Do autistic patients change healthcare services utilisation through the transition age? An Italian longitudinal retrospective study.

ABSTRACT:

Objectives

This paper aims to provide an estimate of the prevalence rate of autism spectrum disorder (ASD) in 8-year-olds in 2017 based on administrative databases and to investigate the change in healthcare service use during the healthcare transition age of 18.

Design

This research is based on a longitudinal retrospective cohort study.

Setting

The data is drawn from the Italian Administrative Healthcare Database (2010-2017).

Participants

We identified 5607 ASD patients; 331 ASD patients from 2012 to 2015 in the calendar year of their 18th birthday were selected and their health service utilisation during a 5-year period-ranging from 2 years preceding and succeeding their 18th year-were investigated.

Interventions

None.

Primary and secondary outcome measures

Prevalence, incidence and proportion of ASD patients receiving specific healthcare services were included in the outcome measures.

Results

Prevalence of ASD at age 8 was 5.4/1000. Global access to health and social services was lower both before and after age 18 (46.5% at 16; 68.0% at 18; 54.1% at 20). The percentage of patients receiving a neuropsychiatric consultation decreased after age 18 (30.8% at 18; 5.4% at 20). Community mental health services (CMHS) utilisation rate increased above 18 years of age. Regarding psychiatric visits, for both outpatient and CMHS, an increase was observed from 17.8% at age 18 to 25.4% at age 20. The utilisation of rehabilitation services decreased with age, dropping from 17.8% at age 16 to 1.8% at age 20. Psychiatric outpatient services remained stable across ages at about 14%.

Conclusion

Our findings suggest that ASD patients changed clinical reference services with age from neuropsychiatric and rehabilitative services towards psychiatric and community-based services as they transitioned from paediatric to adult healthcare services.
