Background The past two decades have witnessed tremendous growth in the appreciation and treatment of sacroiliac joint (SIJ) complex pain, including anatomical dissections that shed light on innervation, an appreciation for the contribution of extra-articular components to SIJ complex pain, the advent of radiofrequency ablation (RFA) and a host of minimally-invasive surgical techniques. Yet, there is no standardization of diagnosis and treatment paradigms. Methods In February 2023, the Boards of Directors for the American Academy of Pain Medicine (AAPM) and American Society of Regional Anesthesia & Pain Medicine (ASRA-PM) approved the development of multispecialty guidelines on SIJ complex pain. Thirty partner organizations with clinical and scientific interests in SIJ complex pain were identified, and formal letters of request-for-participation were sent to each, along with a request for nominees to serve on the committee. Twenty five organizations agreed to participate in addition to the Departments of Defense and Veterans Affairs. A steering committee developed 21 questions, which spanned criteria for diagnosis, non-interventional and interventional treatments including surgery, technical parameters on how to optimize results, and what constitutes positive outcomes. Questions were methodically assigned to specialized modules comprising 4–5 members with complementary expertise, who collaborated with the Subcommittee Lead and one of three Committee Chairs to develop preliminary drafts. Following thorough revisions, these drafts were subsequently submitted to the full committee for comprehensive review. A modified Delphi method was used in which the answers to questions were sent to the committee en bloc and comments were returned in a non-blinded fashion to the Chairs, who incorporated the comments and sent out revised versions until consensus was achieved. During a committee meeting before commencement, it was agreed that recommendations would be noted when there was >50% agreement among committee members, but that a formal recommendation would require ≥75% consensus. Results Twenty-one organizations formally endorsed the guidelines. The American Society of Anesthesiologists, and American Academy of Physical Medicine & Rehabilitation, and the North American Spine Society affirmed the benefit of the guidelines but did not officially endorse them. The American Academy of Neurology declined to affirm the benefit of the guidelines citing ‘lack of relevance to their membership.’ Per policies, while the Departments of Defense and Veterans Affairs did not formally review the guidelines for endorsement, their representatives approved them. In addition to being endorsed or the benefit affirmed by all voting organizations, complete consensus from committee members was obtained on all 21 questions. On two recommendations, there were dissensions from three societies who thought that selecting patients for sacral lateral branch RFA and minimally-invasive fusion should be based on ≥75% relief from two blocks instead of at least 50% relief from a single block before RFA, and greater than 50% pain relief with documented functional improvement after a single block before fusion. One additional society (Latin American Society of Regional Anesthesia) abstained on the statement that the evidence is stronger for extra-articular than intra-articular injections. The committee found that a battery of physical exam tests has reasonable sensitivity, but lower specificity, for identifying intra-articular but not extra-articular pain, with negative tests having greater predictive value than positive ones. Intra-articular injections have diagnostic validity for SIJ intra-articular, but not extra-articular, pain. There is unclear or negative evidence for imaging. The prevalence rates of intra-articular and extra-articular pathology are comparable, with both intra- and extra-articular steroid injections providing at least 4 weeks of relief in well-selected patients. However, the evidence is slightly stronger for extra-articular corticosteroid injections to provide short-term relief. The evidence base for non-interventional therapies is indirect, extrapolated mostly from low back pain studies. There is weak evidence supporting dextrose-based prolotherapy and platelet-rich plasma to provide at least 3 months of pain relief. There is strong evidence for sacral lateral branch RFA to provide relief for at least 6 months in individuals with extra-articular pathology, with face validity and indirect evidence from randomized trials supporting sacral lateral branch blocks as a prognostic tool. There is stronger evidence for larger lesions or more aggressive lesioning strategies than for less stringent techniques. There is weak evidence to support non-steroidal anti-inflammatory drugs to prevent neuritis after RFA, and in most cases anticoagulation does not require cessation in the periprocedural period. With an aggressive lesioning strategy, sensory stimulation provides minimal therapeutic benefit, with weak, extrapolated evidence that motor stimulation can provide safety benefit. The cut-off to designate diagnostic or prognostic blocks as positive is most commonly set at 50%, with higher values not shown to improve outcomes for more definitive procedures; for therapeutic treatment outcomes, the evidence supports a lower threshold of ≥30% pain relief or meaningful benefit on non-pain outcomes (eg, opioid cessation) for designation of a positive response. For carefully selected patients with intra-articular SIJ complex pain based on controlled blocks who have failed conservative therapies, there is weak or very weak evidence that minimally invasive SIJ fusion can provide benefit for at least one year. Conclusions SIJ complex pain remains an underappreciated source of chronic low back pain, affecting between 15% and 30% of patients with axial pain predominantly below L5. Answers to many questions were limited by low-quality evidence, indicating the need for better research. SIJ complex pain is a multifarious condition (ie, pain can be from different portions of both the intra- and extra-articular components of the joint) for which an interdisciplinary, multimodal treatment plan can optimize treatment outcomes.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Adult Cancer Pain provide recommendations for the comprehensive management of pain in patients with cancer. This article will focus on methods for screening for pain, safe and appropriate prescription of opioid and miscellaneous analgesics, and the optimization of nonpharmacologic interventions including integrative and interventional strategies for treatment of cancer-related pain. Additionally, the NCCN Guidelines discuss methods for the safe reduction of opioids when appropriate, as well as techniques for encouraging the judicious use of opioids. The complete version of the NCCN Guidelines for Adult Cancer Pain addresses additional issues that are not covered here, including management of pain during a pain crisis, management of procedure-related pain and anxiety, pain management for cancer survivors, and the use of nonopioid and adjuvant analgesics for cancer-related pain.

