Pain assessment: the cornerstone to optimal pain management

The effects of a sugar-free amino acid-containing electrolyte beverage on 5-kilometer performance, blood electrolytes, and post-exercise cramping versus a conventional carbohydrate-electrolyte sports beverage and water

OBJECTIVE

The purpose of this study was to examine the acute effects of a multi-ingredient, low calorie dietary supplement (MIDS, XTEND® Healthy Hydration) on 5-kilometer (5-km) time trial performance and blood electrolyte concentrations compared to a carbohydrate-electrolyte beverage (CE, GATORADE® Thirst Quencher) and distilled water (W).

METHODS

During visit 1 (V1), participants (10 men and 10 women, 20-35 years old, BMI ≤ 29 kg/m2, recreationally active) reported to the laboratory whereby the following tests were performed: i) height and weight measurements, ii) body composition analysis, iii) treadmill testing to measure maximal aerobic capacity, and iv) 5-km time trial familiarization. The second visit (V2) was one week after V1 in the morning (0600 - 0900) and participants arrived 12-14 h fasted (no food or drink). The first battery of assessments (V2-T1) included nude body mass, urine specific gravity (USG), a profile of mood states (POMS) questionnaire, and the completion of a visual analogue scale (VAS) questionnaire to quantify cramping. Then heart rate (HR), blood pressure (BP), total body hydration (via bioelectrical impedance spectroscopy [BIS]) were examined. Finally, a measurement of blood markers via finger stick was performed. Participants consumed a randomized beverage (16 fl. oz. of MIDS, 16 fl. oz. of W, or 16 fl. oz. of CE) within 3 min followed by a 45-min rest. Following the rest period, a second battery (V2-T2) was performed whereby participants' USG was assessed and they completed the POMS and VAS questionnaires, and HR, BP, and blood markers were measured. The participants then performed a 5-km treadmill time trial. Immediately following the 5-km time trial, participants completed a third testing battery (V2-T3) that began with blood markers, HR and BP assessments, followed by nude body weight assessment, and the POMS and VAS questionnaires. After 60 min, a fourth battery (V2-T4) was performed that included HR, BP, and blood markers. After sitting quietly for another 60 min a fifth battery assessment was performed (V2-T5) that included participants' USG, POMS and VAS questionnaires, HR, BP, blood markers, and total body hydration. Visits 3 (V3) and 4 (V4) followed the same protocol except a different randomized drink (16 oz. of CE, MIDS, or W) was consumed; all of which were separated by approximately one week.

RESULTS

No differences occurred between conditions for 5-km time trial completion, indirect calorimetry outcomes during 5-km time trials, USG, or nude mass measurements (p > 0.05 for all relevant statistical tests). However, blood potassium and the sodium/potassium ratio displayed significant interactions (p < 0.05), and post hoc testing indicated these values were better maintained in the MIDS versus other conditions. Post-exercise cramp prevalence was greater in the CE (p < 0.05) and trended higher with W (p = 0.083) compared to the MIDS condition. Post-exercise cramp severity was also elevated with the W and CE beverages (p < 0.05) but not the MIDS (p = 0.211).

CONCLUSIONS

The MIDS did not affect 5-km time trial performance but exhibited favorable effects on blood electrolyte and post-exercise self-reporting cramp outcomes compared to the CE and W drinks.

Assessment and management patterns for chronic musculoskeletal pain in the family practice setting

BACKGROUND

Chronic pain affects 11% of the US population. Most patients who experience pain, particularly chronic musculoskeletal pain, seek care in primary care settings. Assessment of the patient pain experience is the cornerstone to optimal pain management; however, pain assessment remains a challenge for medical professionals. It is unknown to what extent the assessment of pain intensity is considered in context of function and quality of life.

OBJECTIVE

To understand common practices related to assessment of pain and function in patients with chronic musculoskeletal disorders.

DESIGN

Cross-sectional survey.

METHODS

A 42-item electronic survey was developed with self-reported numeric ratings and responses related to knowledge, beliefs, and current practices. All physicians and non-physician clinicians affiliated with the AAFP NRN and 2000 AAFP physician members were invited to participate.

RESULTS/FINDINGS

Primary care clinicians report that chronic joint pain assessment should be comprehensive, citing assessment elements that align with the comprehensive pain assessment models. Pain intensity remains the primary focus of pain assessment in chronic joint pain and the most important factor in guiding treatment decisions, despite well-known limitations. Clinicians also report that patients with osteoarthritis should be treated by Family Medicine.

CONCLUSIONS

Pain assessment is primarily limited to pain intensity scales which may contribute to worse patient outcomes. Given that most respondents believe primary care/family medicine should be primary responsible for the care of patients with osteoarthritis, awareness of and comfort with existing guidelines, validated assessment instruments and the comprehensive pain assessment models could contribute to delivery of more comprehensive care.

Effect of Educational Interventions for Improving the Nurses' Knowledge, Attitude, and Practice of Pediatric Pain Management: A Aystematic Review and Meta-Analysis

OBJECTIVE

This study aimed to evaluate the effectiveness of educational interventions in improving nurses' knowledge, attitude, and practice regarding pediatric pain management.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

A comprehensive search was conducted in MEDLINE, Scopus, Cochrane database, Google Scholar, and trial registries, supplemented by bibliography searches.

REVIEW/ANALYSIS METHODS

This review included randomized controlled trials, nonrandomized trials, and quasi-experimental trials with control groups. Eligible studies involved nurses (professionals or students) caring for pediatric patients and featured any form of educational intervention for pain management. Pooled effect estimates were calculated using a random effects model, and heterogeneity was assessed using the I-squared statistic.

RESULTS

The pooled results demonstrated a significant improvement in nurses' knowledge and attitudes toward pediatric pain management postintervention, with a Standardized Mean Difference (SMD) of 2.41 (95% CI: 0.58-4.23). Additionally, the pooled results indicated a higher likelihood of effective pain medication administration (OR = 1.98; 95% CI: 1.21-3.27). However, there was no significant difference in the utilization of pain assessment tools (OR = 19.85; 95% CI: 0.29-1352.98). Pooled OR was 3.42 (95% CI: 1.93-6.07), showing significantly higher odds of ability to administer nonpharmacological interventions. Sensitivity analyses confirmed the robustness of these findings.

CONCLUSIONS

Educational interventions significantly improve nurses' knowledge, attitudes, and ability to administer both pharmacological and nonpharmacological pediatric pain management interventions.

Nociceptive and Transcriptomic Responses in a Swine Diabetic Wound Model Treated With a Topical Angiotensin 1 Receptor Antagonist

BACKGROUND

Painful, treatment-resistant wounds are prevalent among diabetic patients and significantly affect health-related quality of life (HRQOL). Topical treatments may help alleviate pain without risk of dependence or side effects. However, there is a lack of topical wound compounds targeting pain-specific receptors. One possible target is proinflammatory angiotensin 1 receptor (AT1R), which is upregulated in diabetic skin and has been implicated in nociception.

OBJECTIVES

We investigated the effects of topical valsartan, an AT1R antagonist, on pain (nociceptive thresholds) and gene expression changes (transcriptomics) in a swine model of diabetic wounds.

METHODS

Eight wounds were surgically induced in diabetic, hyperglycemic Yucatan miniature swine ( n = 4). Topical AT1R antagonist was applied to wounds on one side and vehicle on the other side. Nocifensive testing was conducted at baseline and then weekly, beginning 7 days after wound induction. Mechanical and thermal stimuli were applied to the wound margins until a nocifensive reaction was elicited or a predetermined cutoff was reached. After 7 weeks of testing, tissue from the dorsal horn, dorsal root ganglion, and wounds were sequenced and analyzed with DESeq2. Unbiased pathway analyses using Metascape were conducted on differentially expressed genes.

