Quantifying Cancer Healthcare Costs for Adolescents and Young Adults in Queensland, Australia.

BACKGROUND: Adolescents and young adults (AYAs) with cancer have unique needs as they transition from childhood to adulthood. This study explored the patterns of health service use and the related costs incurred by the health care system and out-of-pocket (OOP) costs for AYAs diagnosed with cancer in Queensland, Australia. METHODS: A linked administrative dataset (CancerCostMod) containing all AYA cancer survivors (n = 871; aged 15-24) diagnosed between July 2011 and June 2015 from the Queensland Cancer Registry (QCR) linked these records to Queensland Health Admitted Patient Data Collection (QHAPDC), Emergency Department Information System (EDIS), Medicare Benefits Schedule (MBS), and Pharmaceutical Benefits Scheme (PBS) records from July 2011 to June 2018. We quantified total and average health service use, associated costs, OOP costs, and costs variations across sociodemographic characteristics. RESULTS: The public hospital costs incurred for AYAs diagnosed with cancer were higher (AUD 33.7 M) compared to private hospitals (AUD 12.6 M). The median cost per person for public admissions (AUD 9759, IQR = AUD 0-37,245). AYAs claimed 215,900 MBS items and 58,321 PBS items over a five-year period. First Nations Australians and individuals living in regional and mostly disadvantaged areas had higher public hospital admissions, associated costs, and ED admissions compared to their counterparts. CONCLUSIONS: This study revealed significant variations in healthcare costs for AYAs diagnosed with cancer. Public hospital costs were higher, with notable differences observed across sociodemographic characteristics.
