Longitudinal evaluation of patient-reported outcomes measurement information systems measures in pediatric chronic pain

Impact of Spinal Deformity Characteristics on Patient-reported Outcome Measurement Information System Scores in Patients With Idiopathic Scoliosis Undergoing Posterior Spinal Fusion

INTRODUCTION

The impact of posterior spinal fusion (PSF) on physical function and pain and mental health in pediatric patients as quantified by the Patient-Reported Outcomes Measurement Information System (PROMIS), developed by the National Institute of Health, is largely unknown. The purpose of this study is to report the changes of PROMIS scores for upper extremity (UE), pain interference (PI), mobility (MOB), and peer relationships (PR) after PSF in patients with idiopathic scoliosis (IS), compare postoperative changes in PROMIS PI and Scoliosis Research Society-30 pain scores, and evaluate associations between curve characteristics and PROMIS scores.

METHODS

A retrospective cohort of 122 patients (<18 years old) who underwent PSF for IS was identified through electronic medical record search. PROMIS scores were obtained preoperatively and 6 weeks, 6 months, 1 years, 2 years, and 3 years postoperatively.

RESULTS

The mean age of the cohort was 14.2 ± 1.6 years, and the mean Cobb angle was 62.9 ± 13.8° at surgery. Eighty patients had preoperative PROMIS data. UE and MOB scores were statistically lower at 6 weeks and 6 months postoperatively and returned to baseline with a longer follow-up. PI scores were significantly lower at 1 and 2 years postoperatively. PR was unchanged up to 2 years postoperatively and then showed significant improvement. There was a statistically significant negative relationships between lowest instrumented vertebra and PROMIS UE and MOB scores at 6 weeks and 1 year postoperatively, but not at a longer follow-up. There were no significant differences noted in PI and PR PROMIS scores and lowest instrumented vertebra. PROMIS scores were not statistically associated with the Lenke Classification, number of vertebral levels fused, or percentage coronal correction.

DISCUSSION

Changes in PROMIS functional domains (UE and MOB) postoperatively normalize at longer follow-ups. Changes in PI and PR demonstrated improvements over preoperative values at 1 to 2 years postoperatively. Preoperative coronal and sagittal measures, and the percentage correction did not correlate with any PROMIS scores.

Executive Functioning in Youth With and Without Chronic Pain: A Comparative Analysis

OBJECTIVES

Preliminary research in youth with chronic pain suggests differences in attention and working memory, which has been similarly demonstrated in adults with chronic pain. There has been little research on other aspects of executive functioning (EF) in this population despite its critical role in problem solving, school functioning, and coping. This study aimed to examine differences in several aspects of EF between youth with chronic pain and a nonchronic pain comparison group using performance-based neuropsychological tests and a behavior rating scale.

MATERIALS AND METHODS

Participants completed ratings of pain; physical, emotional, social, and school functioning; sleep quality; medication; and a general intelligence screener. Standardized neuropsychological tests were used to examine EF with a focus on working memory, divided and alternating attention, inhibition, flexibility, incidental memory, and planning. A parent-report and self-report behavior rating of EF was also administered.

RESULTS

Recruitment from 2 tertiary-care pain clinics resulted in a sample of 26 youth with chronic pain (80.8% girls) and their parents. A comparison group of 30 youth without chronic pain and their parents were recruited from the community. Participants with chronic pain had significantly lower scores on several performance-based tests of working memory/divided attention, inhibition, and flexibility/alternating attention than the comparison group. Statistically significant group differences were also found on behavior ratings of emotion control, shifting, task initiation and completion, working memory, planning and organization, overall emotion and cognitive regulation as well as global EF. Covariate analysis was conducted in all analyses where there were significant group differences and several observed group differences remained.

DISCUSSION

This study is one of few multidimensional examinations of EF in youth with chronic pain, using a comprehensive neuropsychological test battery combined with behavior ratings. Our findings suggest EF differences in youth with chronic pain, across a variety of domains and may suggest risk for specific cognitive processing weaknesses in this population. Medical and educational teams should work toward identification, treatment, and compensatory support for EF within individualized pain management for youth.

Comparing the Measurement Properties and Preferability of Patient-reported Outcome Measures in Pediatric Rheumatology: PROMIS vs CHAQ

Objective

The Childhood Health Assessment Questionnaire (CHAQ), though widely used for assessments in pediatric rheumatology, has drawbacks, including low correlation to disease activity and ceiling effects. We sought to determine if any tools from the Patient Reported Outcomes Measurement Information System (PROMIS) improve on these shortcomings and/or are preferred by patients.

Methods

Patients 5–17 years of age with juvenile idiopathic arthritis ( JIA) or juvenile dermatomyositis ( JDM) were recruited from the rheumatology clinics at a Canadian children’s hospital. Participants completed the CHAQ, 3 PROMIS measures (pain interference, mobility, and physical activity), and underwent a standard clinical assessment.

Results

Fifty-two patients participated, 25 with JIA and 27 with JDM. None of the PROMIS measures suffered from ceiling effects, whereas the CHAQ Disability Index (DI) and pain visual analog scales both did, with 50% and 20% of patients achieving the best possible scores, respectively. The PROMIS mobility was moderately correlated to the CHAQ-DI (rs –0.60, 95% CI –0.75 to –0.40), and the PROMIS pain interference was strongly correlated to the CHAQ pain score (rs 0.65, 95% CI 0.43–0.80). No measures correlated with disease activity. Patients preferred the PROMIS to the CHAQ.

Conclusion

The PROMIS pain interference, mobility, and physical activity measures improve in some areas where the CHAQ is weak: they do not suffer from ceiling effects, and patients prefer the PROMIS tools. More work is needed to determine the correlation and responsiveness of the PROMIS tools to changes in disease activity over time before they should be widely adopted for clinical use.

