The Adaptation of Pain Assessment Tools from High-Income to Low- and Middle-Income Countries: Psychometric Properties of a Set of Chronic Pain Questionnaires in Mongolian and New Zealand Patient Samples.

OBJECTIVE: Chronic pain is a leading cause of disability in low- and middle-income countries; however, pain assessment tools have generally been developed and validated in high-income countries. This study examines the psychometric properties of a set of translated pain (and distress) questionnaires in Mongolia and documents the characteristics of people seeking treatment for chronic pain in Mongolia, compared with those in New Zealand, which is representative of high-income countries. DESIGN: Cross-sectional, observational. SETTING: Hospital-based pain treatment centers in New Zealand and Mongolia. SUBJECTS: People seeking treatment for chronic pain in Mongolia (N = 142) and New Zealand (N = 159). METHODS: The Brief Pain Inventory, the Depression Anxiety Stress Scale-21, the Pain Catastrophizing Scale, and the Pain Self-Efficacy Questionnaire were translated into Mongolian and administered to patients attending a hospital-based pain service. Questionnaires that were completed by patients in New Zealand were used for comparisons. Internal reliability, convergent validity, and factor structure were assessed in both groups. RESULTS: Patients in Mongolia were older and reported lower pain intensity, interference, and distress and higher pain self-efficacy than those in New Zealand. The translated questionnaires had good internal consistencies, and the relationships between pain variables were similar across both groups. The factor structure for the Pain Catastrophizing Scale was consistent across both groups, but this was not the case for the Brief Pain Inventory or the Depression Anxiety Stress Scale-21. CONCLUSIONS: Findings indicate that some pain outcome measures may be appropriate for use in Mongolia and should be investigated in other low- and middle-income countries.

What does best practice care for musculoskeletal pain look like? Eleven consistent recommendations from high-quality clinical practice guidelines: systematic review.

OBJECTIVES: To identify common recommendations for high-quality care for the most common musculoskeletal (MSK) pain sites encountered by clinicians in emergency and primary care (spinal (lumbar, thoracic and cervical), hip/knee (including osteoarthritis [OA] and shoulder) from contemporary, high-quality clinical practice guidelines (CPGs). DESIGN: Systematic review, critical appraisal and narrative synthesis of MSK pain CPG recommendations. ELIGIBILITY CRITERIA: Included MSK pain CPGs were written in English, rated as high quality, published from 2011, focused on adults and described development processes. Excluded CPGs were for: traumatic MSK pain, single modalities (eg, surgery), traditional healing/medicine, specific disease processes (eg, inflammatory arthropathies) or those that required payment. DATA SOURCES: Four scientific databases (MEDLINE, Embase, CINAHL and Physiotherapy Evidence Database) and four guideline repositories. RESULTS: 6232 records were identified, 44 CPGs were appraised and 11 were rated as high quality (low back pain: 4, OA: 4, neck: 2 and shoulder: 1). We identified 11 recommendations for MSK pain care: ensure care is patient centred, screen for red flag conditions, assess psychosocial factors, use imaging selectively, undertake a physical examination, monitor patient progress, provide education/information, address physical activity/exercise, use manual therapy only as an adjunct to other treatments, offer high-quality non-surgical care prior to surgery and try to keep patients at work. CONCLUSION: These 11 recommendations guide healthcare consumers, clinicians, researchers and policy makers to manage MSK pain. This should improve the quality of care of MSK pain.

Poor overall quality of clinical practice guidelines for musculoskeletal pain: a systematic review.

