Validity and Responsiveness of the Patient-reported Outcomes Measurement Information System in Children With Ulcerative Colitis

Responsiveness and clinical utility of PROMIS instruments in pediatric Crohn's disease: insights from a longitudinal study

Background

Inflammatory bowel disease (IBD) may adversely affect physical, psychological, and social well-being. Integrating patient-reported outcomes (PROs) into clinical practice is crucial for comprehensive disease management.

Objective

To evaluate the responsiveness and clinical utility of Patient-Reported Outcomes Measurement Information System (PROMIS) instruments, compared with standard clinical assessment tools in pediatric CD patients.

Methods

A longitudinal, prospective study with 31 pediatric Crohn's disease (CD) patients aged 8-17 years recruited from a Pediatric Gastroenterology Unit. Data were collected at baseline and every 6 months over 18 months. PROMIS pediatric measures assessed PROs. Disease activity was evaluated using the pediatric Crohn's disease activity index (PCDAI) and clinical markers. IMPACT-III was also applied. Linear mixed-effects models (LMMs) and bivariate analyses were used to assess changes over time.

Results

PROMIS Global Health scores showed significant improvement over time, indicating enhanced overall health perceptions among patients. Notable reductions were observed in PROMIS Pain Interference and Fatigue scores, indicating better physical health. PROMIS depression scores generally decreased, suggesting improved mental health. PCDAI scores, hemoglobin, and platelet count significantly changed and correlated with PROMIS measures. Globally, the study demonstrated significant and clinically relevant changes in multiple PROMIS measures, confirming their responsiveness to changes in disease activity.

Conclusion

PROMIS instruments are clinically useful in managing pediatric CD, providing valuable insights into global health and quality of life. Integrating PROMIS measures into routine clinical practice may enhance disease management and treatment strategies for pediatric IBD patients.

Operating Properties of Disease Activity Indices in Pediatric Inflammatory Bowel Disease: A Systematic Review

BACKGROUND

Accurate, reliable, and responsive disease activity indices are important to streamline drug approval and treatment modalities for pediatric inflammatory bowel disease (pIBD). We aimed to identify all scoring indices used in pIBD randomized controlled trials (RCTs) and to evaluate their operating properties.

METHODS

MEDLINE, EMBASE, and CENTRAL were searched on December 6, 2022, to identify studies evaluating clinical, endoscopic, imaging, or patient-reported outcome measures (PROMs) in pIBD including Crohn's disease (CD) and ulcerative colitis (UC). Validity, reliability, responsiveness, and feasibility were summarized.

RESULTS

Seventy RCTs evaluating pIBD indices were identified. Forty-one studies reported on the operating properties of 14 eligible indices (n = 9 CD, n = 5 UC). The Pediatric Crohn's Disease Activity Index (PCDAI) varied widely in terms of validity and reliability and was less feasible overall. In contrast, the Mucosal Inflammation Noninvasive Index, which includes fecal calprotectin, had better operating properties than the PCDAI. The Simplified Endoscopic Mucosal Assessment of Crohn's Disease appears more feasible and had similar operating properties than the longer Simple Endoscopic Score for Crohn's Disease. The Pediatric Ulcerative Colitis Activity Index was feasible, valid, and reliable, but responsiveness needs to be evaluated further. The Endoscopic Mayo score and the Ulcerative Colitis Endoscopic Index of Severity were reliable, but validity and responsiveness need to be evaluated further. Imaging and PROMs/quality of life indices need further evaluation.

CONCLUSIONS

The operating properties of pIBD clinical trial end points varied widely. These results highlight the need for further validation and development of novel indices.

Clinical usefulness of patient-reported-outcome-measurement information system in Pediatric Crohn's Disease: a cross-sectional study

OBJECTIVES

This study evaluated the clinical utility of the Patient-Reported Outcomes Measurement Information System (PROMIS®) by comparing it with objective clinical data and validated health-related quality of life (HRQOL) measures in pediatric Crohn's disease (CD) patients.

