nonrandomized study. Conclusions: The first available controlled study utilizing BM-MSCs in severe degenerative spinal disease with interventions into multiple structures simultaneously, including disc, facet joints, nerve roots, and sacroiliac joint based on symptomatology, showed promising results.