OBJECTIVES: Undertake a systematic critical appraisal of contemporary clinical practice guidelines (CPGs) for common musculoskeletal (MSK) pain conditions: spinal (lumbar, thoracic and cervical), hip/knee (including osteoarthritis) and shoulder. DESIGN: Systematic review of CPGs (PROSPERO number: CRD42016051653).Included CPGs were written in English, developed within the last 5 years, focused on adults and described development processes. Excluded CPGs were for: traumatic MSK pain, single modalities (eg, surgery), traditional healing/medicine, specific disease processes (eg, inflammatory arthropathies) or those that required payment. DATA SOURCES AND METHOD OF APPRAISAL: Four scientific databases (MEDLINE, Embase, CINAHL and Physiotherapy Evidence Database) and four guideline repositories. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument was used for critical appraisal. RESULTS: 4664 records were identified, and 34 CPGs were included. Most were for osteoarthritis (n=12) or low back pain (n=11), most commonly from the USA (n=12). The mean overall AGREE II score was 45% (SD=19.7). Lowest mean domain scores were for applicability (26%, SD=19.5) and editorial independence (33%, SD=27.5). The highest score was for scope and purpose (72%, SD=14.3). Only 8 of 34 CPGS were high quality: for osteoarthritis (n=4), low back pain (n=2), neck (n=1) and shoulder pain (n=1).

Revisiting the Pain Resource Nurse Role in Sustaining Evidence-Based Practice Changes for Pain Assessment and Management.

BACKGROUND: Effective pain management is unlikely to occur without consistent and timely assessments. To improve assessment and management of pain, ward-based pain resource nurses were introduced in 2007 to facilitate hospital-wide evidence-based practice changes using three key targets. One-year post implementation of this quality improvement project, promising results were revealed. AIMS: The purpose of this study, 8 years post implementation, was to (a) evaluate sustained practice improvements in pain assessment and management, (b) assess current pain resource nurse knowledge and attitudes to pain, (c) explore characteristics of the pain resource nurse role, as well as (d) any perceived contextual changes regarding study findings. METHODS: A mixed-methods approach was used to address study aims. Quantitative data were collected from documentation audits and a "Knowledge and Attitudes Survey Regarding Pain." Qualitative interviews explored the characteristics of the pain resource nurse role, and a focus group discussion explored the context of change. RESULTS: Significant improvements were observed for the documentation of pain scores on admission and for each nursing shift. Survey results highlighted potential knowledge deficits in key practice areas, even though interview findings suggested that pain resource nurses provided a resource for peers, raised awareness of best practice, and imparted knowledge to other ward staff. An important facilitator for the pain resource nurse role was the ongoing collaboration and support from specific pain teams, and barriers to engage in the role were competing workload priorities, and limited awareness among other ward staff. LINKING EVIDENCE TO ACTION: Implementing and sustaining evidence-based practice change in clinical practice is challenging. Ongoing evaluation is necessary for identifying the long-term implications of practice improvement interventions and issues that influence the adoption of evidence-based practice. Strategies to address barriers, and to increase awareness and engagement of the pain resource nurse role with wider collaboration require further investigation.

Persistent pelvic pain: rising to the challenge.

Persistent pelvic pain is a common condition, with up to 20% of those affected reporting severe pain. Once end organ disease has been assessed, further investigations should be minimised. Persistent pelvic pain as a hyperalgesic neuropathic pain condition must be considered in the differential diagnosis. A multidisciplinary assessment and management plan, prepared by the co-ordinating gynaecologist in consultation with the general practitioner, physiotherapist and psychologist (with gastroenterological, urological and pain medicine specialist input as deemed appropriate), is strongly recommended.

"Listen to me, learn from me": a priority setting partnership for shaping interdisciplinary pain training to strengthen chronic pain care.