STUDY DESIGN

Cross-sectional study. Pediatric CD patients (aged 8-17 years) were enrolled prospectively over eight months from an outpatient pediatric gastroenterology center. We assessed the associations between PROMIS® Pediatric short-form measures, demographic and disease-related data, global clinical assessments, and HRQOL measures. A subanalysis according to the PCDAI (remission versus active disease) was also conducted.

RESULTS

Thirty-one patients (mean age: 15.3; 58% female) with a mean disease duration of 2.7 years were included; 80.6% were in remission or had mild disease. The PROMIS® score was significantly correlated with several factors: age was negatively correlated with the PROMIS® Global Health Scale (r=-0.399; p = 0.026) and Life Satisfaction (r=-0.359; p = 0.047); sex was associated with the PROMIS® Cognitive Function Scale (t = 2.20; p = 0.038), favoring males; and school level was inversely related to the PROMIS® Peer Relationships (F = 3.90; p = 0.003). Clinical assessments also revealed significant correlations between hemoglobin and PROMIS® Global Health (r = 0.356; p = 0.049) and pain interference (r=-0.360; p = 0.046) and between ferritin and PROMIS® Meaning and Purpose (r = 0.435; p = 0.016) and cognitive function (r = 0.450; p = 0.011). Disease activity assessments correlated significantly with multiple PROMIS® measures, with better scores in patients in remission. Treatment changes, particularly corticosteroid treatment, negatively impacted the PROMIS® Anxiety and Life Satisfaction scores. IMPACT-III scores correlated positively with PROMIS® Global Health, Meaning and Purpose, Life Satisfaction, and peer relationships scores and negatively with Depression, Anxiety, Pain interference, and Fatigue scores. Group analysis indicated better PROMIS® scores and HRQOL scores in remission than in active disease remission.

CONCLUSION

Consistent with recent evidence, PROMIS® scores reliably reflect disease activity and HRQOL. The meaningful associations with clinical assessment and treatment efficacy reinforce the clinical relevance and utility of PROs in the patient-centered management of pediatric IBD and highlight the importance of self-reports as a gold standard tool for assessing health status.

Patient-Reported Outcomes Measurement Information System as a Clinical Tool for Capturing the Patient Perspective in Pediatric Inflammatory Bowel Disease: A Narrative Review

Inflammatory bowel disease (IBD) is an immune-mediated chronic disease with a significant impact on quality of life. In pediatric patients, diagnosing and managing IBD is particularly challenging, and IBD often presents as a more severe and progressive disease. Patient-reported outcomes (PROs) are measures of treatment and disease management outcomes reported by patients and/or caregivers. These measures evaluate several aspects of disease management from the patient/caregiver perspective, emphasizing the patient's real-life experience with the disease and its treatment. PROs represent a model of patient-centered care, facilitating better-informed healthcare decisions. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to promote the use of PROs among patients with chronic conditions. Its primary objective is to provide PROs for research and clinical practice throughout the lifespan. The PROMIS is a non-disease-specific instrument for both adults and pediatric patients assessing domains of physical, psychological, and social health, as well as quality of life (QOL). These instruments are designed to be applicable to a wide range of chronic diseases. Despite the initial expectation concerning PROs in assessing pediatric IBD outcomes, objective data in this area have only recently begun to emerge. This narrative review, based on a selection of reliable articles recognized by PubMed and Cochrane Library, aimed to identify and summarize previously published evidence of the usefulness of PROs, particularly the PROMIS, in IBD patients and in the pediatric population. We present an updated perspective, including identification of their general applications and most relevant previous studies, in the mentioned areas and identify knowledge gaps.

Self-Compassion in Adolescents and Young Adults With Inflammatory Bowel Disease: Relationship of Self-Compassion to Psychosocial and Physical Outcomes

BACKGROUND

Adolescents and young adults (AYAs) diagnosed with inflammatory bowel disease (IBD) are at an increased risk for poor physical and mental health due to the complexity of pediatric onset IBD and the unique developmental challenges of this period of life. Self-compassion is increasingly recognized as having an important role in explaining health outcomes and well-being across a range of populations. This study examines the relationship between self-compassion and psychosocial and physical health outcomes in AYAs with IBD.

