BMJ Open 2024; 14:e071417. [PMID: 38171624 PMCID: PMC10773328 DOI: 10.1136/bmjopen-2022-071417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Accepted: 12/07/2023] [Indexed: 01/05/2024] Open
Abstract
OBJECTIVE This research aimed to assess the levels of cognitive function and its contributing factors among individuals experiencing cancer pain (CP) in mainland China. DESIGN A descriptive, cross-sectional study. SETTING The investigation was undertaken within three tertiary oncology hospitals. PARTICIPANTS We included 220 hospitalised individuals who reported experiencing cancer-related pain and consented to complete the research questionnaires. OUTCOME MEASURES The collected data encompassed sociodemographic and clinical variables, augmented by results from validated questionnaires. Cognitive impairment (CI) was evaluated using the Functional Assessment of Cancer Therapy-Cognitive (FACT-Cog) scale, with scores ranging from 0 to 148. Sleep quality, depression and anxiety were assessed through the Pittsburgh Sleep Quality Index, the Patient Health Questionnaire-9 and the Generalised Anxiety Disorder-7, respectively. A binary logistic regression model was used to identify factors associated with CI in individuals with CP. RESULTS Of the 225 individuals approached, 220 (97.8%) participated in the study. The mean FACT-Cog score for those with CP was 101.29 (SD=25.24; range=25-148). The prevalence of CI among these individuals was 35.90%. Sleep quality was rated below medium in 45% of participants with CP. More than moderate pain was reported by 28.2%, with 64.6% experiencing depression and 38.6% experiencing anxiety. Increased odds of developing CI were observed in those with CP (OR 1.422, 95% CI 1.129 to 1.841), depression (OR 1.119, 95% CI 1.029 to 1.2117), anxiety (OR 1.107, 95% CI 1.005 to 1.220), advancing age (OR 1.042, 95% CI 1.013 to 1.073), poor sleep quality (OR 1.126, 95% CI 1.013 to 1.252) and a history of smoking (OR 3.811, 95% CI 1.668 to 8.707). CONCLUSIONS CI associated with CP is notably prevalent in China. Those older, with a smoking history, inadequate sleep, more severe pain, depression and anxiety, have a heightened risk of CI. Consequently, interventions need to be personalised, addressing these key determinants.

Cannabis for medical use versus opioids for chronic non-cancer pain: a systematic review and network meta-analysis of randomised clinical trials. BMJ Open 2024; 14:e068182. [PMID: 38171632 PMCID: PMC10773353 DOI: 10.1136/bmjopen-2022-068182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Accepted: 11/27/2023] [Indexed: 01/05/2024] Open
Abstract
OBJECTIVE The objective of this study is to evaluate the comparative benefits and harms of opioids and cannabis for medical use for chronic non-cancer pain. DESIGN Systematic review and network meta-analysis. DATA SOURCES EMBASE, MEDLINE, CINAHL, AMED, PsycINFO, PubMed, Web of Science, Cannabis-Med, Epistemonikos and the Cochrane Library (CENTRAL) from inception to March 2021. STUDY SELECTION Randomised trials comparing any type of cannabis for medical use or opioids, against each other or placebo, with patient follow-up ≥4 weeks. DATA EXTRACTION AND SYNTHESIS Paired reviewers independently extracted data. We used Bayesian random-effects network meta-analyses to summarise the evidence and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach to evaluate the certainty of evidence and communicate our findings. RESULTS Ninety trials involving 22 028 patients were eligible for review, among which the length of follow-up ranged from 28 to 180 days. Moderate certainty evidence showed that opioids provide small improvements in pain, physical functioning and sleep quality versus placebo; low to moderate certainty evidence supported similar effects for cannabis versus placebo. Neither was more effective than placebo for role, social or emotional functioning (all high to moderate certainty evidence). Moderate certainty evidence showed there is probably little to no difference between cannabis for medical use and opioids for physical functioning (weighted mean difference (WMD) 0.47 on the 100-point 36-item Short Form Survey physical component summary score, 95% credible interval (CrI) -1.97 to 2.99), and cannabis resulted in fewer discontinuations due to adverse events versus opioids (OR 0.55, 95% CrI 0.36 to 0.83). Low certainty evidence suggested little to no difference between cannabis and opioids for pain relief (WMD 0.23 cm on a 10 cm Visual Analogue Scale (VAS), 95% CrI -0.06 to 0.53) or sleep quality (WMD 0.49 mm on a 100 mm VAS, 95% CrI -4.72 to 5.59). CONCLUSIONS Cannabis for medical use may be similarly effective and result in fewer discontinuations than opioids for chronic non-cancer pain. PROSPERO REGISTRATION NUMBER CRD42020185184.

