Abstract Background and Aims Pain is one of the commonest symptoms in patients with chronic kidney disease (CKD), with a large proportion undertreated. Managing chronic pain in CKD patients is problematic due to the altered pharmacokinetic and pharmacodynamic related to the reduced renal clearance making it challenging for physicians to find appropriate pain management strategies. The aim of this systematic review was to estimate the overall prevalence of different types of analgesia in patients with CKD and investigate their safety. Method The population comprised of all adult patients with CKD defined as an estimated glomerular filtration rate (eGFR) less than 60mL/min/1.73m2 which included CKD-non dialysis (CKD-ND), kidney transplant recipients (KTR), patients undergoing dialysis and those receiving palliative care. Analgesics investigated included opioids, Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), gabapentinoids and acetaminophen. All studies reporting a prevalence of analgesic use and/or exploring the association between analgesic consumption and adverse outcomes were included. Medline, Embase, CENTRAL, CINAHL and the grey literature were searched up to December 2020. Random-effect meta-analyses were conducted using a Generalised Linear Mixed Model approach to estimate the overall prevalence of analgesics use in the CKD population, displayed in forest-plots. Evidence gathered from studies investigating the adverse outcomes related to analgesics consumption was synthesised in ‘harvest plots’. Results Sixty-three studies reporting a prevalence of analgesic use in patients with CKD were included. The overall prevalence of analgesic consumption was 42% (95% CI, 35-50%) in the general CKD population and 70% (95% CI, 62-68%) among those experiencing chronic pain. Seventeen studies reported a prevalence of opioid use with 36% (95% CI, 23-51%) of patients with CKD receiving at least one opioid prescription while 16% (95% CI, 11-22%) were on chronic opioid therapy. The chronic use of oxycodone, tramadol, propoxyphene, fentanyl and hydromorphone were 3.6%, 2.0%, 1.3%, 1.1% and 0.05% respectively. NSAIDs usage was estimated to 20% (95% CI, 15-25%) among patients with CKD (ibuprofen 4.6%, diclofenac 1.7%) and 8% (95% CI, 5-12%) took NSAIDs chronically, with a higher prevalence among dialysis patients (17%) compared with CKD-ND (7%) and KTR (5%) (p<0.01). Prevalence of gabapentin and pregabalin use was estimated at 10% and 3.5% respectively, on pooling of 3 studies. Finally, five studies yielded an overall prevalence of 24% for acetaminophen use. Twenty studies assessing the association between analgesic use and adverse outcomes were included (Figure 1). Five of them demonstrated an association between opioid use and increased mortality, in all CKD subgroups; and three out of four studies reported more hospitalizations in opioid-users.Four studies highlighted an increased risk of gastro-intestinal bleeding associated with NSAIDs consumption and three studies found a significant association between gabapentin use and neurologic adverse events. Conclusion Only 70% of CKD patients experiencing chronic pain received an analgesic, suggesting that pain remains a significant public health burden. Despite limited evidence, opioids, NSAIDs and gabapentinoids seem to be associated with major adverse events. Their use requires cautious prescription, consideration of optimal dosage, and the development of therapeutic patient education to promote risk awareness. More evidence is warranted to better understand the adverse outcomes associated with long-term analgesic consumption and provide safe pain management strategies for patient with CKD.

