Extensive research into potential sources of neck pain and referred pain into the upper extremities and head has shown that the cervical facet joints can be a potential pain source confirmed by precision, diagnostic blocks.Systematic review and meta-analysis utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, quality assessment of the included studies, conventional and single-arm meta-analysis, and best evidence synthesis.The objective of this systematic review and meta-analysis is to evaluate the effectiveness of radiofrequency neurotomy as a therapeutic cervical facet joint intervention in managing chronic neck pain.Available literature was included. Methodologic quality assessment of studies was performed from 1996 to September 2021. The level of evidence of effectiveness was determined.Based on the qualitative and quantitative analysis with single-arm meta-analysis and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system of appraisal, with inclusion of one randomized controlled trial (RCT) of 12 patients in the treatment group and eight positive observational studies with inclusion of 589 patients showing positive outcomes with moderate to high clinical applicability, the evidence is level II in managing neck pain with cervical radiofrequency neurotomy. The evidence for managing cervicogenic headache was level III to IV with qualitative analysis and single-arm meta-analysis and GRADE system of appraisal, with the inclusion of 15 patients in the treatment group in a positive RCT and 134 patients in observational studies. An overwhelming majority of the studies produced multiple lesions.There was a paucity of literature and heterogeneity among the available studies.This systematic review and meta-analysis shows level II evidence with radiofrequency neurotomy on a long-term basis in managing chronic neck pain with level III to IV evidence in managing cervicogenic headaches.The online version contains supplementary material available at 10.1007/s40122-022-00455-0.

In the United States, the prevalence of opioid use disorders has increased in recent years along with an attendant rise in the incidence of chronic pain disorders and prescription opioid use. Patient navigation services have been used to improve health outcomes in cancer and other chronic disease states, but it is unclear whether the implementation of patient navigation services can facilitate improved outcomes among patients receiving chronic opioid therapy.The objective of this study was to compare the outcomes of patients receiving chronic opioid therapy plus patient navigation services and those receiving chronic opioid therapy as a part of usual care.This was a prospective, observational study. Consecutive patients receiving chronic opioid therapy were enrolled, with alternating assignments to patient navigation (n = 30) or usual care (n = 30). Participants in the patient navigation group received support from a non-physician, non-advanced practice provider staff member who initiated frequent contact via telephone, telemedicine, or in-clinic visits to discuss the patient's health goals. The minimum follow-up period was 90 days. Outcomes qualitatively compared across groups included final pain score, final morphine milligram equivalent (MME) per day, and discharge rates. Risk factors for discharge within the navigation group were assessed. Patient feedback was also solicited.This study was conducted at a single independent pain clinic in the United States.Demographic features were similar between the navigator group and the control group. The control group had a higher average initial pain score (7.0/10) than the intervention group (5.9/10) and were receiving a higher initial dose of opioids (23.1 vs 19.0 MME/d). After an average follow-up of 108.7 days, patients in the navigator group had a 16% decrease in final opioid dose compared with a 23% increase in the control group. Furthermore, patients in the control group were discharged from the practice at a higher rate (23.3% vs 6.6%), suggesting increased opioid misuse in the control group compared with the navigator group. In the navigator group, higher levels of anxiety and depression were the primary predictors of discharge.This was a single-center study with a small sample size. The generalizability of these results to other clinic settings is unknown.Patient navigation decreased opioid use and practice discharge compared with usual care in an independent pain clinic, suggesting a role for patient navigation in reducing opioid misuse and potentially reducing adverse events.

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.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.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.The data for the analysis was obtained from the master database from the Centers for MedicareMedicaid Services (CMS) physician/supplier procedure summary from 2000 to 2020.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.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.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.

