Preserving social equity in marketized primary care: strategies in Sweden.

A primary care choice reform launched in Sweden in 2010 led to a rapid growth of private providers. Critics feared that the reform would lead to an increased tendency among new, profit-driven, providers, to select patients with lower health risks. Even if open risk selection is prohibited, providers can select patients in more subtle ways, such as establishing their practices in areas with higher health status. This paper investigates to what extent strategies were employed by local governments to avoid risk selection and whether there were any differences between left- and right-wing governments in this regard. Three main strategies were used: risk adjustment of the financial reimbursements on the basis of health and/or socio-economic status of listed patients; design of patient listing systems; and regulatory requirements regarding the scope and content of the services that had to be offered by all providers. Additionally, left-wing local governments were more prone than right-wing governments to adopt risk adjustment strategies at the onset of the reform but these differences diminished over time. The findings of the paper contribute to our understanding of how social inequalities may be avoided in tax-based health care systems when market-like steering models such as patient choice are introduced.
