Treatment Disparities in Hispanic Patients with Chronic Pain: An Evidence-Based Narrative Review.

PURPOSE OF REVIEW: The purpose of this narrative review is to summarize healthcare disparities experienced by Hispanic and Latino/Latinx patients with chronic pain, evaluate the existing literature exploring the specific therapeutic inequities affecting this patient population, and identify gaps in the literature requiring future study. RECENT FINDINGS: Hispanic and Latino/Latinx patients experience disparities in chronic pain management. They are less likely to be prescribed pharmacologic therapies, including non-steroidal anti-inflammatory drugs and opioids. Hispanic and Latino/Latinx patients are also less likely to receive spinal cord stimulators and may be charged higher costs for them. There are no published studies specifically assessing Hispanic and Latino/Latinx patients' utilization and outcomes from other common interventional pain procedures (e.g., epidural steroid injections, radiofrequency ablation). Limited data suggest non-pharmacologic treatments, such as cognitive behavioral therapy and complementary/integrative health modalities, might have more benefit for this population, potentially because of greater utilization. Hispanic and Latino/Latinx patients experience disparities in chronic pain management. There is a paucity of data available pertaining specifically to pain-related outcomes and the utilization of pain treatment modalities, especially in regard to interventional procedures. Additional research is urgently needed in order to understand the full extent of these disparities and develop solutions to provide more equitable care.

Multicenter, Randomized, Placebo-controlled Crossover Trial Evaluating Topical Lidocaine for Mechanical Cervical Pain.

BACKGROUND: There are few efficacious treatments for mechanical neck pain, with controlled trials suggesting efficacy for muscle relaxants and topical nonsteroidal anti-inflammatory drugs. Although studies evaluating topical lidocaine for back pain have been disappointing, the more superficial location of the cervical musculature suggests a possible role for topical local anesthetics. METHODS: This study was a randomized, double-blind, placebo-controlled crossover trial performed at four U.S. military, Veterans Administration, academic, and private practice sites, in which 76 patients were randomized to receive either placebo followed by lidocaine patch for 4-week intervals (group 1) or a lidocaine-then-placebo patch sequence. The primary outcome measure was mean reduction in average neck pain, with a positive categorical outcome designated as a reduction of at least 2 points in average neck pain coupled with at least a 5-point score of 7 points on the Patient Global Impression of Change scale at the 4-week endpoint. RESULTS: For the primary outcome, the median reduction in average neck pain score was -1.0 (interquartile range, -2.0, 0.0) for the lidocaine phase versus -0.5 (interquartile range, -2.0, 0.0) for placebo treatment (P = 0.17). During lidocaine treatment, 27.7% of patients experienced a positive outcome versus 14.9% during the placebo phase (P = 0.073). There were no significant differences between treatments for secondary outcomes, although a carryover effect on pain pressure threshold was observed for the lidocaine phase (P = 0.015). A total of 27.5% of patients in the lidocaine group and 20.5% in the placebo group experienced minor reactions, the most common of which was pruritis (P = 0.36). CONCLUSIONS: The differences favoring lidocaine were small and nonsignificant, but the trend toward superiority of lidocaine suggests more aggressive phenotyping and applying formulations with greater penetrance may provide clinically meaningful benefit.

Antimicrobial therapies for chronic pain (part 1): analgesic mechanisms.

There is increasing evidence that the relationship between chronic pain and infections is complex and intertwined. Bacterial and viral infections can cause pain through numerous mechanisms such as direct tissue damage and inflammation, the induction of excessive immunologic activity, and the development of peripheral or central sensitization. Treating infections might relieve pain by attenuating these processes, but a growing body of literature suggests that some antimicrobial therapies confer analgesic effects, including for nociceptive and neuropathic pain symptoms, and affective components of pain. The analgesic mechanisms of antimicrobials are indirect, but might be conceptualized into two broad categories: 1) the reduction of the infectious burden and associated pro-inflammatory processes; and 2) the inhibition of signaling processes (e.g., enzymatic and cytokine activity) necessary for nociception and maladaptive neuroplastic changes via off-target effects (unintended binding sites). For the former, there is evidence that symptoms of chronic low back pain (when associated with Modic type 1 changes), irritable bowel syndrome, inflammatory bowel disease, chronic pelvic pain, and functional dyspepsia might be improved after antibiotic treatment, though significant questions remain regarding specific regimens and dose, and which subpopulations are most likely to benefit. For the latter, there is evidence that several antimicrobial classes and medications exert analgesic effects independent of their reduction of infectious burden, and these include cephalosporins, ribavirin, chloroquine derivatives, rapalogues, minocycline, dapsone, and piscidin-1. This article aims to comprehensively review the existing literature for antimicrobial agents that have demonstrated analgesic efficacy in preclinical or clinical studies.