Among the multiple causes of low back and lower extremity pain, sacroiliac joint pain has shown to be prevalent in 10% to 25% of patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis. Over the years, multiple Current Procedural Terminology (CPT) codes have evolved with the inclusion of intraarticular injections, nerve blocks, and radiofrequency neurotomy, in addition to percutaneous sacroiliac joint fusions. Previous assessments of utilization patterns of sacroiliac joint interventions only included sacroiliac joint intraarticular injections, since the data was not available prior to the introduction of new codes. A recent assessment revealed an increase of 11.3%, and an annual increase of 1.2% per 100,000 Medicare population from 2009 to 2018, showing a decline in growth patterns. During the past 2 years, the COVID-19 pandemic has also had significant effects on the utilization patterns of sacroiliac joint interventions.The impact of the COVID-19 pandemic and analysis of growth patterns of sacroiliac joint interventions (intraarticular injections, nerve blocks, radiofrequency neurotomy, arthrodesis and fusion) was evaluated from 2010 to 2019 and 2010 to 2020, with a comparative analysis from 2019 to 2020 to assess the impact of the COVID-19 pandemic.To update utilization patterns of sacroiliac joint interventions with assessment of the impact of the COVID-19 pandemic.The Centers for Medicare and Medicaid Services (CMS) Physician/Supplier Procedure Summary (PSPS) Master dataset was utilized in the present analysis.The results of this evaluation demonstrated a significant impact of the COVID-19 pandemic with a 19.2% decrease of utilization of sacroiliac joint intraarticular injections from 2019 to 2020. There was a 23.3% increase in sacroiliac joint arthrodesis and a 5.3% decrease for sacroiliac joint fusions with small numbers from 2019 to 2020. However, data was not available for sacroiliac joint nerve blocks and sacroiliac joint radiofrequency neurotomy as these codes were incorporated in 2020. Overall, from 2010 to 2019, sacroiliac joint intraarticular injections showed an annual increase of 0.9% per 100,000 Medicare population. Sacroiliac joint arthrodesis and fusion showed an annual increase from 2010 to 2020 per 100,000 Medicare population of 29% for arthrodesis and 13.3% for fusion.Limitations of this study include a lack of inclusion of Medicare Advantage patients constituting approximately 30% to 40% of the overall Medicare population. As with all claims-based data analyses, this study is retrospective and thus potentially limited by bias. Finally, patients who are non-Medicare are not part of the dataset.The study shows the impact of the COVID-19 pandemic with a significant decrease of intraarticular injections of 19.2% from 2019 to 2020 per 100,000 Medicare population. These decreases of intraarticular injections are accompanied by a 5.3% decrease of fusion, but a 23.3% increase of arthrodesis from 2019 to 2020 per 100,000 Medicare population. Overall, the results showed an annual increase of 0.9% per 100,000 Medicare population for intraarticular injections, a 35.4% annual increase for sacroiliac joint arthrodesis and an increase of 15.5% for sacroiliac joint fusion from 2010 to 2019.

In the midst of the COVID-19 pandemic, data has shown that age-adjusted overdose death rates involving synthetic opioids, psychostimulants, cocaine, and heroin have been increasing, including prescription opioid deaths, which were declining, but, recently, reversing the trends. Contrary to widely held perceptions, the problem of misuse, abuse, and diversion of prescription opioids has been the least of all the factors in recent years. Consequently, it is important to properly distinguish between the role of illicit and prescription opioids in the current opioid crisis. Multiple efforts have been based on consensus on administrative policies for certain harm reduction strategies for individuals actively using illicit drugs and reducing opioid prescriptions leading to curbing of medically needed opioids, which have been ineffective. While there is no denial that prescription opioids can be misused, abused, and diverted, the policies have oversimplified the issue by curbing prescription opioids and the pendulum has swung too far in the direction of severely limiting prescription opioids, without acknowledgement that opioids have legitimate uses for persons suffering from chronic pain. Similar to the opioid crisis, interventional pain management procedures have been affected by various policies being applied to reduce overuse, abuse, and finally utilization. Medical policies have been becoming more restrictive with reduction of access to certain procedures, with the pendulum swinging too far in the direction of limiting interventional techniques. Recent utilization assessments have shown a consistent decline for most interventional techniques, with a 18.7% decrease from 2019 to 2020. The causes for these dynamic changes are multifactorial likely including the misapplication of the 2016 Centers for Disease Control and Prevention (CDC) guidelines for prescribing opioids for chronic pain, the relative ease of access to illicit synthetic opioids and more recently issues related to the COVID-19 pandemic. In addition, recent publications have shown association of dose tapering with overdose or mental health crisis among patients prescribed long-term opioids. These findings are leading to the hypothesis that federal guidelines may inadvertently be contributing to an increase in overall opioid deaths and diminished access to interventional techniques. Together, these have resulted in a fourth wave of the opioid epidemic.A narrative review.The fourth wave results from a confluence of multiple factors, including misapplication of CDC guidelines, the increased availability of illicit drugs, the COVID-19 pandemic, and policies reducing access to interventional procedures. The CDC guidelines and subsequent regulatory atmosphere have led to aggressive tapering up to and including, at times, the overall reduction or stoppage of opioid prescriptions. Forced tapering has been linked to an increase of 69% for overdoses and 130% for mental health crisis. The data thus suggests that the diminution in access to opioid prescriptions may be occurring simultaneously with an increase in illicit narcotic use.Combined with CDC guidelines, the curbing of opioid prescriptions to medically needed individuals, among non-opioid treatments, interventional techniques have been affected with declining utilization rates and medical policies reducing access to such modalities.The opioid overdose waves over the past three decades have resulted from different etiologies. Wave one was associated with prescription opioid overdose deaths and wave two with the rise in heroin and overdose deaths from 1999 to 2013. Wave three was associated with a rise in synthetic opioid overdose deaths. Sadly, wave four continues to escalate with increasing number of deaths as a confluence of factors including the CDC guidelines, the COVID pandemic, increased availability of illicit synthetic opioids and the reduction of access to interventional techniques, which leads patients to seek remedies on their own.