ABSTRACT: What are the care-seeking priorities of people living with chronic pain and carers and how can these shape interdisciplinary workforce training to improve high-value pain care? Phase 1: Australian people living with chronic pain (n = 206; 90% female) and carers (n = 10; 40% female) described their pain care priorities (eDelphi, round 1). A coding framework was inductively derived from 842 pain care priorities (9 categories, 52 priorities), including validation; communication; multidisciplinary approaches; holistic care; partnerships; practitioner knowledge; self-management; medicines; and diagnosis. Phase 2: In eDelphi round 2, panellists (n = 170; valid responses) rated the importance (1 = less important; 9 = more important) of the represented framework. In parallel, cross-discipline health professionals (n = 267; 75% female) rated the importance of these same priorities. Applying the RAND-UCLA method (panel medians: 1-3: "not important," 4-6: "equivocal," or 7-9: "important"), "important" items were retained where the panel median score was >7 with panel agreement ≥70%, with 44 items (84.6%) retained. Specific workforce training targets included the following: empathic validation; effective, respectful, safe communication; and ensuring genuine partnerships in coplanning personalised care. Panellists and health professionals agreed or strongly agreed (95.7% and 95.2%, respectively) that this framework meaningfully reflected the importance in care seeking for pain. More than 74% of health professionals were fairly or extremely confident in their ability to support care priorities for 6 of 9 categories (66.7%). Phase 3: An interdisciplinary panel (n = 5) mapped an existing foundation-level workforce training program against the framework, identifying gaps and training targets. Recommendations were determined for framework adoption to genuinely shape, from a partnership perspective, Australian interdisciplinary pain training.

Psychological factors can cause false pain classification on painDETECT.

Background and aims The painDETECT questionnaire (PD-Q) has been widely used as a screening tool for the identification of neuropathic pain (NeP) as well as a tool for the characterization of patients' pain profile. In contrast to other NeP screening tools, the PD-Q is the only screening tool with weighted sensory descriptors. It is possible that responses to the PD-Q sensory descriptors are influenced by psychological factors, such as catastrophizing or anxiety, which potentially might contribute to an overall higher score of PD-Q and a false positive identification of NeP. This study aimed to explore (i) the relationship between psychological factors (catastrophizing, anxiety, depression and stress) and the total PD-Q score and (ii) if psychological factors are associated with false positive identifications of NeP on the PD-Q compared to clinically diagnosed NeP. Methods The study was a retrospective review of 1,101 patients attending an outpatient pain centre. Patients were asked to complete the PD-Q, the Pain Catastrophizing Scale (PCS), the Depression, Anxiety and Stress Scale (DASS) and the Brief Pain Inventory (BPI). For patients who were identified by PD-Q as having NeP, their medical records were reviewed to establish if they had a clinical diagnosis of NeP. Results Accounting for missing data, complete datasets of 652 patients (mean age 51 (SD14) years, range 18-88; 57% females) were available for analysis. Based on PD-Q scoring, NeP was likely present in 285 (44%) patients. Depression, anxiety, stress, catastrophizing, BPI pain and BPI interference were all significantly related to each other (p < 0.0001) and patients displaying these traits were significantly more likely to have a positive PD-Q score (p < 0.0001). For patients classified by PD-Q as having NeP, only 50% of patients had a clinical diagnosis of NeP. Anxiety was significantly associated with a false positive classification of NeP on PD-Q (p = 0.0036). Conclusions Our retrospective study showed that psychological factors including catastrophizing, depression, anxiety, and stress were all influential in producing a higher score on the PD-Q. We observed a high rate of false positive NeP classification which was associated with the presence of anxiety. Implications Clinicians and researchers should be aware that a patient's psychological state may influence the responses to PD-Q and consequently the final PD-Q score and its NeP classification.

Non-traumatic musculoskeletal pain in Western Australian hospital emergency departments: A clinical audit of the prevalence, management practices and evidence-to-practice gaps.

