We specialise in partnering with health system collaborators to undertake pragmatic, real-world evaluations of the cost, impacts and long-term sustainability of new and innovative service models. Current evaluations include assessing the costs, impacts and sustainability of telehealth access to medical specialists in rural urgent care centres; modelling the likely costs and impacts of different approaches to meeting the population-based need for bariatric surgery in Australia; examining the impact of market concentration and monopoly in Australian private health insurance; and examining international evidence on the factors driving the growth or emergency department attendances worldwide.
