Interventional Clinical Trials on Diabetic Peripheral Neuropathy: A Retrospective Analysis.
Journal of pain research
AIMS/INTRODUCTION:Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes. At present, there is no comprehensive summary of the clinical trials related to DPN. In this article, we summarized the basic characteristics of the interventional clinical trials pertaining to DPN to determine the current status of research in this field and the existing issues. MATERIALS AND METHODS:We searched the World Health Organization International Clinical Trial Registration Platform (ICTRP), PubMed and Web of Science for clinical trials from 2005 to April 2021 and extracted 149 registered and 459 published clinical trials on DPN. We summarized the characteristics of the clinical trials, including the source registration, recruitment status, stage, age group, allocation method, intervention, end point classification, funding source, and treatment. RESULTS:After excluding noninterventional and nontreatment trials, 149 registered clinical trials out of 292 records from 12 registration centers and 459 published articles were included in this study. Among the registered trials, 43% had been completed, and 34.4% had been published in peer-reviewed journals. Among these trials, more than half used random allocation and blinded placebo-controlled methodologies. A total of 40.3% of the trials were multicenter studies, 63.8% of the treatments were drug therapies, and the endpoint classifications of 49% were efficacy and safety. Of the 459 published interventional clinical trials on DPN, 69.7% of the trials used drug treatments; more than half were randomized, double-blind, placebo-controlled clinical trials; 94.1% had positive outcomes; 46.4% had a target size of 50; and 22.9% were multicenter. CONCLUSION:This paper systematically summarizes the current status of interventional trials on DPN registered in the ICTRP and published clinical trials and provides a reference for the development of high-quality intervention strategies for DPN in the future.

A Systematic Review and Meta-Analysis of Intraperitoneal Bupivacaine in Laparoscopic Gynecologic Surgery.
Journal of pain research
OBJECTIVE:We set out to evaluate whether the instillation of bupivacaine versus a saline solution into the peritoneal cavity at time of laparoscopic gynecologic surgery will reduce postoperative pain and postoperative opioid consumption. DATA SOURCES:We searched six databases: Web of Science, SCOPUS, Cochrane CENTRAL, ClinicalTrials.Gov, MEDLINE and PubMed. Our search strategy had no restriction on time or languages and included all studies that met our search algorithm up to March of 2021. METHODS OF STUDY SELECTION:We included only randomized trials that met our search strategy for the outcomes of 1) pain intensity 24 hours after surgery, 2) pain intensity 6 hours after surgery, and 3) length of hospital stay. TABULATION INTEGRATION AND RESULTS:We analyzed continuous data using mean difference (MD) with relative 95% confidence interval (CI). We included 8 randomized clinical trials. We found that intraperitoneal bupivacaine showed significant difference from the saline group regarding pain intensity 24 hours after surgery (MD= -0.73 [-1.10, -0.36]) (P = 0.01) and pain intensity 6 hours after surgery (MD= -1.12 [-2.22, -0.02]) (P = 0.05). Overall, patients allocated to the placebo group seemed to need other analgesics earlier than patients allocated to the bupivacaine group (MD=145.08 [51.37, 238.79] (P = 0.02)). There was no significant difference regarding the length of hospital stay (MD= -0.44 [-1.44, 0.56]) (P = 0.39). CONCLUSION:Bupivacaine significantly reduced the visual analog pain score for pain compared with that of the placebo at 6 and 24 hours postoperatively. There was no significant difference in hospital stay. PROSPERO REGISTRATION:CRD42021254268.