Diagnostic uncertainty in pediatric chronic pain: nature, prevalence, and consequences

Introduction

Diagnostic uncertainty (DU), which is the perception that a label or explanation for a patient's health problem is missing or inaccurate, has been linked to distress, anxiety, and difficulty coping among adults with pain. This study examined the prevalence of DU among youth with chronic pain and their parents and the relation of parent and youth DU with youth pain, pain-related constructs, and health-related quality of life (HRQoL).

Methods

Participants included 174 youth with chronic pain (M _age = 14.28 years; 73% female) and one of their parents (91% mothers) recruited from a tertiary-level pediatric chronic pain program in Canada. Youth and parent DU was assessed using a brief measure of 3 empirically derived yes/no questions regarding whether the youth and parent had received a clear diagnosis/explanation for their/their child's pain and whether they believed there was something else happening with their/their child's pain that doctors had not yet found. Youth reported on their pain intensity, pain interference, pain catastrophizing, fear of pain, and HRQoL.

Results

Thirty-one percent of youth and 28% of parents experienced DU. Seventy percent of parents and youth were in agreement regarding their experience of DU. Youth DU was linked to higher youth catastrophic thinking about their pain. Parent DU was linked to greater youth pain interference and intensity and lower youth HRQoL.

Conclusion

Diagnostic uncertainty is experienced by nearly a third of youth with chronic pain and their parents and is linked to worse youth pain, pain catastrophizing, and HRQoL.

Risk models for predicting the health-related quality of life of caregivers of youth with gastrointestinal concerns

PURPOSE

To determine the usefulness of cumulative and additive risk models in predicting the healthy-related quality of life (HRQOL) of caregivers of youth with chronic gastrointestinal conditions.

METHODS

203 caregivers (82.8% mothers; 77.3% white) of youth (M = 11.27 years; 44.3% female; 78.8% White) completed self-report questionnaires focused on potential environmental, child health, and family risk factors that could impact caregiver HRQOL. Cumulative risk models, evaluating overall combined risk level, as well as an additive risk model, exploring individual risk variables, were evaluated.

RESULTS

Higher levels of cumulative risk were associated with poorer caregiver HRQOL after controlling for child and caregiver sex. A linear cumulative risk model was a better fit than a quadratic cumulative risk model for predicting caregiver HRQOL, while an additive model identified child HRQOL, child pain interference and family functioning as the most individually impactful risk variables.

CONCLUSION

This study illustrates the usefulness of both additive and cumulative risk approaches in identifying caregivers at risk for poor HRQOL. Provision of appropriate referrals and interventions based on the caregiver's risk factors can help protect caregiver quality of life and, in turn, benefit the care children with chronic conditions receive at home.

Clinical relevance of attentional biases in pediatric chronic pain: an eye-tracking study

ABSTRACT

Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

An International Collaborative Standardizing Patient-Centered Outcome Measures in Pediatric Facial Palsy

Importance

Standardization of outcome measurement using a patient-centered approach in pediatric facial palsy may help aid the advancement of clinical care in this population.

Objective

To develop a standardized outcome measurement set for pediatric patients with facial palsy through an international multidisciplinary group of health care professionals, researchers, and patients and patient representatives.

Design, Setting, and Participants

A working group of health care experts and patient representatives (n = 21), along with external reviewers, participated in the study. Seven teleconferences were conducted over a 9-month period between December 3, 2016, and September 23, 2017, under the guidance of the International Consortium for Health Outcomes Measurement, each followed with a 2-round Delphi process to develop consensus. This process defined the scope, outcome domains, measurement tools, time points for measurements, and case-mix variables deemed essential to a standardized outcome measurement set. Each teleconference was informed by a comprehensive review of literature and through communication with patient advisory groups. Literature review of PubMed was conducted for research published between January 1, 1981, and November 30, 2016.

Main Outcomes and Measures

The study aim was to develop the outcomes and measures relevant to children with facial palsy as opposed to studying the effect of a particular intervention.

Results

The 21 members of the working group included pediatric facial palsy experts from 9 countries. The literature review identified 1628 papers, of which 395 (24.3%) were screened and 83 (5.1%) were included for qualitative evaluation. A standard set of outcome measurements was designed by the working group to allow the recording of outcomes after all forms of surgical and nonsurgical facial palsy treatments among pediatric patients of all ages. Unilateral or bilateral, congenital or acquired, permanent or temporary, and single-territory or multiterritory facial palsy can be evaluated using this standard set. Functional, appearance, psychosocial, and administrative outcomes were selected for inclusion. Clinimetric and psychometric outcome measurement tools (clinician-, patient-, and patient proxy-reported) and time points for measuring patient outcomes were established. Eighty-six independent reviews of the standard set were completed, and 34 (85%) of the 40 patients and patient representatives and 44 (96%) of the 46 health care professionals who participated in the reviews agreed that the standard set would capture the outcomes that matter most to children with facial palsy.

Conclusions and Relevance

This international collaborative study produced a free standardized set of outcome measures for evaluating the quality of care provided to pediatric patients with facial palsy, allowing benchmarking of clinicians, comparison of treatment pathways, and introduction of value-based reimbursement strategies in the field of pediatric facial palsy.

A Pilot Study Examining Neural Response to Pain in Adolescents With and Without Chronic Pain

Introduction: Chronic pain is common in adolescence and is associated with both pain and prevalence of mental illness later in life. While previous functional neuroimaging work has informed knowledge of neural alterations associated with chronic pain, these findings have been primarily limited to adult samples, and it is unclear if similar patterns of altered brain activation are present in the developing adolescent brain.

Objectives: The purpose of this study was to pilot a noxious pressure task during functional neuroimaging to assess brain response to pain in adolescents with and without chronic pain.

Methods: Adolescents (ages 11–16) with (n = 9, 7 females) and without (n = 9, 7 females) chronic pain, matched on age, sex, IQ, and parental history of chronic pain, completed a noxious mechanical pressure task to assess subjective pain thresholds. This was followed by randomized presentation of subjective equivalent pressure applications (adolescents' pain 4/0–10), and two objectively equivalent pressures (0.25 and 1.5 kg/cm²), during functional magnetic resonance imaging, using an event-related task design.

