Overview Why focus on case studies? What are case studies? Focus of the panel Context, Concepts, and Purpose
3 The Context Complexity: health systems and health interventions The setting matters Greater depth of understanding needed Going beyond simple solutions Replicating success Going to scale
4 The Case study •research method or an empirical inquiry that investigates a contemporary phenomenon within its real-life context; •when the boundaries between phenomenon and context are not clearly evident; and •in which multiple sources of evidence are used. Robert K. Yin 1984, p 23 The case as an example for learning about interventions in context Mixed methods Comparative cases to increase potential learning and relevance
More variables than data points. Relies on multiple sources of evidence, requiring the data to converge or triangulate. Theoretical propositions to guide data collection and analysis. Case study research comprises an all-encompassing method – covering the logic of design, data collection techniques, and specific approaches to data analysis