Systematic Review and Meta-Analysis of Acupuncture for Pain Management in Women Undergoing Transvaginal Oocyte Retrieval.
Journal of pain research
OBJECTIVE:To obtain evidence-based conclusions about the effect of acupuncture on pain relief in women undergoing oocyte retrieval, the results of randomized controlled trials (RCTs) that met the criteria were assessed on the Pain Assessment Scale and pregnancy indicators. SEARCH METHODS:References were retrieved in MEDLINE, EMBASE, CNKI database, CBM database, VIP database, and Wanfang database from inception to June 26, 2021. Unpublished ongoing trials were searched in the Clinical Trials Registries. This review included RCTs that investigated the acupuncture analgesic effects during oocyte retrieval in women undergoing in vitro fertilization. RESULTS:Fourteen RCTs (2503 women in total) with six types of comparisons were finally included. The quality of concluding evidence was generally low or very low. Performance bias and outcome assessment bias was the main risk of bias of the included studies. Acupuncture combined with conscious sedation and analgesia (CSA) was associated with less intraoperative (SMD=-1.03; 95% CI: -1.71 to -0.36) and postoperative (SMD = -1.11; 95% CI: -1.51 to -0.71) pain compared to receive CSA alone in oocyte retrieval. Acupuncture with non-steroidal anti-inflammatory drugs (NSAIDs) was more effective than using NSAIDs alone for postoperative analgesia (MD = -1.76; 95% CI: -2.08 to -1.44). CONCLUSION:Acupuncture complex analgesic therapy is more effective than utilizing CSA or NSAIDs alone. Furthermore, there is no significant consensus on whether there is an analgesic effect of applying acupuncture alone during oocyte retrievals, which needs further research. The overall results should be interpreted with caution due to the high risk of bias/low-GRADE scores among these studies. PROTOCOL AND REGISTRATION:PROSPERO registration number: CRD42020170095.

Neuropathic Pain Creates Systemic Ultrastructural Changes in the Nervous System Corrected by Electroacupuncture but Not by Pregabalin.
Journal of pain research
PURPOSE:It is unclear whether neuropathological structural changes in the peripheral nervous system and central nervous system can occur in the spared nerve injury model. In this study, we investigated the pathological changes in the nervous system in a model of neuropathic pain as well as the effects of electroacupuncture (EA) and pregabalin (PGB) administration as regards pain relief and tissue repair. PATIENTS AND METHODS:Forty adult male SD rats were equally and randomly divided into 4 groups: spared nerve injury group (SNI, n = 10), SNI with electroacupuncture group (EA, n = 10), SNI with pregabalin group (PGB, n =10) and sham-operated group (Sham, n=10). EA and PGB were given from postoperative day (POD) 14 to 36. EA (2 Hz and 100 Hz alternating frequencies, intensities ranging from 1-1.5-2 mA) was applied to the left "zusanli" (ST36) and "Yanglingquan" (GB34) acupoints for 30 minutes. The mechanical withdrawal thresholds (MWTs) were tested with von Frey filaments. Moreover, the organizational and structural alterations of the bilateral prefrontal cortex, hippocampus, sciatic nerves and the thoracic, lumbar spinal cords and dorsal root ganglions (DRGs) were examined via light and electron microscopy. RESULTS:MWTs of left hind paw demonstrated a remarkable decrease in the SNI model (P < 0.05). In the SNI model, ultrastructural changes including demyelination and damaged neurons were observed at all levels of the peripheral nervous system (PNS) and central nervous system (CNS). In addition, EA improved MWTs and restored the normal structure of neurons. However, the effect was not found in the PGB treatment group. CONCLUSION:Chronic pain can induce extensive damage to the central and peripheral nervous systems. Meanwhile, EA and PGB can both alleviate chronic pain syndromes in rats, but EA also restores the normal cellular structures, while PGB is associated with no improvement.