Results: Findings revealed that adolescents with chronic pain demonstrated significantly greater activation in the posterior cingulate compared to controls. Further, all adolescents demonstrated significant pain-related brain response in brain regions implicated in pain neurocircuitry, as well as in several regions of the default mode network. Similar patterns of neural response were also noted during pain anticipation.

Conclusion: These findings are important for not only understanding the neurocircuitry involved in adolescent chronic pain, but may prove beneficial to future pain treatment efforts that seek to alter pain neurocircuitry.

Risk and Resilience in Pediatric Pain: The Roles of Parent and Adolescent Catastrophizing and Acceptance

OBJECTIVES

Both pediatric and parent pain catastrophizing and pain acceptance are key factors associated with pediatric pain outcomes; however, the interactive effects of these factors within the parent-child dyad have yet to be tested. The aims of this study were to examine: (1) the mediating role of child catastrophizing between parent catastrophizing and child outcomes (pain interference and mobility), (2) the mediating role of child acceptance between parent acceptance and child outcomes, and (3) whether child acceptance buffers the relation between parent catastrophizing and child catastrophizing, which in turn impacts child outcomes.

MATERIALS AND METHODS

Cross-sectional data from 324 youth with chronic pain ages 10 to 17 years (mean age=14.72, [SD=2.12]; 73.1% female; 59% Caucasian) and their parents were collected. Participants completed measures assessing pediatric Patient-Reported Outcome Measurement Information System (PROMIS) domains (mobility and pain interference), pain catastrophizing, pain acceptance, and child pain intensity. Mediation was conducted via 1000-draw bootstrap-adjusted analyses in Mplus.

RESULTS

Parent pain catastrophizing was indirectly associated with child pain interference via child catastrophizing but was not associated with mobility difficulties in the mediation model. Parent pain acceptance was indirectly associated with both child pain interference and mobility via child acceptance. We did not find evidence of child acceptance-buffering parent and child pain catastrophizing.

DISCUSSION

The findings of this study highlight the need for caregiver involvement in multidisciplinary treatments to mitigate risk and enhance resilience in youth with chronic pain.

Parental Proxy PROMIS Pain Interference Scores are Only Modestly Concordant With Their Child's Scores: An Effect of Child Catastrophizing

OBJECTIVES

Pediatric patients with chronic musculoskeletal conditions such as idiopathic scoliosis awaiting surgical correction can experience pain that interferes with their daily functioning. Reports of this interference are commonly gathered from patients through the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference Scale and through parent-proxy scores. However, the child and parent/caregiver reports vary. To provide appropriate treatment for young patients with pain, the nature of the discrepancies and under which circumstances the reports differ needs to be understood. This report offers new information on the level of concordance among parent and child report of pain interference within this patient population, and which parent and child characteristics may influence concordance rates.

METHODS

Youth (age=10 to 17 y) with a history of musculoskeletal disorders, including idiopathic scoliosis, under consideration for surgical correction of that scoliosis and parent/caregiver dyads (n=103) completed the PROMIS Pain Interference Scale during an orthopedic presurgical visit. The current data was taken from a larger study examining postsurgical pain among patients undergoing orthopedic surgical procedures to correct scoliosis. The purpose of the current study was to measure the degree of agreement between parent and child reports of pain interference and discovery of relationships among predictors of pain interference score correspondence among dyads.

RESULTS

Correspondence between parent/caregiver and child reports of pain interference was modest (intraclass correlation coefficient=0.530). In total, 46% of dyads had similar pain interference scores, whereas 24% of parents reported higher pain interference in comparison to their child, the remaining 30% reported lower pain interference in relation to their child's report. Among children where discrepancies appeared, using logistic regression models, only child catastrophizing scores were associated with differences in parent and child estimation of child's pain interference scores. No parental characteristics predicted discrepancies between dyad pain interference reports.

DISCUSSION

Parent-proxy and child reports generally correspond, but when discrepant, 24% of parents reported higher pain interference in relationship to the child report of pain interference and 31% noted less intense pain interference than their child's pain interference. Given these results, care should be taken when interpreting parent reports of child pain interference, especially when a child reports higher degrees of pain interference.

Acupressure to Reduce Treatment-Related Symptoms for Children With Cancer and Recipients of Hematopoietic Stem Cell Transplant: Protocol for a Randomized Controlled Trial

BACKGROUND

We describe the study design and protocol of a pragmatic randomized controlled trial (RCT) Acupressure for Children in Treatment for a Childhood Cancer (ACT-CC).

OBJECTIVE

To describe the feasibility and effectiveness of an acupressure intervention to decrease treatment-related symptoms in children in treatment for cancer or recipients of a chemotherapy-based hematopoietic stem cell transplant (HSCT).

DESIGN

Two-armed RCTs with enrollment of 5 to 30 study days.

SETTING

Two pediatric teaching hospitals.

PATIENTS

Eighty-five children receiving cancer treatment or a chemotherapy-based HSCT each with 1 parent or caregiver.

INTERVENTION

Patients are randomized 1:1 to receive either usual care plus daily professional acupressure and caregiver delivered acupressure versus usual care alone for symptom management. Participants receive up to 20 professional treatments.

MAIN OUTCOME

A composite nausea/vomiting measure for the child.

SECONDARY OUTCOMES

Child's nausea, vomiting, pain, fatigue, depression, anxiety, and positive affect.

PARENT OUTCOMES

Depression, anxiety, posttraumatic stress symptoms, caregiver self-efficacy, and positive affect. Feasibility of delivering the semistandardized intervention will be described. Linear mixed models will be used to compare outcomes between arms in children and parents, allowing for variability in diagnosis, treatment, and age.

DISCUSSION

Trial results could help childhood cancer and HSCT treatment centers decide about the regular inclusion of trained acupressure providers to support symptom management.