RESULTS

There was no significant difference in mechanical tolerance threshold between AT1R antagonist-treated and vehicle-treated wounds ( p = .106). Thermal tolerance was significantly higher in AT1R antagonist-treated wounds compared to vehicle-treated ( p = .015). Analysis of differentially expressed genes revealed enriched pathways of interest: interleukin-18 signaling in dorsal horn laminae IV-V and sensory perception of mechanical stimulus in wound tissue.

DISCUSSION

In this study, wounds modeling diabetic ulcers were created in hyperglycemic swine and treated with a topical AT1R antagonist. AT1R-antagonist-treated wounds had a higher tolerance threshold than vehicle-treated wounds for thermal hyperalgesia, but not mechanical allodynia. Pathway analyses of differentially expressed genes revealed several pathways of interest for future pain research. Although further studies are needed to confirm the findings, this study can improve nursing care by providing information about a potential future treatment that may be used to decrease pain and improve HRQOL in patients with diabetic wounds.

Comparison of Machine Leaning Models for Prediction of Acute Pain Severity and On-Treatment Opioid Utilization in Oral Cavity and Oropharyngeal Cancer Patients Receiving Radiation Therapy: Exploratory Analysis from a Large-Scale Retrospective Cohort

Background

Acute pain is a common and debilitating symptom experienced by oral cavity and oropharyngeal cancer (OC/OPC) patients undergoing radiation therapy (RT). Uncontrolled pain can result in opioid overuse and increased risks of long-term opioid dependence. The specific aim of this exploratory analysis was the prediction of severe acute pain and opioid use in the acute on-treatment setting, to develop risk-stratification models for pragmatic clinical trials.

Materials and Methods

A retrospective study was conducted on 900 OC/OPC patients treated with RT during 2017 to 2023. Clinical data including demographics, tumor data, pain scores and medication data were extracted from patient records. On-treatment pain intensity scores were assessed using a numeric rating scale (0-none, 10-worst) and total opioid doses were calculated using morphine equivalent daily dose (MEDD) conversion factors. Analgesics efficacy was assessed based on the combined pain intensity and the total required MEDD. ML models, including Logistic Regression (LR), Support Vector Machine (SVM), Random Forest (RF), and Gradient Boosting Model (GBM) were developed and validated using ten-fold cross-validation. Performance of models were evaluated using discrimination and calibration metrics. Feature importance was investigated using bootstrap and permutation techniques.

Results

For predicting acute pain intensity, the GBM demonstrated superior area under the receiver operating curve (AUC) (0.71), recall (0.39), and F1 score (0.48). For predicting the total MEDD, LR outperformed other models in the AUC (0.67). For predicting the analgesics efficacy, SVM achieved the highest specificity (0.97), and best calibration (ECE of 0.06), while RF and GBM achieved the same highest AUC, 0.68. RF model emerged as the best calibrated model with ECE of 0.02 for pain intensity prediction and 0.05 for MEDD prediction. Baseline pain scores and vital signs demonstrated the most contributed features for the different predictive models.

Conclusion

These ML models are promising in predicting end-of-treatment acute pain and opioid requirements and analgesics efficacy in OC/OPC patients undergoing RT. Baseline pain score, vital sign changes were identified as crucial predictors. Implementation of these models in clinical practice could facilitate early risk stratification and personalized pain management. Prospective multicentric studies and external validation are essential for further refinement and generalizability.

Pharmacological Prescribing and Satisfaction with Pain Treatment Among Non-Hispanic Black Men with Chronic Pain

Introduction

Pharmacological strategies are often central to chronic pain management; however, pain treatment among non-Hispanic Black men may differ because of their disease profiles and healthcare interactions. However, less is known about pain medication prescribing and patients' satisfaction with pain treatment and management among non-Hispanic Black men with self-reported chronic pain.

Purpose

This study assessed factors associated with non-Hispanic Black men being prescribed/recommended narcotics/opioids for chronic pain and their satisfaction with pain treatment/management.

Methods

Data were analyzed from 286 non-Hispanic Black men with chronic pain who completed an internet-delivered questionnaire. Participants were recruited nationwide using a Qualtrics web-based panel. Logistic regression was used to identify factors associated with being prescribed/recommended narcotics/opioids for pain management treatment. Then, ordinary least squares regression was used to identify factors associated with their satisfaction level with the pain treatment/management received.

Results

On average, participants were 56.2 years old and 48.3% were prescribed/recommended narcotics/opioids for chronic pain. Men with more chronic conditions (Odds Ratio [OR] = 0.57, P = 0.043) and depression/anxiety disorders (OR = 0.53, P = 0.029) were less likely to be prescribed/recommended narcotics/opioids. Men who were more educated (OR = 2.09, P = 0.044), reported more frequent chronic pain (OR = 1.28, P = 0.007), and were allowed to participate more in decisions about their pain treatment/management (OR = 1.11, P = 0.029) were more likely to be prescribed/recommended narcotics/opioids. On average, men with more frequent chronic pain (B = -0.25, P = 0.015) and pain problems (B = -0.16, P = 0.009) were less satisfied with their pain treatment/management. Men who were allowed to participate more in decisions about their pain treatment/management reported higher satisfaction with their pain treatment/management (B = 0.55, P < 0.001).

Conclusion

Playing an active role in pain management can improve non-Hispanic Black men's satisfaction with pain treatment/management. This study illustrates the importance of patient-centered approaches and inclusive patient-provider interactions to improve chronic pain management.

Pain and Its Association with Survival for Black and White Individuals with Advanced Prostate Cancer in the United States

Bone pain is a well-known quality-of-life detriment for individuals with prostate cancer and is associated with survival. This study expands previous work into racial differences in multiple patient-reported dimensions of pain and the association between baseline and longitudinal pain and mortality. This is a prospective cohort study of individuals with newly diagnosed advanced prostate cancer enrolled in the International Registry for Men with Advanced Prostate Cancer (IRONMAN) from 2017 to 2023 at U.S. sites. Differences in four pain scores at study enrollment by race were investigated. Cox proportional hazards models and joint longitudinal survival models were fit for each of the scale scores to estimate HRs and 95% confidence intervals (CI) for the association with all-cause mortality. The cohort included 879 individuals (20% self-identifying as Black) enrolled at 38 U.S. sites. Black participants had worse pain at baseline compared with White participants, most notably a higher average pain rating (mean 3.1 vs. 2.2 on a 10-point scale). For each pain scale, higher pain was associated with higher mortality after adjusting for measures of disease burden, particularly for severe bone pain compared with no pain (HR, 2.47; 95% CI: 1.44-4.22). The association between pain and all-cause mortality was stronger for participants with castration-resistant prostate cancer compared with those with metastatic hormone-sensitive prostate cancer and was similar among Black and White participants. Overall, Black participants reported worse pain than White participants, and more severe pain was associated with higher mortality independent of clinical covariates for all pain scales.

SIGNIFICANCE

Black participants with advanced prostate cancer reported worse pain than White participants, and more pain was associated with worse survival. More holistic clinical assessments of pain in this population are needed to determine the factors upon which to intervene to improve quality of life and survivorship, particularly for Black individuals.