Abstract Introduction The Accreditation Council for Graduate Medical Education (ACGME) approved the first pain medicine fellowship programs over three decades ago, designed around a pharmacological philosophy. Following that, there has been a rise in the transition of pain medicine education toward a multidisciplinary interventional model based on a tremendous surge of contemporaneous literature in these areas. This trend has created variability in clinical experience and education amongst accredited pain medicine programs with minimal literature evaluating the differences and commonalities in education and experience of different pain medicine fellowships through Program Director (PD) experiences. This study aims to gather insight from pain medicine fellowship program directors across the country to assess clinical and interventional training, providing valuable perspectives on the future of pain medicine education. Methods This study involved 56 PDs of ACGME‐accredited pain fellowship programs in the United States. The recruitment process included three phases: advanced notification, invitation, and follow‐up to maximize response rate. Participants completed a standard online questionnaire, covering various topics such as subcategory fields, online platforms for supplemental education, clinical experience, postgraduate practice success, and training adequacy. Results Surveys were completed by 39/56 (69%) standing members of the Association of Pain Program Directors (APPD). All PDs allowed fellows to participate in industry‐related and professional society‐related procedural workshops, with 59% encouraging these workshops. PDs emphasized the importance of integrity, professionalism, and diligence for long‐term success. Fifty‐four percent of PDs expressed the need for extension of fellowship training to avoid supplemental education by industry or pain/spine societies. Conclusion This study highlights the challenge of providing adequate training in all Pain Medicine subtopics within a 12‐month pain medicine fellowship. PDs suggest the need for additional training for fellows and discuss the importance of curriculum standardization.

This Practice Advisory presents a comprehensive and evidence-based set of position statements and recommendations for the use of contrast media in interventional pain procedures. The advisory was established by an international panel of experts under the auspices of 11 multinational and multispecialty organizations based on a comprehensive review of the literature up to December 31, 2019. The advisory discusses the risks of using gadolinium-based contrast agents. These include nephrogenic systemic fibrosis, gadolinium brain deposition/retention, and encephalopathy and death after an unintentional intrathecal gadolinium injection. The advisory provides recommendations on the selection of a specific gadolinium-based contrast agent in patients with renal insufficiency, those who had multiple gadolinium-enhanced magnetic resonance imaging examinations, and in cases of paraspinal injections. Additionally, recommendations are made for patients who have a history of mild, moderate, or severe hypersensitivity reactions to contrast medium.

Abstract Background Pain fellowship programs are facing unique challenges during the COVID-19 pandemic. Restrictions by state governments and the Centers for Disease Control and Prevention have resulted in a rapidly changing and evolving learning environment for today’s fellows. Innovative solutions must be sought to maintain proper education and ensure the well-being of our trainees. Methods We assembled a panel of pain program directors who serve as officers/board members of the Association of Pain Program Directors, offering guidance and recommendations to pain fellowship directors nationwide. Panel members evaluate the best available evidence and expert opinion on use of remote and virtual platforms in clinical care, adaptability to alterations in clinic and referral management, and provide guidance on postgraduate impact. Conclusions The country is in the midst of an unprecedented pandemic. The impact on pain management fellowships has been significant and will likely last for months, resulting in extraordinary challenges to the administration of pain fellowship programs and the education of our fellows. Several strategies will help address these challenges, including employing telehealth capabilities to continue clinical experiences and providing trainees with opportunities to continue their professional growth beyond fellowship completion. Together, we can implement innovative solutions to overcome these challenges.

Abstract Background Pain fellowship programs are facing unique challenges during the COVID-19 pandemic. Restrictions from state governments and the Centers for Disease Control and Prevention have resulted in a rapidly changing and evolving learning environment for todays’ fellows. Innovative solutions must be sought to guarantee that proper education is maintained and to ensure the well-being of our trainees. Methods We assembled a panel of pain program directors who serve as officers/board members of the Association of Pain Program Directors to provide guidance and formulate recommendations to pain fellowship directors nationally. This guidance is based on reviewing current changes to the Accreditation Council for Graduate Medical Education (ACGME) and American Board of Anesthesiology policies and best available evidence and expert opinion on the use of remote educational activities, research endeavors, and trainee wellness. Conclusions The country is in the midst of an unprecedented pandemic. The impact on pain management fellowships has been severe and will likely last for months, resulting in extraordinary challenges to the administration of pain fellowship programs and the education of our fellows. Understanding revisions to ACGME policies, using technology to promote remote learning opportunities, and providing trainees with opportunities to alleviate their anxiety and encourage mental health are beneficial strategies to implement. Together, we can implement innovative solutions to help overcome these challenges.