Meeting high-risk patient pain care needs through intensive primary care: a secondary analysis. BMJ Open 2024; 14:e080748. [PMID: 38167288 PMCID: PMC10773401 DOI: 10.1136/bmjopen-2023-080748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 12/01/2023] [Indexed: 01/05/2024] Open
Abstract
OBJECTIVE Chronic pain disproportionately affects medically and psychosocially complex patients, many of whom are at high risk of hospitalisation. Pain prevalence among high-risk patients, however, is unknown, and pain is seldom a focus for improving high-risk patient outcomes. Our objective is to (1) evaluate pain frequency in a high-risk patient population and (2) identify intensive management (IM) programme features that patients and providers perceive as important for promoting patient-centred pain care within primary care (PC)-based IM. DESIGN Secondary observational analysis of quantitative and qualitative evaluation data from a multisite randomised PC-based IM programme for high-risk patients. SETTING Five integrated local Veterans Affairs (VA) healthcare systems within distinct VA administrative regions. PARTICIPANTS Staff and high-risk PC patients in the VA. INTERVENTION A multisite randomised PC-based IM programme for high-risk patients. OUTCOME MEASURES (a) Pain prevalence based on VA electronic administrative data and (b) transcripts of interviews with IM staff and patients that mentioned pain. RESULTS Most (70%, 2593/3723) high-risk patients had at least moderate pain. Over one-third (38%, 40/104) of the interviewees mentioned pain or pain care. There were 89 pain-related comments addressing IM impacts on pain care within the 40 interview transcripts. Patient-identified themes were that IM improved communication and responsiveness to pain. PC provider-identified themes were that IM improved workload and access to expertise. IM team member-identified themes were that IM improved pain care coordination, facilitated non-opioid pain management options and mitigated provider compassion fatigue. No negative IM impacts on pain care were mentioned. CONCLUSIONS Pain is common among high-risk patients. Future IM evaluations should consider including a focus on pain and pain care, with attention to impacts on patients, PC providers and IM teams.

Abstract
INTRODUCTION Chronic low back pain may be associated with pathoanatomical, neurophysiological, physical, psychological and social factors; thus, treatments to reduce symptoms are important to improve the quality of life of this population. We aimed to evaluate the effects of transcranial direct current stimulation (tDCS) combined with Pilates-based exercises compared with sham stimulation on pain, quality of life and disability in patients with chronic non-specific low back pain. METHODS AND ANALYSIS This is a protocol for a double-blind randomised controlled trial with participants, outcome assessor and statistician blinded. We will include 36 individuals with a history of non-specific chronic low back pain for more than 12 weeks and minimum pain intensity of 3 points on the Numerical Pain Rating Scale. Individuals will be randomised into two groups: (1) active tDCS combined with Pilates-based exercises and (2) sham tDCS combined with Pilates-based exercises. Three weekly sessions of the protocol will be provided for 4 weeks, and individuals will be submitted to three assessments: the first (T0) will be performed before the intervention protocol, the second (T1) immediately after the intervention protocol and the third (T2) will be a follow-up 1 month after the end of the intervention. We will assess pain, disability, central sensitisation, quality of life, pressure pain threshold, global impression of change, adverse events and medication use. The Numerical Pain Rating Scale and the Roland-Morris Disability Questionnaire will be used at T1 to assess pain and disability, respectively, as primary outcome measures. ETHICS AND DISSEMINATION This trial was prospectively registered in ClinicalTrials.gov website and ethically approved by the Ethics and Research Committee of the Faculty of Health Sciences of Trairi (report number: 5.411.244) before data collection. We will publish the results in a peer-reviewed medical journal and on institution websites. TRIAL REGISTRATION NUMBER ClinicalTrials.gov (NCT05467566).

Abstract
OBJECTIVES It has been reported that maintaining a normal body temperature among surgical patients can reduce the length of hospitalisation by up to 40%, decrease the risk of surgical site infection by 64% and reduce mortality by fourfold. Nurses are primarily responsible for preventing the occurrence of hypothermia among surgical patients. This study assessed nurses' knowledge and practices with respect to perioperative hypothermia prevention in Northwest Ethiopia, and investigated the factors associated with good knowledge and practice. DESIGN Cross-sectional study. SETTING Northwest Amhara Regional State Referral Hospitals, Northwest Ethiopia, 25 March-20 May 2021. PARTICIPANTS 413 nurses working in the perioperative units of five referral hospitals. OUTCOME MEASURES Perioperative hypothermia prevention knowledge and practice among nurses. RESULTS Nearly three-fifths (59.1%; 95% CI: 54.7% to 63.7%) of respondents had good knowledge and about half (50.4%; 95% CI: 45.5% to 55.0%) had good practice with respect to perioperative hypothermia prevention. Factors associated with nurses' knowledge of prevention of perioperative hypothermia included male sex (adjusted OR (AOR): 1.61, 95% CI: 1.02 to 2.53), having a bachelor's degree (AOR: 2.50, 95% CI: 1.25 to 5.00), having a master's degree (AOR: 4.39, 95% CI: 1.45 to 13.20) and training participation (AOR: 3.68, 95% CI: 2.14 to 6.33). Factors associated with nurses' practice of prevention of perioperative hypothermia included working in recovery (AOR: 2.87, 95% CI: 1.08 to 7.58) and intensive care units (AOR: 2.39, 95% CI: 1.09 to 5.22), training participation (AOR: 2.64, 95% CI: 1.53 to 4.57), being satisfied with their job (AOR: 2.15, 95% CI: 1.34 to 3.43) and having good knowledge (AOR: 2.64, 95% CI: 1.63 to 4.27). CONCLUSION Nurses' knowledge and practice of the prevention of perioperative hypothermia were inadequate. Hospital managers need to design and strengthen training programmes and work to enhance job satisfaction.

