This paper explores the questions: What has work published in Sociology of Health and Illness contributed to our understanding of 'healthcare organisation'? What are the key research issues for the future? The paper reviews past articles with these questions in mind and uses the first issue of the Journal as a starting point for identifying themes and issues which have remained relevant throughout the first 25 years of its history. I argue that, though the disparate contributions in this area sometimes fail to build on earlier research, when read together they offer a valuable picture of a complex range of healthcare settings and their social organisation. The importance of insights gained from other areas of sociological work is emphasised and some significant examples are identified. The willingness to cross boundaries into other disciplines is also recognised as a strength and this is seen as an important issue for future research, as is increased attention to international comparative research. In similar vein the author argues that the multiplicity of methodological approaches allows the reader to weigh the value of different kinds of data and to look for common underlying patterns of action. It is suggested that future work could usefully revisit past studies, so that we consolidate and accumulate knowledge of the field and avoid a cycle where we continually retread old ground.
