When implementing health care reforms the pace of change is often lacking behind the expectations of policymakers. In their latest research, NOUS member Alexander Braun, Eva Krczal, and Arleta Franczukowska explore in-depth the experiences of a primary care initiative from the perspective of general practitioners. The physicians‘ perspectives on design features, supporting environment, and acceptance of the pilot are being explored. Enabling and constraining factors that may influence the pace of change of health care reforms are identified. Implications can be drawn for the strategic planning and smooth implementation of the change process.
