Disparities in dental insurance coverage among hospitalised Western Australian children

Abstract

Objectives We sought to understand disparities in dental insurance coverage among hospitalised Western Australian children and associated factors. Methods This study analysed the data obtained for 43,937 child patients under the age of 15 years hospitalised for an oral-health related condition, as determined by principal diagnosis (ICD-10AM). Primary place of residency, age, gender, Indigenous status and socioeconomic status were also analysed. Results Of our sample, 47.3% reported lack of dental insurance coverage. Non-Indigenous children were more likely to have dental insurance than Indigenous children. When insurance status was considered, Indigenous children were less likely to be hospitalised for dental treatment. Rural children were more likely to be uninsured than urban children. Lack of health insurance coverage was strongly associated with children living in very remote areas. These disparities were exacerbated among rural indigenous children. Disparities in dental insurance coverage and dental care are also evident by socioeconomic status. Conclusions Better understanding of disparities in access to care among children, socioeconomic divide in oral health insurance coverage and subsequent development of intervention programmes, will be critical to improving Australian children's oral health.
