Comparison of the psychometric properties of 3 pain scales used in the pediatric emergency department: Visual Analogue Scale, Faces Pain Scale-Revised, and Colour Analogue Scale

An exploration of clinical features and factors associated with pain frequency and pain intensity in children with growing pains: a cross-sectional study from Chongqing, China

Instruction

Growing pains are the most common cause of musculoskeletal pain in children, affecting both children's and caregivers' well-being. The lack of definitive diagnostic criteria complicates diagnosis and treatment.

Objectives

This study aims to outline the clinical features and identify factors associated with the frequency and intensity of growing pains in children in Chongqing, China.

Methods

A cross-sectional study was conducted in a children's hospital using its Internet hospital follow-up platform. Children initially diagnosed with growing pains between July and September 2022 were enrolled. Sociodemographics, pain locations, duration, frequency, intensity, and potentially related factors were collected.

Results

Eight hundred sixty-three children were enrolled (average age: 8.19 ± 3.24 years; 455 boys [52.72%]). Pain frequency was reported as quarterly (62.11%), monthly (24.80%), biweekly (1.74%), weekly (10.08%), and daily (1.27%). The prevalence of mild, moderate, and severe pain was 26.65%, 55.74%, and 17.61%, respectively. The knee was the most common pain location (63.85%), mostly encountered between 4 pm and 5 pm (20.51%). Multivariate analysis revealed that pain frequency negatively correlated with vitamin supplementation during pregnancy, positively correlated with underweight, bad temper, increased exercise, and cold lower extremities. Pain intensity positively correlated with irritability, increased exercise, and pain sensitivity but negatively correlated with age and vitamin supplementation during lactation.

Conclusion

Growing pains typically occur on a quarterly basis, predominantly affecting the knees during 4 pm to 5 pm. Factors in sociodemographics, maternal aspect, temperament, and exercise levels can influence pain frequency and intensity. Clinicians should consider these aspects when developing comprehensive strategies for pain management.

A systematic review of temporomandibular disorder diagnostic methods

Objective: To compile the screening tools used to study temporomandibular disorders (TMD), classify and analyze their potential application in the field of physiotherapy.Methods: All gathered data included randomized clinical trials on humans over 18 years of age pulled from three databases up to November 2019.Results: Nineteen articles were retained, in which the subjects included 1095 women and 385 men. The 32 valuation systems reported were classified as follows: direct, requiring observation and/or palpation in situ by a clinician, which can be subdivided into protocols and instrumental systems; and indirect, requiring neither observation nor palpation by a clinician, which can be subdivided into questionnaires and scales.Conclusion: In order to evaluate TMD, the best choice is to combine direct and indirect assessment methodologies. The valuation of pressure pain threshold with an algometer and Fonseca's Anamnestic Index in combination with Anamnestic Questionnaire CMD, respectively, seems to provide the best results.

The efficacy of articaine in pain management during endodontic procedures in pediatric patients

OBJECTIVE

This trial aimed to study the efficacy of articaine in pain management during endodontic procedures in pediatric patients.

METHODS

Ninety-eight children who received endodontic painless treatment were collected and randomly divided into the control group and observation group, with 49 cases in each group. The control group received infiltration anesthesia with lidocaine, and the observation group received infiltration anesthesia with articaine. Anesthesia effect, anesthesia onset time, sensory recovery time, duration of anesthesia, pain intensity, blood pressure, heart rate, and adverse reactions were compared.

RESULTS

The effective rate of anesthesia in the observation group was higher than that in the control group. The anesthesia onset time and sensory recovery time were shorter, the duration of anesthesia was longer, and the VAS score and facial expression score were lower in the observation group than in the control group. The heart rate of the observation group was lower, and diastolic blood pressure was higher than those of the control group. The total incidence of adverse reactions in the observation group was lower than that in the control group.

CONCLUSION

In the treatment of dental pulp diseases in children, the use of articaine can achieve better anesthesia effect and rapid onset of anesthesia and has less impact on the patient's blood pressure and heart rate, but it also can relieve pain and has good safety after the use of medication. It is worthy of clinical application.

The level of agreement between the numerical rating scale and visual analogue scale for assessing pain intensity in adults with chronic pain

The numerical rating scale and visual analogue scale are used to quantify pain intensity. However, it has not yet been explored whether these scores are interchangeable in adults with chronic pain. Data from the prospective multicentre cross-sectional INTERVAL study were used to evaluate the one-dimensionality and agreement between numerical rating scale scores and visual analogue scale scores in adults with chronic pain. Pain intensity scores using the numerical rating scale and visual analogue scale were provided by 366 patients with chronic pain for current, average, minimal and maximal pain. To evaluate whether pain intensity scales are completed in accordance with each other, the proportion of patients who satisfied the following condition was calculated: minimal pain intensity ≤ maximal pain intensity. A factor analysis confirmed the one-dimensionality of the pain measures. A significant difference was found between numerical rating scale and visual analogue scale scores for average, current, minimum and maximum pain. Intra-class correlation coefficient estimates ranged from 0.739 to 0.858 and all measures failed to show sufficient and acceptable agreement at the 95% level. The strength of agreement between pain severity categories was classified as 'moderate' for average and minimal pain and 'substantial' for current and maximal pain. The proportion of patients who scored minimal pain ≤ maximal pain was 97.5% for the numerical rating scale and 89.5% for the visual analogue scale. This study failed to show an acceptable agreement between the numerical rating scale and visual analogue scale when pain intensity was rated by adults with chronic pain, despite showing both scales measure the same information.

A multi-dimensional assessment of internet gaming disorder in children and adolescents: A case-control study

BACKGROUND

Internet gaming disorder (IGD) leads to social disturbances and isolation, neglect of daily responsibilities, behavioral disorders, and physical impairments.

OBJECTIVE

This study aimed to investigate the effect of IGD on spine biomechanics, range of motion in the neck and low back, and lung functions and respiratory muscle strength in children and adolescents.

METHODS

Sixty-four children and adolescents with IGD (Group I) and 41 healthy controls (Group II) were included in the study. The outcomes were assessed with the Visual Analogue Scale (VAS), Internet Addiction Scale, active range of motion (AROM) in the neck and lumbar spine, posture and spinal alignment, lung function tests, and respiratory muscle strength.

RESULTS

There is a significant difference in pain intensity at rest, during activity, and daily sitting time between groups (p < 0.05). Craniovertebral angle, shoulder asymmetry, thoracic kyphosis angle, cervical extension and rotation, and right lumbar rotation significantly decreased in Group I than in Group II (p < 0.05). Besides, the PEF, FEF 25-75%, and respiratory muscle strength were lower in Group I than in Group II (p < 0.05). With a multiple linear regression model, MEP, FEV1, and weekly time spent playing online games were significant predictors of internet addiction intensity (R2 = 0.28; p = 0.02, p = 0.01, and p < 0.001, respectively).

CONCLUSION

Postural misalignment and increased sedentary time cause physical health deterioration and negatively affect lung functions in children and adolescents with IGD. Consequently, considering both psychological and physical health is necessary to assess the problematic nature of internet gaming. A comprehensive assessment and multidisciplinary team approach is essential to managing the IGD.

Effects of Using Guided Deep Breathing Exercises in a Virtual Natural Environment to Reduce Stress during Pediatric Treatment

There exists a need for new methods to address treatment anxiety in pediatrics-at the same time, deep breathing exercises and virtual natural environments have both been known to have stress-reducing qualities. This article reports the combined effect of these two methods in a pediatric setting. A feasibility study was conducted in a local hospital. The study had a within-subjects design, and it included 21 child patients aged 8 to 12 years old, who used a virtual reality (VR) relaxation application developed for this purpose during an intravenous cannulation procedure related to their treatment. The key findings highlight a statistically very significant stress reduction associated with the utilized VR intervention, demonstrated by heart rate variability measurements (SDNN, p < 0.001; RMSSD, p = 0.002; Stress Index, p < 0.001; LF/HF ratio, p = 0.010). This effect was consistent regardless of the level of general anxiety or the level of needle phobia of the patient, and no adverse effects were observed. The results show the strong potential of using deep breathing exercises in virtual natural environments for addressing treatment anxiety related to invasive pediatric procedures.

