There is limited information on the health status of urban Australian Aboriginal children and young people attending community-based child health services. Such information is vital to plan appropriate services. The objective of the study is to describe the health status and service use of children and young people presenting to an urban Aboriginal Community Paediatric Service in Sydney, Australia. Cross-sectional analysis of routinely collected data extracted from electronic medical records and the Australian Immunisation Register for urban Aboriginal children and young people aged 0-18 years who visited the service between January 2013 and December 2017. A total of 273 Aboriginal children and young people had 609 occasions of service. Almost all (97.35%) were fully immunised. Forty-six percent of occasions of service noted >3 diagnoses; 55% of the consultations were for mental health and behavioural disorders. The most frequent diagnoses were speech and language delay, attention deficit hyperactivity disorder and school difficulty. Psychosocial concerns were noted in 61.2% of occasions of service, and 19.4% of children had a history of prematurity. Eighty-five percent of consultations had an onward referral to additional services. The most common referrals were for audiology, ear-nose and throat specialists and speech therapy. There were low numbers of referrals to mental health services relative to the high number of mental health diagnoses. It is essential that we address the mental, developmental and psychosocial needs of Aboriginal children and young people who attend urban Community Child Health services. Integrated service models should be developed in partnership with Aboriginal community to do this.
