Comparative health services research across populations: the unused opportunities in big data.
Large population registries present opportunities to understand the epidemiology of disease, study patters of care, and compare the effectiveness of different care practices. While these 'big data' tempt investigators to examine all available individuals, a targeted approach that restricts the study to an optimal sub-population may yield more relevant insights. We discuss how researchers might adapt their studies existing literature to generate additional insights.