Antimicrobial therapies for chronic pain (part 2): the prevention and treatment of chronic pain.

The discovery and development of antimicrobial therapies represents one of the most significant advancements in modern medicine. Although the primary therapeutic intent of antimicrobials is to eliminate their target pathogens, several antimicrobials have been shown to provide analgesia as a secondary benefit. Antimicrobials have demonstrated analgesic effects in conditions that involve dysbiosis or potential subclinical infection (e.g ., chronic low back pain with Modic type 1 changes; chronic prostatitis/chronic pelvic pain; irritable bowel syndrome; inflammatory bowel disease; functional gastrointestinal disorders/dyspepsia; myalgic encephalomyelitis/chronic fatigue syndrome), and might even prevent the chronification of pain after acute infections that are associated with excessive systemic inflammation (e.g ., post COVID-19 condition/long Covid, rheumatic fever). Clinical studies often assess the analgesic effects of antimicrobial therapies in an observational manner, without the ability to identify causative relationships, and significant gaps in the understanding remain regarding the analgesic potential of antimicrobials. Numerous interrelated patient-specific, antimicrobial-specific, and disease-specific factors altogether contribute to the perception and experience of pain, and each of these requires further study. Given worldwide concerns regarding antimicrobial resistance, antimicrobials must continue to be used judiciously and are unlikely to be repurposed as primary analgesic medications. However, when equipoise exists among several antimicrobial treatment options, the potential analgesic benefits of certain antimicrobial agents might be a valuable aspect to consider in clinical decision-making. This article (the second in a two-part series) aims to comprehensively review the evidence on the prevention and treatment of chronic pain using antimicrobial therapies and suggest a framework for future studies on this topic.

Scrambler Therapy for Patients With Complex Regional Pain Syndrome: A Case Series.

Complex regional pain syndrome is a chronic debilitating pain disorder that is difficult to manage, in part due to its heterogeneous clinical presentation and lack of clearly defined pathophysiology. Patients usually require a multidisciplinary approach to treatment, which can entail pharmacotherapy, physical therapy, behavioral therapy, and interventional pain procedures, such as sympathetic nerve blocks, spinal cord stimulation, and dorsal root ganglion stimulation. However, many patients continue to experience pain refractory to these multimodal strategies. Scrambler therapy (ST) is a noninvasive method of neuromodulation that is applied through cutaneous electrodes, and can alleviate chronic neuropathic pain by stimulating C-fibers and replacing endogenous pain signals with synthetic non-nociceptive signals. Although the use of ST has been reported for several types of refractory central and peripheral neuropathic pain, there is a paucity of data regarding the use of ST for complex regional pain syndrome. We present two patients with complex regional pain syndrome of the right lower extremity, who each underwent ST and experienced significant pain relief and improvement in function and quality of life.

Nonorganic (Behavioral) Signs and Their Association With Epidural Corticosteroid Injection Treatment Outcomes and Psychiatric Comorbidity in Cervical Radiculopathy: A Multicenter Study.

OBJECTIVE: To determine the association between cervical nonorganic pain signs and epidural corticosteroid injection outcomes and coexisting pain and psychiatric conditions. PATIENTS AND METHODS: Seventy-eight patients with cervical radiculopathy who received epidural corticosteroid injection were observed to determine the effects that nonorganic signs have on treatment outcome. A positive outcome was a decrease of 2 or more points in average arm pain, coupled with a score of 5 on a 7-point Patient Global Impression of Change scale 4 weeks after treatment. Nine tests in 5 categories (abnormal tenderness, regional disturbances deviating from normal anatomy, overreaction, discrepancies in examination findings with distraction, and pain during sham stimulation) were modified from previous studies and standardized. Other variables examined for their association with nonorganic signs and outcomes included disease burden, psychopathology, coexisting pain conditions, and somatization. RESULTS: Of the 78 patients, 29% (n=23) had no nonorganic signs, 21% (n=16) had signs in 1 category, 10% (n=8) had signs in 2 categories, 21% (n=16) had signs in 3 categories, 10% (n=8) had signs in 4 categories, and 9% (n=7) had signs in 5 categories. The most common nonorganic sign was superficial tenderness (44%; n=34). Mean number of positive nonorganic categories was higher in individuals with negative treatment outcomes (2.5±1.8; 95% CI, 2.0 to 3.1) compared with those with positive outcomes (1.1±1.3; 95% CI, 0.7 to 1.5; P=.0002). Negative treatment outcomes were most strongly associated with regional disturbances and overreaction. Positive associations were noted between nonorganic signs and multiple pain (P=.011) and multiple psychiatric (P=.028) conditions. CONCLUSION: Cervical nonorganic signs correlate with treatment outcome, pain, and psychiatric comorbidities. Screening for these signs and psychiatric symptoms may improve treatment outcomes. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04320836.