METHODS

In this cross-sectional study, AYAs with IBD aged 15 to 25 years completed an online survey between February 2020 and October 2021. Questionnaires included the Self-Compassion Scale-Short Form, Patient-Reported Outcomes Measurement Information System (PROMIS) measures for psychosocial, physical and global health outcomes, and IBD disease activity indices.

RESULTS

AYAs with higher levels of self-compassion were found to have better psychosocial (ie, anxiety, depressive symptoms, psychological stress, physical stress, peer relationships), physical (ie, fatigue), and global health outcomes. Self-compassion was a significant independent predictor of anxiety (β = -5.80, P = < .001), depressive symptoms (β = -7.09, P = < .001), psychological stress (β = -4.66, P = < .001), physical stress (β = -3.19, P = < .001), peer relationships (β = 3.39, P = .003), fatigue (β = -2.05, P = .019), and improved global health (β = 5.15, P = < .001).

CONCLUSIONS

This study offers preliminary support for the importance of self-compassion in AYAs with IBD and demonstrates the need for further research in this area.

Health-Related Quality of Life and Perceived Stigma in Eosinophilic Esophagitis: A Real-World, US, Web-Based Survey

Background and Aims

Eosinophilic esophagitis (EoE) is associated with impaired health-related quality of life (HRQoL) and stigma perceptions. Therefore, we examined the real-world impact of EoE on the daily life and ability to function in adolescents (caregiver-reported) and adults with EoE in the United States of America in a noninterventional, cross-sectional, web-based survey.

Methods

HRQoL was assessed using the Short Form Health Survey (domains: vitality and social functioning) and the European Health Interview Survey (domain: sleep). Scores for the survey responses were on a scale of 0 to 100; higher scores indicated better performance in the HRQoL domain. Anxiety and depression were assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) short forms. Higher PROMIS scores indicated higher levels of anxiety and depression; a mean score of 50.0 was representative of the general population (individuals without EoE). The sources and impact of EoE-associated perceived stigma were also examined.

Results

Overall, 211 caregivers and 184 adults completed the survey. HRQoL scores were slightly higher for adolescents than adults with EoE (adolescent and adult scores, respectively: vitality, 50.3 and 36.1; social functioning, 64.0 and 62.4; and sleep, 55.7 and 52.0). Anxiety scores (adolescent and adult scores, respectively: 54.8 and 59.7) and depression scores (54.5 and 56.3) were higher in those with EoE than in the general population. Most participants reported experiencing perceived stigma, which was most commonly from family, friends, classmates, or health-care professionals.

Conclusion

Patients with EoE had poor HRQoL, which was demonstrated by the high EoE-associated emotional and psychological burdens and perceived stigma they experience.

Recommendations for Patient-Reported Outcomes Measurement Information System pediatric measures in youth with chronic pain: a COnsensus-based Standards for the selection of health Measurement INstruments systematic review of measurement properties

ABSTRACT

The Patient-Reported Outcome Measurement Information System (PROMIS) pediatric measures assess physical, emotional, and social health among children and adolescents. However, their measurement properties have not been systematically examined in youth with chronic pain. A systematic review applying the COnsensus based Standards for the selection of health Measurement INstruments (COSMIN) methodology was conducted to evaluate self-reported PROMIS pediatric measures in youth with chronic pain, assessing 8 measurement properties across all versions (item bank, short form, and computer adaptive testing) from 63 studies covering 25 measures. Moderate or high-quality evidence was most available for content validity, structural validity, internal consistency (measurement precision), and construct validity. Four short-form PROMIS pediatric measures-mobility, anxiety, depressive symptoms, and physical stress experiences-achieved recommendation for the use in chronic pain clinical trials; 7 approached recommendation and 14, including the commonly used PROMIS Pediatric Pain Interference Scale, would be recommended with further evidence. Recommendations were also provided for the use of each measure in observational studies. Overall, based on the existing evidence, a total of 11 self-reported PROMIS pediatric short-form measures, including pain intensity, pain behavior, mobility, sleep disturbance, sleep-related impairment, anxiety, depressive symptoms, psychological stress experiences, physical stress experiences, family relationships, and positive effect, are recommended or approaching recommendation for use in youth ages 8 to 19 years with chronic pain. Research is needed to further establish test-retest reliability, measurement errors, cross-cultural validity, and responsiveness. Future work should expand the evaluation of PROMIS pediatric measures in subpopulations of youth with chronic pain, particularly young children and those with neurodevelopmental disabilities.

