          Abstract

          Background

          Understanding how new clinical techniques, technologies and other complex interventions become normalized in practice is important to researchers, clinicians, health service managers and policy-makers. This paper presents a model of the normalization of complex interventions.

          Methods

          Between 1995 and 2005 multiple qualitative studies were undertaken. These examined: professional-patient relationships; changing patterns of care; the development, evaluation and implementation of telemedicine and related informatics systems; and the production and utilization of evidence for practice. Data from these studies were subjected to (i) formative re-analysis, leading to sets of analytic propositions; and to (ii) a summative analysis that aimed to build a robust conceptual model of the normalization of complex interventions in health care.

          Results

          A normalization process model that enables analysis of the conditions necessary to support the introduction of complex interventions is presented. The model is defined by four constructs: interactional workability; relational integration; skill set workability and contextual integration. This model can be used to understand the normalization potential of new techniques and technologies in healthcare settings

          Conclusion

          The normalization process model has face validity in (i) assessing the potential for complex interventions to become routinely embedded in everyday clinical work, and (ii) evaluating the factors that promote or inhibit their success and failure in practice.

          The Discovery of Grounded Theory

          <p>Most writing on sociological method has been concerned with how accurate facts can be obtained and how theory can thereby be more rigorously tested. In The Discovery of Grounded Theory, Barney Glaser and Anselm Strauss address the equally Important enterprise of how the discovery of theory from data--systematically obtained and analyzed in social research--can be furthered. The discovery of theory from data--grounded theory--is a major task confronting sociology, for such a theory fits empirical situations, and is understandable to sociologists and laymen alike. Most important, it provides relevant predictions, explanations, interpretations, and applications.</p><p>In Part I of the book, Generation Theory by Comparative Analysis, the authors present a strategy whereby sociologists can facilitate the discovery of grounded theory, both substantive and formal. This strategy involves the systematic choice and study of several comparison groups. In Part II, The Flexible Use of Data, the generation of theory from qualitative, especially documentary, and quantitative data Is considered. In Part III, Implications of Grounded Theory, Glaser and Strauss examine the credibility of grounded theory.</p><p>The Discovery of Grounded Theory is directed toward improving social scientists' capacity for generating theory that will be relevant to their research. While aimed primarily at sociologists, it will be useful to anyone Interested In studying social phenomena--political, educational, economic, industrial-- especially If their studies are based on qualitative data.</p></p>

              Defining quality of care.

              This paper defines quality of health care. We suggest that there are two principal dimensions of quality of care for individual patients; access and effectiveness. In essence, do users get the care they need, and is the care effective when they get it? Within effectiveness, we define two key components--effectiveness of clinical care and effectiveness of inter-personal care. These elements are discussed in terms of the structure of the health care system, processes of care, and outcomes resulting from care. The framework relates quality of care to individual patients and we suggest that quality of care is a concept that is at its most meaningful when applied to the individual user of health care. However, care for individuals must placed in the context of providing health care for populations which introduces additional notions of equity and efficiency. We show how this framework can be of practical value by applying the concepts to a set of quality indicators contained within the UK National Performance Assessment Framework and to a set of widely used indicators in the US (HEDIS). In so doing we emphasise the differences between US and UK measures of quality. Using a conceptual framework to describe the totality of quality of care shows which aspects of care any set of quality indicators actually includes and measures and, and which are not included.
