The QUALICOPC study aims to comprehensively evaluate primary care systems in Europe against criteria of quality, equity and costs. The study will provide an answer to the question what strong primary care systems entail and which effects strong primary care systems have on the performance of overall health care systems. The study will collect data in 32 countries in Europe by means of two surveys: one among general practitioners and another among users of patients in primary care. In addition, the sudy will use external data sources, such as: the System of Health Accounts (developed by Eurostat and OECD); the Health Care Quality indicators Project; (by OECD) and the PHAMEU data base (a product of a EU DG Sanco funded European project). The consortium for QUALICOPC represents all the expertise needed for this ambitious study, including links to the external data sources.