Chronic spinal pain is the most prevalent chronic disease, with chronic persistent spinal pain lasting longer than one-year reported in 25% to 60% of the patients. Health care expenditures have been escalating and the financial impact on the US economy is growing. Among multiple modalities of treatments available, facet joint interventions and epidural interventions are the most common ones, in addition to surgical interventions and numerous other conservative modalities of treatments. Despite these increasing costs in the diagnosis and management, disability continues to increase. Consequently, algorithmic approaches have been described as providing a disciplined approach to the use of spinal interventional techniques in managing spinal pain. This approach includes evaluative, diagnostic, and therapeutic approaches, which avoids unnecessary care, as well as poorly documented practices. Recently, techniques involving artificial intelligence and machine learning have been demonstrated to contribute to the improved understanding, diagnosis, and management of both acute and chronic disease in line with well-designed algorithmic approach. The use of artificial intelligence and machine-learning techniques for the diagnosis of spinal pain has not been widely investigated or adopted.To evaluate whether it is possible to use artificial intelligence via machine learning algorithms to analyze specific data points and to predict the most likely diagnosis related to spinal pain.This was a prospective, observational pilot study.A single pain management center in the United States.A total of 246 consecutive patients with spinal pain were enrolled. Patients were given an iPad to complete a Google form with 85 specific data points, including demographic information, type of pain, pain score, pain location, pain duration, and functional status scores. The data were then input into a decision tree machine learning software program that attempted to learn which data points were most likely to correspond to the practitioner-assigned diagnosis. These outcomes were then compared with the practitioner-assigned diagnosis in the chart.The average age of the included patients was 57.4 years (range, 18-91 years). The majority of patients were women and the average pain history was approximately 2 years. The most common practitioner-assigned diagnoses included lumbar radiculopathy and lumbar facet disease/spondylosis. Comparison of the software-predicted diagnosis based on reported symptoms with practitioner-assigned diagnosis revealed that the software was accurate approximately 72% of the time.Additional studies are needed to expand the data set, confirm the predictive ability of the data set, and determine whether it is broadly applicable across pain practices.Software-predicted diagnoses based on the data from patients with spinal pain had an accuracy rate of 72%, suggesting promise for augmented decision making using artificial intelligence in this setting.

As with many others in the house of medicine, the COVID-19 pandemic has adversely impacted the practice of interventional pain management. This in part relates to various state health authority or medical board restrictions with reductions in patient volume for evaluations, follow-ups, and procedures. Of course, the pandemic continues to persist which is in turn leading to longer-lasting effects. Our previous survey was performed in March 2020. At that time, there was a national lockdown in the United States with COVID-19 disease qualifying as a pandemic by the World Health Organization (WHO). The pandemic caused by COVID-19 disease continues to have far-reaching implications on how we deliver routine care to patients and its effect on patient care, economic aspects, and health of interventional pain management providers.To assess the current and expected future impact of the COVID-19 pandemic on interventional pain management practices in a physician survey. The study was performed based on performance in 2021 compared to the 2019 pre-COVID era.The American Society of Interventional Pain Physicians (ASIPP) administered a 16-question survey to their members by contacting them via a commercially available online marketing company platform. The survey was completed on www.constantcontact.com.The results showed that 88% of the providers experienced a reduction in income and a similar number expect decreases over the next 12 months. A large proportion of respondents (73.3%) reported a reduction in revenue of 11%-25%. In contrast, another 21.5% reported a revenue decline of 26%-50%, and 29% reported 11%-25% increase in expenses. Overall, new patient volume decreased 11%-25% based on the response from almost 63%, whereas almost 9% reported a decline of 26%-50%. In contrast, established patient volume declined 1%-10% as reported by 64% of the respondents, compared to an 11%-25% decrease by a small proportion of 14%. All interventional procedures showed significant decreases across the board, with 69% of the respondents reporting a decline in-office procedures, 64% in ambulatory surgery center (ASC) procedures, and 57% in hospital outpatient department (HOPD) procedures, ranging from 11%-25%.The survey included a relatively small number of member physicians which could introduce sampling error. Consequently, it may not be generalizable for other specialties or even to pain medicine.The COVID-19 pandemic has put interventional pain practices throughout the United States under considerable financial and psychological stress. This study seeks to quantify the extent of economic loss and other challenges resultant from the pandemic. Almost 99% reported a decrease in revenues in the last 12 months, with 86% reporting an expected reduction in the next 12 months and 49% reporting an increase in expenses. Declines have been reported in all sectors with new patients, office procedures, ASC, and HOPD procedures, except for established patient visits, which have shown minor declines compared to other domains. Understanding the issues facing interventional pain management physicians facilitates the development of strategies to actively manage provider practice/well-being, and to minimize risk to personnel to keep patients safe.

