The aim of this guide is to encourage users of international comparisons of health and health care data to consider some of the factors that can influence variation between countries, and to assist them in interpreting the results. Drawing on a range of examples—using health and health care data for Organisation for Economic Co-operation and Development (OECD) countries—this guide highlights the types of question to consider about data quality, the basis for country selection and the techniques used to present the results. It is a general guide, and considering each of the factors presented here may not always be possible.