Computerized-adaptive testing versus short forms for pediatric inflammatory bowel disease patient-reported outcome assessment

Introduction

Computerized-adaptive testing (CAT) may increase reliability or reduce respondent burden for assessing patient-reported outcomes compared with static short forms (SFs). We compared CAT versus SF administration of the Patient-Reported Outcomes Measurement Information System® (PROMIS®) Pediatric measures in pediatric inflammatory bowel disease (IBD).

Methods

Participants completed 4-item CAT, 5- or 6-item CAT, and 4-item SF versions of the PROMIS Pediatric measures. We compared average T-scores, intra-class correlations (ICCs), floor and ceiling effects, and standard error of measurement (SEM) across forms, along with mean effect sizes between active versus quiescent IBD disease activity groups.

Results

Average PROMIS T-scores across forms were <3 points (minimally important difference) of each other. All forms correlated highly with each other (ICCs ≥0.90) and had similar ceiling effects, but the CAT-5/6 had lower floor effects. The CAT-5/6 had lower SEM than the CAT-4 and SF-4, and the CAT-4 had a lower SEM than the SF-4. Mean effect sizes were similar across forms when contrasting disease activity groups.

Conclusions

The CAT and SF forms produced similar score results, but the CAT had better precision and lower floor effects. Researchers should consider PROMIS pediatric CAT if they anticipate that their sample will skew toward symptom extremes.

Equivalence of Paper and Electronic-Based Patient Reported Outcome Measures for Children: A Systematic Review

Patient-reported outcome measures (PROMs) exist for a variety of chronic gastrointestinal disorders in children. The availability of electronic (e-)formats of PROMs enhance the accessibility of these tools. The International Society for Pharmacoeconomic and Outcomes Research (ISPOR) defines measurement equivalence (ME) as "comparability of the psychometric properties of data" obtained from the administration of original and adapted versions of PROMs. Consideration of proxy PROM versions is unique to pediatrics and must be included in ME evaluations. We conducted a systematic review (SR) of the literature evaluating ME of e-versions adapted from pediatric paper-based PROMs. A literature search was conducted through Medline, Embase, APA PsychInfo, and the Cochrane Library. Titles, abstracts, and manuscripts were reviewed by 2 independent reviewers. The search yielded 19 studies meeting pre-defined criteria. Just over half (52.6%) of 19 PROMs were disease-specific ones. ME between paper- and e-PROM versions was reported as present in all 19 studies evaluating 5653 participants under the age of 18 years. However, only 6 (31.6%) studies evaluated ME in proxy reported e-versions. Despite the use of PROMs for children with a variety of chronic gastrointestinal disorders, only 1 study evaluated a PROM in this population (IMPACT III for inflammatory bowel disease). Findings from this SR highlight strategic opportunities for the pediatric gastroenterologist to broaden the clinical and research armamentarium to include e-PROMs.

Health-Related Quality of Life in Pediatric Inflammatory Bowel Disease During COVID-19 Pandemic: A Prospective Study

OBJECTIVES

The aims of our study were to evaluate health-related quality of life (HRQoL) in children affected by inflammatory bowel disease (IBD) during the first wave of Coronavirus disease 2019 (COVID-19) pandemic and after 12 months.

METHODS

This was a single-center, prospective, observational study conducted between April 2020 and April 2021. Children from 10 to 18 years with a confirmed diagnosis of IBD were enrolled during the first COVID-19-related national quarantine. The following information was collected at the baseline and after 12 months: IBD subtype, location and phenotype, disease activity, current and previous therapies. Patients were asked to complete the PROMIS Anxiety and IMPACT III questionnaires.

