The development of the DISCO-RC for measuring children's discomfort during research procedures

A Mixed Method Study in Young Children Participating in Clinical Research During A Kidney Transplantation Trajectory

INTRODUCTION

Regulations designed to protect children participating in clinical research often restrict the availability of research data necessary for the development of age-specific therapies and drug dosing. Few data exist on how children experience participation in clinical research, and studies investigating young children undergoing an intensive medical treatment are lacking.

METHODS

Mixed methods with semi-structured interviews and DISCO-RC questionnaires were used to explore young children's and their parents' experiences in clinical research participation during a kidney transplantation trajectory.

FINDINGS

Nine children and their parents were interviewed. Children's median age at kidney transplantation was 4 years (IQR 4,7); age at interview was 7 years (IQR 6,9). Thematic content analysis of interviews revealed that most children were unaware of having participated in a study. Both children and their parents frequently were unaware whether procedures were standard care or research related. The additional burden attributed to study participation varied from not at all to heavy in combination with intensive medical treatment. Positive experiences included kind healthcare professionals, effective distraction techniques, educational aspects, contributing to science and extra check-ups. Most reported negative experiences were conflicting communication, spending much time in the hospital, missing school and suboptimal planning. Venous puncture was stressful for all children, whereas the discomfort of other procedures varied.

CONCLUSION

Pediatric clinical research design should focus on education and fun during research procedures, smart planning, consistent communication, close collaboration between clinical and research team and age appropriate distraction techniques.

Advancing Wearable Biosensors for Congenital Heart Disease: Patient and Clinician Perspectives: A Science Advisory From the American Heart Association

Wearable biosensors (wearables) enable continual, noninvasive physiologic and behavioral monitoring at home for those with pediatric or congenital heart disease. Wearables allow patients to access their personal data and monitor their health. Despite substantial technologic advances in recent years, issues with hardware design, data analysis, and integration into the clinical workflow prevent wearables from reaching their potential in high-risk congenital heart disease populations. This science advisory reviews the use of wearables in patients with congenital heart disease, how to improve these technologies for clinicians and patients, and ethical and regulatory considerations. Challenges related to the use of wearables are common to every clinical setting, but specific topics for consideration in congenital heart disease are highlighted.

The child's perception on monitoring inflammatory bowel disease activity

To determine the perception of children with inflammatory bowel disease (IBD) regarding monitoring tests, we first compared the reported discomfort and patient perspective during gastro-intestinal (GI)-endoscopy, magnetic resonance entrography (MRE), and ultrasound (US) and, in a second comparison, patient preference on non-invasive tests (venipuncture, sampling stool and US). A cross-sectional study in children 8-18 years undergoing an US, MRE, and GI-endoscopy for diagnosis or follow-up of IBD. After each procedure, the children filled out the Discomfort during research procedures questionnaire (DISCO-RC). Items of the DISCO-RC are as follows: nervousness, annoyance, pain, fright, boredom, and tiredness. Answers range from "not" (= 0 points) to "extremely" (= 4 points) (range total score: 0-24). Differences between the procedures were assessed with Friedman test, with subsequent Wilcoxon signed-rank test. The children were also asked which non-invasive test they preferred not to undergo regularly (venipuncture, stool-sampling, or US). Answers were analyzed with χ²-test. Forty-nine patients (27 (55%) female, median age 15 (range 9-17)) were included. The children reported to be most nervous, frightened, and tired after GI-endoscopy (median: 1, 1, 2 points, respectively), equally annoyed by MRE and GI-endoscopy (median 1 point), and equally bored by MRE and US. GI-endoscopy was ranked as most discomfortable, followed by MRE and US (total DISCO-RC scores: 7 vs. 5 vs. 2, p < 0.001). Most of the children preferred not to sample stool or perform venipuncture regularly (n = 20 (41%, both) (p < 0.001)).Conclusion: Our results suggest that the children with IBD report low discomfort after US, MRE, and GI-endoscopy. US is preferred as a monitoring tool, also among non-invasive monitoring tests. GI-endoscopy was most discomfortable. What is Known: • Children with inflammatory bowel disease need to be monitored frequently for disease activity. • Adult studies - including a systematic review - on acceptability of monitoring tools among IBD patients showed mixed results. What is New: • Children in our study ranked gastro-intestinal endoscopy as most discomfortable, followed by MRE and US. • With regard to non-invasive monitoring, most children preferred not to sample stool or perform venipuncture regularly, and preferred US.

Enhancing validity, reliability and participation in self-reported health outcome measurement for children and young people: a systematic review of recall period, response scale format, and administration modality

Introduction

Self-report is the gold standard for measuring children’s health-related outcomes. Design of such measures is complex and challenging. This review aims to systematically appraise the evidence on recall period, response scale format, mode of administration and approaches needed to enable children and young people < 19 years to participate in valid and reliable self-reporting of their health outcomes.

Method

PsycInfo, Medline, CINAHL and Embase were searched from 1 January 1990 to 15 March 2020, and citation searching undertaken in Scopus. Articles were included if they were primary research or case reports of ≥ 3 participants reporting the following: recall period, response scale selection, administration modality. Quality was assessed using QualSyst, and results synthesised narratively. This review was conducted and reported according to PRISMA guidelines.

Results

81 of 13,215 retrieved articles met the inclusion criteria. Children < 5 years old cannot validly and reliably self-report health outcomes. Face scales demonstrate better psychometric properties than visual analogue or Likert scales. Computerised and paper scales generally show equivalent construct validity. Children prefer computerised measures. Children ≤ 7 years old think dichotomously so need two response options. Those > 8 years old can reliably use a 3-point scale.