Pain Relief Salvage with a Novel Minimally Invasive Posterior Sacroiliac Joint Fusion Device in Patients with Previously Implanted Pain Devices and Therapies.
Journal of pain research
BACKGROUND:Sacroiliac joint (SIJ) pain is a common cause of low back pain, a problem experienced by two-thirds of adults in the United States population. Traditionally, the management of persistent SIJ-related pain has involved conservative therapies (physical therapy, topical medications, oral anti-inflammatory medications), interventional therapies (SIJ steroid injections or ablation), and surgery (SIJ fusion; open and lateral approach). Recent advancements in technology have paved the way for SIJ fusion via a posterior approach, which aims to minimize complications and enhance recovery. OBJECTIVE:The purpose of this study is to introduce the concept of the posterior approach to SIJ fusion as a feasible adjunct and salvage technique for patients with inadequate pain relief from other minimally invasive surgical procedures, and to validate its efficacy through a retrospective multicenter data analysis. DESIGN:Multicenter retrospective observational study. METHODS:Patients with refractory SIJ pain were treated by interventional pain physicians at one of the eight different pain management centers. All patients underwent posterior SIJ fusion via the LinQ sacroiliac fusion procedure. Demographical data were collected, in addition to patient-reported pain relief. RESULTS:A total of 111 patients were included in the study and underwent posterior SIJ fusion for refractory SIJ-related pain following the use of spinal cord stimulation (SCS), interspinous spacer (ISS), intrathecal drug delivery (IDDS), and/or minimally invasive lumbar decompression (MILD). Overall, the mean patient reported pain relief following posterior SIJ fusion was 67.6%. In patients with a history of failed back surgery syndrome, the mean patient reported pain relief was 76.5%. CONCLUSION:In this retrospective case series of patients with continued intolerable pain following SCS, ISS, IDDS, or MILD, a novel posterior SIJ fusion device provided significant pain relief in a salvage manner. These early results suggest that this intervention may be a therapeutic option to consider in these patients.

Journal of pain research
Radiofrequency neurotomy (RFN), also known as radiofrequency ablation (RFA), is a common interventional procedure used to treat pain from an innervated structure. RFN has historically been used to treat chronic facet-joint mediated pain. The use of RFN has more recently expanded beyond facet-joint mediated pain to peripherally innervated targets. In addition, there has also been the emergence of different radiofrequency modalities, including pulsed and cooled RFN. The use of RFN has been particularly important where conservative and/or surgical measures have failed to provide pain relief. With the emergence of this therapeutic option and its novel applications, the American Society of Pain and Neuroscience (ASPN) identified the need for formal evidence-based guidance. The authors formed a multidisciplinary work group tasked to examine the latest evidence-based medicine for the various applications of RFN, including cervical, thoracic, lumbar spine; posterior sacroiliac joint pain; hip and knee joints; and occipital neuralgia. Best practice guidelines, evidence and consensus grading were provided for each anatomical target.

Efficacy of Radiofrequency Neurotomy in Chronic Low Back Pain: A Systematic Review and Meta-Analysis.
Journal of pain research
PURPOSE:The objective of the systematic review and meta-analysis is to evaluate the efficacy of radiofrequency neurotomy as a therapeutic lumbar facet joint intervention. PATIENTS AND METHODS:Utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, a systematic review and meta-analysis was performed. A comprehensive literature search of multiple data sources from 1966 to September 2020 including manual searches of bibliography of known review articles was performed. The inclusion criteria were based on the selection of patients with chronic low back pain with diagnosis confirmed based on controlled diagnostic blocks and with the publication of at least 6 months of results of appropriate outcome parameters. Quality assessment of the trials was performed with Cochrane review criteria and interventional pain management techniques-quality appraisal of reliability and risk of bias assessment (IPM-QRB). The level of evidence of effectiveness is classified at five levels ranging from Level I to Level V. The primary outcome measure was a significant reduction in pain, eg, short term (up to 6 months) and long term (more than 6 months). The secondary outcome measure was an improvement in functional status. RESULTS:A total of 12 randomized controlled trials (RCTs) met the inclusion criteria for evaluating the efficacy of lumbar radiofrequency neurotomy. Radiofrequency neurotomy showed Level II evidence for efficacy for both the short term and long term. CONCLUSION:This systematic review of the assessment of the efficacy of radiofrequency neurotomy in managing chronic low back pain was based on the inclusion of 12 RCTs with a diagnostic block and at least 6 months of follow-up results that showed Level II evidence for both short-term and long-term improvement.