The Use of Scrambler Therapy in Treating Chronic Pain Syndromes: A Systematic Review.

BACKGROUND: Scrambler therapy (ST) is a noninvasive method of transcutaneous neuromodulation that has 510(K) clearance from the United States Food and Drug Administration for treating acute pain, postoperative pain, and intractable chronic pain. Since its inception, ST has been used to treat many chronic pain syndromes in a variety of patient populations. We synthesized the available literature for ST to delineate its overall evidence basis. MATERIALS AND METHODS: We performed a systematic review based on conventional Preferred Reporting Items for Systematic Reviews and Meta-Analyses methods by surveying multiple data sources from January 1950 through October 2021. Two review authors, independently and in a standardized, unblinded fashion, conducted a systematic review to identify relevant studies and extract the necessary outcome measures. A conservative search strategy was implemented to identify all ST studies for the treatment of chronic pain syndromes. Primary outcome parameters collected were analgesic benefit, adverse effects, and other metrics such as sensorimotor testing. RESULTS: A total of 21 studies met the final criteria for study inclusion and comprised randomized controlled trials (n = 8), prospective observational studies (n = 10), and retrospective cohort studies (n = 3). Nearly all the reported studies explored the use of ST for the treatment of neuropathic pain, with chemotherapy-induced peripheral neuropathy being the most studied condition. Most studies were limited by small cohorts but reported ST being safe, well tolerated, and providing clinically meaningful pain reduction. The duration of posttreatment follow-up ranged from ten to 14 days (concordant with completion of typical ST protocols) to three months. Secondary benefits such as medication reduction and improvement of sensory and motor symptoms were noted by some studies. CONCLUSIONS: ST is regarded as a safe intervention with potential for significant analgesic benefit for neuropathic pain conditions. Although the available evidence is most robust for treating chemotherapy-induced peripheral neuropathy, ST has also been shown to be effective in treating other neuropathic pain syndromes. Evidence for ST use in nociceptive pain conditions is limited but appears promising. The favorable safety profile and increasing evidence basis for ST warrant more extensive recognition and consideration for use in clinical care.

Safety of Scrambler Therapy: A Systematic Review of Complications and Adverse Effects.

OBJECTIVE: The objective was to qualitatively synthesize all reported cases of complications, adverse effects, side effects, or harms arising from the use of scrambler therapy (ST). METHODS AND DESIGN: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The PubMed, Embase, Scopus, Web of Science, United States National Library of Medicine clinical trials registry, and Cochrane Central Register of Controlled Trials databases were searched from database inception to December 10, 2021. Case reports/series, abstracts, retrospective studies, and prospective studies (e.g., open-label trials, randomized controlled trials) pertaining to ST and any description of a complication, adverse effect, side effect, or harm were screened. The search protocol was developed a priori and registered via the International Prospective Register of Systematic Reviews (PROSPERO ID: CRD42021291838). RESULTS: A total of six RCTs, 19 prospective open-label trials, and 11 case series / case reports met the inclusion criteria, comprising 1,152 total patients. Two patients experienced contact dermatitis, and one patient reported minor ecchymosis that resolved without intervention. This yielded a composite complication rate of 0.26% (3/1,152). There were zero reported serious adverse events. CONCLUSIONS: When used in accordance with the treatment protocols described by the United States Food and Drug Administration and device manual, ST is associated with a reported composite complication rate that is orders of magnitude lower than those of invasive neuromodulation devices. ST neuromodulation is a safe alternative for patients who cannot undergo invasive neuromodulation device implantation because of either risk or preference.