Abstract
INTRODUCTION Ropivacaine is the most widely used local anaesthetic for peripheral nerve blocks (PNBs). The effects of various concentrations of ropivacaine in PNB have been investigated and compared by many randomised controlled trials (RCTs). This protocol aims to identify the optimal concentration of ropivacaine for PNB in adult patients. METHODS AND ANALYSIS PubMed, EMBASE, the Cochrane library and Web of Science will be searched from their inception to 10 July 2023. RCTs that compare the analgesic effects of different concentrations of ropivacaine for PNB will be included. Retrospective studies, meta-analyses, reviews, case reports, letters, conference abstracts and paediatric studies will be excluded. The duration of analgesia will be named as the primary outcome. Secondary outcomes will include the onset time of motor and sensory blockade, postoperative pain scores, analgesic requirements over 24 hours and the incidence of adverse effects. The study selection, data extraction and quality assessment will be performed by two independent reviewers. Data processing and analysis will be performed by RevMan 5.4. The quality of the evidence will be assessed by the Grading of Recommendations Assessment, Development and Evaluation approach. ETHICS AND DISSEMINATION Ethical approval is not applicable. The results of this study will be submitted to peer-reviewed journals. PROSPERO REGISTRATION NUMBER CRD42023406362.

Effect of whole-body cryotherapy versus placebo cryotherapy on joint pain induced by aromatase inhibitors in women with early stage breast cancer: a randomised clinical trial. BMJ Open 2023; 13:e071756. [PMID: 38070928 PMCID: PMC10729259 DOI: 10.1136/bmjopen-2023-071756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 10/11/2023] [Indexed: 12/18/2023] Open
Abstract
INTRODUCTION Hormone therapy (HT) is a major adjuvant treatment for breast cancer. Despite their effectiveness, aromatase inhibitors can cause several side effects, including arthralgia in 35%-50% of patients. These side effects frequently lead to the premature discontinuation of HT. Whole-body cryotherapy (WBC) can be used for managing arthritic pain. The primary objective of this study will be to evaluate the effect of WBC on aromatase-induced joint pain, compared with placebo cryotherapy, in patients with hormone-dependent breast cancer receiving adjuvant aromatase inhibitors. The secondary objectives will be to evaluate WBC safety and its effect on analgesic consumption, HT adherence and quality of life. METHODS AND ANALYSIS In this randomised, placebo-controlled, double-blinded clinical trial, 56 patients with aromatase inhibitor-induced joint pain and a Brief Pain Inventory-Short Form (BPI-SF) score ≥3 for the worst pain experienced in the previous week will be randomised into the WBC or placebo cryotherapy arm (10 sessions in each group). The primary outcome will be the BPI-SF score at week 6 post-treatment. The secondary outcomes will include the BPI-SF scores at months 3 and 6 post-treatment, the BPI-SF pain severity index and pain interference index, the Health Assessment Questionnaire score, the number of days of aromatase inhibitor treatment and analgesic consumption in the 15 days before the visits at week 6 and months 3 and 6 after cryotherapy. The incidence of adverse events will also be investigated. ETHICS AND DISSEMINATION Ethics approval was obtained from the Ethics Committee Est IV of Hospital Civil, Strasbourg, France. Protocol V.5 was approved in December 2022. The results will be disseminated in a peer-reviewed journal and presented at international congresses. TRIAL REGISTRATION NUMBER NCT05315011.

Abstract
OBJECTIVES Fibromyalgia treatment trends vary globally; however, the trend in South Korea has not been investigated yet. This study aimed to analyse the fibromyalgia treatment trends in South Korea. DESIGN Retrospective, observational study using serial cross-sectional data. SETTING The National Patient Samples of the Korean Health Insurance Review & Assessment Service from 2011 to 2018 were used. PARTICIPANTS A total of 31 059 patients with fibromyalgia were included in this study. The basic characteristics of the patients were stratified by sex, age and comorbidity. A patient was considered to have a condition if it was recorded as a principal diagnosis at least once in a year. PRIMARY AND SECONDARY OUTCOME MEASURES Trends in the types of medical visits and prescribed treatments were investigated and the values are presented as rates per 100 patients. The types of pharmacological treatment were presented according to the existing clinical guidelines. Additionally, combination prescription trends and associated characteristics were investigated. RESULTS Of the patients, 66.2% were female. Visits to internal medicine departments showed the most significant increase (2011: 11.34; 2018: 21.99; p<0.001). Non-pharmacological treatment rates declined (physical therapy 2011: 18.11; 2018: 13.69; p<0.001, acupuncture 2011: 52.03; 2018: 30.83; p<0.001). Prescription rates increased for analgesics, relaxants, antiepileptics and antidepressants. Non-steroidal anti-inflammatory drug prescriptions had the highest increase (2011: 27.65; 2018: 40.02; p<0.001). Serotonin-norepinephrine reuptake inhibitor prescriptions showed significant growth (2011: 2.4; 2018: 8.05; p<0.001). Prescription durations were generally longer for women (p<0.001), with higher rate increases in this group. Combinations of ≥3 medication classes increased (2011: 8.2; 2018: 9.64; p=0.041). Women were more likely to receive combination prescriptions (crude OR 1.47 (95% CI 1.29 to 1.68), adjusted 1.18 (95% CI 1.03 to 1.36)). CONCLUSIONS Our findings provide basic reference data for the development and application of national guidelines for fibromyalgia.

