The impact of low socioeconomic status and primary health care access on emergency department presentations in young children in regional Queensland.

The AC/HCC may be an important proxy to identify low SES individuals. These card holders tended to use acute services more frequently than those who did not qualify for an AC/HCC. Furthermore, families that engage with primary care services such as child health also accessed acute care services more frequently. The results indicate accessing primary health-care services does not ameliorate the use of acute care services.