Psychometric evaluation of the electronic faces thermometer scale for pain assessment in children 8-17 years old: A study protocol

It is often a challenge for a child to communicate their pain, and their possibilities to do so should be strengthened in healthcare settings. Digital self-assessment provides a potential solution for person-centered care in pain management and promotes child participation when a child is ill. A child's perception of pain assessment differs when it is assessed using digital or analog formats. As we move into the digital era, there is an urgent need to validate digital pain assessment tools, including the newly developed electronic Faces Thermometer Scale (eFTS). This study protocol describes three studies with the overall aim to evaluate psychometric properties of the eFTS for assessing pain in children 8-17 years of age. A multi-site project design combining quantitative and qualitative methods will be used for three observational studies. Study 1: 100 Swedish-speaking children will report the level of anticipated pain from vignettes describing painful situations in four levels of pain and a think-aloud method will be used for data collection. Data will be analyzed with phenomenography as well as descriptive and comparative statistics. Study 2: 600 children aged 8-17 years at pediatric and dental settings in Sweden, Denmark, Iceland, and USA will be included. Children will assess their pain intensity due to medical or dental procedures, surgery, or acute pain using three different pain Scales for each time point; the eFTS, the Faces Pain Scale Revised, and the Coloured Analogue Scale. Descriptive and comparative statistics will be used, with subanalysis taking cultural context into consideration. Study 3: A subgroup of 20 children out of these 600 children will be purposely included in an interview to describe experiences of grading their own pain using the eFTS. Qualitative data will be analyzed with content analysis. Our pilot studies showed high level of adherence to the study procedure and rendered only a small revision of background questionnaires. Preliminary analysis indicated that the instruments are adequate to be used by children and that the analysis plan is feasible. A digital pain assessment tool contributes to an increase in pain assessment in pediatric care. The Medical Research Council framework for complex interventions in healthcare supports a thorough development of a new scale. By evaluating psychometric properties in several settings by both qualitative and quantitative methods, the eFTS will become a well-validated tool to strengthen the child's voice within healthcare.

Electronic Health Record Recording of Patient Pain: Challenges and Discrepancies

PURPOSE OF REVIEW

In the present review, various categories of pain, clinician-observed pain scales, and patient-reported pain scales are evaluated to better understand factors that impact patient pain perceptions. Additionally, the expansion of areas that require further research to determine the optimal way to evaluate pain scale data for treatment and management are discussed.

RECENT FINDINGS

Electronic health record (EHR) data provides a starting point for evaluating whether patient predictors influence postoperative pain. There are several ways to assess pain and choosing the most effective form of pain treatment. Identifying individuals at high risk for severe postoperative pain enables more effective pain treatment. However, there are discrepancies in patient pain reporting dependent on instruments used to measure pain and their storage in the EHR. Additionally, whether administered by a physician or another healthcare practitioner, differences in patient pain perception occur. While each scale has distinct advantages and limitations, pain scale data is a valuable therapeutic tool for assisting clinicians in providing patients with optimal pain control. Accurate assessment of patient pain perceptions by data extraction from electronic health records provides a potential for pain alleviation improvement. Predicting high-risk postoperative pain syndromes is a difficult clinical challenge. Numerous studies have been conducted on factors that impact pain prediction. Postoperative pain is significantly predicted by the kind of operation, the existence of prior discomfort, patient anxiety, and age.

The Effectiveness of the Buzzy Device in Reducing Pain in Children Undergoing Venipuncture: A Single-Center Experience

OBJECTIVES

Needle-related procedures are among the most important sources of pain in children in different health care settings. Our study was aimed to evaluate the effectiveness of Buzzy (MMJ Labs, Atlanta, Ga.), a palm-sized bee/ladybug-shaped device combining vibration and cold, as a nonpharmacological strategy to manage needle-related pain in children.

METHODS

In this single-center, randomized (1:1) controlled open-label study, we enrolled patients aged from 1 month to 18 years who had to undergo a planned outpatient blood sampling in Pisa University Hospital's Department of Pediatrics and randomly allocated them to either the BUZZY group (intervention group) or NO BUZZY group (control group). Pain was estimated using proper pain scales according to age.

RESULTS

Between May 2021 and January 2022, 234 children aged 8.8 ± 5.1 years (50.8% girls) were enrolled and 117 were treated with the Buzzy device. In the study population, pain inversely correlated with age (r = -0.52, P < 0.001); the intervention group showed significantly lower pain (2.5 ± 2.4 vs 4.7 ± 2.8, P < 0.001) and no difference was found between boys and girls. Significant reduction in pain scores was confirmed when stratifying children by age (29 days to <3 years, P = 0.002; ≥3 to ≤8 years, P < 0.001; >8 years, P < 0.001).

CONCLUSIONS

The Buzzy device effectively reduces pain caused by percutaneous antecubital venipuncture in children in different age groups and represents a cheap and easy-to-use strategy to manage routine needle-related procedures.

Assessing independence in mobility activities in trauma care: Validity and reliability of the Activity Independence Measure-Trauma (AIM-T) in humanitarian settings

The importance of measuring outcomes after injury beyond mortality and morbidity is increasingly recognized, though underreported in humanitarian settings. To address shortcomings of existing outcome measures in humanitarian settings, the Activity Independence Measure-Trauma (AIM-T) was developed, and is structured in three subscales (i.e., core, lower limb, and upper limb). This study aimed to assess the AIM-T construct validity (structural validity and hypothesis testing) and reliability (internal consistency, inter-rater reliability and measurement error) in four humanitarian settings (Burundi, Iraq, Cameroon and Central African Republic). Patients with acute injury (n = 195) were assessed using the AIM-T, the Barthel Index (BI), and two pain scores. Structural validity was assessed through confirmatory factor analysis. Hypotheses were tested regarding correlations with BI and pain scores using Pearson correlation coefficient (PCC) and differences in AIM-T scores between patients' subgroups, using standardized effect size Cohen's d (d). Internal consistency was assessed with Cronbach's alpha (α). AIM-T was reassessed by a second rater in 77 participants to test inter-rater reliability using intraclass correlation coefficient (ICC). The results showed that the AIM-T structure in three subscales had an acceptable fit. The AIM-T showed an inverse weak to moderate correlation with both pain scores (PCC<0.7, p≤0.05), positive strong correlation with BI (PCC≥0.7, p≤0.05), and differed between all subgroups (d≥0.5, p≤0.05). The inter-rater reliability in the (sub)scales was good to excellent (ICC 0.86-0.91) and the three subscales' internal consistency was adequate (α≥0.7). In conclusion, this study supports the AIM-T validity in measuring independence in mobility activities and its reliability in humanitarian settings, as well as it informs on its interpretability. Thus, the AIM-T could be a valuable measure to assess outcomes after injury in humanitarian settings.

Effectiveness of physical stimulation for reducing injection pain in adults receiving intramuscular injections: a systematic review and meta-analysis

OBJECTIVE

The objective of this review was to synthesize the best available research evidence regarding the effectiveness of physical stimulation for reducing injection pain in adults receiving intramuscular injections.

INTRODUCTION

Pain associated with intramuscular injections continues to be a challenge for nurses. Various physical stimulation methods to alleviate pain and improve satisfaction for patients receiving intramuscular injections have been reported; however, the evidence surrounding the effectiveness of these methods remains inconclusive.

INCLUSION CRITERIA

This systematic review considered randomized and quasi-experimental studies that used any physical stimulation strategies (eg, skin tapping, manual pressure, massage, pinch, traction) for adults aged 18 years and over receiving intramuscular injections. Studies that evaluated pain using validated instruments were considered for inclusion.

