Abstract
Medical advances, increasing specialisation, rising patient expectations, and the sheer size and diversity of health service provision mean that today's health professionals work in an increasingly complex arena. The wide range of research questions generated by this complexity has encouraged the search for new ways of conducting research. The rapid expansion of research on and about health and health services, and the relatively recent demarcation of a distinct field of “health services research” depend heavily on doctors and other health professionals being investigators, participants, and peer reviewers. Yet some of the most important questions in health services concern the organisation and culture of those who provide health care, such as why the findings of randomised controlled trials are often difficult to apply in day to day clinical practice. The social science methods appropriate to studying such phenomena are very different from the methods familiar to many health professionals.
