Reforms in Swedish primary care in recent years have focused on increased privatization and competition among providers and increased freedom of choice for citizens. Individuals are allowed to choose among public and private clinics financed by public funds and are expected to compete for listed individuals in a so-called quasi-market. Important objectives behind the introduction of such models are to achieve better responsiveness, accessibility and quality towards individuals. Furthermore, market mechanisms are expected to lead to more efficient use of the public funds that finance the activities. These gains should also take place without negative consequences in terms of increased inequalities in the population. The purpose of the project is to study variation in quality among primary care clinics with regard to conditions among individuals and organizational and structural characteristics among clinics. Analyses of both medical quality and patients' perceptions of quality and responsiveness in primary care, as well as possible contradictions between them, will be studied. In the continued governance and development of Swedish primary care, such issues are important to consider, especially within the framework of models where patients' perceptions of quality and responsiveness are expected to guide individuals' choice of clinic and thus drive the quality of care forward. These issues are also interesting to highlight from a governance perspective given the dual accountability of quasi-markets.