RESULTS

One hundred and eighteen patients were enrolled, of whom 54 (46%) were affected by Crohn disease (CD) and 64 (54%) with ulcerative colitis (UC; median age: 15.5 years, range 10.3-18; M/F: 68/50). Median HRQoL was significantly decreased after 12 months compared with the beginning of COVID-19-related quarantine (T1: 76.7 vs T2: 72.8; P < 0.001). At 12 months, a higher number of children were reported to be in active disease when compared with the enrollment [T2: 22/108 (20.4%) vs T1: 12/118 (10%); P = 0.02]. Multivariate analysis showed a significant influence on HRQoL of quarantine period ( P < 0.001), female sex ( P = 0.016), biologic therapy ( P = 0.011), and active disease ( P < 0.001).

CONCLUSIONS

A deterioration of HRQoL after 12 months from COVID-19-related quarantine was observed. Additionally, the higher number of children with active disease at 12 months compared with enrollment may suggest detrimental consequences of the reduced disease control, contributing to decreased HRQoL.

Use of Patient-Reported Outcomes Measurement Information System Pediatric Measures as Clinical Trial Endpoints: Experience from a Multicenter Pragmatic Trial in Children with Crohn's Disease

OBJECTIVES

To evaluate whether Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric patient-reported outcome (PRO) measures can serve as valid endpoints in a clinical trial of a chronic pediatric illness.

STUDY DESIGN

We evaluated the responsiveness of PROMIS pediatric measures collected through the Clinical Outcomes of Methotrexate Binary Therapy in Practice (COMBINE) trial, a multicenter, randomized, double-blind, placebo-controlled, pragmatic clinical trial in pediatric patients with Crohn's disease (CD). We examined the relationships between changes in PROMIS pediatric measures and changes in disease activity by evaluating PRO score changes among patients who did and patients who did not experience improvement in disease activity.

RESULTS

Participants included 266 children and adolescents with CD from a total of 35 institutions. Over the course of follow-up, participants showed improvement in most PRO domains, with the largest effect sizes observed for the clinically improved group. Patients who maintained steroid-free remission showed significantly lower PRO scores for the Pain Interference, Fatigue, and inflammatory bowel disease (IBD) Symptoms domains and higher scores for the Positive Affect domain.

CONCLUSIONS

This study demonstrates the responsiveness of the PROMIS pediatric measures of Fatigue and Pain Interference as study endpoints in a large, multicenter pragmatic trial in pediatric CD, extending a growing body of research supporting the use of PROMIS pediatric measures as reliable PRO endpoints for clinical trials.

Anxiety and Depressive Symptoms Are Not Associated With Future Pediatric Crohn's Disease Activity

BACKGROUND

Studies of adults with Crohn's disease (CD) suggest that poor mental health precedes worsening disease activity. We evaluated whether depression and/or anxiety forecast worsening pediatric CD disease activity.

METHODS

Through the Inflammatory Bowel Disease Partners Kids & Teens internet-based cohort, children with CD age 9 to 17 completed Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric measures and the short Crohn's disease activity index (sCDAI). Using general linear models, we examined how baseline PROMIS Pediatric anxiety and depressive symptom scores independently associate with subsequent sCDAI scores (average survey interval 6.4 months). Models included baseline PROMIS Pediatric anxiety and depressive symptoms scores, baseline sCDAI, sex, age, parental education, race/ethnicity, and prior IBD-related surgery. We performed a post hoc subanalysis of children in baseline remission (sCDAI <150) with otherwise identical models.

RESULTS

We analyzed 159 children with CD (mean age 14 years, 45% female, 84% in baseline remission). We found no association between baseline PROMIS Pediatric anxiety score and subsequent sCDAI (change in sCDAI for 3-point change in PROMIS Pediatric -0.89; 95% CI -4.81 to 3.03). Baseline PROMIS Pediatric depressive symptoms score was not associated with future sCDAI (change in sCDAI for 3-point change in PROMIS Pediatric <0.01; 95% CI -4.54 to 4.53). In a subanalysis of patients in remission at baseline, the lack of association remained.

CONCLUSION

We found that neither anxiety nor depressive symptoms associate with subsequent disease activity in pediatric CD. These findings contrast with adult IBD studies, thus underschoring the unique pathophysiology, natural history, and outcomes of pediatric CD.