Background: Pain is common in patients with chronic kidney disease (CKD). Analgesics may be appropriate for some CKD patients. Objectives: To determine the prevalence of overall analgesic use and the use of different types of analgesics including acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), adjuvants, and opioids in patients with CKD. Design: Systematic review and meta-analysis. Setting: Interventional and observational studies presenting data from 2000 or later. Exclusion criteria included acute kidney injury or studies that limited the study population to a specific cause, symptom, and/or comorbidity. Patients: Adults with stage 3-5 CKD including dialysis patients and those managed conservatively without dialysis. Measurements: Data extracted included title, first author, design, country, year of data collection, publication year, mean age, stage of CKD, prevalence of analgesic use, and the types of analgesics prescribed. Methods: Databases searched included MEDLINE, CINAHL, EMBASE, and Cochrane Library. Two reviewers independently screened all titles and abstracts, assessed potentially relevant articles, and extracted data. We estimated pooled prevalence of analgesic use and the I2 statistic was computed to measure heterogeneity. Random-effects models were used to account for variations in study design and sample populations, and a double arcsine transformation of the prevalence variables was used to accommodate potential overweighting of studies with very large or very small prevalence measurements. Sensitivity analyses were performed to determine the magnitude of publication bias and assess possible sources of heterogeneity. Results: Forty studies were included in the analysis. The prevalence of overall analgesic use in the random-effects model was 50.8%. The prevalence of acetaminophen, NSAIDs, and adjuvant use was 27.5%, 17.2%, and 23.4%, respectively, while the prevalence of opioid use was 23.8%. Due to the possibility of publication bias, the actual prevalence of acetaminophen use in patients with advanced CKD may be substantially lower than this meta-analysis indicates. A trim-and-fill analysis decreased the pooled prevalence estimate of acetaminophen use to 5.4%. The prevalence rate for opioid use was highly influenced by 2 large US studies. When these were removed, the estimated prevalence decreased to 17.3%. Limitations: There was a lack of detailed information regarding the analgesic regimen (such as specific analgesics used within each class and inconsistent accounting for patients on multiple drugs and the use of over-the-counter analgesics such as acetaminophen and NSAIDs), patient characteristics, type of pain being treated, and the outcomes of treatment. Data on adjuvant use were very limited. These results, therefore, must be interpreted with caution. Conclusions: There was tremendous variability in the prescribing patterns of both nonopioid and opioid analgesics within and between countries suggesting widespread uncertainty about the optimal pharmacological approach to treating pain. Further research that incorporates robust reporting of analgesic regimens and links prescribing patterns to clinical outcomes is needed to guide optimal clinical practice.

Background: Chronic pain is a common and distressing symptom reported by patients with chronic kidney disease (CKD). Clinical practice and research in this area do not appear to be advancing sufficiently to address the issue of chronic pain management in patients with CKD. Objectives: To determine the prevalence and severity of chronic pain in patients with CKD. Design: Systematic review and meta-analysis. Setting: Interventional and observational studies presenting data from 2000 or later. Exclusion criteria included acute kidney injury or studies that limited the study population to a specific cause, symptom, and/or comorbidity. Patients: Adults with glomerular filtration rate (GFR) category 3 to 5 CKD including dialysis patients and those managed conservatively without dialysis. Measurements: Data extracted included title, first author, design, country, year of data collection, publication year, mean age, stage of CKD, prevalence of pain, and severity of pain. Methods: Databases searched included MEDLINE, CINAHL, EMBASE, and Cochrane Library, last searched on February 3, 2020. Two reviewers independently screened all titles and abstracts, assessed potentially relevant articles, and extracted data. We estimated pooled prevalence of overall chronic pain, musculoskeletal pain, bone/joint pain, muscle pain/soreness, and neuropathic pain and the I2 statistic was computed to measure heterogeneity. Random effects models were used to account for variations in study design and sample populations and a double arcsine transformation was used in the model calculations to account for potential overweighting of studies reporting either very high or very low prevalence measurements. Pain severity scores were calibrated to a score out of 10, to compare across studies. Weighted mean severity scores and 95% confidence intervals were reported. Results: Sixty-eight studies representing 16 558 patients from 26 countries were included. The mean prevalence of chronic pain in hemodialysis patients was 60.5%, and the mean prevalence of moderate or severe pain was 43.6%. Although limited, pain prevalence data for peritoneal dialysis patients (35.9%), those