METHODS

A three-step search strategy was conducted. MEDLINE, Embase, CINAHL, the Cochrane Library (Cochrane CENTRAL), Google Scholar, Dissertation Abstracts International, ProQuest Dissertations and Theses, and MedNar were searched from inception until 2020. We restricted the inclusion of studies to trials published in English. Two independent reviewers conducted the critical appraisal of eligible studies using the JBI checklists for randomized controlled and quasi-experimental trials. Data were extracted using the JBI data extraction tool, and meta-analysis and subgroup analysis were undertaken, where appropriate.

RESULTS

Twenty-five studies were included with a total sample size of 1956 patients. Pooled results demonstrated that pain was significantly less with the use of the Helfer skin tap technique compared to no intervention (two studies; RR 0.73; 95% CI 0.66, 0.81; P <0.00001) or standard intervention (three studies; SMD -2.25; 95% CI -3.65, -0.85; P =0.002). Intervention with acupressure using standard treatment as control showed significant reduction in pain intensity (MD -4.78; 95% CI -5.32, -4.24; P <0.00001). Similarly, pain was significantly lower with manual pressure (two studies; SMD -0.42; 95% CI -0.69, 0.15; P =0.002) when compared to standard treatment. Pain scores were significantly lower in patients who received pinch technique, ShotBlocker, massage, or combination intervention (skin traction, pressure, and rapid muscle release) compared with no intervention, standard treatment, or placebo control.

CONCLUSIONS

The evidence from this review demonstrates that physical stimulation - particularly the Helfer skin tap technique, acupressure, manual pressure, pinch technique, ShotBlocker, massage, and combination - can significantly lower intramuscular injection pain; however, this is based on low or very low certainty of evidence.

Diagnostic criteria for temporomandibular disorders-INfORM recommendations: Comprehensive and short-form adaptations for children

BACKGROUND

The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) are used worldwide in adults. Until now, no adaptation for use in children has been proposed.

OBJECTIVE

The aim of this study was to present comprehensive and short-form adaptations of Axis I and Axis II of the DC/TMD for adults that are appropriate for use with children in clinical and research settings.

METHODS

Global Delphi studies with experts in TMDs and in pain psychology identified ways of adapting the DC/TMD for children.

RESULTS

The proposed adaptation is suitable for children aged 6-9 years. Proposed changes in Axis I include (i) adapting the language of the Demographics and the Symptom Questionnaires to be developmentally appropriate for children, (ii) adding a general health questionnaire for children and one for their parents, (iii) replacing the TMD Pain Screener with the 3Q/TMD questionnaire and (iv) modifying the clinical examination protocol. Proposed changes in Axis II include (i) for the Graded Chronic Pain Scale, to be developmentally appropriate for children, (ii) adding anxiety and depression assessments that have been validated in children and (iii) adding three constructs (stress, catastrophising and sleep disorders) to assess psychosocial functioning in children.

CONCLUSION

The recommended DC/TMD, including Axis I and Axis II, for children aged 6-9 years, is appropriate for use in clinical and research settings. This adapted the first version for children includes changes in Axis I and Axis II changes requiring reliability and validity testing in international settings. Official translations to different languages according to INfORM requirements will enable a worldwide dissemination and implementation.

XyloFUNS: Xylocaine to freeze during unpleasant nasopharyngeal swabs in children-a randomized controlled trial

Objectives

To evaluate the efficacy of intranasal vaporized lidocaine in reducing pain for children undergoing a nasopharyngeal (NP) swab in the Emergency Department (ED).

Study Design

A randomized blinded clinical trial was conducted in a paediatric ED. Both participants and the researcher evaluating the primary outcome were blinded. Children aged 6 to 17 years old requiring a NP swab were eligible. Participants were randomly allocated to receive intranasal lidocaine or a sham treatment prior to their NP swab. The primary outcome measure was pain during the swab as assessed by the visual analog scale. Secondary outcome measures were pain using the verbal numeric rating scale, fear using the children fear scale, and adverse effects of the intervention.

Results

Eighty-eight participants were enrolled-45 in the lidocaine group and 43 controls. The mean visual analog scale scores for pain were 46 mm in the lidocaine group and 53 mm in the control group (mean difference 7 mm; 95% CI: -5 to 19 mm). No serious adverse events were observed.

Conclusions

Intranasal lidocaine administered prior to NP swabs in the ED failed to show an improvement in pain scores for school-aged children and youth.

Dissociation between individual differences in self-reported pain intensity and underlying fMRI brain activation

Pain is an individual experience. Previous studies have highlighted changes in brain activation and morphology associated with within- and interindividual pain perception. In this study we sought to characterize brain mechanisms associated with between-individual differences in pain in a sample of healthy adolescent and adult participants (N = 101). Here we show that pain ratings varied widely across individuals and that individuals reported changes in pain evoked by small differences in stimulus intensity in a manner congruent with their pain sensitivity, further supporting the utility of subjective reporting as a measure of the true individual experience. Furthermore, brain activation related to interindividual differences in pain was not detected, despite clear sensitivity of the Blood Oxygenation Level-Dependent (BOLD) signal to small differences in noxious stimulus intensities within individuals. These findings suggest fMRI may not be a useful objective measure to infer reported pain intensity.

Translation, adaptation and psychometric properties of the Arabic version of the numerical rating scale when used with children and adolescents

OBJECTIVE

The 0-10 Numerical Rating Scale (NRS-11) is widely used with Arabic-speaking pediatric populations. However, there is no data about its validity or reliability. Thus, the aims of this research were to translate the NRS-11 into Arabic and study its dimensionality and construct (convergent and discriminant) validity, and reliability.

METHODS

A group of 190 Lebanese students between 8 and 18 years old participated. Participants were interviewed online and asked to imagine themselves in a hypothetical painful situation and rate the expected pain intensity using the NRS-11-Arabic and an Arabic version of the Visual Analogue Scale (VAS-Arabic). They were also requested to respond to the pediatric Arabic version of the Pain Catastrophizing Scale (PCS-Arabic). Data collection lasted for a month.

RESULTS

Data showed that the NRS-11-Arabic and the VAS-Arabic scores measure the same common construct. In addition, they showed strong statistically significant correlations between NRS-11 and VAS (ranging from 0.83 for the whole sample and 0.83 and 0.84 for the 8-12-year-olds and the 13-18-year-olds, which support its construct validity). These correlations were higher than those between the NRS-11-Arabic and the PCS-Arabic, which support the discriminant validity of NRS-11-Arabic scores. Test-retest reliability was 0.86 for the whole sample, and 0.89 and 0.82 for the 8-12-year-olds and the 13-18-year-olds, respectively, which shows the reliability of the NRS-11-Arabic scores.

CONCLUSIONS

The data provide preliminary evidence of the unidimensionality, validity and reliability of the NRS-11-Arabic scores, thus supporting its use in clinical and research activities involving Arabic-speaking pediatric samples.

Triple Versus Single Application of Lidocaine, Epinephrine, and Tetracaine for Laceration Repair in Children

OBJECTIVE

Lidocaine (4%), epinephrine (0.1%), and tetracaine (0.5%) topical gel (LET) is a safe and effective method of providing anesthesia for laceration repair. Some patients, however, require additional infiltrated local anesthetic. We sought to determine if 3 applications of LET 10 minutes apart (triple LET) result in lower pain scores with suturing than one application for 30 minutes (single LET).

METHODS

We performed a randomized single-blind controlled trial of pediatric emergency department patients 7 to 17 years old with simple lacerations requiring sutures. Patients received either triple or single LET, and the first suture was placed or attempted within 15 minutes of removing the LET. Visual analog pain score on a 100-mm scale was obtained by a blinded nurse. Pain scores between groups were compared using the Wilcoxon rank sum test.

