English abstract

This report uses the research project 'Regional disparities, social segregation and socioeconomic patterning: Where do inequities in access to health care arise?' (REDD) as an example of health services research that makes use of register data. The REDD project aims to evaluate the association between area variation, urbanisation, socioeconomic patterning, the development of social segregation in Finland and their contribution to the changing regional and socioeconomic gradients in health and access to health care. In this report the development and progress of the REDD project are described in order to share experiences on carrying out register-based research in health and health care. The report can be used as material for research training and teaching.

Register-based research differs from other ways of collecting data in that the only hypotheses that can be tested are those for which data already exists or can be constructed. Furthermore, the process of finalising the research questions is an iterative one, determined by the receipt of permission to use the registers selected, the process of data compilation, the extent to which data cleaning yields analysable variables and the technical limitations in developing the actual research datasets.

The report documents the planning and compilation of the REDD study data, problems encountered and solutions chosen and provides brief examples of potential uses of the data. It outlines the challenges and benefits of register-based health care research for researchers planning to use similar data. The report examines the background of the REDD project, its objectives for using register data and the impact of the data sources chosen on the planning of the study settings and the ability to establish the datasets necessary to analyse the questions posed in the research plan. The report includes a brief introduction to the legislation, the relevant statistical register authorities, the process of applying for data and the methods used to compile the data. It illustrates how the final research data sets were formed, provides examples of unexpected defects in the data and draws conclusions on the use of register data in health services research.