Exploring the Impact of Occupational Adaptation-Focused Interventions on Music Student Health

Music students are at an elevated risk of playing-related musculoskeletal disorders. This study aimed to explore the impact of occupational adaptation-focused interventions on music student health. A quasi-experimental one-group pretest/posttest design was used. Music students received occupational therapy services grounded in the Occupational Adaptation model of practice. Assessment tools included the Performing Arts Module of the Disabilities of the Arm, Shoulder, and Hand (DASH) and an occupational adaptive process evaluation. Twelve music students, ages 19 to 32 years old, participated in this study. Results indicated a significant decrease in current pain intensity (Z = -2.038, p < .042), 24-hr pain intensity (Z = -2.94, p < .003), and DASH scores (Z = -2.81, p < .005). Strong correlations were found between participants' adaptive capacity and improved DASH scores and 24-hr pain. Occupational adaptation-focused interventions can improve university-level music student health by addressing body functions affecting music performance and increasing their adaptive capacity.

Determining a cut-off point for intervention analgesia in rabbits using the Bristol Rabbit Pain Scale

BACKGROUND

The objective of this study was to determine the threshold of the Bristol Rabbit Pain Scale (BRPS) indicating the need for intervention analgesia.

METHODS

Fourteen members of veterinary staff were recruited to rate rabbits (n = 71) in acute pain. Observers in group A (n = 7) were asked to score each rabbit using the BRPS, while observers in group B (n = 7) independently answered the question 'In your clinical capacity, do you think this animal requires analgesia?' with either 'Yes' or 'No'. The answers from the two groups were then compared.

RESULTS

Rabbits for which group B answered 'No' (n = 36) had a median BRPS score (range) of 4 (0-10), while those for which group B answered 'Yes' (n = 42) had a median BRPS score of 9 (1-18; Z = -7.48; p < 0.001). The area under the receiver operating characteristic curve was 0.85 (95% confidence interval: 0.77-0.93; p < 0.001), indicating excellent discrimination of the BRPS with a cut-off score of 5.5 (sensitivity 88.1% and specificity 69.4%). However, for practicality, a score of 5 was deemed a feasible cut-off.

LIMITATIONS

The main limitations of this study are the small rabbit sample size and the subjective nature of pain scoring in animals.

CONCLUSIONS

Analgesic intervention should be considered in rabbits with a pain score equal to or greater than 5 on the BRPS.

Content of clinicians' communication with patients suffering from spinal pain in assessment situations in a specialized spine center: A qualitative study evaluating psychologically informed pain assessments before and after clinicians' participation in an Acceptance and Commitment Therapy course

INTRODUCTION

Assessment is an important part of chronic pain rehabilitation and should be conducted in line with the current biopsychosocial conceptualization of pain to capture the subjectivity and context of pain. However, pain assessment is commonly conducted from a biomedical framework. A course in Acceptance and Commitment Therapy (ACT) was provided to spinal pain clinicians as a framework to promote more person-centered and psychosocially focused assessments and related psychologically informed practices. The purpose of this qualitative study was to explore the verbal content of clinicians' communication with patients experiencing spinal pain in assessment situations before and after clinicians participated in an ACT course.

METHODS

Pain assessments of patients with chronic low back pain conducted by six spinal pain clinicians from different professions were audio-recorded and transcribed. This was done before and after participation in an eight-day ACT course with four following supervisions. A thematic analysis was carried out by two authors across all material, and a comparison of the applied number of codes pre-course and post-course was carried out as an indicator of change.

RESULTS

Data consisted of transcripts from the six clinicians across 23 different patients (12 before course participation). Through analysis, 11 codes were developed, which were clustered in three overarching themes: Psychological domains, Communication Techniques, and Intervention Elements. Overall, there was an increase in the application of many of the codes in the transcripts from pre-course to post-course, however with large differences across codes. Increases were primary related to the discussion of life values and value-based action and quality of life as well as the employment of mirroring, challenging beliefs and assumptions, and addressing coping and pacing.

CONCLUSIONS

While not the case for all factors, the present findings indicate an increase in including psychological factors and employing interpersonal communication skills after a course in ACT. However, it remains unknown due to the design if the changes reported in this study reflect a clinically valuable change and whether they are due to the ACT training itself. Future research will improve our understanding of the effectiveness of this type of intervention in assessment practices.

Pain assessment 3 × 3: a clinical reasoning framework for healthcare professionals

OBJECTIVES

To give an overview of central aspects of pain medicine-specific clinical reasoning when assessing a pain patient. Clinical reasoning is the thinking and decision-making processes associated with clinical practice.

METHODS

Three core pain assessment areas that are crucial for clinical reasoning in the field of pain medicine are discussed, each of them consisting of three points.

RESULTS

First, it is important to distinguish acute, chronic non-cancer, and cancer-related pain conditions. This classical and very simple trichotomy still has important implications treatment-wise, e.g., concerning the use of opioids. Second, the pain mechanism needs to be assessed. Is the pain nociceptive, neuropathic, or nociplastic? Simply put, nociceptive pain has to do with injury of non-neural tissue, neuropathic pain is caused by a disease or lesion of the somatosensory nervous system, and nociplastic pain is believed to be related to a sensitized nervous system (c.f. the concept of "central sensitization"). This also has implications concerning treatment. Some chronic pain conditions are nowadays viewed more as diseases rather than the pain being merely a symptom. In the new ICD-11 pain classification, this is conceptualized by the characterization of some chronic pains as "primary". Third, in addition to a conventional biomedical evaluation, psychosocial and behavioral aspects must also be assessed, the pain patient being viewed as an active agent and not merely as the passive recipient of an intervention. Hence, the importance of a dynamic bio-psycho-social perspective. The dynamic interplay of biological, psychological, and social aspects must be taken into account, putative behavioral "vicious circles" thereby being identified. Some core psycho-social concepts in pain medicine are mentioned.

CONCLUSIONS

The clinical applicability and clinical reasoning power of the 3 × 3 framework is illustrated by three short (albeit fictional) case descriptions.

Investigation of a Novel Activity-Based Checks (ABC) Functional Pain Scale in the Post-Operative Urologic Surgery Patient

Introduction

The authors investigated a novel functional pain scale, the Activity-Based Checks (ABCs) of Pain, following open urologic surgery. The primary objectives were to establish the strength of the correlation between the ABCs and the numeric rating scale (NRS) and determine the impact of functional pain on the patient's opioid requirements. We hypothesized that ABC score would correlate strongly with NRS and that the ABC score during hospitalization would be more closely correlated with the number of opioids prescribed and used.

Methods

This prospective study included patients at a tertiary academic hospital undergoing nephrectomy and cystectomy. The NRS and ABCs were collected pre-operatively, during the inpatient stay, and at the one-week follow-up. Milligrams of morphine equivalents (MMEs) prescribed at discharge and the MME reportedly taken during the first post-operative week were recorded. Spearman's Rho was used to assess the correlation between scale variables.

Results

Fifty-seven patients were enrolled. The ABCs correlated strongly with the NRS at baseline and post-operative appointments (r = 0.716, p < 0.001 and 0.643, p < 0.001). Neither the NRS nor the composite ABCs score was predictive of outpatient MME requirements; the ABCs function, "Walking outside the room" significantly correlated to MMEs taken after discharge (r = 0.471, p = 0.011). The greatest predictor of MMEs taken was the number of MMEs prescribed (0.493, p = 0.001).

Conclusions

This study highlighted the importance of post-operative pain assessment that takes functional pain into consideration to evaluate pain, inform management decisions, and reduce opiate reliance. It also emphasized the strong relationship between opioids prescribed and opioids consumed.

Feasibility and Acceptability of the Pain Profile, a Clinical Questionnaire Aimed at Improving Pain Care

Purpose

Despite being one of the most common medical complaints, chronic pain is difficult to manage due to ineffective communication between providers and patients and time restraints during appointments. Patient-centered questionnaires have the potential to optimize communication by assessing a patient's pain history, prior treatments, and associated comorbidities to develop an effective treatment plan. This study aimed to analyze the feasibility and acceptability of a pre-visit clinical questionnaire aimed at improving communication and pain care.