Painful Diabetic Neuropathy - Spinal Cord Stimulation, Peripheral Nerve Stimulation, Transcutaneous Electrical Nerve Stimulation, and Scrambler Therapy: A Narrative Review.

BACKGROUND: First-line medications for the treatment of painful diabetic neuropathy (PDN) are associated with a substantial rate of discontinuation due to adverse effects or insufficient efficacy. Neuromodulation techniques have been used for PDN, but a comprehensive review of the literature that incorporates several distinct device categories has yet to be undertaken. OBJECTIVES: We aimed to summarize the evidence regarding 4 major types of neuromodulation devices for the treatment of PDN. We focused on spinal cord stimulators (SCS), peripheral nerve stimulators (PNS), transcutaneous electrical nerve stimulators (TENS), and scrambler therapy devices (ST) because they are often used for refractory neuropathic pain. STUDY DESIGN: Narrative Review. METHODS: A comprehensive and reproducible literature search was performed using PubMed with no search restrictions applied. The available Medical Subject Headings were used. Inclusion criteria included prospective studies, retrospective studies, case series, and case reports indexed from database inception to the search date (September 14, 2021). RESULTS: Seventeen studies met inclusion criteria, 10 of which were regarding SCS. Only 3 of the 10 were randomized controlled trials. We found no studies assessing contemporary PNS. Four studies assessed TENS, but the devices varied widely in voltages and waveforms. Two case reports described ST. LIMITATIONS: Potential selection bias due to the nature of a narrative review, although a reproducible search strategy was utilized. Several neuromodulation modalities have minimal published evidence available. CONCLUSIONS: The evidence for neuromodulation devices for the treatment of PDN mostly comprises open-label prospective trials or case reports. SCS has the most volume of evidence for efficacy. Studies regarding TENS show mixed results, possibly due to numerous device varieties. PNS and ST may hold promise based on their proposed mechanisms of action, but prospective controlled trials are needed.

Implantable Peripheral Nerve Stimulation for Peripheral Neuropathic Pain: A Systematic Review of Prospective Studies.

Peripheral nerve stimulation (PNS) has been utilized for over 50 years with accumulating evidence of efficacy in a variety of chronic pain conditions. The level and strength of evidence supporting the use of PNS for peripheral neuropathic pain remains unclear. The purpose of this review is to synthesize data from prospective studies on the efficacy of PNS for neuropathic pain as it pertains to pain intensity, neurological deficits/neuropathy (e.g., weakness, sensory deficits, gait/balance), and other secondary outcomes (quality of life, satisfaction, emotional functioning, and adverse events). In compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, this review identified articles from MEDLINE(R), EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus. Overall, per the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, pooled results demonstrate very low quality or low quality of evidence supporting modest to substantial improvement in pain and neurological function after PNS implantation for treatment of peripheral neuropathic pain. PNS for phantom limb pain was the only indication that had moderate level evidence. Future prospective and well-powered studies are warranted to assess the efficacy of PNS for peripheral neuropathic pain.

Scrambler Therapy for the Treatment of Multiple System Atrophy-Parkinsonian Subtype Pain: A Case Report.

The management of pain in patients with multiple system atrophy (MSA) is often inadequate, and treatments commonly result in adverse effects. A 63-year-old man with the parkinsonian subtype of MSA presented with bilateral neck, shoulder, upper extremity, lower extremity, and low back pain of 6 years' duration. His baseline pain was 5 of 10 with flares to 10 of 10. After 4 35-minute scrambler therapy (ST) treatments, his pain was reduced to 0 of 10. His pain relief after 4 ST sessions lasted for 6 weeks. No complications or adverse effects occurred. ST deserves further study for patients with atypical parkinsonism.

SATB2: A versatile transcriptional regulator of craniofacial and skeleton development, neurogenesis and tumorigenesis, and its applications in regenerative medicine.

SATB2 (special AT-rich sequence-binding protein 2) is a member of the special AT-rich binding protein family. As a transcription regulator, SATB2 mainly integrates higher-order chromatin organization. SATB2 expression appears to be tissue- and stage-specific, and is governed by several cellular signaling molecules and mediators. Expressed in branchial arches and osteoblast-lineage cells, SATB2 plays a significant role in craniofacial pattern and skeleton development. In addition to regulating osteogenic differentiation, SATB2 also displays versatile functions in neural development and cancer progression. As an osteoinductive factor, SATB2 holds great promise in improving bone regeneration toward bone defect repair. In this review, we have summarized our current understanding of the physiological and pathological functions of SATB2 in craniofacial and skeleton development, neurogenesis, tumorigenesis and regenerative medicine.

