The role of private equity in the German outpatient sector

Outpatient medical care in Germany has traditionally been delivered by self-employed physicians, primarily in solo or small group practices. A 2004 reform allowed corporate private investors, to finance outpatient care for the first time. Since then, the establishment of so-called medical care centres (MCCs) has become a staple of public healthcare. From the outset, concerns have been raised that economic interests could conflict with the values of a public health system. However, there is a notable lack of empirical evidence to support this potential conflict. This study seeks to narrow the empirical gap using three methodological approaches: a scoping review, identification of relevant data sources, and a brief case study. Our findings indicate that, to date, there is no empirical evidence suggesting a decline in the quality or scope of healthcare services when MCCs are financed by private equity investors. Nonetheless, the potential emergence of oligopolistic structures and a lack of transparency in provider ownership and structure call for careful regulatory oversight. Policy recommendations include strengthening the data infrastructure with respect to medical outcomes, costs, and provider characteristics (e.g. ownership or affiliations), and safeguarding medical decision-making from profit-driven influence by owners. As rising private investment, including private-equity, in outpatient care is observed across nearly all healthcare systems, an internationally comparative approach is essential.