Patients and Methods

The "Pain Profile" questionnaire was piloted across two specialty pain clinics in a large academic medical center. Patient and provider surveys were conducted with patients who completed the Pain Profile questionnaire and providers who use it in practice. Surveys consisted of multiple-choice and open-ended questions regarding the helpfulness, usability, and implementation of the questionnaire. Descriptive analyses of patient and provider surveys were conducted. Qualitative data were analyzed using matrix framework-based coding.

Results

A total of 171 patients and 32 clinical providers completed the feasibility and acceptability surveys. 77% of patients (N= 131) found the Pain Profile helpful in communicating their pain experiences and 69% of providers (N= 22) found it helpful in guiding clinical decisions. The section that assessed the impact of pain was rated most helpful by patients (4/5) while the open-ended section asking patients to describe their pain history was rated least helpful by patients and providers (3.7/5 and 4.1/5, respectively). Both patients and providers provided suggestions to future iterations of the Pain Profile, including the addition of opioid risk and mental health screening tools.

Conclusion

The Pain Profile questionnaire was feasible and acceptable in a pilot study at a large academic site. Future testing in a large-scale, fully powered trial is needed to assess the effectiveness of the Pain Profile in optimizing communication and pain management.

Feasibility and acceptability to use a smartphone-based manikin for daily longitudinal self-reporting of chronic pain

Background

As management of chronic pain continues to be suboptimal, there is a need for tools that support frequent, longitudinal pain self-reporting to improve our understanding of pain. This study aimed to assess the feasibility and acceptability of daily pain self-reporting using a smartphone-based pain manikin.

Methods

For this prospective feasibility study, we recruited adults with lived experience of painful musculoskeletal condition. They were asked to complete daily pain self-reports via an app for 30 days. We assessed feasibility by calculating pain report completion levels, and investigated differences in completion levels between subgroups. We assessed acceptability via an end-of-study questionnaire, which we analysed descriptively.

Results

Of the 104 participants, the majority were female (n = 87; 84%), aged 45-64 (n = 59; 57%), and of white ethnic background (n = 89; 86%). The mean completion levels was 21 (± 7.7) pain self-reports. People who were not working (odds ratio (OR) = 1.84; 95% confidence interval (CI), 1.52-2.23) were more likely, and people living in less deprived areas (OR = 0.77; 95% CI, 0.62-0.97) and of non-white ethnicity (OR = 0.45; 95% CI, 0.36-0.57) were less likely to complete pain self-reports than their employed, more deprived and white counterparts, respectively. Of the 96 participants completing the end-of-study questionnaire, almost all participants agreed that it was easy to complete a pain drawing (n = 89; 93%).

Conclusion

It is feasible and acceptable to self-report pain using a smartphone-based manikin over a month. For its wider adoption for pain self-reporting, the feasibility and acceptability should be further explored among people with diverse socio-economic and ethnic backgrounds.

Assessment of the Community Pharmacists' Knowledge and Attitudes Toward Pain and Pain Management in Saudi Arabia

Background

Pain is a global health issue that affects an individual's quality of life. Its alleviation and management will enhance patients' experience. Community pharmacists can help manage pain severity through their valuable roles in medical teams and by managing the consequences of pain.

Objective

This study aimed to evaluate community pharmacists' knowledge and attitudes toward pain and pain management in Saudi Arabia.

Methods

A cross-sectional study was performed to evaluate community pharmacists' knowledge and attitudes toward pain and pain management in Saudi Arabia. Pharmacists aged ≥ 21 years, with a degree in pharmacy were included in this study. Each respondent participated in an online survey covering cancer-oriented pain and assessment of pain; pharmacology; abuse of substances; and physical dependence. An independent t-test and One-way ANOVA, with least significant difference as a post-hoc test, were employed, in addition to the General Linear Regression Model using Main Effect as the model.

Results

This study revealed that the pain-related knowledge and attitude among community pharmacists in Saudi Arabia were inadequate. Age (p = 0.003), work experience (p = 0.036), nature of work (p = 0.001), and work location (p = 0.003) were determined as significant factors affecting their overall knowledge and attitude toward pain.

Conclusion

Overall, attempts to expand community pharmacists' knowledge and foster an appropriate attitude toward pain management among them in Saudi Arabia are highly recommended. Additional academic courses, studies, and tailored neuroscience courses will improve their awareness and knowledge of pain and pain management.

Patient-reported outcome measures for pain in women with pelvic floor disorders: a systematic review

INTRODUCTION AND HYPOTHESIS

Patient-reported outcome measures (PROMs) are helpful instruments when measuring and reporting changes in patient health status (Al Sayah et al. J Patient Rep Outcomes 5 (Suppl 2):99, 2021) such as the health-related quality of life (HrQoL) of women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The Australasian Pelvic Floor Procedure Registry (APFPR) aims to increase capacity for women to report surgical outcomes through the collection of HrQoL data (Ruseckaite et al. Qual Life Res. 2021) but currently lacks a pain-specific PROM for women with pelvic floor disorders (PFDs), particularly POP and SUI. This review aims to systematically review the existing literature and identify instruments that measure pain in women with POP and SUI for inclusion within the APFPR, which reports on complications from these conditions.

METHODS

We conducted a literature search on OVID MEDLINE, Embase, CINAHL, PsycINFO and EMCARE databases in addition to Google Scholar and grey literature to identify studies from inception to April 2021. Full-text studies were included if they used PROMs to measure pain in women with POP and SUI. Two authors independently screened articles, extracted data and assessed methodological quality.

RESULTS

From 2001 studies, 23 publications describing 19 different PROMs were included for analysis. Eight of these instruments were specific to the pelvic floor; four were only specific to pain and used across multiple disorders; three were generic quality of life instruments and four were other non-validated instruments such as focus group interviews. These instruments were not specific to pain in women with POP or SUI, as they did not identify all relevant domains such as the sensation, region and duration of pain, or incidents where onset of pain occurs.

CONCLUSIONS

The findings of this review suggest there are no current PROMs that are suitable pain-specific instruments for women with POP or SUI. This knowledge may inform and assist in the development of a new PROM to be implemented into the APFPR.

Assessment, pharmacological therapy and rehabilitation management of musculoskeletal pain in children with mucopolysaccharidoses: a scoping review

Background

Pain of musculoskeletal origin is very common in young patients affected by Mucopolysaccharidoses. This scoping review evaluates the evidence for assessment, pharmacological treatment and rehabilitation management for musculoskeletal pain of the latter.

Methods

A Medline search through PubMed has been performed for studies published in English at least for the past twenty years. Two investigators independently reviewed all search results and extracted those that met the inclusion criteria.

Results

29 studies have been selected and analysed in depth, of which 10 related to pain assessment, 11 concerned pharmacological approach, and 8 reported rehabilitation approaches.

Conclusion

Few data are available in literature concerning the classification and management of pain in children with Mucopolysaccharidoses. Notwithstanding, pain evaluation methods are effectively used to classify pain intensity, according to the age group and communication abilities of young Mucopolysaccharidoses patients. The review emphasizes that drug therapies have a palliative purpose, while rehabilitation reduces musculoskeletal pain and can provide a therapeutic effect on disabilities.

