The Cancer Health Services Research unit drives a strong data-driven research program that is focussed on improving the delivery of cancer services. The CHSR unit has a common research interest in data-science and data-linkage of different large medical and administrative registries to be able to monitor the care provided to cancer patients across the care continuum. Clinical outcomes and cost analyses using linked data-sets inform the value of our services to patients and help rationalise decisions about improving our services mainly in hospital settings.
