title: OCIS: 15 years' experience with patient-centered computing.
abstract: In the mid-1970s, the medical and administrative staff of the Oncology Center at Johns Hopkins Hospital recognized a need for a computer-based clinical decision-support system that organized patients' information according to the care continuum, rather than as a series of event-specific data. This is especially important in cancer patients, because of the long periods in which they receive complex medical treatment and the enormous amounts of data generated by extremely ill patients with multiple interrelated diseases. During development of the Oncology Clinical Information System (OCIS), it became apparent that administrative services, research systems, ancillary functions (such as drug and blood product ordering), and financial processes should be integrated with the basic patient-oriented database. With the structured approach used in applications development, new modules were added as the need for additional functions arose. The system has since been moved to a modern network environment with the capacity for client-server processing.
