title: Public health systems analysis--where the River Kabul meets the River Indus.
abstract: In this paper we review two recent paradigmatic shifts and consider how a two-way flow in innovation has been critical to the emergence of new thinking and new practices. The first area relates to our understanding of the nature of public health systems and the shift from a medical paradigm to a more holistic paradigm which emphasises the social, economic and environmental origins of ill-health and looks to these as key arenas in which to tackle persistent inequalities in populations' health experiences. In respect of this paradigmatic shift, it is argued, developing countries were in advance of their more developed counterparts. Specifically, the Alma Ata Declaration and the Primary Health Care Approach which was central to its implementation pre-figured elements of what was to be called in developed countries The New Public Health such as the need for greater community involvement and recognition of the importance of other sectors in determining health outcomes. But this paradigmatic shift added a new complexity to our understanding which made the identification of appropriate policy responses increasingly difficult. However, a parallel shift was taking place in the cognate field of operational research/systems analysis (OR/SA) which was adding greatly to our ability to analyse and to identify key points of intervention in complex systems. This led to the emergence of new techniques for problem structuring which overcame many of the limitations of formal mathematical models which characterised the old paradigm. In this paradigmatic shift developed countries have led the way, specifically in the new fields of Community Operational Research and Operational Research for Development, but only by drawing strongly on the experience and philosophies to be found in developing countries.