RESULTS

Forty-eight patients were enrolled: 21 for single LET and 27 for triple LET. Mean visual analog pain scale (VAS) score for single LET patients was 16 (SD, 17; range, 0-48), and that for triple LET patients was 16 (SD, 24; range, 0-95), with the difference not significant at 0.37 (95% confidence interval, -11.9 to 12.6). There was no significant difference in requirement for additional anesthesia between single LET (4 of 21 [19%]) and triple LET (5 of 27 [19%]) patients.

CONCLUSIONS

Lidocaine (4%), epinephrine (0.1%), and tetracaine (0.5%) topical gel every 10 minutes for 3 applications was not superior in anesthetic efficacy to applying it once for 30 minutes.

The Arabic Version of the Faces Pain Scale-Revised: Cultural Adaptation, Validity, and Reliability Properties When Used with Children and Adolescents

The Faces Pain Scale-Revised (FPS-R) is widely used to assess pain intensity in young people. The aims of this research were to study the convergent and discriminant validity and reliability properties of a culturally adapted version of the FPS-R for its use with Arabic-speaking individuals. The sample consisted of 292 students living in Lebanon. They were interviewed online, asked to imagine themselves in one of two given situations based on their age (8-12 and 13-18 years old), and then asked rate the intensity of pain they would experience using the FPS-R-Arabic and a Numerical Rating Scale (NRS-11-Arabic). They were also asked to respond to the Pain Catastrophizing Scale (PCS-C-Arabic). Two weeks later, participants were asked to repeat the same procedure. The data showed strong associations between the scores of the FPS-R-Arabic and NRS-11-Arabic (r = 0.72; p < 0.001), which were higher than the associations of the scores of the FPS-Arabic with the PCS-C-Arabic scores (z = 7.36, p < 0.001). The associations between the FPS-R-Arabic scores on the two measurements were also strong (r = 0.76; p < 0.001). The findings support the convergent and discriminant validity and reliability of the FPS-R-Arabic scores when used to measure pain intensity in young people aged 8 to 18 years old.

Pediatric Pain Assessment in the Emergency Department: Patient and Caregiver Agreement Using the Wong-Baker FACES and the Faces Pain Scale-Revised

OBJECTIVE

This study aimed to assess the agreement between patients presenting to the pediatric emergency department (ED) with acute pain and their caregivers when using the Wong-Baker FACES (WBF) and Faces Pain Scale-Revised (FPS-R).

METHODS

This was a prospective, observational study examining patients 3 to 7.5 years old presenting to a pediatric ED with acute pain. Participants completed the WBF and FPS-R twice during their ED evaluation. Caregivers rated their child's pain using both the WBF and FPS-R at the same time points. Intraclass correlations (ICCs) were calculated between caregiver and child reports at each time point, and Bland-Altman plots were created.

RESULTS

Forty-six subjects were enrolled over 5 months. Mean age was 5.5 ± 1.2 years. Average initial child pain scores were 6.6 ± 2.8 (WBF) and 6.1 ± 3.3 (FPS-R), and repeat scores were 3.3 ± 3.4 (WBF) and 3.1 ± 3.3 (FPS-R). Average initial caregiver pain scores were 6.3 ± 2.4 (WBF) and 6.2 ± 2.3 (FPS-R), and repeat scores were 3.4 ± 2.0 (WBF) and 3.4 ± 2.1 (FPS-R). On initial assessment, ICCs between children and caregivers using the FPS-R and WBF were 0.33 and 0.22, respectively. On repeat assessment, the ICCs were 0.31 for FPS-R and 0.26 for WBF. Bland-Altman plots showed poor agreement but no systematic bias.

CONCLUSION

There was poor agreement between caregivers and children when using the WBF and FPS-R for assessment of acute pain in the ED. Caregiver report should not be used as a substitute for self-report of pain if possible.

Prediction Model of Osteonecrosis of the Femoral Head After Femoral Neck Fracture: Machine Learning-Based Development and Validation Study

BACKGROUND

The absolute number of femoral neck fractures (FNFs) is increasing; however, the prediction of traumatic femoral head necrosis remains difficult. Machine learning algorithms have the potential to be superior to traditional prediction methods for the prediction of traumatic femoral head necrosis.

OBJECTIVE

The aim of this study is to use machine learning to construct a model for the analysis of risk factors and prediction of osteonecrosis of the femoral head (ONFH) in patients with FNF after internal fixation.

METHODS

We retrospectively collected preoperative, intraoperative, and postoperative clinical data of patients with FNF in 4 hospitals in Shanghai and followed up the patients for more than 2.5 years. A total of 259 patients with 43 variables were included in the study. The data were randomly divided into a training set (181/259, 69.8%) and a validation set (78/259, 30.1%). External data (n=376) were obtained from a retrospective cohort study of patients with FNF in 3 other hospitals. Least absolute shrinkage and selection operator regression and the support vector machine algorithm were used for variable selection. Logistic regression, random forest, support vector machine, and eXtreme Gradient Boosting (XGBoost) were used to develop the model on the training set. The validation set was used to tune the model hyperparameters to determine the final prediction model, and the external data were used to compare and evaluate the model performance. We compared the accuracy, discrimination, and calibration of the models to identify the best machine learning algorithm for predicting ONFH. Shapley additive explanations and local interpretable model-agnostic explanations were used to determine the interpretability of the black box model.

RESULTS

A total of 11 variables were selected for the models. The XGBoost model performed best on the validation set and external data. The accuracy, sensitivity, and area under the receiver operating characteristic curve of the model on the validation set were 0.987, 0.929, and 0.992, respectively. The accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve of the model on the external data were 0.907, 0.807, 0.935, and 0.933, respectively, and the log-loss was 0.279. The calibration curve demonstrated good agreement between the predicted probability and actual risk. The interpretability of the features and individual predictions were realized using the Shapley additive explanations and local interpretable model-agnostic explanations algorithms. In addition, the XGBoost model was translated into a self-made web-based risk calculator to estimate an individual's probability of ONFH.

CONCLUSIONS

Machine learning performs well in predicting ONFH after internal fixation of FNF. The 6-variable XGBoost model predicted the risk of ONFH well and had good generalization ability on the external data, which can be used for the clinical prediction of ONFH after internal fixation of FNF.

Paracetamol and Ibuprofen in the Treatment of Fever and Acute Mild-Moderate Pain in Children: Italian Experts' Consensus Statements

Fever and pain are challenging symptoms in children and adolescents and are common reasons for consultations in primary care and hospital. Paracetamol and ibuprofen are currently the only recommended drugs for treating fever in Italy, but the therapeutic approaches are discrepant in the different settings. In Italy, paracetamol and ibuprofen are the most prescribed analgesics for acute mild–moderate pain in children; however, their use is often inappropriate in that fever is over-treated and pain is under-treated. An Italian board of experts analyzed the motivations for the misalignment between daily practice and guidelines of fever and acute mild–moderate pain management of the territory and hospitals. The expert opinion consensus process underscored the appropriate use of paracetamol and ibuprofen according to clinical scenarios, patients’ profiles, and the safety features of the drugs. Although patients’ profiles can indicate different benefits from paracetamol or ibuprofen, critical issues of fever and acute mild–moderate pain management persist in primary care and hospitals. These expert opinion consensus statements can be an across-the-board tool to harmonize the routine practice between the territory and hospitals, especially under special conditions (at-risk for dehydration, coagulation disorder patients, etc.). It can also promote educational activity about fever and acute mild–moderate pain management to enhance the milestones already achieved by Italian pediatricians.

Usefulness of a global rating change scale for contact lens discomfort evaluation

OBJECTIVES

To evaluate the usefulness of a global rate of change scale (GRCS) to detect variations in contact lens discomfort (CLD).

