Across the Western world, demographic changes have led to healthcare policy trends in the direction of role flexibility, challenging established role boundaries and professional hierarchies. Population ageing is known to be associated with a rise in prevalence of chronic illnesses which, coupled with a reducing workforce, now places much greater demands on healthcare provision. Role flexibility within the health professions has been identified as one of the key innovative practice developments which may mitigate the effects of these demographic changes and help to ensure a sustainable health provision into the future. However, it is clear that policy drives to encourage and enable greater role flexibility among the health professions may also lead to professional resistance and inter-professional role boundary disputes. In the foot and ankle arena, this has been evident in areas such as podiatric surgery, podiatrist prescribing and extended practice in diabetes care, but it is far from unique to podiatry.