Pain is Associated With Increased Physical and Psychosocial Impairment in Youth With a History of Burn Injuries

Burn injuries are significantly painful and associated with physical and psychological impairment. However, little research to-date has examined the potential role of the subjective experience of pain in either physical or psychological impairment in this population. This may be particularly important to examine, given that the pain experience can often be a significant barrier to recovery in other pediatric populations. The current study examined the cross-sectional and predictive relationships between patient-reported experience of pain (operationalized as PROMIS pain interference and self-reported pain intensity) and physical and psychosocial outcomes. Data were gathered as part of the Burn Model System National Database (1994-2018) with the data request inclusive of pediatric self-report PROMIS measures, child PTSD, and post-traumatic growth symptoms assessed at 6- and 12-month postdischarge following initial injury. A total of 65 youth between the ages of 6 and 16 years at the time of their injury were included in the dataset. Correlational and regression analyses indicated that pain interference was cross-sectionally and longitudinally associated with decreased physical functioning, depressive symptoms, and peer relationships. Pain intensity was significantly associated with and predictive of physical functioning and pain interference. Results of the current study are an important first step in understanding the pain experience and associated outcomes in youth with a history of burn injuries. Future research is needed to further examine these relationships. PERSPECTIVE: This study presents preliminary findings from a national database on pain-related outcomes both cross-sectionally and longitudinally in youth with a history of burn injury. To-date, pain-related outcomes are poorly understood in this population and the results of this study serve to inform future research and treatment-related efforts.

Nausea exacerbates symptom burden, quality of life, and functioning in adolescents with functional abdominal pain disorders

BACKGROUND

Nausea frequently co-exists with functional abdominal pain disorders (FAPDs) and may be linked to a higher disease burden. This study aimed to prospectively compare multisystem symptoms, quality of life, and functioning in FAPDs with and without nausea.

METHODS

Adolescents ages 11-18 years fulfilling Rome III criteria for a FAPD were grouped by the presence or absence of chronic nausea. Subjects completed validated instruments assessing nausea (Nausea Profile Questionnaire = NPQ), quality of life (Patient-Reported Outcome Measurement Information System), functioning (Functional Disability Inventory), and anxiety (State-Trait Anxiety Inventory for Children). Group comparisons were performed for instruments, multisystem symptoms, school absences, and clinical diagnoses.

KEY RESULTS

A total of 112 subjects were included; 71% reported chronic nausea. Patients with Nausea compared to No Nausea had higher NPQ scores (P ≤ 0.001), worse quality of life (P = 0.004), and greater disability (P = 0.02). State and trait anxiety scores were similar (P = 0.57, P = 0.25). A higher NPQ score correlated with poorer quality of life, more disability, and higher anxiety. Specific comorbidities were more common in Nausea vs No Nausea group: dizziness (81% vs 41%; P ≤ 0.001), concentrating difficulties (68% vs 27%; P ≤ 0.001), chronic fatigue (58% vs 20%; P = 0.01), and sleep disturbances (73% vs 48%; P = 0.02). The Nausea group reported more school absences (P = 0.001) and more commonly met criteria for functional dyspepsia (P = 0.034).

CONCLUSION AND INFERENCES

Nausea co-existing with FAPDs is associated with a higher extra-intestinal symptom burden, worse quality of life, and impaired functioning in children. Assessing and targeting nausea therapeutically is essential to improve outcomes in FAPDs.

Parent psychological flexibility in the context of pediatric pain: Brief assessment and associations with parent behaviour and child functioning

BACKGROUND

The parent's role in the context of pediatric chronic pain is essential. There is growing evidence that parent psychological flexibility positively impacts child functioning. To assess parents' abilities to respond with psychological flexibility to their child's pain, the Parent Psychological Flexibility Questionnaire (PPFQ) was developed. Here, we aim to validate the 10-item version of the questionnaire in an English-speaking population and to evaluate associations with parent behaviour, child pain acceptance and functioning.

METHODS

Five hundred and seventy-eight parent-child dyads presenting at a pediatric pain clinic were included (92% mothers, average child age 15.2 ± 1.6 years). The PPFQ was completed by the parent. Parent and child also completed other standardized questionnaires. In addition to confirmatory factor analysis and assessments of reliability and validity of the PPFQ-10, a mediation analysis was performed to examine the direct and indirect effects of parent psychological flexibility on child functioning.

RESULTS

Confirmatory factor analysis supported the three-factor model with subscales for Values-Based Action, Pain Willingness and Emotional Acceptance, and the PPFQ-10 demonstrated strong psychometric properties. After controlling for child pain, parent psychological flexibility indirectly affected child functioning through its association with both parent behaviour (i.e., protectiveness) and child pain acceptance.

CONCLUSIONS

Our findings provide further support for use of the PPFQ-10 and the importance of assessing and addressing parent psychological flexibility in the context of child chronic pain. Our data show that parent psychological flexibility has an important adaptive role and can impact child functioning through two different routes, both of which can be actively targeted in treatment.

SIGNIFICANCE

Our findings demonstrate that the PPFQ-10 is an efficient measure of parent psychological flexibility, demonstrating strong psychometric properties. Furthermore, our analyses showed that parent psychological flexibility indirectly affects child functioning through associations with both adaptive parent behaviour and child functioning. Taken together, this study furthers the understanding of how parent psychological flexibility operates and affects children with chronic pain, and may inform and optimize treatments aimed at improving functioning by addressing child and parent coping.

Use of the PROMIS-29® to identify subgroups of mothers with chronic pain

OBJECTIVE

Children of mothers with chronic pain are at increased risk for poor health, but few studies have examined what characteristics of maternal chronic pain may be associated with children's risk. This study identified subgroups of mothers based on patterns of pain, physical function, and emotional function on the 29-item Patient-Reported Outcomes Measurement Information System® (PROMIS-29®) and evaluated associations between maternal subgroups and children's pain and emotional functioning.