METHODS

Symptomatic contact lens (CL) wearers were recruited according to the 'Contact Lens Dry Eye Questionnaire-8' (CLDEQ-8). At the baseline visit, subjects scored their comfort following insertion of their habitual CL using a 0-100 visual analogue scale (VAS). After 4-10 h of CL wear, comfort was again self-evaluated with the VAS and with a GRCS (range, -50 to +50). Then, a daily disposable CL (DDCL) was fitted. After one month of DDCL wear, a follow-up visit was conducted where the same evaluations as the baseline visit were performed. Changes in comfort were estimated using a Student's t-test for normal variables and the Friedman test for multiple comparisons of non-parametric variables. Internal responsiveness was measured by calculating the standardised response mean. Agreement between scales was estimated by the intraclass correlation coefficient (ICC).

RESULTS

Twenty-nine (22 females and 7 males) CL wearers with a mean age of 23.4 ± 5.4 years participated in the study. There was a significant decrease in comfort at both visits detected by the GRCS (baseline = -13.58 ± 17.48, p < 0.001; follow up = -6.86 ± 12.69, p = 0.007). However, the VAS did not detect that change, either at baseline (insertion = 64.28 ± 18.72 vs removal = 52.89 ± 17.64, p = 1.000) or follow-up visit (insertion = 81.97 ± 12.91 vs removal = 76.48 ± 16.02, p = 1.000). Comfort at insertion and removal times was significantly higher with the DDCL (p = 0.008 at insertion and p = 0.004 at removal). The standardised response mean was greater with the GRCS than the VAS at baseline (0.78 vs 0.63) and follow-up (0.54 vs 0.37) visits. Agreement between both scales was moderate and significant (p < 0.001) for both visits, ICC: 0.674 (95 % confidence interval (CI):0.411-0.833) (baseline) and 0.652 (95 % CI:0.377-0.821) (follow-up visit).

CONCLUSIONS

The GRCS can detect slight changes in CL wear comfort and shows higher responsiveness than the VAS. This subjective scale can allow detection of changes in comfort in a simple and quick way.

Severe abrupt (thunderclap) non-traumatic headache at the pediatric emergency department - a retrospective study

BACKGROUND

Adult abrupt severe non-traumatic headache (thunderclap) is often related to serious underlying etiologies such as subarachnoid hemorrhage. However, data are sparse regarding thunderclap headache in the pediatric population.

OBJECTIVE

The aim of the study was to evaluate the prevalence, characteristics and causes of thunderclap headache in the pediatric and adolescent population, aged 6-18 years, presenting to a pediatric emergency department.

METHODS

The electronic database of a tertiary care pediatric emergency department was searched for children presenting with acute headache during 2016-2018. Headache severity was defined by pain scales, either a visual analogue scale or by the Faces Pain Scale-Revised.

RESULTS

Thunderclap headache was diagnosed in 19/2290 (0.8%) of the included patients, all of them with a pain score of 10/10. All the patients had a benign course. Primary headache was diagnosed in 15/19 (78.9%), six patients had migraine and eight were diagnosed with primary thunderclap headache. Four of the 19 patients were diagnosed with secondary headache: three with infectious causes and one with malignant hypertension.

CONCLUSIONS

Thunderclap headache is rare among children and adolescents presenting to the emergency department. This headache is generally of a primary origin. Extensive evaluation is still needed to rule out severe diagnosis problems.

Exercise Programs Targeting Scapular Kinematics and Stability Are Effective in Decreasing Neck Pain: A Critically Appraised Topic

Clinical Scenerio: Neck pain is a costly symptom in both civilian and military worlds. While traditional treatments include deep neck flexor stabilizing exercises, manual therapy, electrical therapy, and other nonsurgical interventions, scapular orientation and stability training has emerged as a possible tool to reduce neck pain severity. Methods that can be coached at a distance could be of value in virtual appointments or circumstances where access to a qualified manual therapist is limited. Focused Clinical Question: What is the effectiveness of including exercise programs targeting scapular kinematics and stability to decrease neck pain? Summary of Key Findings: Exercise programs targeting scapular kinematics and stability, with coaching and individualized progressions, appear to reduce neck pain severity. Clinical Bottom Line: Evidence supports the inclusion of exercises for scapular kinematics and stability at a prescription of 3 sessions per week, with a duration of 4 or 6 weeks. Exercise programs should include a "learning" or coaching phase to ensure exercises are performed as intended, and exercise progressions should be based on participant ability rather than predetermined timelines. Further research is needed to better understand the benefits of this potential strategy and the statistical impact of scapular-focused exercise interventions on neck pain in specific populations like military and athletes. Strength of Recommendation: There is 'Fair' to 'Good' evidence from 2 level 1b single-blind randomized control studies and 1 level 2b pre-post test control design study supporting the inclusion of exercise programs targeting scapular kinematics and stability to decrease chronic neck pain severity.

A standard set of outcome measures for the comprehensive assessment of osteogenesis imperfecta

BACKGROUND

Osteogenesis Imperfecta (OI) is a genetic disorder also known as 'brittle bone disease'. The clinical manifestation of OI shows a wide variation. Therefore, care for patients with OI requires an interdisciplinary approach. The effectiveness of particular interventions and treatment protocols of interdisciplinary teams is not clear due to a non-standardized and wide variation of patient outcomes thus making the comparison of outcome measures available in the literature difficult. It is only by agreeing on a common, standard set of outcome measures for the comprehensive appraisal of OI that comparisons across interdisciplinary treatment centers for OI will be possible in the future.

METHODS

The Key4OI international interdisciplinary working group of 27 members used a consensus-driven modified Delphi approach to develop a set of global outcome measures for patients with OI. The International Classification of Functioning, Disability and Health (ICF), was used to define domains and organize the outcomes from the literature search. After reviewing the outcomes extracted from the literature, trials and registries, the working group agreed on a final selection of domains and their definition (ICF definition as well as a lay description). These domains were then presented to the focus groups who prioritized the outcome domains by taking into account the items important to the OI community. All content was collected and analyzed and final domains were determined. A consensus of appropriate measuring instruments for each domain was reached with Delphi rounds. The entire approach was in line with the International Consortium for Health Outcomes Measurement ICHOM methodology.

RESULTS

More than 400 different outcome measures were identified in our literature search. After three Delphi rounds, 24 domains were selected. After the focus group sessions, the number of domains were reduced to 15. A consensus was reached on the measuring instruments to cover these domains for both children and adults.

CONCLUSION

The Key4OI project resulted in standard set of outcome measures focused on the needs and wishes of individuals with OI and their families. This outcome set will enable healthcare teams and systems to compare and to improve their care pathways and quality of care worldwide. Further studies are needed to evaluate the implementation of this standardized outcome set.

Validation of Outcome Instruments for Pediatric Postthrombotic Syndrome: Introducing the Peds-VEINES-QOL, a New Health-Related Quality of Life Instrument

BACKGROUND

 There is need for validated outcome measures for postthrombotic syndrome (PTS) following pediatric venous thromboembolism (VTE), with a focus on quality of life (QoL).

AIMS

 This article assesses reliability and validity of two PTS and two QoL scales for children following lower extremity VTE.

METHODS

 Pediatric patients following lower extremity VTE were recruited from three thrombosis clinics. The Manco-Johnson (MJ) and the modified Villalta (MV) PTS scales were compared with each other and with the generic pediatric health-related QoL, PedsQL, and a newly developed pediatric venous-specific QoL, the Peds-VEINES-QOL.

RESULTS

 Eighty children following VTE and 60 healthy control children were enrolled. Internal consistency measured by Cronbach's α was high for the two QoL scales, and moderate for the two PTS scales. Inter-rater reliability using intraclass correlation coefficients was moderate to high for the MJ, MV, and Peds-VEINES-QOL, and moderate for the PedsQL. Evidence of high internal consistency by Cronbach's α coefficients, and moderate to high interitem correlations support the premise that a single construct was measured by each instrument. Correlations between the four instruments indicate convergent validity.

