Development and preliminary testing of the Brief Developmental Assessment: an early recognition tool for children with heart disease

Introduction: Neurodevelopmental abnormalities are common in children with CHD and are the highestpriority concerns for parents and professionals following cardiac surgery in childhood. There is no additional routine monitoring of development for children with CHD in the United Kingdom; hence, neurodevelopmental concerns may be detected late, precluding early referral and intervention. Methods: An early recognition tool – the “Brief Developmental Assessment” – was developed using quality improvement methodology involving several iterations and rounds of pilot testing. Our requirements were for a tool covering important developmental domains and practicable for use within inpatient and outpatient settings by paediatric cardiac health professionals who are nondevelopmental specialists, without specialised equipment and which involved direct observation, as well as parental report. Results: Items were included in the tool based on existing developmental measures, covering the domains of gross and fine motor skills, daily living skills, communication, socialisation, and general understanding. Items were developed for five age bands – 0–16 weeks, 17–34 weeks, 35–60 weeks, 15 months–2.9 years, and 3–4.9 years – and the final versions included a traffic light scoring system for identifying children with possible delay in any or all domains. Preliminary testing indicated excellent inter-rater reliability, an ability to detect children with a diagnosis known to be associated with developmental delay, and largely acceptable internal reliability. Conclusion: We report the evolution and preliminary testing of an early recognition tool for assessing the development of children with heart disease; this was encouraging and sufficiently good to support further validation in a larger study.