Abstract
INTRODUCTION A head and neck cancer (HNC) diagnosis significantly impacts a patient's quality of life (QOL). Palliative care potentially improves their QOL. We will conduct a scoping review to identify existing knowledge about palliative care interventions for patients with HNC. METHODS AND ANALYSIS This scoping review was designed in accordance with the JBI Manual for Evidence Synthesis: Scoping Reviews and will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Our eligibility criteria follow the Population, Intervention, Comparison or Control, Outcomes and Study characteristics framework. The population is adult patients with locally advanced, metastatic, unresectable and/or recurrent HNC. We include peer-reviewed journal articles and articles in the press, in English, reporting on palliative care interventions with at least two of the eight National Consensus Project on Clinical Practice Guidelines for Quality Palliative Care domains; studies with and without comparators will be included. The outcomes are patient QOL (primary) and symptom severity, patients' satisfaction with care, patients' mood, advance care planning and place of death (secondary). We developed a search strategy across ten databases, to be searched from the inception to 11 September 2023: Medline ALL (Medline and EPub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations), Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase Classic+Embase, Emcare and PsycINFO all from the OvidSP platform; CINAHL from EBSCOhost, Scopus from Elsevier, Web of Science from Clarivate and Global Index Medicus from WHO. We will extract data using a piloted data form and analyse the data through descriptive statistics and thematic analysis. ETHICS AND DISSEMINATION Ethics approval is not needed for a scoping review. We will disseminate the findings to healthcare providers and policy-makers by publishing the results in a scientific journal.

Abstract
INTRODUCTION Millions of people survive injuries to the central or peripheral nervous system for which neurorehabilitation is required. In addition to the physical and cognitive impairments, many neurorehabilitation patients experience pain, often not widely recognised and inadequately treated. This is particularly true for multiple sclerosis (MS) patients, for whom pain is one of the most common symptoms. In clinical practice, pain assessment is usually conducted based on a subjective estimate. This approach can lead to inaccurate evaluations due to the influence of numerous factors, including emotional or cognitive aspects. To date, no objective and simple to use clinical methods allow objective quantification of pain and the diagnostic differentiation between the two main types of pain (nociceptive vs neuropathic). Wearable technologies and artificial intelligence (AI) have the potential to bridge this gap by continuously monitoring patients' health parameters and extracting meaningful information from them. Therefore, we propose to develop a new automatic AI-powered tool to assess pain and its characteristics during neurorehabilitation treatments using physiological signals collected by wearable sensors. METHODS AND ANALYSIS We aim to recruit 15 participants suffering from MS undergoing physiotherapy treatment. During the study, participants will wear a wristband for three consecutive days and be monitored before and after their physiotherapy sessions. Measurement of traditionally used pain assessment questionnaires and scales (ie, painDETECT, Doleur Neuropathique 4 Questions, EuroQoL-5-dimension-3-level) and physiological signals (photoplethysmography, electrodermal activity, skin temperature, accelerometer data) will be collected. Relevant parameters from physiological signals will be identified, and AI algorithms will be used to develop automatic classification methods. ETHICS AND DISSEMINATION The study has been approved by the local Ethical Committee (285-2022-SPER-AUSLBO). Participants are required to provide written informed consent. The results will be disseminated through contributions to international conferences and scientific journals, and they will also be included in a doctoral dissertation.

Abstract
INTRODUCTION Sciatica can be very painful and, in most cases, is due to pressure on a spinal nerve root from a disc herniation with associated inflammation. For some patients, the pain persists, and one management option is a spinal epidural steroid injection (ESI). The aim of an ESI is to relieve leg pain, improve function and reduce the need for surgery. ESIs work well in some patients but not in others, but we cannot identify these patient subgroups currently. This study aims to identify factors, including patient characteristics, clinical examination and imaging findings, that help in predicting who does well and who does not after an ESI. The overall objective is to develop a prognostic model to support individualised patient and clinical decision-making regarding ESI. METHODS POiSE is a prospective cohort study of 439 patients with sciatica referred by their clinician for an ESI. Participants will receive weekly text messages until 12 weeks following their ESIand then again at 24 weeks following their ESI to collect data on leg pain severity. Questionnaires will be sent to participants at baseline, 6, 12 and 24 weeks after their ESI to collect data on pain, disability, recovery and additional interventions. The prognosis for the cohort will be described. The primary outcome measure for the prognostic model is leg pain at 6 weeks. Prognostic models will also be developed for secondary outcomes of disability and recovery at 6 weeks and additional interventions at 24 weeks following ESI. Statistical analyses will include multivariable linear and logistic regression with mixed effects model. ETHICS AND DISSEMINATION The POiSE study has received ethical approval (South Central Berkshire B Research Ethics Committee 21/SC/0257). Dissemination will be guided by our patient and public engagement group and will include scientific publications, conference presentations and social media.