OBJECTIVES: Musculoskeletal pain (MSP) conditions are a leading cause of morbidity worldwide and a common reason for ED presentation. Little is currently known about non-traumatic MSP (NTMSP) presenting to EDs. The present study described the prevalence and management practices of NTMSP in EDs. METHODS: The design was a retrospective clinical audit in two hospital EDs in Western Australia covering 3 months beginning 1 January 2016. We defined NTMSP as pain of musculoskeletal origin occurring in the absence of external force or excessive physical loading. The outcomes measured included: patient, condition and hospital-episode characteristics, as well as management practices. Management practices were compared to recommended care derived from guideline recommendations. These included: assessment for red flags and psychosocial risk factors, appropriate use of diagnostic imaging, provision of patient education, administration and prescription of analgesic medication, and assessment of risk factors for opioid-related harm. RESULTS: Eight hundred and eighty-eight patients were included in the present study. NTMSP accounted for 3.0% of all ED presentations. According to clinician documentation, red flag and psychosocial assessments were recorded in 73.3 and 10.5% of patients. Forty-one percent of patients were referred for imaging, of which 39.7% were inconsistent with guideline recommendations. Education was recorded 52.0% of the time. At least one opioid medication was administered to 55.3% of patients and there was no documented assessment of risk factors for opioid-related harm. CONCLUSIONS: NTMSP is a relatively common reason for ED presentation. Documented management practices are discordant with guideline recommendations. Strategies to improve the concordance between management and guideline recommendations are needed.

Unmet Needs of Aboriginal Australians With Musculoskeletal Pain: A Mixed-Method Systematic Review.

OBJECTIVE: Musculoskeletal pain (MSP) conditions are the biggest cause of disability, and internationally, indigenous peoples experience a higher burden. There are conflicting reports about Aboriginal Australians and MSP. We conducted a systematic review to describe the prevalence, associated factors, impacts, care access, health care experiences, and factors associated with MSP among Aboriginal Australians. METHODS: We used a systematic search of quantitative and qualitative scientific and grey literature (PROSPERO# CRD42016038342). Articles were appraised using the Mixed Methods Appraisal Tool. Due to study heterogeneity, a narrative synthesis was conducted. RESULTS: Of 536 articles identified, 18 were included (14 quantitative, 4 qualitative), of high (n = 11), medium (n = 2), and low (n = 5) quality. Prevalence of MSP in Aboriginal populations was similar to or slightly higher than the non-Aboriginal population (prevalence rate ratio 1.1 for back pain, 1.2-1.5 for osteoarthritis [OA], and 1.0-2.0 for rheumatoid arthritis). Aboriginal people accessed primary care for knee or hip OA at approximately half the rate of non-Aboriginal people, and were less than half as likely to have knee or hip replacement surgery. Communication difficulties with health practitioners were the main reason why Aboriginal people with MSP choose not to access care. No articles reported interventions. CONCLUSION: Findings provide preliminary evidence of an increased MSP burden among Aboriginal Australians, and particularly for OA, a mismatch between the disease burden and access to health care. To increase accessibility, health services should initially focus on improving Aboriginal patients' experiences of care, in particular by improving patient-practitioner communication. Implications for care and research are outlined.

Concentrations of morphine, morphine-6-glucuronide and morphine-3-glucuronide in serum and cerebrospinal fluid following morphine administration to patients with morphine-resistant pain.

Recent studies have suggested that morphine-3-glucuronide (M3G) may antagonize the analgesic effects of morphine and morphine-6-glucuronide (M6G). To investigate this hypothesis, steady-state concentrations of morphine, M6G and M3G in serum and cerebrospinal fluid (CSF) were measured in 11 patients receiving chronic morphine therapy (9 orally and 2 subcutaneously) for treatment of cancer-related pain. All patients appeared to have morphine-resistant pain and had elected to proceed to intrathecal bupivacaine or percutaneous cordotomy. Morphine, M6G and M3G concentrations were measured by high-performance liquid chromatography. The concentrations (median and range) for morphine, M6G and M3G in serum were 193 (14-1086) nmol/l, 847 (210-4113) nmol/l and 4553 (1324-24035) nmol/l, respectively, while in CSF concentrations of morphine, M6G and M3G were 200 (21-1461) nmol/l, 115 (30-427) nmol/l and 719 (249-3252) nmol/l, respectively. Median molar ratios of M6G/morphine and M3G/morphine in serum were 3.79 and 22.1, respectively, while in CSF the same ratios were 0.42 and 2.39, respectively. Median molar ratios of M3G/M6G in serum and CSF were 5.84 and 6.61, respectively. The median molar ratios for CSF/serum distribution of morphine, M6G and M3G were 1.23, 0.12 and 0.14, respectively. Thus, despite their relatively poor ability to penetrate into the CSF, the high serum concentrations of M6G and M3G resulted in substantial concentrations of these metabolites in the CSF. Nevertheless, M3G/M6G ratios in our morphine-resistant patients were similar to published values in patients with well-controlled pain, suggesting that the hypothesis that M3G plays a major role in morphine-resistance is not correct.