Chronic pain and infection: mechanisms, causes, conditions, treatments, and controversies.

Throughout human history, infection has been the leading cause of morbidity and mortality, with pain being one of the cardinal warning signs. However, in a substantial percentage of cases, pain can persist after resolution of acute illness, manifesting as neuropathic, nociplastic (eg, fibromyalgia, irritable bowel syndrome), or nociceptive pain. Mechanisms by which acute infectious pain becomes chronic are variable and can include immunological phenomena (eg, bystander activation, molecular mimicry), direct microbe invasion, central sensitization from physical or psychological triggers, and complications from treatment. Microbes resulting in a high incidence of chronic pain include bacteria such as the Borrelia species and Mycobacterium leprae, as well as viruses such as HIV, SARS-CoV-2 and herpeses. Emerging evidence also supports an infectious cause in a subset of patients with discogenic low back pain and inflammatory bowel disease. Although antimicrobial treatment might have a role in treating chronic pain states that involve active infectious inflammatory processes, their use in chronic pain conditions resulting from autoimmune mechanisms, central sensitization and irrevocable tissue (eg, arthropathy, vasculitis) or nerve injury, are likely to cause more harm than benefit. This review focuses on the relation between infection and chronic pain, with an emphasis on common viral and bacterial causes.

Mice Harboring a Non-Functional CILK1/ICK Allele Fail to Model the Epileptic Phenotype in Patients Carrying Variant CILK1/ICK.

CILK1 (ciliogenesis associated kinase 1)/ICK (intestinal cell kinase) is a highly conserved protein kinase that regulates primary cilia structure and function. CILK1 mutations cause a wide spectrum of human diseases collectively called ciliopathies. While several CILK1 heterozygous variants have been recently linked to juvenile myoclonic epilepsy (JME), it remains unclear whether these mutations cause seizures. Herein, we investigated whether mice harboring either a heterozygous null Cilk1 (Cilk1+/-) mutation or a heterozygous loss-of-function Cilk1 mutation (Cilk1R272Q/+) have epilepsy. We first evaluated the spontaneous seizure phenotype of Cilk1+/- and Cilk1R272Q/+ mice relative to wildtype littermates. We observed no electrographic differences among the three mouse genotypes during prolonged recordings. We also evaluated electrographic and behavioral responses of mice recovering from isoflurane anesthesia, an approach recently used to measure seizure-like activity. Again, we observed no electrographic or behavioral differences in control versus Cilk1+/- and Cilk1R272Q/+ mice upon isoflurane recovery. These results indicate that mice bearing a non-functional copy of Cilk1 fail to produce electrographic patterns resembling those of JME patients with a variant CILK1 copy. Our findings argue against CILK1 haploinsufficiency being the mechanism that links CILK1 variants to JME.

Applications of Biocompatible Scaffold Materials in Stem Cell-Based Cartilage Tissue Engineering.

Cartilage, especially articular cartilage, is a unique connective tissue consisting of chondrocytes and cartilage matrix that covers the surface of joints. It plays a critical role in maintaining joint durability and mobility by providing nearly frictionless articulation for mechanical load transmission between joints. Damage to the articular cartilage frequently results from sport-related injuries, systemic diseases, degeneration, trauma, or tumors. Failure to treat impaired cartilage may lead to osteoarthritis, affecting more than 25% of the adult population globally. Articular cartilage has a very low intrinsic self-repair capacity due to the limited proliferative ability of adult chondrocytes, lack of vascularization and innervation, slow matrix turnover, and low supply of progenitor cells. Furthermore, articular chondrocytes are encapsulated in low-nutrient, low-oxygen environment. While cartilage restoration techniques such as osteochondral transplantation, autologous chondrocyte implantation (ACI), and microfracture have been used to repair certain cartilage defects, the clinical outcomes are often mixed and undesirable. Cartilage tissue engineering (CTE) may hold promise to facilitate cartilage repair. Ideally, the prerequisites for successful CTE should include the use of effective chondrogenic factors, an ample supply of chondrogenic progenitors, and the employment of cell-friendly, biocompatible scaffold materials. Significant progress has been made on the above three fronts in past decade, which has been further facilitated by the advent of 3D bio-printing. In this review, we briefly discuss potential sources of chondrogenic progenitors. We then primarily focus on currently available chondrocyte-friendly scaffold materials, along with 3D bioprinting techniques, for their potential roles in effective CTE. It is hoped that this review will serve as a primer to bring cartilage biologists, synthetic chemists, biomechanical engineers, and 3D-bioprinting technologists together to expedite CTE process for eventual clinical applications.