INTRODUCTION The goal of this study is to gain firsthand insights from individuals with a history of opioid use disorder (OUD) using medication for OUD on their experiences with postoperative pain care. This study also seeks to describe the experiences of nurses caring for individuals with OUD, and the challenges they may face managing complaints of pain in this population. Research suggests that hospitals can significantly enhance the quality of the care they deliver by investigating an individual's experience in the care setting. These insights will allow for the development of strategies for nurses to deepen their understanding of and, therefore, advocate and improve care for, this vulnerable and often stigmatised population. METHODS AND ANALYSIS A qualitative descriptive study will be conducted consisting of a prescreening and demographics questionnaire, and individual semistructured interviews with approximately 10-15 individuals with OUD having recently undergone surgery and 10-15 nurses providing care for this population for a total of 20-30 interviews. This approach involves the collection of separate but complementary data (ie, perceptions of individuals with OUD and nurses) concerning the phenomena of postoperative pain management. Sampling will continue until data saturation is reached. Descriptive statistics and thematic analysis will then be used. Reporting will adhere to the Standards for Reporting Qualitative Research checklist. ETHICS AND DISSEMINATION This study received approval from the Institutional Review Board at Northeastern University. Alongside peer-reviewed journal publications, the findings will be presented at relevant conferences, and a plain language summary will be distributed to the study participants.

Abstract
INTRODUCTION Chronic pain is a common health problem that is not efficiently managed by standard analgesic treatments. There is evidence that treatment resistance may result from maladaptive brain changes in areas that are fundamental to the perception of pain. Knee osteoarthritis is one of the most prevalent causes of chronic pain and commonly associated with negative affect. Chronic knee osteoarthritis pain is also associated with altered right anterior insula functional connectivity. We posit that reversal of these brain circuit alterations may be critical to alleviate chronic pain and associated negative affect, and that this can be achieved through non-invasive neuromodulation techniques. Despite growing interest in non-invasive neuromodulation for pain relief and proven efficacy in depression, results in chronic pain are mixed with limited high-quality evidence for clinical and mechanistic efficacy. Limitations include patient heterogeneity, imprecision of target selection, uncertain blinding and protocols that may deliver pulses at subclinical efficacy. METHODS AND ANALYSIS We hence developed an optimised treatment protocol of connectivity-guided intermittent theta-burst stimulation (iTBS) targeting the left dorsolateral prefrontal cortex with accelerated delivery on four consecutive days (allowing 4 days within the same week as protocol variation) with five daily treatment sessions that will be piloted in a sham-controlled design in 45 participants with chronic knee pain. This pilot study protocol will assess feasibility, tolerability and explore mechanistic efficacy through serial functional/structural magnetic resonance imaging (MRI) and quantitative sensory testing. ETHICS AND DISSEMINATION This pilot trial has been approved by the Ethics Committee Cornwall and Plymouth.Results of the pilot trial will be submitted to peer-reviewed journals, presented at research conferences and may be shared with participants and PPI/E advisors.

[PMID: 37813540 PMCID: PMC10565158 DOI: 10.1136/bmjopen-2023-072566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 08/31/2023] [Indexed: 10/13/2023] Open
Abstract
INTRODUCTION Although pain experienced at dressing change has been reported as the worst aspect of living with chronic wounds, UK guidance for their management is primarily tailored to wound healing and only attends to pain as a secondary consideration. Consequently, there is little up-to-date guidance that specifically addresses how patients, carers and healthcare professionals should manage wound-related pain at dressing change. This mapping review will identify, describe and appraise the existing research evidence for strategies used to assess pain intensity and prevent or alleviate pain at dressing change in chronic wounds. In addition, it will highlight areas for future research and inform the development of up-to-date guidance for healthcare professionals. METHODS AND ANALYSIS We will search MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily (via Ovid SP), Embase (via Ovid SP), Cochrane Central Register of Controlled Trials (via Wiley Cochrane Library), Cumulative Index of Nursing and Allied Health Literature (via EBSCO) and the Web of Science Citation Index Expanded and Social Sciences Citation Index (via Clarivate Analytics). Screening will be undertaken independently by two reviewers, with any disagreements resolved through discussion. Included studies will be subject to coding, using a tested data extraction tool, by two reviewers working independently. The methodological quality of the studies included will be reviewed using quality assessment instruments appropriate for each study design (Cochrane Risk of Bias tool (RoB 2); Risk of Bias in Non-randomised Studies of interventions tool; Critical Appraisal Skills Programme tool). Data will be described narratively and also presented visually in an interactive web-based evidence and gap map. ETHICS AND DISSEMINATION As this mapping review does not collect original data, ethical approval is not applicable. Findings will be disseminated via a written report, an interactive online mapping tool and in peer-reviewed journals and conference presentations. PROSPERO REGISTRATION NUMBER CRD42021260130.

Abstract
INTRODUCTION Gabapentinoids are among the most widely prescribed pain medications. However, there is growing evidence to suggest that gabapentinoids may be associated with dependence and misuse. The aim of this systematic review is to synthesise the qualitative literature on gabapentinoid misuse and symptoms of dependence. The findings of this study will inform efforts to mitigate emerging harms. METHODS AND ANALYSIS A systematic review of qualitative research will explore lived experiences of misuse and symptoms of dependence among people who use gabapentinoids. Six databases (MEDLINE, Scopus, Web of Science, CINAHL, EMBASE and PsycINFO) and grey literature sources will be searched from inception to May 2023. Qualitative studies that include people with lived experiences of gabapentinoid misuse and symptoms of gabapentinoid dependence will be included. Reference lists of included studies will also be screened for additional studies. The methodological quality of included studies will be appraised using the Critical Appraisal Skills Programme qualitative checklist, and higher quality studies will be prioritised in the thematic synthesis. The GRADE-CERQual approach will be used to assess confidence in the overall findings of the review. ETHICS AND DISSEMINATION Ethical approval is not required for this systematic review. The findings of this review will be disseminated in peer-reviewed journals, at conferences and on social media. PROSPERO REGISTRATION NUMBER CRD42023401832.

