Childhood cancer survivorship and health service utilisation in Western Australia: An investigation of trends, risk factors, and financial costs using population-based linked data

The diagnosis and treatment of childhood cancer are associated with organ toxicity and psychological distress. In Australia, the long-term impact of diagnosis- and treatment-related complications on childhood cancer survivors (CCS) remains understudied. This thesis investigates adverse health outcomes among CCS in Western Australia using statewide linked records of hospitalisations and mental health service contacts. Matched-cohort studies revealed that CCS experience a significantly higher burden of physical and psychiatric late effects compared to noncancer controls. These findings underscore the need for continued surveillance to reduce the burden of illness on survivors and the healthcare system.