METHODS

Mothers with chronic pain (n = 334) completed the PROMIS-29® and reported on pain intensity, pain interference, physical functioning, anxiety, depression, fatigue, sleep disturbance, and participation in social activities. Mothers and their school-age children also completed measures of child pain and emotional functioning.

RESULTS

Latent profile analysis of PROMIS® domains indicated a 4-class solution (Group 1: 13.5%, Group 2: 9.9%, Group 3: 43.5%, and Group 4: 32.9%). Group 4 reported the most severe pain, psychological distress, and sleep disturbances and the lowest functioning. Group 1 reported the lowest pain, psychological distress, and sleep disturbances and the highest functioning, while Groups 2 and 3 represented moderate symptoms. Groups significantly differed on maternal reports of children's pain frequency, but not intensity, and children's self-reported somatic symptoms. Further, child depressive symptoms (mother-proxy and self-reported), anxiety (mother-proxy reported), and pain catastrophizing (self-reported) differed by maternal group.

CONCLUSIONS

Patterns of maternal symptoms and functioning were associated with pain frequency and emotional symptoms in children. Further examination of individual differences in mothers with chronic pain that may confer risk for chronic pain and psychological disorders in children is warranted.

Utility of the PROMIS Pediatric Pain Interference Scale in Juvenile Fibromyalgia

OBJECTIVE

The current study tested the utility of the PROMIS Pediatric Pain Interference (PPI) in relation to the widely-used Functional Disability Inventory (FDI) in a small-scale clinical trial.

METHODS

Forty youth with juvenile fibromyalgia (JFM) were randomized to either CBT only or a combined CBT and neuromuscular exercise group (i.e., FIT Teens). Participants completed the PPI and FDI at baseline, post-treatment, and three-month follow-up.

RESULTS

The PPI and FDI were significantly correlated at baseline (r = .51) and post treatment (r = .53), and demonstrated similar improvements (d PPI = .87, d FDI = 1.22, p < .05) at post-treatment following FIT Teens. Following CBT only, neither the PPI nor the FDI improved significantly.

CONCLUSIONS

The PPI may be appropriate for use in non-pharmacologic interventions for pediatric pain.

Longitudinal Evaluation of Pain, Flare-Up, and Emotional Health in Fibrodysplasia Ossificans Progressiva: Analyses of the International FOP Registry

Fibrodysplasia ossificans progressiva (FOP) is an ultra‐rare, inherited, connective tissue disease with ∼800 documented cases worldwide. The principal pathological feature of FOP is the transition of skeletal muscle, tendons, ligaments, and fascia into cartilage and bone. This heterotopic ossification (HO) is often preceded by painful soft tissue swellings or flare‐ups that may last several months. For many individuals, experiencing a flare‐up may represent a worsening of their condition and contribute to feelings of anxiety or suppressed affect, both of which are well‐recognized to exacerbate pain perception. To date, much remains unknown regarding the dynamics of pain and emotional health in FOP during flare‐up and also quiescent, non–flare‐up disease phases. In order to elucidate the occurrence and effect of pain in FOP, this study analyzed Patient‐Reported Outcomes Measurement Information System–based questionnaires completed by 99 patients participating in the international FOP Registry over a 30‐month period. We observed that although moderate to severe pain (≥4, 0 to 10 pain scale) was commonly associated with flare‐ups (56% to 67%), surprisingly, 30% to 55% of patients experienced similar pain levels during non–flare‐up states. In those patients reporting pain levels of ≥4, 45% to 74% of patients report experiencing anxiety, depression, or irritability, with 36% to 48% reporting emotional problems during no to mild pain states. Furthermore, independent of the flare‐up status, the severity of pain in FOP patients was found to be significantly anti‐correlated with emotional health, physical health, and overall quality‐of‐life. These findings strongly suggest the need for an improved understanding of pain and emotional health in FOP during flare‐up and quiescent periods. © 2019 The Authors.

The (Parental) Whole Is Greater Than the Sum of Its Parts: A Multifactorial Model of Parent Factors in Pediatric Chronic Pain

Parents play a critical role in children's experience of, and recovery from, chronic pain. Although several parental factors have been linked to child pain and functioning, these factors are typically examined in isolation or as moderators or mediators. Structural equation modeling affords the opportunity to examine the extent to which parental factors are interrelated, and if there are differential associations among parental factors and child outcomes. Based on extant literature, a unified model of parental factors, including chronic pain status, physical functioning, responses to child pain, and psychological factors, and their effect on child pain and functioning, was conceptualized. This model was evaluated using structural equation modeling based on data from 146 dyads recruited from a multidisciplinary pain clinic. Modifications to model iterations were made based on theoretical and statistical justification. The final model revealed associations among all parental factors, with significant loadings on child pain and functioning. Findings indicated the conceptual model was supported, with the exception of parent responses to child pain. Findings support the inclusion of parent chronic pain status and physical and psychological functioning as part of a comprehensive assessment of youth with chronic pain and may inform new parental intervention targets to improve child outcomes. PERSPECTIVE: A unified structural equation model indicated parents' own chronic pain characteristics and physical and psychological functioning represent important factors associated with child pain and functioning. Current family-based interventions that often primarily focus on parent responses to child pain may need to be adapted to more comprehensively address parental factors.

Quality and Correlates of Peer Relationships in Youths with Chronic Pain

Youths with chronic pain may experience difficulties with peer relationships. We investigated the quality and correlates of peer relationships in a sample of 181 youths with chronic pain. A majority of youths were satisfied with their relationships with peers; however, levels were highly variable. Higher functional impairment and depression levels predicted lower peer relationship quality, controlling for demographic and other pain-related factors. In addition, peer relationship quality and pain severity predicted child depression and anxiety symptoms, whereas peer relationship quality only predicted anger symptoms. Relationship quality moderated the association between pain severity and functional impairment, suggesting that strong relationships with peers may buffer the effects of pain on functioning. Peer relationships seem particularly important for the adjustment and psychological well-being of youths with chronic pain. Particular attention should be given to functionally impaired and depressed children, who may be at higher risk of peer difficulties.