Abstract
OBJECTIVES To explore the elements and composition of care provided by general practitioners (GPs), physiotherapists (PTs) and chiropractors (DCs) to patients with low back pain (LBP). DESIGN Observational study. SETTING Primary care setting, Denmark. PARTICIPANTS Primary care clinicians (GPs, PTs and DCs) in the Region of Southern Denmark were invited to register consecutive adult patient visits with LBP as the primary complaint. PRIMARY OUTCOME MEASURES Clinicians reported care elements provided to patients with LBP. Elements varied due to professional differences (eg, prescriptive rights). Data were descriptively analysed, on group and individual levels, for frequency and combination of care elements, and practice patterns were explored with latent class analysis. RESULTS The clinicians (33 GPs, 67 PTs and 43 DCs with a median experience of 15 years and 59% were females) registered 3500 patient visits. On average, the visits involved patients aged 51 years, and 51% were with females. The frequencies of common care elements across professions were information (42%-56% of visits between professions) and advice (56%-81%), while other common elements for GPs were pain medication (40%) and referrals to PTs (36%), for PTs, use of exercises (81%) and for DCs, use of manual therapy (96%). Substantial variation was observed within professions and distinct practice patterns, with different focuses of attention to information and advice versus exercise and manual therapy, were identified for PTs and DCs. CONCLUSIONS These data indicate substantial variation in the care elements provided by GPs, PTs and DCs to LBP patients. The compositions of care and practice patterns identified challenge the understanding of usual care as a uniform concept and professions as homogeneous groups. Strategic use of particular care elements in different parts of treatment courses is indicated. Longitudinal data and qualitative enquiry are needed to assess if or how care is tailored to individual patients.

Abstract
INTRODUCTION Oral lichen planus (OLP) is a chronic, inflammatory oral condition leading to a range of symptoms from mild discomfort to severe pain, affecting patients' quality of life. Standard therapy involves the use of topical corticosteroids, although some patients respond insufficiently or develop resistance to therapy. We aim to explore if adding cepharanthine, an herbal extract from Stephania cepharantha Hayata, can enhance the efficacy of corticosteroid therapy in symptomatic OLP. METHODS AND ANALYSIS This open-label, parallel-group, multi-centre, randomised controlled study will be conducted at three Japanese hospitals. It will compare safety and efficacy of integrated oral cepharanthine and corticosteroid therapy versus standard corticosteroid therapy. 50 symptomatic OLP patients will be randomised 1:1 to receive cepharanthine (30 mg/day) plus topical dexamethasone, or topical dexamethasone alone for 8 weeks. The primary outcome will be changed in pain intensity while drinking room-temperature water, measured on a visual analogue scale. The primary outcome is the change in pain intensity from baseline when drinking room-temperature water, evaluated using a visual analogue scale. Secondary outcomes are changes in the longest diameter of the target lesion from baseline to weeks 4 and 8, improvement and deterioration rates according to appearance and severity criteria at weeks 4 and 8, change in pain intensity when drinking room-temperature water from baseline to week 4, changes in pain intensity at rest from baseline to weeks 4 and 8, and the rates of adverse events. ETHICS AND DISSEMINATION This protocol was approved by the Certified Review Board of Nara Medical University (CRB5200002). Participants will provide informed consent. Results will be disseminated in peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER Japan Registry of Clinical Trials (jRCTs051220130).

Abstract
OBJECTIVES Ocular pain is a commonly reported finding in the intravitreal injection procedure, but post-injection experiences and patient adherence to treatment remain underexplored. We therefore aimed to identify key variations in the intravitreal injection procedure that may influence pain, and to gain insights into the post-injection experience and treatment adherence from the perspective of patients and practitioners. DESIGN Qualitative semistructured interview study using reflexive thematic analysis of transcripts. SETTING Hospital Eye Clinic in Wales, UK. Interviews were conducted between May and September 2019. PARTICIPANTS Purposive sample of patients aged ≥50 years with neovascular age-related macular degeneration and no other retinal pathology who had received at least six intravitreal injections, and practitioners including ophthalmologists, registered nurses and optometrists who performed intravitreal injections at the research site. RESULTS Data saturation was reached with 21 interviews: 14 patients and 7 practitioners. Three main themes were identified from the analysis: fear of losing eyesight and treatment anxiety influence patient adherence to treatment, variability in pain experience during treatment, and post-injection experience and impact on patient recovery. To reassure patients feeling apprehensive about the injections, practitioners promoted safety and trust, and used techniques to manage anxiety. Key variations that may influence pain identified were application of antiseptic or anaesthetic, injecting methods and communication. During injection, patients reported a dull-aching and sharp pain, contrary to practitioners' perspective of feeling a 'pressure'. Patients described prolonged soreness and irritation of up to 36 hours post-injection affecting their sleep and recovery. CONCLUSION Establishing rapport supported patients to recognise the necessity of ongoing treatment to prevent sight loss; however, inadequate pain management led to undesirable outcomes. Practitioners should use pain assessment tools during and immediately after injection and provide ongoing consistent information to help patients manage pain at home.