Successful Diagnosis of Sacroiliac Joint Dysfunction.
Journal of pain research
BACKGROUND:Sacroiliac joint (SIJ) pain is one of the most common causes of low back pain, accounting for 15 to 30% of all cases. Although SIJ dysfunction accounts for a large portion of chronic low back pain prevalence, it is often overlooked or under diagnosed and subsequently under treated. The purpose of this review was to establish a best practices model to effectively diagnose SIJ pain through detailed history, physical exam, review of imaging, and diagnostic block. METHODS:A literature search was performed on the diagnosis of sacroiliac joint pain and sacroiliac joint dysfunction. The authors proposed diagnostic recommendations based upon the available literature and a detailed understanding of diagnosing SIJ pain. RESULTS:The practitioner must focus on the history, location of pain, observed gait pattern, and perform key points of the physical exam including sacroiliac provocative maneuvers. If the patient exhibits at least three provocative maneuvers then the SIJ may be considered as a possible source of pain. Additionally, a thorough review of the imaging should be performed to rule out other etiologies of low back pain. In the absence of any pathognomonic tests or examination findings, diagnostic SIJ blocks have evolved as the diagnostic standard. CONCLUSION:The diagnosis of SIJ pain is a multifaceted process that involves a careful assessment including differentiating other pain generators in the region. This involves careful history taking, appropriate physical examination including provocative maneuvers and diagnostic injections. Once the diagnosis is confirmed, long-term solutions may be considered, including recent advances in sacral lateral branch denervation and sacroiliac joint fusion.

A Retrospective Study on Chronic Pelvic Pain Treated with Traditional Chinese Medicine Combined Therapy: 179 Cases (2016-2018).
Journal of pain research
PURPOSE:This study aims to evaluate clinical efficiency and side effects of combined therapy of traditional Chinese medicine in female treating chronic pelvic pain. METHODS:A retrospective study was conducted by analyzing 179 patients with chronic pelvic pain. They were divided into the 3-course group and the 1-course group. Patients in the 3-course group received combined therapy of traditional Chinese medicine 10 days per menstrual cycle for three months, while the 1-course group received the same combined therapy for only one menstrual cycle. VAS scores of five kinds of pain were compared between the two groups. Meanwhile, SF-36 scores, menstruation, leucorrhea and major accompanying symptoms were analyzed. To assess side effects of the combined therapy, safety indices were recorded before and after treatment as well. RESULTS:VAS scores of patients in the 3-course group after treatment were significantly lower than that before the treatment. Total scores of SF-36 were significantly improved after the treatment, and persistently improved even after the discontinuation of the treatment. The menstrual and leucorrhea condition improved as well after the treatment. In addition, among the concomitant symptoms, insomnia, loss of appetite, mental fatigue symptoms were significantly improved after the treatment. More importantly, significances were observed in the improvement of most VAS scores between patients who underwent a 1-course treatment and patients with a 3-course treatment. Meanwhile, no significant change was observed in safety indices before and after treatment. Possible adverse events related to the treatment plan for all enrolled patients included mild skin rash in 16 patients, stomachache in 3 patients after taking medicine on an empty stomach, and oral ulcer in 1 patient. CONCLUSION:Combined therapy of traditional Chinese medicine alleviated symptoms of chronic pelvic pain, soothed the accompanying symptoms, and hence helped to improve the life quality of women.

Understanding the Psychological, Physiological, and Genetic Factors Affecting Precision Pain Medicine: A Narrative Review.
Journal of pain research
PURPOSE:Precision pain medicine focuses on employing methods to assess each patient individually, identify their risk profile for disproportionate pain and/or the development of chronic pain, and optimize therapeutic strategies to target specific pathological processes underlying chronic pain. This review aims to provide a concise summary of the current body of knowledge regarding psychological, physiological, and genetic determinants of chronic pain related to precision pain medicine. METHODS:Following the Scale for the Assessment of Narrative Review Articles (SANRA) criteria, we employed PubMed/Medline to identify relevant articles using primary database search terms to query articles such as: precision medicine, non-modifiable factors, pain, anesthesiology, quantitative sensory testing, genetics, pain medicine, and psychological. RESULTS:Precision pain medicine provides an opportunity to identify populations at risk, develop personalized treatment strategies, and reduce side effects and cost through elimination of ineffective treatment strategies. As in other complex chronic health conditions, there are two broad categories that contribute to chronic pain risk: modifiable and non-modifiable patient factors. This review focuses on three primary determinants of health, representing both modifiable and non-modifiable factors, that may contribute to a patient's profile for risk of developing pain and most effective management strategies: psychological, physiological, and genetic factors. CONCLUSION:Consideration of these three domains is already being integrated into patient care in other specialties, but by understanding the role they play in development and maintenance of chronic pain, we can begin to implement both precision and personalized treatment regimens.