CONCLUSION

 The MJ and MV scales detect similar outcomes in children following VTE. As used, the MJ is slightly more sensitive to QoL because a positive diagnosis requires pain which is the leading factor in reduced QoL following deep vein thrombosis. When using the MV, a requirement for pain or abnormal use to diagnose PTS would make the MV a better predictor of QoL.

Use of a Flexible Catheter for the Administration of Subcutaneous Insulin in Diabetic Ketoacidosis: A Feasibility Controlled Clinical Trial

BACKGROUND

Although intravenous insulin administration is the standard of care in diabetic ketoacidosis (DKA), subcutaneous insulin administration could be a suitable alternative in resource-limited settings, but pain caused by hourly insulin applications are limiting factors for using it, especially in children. We aimed to assess whether the use of a flexible subcutaneous catheter improves comfort in patients with DKA compared with the usual hourly injections' treatment. We also compared the evolution of metabolic variables in patients with DKA using both insulin administration systems.

METHODS

Randomized feasibility controlled open trial, comparing 2 ways (flexible catheter and steel needle) for the initial insulin administration in children with DKA, who were randomly selected to receive subcutaneous insulin by a flexible catheter or using standard needles. The main outcome was pain, assessed hourly and secondary outcome time to achieve ketoacidosis resolution.

RESULTS

Twenty subjects were included (10 by group). There were no differences between groups in baseline lab values (glycemia, urea, sodium, bicarbonate and pH). Pain assessment at first insulin administration was significantly lower in the intervention group (4.5 vs 0 points; P = 0.001). Similar differences between both treatment arms were observed in every pain assessment. There were no differences between groups regarding the time elapsed to achieve ketoacidosis resolution. (11.4±4.3 vs 16±8.4; P = 0.12). No adverse events or DKA complications were observed.

CONCLUSIONS

The use of a flexible catheter reduced the pain associated with subcutaneous insulin administration in nonsevere DKA. The flexible subcutaneous catheter could be a safe alternative for the treatment of uncomplicated DKA in resource-limited settings.

Minimising Immunisation Pain of childhood vaccines: The MIP pilot study

AIM

Pain associated with immunisations can result in distress and/or anxiety for children and parents. We assessed the feasibility and acceptability of two novel devices; Coolsense (cold) and Buzzy (vibration ± cooling pads) versus standard care to minimise pain during immunisations. We also evaluated compliance to the devices and parent's perception of the effectiveness of the devices/standard care for minimising pain during immunisation.

DESIGN

Open label, pilot, randomised controlled trial (RCT).

METHODS

Forty children aged 3.5 to 6 years attending an Immunisation Centre at The Royal Children's Hospital in Melbourne, Australia, were randomised (1:1:1:1) into four groups: (i) Coolsense plus standard care; (ii) Buzzy with cold plus standard care; (iii) Buzzy without cold plus standard care; and (iv) Standard care alone (distraction with bubbles).

RESULTS AND ANALYSIS

Recruitment was completed in 12 days. Seventy percent were compliant with Buzzy (±cold), 82% with Coolsense, and 60% with standard care. Buzzy (with cold) was identified as effective by 70% of parents, Coolsense by 64%, Buzzy without cold by 50% and standard care by 60%.

CONCLUSIONS

This pilot study demonstrated feasibility. A larger RCT is needed to provide definitive evidence to inform best practice for minimising immunisation pain in young children.

Preanesthetic nebulized ketamine vs preanesthetic oral ketamine for sedation and postoperative pain management in children for elective surgery: A retrospective analysis for effectiveness and safety

Preoperative anxiety is a major problem in children leading to a poor outcome. Preanesthetic oral ketamine is generally used in children but has less bioavailability due to the first-pass effect. Even ketamine has an unpleasant taste. Preanesthetic inhaled ketamine is also reported effective and safe in children. The objectives of the study were to compare the effectiveness and safety of preanesthetic nebulized ketamine against preanesthetic oral ketamine for sedation and postoperative pain management in children.Children received 10 mg/kg oral ketamine (children received preanesthetic oral ketamine [OK cohort], n = 142), or nebulized with 3 mg/kg ketamine (children were preanesthetic nebulized with ketamine [NK cohort], n = 115), or received apple juice (children suspectable to preoperative ketamine and received apple juice only [OA cohort], n = 126) before anesthesia for elective surgery. Data regarding preoperative hemodynamic parameters, sedation score measurements, postoperative pain management, postoperative nausea and vomiting management, and postoperative complications were collected and analyzed.Preoperative hemodynamic parameters for oral and nebulized ketamine administration were stable. Nebulized ketamine was provided higher sedation than apple juice (P = .002, q = 4.859) and oral ketamine (P = .002, q = 3.526). Children of NK cohort had required fewer fentanyl consumption until discharge than those of OA (55.45 ± 7.19 μG/ child vs 65.15 ± 15.24 μG/ child, P < .0001, q = 9.859) and OK (55.45 ± 7.19 μG/child vs 60.19 ± 8.12 μG/child, P < .0001, q = 4.953) cohorts. Children of the NK cohort had consumed higher ondansetron syrup than those of the OA cohort but fewer than those of the OK cohort until discharge. Gastrointestinal side effects were reported in the OK cohort, and nose irritation and drowsiness were reported in the NK cohort.Like preanesthetic oral ketamine, preanesthetic inhaled ketamine also has safety for children. Preanesthetic inhaled ketamine can provide effective sedation in low doses during operation than preanesthetic oral ketamine.Level of evidence: III.

A Study on the Evaluation of a Risk Score of Osteonecrosis of the Femoral Head Based on Survival Analysis

BACKGROUND

This study aimed at developing a risk score predicting the probability of developing an osteonecrosis of the femoral head (ONFH) in patients with femoral neck fracture within 3 years after closed reduction internal fixation and evaluating its performance, clinical utility, and internal validity.

METHODS

A retrospective follow-up study of 378 newly injured femoral neck fracture patients treated with 3 partially threaded parallel cannulated screws in 3 hospitals in Shanghai from March 2013 to January 2017 was performed. The patients were divided into development (n = 284) and validation (n = 94) cohorts. The risk score was constructed by Cox regression analysis in a form of nomogram. The performance and clinical utility were illustrated by box plots, calibration plots, and decision curve analysis.

RESULTS

Eighty-three of 378 patients had developed ONFH within 3 years. Garden alignment index, time to surgery, preoperative displace, impaction, and postoperative malposition were used as predictors to construct the risk score in a form of nomogram. In the development and validation cohort, the concordance index was 0.96 and 0.94, respectively; the discrimination slope was 0.51 and 0.47, respectively. In both cohorts, the calibration slopes and intercepts were 1 and 0, respectively. The risk score was clinically useful between the risk threshold of 0% and 88%. The performance and utility in the validation data illustrated good repeatability.

CONCLUSION

The risk score had satisfactory discrimination and calibration performance and demonstrated clinical utility with good internal validity. It managed to distinguish high-risk groups for post-traumatic ONFH.

Clinical efficacy of intravenous anesthesia on breast segmental surgery and its effects on oxidative stress response and hemodynamics of patients

This study was designed to investigate the clinical efficacy of intravenous anesthesia on breast segmental surgery and the effects on hemodynamics of patients. A total of 267 patients were collected as research subjects. These patients underwent breast segmental surgery in Chun'an First People's Hospital from March 2015 to September 2018. Among them, 137 patients undergoing intravenous anesthesia were the research group, and 130 patients undergoing inhalation anesthesia were the control group. The following parameters were recorded: Clinical efficacy, postoperative adverse conditions, hemodynamic indicators including systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR). Visual analogue scale (VAS) was used to observe the analgesic effect of the two groups, the mental state of patients in the two groups was observed by mini-mental state examination (MMSE) scoring method, and systemic evaluation was made by oxidative stress (OS) reaction indicators. The MMSE scores of the two groups decreased one day after surgery, but the score in the research group was higher than that in the control group (P<0.05). The levels of SBP and DBP at T1 and T2 in the control group were significantly higher than those in the research group (P<0.05). HR of research group at T1 and T2 was lower than that at T0 and that at corresponding time of control group (P<0.05). The incidence rate of postoperative adverse reactions in the research group was significantly lower than that in the control group (P<0.05). In conclusion, intravenous anesthesia for breast segmental surgery can reduce the occurrence of adverse reactions after surgery, with complete sedation and analgesia. Patients were able to wake up quickly and stably after surgery, and their cognitive function and OS recovered rapidly. However, due to the great impact on hemodynamics during surgery, attention should be paid to maintain hemodynamic stability during surgery to avoid hypotension and bradycardia.