Walk a Mile in the Leadership's Shoes: Why Focus on Quality Improvement?

Quality Improvement (QI) throughout health care in the United States continues to be of growing importance to both patients and providers. Leaders in health care including physicians, nurses, hospital administrators, and payors are all responsible for ensuring the continuation and growth of QI initiatives. This article will discuss various ways that healthcare leaders, with specific regard to orthopedic surgery, have utilized QI measures to provide better, more efficient, care to patients.

Intergenerational examination of pain and posttraumatic stress disorder symptoms among youth with chronic pain and their parents

Introduction

Posttraumatic stress disorder (PTSD) symptoms are prevalent among youth with chronic pain, and associated with poorer pain outcomes and health-related quality of life (HRQoL). Conceptual models suggest that parent factors, including parents' own chronic pain, may be linked to higher co-occurring pain and PTSD symptoms and lower HRQoL in children. However, this has not been empirically examined.

Objectives

The aim of this study was to examine the relationship between parental chronic pain and (1) parent PTSD symptoms, (2) child PTSD symptoms, (3) child pain outcomes, and (4) child HRQoL in a sample of treatment-seeking youth with chronic pain and their parents.

Methods

Youth (n = 173) aged 8 to 18 years and parents (n = 204) recruited from a tertiary-level pediatric chronic pain program completed psychometrically-sound measures of pain and PTSD symptoms. Youth also completed measures of pain interference and HRQoL.

Results

Half of the parents in this sample reported chronic pain. A series of analyses of covariances revealed that parents with vs without chronic pain reported significantly higher PTSD symptoms, and children of parents with vs without chronic pain reported significantly higher PTSD symptoms and pain interference and lower HRQoL.

Conclusion

Findings from this study suggest that having a parent with chronic pain may confer additional risk for children with chronic pain experiencing higher PTSD symptoms, poorer pain outcomes, and lower HRQoL than having a parent without chronic pain. This could be due to genetics or social learning. Future longitudinal research is needed to understand how parental pain influences co-occurring pain and PTSD symptoms, and HRQoL, in children.

The Pivotal Role of Pediatric Psychology in Chronic Pain: Opportunities for Informing and Promoting New Research and Intervention in a Shifting Healthcare Landscape

PURPOSE OF REVIEW

In the context of new efforts to formulate more comprehensive diagnostic and treatment processes for chronic pain conditions, this review aims to provide an overview of some of the most salient developments in the diagnosis and clinical treatment of pediatric chronic pain and to delineate the current and future role of clinical pediatric psychologists in these efforts.

RECENT FINDINGS

The acceptance and promotion of the multidisciplinary approach to pediatric pain management has had an especially significant impact on the field of pediatric psychology. Though chronic pain was historically conceptualized as a biomedical problem, psychology is increasingly viewed as a routine, integral, and component part of treatment. With this evolving biopsychosocial paradigm, pediatric psychology is poised to help shape the development of this field, contributing to emerging conceptual and diagnostic frameworks via consultation, research, clinical care, and education. This review discusses the role of pediatric psychologists as collaborators in emerging diagnostic and assessment frameworks, leaders in pain-related research, drivers of clinical care, and educators for providers, patients, and the lay public. With increased opportunities to enhance the conceptualization and treatment of pediatric pain, pediatric psychologists have an important role to play in reducing the prevalence and persistence of pediatric pain.

Pain-measurement tools in sickle cell disease: where are we now?

Pain is a complex multidimensional experience and the most common morbidity in patients with sickle cell disease (SCD). Tools to assess pain can be of use not only to guide pain treatment but also to provide insight into underlying pain neurobiology. Mechanisms of pain in SCD are multifactorial and are not completely elucidated. Although vaso-occlusion of microcirculation by sickled red cells is believed to be the underlying mechanism of acute vaso-occlusive pain, mechanisms for chronic pain and the transition from acute to chronic pain are under investigation. A number of modalities can be used in clinical practice and/or research to capture various dimensions of pain. Selection of a pain-assessment tool should be directed by the purpose of the assessment. Pain-assessment tools, many of which are currently in the early stages of validation, are discussed here. Development and validation of these multimodal tools is crucial for developing improved understanding of SCD pain and its management.

Multi-Family Pediatric Pain Group Therapy: Capturing Acceptance and Cultivating Change

Behavioral health interventions for pediatric chronic pain include cognitive-behavioral (CBT), acceptance and commitment (ACT), and family-based therapies, though literature regarding multi-family therapy (MFT) is sparse. This investigation examined the utility and outcomes of the Courage to Act with Pain: Teens Identifying Values, Acceptance, and Treatment Effects (CAPTIVATE) program, which included all three modalities (CBT, ACT, MFT) for youth with chronic pain and their parents. Program utility, engagement, and satisfaction were evaluated via quantitative and qualitative feedback. Pain-specific psychological, behavioral, and interpersonal processes were examined along with outcomes related to disability, quality of life, pain interference, fatigue, anxiety, and depressive symptoms. Participants indicated that CAPTIVATE was constructive, engaging, and helpful for social and family systems. Clinical and statistical improvements with large effect sizes were captured for pain catastrophizing, acceptance, and protective parenting but not family functioning. Similar effects were found for functional disability, pain interference, fatigue, anxiety, and depression. Given the importance of targeting multiple systems in the management of pediatric chronic pain, preliminary findings suggest a potential new group-based treatment option for youth and families. Next steps involve evaluating the differential effect of the program over treatment as usual, as well as specific CBT, ACT, and MFT components and processes that may affect outcomes.