managed conservatively without dialysis (59.8%), those following withdrawal of dialysis (39.2%), and patients with earlier GFR category of CKD (61.2%) suggest similarly high prevalence rates. Limitations: Studies lacked a consistent approach to defining the chronicity and nature of pain. There was also variability in the measures used to determine pain severity, limiting the ability to compare findings across populations. Furthermore, most studies reported mean severity scores for the entire cohort, rather than reporting the prevalence (numerator and denominator) for each of the pain severity categories (mild, moderate, and severe). Mean severity scores for a population do not allow for “responder analyses” nor allow for an understanding of clinically relevant pain. Conclusions: Chronic pain is common and often severe across diverse CKD populations providing a strong imperative to establish chronic pain management as a clinical and research priority. Future research needs to move toward a better understanding of the determinants of chronic pain and to evaluating the effectiveness of pain management strategies with particular attention to the patient outcomes such as overall symptom burden, physical function, and quality of life. The current variability in the outcome measures used to assess pain limits the ability to pool data or make comparisons among studies, which will hinder future evaluations of the efficacy and effectiveness of treatments. Recommendations for measuring and reporting pain in future CKD studies are provided. Trial registration: PROSPERO Registration number CRD42020166965

AbstractBackground and aimsMultidomain strategies (i.e. two or more strategies) for managing chronic pain are recommended to avoid excessive use of opioids while producing the best outcomes possible. The aims of this systematic review were to: 1) determine if patient-reported pain management is consistent with the use of multidomain strategies; and 2) identify the role of opioids and non-steroidal anti-inflammatory drugs (NSAIDs) in patient-reported pain management.MethodsBibliographic databases, websites, and reference lists of included studies were searched to identify published articles reporting community-based surveys of pain self-management from January 1989 to June 2017 using controlled vocabulary (and synonyms): pain; self-care; self-management; self-treatment; and adult. Two independent reviewers screened studies and extracted data on subject demographics, pain characteristics, pain self-management strategies, and pain outcomes. Pain self-management strategies were organized according to our conceptual model. Included studies were assessed for risk of bias. Differences between the researchers were resolved by consensus.ResultsFrom the 3,235 unique records identified, 18 studies published between 2002 and 2017 from 10 countries were included. Twenty-two types of pharmacological strategies were identified (16 prescription, six non-prescription). NSAIDs (15 studies, range of use 10–72%) and opioids (12 studies, range of use 5–72%) were the most commonly reported prescription pharmacological strategies. Other prescription pharmacological strategies included analgesics, acetaminophen, anticonvulsants, antidepressants, anxiolytics, salicylates, β-blockers and calcium channel blockers, disease-modifying anti-rheumatic drugs and steroids, muscle relaxants, topical products, triptans, and others. Twenty-two types of non-pharmacological strategies were identified: four medical strategies (10 studies), 10 physical strategies (15 studies), four psychological strategies (12 studies), and four self-initiated strategies (15 studies). Medical strategies included consulting a medical practitioner, chiropractic, and surgery. Physical strategies included exercise, massage, hot and cold modalities, acupuncture, physical therapy, transcutaneous electrical nerve stimulation, activity modification or restriction, assistive devices, and altering body position/posture. Psychological strategies included relaxation, prayer or meditation, therapy, and rest/sleep. Self-initiated strategies included dietary or herbal supplements, dietary modifications, and complementary and alternative medicine. Overall, the number of strategies reported among the studies ranged from five to 28 (out of 44 identified strategies). Limited data on pain outcomes was reported in 15 studies, and included satisfaction with pain management strategies, pain interference on daily activities, adverse events, lost work or restricted activity days, emergency department visits, and disabilities.ConclusionsA wide variety and large number of pharmacological and non-pharmacological strategies to manage chronic pain were reported, consistent with the use of multidomain strategies. High levels of use of both NSAIDs and opioids also were reported.ImplicationsComprehensive review and consultation with patients about their pain management strategies is likely needed for optimal outcomes. Additional research is needed to determine: how many, when, and why multidomain strategies are used; the relationship between opioid use, multidomain management strategies, and level of pain; how multidomain strategies relate to outcomes; and if adding strategies to a pain management plan increases the risk of adverse events or interactions, and increases an individuals pain management burden.