Abstract
INTRODUCTION Subgroups for Targeted Treatment Back Tool (SBT) is a brief multiple-construct risk prediction tool for patients with low back pain (LBP). Thus far, the predictive ability of this tool has been inconsistent. Therefore, we aim to conduct a literature review on the predictive ability of the SBT to determine the outcomes of patients with LBP. The results of this review should improve the ability of the SBT to predict poor outcomes in patients with LBP. METHODS AND ANALYSIS Databases including PubMed, EMBASE, Cochrane Central, Web of Science, Chinese National Knowledge Infrastructure Databases, Chinese Science and Technology Journal Database, and Wanfang will be searched for studies on SBT and LBP from their inception until 31 March 2023. Longitudinal studies investigating the association between SBT subgroups and LBP outcomes, including pain, disability and quality of life, will be included. The identified studies will be independently screened for eligibility by two reviewers. A standardised sheet will be used to extract data. The Newcastle-Ottawa Scale will be used to assess the methodological quality of the included studies. Heterogeneity will be evaluated by the χ2 test with Cochran's Q statistic and quantified by the I2 statistic. The results will be synthesised qualitatively and presented as pooled risk ratios or beta coefficients quantitatively. The results will also be presented using their 95% confidence limits. Publication bias will be assessed using the method proposed by Egger and by visual inspection of funnel plots. ETHICS AND DISSEMINATION This study is a secondary analysis of original studies that received ethics approval. Therefore, prior ethical approval is not required for this study. The findings will be submitted to relevant peer-reviewed journals for publication and presented at profession-specific conferences.

Abstract
INTRODUCTION A substantial proportion of COVID-19 survivors continue to have symptoms more than 3 months after infection, especially of those who required medical intervention. Lasting symptoms are wide-ranging, and presentation varies between individuals and fluctuates within an individual. Improved understanding of undulation in symptoms and triggers may improve efficacy of healthcare providers and enable individuals to better self-manage their Long Covid. We present a protocol where we aim to develop and examine the feasibility and usability of digital home monitoring for capturing daily fluctuation of symptoms in individuals with Long Covid and provide data to facilitate a personalised approach to the classification and management of Long Covid symptoms. METHODS AND ANALYSIS This study is a longitudinal prospective cohort study of adults with Long Covid accessing 10 National Health Service (NHS) rehabilitation services in the UK. We aim to recruit 400 people from participating NHS sites. At referral to study, 6 weeks and 12 weeks, participants will complete demographic data (referral to study) and clinical outcome measures, including ecological momentary assessment (EMA) using personal mobile devices. EMA items are adapted from the COVID-19 Yorkshire Rehabilitation Scale items and include self-reported activities, symptoms and psychological factors. Passive activity data will be collected through wrist-worn sensors. We will use latent class growth models to identify trajectories of experience, potential phenotypes defined by co-occurrence of symptoms and inter-relationships between stressors, symptoms and participation in daily activities. We anticipate that n=300 participants provide 80% power to detect a 20% improvement in fatigue over 12 weeks in one class of patients relative to another. ETHICS AND DISSEMINATION The study was approved by the Yorkshire & The Humber-Bradford Leeds Research Ethics Committee (ref: 21/YH/0276). Findings will be disseminated in peer-reviewed publications and presented at conferences. TRIAL REGISTRATION NUMBER ISRCTN15022307.

Abstract
INTRODUCTION Insufficient identification and understanding of risk factors make musicians engaging in professional practice particularly vulnerable to musculoskeletal pain. To support positive music learning and good mental, physical, and social health, student musicians need health support tailored to their needs and their instrumental practice. However, these preventive actions must be based on sound scientific approaches that reliably identify the most relevant risk factors. MuSa is a cross-sectional study examining contextual and internal risk variables associated with playing-related musculoskeletal disorders in student musicians. METHOD AND ANALYSIS The design is a monocentric cross-sectional study involving student musicians in Bachelor's 1, 2, 3 and Master's 1, 2. Free-form questions will identify students' lifestyle characteristics and work habits, and validated questionnaires will evaluate the interaction between pain due to music practice and psychological and physical risk factors. All data will first be analysed descriptively. Psychological network analysis will be used to explore the overall correlational structure of the dataset. A subgroup comparative analysis will be then applied according to the instrumental subcategories and work postures, including singers. ETHICS AND DISSEMINATION The full protocol was approved by the Swiss Ethics Committee 'Commission Cantonale d'Ethique de la Recherche sur l'être humain de Genève' (CCER, no. 2022-02206) on 13 February 2023. Outcomes will be disseminated through publication in peer-reviewed journals and presentations at conferences.

Abstract
OBJECTIVES Chronic pain (CP) is a poorly recognised and frequently inadequately treated condition affecting one in five adults. Reflecting on sociodemographic disparities as barriers to CP care in Canada was recently established as a federal priority. The objective of this study was to assess sex and gender differences in healthcare utilisation trajectories among workers living with CP. DESIGN Retrospective cohort study. PARTICIPANTS This study was conducted using the TorSaDE Cohort which links the 2007-2016 Canadian Community Health Surveys and Quebec administrative databases (longitudinal claims). Among 2955 workers living with CP, the annual number of healthcare contacts was computed during the 3 years after survey completion. OUTCOME Group-based trajectory modelling was used to identify subgroups of individuals with similar patterns of healthcare utilisation over time (healthcare utilisation trajectories). RESULTS Across the study population, three distinct 3-year healthcare utilisation trajectories were found: (1) low healthcare users (59.9%), (2) moderate healthcare users (33.6%) and (3) heavy healthcare users (6.4%). Sex and gender differences were found in the number of distinct trajectories and the stability of the number of healthcare contacts over time. Multivariable analysis revealed that independent of other sociodemographic characteristics and severity of health condition, sex-but not gender-was associated with the heavy healthcare utilisation longitudinal trajectory (with females showing a greater likelihood; OR 2.6, 95% CI 1.6 to 4.1). CONCLUSIONS Our results underline the importance of assessing sex-based disparities in help-seeking behaviours, access to healthcare and resource utilisation among persons living with CP.

