Systematic Review of Conceptual, Age, Measurement and Valuation Considerations for Generic Multidimensional Childhood Patient-Reported Outcome Measures

BACKGROUND AND AIMS

Patient-reported outcome measures (PROMs) for children (aged ≤ 18 years) present methodological challenges. PROMs can be categorised by their diverse underlying conceptual bases, including functional, disability and health (FDH) status; quality of life (QoL); and health-related quality of life (HRQoL). Some PROMs are designed to be accompanied by preference weights. PROMs should account for childhood developmental differences by incorporating age-appropriate health/QoL domains, guidance on respondent type(s) and design. This systematic review aims to identify generic multidimensional childhood PROMs and synthesise their characteristics by conceptual basis, target age, measurement considerations, and the preference-based value sets that accompany them.

METHODS

The study protocol was registered in the Prospective Register of Systematic Reviews (CRD42021230833), and reporting followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We conducted systematic database searches for generic multidimensional childhood PROMs covering the period 2012-2020, which we combined with published PROMs identified by an earlier systematic review that covered the period 1992-2011. A second systematic database search identified preference-based value sets for generic multidimensional PROMs. The PROMs were categorised by conceptual basis (FDH status, QoL and HRQoL) and by target age (namely infants and pre-schoolers aged < 5 years, pre-adolescents aged 5-11, adolescents aged 12-18 and multi-age group coverage). Descriptive statistics assessed how PROM characteristics (domain coverage, respondent type and design) varied by conceptual basis and age categories. Involvement of children in PROM development and testing was assessed to understand content validity. Characteristics of value sets available for the childhood generic multidimensional PROMs were identified and compared.

RESULTS

We identified 89 PROMs, including 110 versions: 52 FDH, 29 QoL, 12 HRQoL, nine QoL-FDH and eight HRQoL-FDH measures; 20 targeted infants and pre-schoolers, 29 pre-adolescents, 24 adolescents and 37 for multiple age groups. Domain coverage demonstrated development trajectories from observable FDH aspects in infancy through to personal independence and relationships during adolescence. PROMs targeting younger children relied more on informant report, were shorter and had fewer ordinal scale points. One-third of PROMs were developed following qualitative research or surveys with children or parents for concept elicitation. There were 21 preference-based value sets developed by 19 studies of ten generic multidimensional childhood PROMs: seven were based on adolescents' stated preferences, seven were from adults from the perspective of or on behalf of the child, and seven were from adults adopting an adult's perspective. Diverse preference elicitation methods were used to elicit values. Practices with respect to anchoring values on the utility scale also varied considerably. The range and distribution of values reflect these differences, resulting in value sets with notably different properties.

CONCLUSION

Identification and categorisation of generic multidimensional childhood PROMs and value sets by this review can aid the development, selection and interpretation of appropriate measures for clinical and population research and cost-effectiveness-based decision-making.

Health-related quality of life and neurodevelopmental outcomes among children with intestinal failure

Treatment results of pediatric intestinal failure have improved markedly during the last decades. With improved survival the attention is turning to other essential outcomes including quality of life and neurodevelopment. So far, relatively few studies with limited number of patients and variable methodology have addressed these issues. Based on these studies using generic health related quality of life tools, children with intestinal failure demonstrate decreased physical health, while PN-dependence is also associated with compromised emotional functioning. Impairments of social functioning are frequently observed among older children and parents. Few recent studies on neurodevelopment imply significant impairments in motor and mental skills among children with intestinal failure despite small sample sizes and limited follow-up times. Development of a disease-specific survey designed for the pediatric intestinal failure population could better reveal the health issues with greatest impact on quality of life. Robust studies with appropriate methodology on neurodevelopment in pediatric intestinal failure with extended follow-up times are urgently needed. Quality of life and neurodevelopment requires greater attention from medical professionals managing children with intestinal failure.

Sleep duration, quality of life and depression in adolescents: a school-based survey

BACKGROUND

The main objective of this study was to assess the link between sleep duration, quality of life and depression in adolescents. The secondary objective was to study the sleeping behavior of a large sample of adolescents from different socioeconomic backgrounds.

METHODS

Study subjects were high school students studying in or around Paris with a general, vocational or technological training background. A survey was conducted to evaluate the subject's perception of their own sleep, quality of life and depression.

RESULTS

The survey analyzed 855 students between 14 and 19 years of age, with equal numbers of males and females. The average sleep duration was 7 h 14 min ±1 h 20 min and was inversely correlated with age (r=-0.142, P<0.01). Students studying vocational subjects reported significantly more sleep than students studying technological subjects (P=0.02). Univariate analyses revealed a positive relationship between sleep duration and quality of life (r=0.17, P<0.001) and an inverse relationship between sleep duration and depression (r=-0.5, P<0.001). Multivariate analyses identified depression, delayed sleep phase disorder, and medical condition as determinants of sleep duration.

CONCLUSIONS

This investigation of a large student cohort has confirmed that the average sleep duration in adolescents is far below what is recommended. Depression significantly influenced sleep duration. We recommend that a quantitative and qualitative evaluation of sleep should be made during the medical examination of any adolescent.

[Quality of life in HIV-infected children and adolescents under highly active antiretroviral therapy: change over time, effects of age and familial context]

OBJECTIVE

To evaluate Quality of life (QoL) of HIV-infected children under highly active antiretroviral therapies, and its change over 18 months.

MATERIALS AND METHODS

QoL was evaluated by self-administred questionnaires (french versions of AUQUEI, OK-ado, and compilation of both) in 23 young living with HIV/AIDS (6-15 yrs), under antiretroviral multitherapies, and re-evaluated 18 months later in 19 of them.

RESULTS

At baseline, QoL in HIV-infected children-adolescents was relatively good. The answers given to each items and the mean score from infected children were similar to those obtained in uninfected healthy children. Moreover, infected adolescents distinguished definitly from healthy adolescents, describing higher QoL. The mean satisfaction score from the whole group decreased between M0 and M18 (mainly in the youngests), and mainly concerned 3 fields (self-esteem, health and school) while their somatic health remained stable or improved. An effect of the familial context was also observed for these 3 fields.

CONCLUSION

The progressive decline of QoL in HIV-infected children, and the surprising high and steady level of satisfaction over-time provided by the adolescents, underlined the frailty of this population and the need for a psychologic management associated to the medical follow-up. Such a multidisciplinary approach should take into account the preoccupations and difficulties of each age-class, those linked to the diagnosis itself, and to the familial or scolar contexts, in order to preserve QoL of this pediatric population, as far as possible, in a long term.