Store-Operated Calcium Channels Contribute to Remifentanil-Induced Postoperative Hyperalgesia via Phosphorylation of CaMKIIα in Rats.
Journal of pain research
PURPOSE:The mechanisms of remifentanil-induced postoperative hyperalgesia (RIPH) remain unclear. Store-operated calcium channels (SOCCs) are mainly comprised of stromal interaction molecules 1 (STIM1) and pore-forming subunits (Orai1). They were found to take a pivotal part in Ca-dependent procedures and involved in the development of central sensitization and pain. Ca/calmodulin-dependent protein kinase IIα (CaMKIIα), regulated by Ca/calmodulin complex, has been shown to have a crucial role in RIPH. This study aims to determine whether SOCCs contribute to RIPH via activating CaMKIIα. MATERIALS AND METHODS:Intra-operative infusion of remifentanil (1.0 µg kg min, 60 min) was used to establish a RIPH rat model. The SOCCs blocker (YM-58483) was applied intrathecally to confirm the results. Animal behavioral tests including paw withdrawal thermal latency (PWTL) and paw withdrawal mechanical threshold (PWMT) were performed at -24, 2, 6, 24, 48 h after incision and remifentanil treatments. The protein expression of STIM1, Orai1, CaMKIIα, and p-CaMKIIα was assayed with Western blot, and the number of STIM1 and Orai1 positive cells was shown by immunofluorescence. RESULTS:Remifentanil administration significantly induced postoperative mechanical and thermal hyperalgesia, as well as increased STIM1 and Orai1 protein expression in the spinal dorsal horn. Furthermore, the intrathecal administration of YM-58483 effectively alleviated remifentanil-induced postoperative mechanical and thermal hyperalgesia according to the behavioral tests. In addition, YM-58483 suppressed the phosphorylation of CaMKIIα but had no effect on the expression of STIM1 and Orai1. CONCLUSION:Our study demonstrated that SOCCs are involved in RIPH. The over-expressed STIM1 and Orai1 in the spinal cord contribute to RIPH via mediating the phosphorylation of CaMKIIα. Blockade of SOCCs may provide an effective therapeutic approach for RIPH.

The Central Response of Electroacupuncture on Trigeminal Neuralgia Based on Resting-State Functional Magnetic Resonance Imaging: A Protocol for a Pre-Experimental, Single-Centre, Randomized, Controlled Trial.
Journal of pain research
OBJECTIVE:To verify the efficacy of electroacupuncture (EA) on classical trigeminal neuralgia (CTN), and to observe the brain functional status of patients with CTN and the intervention effects of EA on brain function by resting-state functional magnetic resonance imaging (rs-fMRI). METHODS AND ANALYSIS:Thirty CTN patients will be randomly divided into EA combined with carbamazepine group and carbamazepine group in 2:1 ratio by using a random number table. Patients in EA combined with carbamazepine will receive EA treatment and carbamazepine for four weeks. The carbamazepine group will only receive carbamazepine treatment. VAS (visual analogue scale), HAMA (Hamilton Anxiety Scale), HAMD (Hamilton Depression Scale) and SF-36 (short form 36 health survey) will be performed before, after four-week treatments and at three-month follow-up in CTN patients. Six CTN patients will be randomly selected from EA combined with carbamazepine group and carbamazepine group, respectively, before treatment, and twelve paired healthy participants will be recruited at the same time. The twelve CTN patients will be scanned by rs-fMRI before and after treatment, and the healthy participants will be scanned by rs-fMRI only at baseline. Regional homogeneity (ReHo) and amplitude of low-frequency fluctuation (ALFF) analysis will be carried out to compare the dysfunctional brain regions between CTN patients and healthy participants, as well as the differences between two groups of patients with CTN after treatment. TRIAL REGISTRATION:ChiCTR-1900027873.

