Development of a core outcome set for clinical trials in childhood asthma: a survey of clinicians, parents, and young people.

ABSTRACT:

Background

In clinical trials in childhood asthma, outcomes reflecting short-term disease activity are frequently measured, whilst functional status, quality of life (QoL), and long-term treatment effects are rarely assessed. There is also non-uniformity across studies in the selection and measurement of outcomes within these domains. The development of a core outcome set has the potential to reduce heterogeneity between trials, lead to research that is more likely to have measured relevant outcomes, and enhance the value of evidence synthesis by reducing the risk of outcome reporting bias and ensuring that all trials contribute usable information.

Methods

Paediatricians and specialist nurses, identified through the British Paediatric Respiratory Society, completed a two-round Delphi survey. Separate cohorts of parents of children younger than 18 years, recruited in clinics, participated in each round. Young people with asthma, aged at least 13 years, participated in the first round. Outcomes were identified separately for preschool and school-aged children.We identified outcomes considered important in routine clinical assessment by clinicians and parents/young people. In round 1, 46 clinicians suggested outcomes they considered important when deciding whether to adjust a child's asthma therapy regime, and 49 parents/young people were asked, using open questions, how they judged whether their child's (for young people, their own) asthma therapy was appropriate. Two researchers independently classified responses into appropriate, corresponding outcomes.In round 2, 43 clinicians and 50 parents scored, from 0-4, the importance of each outcome suggested by at least 10?% of round 1 responders and selected the three most important.

Results

The most important outcomes, when making shared decisions about regular therapies for school-aged and preschool children with asthma, were daytime and nocturnal symptoms, exacerbations, QoL, and mortality. Results from parents and clinicians were generally concordant, but parents placed more emphasis on long-term treatment effects.

Conclusions

We have developed a methodology to identify outcomes of most relevance to clinicians, parents, and young people when evaluating regularly administered therapies for asthma. Daytime and nocturnal symptoms, exacerbations, QoL, and mortality are particularly important outcomes that should be measured and reported in all clinical trials of regular therapies for children with asthma.

Project description:BackgroundBronchiectasis is a chronic respiratory disease characterised by airways widening and recurrent infections, resulting in episodes of chronic cough, sputum expectoration, and dyspnoea. This leads to deterioration in daily function, repeated hospital admissions and poor quality of life. The prevalence and mortality related to bronchiectasis is increasing worldwide with growing economic burden on healthcare systems. Physiotherapy for bronchiectasis aims to decrease accumulation of sputum, dyspnoea, and improve exercise capacity and daily function. A robust evidence base to support physiotherapy in bronchiectasis is currently lacking. This is partly because of inconsistency and poor reporting of outcomes in available studies. A core outcome set is the minimum acceptable group of outcomes that should be used in clinical trials for a specific condition. This decreases research waste by improving consistency and reporting of key outcomes and facilitates the synthesis of study outcomes in systematic reviews and guidelines. The aim of the study is therefore to develop a core outcome set and outcome measurement set for physiotherapy research in adults with bronchiectasis. This will ensure outcomes important to key stakeholders are consistently used and reported in future research.Methods and analysisThis project will use the COMET Initiative and COSMIN guidelines of core outcome set development and will include three phases. In the first phase, a comprehensive list of outcomes will be developed using systematic review of reported outcomes and qualitative interviews with patients and physiotherapists. Then consensus on key outcomes will be established in phase two using a Delphi survey and a consensus meeting. Finally, in phase three, we will identify appropriate instruments to measure the core outcomes by evaluating the psychometric properties of available instruments and a stakeholders' meeting to establish consensus.EthicsThe study was reviewed and has received ethical approval from the health-related Research Ethics Committee- Edge Hill University (ETH2021-0217).RegistrationThis study is registered with the COMET database. https://www.comet-initiative.org/Studies/Details/1931. The full systematic review protocol is registered in PROSPERO under the number CRD42021266247.

Project description:ObjectiveThe objectives of the study were to (1) map questions in epilepsy-specific patient-reported outcome measures (PROMs) of children's health-related quality of life (HRQoL) to a proposed core outcome set (COS) for childhood epilepsy research and (2) gain insight into the acceptability of two leading candidate PROMs.MethodWe identified 11 epilepsy-specific PROMs of children's HRQoL (17 questionnaire versions) in a previous systematic review. Each item from the PROMs was mapped to 38 discrete outcomes across 10 domains of the COS: seizures, sleep, social functioning, mental health, cognition, physical functioning, behavior, adverse events, family life, and global quality of life. We consulted with three children with epilepsy and six parents of children with epilepsy in Patient Public Involvement and Engagement (PPIE) work to gain an understanding of the acceptability of the two leading PROMs from our review of measurement properties: Quality of Life in Childhood Epilepsy (QOLCE-55) and Health-Related Quality of Life Measure for Children with Epilepsy (CHEQOL).ResultsSocial Functioning is covered by all PROMs except DISABKIDS and G-QOLCE and Mental Health is covered by all PROMs except G-QOLCE and Hague Restrictions in Childhood Epilepsy Scale (HARCES). Only two PROMs (Epilepsy and Learning Disability Quality of Life (ELDQOL) and Glasgow Epilepsy Outcome Scale (GEOS-YP)) have items that cover the Seizure domain. The QOLCE-55 includes items that cover the domains of Physical Functioning, Social Functioning, Behavior, Mental Health, and Cognition. The CHEQOL parent and child versions cover the same domains as QOLCE-55 except for Physical Functioning and Behavior, and the child version has one item that covers the discrete outcome of Overall Quality of Life and one item that covers the discrete outcome of Relationship with parents and siblings. The QOLCE-55 parent version was acceptable to the parents we consulted with, and CHEQOL parent and child versions were described as acceptable to our child and parent advisory panel members.SignificanceMapping items from existing epilepsy-specific PROMs for children is an important step in operationalizing our COS for childhood epilepsy research, alongside evaluation of their measurement properties. Two leading PROMS, QOLCE-55 and CHEQOL, cover a wide range of domains from our COS and would likely be used in conjunction with assessment tools selected for specific study objectives. The PPIE work provided practical insights into the administration and acceptability of candidate PROMs in appropriate context. We promote our COS as a framework for selecting outcomes and PROMs for future childhood epilepsy evaluative research.