Pain assessment practice and associated factors among nurses working at adult care units in public hospitals in Wolaita Zone, Southern Ethiopia, 2021

Background

Using standard pain assessment techniques is a cornerstone for effective pain management. Pain is not assessed in a standardized manner in numerous practice settings. The problem of applying pain assessment principles was found to be higher in low-income countries. Very limited evidence indicates the standard of pain assessment practice among nurses in Ethiopia. Therefore, the purpose of this study was to identify pain assessment practice and associated factors among nurses working at adult care units in public hospitals in the Wolaita Zone, Southern Ethiopia.

Methods

A cross-sectional study was conducted among 290 nurses working at adult care units in public hospitals in Wolaita zone. Data were collected from February to March 2021. A structured self-administered questionnaire was used for data collection. Epi Data 4.6 was used to enter the data, and SPSS version 26 was used to analyze the data. A logistic regression model was used, and statistical significance was declared at P ≤ 0.05. An adjusted odds ratio with 95%CI was used to measure the degree of association.

Results

A total of 267 nurses participated in the study, giving a response rate of 97.8%. Almost three-fourths (73.8%) of the study nurses reported that they assessed pain for their patients. Only 23.6% of the study nurses discussed pain assessment scores during a nurse-to-nurse report. Below, half (47.2%) of the study participants documented pain assessment scores. The proportion of nurses with good pain assessment practice was found to be 38.2%.

The odds of having good pain assessment practice among nurses who received training on pain management was two times higher than its counterpart. The nurses who perceived organizational support were twice more likely to have good pain assessment practice than their counterparts.

Conclusion

Nurses’ pain assessment practice was found to be low. Moreover, a substantial proportion of the study nurses did not discuss pain assessment scores during a nurse-to-nurse report with low documentation practice. Continuous professional development through in-service training and education is crucial to the improvement of nurses’ pain assessment practice. Furthermore, ameliorating organizational support by means of a supportive working environment is suggested to the betterment of nurses’ assessment practice.

Acupuncture in the emergency department for pain management: A BraveNet multi-center feasibility study

PURPOSE

Pain accounts for up to 78% of emergency department (ED) patient visits and opioids remain a primary method of treatment despite risks of addiction and adverse effects. While prior acupuncture studies are promising as an alternative opioid-sparing approach to pain reduction, successful conduct of a multi-center pilot study is needed to prepare for a future definitive randomized control trial (RCT).

METHODS

Acupuncture in the Emergency Department for Pain Management (ACUITY) is funded by the National Center for Complementary and Integrative Health. The objectives are to: conduct a multi-center feasibility RCT, examine feasibility of data collection, develop/deploy a manualized acupuncture intervention and assess feasibility/implementation (barrier/facilitators) in 3 EDs affiliated with the BraveNet Practice Based Research Network.Adults presenting to a recruiting ED with acute non-emergent pain (e.g., musculoskeletal, back, pelvic, noncardiac chest, abdominal, flank or head) of ≥4 on a 0-10-point Numeric Rating Scale will be eligible. ED participants (n = 165) will be equally randomized to Acupuncture or Usual Care.At pre-, post-, and discharge time-points, patients will self-assess pain and anxiety using the Numeric Rating Scale. Pain, anxiety, post-ED opioid use and adverse events will be assessed at 1 and 4 weeks. Opioid utilization in the ED and discharge prescriptions will be extracted from patients' electronic medical records.Acupuncture recipients will asked to participate in a brief qualitative interview about 3 weeks after their discharge. ED providers and staff will also be interviewed about their general perspectives/experiences related to acupuncture in the ED and implementation of acupuncture in ACUITY.

RESULTS

Recruitment began on 5/3/21. As of 12/7/21: 84 patients have enrolled, the responsive acupuncture intervention has been developed and deployed, and 26 qualitative interviews have been conducted.

CONCLUSION

Successful conduct of ACUITY will provide the necessary framework for conducting a future, multi-center, definitive RCT of acupuncture in the ED.

Postoperative Pain After Endoscopic vs Microscopic Otologic Surgery: A Systematic Review and Meta-analysis

OBJECTIVE

Equivalent outcomes, such as procedural safety and audiometry, have been reported between endoscopic ear surgery (EES) and microscopic ear surgery (MES). This study aims to determine if EES leads to decreased postoperative pain when compared with MES.

DATA SOURCES

PubMed, OVID MEDLINE, Scopus, Web of Science, and Cochrane Central from 2000 to 2020.

REVIEW METHODS

A systematic review in accordance with the PRISMA guidelines and standardized bias assessment was performed. Studies containing original data on postoperative pain following EES and MES were included.

RESULTS

Fourteen studies fulfilled eligibility: 7 retrospective studies, 6 randomized controlled trials, and 1 case series. Studies included surgery for cholesteatoma (n = 3), tympanoplasty/myringoplasty (n = 6), and stapedotomy (n = 5), pooling data from 974 patients. Postoperative pain was quantitatively described through a variety of numeric pain scores. Meta-analysis was performed on 11 studies. Among the 7 studies utilizing the numeric rating scale or visual analog scale, postoperative pain in the EES cohort was significantly lower than that of the MES cohort (standardized mean difference = -1.45 [95% CI, -2.05 to -0.85], P < .001). Similarly, pain scores were lower in the EES cohort among the 4 studies utilizing the Three Grades Pain Scale (odds ratio = 0.2 [95% CI, 0.09-0.45], P < .001). Additional qualitative strengths identified in EES included significant improvements in visualization, operative time, postoperative complications, and decreased need for canalplasty. Quality assessment indicated low to moderate risk of bias for all studies.

CONCLUSION

Meta-analysis confirms that EES results in significantly less postoperative pain when compared with MES. This surgical approach should be considered in the armamentarium of otologic surgeons, allowing for improved outcomes.

Evaluation of the Pain Impact Index for Community-Dwelling Older Adults Through the Application of Rasch Modelling

OBJECTIVE

Evaluate the Pain Impact Index, a simple, brief, easy-to-use, and novel tool to assess the impact of chronic pain in community-dwelling older adults.

METHODS

A Rasch modelling analysis was undertaken in Stata using a partial credit model suited to the Likert-type items that comprised the Index. The Index was evaluated for ordering of category thresholds, unidimensionality, overall fit to the Rasch model, measurement bias (Differential Item Functioning, DIF), targeting, and construct validity.

RESULTS

The four-item Pain Impact Index was self-completed by 6454 community-dwelling Australians who were aged at least 70 years and experienced pain on most days. Two items showed evidence of threshold disordering, and this was resolved by collapsing response categories (from 5 to 3) for all items. The rescored Index conformed to the unidimensionality assumption and had satisfactory fit with the Rasch model (analyses conducted on a reduced sample size to mitigate the potential for overpowering: n = 377, P > 0.0125, power > 77%). When considering uniform DIF, the most frequent sources of measurement bias were age, knee pain, and upper back pain. When considering nonuniform DIF, the most frequent source of measurement bias was knee pain. The Index had good ability to differentiate between respondents with different levels of pain impact and had highest measurement precision for respondents located around the average level of pain impact in the study sample. Both convergent and discriminant validity of the Index were supported.

CONCLUSION

The Pain Impact Index showed evidence of unidimensionality, was able to successfully differentiate between levels of pain impact, and had good evidence of construct validity.

Quantitative Sensory Testing to Predict Postoperative Pain

Purpose of Review

We review the relevance of quantitative sensory testing (QST) in light of acute and chronic postoperative pain and associated challenges.

Recent Findings

Predicting the occurrence of acute and chronic postoperative pain with QST can help identify patients at risk and allows proactive preventive management. Generally, central QST testing, such as temporal summation of pain (TSP) and conditioned pain modulation (CPM), appear to be the most promising modalities for reliable prediction of postoperative pain by QST. Overall, QST testing has the best predictive value in patients undergoing orthopedic procedures.