Denying the Truth Does Not Change the Facts: A Systematic Analysis of Pseudoscientific Denial of Complex Regional Pain Syndrome.
Journal of pain research
PURPOSE:Several articles have claimed that complex regional pain syndrome (CRPS) does not exist. Although a minority view, it is important to understand the arguments presented in these articles. We conducted a systematic literature search to evaluate the methodological quality of articles that claim CRPS does not exist. We then examined and refuted the arguments supporting this claim using up-to-date scientific literature on CRPS. METHODS:A systematic search was conducted in MEDLINE, EMBASE and Cochrane CENTRAL databases. Inclusion criteria for articles were (a) a claim made that CRPS does not exist or that CRPS is not a distinct diagnostic entity and (b) support of these claims with subsequent argument(s). The methodological quality of articles was assessed if possible. RESULTS:Nine articles were included for analysis: 4 narrative reviews, 2 personal views, 1 letter, 1 editorial and 1 case report. Seven points of controversy were used in these articles to argue that CRPS does not exist: 1) disagreement with the label "CRPS"; 2) the "unclear" pathophysiology; 3) the validity of the diagnostic criteria; 4) CRPS as a normal consequence of immobilization; 5) the role of psychological factors; 6) other identifiable causes for CRPS symptoms; and 7) the methodological quality of CRPS research. CONCLUSION:The level of evidence for the claim that CRPS does not exist is very weak. Published accounts concluding that CRPS does not exist, in the absence of primary evidence to underpin them, can harm patients by encouraging dismissal of patients' signs and symptoms.

Direct and Indirect Relationships Between Physical Activity, Fitness Level, Kinesiophobia, and Health-Related Quality of Life in Patients with Rheumatic and Musculoskeletal Diseases: A Network Analysis.
Journal of pain research
INTRODUCTION:Using a network analysis, the present study investigated the extent to which physical activity (PA), objective fitness level, kinesiophobia, and health-related quality of life (HRQoL) interact in patients with rheumatic and musculoskeletal diseases. The objectives were twofold: 1) to clarify the direct and indirect relationships between these variables while controlling for the shared variance between them, and 2) to establish a potential ranking of influence among them. METHODS:This cross-sectional design study involved patients recruited from a rheumatology unit. One hundred and twenty patients completed self-reported measures of PA, the Tampa scale of kinesiophobia and the 36-item Short-Form Health Survey, and ninety-seven of those patients performed the six-minute walking test and the thirty-second sit-to-stand test. Network analyses were conducted using bootnet and qgraph packages. RESULTS:Weekly time spent on PA, as well as physical fitness measures, were directly linked to kinesiophobia and the HRQoL physical dimension, but indirectly linked to HRQoL mental dimension through the mediation of kinesiophobia. Specifically, weekly PA time had direct relationships to physical functioning, vitality, and role limitations due to physical and emotional problems. Fitness measures had direct relationships with physical functioning, bodily pain, and mental health. The analyses did not clearly highlight one variable as the most influential in the network. DISCUSSION:The study highlights the complexities of direct and indirect biopsychosocial relationships that are at the core of patients' daily functioning. Measurement of PA, use of a longitudinal design, and interventions are discussed.

Trigeminal Neuralgia: Current Approaches and Emerging Interventions.
Journal of pain research
Trigeminal neuralgia (TN) has been described in the literature as one of the most debilitating presentations of orofacial pain. This review summarizes over 150 years of collective clinical experience in the medical and surgical treatment of TN. Fundamentally, TN remains a clinical diagnosis that must be distinguished from other types of trigeminal neuropathic pain and/or facial pain associated with other neuralgias or headache syndromes. What is increasingly clear is that there is no catch-all medical or surgical intervention that is effective for all patients with trigeminal neuralgia, likely reflective of the fact that TN is likely a heterogenous group of disorders that jointly manifests in facial pain. The first-line treatment for TN remains anticonvulsant medical therapy. Patients who fail this have a range of surgical options available to them. In general, microvascular decompression is a safe and effective procedure with immediate and durable outcomes. Patients who are unable to tolerate general anesthesia or whose medical comorbidities preclude a suboccipital craniectomy may benefit from percutaneous methodologies including glycerol or radiofrequency ablation, or both. For patients with bleeding diathesis due to blood thinning medications who are ineligible for invasive procedures, or for those who are unwilling to undergo open surgical procedures, radiosurgery may be an excellent option-provided the patient understands that maximum pain relief will take on the order of months to achieve. Finally, peripheral neurectomies continue to provide an inexpensive and resource-sparing alternative to pain relief for patients in locations with limited economic and medical resources. Ultimately, elucidation of the molecular mechanisms underlying trigeminal neuralgia will pave the way for novel, more effective and less invasive therapies.

