Impact of a general practitioner-led integrated model of care on the cost of potentially preventable diabetes-related hospitalisations.

<bold>Aim: </bold>To estimate potential savings for Australia's health care system through the implementation of an innovative Beacon model of care for patients with complex diabetes.<bold>Methods: </bold>A prospective controlled trial was conducted comparing a multidisciplinary, community-based, integrated primary-secondary care diabetes service with usual care at a hospital diabetes outpatient clinic. We extracted patient hospitalisation data from the Queensland Hospital Admitted Patient Data Collection and used Australian Refined Diagnosis Related Groups to assign costs to potentially preventable hospitalisations for diabetes.<bold>Results: </bold>327 patients with complex diabetes referred by their general practitioner for specialist outpatient care were included in the analysis. The integrated model of care had potential for national cost savings of $132.5 million per year.<bold>Conclusions: </bold>The differences in hospitalisations attributable to better integrated primary/secondary care can yield large cost savings. Models such as the Beacon are highly relevant to current national health care reform initiatives to improve the continuity and efficiency of care for those with complex chronic disease in primary care.
