As part of its participation in the international network of health promoting hospitals (HPH), South Tyneside Health Care NHS Trust has initiated a series of sub-projects that are informed by the contemporary evidence-base and the principles of the HPH programme. This paper concerns the first of these sub-projects, whose aim is to establish an equitable and effective Trust-wide system to address smoking in South Tyneside. The ambition is to build a framework for, and foster a culture within which, individuals will be treated considerately, whilst managing "unhealthy" behaviour in such a way as to have a long-term positive impact within the organisation and the surrounding community. This paper will briefly outline the key activities underway, and the manner in which it is hoped this approach to undertaking a HPH sub-project will contribute to sustainable local health improvement, while also supporting the Trust's broader transformation into a truly health promoting organisation.
