A national research survey of childhood autism assessment services in the UK: empirical evidence of diagnostic practice, challenges and improvement opportunities

BACKGROUND

The UK National Health Service (NHS) Long Term Plan aims to reduce waiting times for childhood autism diagnostic assessment and improve parent and child satisfaction. This empirical research investigated current childhood diagnostic practice provision, and changes made by teams to address challenges faced.

METHODS

Data were collected using an online semi-structured research questionnaire. UK childhood autism diagnostic assessment services (for children aged 1-18 years) were invited to participate through multidisciplinary clinical networks, special interest groups and professionals mailing lists. The study was on the National Institute for Health Research Clinical Research Network portfolio.

RESULTS

128 clinicians from diverse NHS services responded including: 10 (8%) integrated services, 46 (36%) Child and Adolescent Mental Health Services (CAMHS) and 72 (56%) paediatric services. A minority of services (23, 17.9%) reported always meeting the National Institute for Health and Care Excellence guidance for assessment. Referrals rose 115% between 2015 and 2019. Clinicians described increased child and family complexity compared with previously; children had more co-occurring physical, mental health and neurodevelopmental conditions and there were more frequent family health problems and safeguarding concerns. Most services (97, 75.8%) reported recent funding stayed constant/decreased. Incomplete multidisciplinary teams (MDTs) were frequently reported; a minority of services reported increased availability of professionals, and some experienced reductions in key professionals. Many teams were unable to undertake assessments or make recommendations for associated neurodevelopmental and co-existing conditions. Teams described improvement strategies implemented (eg, adapting professionals' roles, supporting parents).

CONCLUSIONS

Most UK autism paediatric and CAMHS diagnostic teams experience significant challenges affecting the assessment of children with possible autism, and recommendations regarding treatment/intervention. Where CAMHS or paediatric services work in isolation, there are often competency gaps in MDTs and ability to deliver full neurodevelopmental and mental health assessments. Teams identified service improvement strategies; however, investment in MDT expertise is required to enable services to implement changes to meet the needs of children and families.

Sex differences in childhood sleep and health implications

CONTEXT

Sleep is critical for optimal childhood metabolic health and neurodevelopment. However, there is limited knowledge regarding childhood sex differences in sleep, including children with neurodevelopmental disorders, and the impact of such differences on metabolic health.

OBJECTIVE

To evaluate if sex differences in childhood sleep exist and if sleep associates with metabolic health outcomes equally by sex. Using autism spectrum disorder (ASD) as a case study, we also examine sleep sex differences in children with a neurodevelopmental disorder.

METHODS

A narrative review explored the literature focussing on sex differences in childhood sleep.

RESULTS

Sex differences in sleep were not detected among pre-adolescents. However, female adolescents were more likely to report impaired sleep than males. Childhood obesity is more common in males. Shorter sleep duration may be associated with obesity in male pre-adolescents/adolescents; although findings are mixed. ASD is male-predominant; yet, there was an indication that pre-adolescent female children with ASD had more impaired sleep.

CONCLUSION

Sex differences in sleep appear to emerge in adolescence with more impaired sleep in females. This trend was also observed among pre-adolescent female children with ASD. Further research is needed on sex differences in childhood sleep and metabolic health and the underlying mechanisms driving these differences.

Sufficient sleep duration in autistic children and the role of physical activity

LAY ABSTRACT

Higher levels of physical activity may be associated with improved sleep in children, but this relationship is still being determined, especially in autistic children. In this study, we used existing data from the 2018 National Survey of Children's Health. Caregivers of children 6-17 years old, including caregivers of autistic children, completed a questionnaire that included questions about physical activity (days active in the past week) and sleep duration. We then determined if children were obtaining the recommended hours of sleep for their age (i.e. sufficient sleep). We found that higher physical activity levels were associated with sufficient sleep duration, but this finding was weaker in autistic children. In particular, this association was not observed in autistic children with more severe autism spectrum disorder, female autistic children, and autistic children 6-12 years old. In conclusion, physical activity is a promising approach to help children obtain sufficient sleep duration. However, more personalized approaches to improving sleep may be needed for certain groups of autistic children.

A High Prevalence of Autism Spectrum Disorder in Preschool Children in an Immigrant, Multiethnic Population in Sweden: Challenges for Health Care

This study examines the prevalence of autism spectrum disorder (ASD) in preschool children in an immigrant population. Possible risk factors for ASD and individual needs for the children and their families are described, as well as implications for health care. The estimated minimum prevalence for ASD in the area was 3.66% for children aged 2–5 years. Multiple risk factors and extensive individual needs for the children and their families were observed. The high prevalence of ASD and the plethora of needs in immigrant communities pose challenges for health care. A coordinated health care system is necessary to meet the many and individual needs.

Polymorbidity of developmental disabilities: Additive effects on child psychosocial functioning and parental distress

BACKGROUND

While parents of children with developmental disabilities show greater parenting burden and distress compared with their counterparts, little is known about to what extent developmental polymorbidity in children escalates and magnifies the risk of parental distress.

AIMS

This study investigated the co-occurrence of developmental disabilities among a sample of elementary school children and examined its additive effects on child psychosocial functioning and parental distress.

METHODS AND PROCEDURES

A cross-sectional survey among 710 parents of elementary school children in Hong Kong included measures of child psychosocial functioning and parental stress. Structural equation modeling was used to test a hypothesized model in which child psychosocial functioning mediates the effect of developmental polymorbidity on parental distress.

OUTCOMES AND RESULTS

About one-fourth of the participants reported their children having two or more developmental disabilities. The number of developmental disabilities was positively related to the severity of emotional and behavioral problems in children, which in turn explained general and parenting distress in parents.

CONCLUSIONS AND IMPLICATIONS

Given the heightened vulnerability to distress among parents of children with multiple developmental disabilities, psychological care should particularly target this population. Early identification and intervention strategies are also needed to detect children with multiple co-occurring developmental disabilities, which could potentially alleviate their emotional and behavioral problems and lessen the parenting burden.