Spatial aspects of pain modulation are not disrupted in adolescents with migraine

OBJECTIVE

To compare spatial pain modulation capabilities between adolescents with and without migraine.

BACKGROUND

Conditioned pain modulation (CPM) responses at the leg are similar in adolescents with versus without migraine. However, the anatomical region of testing may affect spatial pain modulation capabilities as differences in nociceptive processing between patients with migraine and healthy controls are found in local areas that are near the site of clinical pain but not in nonlocal areas. This study aimed to examine spatial pain modulation capabilities tested by the CPM paradigm using test stimulus applied to a local body area.

METHODS

Nineteen adolescents with migraine (age 14.9 ± 2.3, mean ± SD; 16 female) and 20 healthy adolescents (age 13.8 ± 2.5, mean ± SD; 16 female) completed this case-control study at Cincinnati Children's Hospital Medical Center. Pressure pain thresholds (PPT) were assessed at the trapezius before and during immersion of the foot in a cold water bath (8°C).

RESULTS

In the migraine group (146.0 ± 79.1, mean ± SD), compared to healthy controls (248.0 ± 145.5, mean ± SD), significantly lower PPT (kilopascal) values were found (estimate = 124.28, 95% CI: 58.98, 189.59, p < 0.001; effect size: d = 1.40). No differences between the groups were found for pain intensity and unpleasantness ratings of cold-water immersion nor the CPM response.

CONCLUSIONS

This study found altered ascending nociceptive processing of mechanical stimuli at the neck in adolescents with migraine. However, endogenous pain modulatory mechanisms were functional and not altered. In light of other studies, impairments in inhibitory control may not be involved in migraine pathophysiology in pediatric patients regardless of stimulus location.

Non-steroidal or opioid analgesia use for children with musculoskeletal injuries (the No OUCH study): statistical analysis plan

Background

Pediatric musculoskeletal injuries cause moderate to severe pain, which should ideally be addressed upon arrival to the emergency department (ED). Despite extensive research in ED-based pediatric pain treatment, recent studies confirm that pain management in this setting remains suboptimal. The No OUCH study consist of two complementary, randomized, placebo-controlled trials that will run simultaneously for patients presenting to the ED with an acute limb injury and a self-reported pain score of at least 5/10, measured via a verbal numerical rating scale (vNRS). Caregiver/parent choice will determine whether patients are randomized to the two-arm or three-arm trial. In the two-arm trial, patients will be randomized to receive either ibuprofen alone or ibuprofen in combination with acetaminophen. In the three-arm trial, patients can also be randomized to a third arm where they would receive ibuprofen in combination with hydromorphone. This article details the statistical analysis plan for the No OUCH study and was submitted before the trial outcomes were available for analysis.

Methods/design

The primary endpoint of the No OUCH study is self-reported pain at 60 min, recorded using a vNRS. The principal safety outcome is the presence of any adverse event related to study drug administration. Secondary effectiveness endpoints include pain measurements using the Faces Pain Scale-Revised and the visual analog scale, time to effective analgesia, requirement of a rescue analgesic, missed fractures, and observed pain reduction using different definitions of successful analgesia. Secondary safety outcomes include sedation measured using the Ramsay Sedation Score and serious adverse events. Finally, the No OUCH study investigates the reasons given by the caregiver for selecting the two-arm (Non-Opioid) or three-arm (Opioid) trial, caregiver satisfaction, physician preferences for analgesics, and caregiver comfort with at-home pain management.

Discussion

The No OUCH study will inform the relative effectiveness of acetaminophen and hydromorphone, in combination with ibuprofen, and ibuprofen alone as analgesic agents for patients presenting to the ED with an acute musculoskeletal injury. The data from these trials will be analyzed in accordance with this statistical analysis plan. This will reduce the risk of producing data-driven results and bias in our reported outcomes.

Optic Nerve Sheath Diameter and Retinal Artery Resistive Index Measurements with Bedside Ophthalmic Ultrasound in Pediatric Patients with Pseudotumor Cerebri Syndrome

Pseudotumor cerebri syndrome (PTCS) is characterized by raised intracranial pressure (ICP) with no neuroradiological abnormalities. Ocular ultrasound has been in use to measure optic nerve sheath diameter (ONSD), and retinal artery Doppler indices have been used for indirect assessment of ICP by pediatric intensivists. Here, we aimed to evaluate the correlation of the lumbar puncture (LP) opening pressure with the ultrasonographic ONSD and retinal resistive index (RRI) measures in patients with PTCS. And we wanted to find an answer to the following question: Can ultrasonographic ONSD measures serve as a follow-up tool in patients with PTCS? A prospective, single-center, case-control study was performed by pediatric intensive care and pediatric neurology departments. A total of 7 patients with PTCS were evaluated as patient group and 15 healthy children were evaluated as control group. The mean age of patient group was 138.8 ± 43.7 months. The mean right ONSD was 6.7 ± 0.5 mm and the mean left ONSD was 6.7 ± 0.6 mm. The mean right RRI value was 0.73 ± 0.03 and the mean left RRI was 0.73 ± 0.09. For the patient group, ONSD and RRI values of both eyes were statistically significant higher values than for the control group. The mean LP opening pressure was 56.57 ± 16.36 cmH ₂ O. We detected strong, positive, and statistically significant correlations between the LP opening pressure and ONSD baseline measures for both the right eye ( r  = 0.882, p  = 0.009) and the left eye ( r  = 0.649, p  = 0.004). There was no correlation between opening pressure in LP and RRI measurements. We detected a statistically significant decrease in the right ONSD and left ONSD values and visual analog scale scores at the third-month follow-up. Our study results demonstrate that ultrasonographic ONSD measurements can be used as a noninvasive tool for assessment of the ICP at first admission and can be used as a follow-up tool in PTSC patients.

Long-Term Posttraumatic Stress Following Accidental Injury in Children and Adolescents: Results of a 2-4-Year Follow-Up Study

In this study, we determined the long-term prevalence of posttraumatic stress disorder (PTSD) in children and adolescents after accidental injury and gained insight into factors that may be associated with the occurrence of PTSD. In a prospective longitudinal study, we assessed diagnosed PTSD and clinically significant self-reported posttraumatic stress symptoms (PTSS) in 90 children (11–22 years of age, 60% boys), 2–4 years after their accident (mean number of months 32.9, SD 6.6). The outcome was compared to the first assessment 3 months after the accident in 147 children, 8–18 years of age. The prevalence of PTSD was 11.6% at first assessment and 11.4% at follow-up. Children with PTSD or PTSS reported significantly more permanent physical impairment than children without. Children who completed psychotherapy had no symptoms or low levels of symptoms at follow-up. Given the long-term prevalence of PTSD in children following accidents, we recommend systematic monitoring of injured children. The role of possible associated factors in long-term PTSS needs further study.

Study protocol for two complementary trials of non-steroidal or opioid analgesia use for children aged 6 to 17 years with musculoskeletal injuries (the No OUCH study)

INTRODUCTION

Musculoskeletal (MSK) injuries are a frequent cause for emergency department (ED) visits in children. MSK injuries are associated with moderate-to-severe pain in most children, yet recent research confirms that the management of children's pain in the ED remains inadequate. Clinicians are seeking better oral analgesic options for MSK injury pain with demonstrated efficacy and an excellent safety profile. This study aims to determine the efficacy and safety of adding oral acetaminophen or oral hydromorphone to oral ibuprofen and interpret this information within the context of parent/caregiver preference.