Disentangling the Sleep-Pain Relationship in Pediatric Chronic Pain: The Mediating Role of Internalizing Mental Health Symptoms

Background

Pediatric chronic pain often emerges in adolescence and cooccurs with internalizing mental health issues and sleep impairments. Emerging evidence suggests that sleep problems may precede the onset of chronic pain as well as anxiety and depression. Studies conducted in pediatric populations with pain-related chronic illnesses suggest that internalizing mental health symptoms may mediate the sleep-pain relationship; however, this has not been examined in youth with primary pain disorders.

Objective

To examine whether anxiety and depressive symptoms mediated relationships between sleep quality and pain outcomes among youth with chronic pain.

Methods

Participants included 147 youth (66.7% female) aged 8-18 years who were referred to a tertiary-level chronic pain program. At intake, the youth completed psychometrically sound measures of sleep quality, pain intensity, pain interference, and anxiety and depressive symptoms.

Results

As hypothesized, poor sleep quality was associated with increased pain intensity and pain interference, and anxiety and depressive symptoms mediated these sleep-pain relationships.

Discussion

For youth with chronic pain, poor sleep quality may worsen pain through alterations in mood and anxiety; however, prospective research using objective measures is needed. Future research should examine whether targeting sleep and internalizing mental health symptoms in treatments improve pain outcomes in these youth.

Measuring Musculoskeletal Pain in Infants, Children, and Adolescents

Synopsis Accurate, reliable, and timely assessment of pain is critical for effective management of musculoskeletal pain conditions. The assessment of pain in infants, children, and adolescents with and without cognitive impairment can be particularly challenging to clinicians for a number of reasons, including factors related to the consultation (eg, heterogeneous patient population, time constraints), the clinician (eg, awareness/knowledge of available pain scales), standardized assessment scales (eg, availability, psychometric properties, and application of each scale), the patient (eg, developmental stage, ability to communicate), and the context in which the interaction took place (eg, familiarity with the setting and physiological and psychological state). As a result, pain is frequently not assessed or measured during the consultation and, in many instances, underestimated and undertreated in this population. The purpose of this article is to provide clinicians with an overview of scales that may be used to measure pain in infants, children, and adolescents. Specifically, the paper reviews the various approaches to measure pain intensity; identifies factors that can influence the pain experience, expression, and assessment in infants, children, and adolescents; provides age-appropriate suggestions for measuring pain intensity in patients with and without cognitive impairment; and identifies ways to assess the impact of pain using multidimensional pain scales.

Defining pain in newborns: need for a uniform taxonomy?

A framework for defining pain terms such as acute, persistent, prolonged or chronic pain to newborns was derived from the scientific literature on neonatal pain assessments, previous attempts to define chronic pain and the clinical and neurophysiological features of neonatal pain. This novel framework incorporates the temporal features, localising characteristics, and secondary effects of the pain experienced, as well as the behavioural and physiological response patterns of newborns.

CONCLUSION

Although not evidence-based, this framework provides an initial starting point for defining commonly used neonatal pain terms. It will require future revision/refinement based on the accumulating evidence for non-acute pain.

The Feasibility and Validity of PROMIS: A Novel Measure of Quality of Life among Children with Cleft Lip and Palate

BACKGROUND

Health-related quality of life is inconsistently captured among children with cleft lip and palate. The Patient-Reported Outcomes Measurement Information System (PROMIS) captures health-related quality of life, with the added benefit of comparability across clinical conditions. In this study, the authors define the validity and feasibility of PROMIS among children with clefts.

METHODS

Children with cleft lip and palate who were at least 5 years old and able to complete instruments independently were eligible for inclusion (n = 93). Children completed PROMIS anxiety, depression, and peer relationship item banks as short forms or computerized adaptive tests. Participants also completed the Pediatric Quality of Life Inventory. Construct validity was measured by Spearman correlations between PROMIS and the Pediatric Quality of Life Inventory controlling for race, sex, age, and income. Feasibility was measured using instrument completion time, reading level, and floor/ceiling effects.

RESULTS

PROMIS computerized adaptive tests (peer relationship, r = 0.49; depression, r = -0.56; and anxiety, r = -0.36) and short forms (peer relationship, r = 0.65; depression, r = -0.54; and anxiety, r = -0.56) demonstrated moderate correlation with the Pediatric Quality of Life Inventory. Computerized adaptive tests had fewer floor (0 percent versus 0 percent) and ceiling (8.6 to 19.3 percent versus 21.8 to 41.9 percent) effects than short forms, and demonstrated better readability. Computerized adaptive tests required more time than short forms (peer relationship, 0.84 ± 0.67 versus 1.3 ± 0.92; depression, 0.52 ± 0.38 versus 1.1 ± 0.73; and anxiety, 0.53 ± 0.23 versus 1.1 ± 0.62; p = 0.001), as each computerized adaptive test included on average four more questions.

CONCLUSIONS

PROMIS correlates well with the Pediatric Quality of Life Inventory and demonstrates similar accuracy, with better readability and efficiency. Use of PROMIS will improve our ability to compare children with cleft lip and palate to diverse populations and clinical conditions.

Psychometric evaluation of the pediatric and parent-proxy Patient-Reported Outcomes Measurement Information System and the Neurology and Traumatic Brain Injury Quality of Life measurement item banks in pediatric traumatic brain injury

PURPOSE

The primary objective is to provide evidence of convergent and discriminant validity for the pediatric and parent-proxy versions of the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, Depression, Anger, Peer Relations, Mobility, Pain Interference, and Fatigue item banks, the Neurology Quality of Life measurement system (Neuro-QOL) Cognition-General Concerns and Stigma item banks, and the Traumatic Brain Injury Quality of Life (TBI-QOL) Executive Function and Headache item banks in a pediatric traumatic brain injury (TBI) sample.

METHODS

Participants were 134 parent-child (ages 8-18 years) days. Children all sustained TBI and the dyads completed outcome ratings 6 months after injury at one of six medical centers across the United States. Ratings included PROMIS, Neuro-QOL, and TBI-QOL item banks, as well as the Pediatric Quality of Life inventory (PedsQL), the Health Behavior Inventory (HBI), and the Strengths and Difficulties Questionnaire (SDQ) as legacy criterion measures against which these item banks were validated.

