Objectives: To explore physicians' beliefs about a computerized ambulatory medical record system at different stages of its implementation.

Methods: We performed a longitudinal qualitative in-depth interview study (July 2001 to December 2003) in the Hospital Italiano, Buenos Aires, Argentina. Semi-structured interviews were conducted in 20 primary care cardiologists purposively selected before, during and after the system's implementation process (10 interviews per stage).
