ABSTRACT
This review introduces a qualitative methodology called institutional ethnography (IE) to healthcare professionals interested in studying complex social healthcare systems. We provide the historical context in which IE was developed, and explain the principles and terminology in IE for the novice researcher. Through the use of worked examples, the reader will be able to appreciate how IE can be used to approach research questions in the healthcare system that other methods would be unable to answer. We show how IE and qualitative research methods maintain quality and rigour in research findings. We hope to demonstrate to healthcare professionals and researchers that healthcare systems can be analysed as social organisations, and IE may be used to identify and understand how higher-level processes and policies affect day-to-day clinical work. This understanding may allow the formulation and implementation of actionable improvements to solve problems on the ground.
ABSTRACT
Unlike Mendelian epilepsies, complex epilepsies may be due to the effect of several or multiple susceptibility genes. Association studies have been used in the past decade to help identify common genetic variants underpinning complex epilepsies. However, as the data in the Epilepsy Genetic Association Database (epiGAD) show, many of these studies have been negative, or have shown confl icting results. Overall, most putative gene-disease associations are weak. Inadequate sample size is the most likely cause. Multicentre collaborations are vital.