Summary

Current evidence underlines the potential of preoperative QST to predict postoperative pain in patients undergoing elective surgery. Implementing QST in routine preoperative screening can help advancing traditional pain therapy toward personalized perioperative pain medicine.

Pain in the Prehospital Setting in Rwanda: Results of a Mixed-Methods Quality Improvement Project

Introduction

Pain is a universal human experience tied to an individual's health but difficult to understand. It is especially important in health emergencies. We performed a two-step quality improvement project to assess pain management by the SAMU ambulance service in Kigali, Rwanda, examining how pain is assessed and treated by ambulance staff to facilitate development of standardized guidelines of pain management in the prehospital setting, which did not exist at the time of the study.

Materials and Methods

Deidentified ambulance service records from December 2012 to May 2016 were analyzed descriptively for patient demographics, emergency conditions, pain assessment, and medications given. Then, anonymized, semistructured interviews of ambulance staff were conducted until thematic saturation was achieved. Data were analyzed using a grounded theory approach.

Results

SAMU managed 11,161 patients over the study period, of which 6,168 (55%) were documented as reporting pain and 5,010 (45%) received pain medications. Men had greater odds of receiving pain medications compared to women (OR = 3.8, 95% CI (3.5, 4.1), p < 0.01). Twenty interviews were conducted with SAMU staff. They indicated that patients communicate pain in different ways. They reported using informal ways to measure pain or a standardized granular numeric scale. The SAMU team reviewed these results and developed plans to modify practices.

Conclusions

We reviewed the existing quality of pain management in the prehospital setting in Kigali, Rwanda, assessed the SAMU staff's perceptions of pain, and facilitated standardization of prehospital pain management through context-specific guidelines.

Adaptation of the Multidimensional Pain Evaluation Scale: A Cross-Cultural Study

BACKGROUND AND PURPOSE

Instruments to measure pain must be cross-culturally adapted through rigorous processes, so they can provide equivalence of measure regardless of the context in which they are applied. The study aim was to perform a cross-cultural adaptation of Multidimensional Pain Evaluation Scale (MPES) for use in the United States.

METHODS

Cross-cultural adaptation study entailed translation, back translation, and review by a committee, face and content validity and pilot testing with 90 participants with acute or chronic pain from United States. The Cronbach's alpha coefficient was calculated.

RESULTS

Some items of MPES was changed to maintain the highest level of similarity between the original scales in Portuguese and adapted to English.

CONCLUSION

The Cronbach's alpha was high showed this scale has internal consistency and reliability.

Frequency, nature and management of patient-reported severe acute pain episodes in the over-the-counter setting: results of an online survey

Aim: Understand the frequency, nature and over-the-counter (OTC) self-management of patient-reported severe acute pain occasions. Patients & methods: A consumer-based survey of adults experiencing acute pain in Australia, Russia and the UK. Participants recorded pain type, frequency and intensity plus action taken to address pain. Results: A total of 2994 participants completed the survey; 1366 provided ≥1 diary entry (total 6527 pain occasions). Of these, 744 (11%) were reported as severe, and 72% were treated with OTC medication. Participants were somewhat satisfied/very satisfied with the action taken for 87% of pain occasions overall, and for 83% of severe pain episodes; however, participants with severe pain were somewhat/very dissatisfied with treatment in 9% of cases. Conclusion: Acute pain episodes described as 'severe' are not uncommon in the self-management setting; most can be managed successfully with self-medication. Individuals seeking strong OTC pain relief should be supported to consider self-management strategies first, before considering prescription medication.

Pilot Testing the Clinically Aligned Pain Assessment (CAPA) Measure

BACKGROUND

Pain is one of the most common symptoms experienced by patients in acute care hospitals and acutely ill patients experience both acute and chronic pain. Unrelieved pain can have a profound negative impact on individuals' functional status, well-being, quality of life, and satisfaction with care. For providers, managing pain can be challenging. While the numeric rating scale is widely accepted and used, it measures only pain intensity. CAPA® pain assessment offers an alternative approach in which providers have a conversation with patients about pain and how it impacts five key areas.

AIMS

The purpose of this pilot project was to evaluate provider and patient satisfaction with the CAPA® measure as compared to a numeric rating scale when evaluating patients' experience with pain.

DESIGN

A mixed methods qualitative design was employed.

SETTING

This study was conducted at a 247-bed community teaching hospital in Providence, RI.

PARTICIPANTS

The target sample included patients admitted to the study units and providers who delivered care to patients on the study units and used the numeric rating scale and the CAPA® method of assessment.

METHODS

In focus groups, nurses and physicians were asked about satisfaction with evaluating patients' pain with the numeric rating scale as compared to CAPA®. During a one-to-one interview, patients were asked to describe their impressions of the two assessment measures.

RESULTS

Nurses, physicians, and patients were satisfied that CAPA® effectively evaluated pain and provided more information about pain than the numeric rating scale.

CONCLUSIONS

CAPA® is recommended as a supporting assessment to evaluate patients' pain experience in acute care.

Characteristics of Chronic Pain among Head and Neck Cancer Patients Treated with Radiation Therapy: A Retrospective Study

Pain is common among patients with head and neck cancer (HNC). However, there are very limited data on chronic pain among HNC patients treated with radiation therapy (XRT). In this retrospective study, we focused on the characteristics of chronic post-XRT pain in such patients. Post-XRT pain is common among HNC patients; however, we found discrepancy between frequency of treatment and frequency of chronic pain, suggesting poor documentation of pain in the medical records. Among patients who reported to have chronic post-XRT pain, most of them described having severe pain and used descriptors of neuropathic pain. Pharynx was the commonest site of cancer as well as the commonest site of cancer-related chronic pain; squamous cell carcinoma was the most frequent histological pattern, and opioids were used most often to treat such chronic pain. There was a significant association between chronic pain and number of sites of pain, and chronic pain was also associated with use of opioids.

Pain management in hospitals: patients' satisfaction and related barriers

Background:

Suboptimal pain control has been frequently reported in healthcare settings and documented to negatively impact patients’ health. Patients’ perception regarding pain management may influence their satisfaction regarding treatment.

Objectives:

This study focuses on the assessment of patients’ satisfaction regarding pain therapy and defining patient-related barriers for its implication.

Methods:

A cross-sectional study was conducted in two tertiary care hospitals from April till July 2017. A face-to face interview questionnaire was filled regarding pain scores and patients’ attitudes regarding pain management. Both medical and post-surgical adult patients with all types of pain were eligible to participate. A descriptive analysis of patient satisfaction and perceptions regarding pain management was done.

Results:

Results from 183 participants with a mean age of 49 (SD=17.33) revealed that pain was their main reason for hospitalization (71.6% of the cases). Numeric pain scores were recorded only in 14.2% of the patient medical files. Pain intensity documentation by healthcare professionals was found in 41.5% of the cases, and 7.7% of the patients had to wait for more than 30 minutes before getting the pain medication. Around 85% of the patients were satisfied with their pain management. Patients’ barriers to effective pain therapy were mainly fear of adverse effects, addiction, and additional costs (p<0.05).

Conclusions:

Pain remains a prevalent problem that requires more efforts for improvement. Our study can effectively serve as a start for larger studies where barriers to pain management can be assessed as an independent variable affecting pain management practice.

Efficacy of perineural dexamethasone with ropivacaine in thoracic paravertebral block for postoperative analgesia in elective thoracotomy: a randomized, double-blind, placebo-controlled trial

Purpose

The purpose of this study was to assess the efficacy of perineural dexamethasone with ropivacaine in multimodal analgesia for thoracic paravertebral block (TPVB) in patients undergoing elective thoracotomy.

