The Dutch primary care system has drawn international attention, because of its high performance at low cost. Primary care practices are easily accessible during office hours and collaborate in a unique out-of-hours system. After the reforms in 2006, there are no copayments for patients receiving care in the primary care practice in which they are registered. Financial incentives support the transfer of care from hospital specialists to primary care physicians, and task delegation from primary care physicians to practice nurses. Regional collaborative care groups of primary care practices offer disease management programs. The quality assessment system and the electronic medical record system are predominantly driven by health care professionals. Bottom-up and top-down activities contributed to a successful Dutch primary care system.