Nurses' Perceived Barriers to and Facilitators of Pain Assessment and Management in Critical Care Patients: A Systematic Review.
Journal of pain research
AIM:This review aims to examine nurses' perceived barriers to and facilitators of pain assessment and management in adult critical care patients. BACKGROUND:Pain is one of the worst memories among critically ill patients. However, pain among those patients is still undertreated due to several barriers that impede effective management. Therefore, addressing the perceived barriers and facilitators to pain assessment management among critical care nurses is crucial. METHODS:A systematic search of pain assessment and management in critical care patient-relevant literature from four databases was done, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS:The barriers and facilitators were categorized into four groups: nurse-related, patient-related, physician-related, and system-related. The most frequently reported barriers in this study included nurses' lack of knowledge regarding the use of pain assessment tools, patients' inability to communicate, physicians' prescription of analgesics being independent of pain scores evaluation, and absence of standardized guidelines and protocols for pain evaluation and control. For the facilitators, the most reported ones include ongoing education and professional training related to pain assessment and management, patients' ability to self-report pain, effective collaboration between physicians and nurses, and productive discussion of patients' pain scores during nurse-to-nurse handovers. CONCLUSION:Various barriers and facilitators to pain assessment and management were identified and examined in this review. However, future research is still needed to further investigate these barriers and facilitators and examine any other potential associated factors among critical care nurses. RELEVANCE TO CLINICAL PRACTICE:The findings of our study could help hospital managers in developing continuous education and staff development training programs on assessing and managing pain for critical care patients. Also, our findings could be used to develop an evidence-based standard pain management protocol tailored to effectively assess and promptly treat pain in critical care patients.

Impact of Cannabis Use on Least Pain Scores Among African American and White Patients with Cancer Pain: A Moderation Analysis.
Journal of pain research
INTRODUCTION:Based on many published reports, African American patients with cancer experience higher pain severity scores and lower pain relief than White patients. This disparity results from undertreatment of pain and is compounded by low adherence to prescribed non-opioid and opioid analgesics among African American patients with cancer. While nearly one in four patients use cannabis to manage cancer-related symptoms, less is known about how cannabis use influences pain relief in this patient population. METHODS:This study is based on preliminary data from an ongoing study of longitudinal outcomes of opioid therapy among African American and White patients with cancer. Linear mixed-effects models were utilized to assess the interaction of race and cannabis use on pain relief using "least pain" item scores from the Brief Pain Inventory (BPI) averaged across three time points. Models were adjusted for sociodemographic and clinical variables. RESULTS:This analysis included 136 patients (49 African American, 87 White). Overall, 30.1% of the sample reported cannabis use for cancer pain. The mean "least pain" score on BPI was 3.3 (SD=2.42) on a scale of 0-10. African American patients had a mean "least pain" score 1.32±0.48 units higher (indicating lower pain relief) than White patients (=0.006). Cannabis use did not have a significant main effect (=0.28). However, cannabis use was a significant moderator of the relationship between race and "least pain" (=0.03). In the absence of cannabis use, African Americans reported higher "least pain" scores compared to Whites (mean difference=1.631±0.5, =0.001). However, this disparity was no longer observed in African American patients reporting cannabis use (mean "least pain" difference=0.587±0.59, =0.32). CONCLUSION:These findings point to the possible role of cannabis in cancer pain management and its potential to reduce racial disparities. These findings are preliminary and further research into the role of cannabis in cancer pain outcomes is needed.
