A qualitative focus group study with a total of 37 general practitioners (GPs) was conducted. To reflect the German speaking and the French speaking part of Switzerland, the focus groups were conducted in both areas. Of the five fo- cus group interviews, three were conducted in Zurich with GPs working in and around Zurich. Two focus group inter- views were conducted in Geneva with GPs working in and around Geneva. All focus groups were composed of six to nine GPs. GPs were recruited by sending a letter to a ran- dom sample of GPs from an existing address database. The GPs who agreed to join the study were allocated to.
