Health Services Research and Regionalization of Care-From Policy to Practice: the Ontario Experience in Head and Neck Cancer.

Patients being treated at higher case volume hospitals or by higher case volume physicians appear to have better outcomes. This volume-outcome relationship is reviewed for oncologic and non-oncologic surgery with a focus on head and neck oncology. The impact of these research findings on health policy and health-care organization in Ontario, Canada, is then outlined. Lastly, future directions for quality improvement in surgical oncology are reviewed in the context of a universal health-care system. These include surgeon report cards, pre-operative checklists, linking funding and remuneration to the quality of delivered care, and the use of process improvement techniques.