Patients and methods

Ninety-six patients undergoing thoracotomy were enrolled in this trial and randomized to adjuvant therapy for TPVB: group S (saline), group R (0.5% ropivacaine), or group RD (5 mg dexamethasone and 0.5% ropivacaine). Postoperative analgesia, recovery duration, and chronic pain were recorded.

Results

Groups R and RD spent less time in the postanaesthesia care unit, had earlier out-of-bed activity, and had shorter postoperative hospital stays compared with group S. The RD group regained consciousness faster and had lower acute pain scores and used less patient-controlled analgesia during the first 72 h after surgery compared with group S. Postthoracotomy pain was decreased in group RD (19.0%) compared with group S (47.6%) 3 months postoperatively, p = 0.050.

Conclusion

Perineural dexamethasone with ropivacaine for TPVB improves postoperative analgesia quality, reduces recovery time, and may decrease the incidence of chronic pain after thoracotomy with an opioid-based anesthetic regimen.

Recommendations for Evaluation and Management of Pain in Patients With Mucopolysaccharidosis in Latin America

The mucopolysaccharidosis (MPS) constitutes a heterogeneous group of rare genetic disorders caused by enzymatic deficiencies that lead to the accumulation of glycosaminoglycans. Several types of MPS are described, historically numbered from I to IX. Clinical observations strongly suggest the presence of chronic pain in patients with all types of MPS. There are few data in the literature on the evaluation and management of pain in these patients, a fact that can compromise the quality of life even more. Professionals with extensive experience in the care for patients with MPS held a meeting in April 2017 to discuss and propose recommendations for the evaluation and management of pain in patients with MPS in Latin America. This article summarizes the content of the discussions and presents the recommendations produced at the meeting. Patients with MPS present joint, bone, and muscle pain, as well as entrapment syndromes (spinal, optic nerve, carpal tunnel). The panel suggests the use of the following instruments for pain assessment: Face, Legs, Activity, Cry and Consolability Scale for children of up to four years of age and patients unable to communicate their pain; Child Health Assessment Questionnaire Scale; Facial Pain Scale and Numerical Pain Scale for patients of five to <18 years of age; Brief Pain Inventory and Short Form Health Survey 36 scales for patients aged 18 years or older. Based on the scores verified in these scales, the panel proposes pharmacological interventions for pain relief in this population of patients.

Interdisciplinary assessment-oriented treatment of fibromyalgia: a case report

Patients with fibromyalgia (FM) have often tried many outpatient treatments, and breakthrough pain frequently stops them from performing everyday tasks and participating in society. FM-pain that has become chronic, therefore, affects quality of life. This case study describes the administration of interdisciplinary inpatient pain therapy due to a primary diagnosis of fibromyalgia with integrated complementary medicine. The female patient, who had several concomitant disorders and had been suffering from pain for many years, benefited from the holistic treatment approach in terms of a reduction in pain and an improvement in physical functions and mental health. The ability to have a positive effect on pain symptoms in the longer term is essential. Compliance with the treatments used should also be improved, so that a healthier lifestyle and better pain management can continue after discharge from hospital. These results are supported by other study results and should provide the impetus for major studies to evaluate holistic pain therapies in FM.

Qualities of Sore Throat Index (QuaSTI): measuring descriptors of sore throat in a randomized, placebo-controlled trial

Aim: Patients with pharyngitis often describe various sensory, affective and evaluative pain qualities. Using an 11-word/phrase index, the Qualities of Sore Throat Index (QuaSTI), we characterized throat symptoms and evaluated changes in a randomized controlled trial (NCT01986361). Materials & methods: Patients received a single flurbiprofen 8.75 mg (n = 101) or placebo (n = 21) lozenge and rated throat soreness at baseline and regular intervals over 3 h, and the QuaSTI at baseline, 1, 2 and 3 h post-treatment. Results: The QuaSTI distinguished active drug from placebo and detected clinically important (≥2-point) changes over 3 h. Mean change from baseline over 3 h was significantly greater for flurbiprofen (154%) than placebo (p < 0.05). Conclusion: The QuaSTI is a sensitive instrument for measuring therapeutic effects in patients with pharyngitis.

Role of voltage-gated sodium channel blockers in the treatment of chronic pain: Potential uses in clinical practice based on available evidence

Once patients have failed first line therapy, there is an apparent lack of knowledge on how to proceed with choosing subsequent therapy. To choose amongst alternative agents, an understanding of pharmacology, pharmacokinetics, and available evidence in targeting various pain conditions is necessary. This article focuses on the use of the carboxamide class of voltage-gated sodium channel blockers (carbamazepine, oxcarbazepine, eslicarbazepine acetate) for adjunct pain medication management; including research updates in pharmacology, pharmacokinetics, and evidence for pain along on this therapeutic group with promising future areas of research. Although evidence for voltage-gated sodium channel blockers in chronic pain management is limited, emerging research has identified this area as promising for additional clinical trials to better guide clinical practice.

Effectiveness of the Concurrent Intravenous Injection of Dexamethasone and Metoclopramide for Pain Management in Patients with Primary Headaches Presenting to Emergency Department

Introduction:

Headache is a common reason for visiting emergency departments, and pain control is a major therapeutic goal in patients with headaches.

Objective:

The present study was conducted to examine the effectiveness of the concurrent intravenous administration of dexamethasone and metoclopramide in pain control in patients presenting to emergency departments with complaints of primary headache.

Methods:

This quasi-experimental study examined patients with moderate to severe headache attacks presenting to emergency departments. An 8-mg dose of dexamethasone and a 10-mg dose of metoclopramide were intravenously administered to the patients. The degree of headache was measured and recorded using the Numeric Rating Scale (NRS) upon admission and one hour and two hours after the injection.

Results:

A total of 51 patients with a mean age of 38.3±10.5 years participated in the study. The patients’ mean pain score was 8.4±1.3 upon admission and reduced to 6.2±2.3 one hour after the administration of the medication and to 3.1±2.9 two hours after the administration, suggesting significant reductions on both occasions (P<0.05). The therapeutic success was 39.2% one hour after the administration of the medication and 84.3% two hours after the administration.

Conclusion:

Based on these findings, the concurrent administration of dexamethasone and metoclopramide appears to affect the control of headache intensity in patients with primary headaches presenting to emergency departments.

Old Friends With New Faces: Are Sodium Channel Blockers the Future of Adjunct Pain Medication Management?