Conclusion

The results of this review have both clinical and research implications. They can be used to inform appropriate choice of PROM for use with CYP in the clinical setting. We also give eight recommendations for future development of self-reported outcome measures for children and young people.

The feasibility and acceptability of research magnetic resonance imaging in adolescents with moderate-severe neuropathic pain

Supplemental Digital Content is Available in the Text.

Introduction:

Multimodal characterisation with questionnaires, Quantitative Sensory Testing (QST), and neuroimaging will improve understanding of neuropathic pain (NeuP) in adolescents. Magnetic resonance imaging (MRI) data in adolescents with NeuP are limited, and the perceived practical or ethical burden of scanning may represent a barrier to research.

Objective:

To determine the feasibility of MRI scanning in adolescents with moderate–severe NeuP, with respect to consent rate, postscan acceptability, and data quality.

Methods:

This prospective cohort study evaluating questionnaires and QST recruited adolescents aged 10 to 18 years with clinically diagnosed NeuP from a tertiary clinic. Eligible adolescents aged 11 years and older could additionally agree/decline an MRI scan. After the scan, families rated discomfort, perceived risk, and acceptability of current and future MRI scans (0–10 numerical rating scales). Head motion during scanning was compared with healthy controls to assess data quality.

Results:

Thirty-four families agreed to MRI (72% recruitment), and 21 adolescents with moderate–severe pain (average last week 6.7 ± 1.7; mean ± SD) and with neuropathic QST profiles were scanned. Three adolescents reported positional or noise-related discomfort during scanning. Perceived risk was low, and acceptability of the current scan was high for parents (range [median]: 7 to 10/10 [10]) and adolescents (8–10/10 [10]). Willingness to undergo a future research scan was high for parents (7–10/10 [10]) and adolescents (5–10/10 [10]) and did not differ from future scans for clinical purposes. Mean head motion during resting state functional MRI did not differ from control adolescents.

Conclusion:

Research MRI is feasible and acceptable for many adolescents with moderate–severe NeuP.

Child participation in health care (ChiPaC)-Development and psychometric evaluation of a self-report instrument for children's participation in health care

AIMS AND OBJECTIVES

To develop and evaluate the psychometric properties of a self-report instrument measuring 6- to 12-year-old children's own experiences of participation in health care.

BACKGROUND

Validated measures to evaluate children's participation in health care can play a critical role in strategic work towards supporting children's participation at an individual level and in working towards quality improvements at an organisational level. There are, however, no available instruments to achieve this.

METHODS

An instrument development design was used, together with the TRIPOD checklist. Item construction was based on research about children's perspectives on participation in health care and Shier's model for participation. The face and content validity was evaluated by 14 healthy children, 9 paediatric nurses and 8 children with different diseases. The construct validity, internal consistency and stability reliability were evaluated based on data from 138 children visiting a paediatric clinic.

RESULTS

The testing of the face and content validity resulted in an instrument with child-friendly language, additional instructions and visual attractive presentation. The principle component analysis resulted in the four-factor solution: "To be included," "To trust professionals," "To take control," and "To understand information." Internal consistency and intraclass correlation coefficients were acceptable.

CONCLUSION

We conclude that the child participation in health care (ChiPaC) instrument has adequate reliability and validity when used to evaluate children's participation in health care. The involvement of children in the development of ChiPaC resulted in a brief, colourful and user-friendly instrument for use in paediatric health care.

RELEVANCE TO CLINICAL PRACTICE

This new questionnaire, ChiPaC, is adapted for children between 6-12 years measuring participation in health care from a child perspective. ChiPaC can be used in the practical work of supporting individual children's participation in health care as well as in the strategical work towards quality improvements on an organisational level.

Recessive GM3 synthase deficiency: Natural history, biochemistry, and therapeutic frontier

GM3 synthase, encoded by ST3GAL5, initiates synthesis of all downstream cerebral gangliosides. Here, we present biochemical, functional, and natural history data from 50 individuals homozygous for a pathogenic ST3GAL5 c.862C>T founder allele (median age 8.1, range 0.7-30.5 years). GM3 and its derivatives were undetectable in plasma. Weight and head circumference were normal at birth and mean Apgar scores were 7.7 ± 2.0 (1 min) and 8.9 ± 0.5 (5 min). Somatic growth failure, progressive microcephaly, global developmental delay, visual inattentiveness, and dyskinetic movements developed within a few months of life. Infantile-onset epileptic encephalopathy was characterized by a slow, disorganized, high-voltage background, poor state transitions, absent posterior rhythm, and spike trains from multiple independent cortical foci; >90% of electrographic seizures were clinically silent. Hearing loss affected cochlea and central auditory pathways and 76% of children tested failed the newborn hearing screen. Development stagnated early in life; only 13 (26%) patients sat independently (median age 30 months), three (6%) learned to crawl, and none achieved reciprocal communication. Incessant irritability, often accompanied by insomnia, began during infancy and contributed to high parental stress. Despite catastrophic neurological dysfunction, neuroimaging showed only subtle or no destructive changes into late childhood and hospitalizations were surprisingly rare (0.2 per patient per year). Median survival was 23.5 years. Our observations corroborate findings from transgenic mice which indicate that gangliosides might have a limited role in embryonic neurodevelopment but become vital for postnatal brain growth and function. These results have critical implications for the design and implementation of ganglioside restitution therapies.