Chronic opioid therapy for chronic non-cancer pain: a review and comparison of treatment guidelines.

BACKGROUND: Long-term opioid use for chronic non-cancer pain has increased substantially in recent years despite the paucity of strong supporting scientific data and concerns regarding adverse effects and potential misuse. STUDY DESIGN: Review and summary of practice guidelines available on PubMed and Cochrane databases as well as on the Internet on chronic opioid therapy from June 2004 to June 2013. OBJECTIVE: To review expert-developed practice guidelines on chronic opioid therapy, published in different countries over the past decade in order to reveal similar principles of therapy and to provide useful information and references for future development of opioid guidelines to identify adequately supported practice points and areas in need of further scientific evidence. METHOD: Seven guidelines were identified as pertaining specifically to the long-term use of opioids for general chronic non-cancer pain from an initial search of the PubMed/Medline and Cochrane databases using combinations of the search terms "opioid," "chronic opioid therapy," "chronic pain," "chronic non-cancer pain," "chronic non-malignant pain," "guidelines," "practice guidelines," and "clinical practice guidelines," filtered to include only articles on humans published in the English language over the past 10 years. RESULTS: All guidelines espouse an individual approach to management, beginning with a comprehensive patient evaluation, with particular focus on eliciting factors that may indicate potential drug misuse and abuse, and a trial of therapy to determine the course of treatment. Goals of treatment should be adequately discussed with and consented to by the patient. Opioids are generally not recommended as first-line therapy but, when used, clinicians should closely monitor patients for loss of response, adverse effects or aberrant behavior, and revise the treatment plan accordingly. Urine drug testing (UDT) may be used as a tool to monitor for aberrant behavior or drug misuse; opioid rotation may be considered when loss of response or adverse effects are a concern, at a starting dose lower than the calculated equianalgesic dose. LIMITATIONS: Information on some African nations, countries in the Middle-East, and Pacific Islands is not available and therefore was not included in this review. CONCLUSION: There is a growing body of scientific evidence to support opioid use in chronic pain. Future work should focus on continuing to generate good-quality evidence on the long-term benefits of opioid therapy, as well as scientific data to guide drug choice and dosing for specific conditions, populations, and situations.

Identification of neuropathic pain in patients with neck/upper limb pain: application of a grading system and screening tools.

The Neuropathic Pain Special Interest Group (NeuPSIG) of the International Association for the Study of Pain has proposed a grading system for the presence of neuropathic pain (NeP) using the following categories: no NeP, possible, probable, or definite NeP. To further evaluate this system, we investigated patients with neck/upper limb pain with a suspected nerve lesion, to explore: (i) the clinical application of this grading system; (ii) the suitability of 2 NeP questionnaires (Leeds Assessment of Neuropathic Symptoms and Signs pain scale [LANSS] and the painDETECT questionnaire [PD-Q]) in identifying NeP in this patient cohort; and (iii) the level of agreement in identifying NeP between the NeuPSIG classification system and 2 NeP questionnaires. Patients (n = 152; age 52 ± 12 years; 53% male) completed the PD-Q and LANSS questionnaire and underwent a comprehensive clinical examination. The NeuPSIG grading system proved feasible for application in this patient cohort, although it required considerable time and expertise. Both questionnaires failed to identify a large number of patients with clinically classified definite NeP (LANSS sensitivity 22%, specificity 88%; PD-Q sensitivity 64%, specificity 62%). These lowered sensitivity scores contrast with those from the original PD-Q and LANSS validation studies and may reflect differences in the clinical characteristics of the study populations. The diagnostic accuracy of LANSS and PD-Q for the identification of NeP in patients with neck/upper limb pain appears limited.

