Methodologies for Medical Computing. Date Bases and Management Database Management: Applications of MEDLOG, a Microcomputer-Based System for Time-Oriented Clinical Data
Maxwell W. Layard, Dennis J. McShane · Proceedings of the Annual Symposium on Computer Application in Medical Care · 1983
MEDLOG is a clinical data management and analysis system specifically designed to efficiently handle time-oriented clinical data. It employs the basic design of the TOD (Time Oriented Database) system developed at Stanford University. File transpositioning allows very rapid retrieval of data for analysis purposes, so that statistical analysis of research data can be performed on-line. MEDLOG is a completely interactive, menu-driven system. All system functions, including selection of complex time-oriented patient encounter subsets, can be performed without programming. The paper discusses applications of the MEDLOG system to medical research projects involving longitudinal data, including multi-center cancer trials and a large chronic disease databank.