RESULTS

The PROMIS, Neuro-QOL, and TBI-QOL item banks demonstrated good convergent validity, as evidenced by moderate to strong correlations with comparable scales on the legacy measures. PROMIS, Neuro-QOL, and TBI-QOL item banks showed weaker correlations with ratings of unrelated constructs on legacy measures, providing evidence of discriminant validity.

CONCLUSION

Our results indicate that the constructs measured by the PROMIS, Neuro-QOL, and TBI-QOL item banks are valid in our pediatric TBI sample and that it is appropriate to use these standardized scores for our primary study analyses.

Pediatric-Collaborative Health Outcomes Information Registry (Peds-CHOIR): a learning health system to guide pediatric pain research and treatment

The pediatric adaptation of the Collaborative Health Outcomes Information Registry (Peds-CHOIR) is a free, open-source, flexible learning health care system (LHS) that meets the call by the Institute of Medicine for the development of national registries to guide research and precision pain medicine. This report is a technical account of the first application of Peds-CHOIR with 3 aims: (1) to describe the design and implementation process of the LHS; (2) to highlight how the clinical system concurrently cultivates a research platform rich in breadth (eg, clinic characteristics) and depth (eg, unique patient- and caregiver-reporting patterns); and (3) to demonstrate the utility of capturing patient-caregiver dyad data in real time, with dynamic outcomes tracking that informs clinical decisions and delivery of treatments. Technical, financial, and systems-based considerations of Peds-CHOIR are discussed. Cross-sectional retrospective data from patients with chronic pain (N = 352; range, 8-17 years; mean, 13.9 years) and their caregivers are reported, including National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) domains (mobility, pain interference, fatigue, peer relations, anxiety, and depression) and the Pain Catastrophizing Scale. Consistent with the literature, analyses of initial visits revealed impairments across physical, psychological, and social domains. Patients and caregivers evidenced agreement in observable variables (mobility); however, caregivers consistently endorsed greater impairment regarding internal experiences (pain interference, fatigue, peer relations, anxiety, and depression) than patients' self-report. A platform like Peds-CHOIR highlights predictors of chronic pain outcomes on a group level and facilitates individually tailored treatment(s). Challenges of implementation and future directions are discussed.

The Effect of Pain Catastrophizing on Outcomes: A Developmental Perspective Across Children, Adolescents, and Young Adults With Chronic Pain

Pain catastrophizing is one of the most powerful predictors of poor outcomes in youth and adults with pain; however, little is known about differential effects of pain catastrophizing on outcomes as a function of age. The current study examined the predictive value of pain catastrophizing on pain interference and pain intensity across children, adolescents, and 2 age groups of young adults with chronic pain. Cross-sectional data are presented from the adult and pediatric Collaborative Health Outcomes Information Registry (CHOIR), including measures of pain catastrophizing, pain intensity, pain interference, and emotional distress from 1,028 individuals with chronic pain. Results revealed that age moderated the relation between pain catastrophizing and pain interference, with the strength of these effects declining with age. The effect of pain catastrophizing on pain interference was strongest in adolescents and relatively weak in all 3 other groups. Emotional distress was the strongest predictor of pain interference for children, whereas pain intensity was the strongest predictor for both adult groups. Pain catastrophizing was found to predict pain intensity and, although age was a significant moderator, statistical findings were weak. Developmental considerations and clinical implications regarding the utility of the construct of pain catastrophizing across age groups are discussed.

PERSPECTIVE

This article explores differences in pain catastrophizing as predictors of pain interference and pain intensity across cohorts of children, adolescents, and 2 age groups of young adults. This work may stimulate further research on chronic pain from a developmental perceptive and inform developmentally tailored treatment interventions that target catastrophizing, emotional distress, and pain intensity.

Posttraumatic stress disorder symptoms in youth with vs without chronic pain

Chronic pain and posttraumatic stress disorder (PTSD) symptoms have been found to co-occur in adults; however, research has not examined this co-occurrence in adolescence, when pediatric chronic pain often first emerges. The aims of this study were to compare the frequency and intensity of PTSD symptoms and stressful life events in cohorts of youth with (n = 95) and without (n = 100) chronic pain and their parents and to determine the association between PTSD symptoms, health-related quality of life, and pain symptoms within the chronic pain sample. All participants completed questionnaire measures through an online survey. Findings revealed that youth with chronic pain and their parents had significantly higher levels of PTSD symptoms as compared with pain-free peers. More youth with chronic pain (32%) and their parents (20%) reported clinically significant elevations in PTSD symptoms than youth without chronic pain (8%) and their parents (1%). Youth with chronic pain also reported a greater number of stressful life events than those without chronic pain, and this was associated with higher PTSD symptoms. Among the chronic pain cohort, higher levels of PTSD symptoms were predictive of worse health-related quality of life and were associated with higher pain intensity, unpleasantness, and interference. Results suggest that elevated PTSD symptoms are common and linked to reduced functioning among youth with chronic pain. Future research is needed to examine PTSD at the diagnostic level and the underlying mechanisms that may explain why this co-occurrence exists.

Using Patient-Reported Outcome Measures to Capture the Patient's Voice in Research and Care of Juvenile Idiopathic Arthritis

Patient-reported outcome (PRO) measures provide a valuable window into how patients with juvenile idiopathic arthritis and their parents perceive their functioning, quality of life, and medication side effects in the context of their disease and treatment. Momentum behind adoption of PRO measures is increasing as these patient-relevant tools capture information pertinent to taking a patient-centered approach to health care and research. This article reviews the clinical and research utility of obtaining PROs across domains applicable to the experience of juvenile idiopathic arthritis and summarizes available self-report and parent-proxy PRO measures. Current challenges and limitations of PRO usage are discussed.