Seeing it helps: movement-related back pain is reduced by visualization of the back during movement.

OBJECTIVES: The aim of this study was to determine whether visualization of the back influenced parameters of movement-related pain in people with chronic nonspecific low back pain. METHODS: We used a randomized cross-over experiment in which 25 participants performed repeated lumbar spine movements under 2 conditions. In the visual feedback condition, patients were able to visualize their back as it moved by the use of mirrors. In the control condition, the mirror was covered so no visualization of the back was possible. RESULTS: The average postmovement pain intensity after participants had moved with visual feedback was less (35.5 ± 22.8 mm) than when they moved without visual feedback (44.7 ± 26.0 mm). This difference was statistically significant (mean difference=9.3, 95% confidence interval: 2.8-15.7 F(1,22)=8.82, P=0.007). The average time to ease after participants had moved with visual feedback was shorter (44.5 s ± 53.8) than when they moved without visual feedback (94.4 s ± 80.7). This difference was also statistically significantly (mean difference=49.9, 95% confidence interval: 19.3-80.6, F(1,22)=8.82, P=0.003). DISCUSSION: Patients with chronic nonspecific low back pain reported less increase in pain and faster resolution of pain when moving in an environment that enabled them to visualize their back. This is consistent with emerging research on the use of mirror visual feedback in other long-standing pain problems and suggests that similar lines of inquiry may be worth pursuing in the chronic nonspecific low back pain population.

Developing recommendations for implementing the Australian Pain Society's pain management strategies in residential aged care.

OBJECTIVE: This study aimed to develop recommendations and a related implementation resource 'toolkit' to facilitate implementation of pain management strategies in Australian Residential Aged Care Facilities (RACFs). METHODS: This qualitative study used written materials, focus groups and individual interviews to gather data from participants. Thirty-four health-care professionals with experience in the aged care sector were recruited from five Western Australian RACFs. General practitioners who had an interest in aged care were contacted via local general practice networks. RESULTS: Findings indicated that focused education sessions were needed to support implementation. A tailored toolkit was developed to assist the process. Funding and workforce constraints were found to be threats to complete implementation in some facilities. CONCLUSIONS: A multifaceted approach is needed to promote the implementation of pain management strategies in RACFs. In particular, unlicensed care workers, who may have responsibility for recognising and reporting signs of pain, require further education to support their role in the pain management process.

Development and testing of a modified version of the brief pain inventory for use in residential aged care facilities.

OBJECTIVES: A two-phase study was conducted to refine a version of Cleeland's Brief Pain Inventory (BPI, Short Form) for use in residential aged care facilities (RACFs). DESIGN: The Australian Pain Society modified Cleeland's BPI by changing numerical response options to word descriptors. In Phase I, this version was tested in RACFs to determine the feasibility of its use, its stability over time, and its internal consistency reliability. Minor modifications resulted. In Phase II, the refined version was abbreviated, and the internal consistency reliability of this Modified Residents' Verbal BPI was examined. SETTING: RACFs. PARTICIPANTS: Thirty-three residents of RACFs in Phase I, 149 in Phase II. INTERVENTION: The study revised and abbreviated the BPI to better fit it for use in RACFs, examining the reliability of the tool. MEASUREMENTS: Mini-Mental State Examination, Global Deterioration Scale, modified BPI. RESULTS: The abbreviated tool comprises three items assessing pain intensity and three assessing pain interference. It also includes an item to specify pain location and a movement protocol. Cronbach alpha coefficient for six intensity and interference items was 0.72 (N=106). CONCLUSION: This abbreviated tool requires further testing but has demonstrated adequate internal consistency reliability and is a brief, multidimensional tool that appears feasible for assessing pain in RACFs, including use with residents who have some cognitive impairment. It shows promise as a screening tool and may be useful to assess the effectiveness of pain relief interventions and to measure pain prevalence.
