The use of computer-based patient record systems (CPRS) in the primary care setting will increase significantly over the next few years. Real-time, point-of-care use of such systems must provide adequate payback to justify the intrusion into the provider/patient relationship. The authors describe, through the transition of a legacy system into a state-of-the art system, how such a system might be integrated into the primary care setting. Information flow is organized around an event, such as a patient encounter, or around the patient. The Medical Record (TMR) optimizes the provider/computer interaction through the use of protocols and clinical guidelines. Documentation is enhanced through the use of computer-generated progress notes.