Providers are being asked to decrease the emphasis and overutilization of long-term opioid therapy, but many are left without proper guidance on appropriate utilization of nonopioid therapies. Furthermore, therapeutic options are quite limited and many providers lack confidence in distinguishing available alternatives. When first-line therapy has failed in a patient, there is an apparent lack of knowledge on how to proceed with choosing subsequent therapy. To choose among alternative agents, an understanding of pharmacology, pharmacokinetics, and efficacy in targeting various pain conditions is necessary. This article focuses on the use of the carboxamide class of sodium channel blockers (carbamazepine, oxcarbazepine, eslicarbazepine) for adjunct pain medication management including research updates in pharmacology, pharmacokinetics, and current evidence for pain along with promising areas of research. It is an evidence update for clinical use of sodium channel blockers, clarifies misconceptions regarding their use, and highlights emerging research for improved pain targets that justifies additional study. We performed a complete review of the literature using the search terms, "oxcarbazepine," "carbamazepine," and "eslicarbazepine" in conjunction with "pharmacokinetics," "adverse effects," "pharmacology," "voltage-gated sodium channel subtype," "neuropathic pain," "inflammatory pain," "metabolism," "epoxide metabolite formation," "drug interactions," "CYP450 interactions," "pain phenotype," and "chronic pain management." Databases searched included PubMed and Google Scholar. Package inserts were used for drug structure illustration, adverse reactions, and bioavailability. Pharmacology and pharmacokinetic data were taken from randomized controlled trials evaluating this area as well as in vitro published results. For validity, only peer-reviewed literature was included. Evidence for sodium channel blockers in chronic pain management was limited. This review focuses on highlighting the data available for the use of sodium channel blockers for certain pain syndromes as well as underutilized potential. Emerging literature on sodium channel subtypes and their connection to neuropathic, inflammatory, and mechanical pain transmission is elucidated. The authors also scrutinize literature surrounding the pharmacokinetics of oxcarbazepine and eslicarbazepine to provide clearer guidance to the significance of any drug interactions and refute assumptions made on the basis of structural similarity to carbamazepine and its known undesirable drug interactions. Side effect profiles are outlined and compared, emphasizing the differences between agents. Sodium channel blocker doses used in certain pain syndromes are outlined with a call for further research to better understand their place in chronic pain management. Identification of sodium channel subtypes with links to specific pain conditions and the ability to target them hints at the potential for truly individualized therapy. Sodium channel inhibitors are underutilized on the basis of available evidence, and emerging research has identified this area as promising for additional clinical trials to better guide clinical practice.

PERSPECTIVE

This article provides a review of the pharmacology, evidence for pain management, and pharmacokinetics of oxcarbazepine, carbamazepine, and eslicarbazepine. There is a disparity in evidence using sodium channel blockers for pain and this article highlights the potential that is currently underutilized. The authors believe this will catalyze interest for further studies.

Cancer pain management in China: current status and practice implications based on the ACHEON survey

Purpose

Cancer pain can seriously impact the quality of life (QoL) of patients, and optimal management practices are therefore of paramount importance. The ACHEON survey queried physicians and patients from 10 Asian countries/regions to assess current clinical practices in cancer pain management in Asia. This study presents the data obtained for cancer pain management in mainland China, with an emphasis on practices related to opioid drugs.

Materials and methods

In several tertiary hospitals across China, 250 patients experiencing cancer pain and 100 physicians were surveyed on questions designed to assess current cancer pain management practices and cancer pain impact on QoL.

Results

The patient survey showed that 88% of patients reported moderate-to-severe cancer pain, with a median duration of 6 months. The physician survey showed that medical school/residency training with regard to cancer pain management was inadequate in ~80% of physicians. A total of 80% of physicians and 67.2% of patients reported that pain scale was used during pain assessment; 84% of physicians expressed that physician-perceived pain severity was not completely consistent with actual pain the patient experienced. Of the 147 patients who recalled the medication received, 83.7% were administered opioid prescriptions. Of the 240 patients who received treatment, 43.8% perceived the inadequacy of controlling pain. The primary barriers from physicians perceived to optimal pain management included patients’ fear of side effects (58%), patients’ fear of addiction (53%), patients’ reluctance to report pain (43%), physicians’ reluctance to prescribe (29%), physicians’ inadequacy of pain assessment (27%) and excessive regulation of opioid analgesics (47%).

Conclusion

Knowledge of cancer pain management should be strengthened among physicians. Quantitative pain assessment and principle-based pain management should be combined to achieve pain relief. Misconceptions about opioids in patients and physicians and poor report about pain should be overcome through training/education to improve QoL of patients impacted by pain.

Pain reporting and analgesia management in 270 children with a progressive neurologic, metabolic or chromosomally based condition with impairment of the central nervous system: cross-sectional, baseline results from an observational, longitudinal study

Little is known about the prevalence, characterization and treatment of pain in children with progressive neurologic, metabolic or chromosomal conditions with impairment of the central nervous system. The primary aims of this study were to explore the differences between parental and clinical pain reporting in children with life-limiting conditions at the time of enrollment into an observational, longitudinal study and to determine if differences in pain experiences were associated with patient- or treatment-related factors. Pain was common, under-recognized and undertreated among the 270 children who enrolled into the "Charting the Territory" study. Children identified by their parents as experiencing pain (n=149, 55%) were older, had more comorbidities such as dyspnea/feeding difficulties, were less mobile with lower functional skills and used analgesic medications more often, compared to pain-free children. Forty-one percent of children with parent-reported pain (21.8% of all patients) experienced pain most of the time. The majority of clinicians (60%) did not document pain assessment or analgesic treatment in the medical records of patients who were experiencing pain. Documentation of pain in the medical record was positively correlated with children receiving palliative care services and being prescribed analgesics, such as acetaminophen, nonsteroidal anti-inflammatory drugs and opioids, as well as the adjuvant analgesics gabapentin and amitriptyline.

“Pain Is What the Patient Says It Is”: Nurse–Patient Communication, Information Seeking, and Pain Management

Nurse–patient conversations about pain management are complex. Given recent increases in prescription pain pill abuse, such interactions merit scholarly attention. In-depth interviews with 21 nurses were conducted to explicitly explore nurses’ information seeking about pain. The participants in this study gathered pain information from patients through a variety of means and reported facing challenges and dilemmas when communicating with patients about pain management and medicinal preferences. These results have important implications for nurses, patient outcomes, and the broader health-care system and imply that continued educational and intervention efforts are essential in this complicated communicative context.

Physicians' Attitudes to Clinical Pain Management and Education: Survey from a Middle Eastern Country

Despite promising initiatives to advance the practice of pain management in Middle Eastern countries, their pain care lags behind developed countries. The objectives of this study are to evaluate physicians' assessment of their own competency in pain management, to assess physicians' practice related to pain management, and to identify physician-related barriers to effective pain control. A cross-sectional survey was conducted in 3 teaching medical centers in Lebanon targeting the above-mentioned outcomes and assessing the impact of physicians' years in practice on the studied end-points. A total of 69 physicians were surveyed. Fifty-seven percent reported "very good to excellent" pain management skills; only 25% of them described the need for continuing professional development. When treating patients with pain, 52% of physicians refer to updated international guidelines, whereas 43% rely on their own judgment. Physicians were more likely to consult with another physician (65%) rather than a pharmacist (12%) when treating patients with pain. Fear of adverse effects of analgesics was the most commonly reported barrier (45%) to pain control among physicians from different career stages. Based on these survey findings, national pain management and practice policies are needed to optimize this area of deficiency in patient care.

Relationship Between Botulinum Toxin, Spasticity, and Pain: a Survey of Patient Perception

Objective: To assess the prevalence of pain in adults with spasticity and to assess the association between the subjective experience of pain and spasticity. Design: Cross-sectional study. Setting: outpatient spasticity management clinic of a rehabilitation centre. Patients: Patients with upper motor neuron lesions and spasticity (n=131) were recruited. Methods: We assessed pain intensity and location, relationship between spasticity and pain perception, and perception of pain relief from botulinum toxin type-A (BoNTA) injections. Main outcome measures: Pain perception rated on a 10-point numerical rating scale and pain quality. Results: 65% of the patients with spasticity reported presence of pain and 60% described it as an aching pain. More patients reported pain with movement (34%) compared to rest (21%). There was a statistically poor correlation between the severity of pain and spasticity (r=0.16; p>0.05). Most patients (80%) believed that their pain was related to spasticity and 62% reported that BoNTA injections decreased their pain. Conclusions: The high incidence of pain noted within our sample suggests that physicians may have to consider pain management as part of spasticity treatment. Participants reported that their pain was related to their spasticity, and that it decreased after BoNTA treatment. Further study is needed to explore the relationships between objective measures of spasticity and pain.