Abstract
OBJECTIVE To gain an insight into coping strategies that people living with chronic pain use to self-manage their pain. DESIGN This qualitative Patient-oriented Research study used the Patient and Community Engagement Research approach. It was conducted by people with chronic pain lived experience, ensuring that patient perspective and needs were considered and addressed throughout the research cycle. Purposeful sampling was used for recruiting individuals living with chronic pain. A focus group and one-on-one semi-structured interviews were conducted via videoconference. The data were analysed iteratively using inductive thematic analysis and narrative story analysis. SETTING Calgary, Alberta, Canada. PARTICIPANTS Eleven adult participants, between the ages of 18 and 65, who self-identified as living with chronic pain for greater than 2 years. RESULTS Three main themes emerged from the data: (1) the elements of chronic pain, (2) the chronic pain journey to acceptance and (3) daily coping strategies for chronic pain. Participants thought it was important to discuss these three themes because the daily coping strategies that they employed at any given time (theme 3) depended on the factors discussed in themes 1 and 2. Overlaying all of this is also a grieving process that people living with chronic pain may have to go through more than once. Participants also identified recommendations for healthcare professionals to support people living with chronic pain. CONCLUSIONS Dealing with chronic pain affects all aspects of a person's life and involves a grieving process. When treating patients with chronic pain, it is important for healthcare professionals to understand the journey that people living with chronic pain go through, not just coping strategies. Diagnosis is critical for a patient's acceptance and in helping them find their new normal where they can employ daily coping strategies to manage their pain.

Abstract
OBJECTIVE The substitution of an in-study control population with a historical control (HC) population is considered a viable option for reducing the necessary recruitment of control patients. However, it is necessary to evaluate whether this method is applicable to studies on indications targeting endometriosis-associated pelvic pain (EAPP). This study aims to evaluate the potential bias in the results of an EAPP study with an HC arm. METHODS For this case study, we re-evaluated data from a randomised, placebo-controlled trial using dienogest daily to treat EAPP with an HC arm based on data from a second randomised, placebo-controlled trial in the same indication. Propensity Score (PS) matching was used to match between the treatment and HC arm on all baseline variables. To evaluate the effect of matching on the introduced bias, we evaluated efficacy parameters with the full treatment and control group, as well as the matched group. RESULTS The difference between means (placebo minus treatment) in change in pain, as measured on the Visual Analogue Scale from baseline to end of treatment, deviates in the comparison treatment/pool of HC (7.15 (0.22 to 14.08)) from the overall in-study group (reference: 11.89 (6.06 to 17.73)). After PS matching on the baseline variables, the difference between means (11.79 (4.09 to 19.5)) is close to the reference. CONCLUSIONS Using HC with PS matching has proven to be useful in the setting of treating EAPP, while emphasis must be given to the selection mechanism and the underlying assumptions. This case study has shown that even for studies which are very similar in design, heterogeneity and between-study variations are present. With the use of an HC arm, it was possible to reproduce similar results than in the original study, while the PS matching improved the comparability considerably. For the main endpoint, PS matching could reproduce the original study results. TRIAL REGISTRATION NUMBER NCT00225199, NCT00185341.

Abstract
OBJECTIVES To establish proof of concept of a prehabilitation intervention, a combination of education and behavioural change, preceding a physical activity programme in people with fibromyalgia (FM). SETTINGS Open-label, feasibility clinical trial. PARTICIPANTS Eleven people with FM (10 women). INTERVENTIONS The prehabilitation intervention consisted of 4 weeks, 1 weekly session (~1 to 1.5 hours), aimed to increase self-efficacy and understand why and how to engage in a gentle and self-paced physical activity programme (6 weeks of walking with telephone support). PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome was the acceptability and credibility of the intervention by means of the Credibility/Expectancy Questionnaire. Secondary outcomes comprised scales to measure FM severity, specific symptoms and sedentary behaviour. An exit interview was conducted to identify the strengths and weaknesses and barriers to the intervention. RESULTS One participant dropped out due to finding the walking programme excessively stressful. Participants expected the intervention would improve their symptoms by 22%-38% but resulted in 5%-26% improvements. Participants would be confident in recommending this intervention to a friend who experiences similar problems. The interviews suggested that the fluctuation of symptoms should be considered as an outcome and that the prehabilitation intervention should accomodate these fluctuation. Additional suggestions were to incorporate initial interviews (patient-centred approach), to tailor the programmes to individuals' priorities and to offer a variety of physical activity programmes to improve motivation. CONCLUSIONS This feasibility study demonstrated that our novel approach is acceptable to people with FM. Future interventions should pay attention to flexibility, symptoms fluctuation and patients support. TRIAL REGISTRATION NUMBER NCT03764397.