Traditional pain assessment methods have significant limitations due to the high variability in patient reported pain scores and perception of pain by different individuals. There is a need for generalized and automatic pain detection and recognition methods. In this paper, state-of-the-art machine learning (ML) and deep learning methods in this field are analyzed as well as pain management techniques.The objective of the study is to analyze the current use of artificial intelligence (AI) and ML in the analysis and management of pain and to disseminate this knowledge prompting future utilization by medical professionals.A narrative review of the literature focusing on the latest algorithms in AI and ML for pain assessment and management.Research studies were collected using a literature search on PubMed, Science Direct and IEEE Xplore between 2018 and 2020.The results of our assessment resulted in the identification of 47 studies meeting inclusion criteria. Pain assessment was the most studied subject with 11 studies, followed by automated measurements with 10 studies, spinal diagnosis with 8 studies, facial expression with 7 studies, pain assessment in special settings evaluated in 5 studies, 4 studies described treatment algorithms, and 2 studies assessed neonatal pain. These studies varied from simple to highly complex methodology. The majority of the studies suffered from inclusion of a small number of patients and without replication of results. However, considering AI and ML are dynamic and emerging specialties, the results shown here are promising. Consequently, we have described all the available literature in summary formats with commentary. Among the various assessments, facial expression and spinal diagnosis and management appear to be ready for inclusion as we continue to progress.This review is not a systematic review of ML and AI applications in pain research. This review only provides a general idea of the upcoming techniques but does not provide an authoritative evidence-based conclusive opinion of their clinical application and effectiveness.While a majority of the studies focused on classification tasks, very few studies have explored the diagnosis and management of pain. Usage of ML techniques as support tools for clinicians holds an immense potential in the field of pain management.

Chronic low back pain secondary to facet joint pathology is prevalent in 27% to 40% of selected populations using controlled comparative local anesthetic blocks. Lumbar facet joint nerve blocks and radiofrequency neurotomy are the most common interventional procedures for lower back pain. Nonetheless, questions remain regarding the effectiveness of each modality. Moreover, there is no agreement in reference to superiority or inferiority of lumbar facet joint nerve blocks when compared with radiofrequency neurotomy. Centers for Medicare and Medicaid Services (CMS) and almost all payers prefer radiofrequency ablation. Both procedures have been extensively studied with randomized controlled trials, systematic reviews, and cost utility analysis.To assess the clinical outcomes and cost utility of therapeutic lumbar facet joint nerve blocks (lumbar facet joint nerve blocks with L5 dorsal ramus block) compared with radiofrequency neurotomy in managing chronic low back pain of facet joint origin.A retrospective, case-control, comparative evaluation of outcomes and cost utility.The study was conducted in an interventional pain management practice, a specialty referral center, a private practice setting in the United States.The study was performed utilizing the Strengthening the Reporting of Observational Studies in Epidemiology Analysis (STROBE) criteria. Only the patients meeting the diagnostic criteria of facet joint pain by means of comparative, controlled diagnostic local anesthetic blocks were included.The main outcome measure was pain relief measured by the Numeric Rating Scale (NRS) evaluated at 3, 6, and 12 months. Significant improvement was defined as at least 50% improvement in pain relief. Cost utility was calculated utilizing direct payment data for the procedures with the addition of estimated indirect costs over a period of one year based on highly regarded surgical literature and previously published interventional pain management literature.A total of 326 patients met the inclusion criteria with 99 patients receiving lumbar facet joint nerve blocks (lumbar facet joint nerve blocks with L5 dorsal ramus block) and 227 receiving lumbar radiofrequency neurotomy. Forty-eight patients in the facet joint nerve block group and 148 patients in the radiofrequency group completed one-year follow-up. Patients experienced significant improvement in both groups from baseline to 12 months with significant pain relief (≥ 50%) Significant pain relief was recorded in 100%, 99%, and 79% of the patients in the facet joint nerve block group, whereas, it was 100%, 74%, and 65% in the radiofrequency neurotomy group at the 3, 6, and 12 month follow-up, with a significant difference at 6 months. Cost utility analysis showed average costs for quality-adjusted life year (QALY) of $4,664 for lumbar facet joint nerve blocks and $5,446 for lumbar radiofrequency neurotomy. Twelve patients (12%) in the lumbar facet joint nerve block group and 79 patients (35%) in the lumbar radiofrequency group were converted to other treatments, either due to side effects or inadequate relief.This study shows similar outcomes of therapeutic lumbar facet joint nerve blocks when compared with radiofrequency neurotomy as indicated by significant pain relief and cost utility.