Identification of a prognostic signature based on copy number variations (CNVs) and CNV-modulated gene expression in acute myeloid leukemia.

OBJECTIVES: Acute myeloid leukemia (AML) is caused by multiple genetic alterations in hematopoietic progenitors, and molecular genetic analyses have provided useful information for AML diagnosis and prognostication. This study aimed to integratively understand the prognostic value of specific copy number variation (CNV) patterns and CNV-modulated gene expression in AML. METHODS: We conducted integrative CNV profiling and gene expression analysis using data from the Therapeutically Applicable Research To Generate Effective Treatments (TARGET) and The Cancer Genome Atlas (TCGA) AML cohorts. CNV-related genes associated with survival were identified using the TARGET AML cohort and validated using the TCGA AML cohort. Genes whose CNV-modulated expression was associated with survival were also identified using the TARGET AML cohort and validated using the TCGA AML cohort, and patient bone marrow samples were then used to further validate the effects of CNV-modulated gene expression on survival. CNV and mRNA survival analyses were conducted using proportional hazards regression models (Cox regression) and the "survminer" and "survival" packages of the R Project for Statistical Computing. Genes belonging to the Kyoto Encyclopedia of Genes and Genomes (KEGG) cancer panel were extracted from KEGG cancer-related pathways. RESULTS: One hundred two CNV-related genes (located at 7q31-34, 16q24) associated with patient survival were identified using the TARGET cohort and validated with the TCGA AML cohort. Among these 102 validated genes, three miRNA genes (MIR29A, MIR183, and MIR335) were included in the KEGG cancer panel. Five genes (SEMA4D, CBFB, CHAF1B, SAE1, and DNMT1) whose expression was modulated by CNVs and significantly associated with clinical outcomes were identified, and the deletion of SEMA4D and CBFB was found to potentially exert protective effects against AML. The results of these five genes were also validated using patient marrow samples. Additionally, the distribution of CNVs affecting these five CNV-modulated genes was independent of the risk group (favorable-, intermediate-, and adverse-risk groups). CONCLUSIONS: Overall, this study identified 102 CNV-related genes associated with patient survival and identified five genes whose expression was modulated by CNVs and associated with patient survival. Our findings are crucial for the development of new modes of prognosis evaluation and targeted therapy for AML.

Targeted Program in an Academic Rheumatology Practice to Improve Compliance With Opioid Prescribing Guidelines for the Treatment of Chronic Pain.

OBJECTIVE: The Centers for Disease Control and Prevention (CDC) and many state governments have issued guidelines for opioid prescribing for the treatment of chronic noncancer-associated pain. We sought to decrease practice variation and increase compliance with these guidelines in a tertiary academic rheumatology practice by developing an interdisciplinary opioid working group and using electronic health record (EHR)-integrated data feedback. METHODS: Division leadership and providers established shared goals at interdisciplinary meetings involving rheumatology, pain medicine, nursing, and pharmacy. Interventions included educational sessions on opioid prescribing guidelines and the sharing of individual de-identified prescribing patterns. An opioid dashboard page within the EHR allowed every provider to see individualized and division-wide data that tracked process measures based on CDC and state-specific guidelines. Baseline data from June to August 2017 were compared with monthly data through December 2018. RESULTS: At baseline, 40% of patients had an active opioid agreement (a Pennsylvania guideline and a New Jersey law), 25% had a urine drug screen result within 12 months of their most recent opioid prescription, and 24% had a concurrent benzodiazepine prescription. After 16 months, these percentages improved to 88%, 66%, and 16%, respectively. The average number of opioid tablets prescribed per month decreased from 59,733 to 48,966 (-18%; P = 0.02). CONCLUSION: Shared goals developed through interdisciplinary input and readily accessible data feedback can markedly increase provider compliance with national and state-specific guidelines for opioid prescribing for the treatment of chronic noncancer-associated pain in rheumatology.
