The Johns Hopkins Oncology Clinical Information System.

The Johns Hopkins Oncology Center has developed and maintains a clinical information system to support patient care, education, research, and administrative functions. It operates on a dedicated minicomputer (PDP-11) programmed in MUMPS. Clinical information collected includes patient medical status and laboratory values. Data are used daily in patient care and also in support of retrospective and prospective research. The use of the system to manage a large blood pheresis program and to study and treat infectious disease is described. Administrative functions include patient and personnel scheduling, program evaluation, and projects directed toward control of costs.