METHODS AND ANALYSIS

Using a novel preference-informed complementary trial design, two simultaneous trials are being conducted. Parents/caregivers of children presenting to the ED with acute limb injury will be approached and they will decide which trial they wish to participate in: an opioid-inclusive trial or a non-opioid trial. Both trials will follow randomised, double-blind, placebo-controlled, superiority-trial methodology and will enrol a minimum of 536 children across six Canadian paediatric EDs. Children will be eligible if they are 6 to 17 years of age and if they present to the ED with an acute limb injury and a self-reported verbal Numerical Rating Scale pain score ≥5. The primary objective is to determine the effectiveness of oral ibuprofen+oral hydromorphone versus oral ibuprofen+oral acetaminophen versus oral ibuprofen alone. Recruitment was launched in April 2019.

ETHICS AND DISSEMINATION

This study has been approved by the Health Research Ethics Board (University of Alberta), and by appropriate ethics boards at all recruiting centres. Informed consent will be obtained from parents/guardians of all participants, in conjunction with assent from the participants themselves. Study data will be submitted for publication regardless of results. This study is funded through a Canadian Institutes of Health Research grant.

Children Listening to Music or Watching Cartoons During ER Procedures: A RCT

OBJECTIVE

This study aims to determine if listening to music and watching cartoons are effective to distract children from pain and distress during procedures in the emergency room (ER).

METHODS

This study is a single-center, 3-armed, superiority randomized controlled trial comparing listening to music, watching cartoons, and standard care during ER procedures in children aged 3-13 years. The primary outcome was pain measured from video footage with the Alder Hey Triage Pain Score (AHTPS). Children older than 4 years self-reported pain with the Faces Pain Scale-Revised (FPS-R). The secondary outcome was distress measured with the Observational Scale of Behavioral Distress-revised (OSBD-r). Another indicator of distress was heart rate.

RESULTS

Data of 191 participants were analyzed for the 3 groups: music (n = 75), cartoon (n = 62), and control (n = 54). The median age was 7.3 years (4.9-9.7). In multivariable analysis, pain assessed with the AHTPS was significantly lower (B = -1.173, 95% confidence interval -1.953, -0.394, p = .003) in the music group than in the control groups. Across the 3 groups, 108 children self-reported pain with the FPS-R after the procedure. The scores were lowest in the music group, but the differences between groups were not significant (p = .077). OSBD-r distress scores assigned during the procedures were not significantly different between the 3 groups (p = .55). Heart rate directly after the procedure was not statistically significantly different between the 3 groups (p = .83).

CONCLUSIONS

Listening to recorded music is a beneficial distraction for children experiencing pain during ER procedures, whereas watching cartoons did not seem to reduce pain or distress.

User testing of the psychometric properties of pictorial-based disability assessment Longshi Scale by healthcare professionals and non-professionals: a Chinese study in Shenzhen

OBJECTIVE

The aim of this study was to validate a novel pictorial-based Longshi Scale for evaluating a patient's disability by healthcare professionals and non-professionals.

DESIGN

Prospective study.

SETTING

Rehabilitation departments from a grade A, class 3 public hospital, a grade B, class 2 public hospital, and a private hospital and seven community rehabilitation centers.

SUBJECTS

A total of 618 patients and 251 patients with functional disabilities were recruited in a two-phase study, respectively.

MAIN MEASURES

Outcome measure: pictorial scale of activities of daily living (ADLs, Longshi Scale). Reference measure: Barthel Index. The Spearman correlation coefficient was used to analyze the validity of Longshi Scale against Barthel Index.

RESULTS

In phase 1 study, from March 2016 to August 2016, the results demonstrated that the Longshi Scale was both reliable and valid (intraclass correlation coefficient based on two-way random effect (ICC_2,1) = 0.877-0.974 for intra-rater reliability; ICC_2,1 = 0.928-0.979; κ = 0.679-1.000 for inter-rater reliability; intraclass correlation coefficient based on one-way random effect (ICC_1,1) = 0.921-0.984 for test-retest reliability and Spearman correlation coefficient = 0.836-0.899). In the second phase, in March 2018, results further demonstrated that the Longshi Scale had good inter-rater and intra-rater reliability among healthcare professionals and non-professionals including therapists, interns, and personal care aids (ICC_1,1 = 0.822-0.882 on Day 1; ICC_1,1 = 0.842-0.899 on Day 7 for inter-rater reliability). In addition, the Longshi Scale decreased assessment time significantly, compared with the Barthel Index assessment (P < 0.01).

CONCLUSION

The Longshi Scale could potentially provide an efficient way for healthcare professionals and non-professionals who may have minimal training to assess the ADLs of functionally disabled patients.

Machine learning methods for automatic pain assessment using facial expression information: Protocol for a systematic review and meta-analysis

INTRODUCTION

Prediction of pain using machine learning algorithms is an emerging field in both computer science and clinical medicine. Several machine algorithms were developed and validated in recent years. However, the majority of studies in this topic was published on bioinformatics or computer science journals instead of medical journals. This tendency and preference led to a gap of knowledge and acknowledgment between computer scientists who invent the algorithm and medical researchers who may use the algorithms in practice. As a consequence, some of these prediction papers did not discuss the clinical utility aspects and were causally reported without following related professional guidelines (e.g., TRIPOD statement). The aim of this protocol is to systematically summarize the current evidences about performance and utility of different machine learning methods used for automatic pain assessments based on human facial expression. In addition, this study is aimed to demonstrate and fill the knowledge gap to promote interdisciplinary collaboration.

METHODS AND ANALYSIS

We will search all English language literature in the following electronic databases: PubMed, Web of Science and IEEE Xplore. A systematic review and meta-analysis summarizing the accuracy, interpretability, generalizability, and computational efficiency of machine learning methods will be conducted. Subgroup analyses by machine learning method types will be conducted.

TIMELINE

The formal meta-analysis will start on Jan 15, 2019 and expected to finish by April 15, 2019.

ETHICS AND DISSEMINATION

Ethical approval will be exempted or will not be required because the data collected and analyzed in this meta-analysis will not be on an individual level. The results will be disseminated in the form of an official publication in a peer-reviewed journal and/or presentation at relevant conferences.

Paediatric Pain Medicine: Pain Differences, Recognition and Coping Acute Procedural Pain in Paediatric Emergency Room

Paediatric pain and its assessment and management are challenging for medical professionals, especially in an urgent care environment. Patients in a paediatric emergency room (PER) often undergo painful procedures which are an additional source of distress, anxiety, and pain. Paediatric procedural pain is often underestimated and neglected because of various myths, beliefs, and difficulties in its evaluation and treatment. However, it is very different from other origins of pain as it can be preventable. It is known that neonates and children can feel pain and that it has long-term effects that last through childhood into adulthood. There are a variety of pain assessment tools for children and they should be chosen according to the patient’s age, developmental stage, communication skills, and medical condition. Psychological factors such as PER environment, preprocedural preparation, and parental involvement should also be considered. There are proven methods to reduce a patient’s pain and anxiety during different procedures in PER. Distraction techniques such as music, videogames, virtual reality, or simple talk about movies, friends, or hobbies as well as cutaneous stimulation, vibration, cooling sprays, or devices are effective to alleviate procedural pain and anxiety. A choice of distraction technique should be individualized, selecting children who could benefit from nonpharmacological pain treatment methods or tools. Nonpharmacological pain management may reduce dosage of pain medication or exclude pharmacological pain management. Most nonpharmacological treatment methods are cheap, easily accessible, and safe to use on every child, so it should always be a first choice when planning a patient’s care. The aim of this review is to provide a summary of paediatric pain features, along with their physiology, assessment, management, and to highlight the importance and efficacy of nonpharmacological pain management in an urgent paediatric care setting.
