'Caregivers' awareness matters': Call for a child-centred approach to early detection of autism spectrum disorder through well-child visits in Japan.

BACKGROUND

Early detection of autism spectrum disorder (ASD) is essential to provide children with timely treatment and support. Evidence-based screening measures make it possible to identify children with suspected ASD at an early stage. Although Japan has a universal healthcare system that covers well-child visits, detection rates of developmental disorders, including ASD, at 18 months vary widely between municipalities (0.2%-48.0%). The reasons for this high level of variation are poorly understood. The present study aims to describe the barriers and facilitators of incorporating ASD identification during well-child visits in Japan.

METHODS

This is a qualitative study that conducts semi-structured in-depth interviews in two municipalities of Yamanashi Prefecture. We recruited all public health nurses (n = 17) and paediatricians (n = 11) involved in the well-child visit in each municipality and caregivers of children who also participated in the visits during the study period (n = 21).

RESULTS

We identified four themes characterizing the process of ASD identification in the target municipalities: (1) Identification of children with ASD is driven by caregivers' sense of concern, acceptance and awareness. (2) Multidisciplinary cooperation and shared decision-making is limited. (3) Skills and training for developmental disabilities screening are underdeveloped. (4) Caregivers' expectations shape the interaction in important ways.

CONCLUSIONS

Non-standardization of screening methods, limited knowledge and skills on screening and child development among healthcare providers and poor coordination among healthcare providers and caregivers are the main barriers to effective early detection of ASD through well-child visits. The findings suggest the importance of promoting a child-centred care approach through the application of evidence-based screening measures and effective information sharing.
